+<h2><a name="INTRODUCTION" id="INTRODUCTION"></a>INTRODUCTION.</h2>
+
+
+<p>Till within a comparatively recent period but little study was given to
+exceptional formations. They were considered as monsters to be shunned,
+as lawless deviations from the ordinary rule, unworthy the attention of
+botanists, or at best as objects of mere curiosity. By those whose
+notions of structure and conformation did not extend beyond the details
+necessary to distinguish one species from another, or to describe the
+salient features of a plant in technical language; whose acquaintance
+with botanical science might almost be said to consist in the
+conventional application of a number of arbitrary terms, or in the
+recollection of a number of names, teratology was regarded as a chaos
+whose meaningless confusion it were vain to attempt to render
+intelligible,&mdash;as a barren field not worth the labour of tillage.</p>
+
+<p>The older botanists, it is true, often made them the basis of satirical
+allusions to the political or religious questions of the day, especially
+about the time of the Reformation, and the artists drew largely upon
+their polemical sympathies in their representations of these anomalies.
+Linn&aelig;us treated of them to some extent in his 'Philosophia,' but it is
+mainly to Angustin Pyramus De Candolle that the credit is due of calling
+attention to the importance of vegetable teratology. This<span class='pagenum'><a name="Page_xxii" id="Page_xxii">[Pg xxii]</a></span> great
+botanist, not only indirectly, but from his personal research into the
+nature of monstrosities, did more than any of his predecessors to rescue
+them from the utter disregard, or at best the contemptuous indifference,
+of the majority of botanists. De Candolle gave a special impetus to
+morphology in general by giving in his adhesion to the morphological
+hypotheses of Goethe. These were no mere figments of the poet's
+imagination, as they were to a large extent based on the actual
+investigation of normal and abnormal organisation by Goethe both alone,
+and also in conjunction with Batsch and Jaeger.</p>
+
+<p>De Candolle's example was contagious. Scarcely a botanist of any
+eminence since his time but has contributed his quota to the records of
+vegetable teratology, in proof of which the names of Humboldt, Robert
+Brown, the De Jussieus, the Saint Hilaires, of Moquin-Tandon, of
+Lindley, and many others, not to mention botanists still living, may be
+cited. To students and amateurs the subject seems always to have
+presented special attractions, probably from the singularity of the
+appearances presented, and from the fact that in many cases the
+examination of individual instances of malformation can be carried on,
+to a large extent, without the lengthened or continuous investigation
+and critical comparative study required by other departments of
+botanical science. Be this as it may, teratology owes a very large
+number of its records to this class of observers.</p>
+
+<p>While the number of scattered papers on vegetable teratology in various
+European languages is so great as to preclude the possibility of
+collating them all, there is no general treatise on the subject in the<span class='pagenum'><a name="Page_xxiii" id="Page_xxiii">[Pg xxiii]</a></span>
+English language, with the exception of Hopkirk's 'Flora Anomala,' a
+book now rarely met with, and withal very imperfect; and this
+notwithstanding that Robert Brown early lent his sanction to the
+doctrines of Goethe, and himself illustrated them by teratological
+observations. In France, besides important papers of Turpin, Geoffroy de
+Saint Hilaire, Brongniart, Kirschleger and others, to which frequent
+allusion is made in the following pages, there is the classic work of
+Moquin-Tandon, which was translated into German by Schauer. Germany has
+also given us the monographs of Batsch, J&aelig;ger, R&oelig;per, Engelmann,
+Schimper, Braun, Fleischer, Wigand, and many others. Switzerland has
+furnished the treatises of the De Candolles, and of Cramer; Belgium,
+those of Morren, &amp;c., all of which, as well as many others that might be
+mentioned, are, with the exception of Moquin-Tandon's 'El&eacute;ments,' to be
+considered as referring to limited portions only and not to the whole
+subject.<a name="FNanchor_1_1" id="FNanchor_1_1"></a><a href="#Footnote_1_1" class="fnanchor">[1]</a></p>
+
+<p>In the compilation of the present volume great use has been made of the
+facts recorded in the works just cited, and especially in those of
+Moquin-Tandon, Engelmann, and Morren. A very large number of
+communications on teratological subjects in the various European
+scientific publications have also been laid under contribution. In most
+cases reference has been given to, and due acknowledgment made of, the
+sources whence information has been gathered. Should any such reference
+be omitted, the neglect must be attributed to inadvertence, not to
+design. In selecting<span class='pagenum'><a name="Page_xxiv" id="Page_xxiv">[Pg xxiv]</a></span> illustrations from the immense number of recorded
+facts, the principle followed has been to choose those which seemed
+either intrinsically the most important, or those which are recorded
+with the most care. In addition to these public sources of information,
+the author has availed himself of every opportunity that has offered
+itself of examining cases of unusual conformation in plants. For many
+such opportunities the author has to thank his friends and
+correspondents. Nor has he less reason to be grateful for the
+suggestions that they have made, and the information they have supplied.
+In particular the writer is desirous of acknowledging his obligations to
+the Society, under whose auspices this work is published, and to Mr. S.
+J. Salter, to whom the book in some degree owes its origin.</p>
+
+<p>The drawings, where not otherwise stated, have been executed either from
+the author's own rough sketches, or from the actual specimens, by Mr. E.
+M. Williams. A large number of woodcuts have also been kindly placed at
+the disposal of the author by the proprietors of the 'Gardeners'
+Chronicle.'<a name="FNanchor_2_2" id="FNanchor_2_2"></a><a href="#Footnote_2_2" class="fnanchor">[2]</a></p>
+
+
+<p class="break">As it is impossible to frame any but a purely arbitrary<span class='pagenum'><a name="Page_xxv" id="Page_xxv">[Pg xxv]</a></span> definition of
+teratology or to trace the limits between variation and malformation, it
+may suffice to say that vegetable teratology comprises the history of
+the irregularities of growth and development in plants, and of the
+causes producing them. These irregularities differ from variations
+mainly in their wider deviation from the customary structure, in their
+more frequent and more obvious dependence on external causes rather than
+on inherent tendency, in their more sudden appearance, and lastly in
+their smaller liability to be transmitted by inheritance.</p>
+
+<p>What may be termed normal morphology includes the study of the form,
+arrangement, size and other characteristic attributes of the several
+parts of plants, their internal structure, and the precise relation one
+form bears to another. In order the more thoroughly to investigate these
+matters it is necessary to consider the mode of growth, and specially
+the plan of evolution or development of each organ. This is the more
+needful owing to the common origin of things ultimately very different
+one from the other, and to the presence of organs which, in the adult
+state, are identical or nearly so in aspect, but which nevertheless are
+very unlike in the early stages of their existence.<a name="FNanchor_3_3" id="FNanchor_3_3"></a><a href="#Footnote_3_3" class="fnanchor">[3]</a> Following Goethe,
+these changes in the course of development are sometimes called
+metamorphoses. In this way Agardh<a name="FNanchor_4_4" id="FNanchor_4_4"></a><a href="#Footnote_4_4" class="fnanchor">[4]</a> admits three kinds of
+metamorphosis, which he characterises as: 1st. Successive metamorphoses,
+or those changes in the course of evolution which each individual organ
+undergoes in<span class='pagenum'><a name="Page_xxvi" id="Page_xxvi">[Pg xxvi]</a></span> its passage from the embryonic to the adult condition, or
+from the simple and incomplete to the complex and perfect. 2. Ascending
+metamorphoses, including those changes of form manifested in the same
+adult organism by the several parts of which it consists&mdash;those parts
+being typically identical or homologous, such as the parts of the
+flower, or, in animals, the vertebr&aelig;, &amp;c. 3. Collateral metamorphoses,
+comprising those permutations of form and function manifested in
+homologous organs in the different groups of organisms, classes, orders,
+genera, species, &amp;c.</p>
+
+<p>Thus, in the first instance, we have a comparative examination of the
+form of each or any separate part of the same individual at different
+epochs in its life-history; in the second we have a similar comparison
+instituted between the several parts of the same organism which
+originally were identical in appearance, but which have in course of
+evolution altered in character. In the third form we have the
+comparative view not of one organ at different times, nor of the several
+parts of one organism, but of the constituent elements pertaining to
+those aggregates of individuals to which naturalists apply the terms
+classes, orders, &amp;c.</p>
+
+<p>In successive metamorphosis we have a measure of the amount of change
+and of the perfection of structure to which each separate organ attains.</p>
+
+<p>In ascending metamorphosis we have a gauge of the extent of alteration
+that may take place in the several homologous organs under existing
+circumstances.</p>
+
+<p>In collateral metamorphosis, in the same way, we have an illustration of
+the degree of change possible in aggregates of organisms under existing
+circumstances.</p><p><span class='pagenum'><a name="Page_xxvii" id="Page_xxvii">[Pg xxvii]</a></span></p>
+
+<p>Now it is clear that from an investigation of all three classes just
+mentioned, we shall be able to gain an idea of those points which are
+common to all parts, to all individuals or to all aggregates, and those
+that are peculiar to some of them, and, by eliminating the one from the
+other, we shall arrive at conclusions which will be more or less
+generally accurate or applicable, according to the ability of the
+student and the extent to which the comparative analysis is earned. It
+is thus that morphologists have been enabled to frame types or standards
+of reference, and systematists to collocate the organisms they deal with
+into groups. These standards and groups are more or less artificial
+(none can be entirely natural) in proportion to the amount of knowledge
+possessed by their framers, and the use they make of it.</p>
+
+<p>From this point of view teratological metamorphosis of all three kinds
+demands as much attention as that which is called normal. We can have no
+thorough knowledge of an organ, of an individual which is an aggregate
+of organs, or of an aggregate of individuals of whatever degree, unless
+we know approximately, at least, what are the limits of each. It is not
+possible to trace these limits accurately in the case of natural
+science, but the larger our knowledge and the wider our generalisations,
+the closer will be our approach to the truth.</p>
+
+
+<p class="break">The most satisfactory classification of malformations would be one
+founded upon the nature of the causes inducing the several changes.
+Thus, in all organised beings, there is a process of growth, mere
+increase in bulk as it were, and a process of evolution or
+metamorphosis,<span class='pagenum'><a name="Page_xxviii" id="Page_xxviii">[Pg xxviii]</a></span> in accordance with which certain parts assume a
+different form from the rest, in order the better to fit them for the
+performance of different offices. Should growth and development be
+uniform and regular, that is in accordance with what is habitual in any
+particular species, there is no monstrosity, but if either growth or
+development be in any way irregular, malformation results. Hence,
+theoretically, the best way of grouping cases of malformation would be
+according as they are the consequences of:&mdash;1st. Arrest of Growth;
+2ndly. Excessive Growth; 3rdly. Arrest of Development; 4thly, of
+Excessive or Irregular Development.</p>
+
+<p>In practice, however, there are so many objections to this plan that it
+has not been found practicable to carry it out. The inability arises to
+a great extent from our ignorance of what should be attributed to arrest
+of growth, what to excess of development, and so on. Moreover, a student
+with a malformed plant before him must necessarily ascertain in what way
+it is malformed before he can understand how it became so, and for this
+purpose any scheme that will enable him readily to detect the kind of
+monstrosity he is examining, even though it be confessedly artificial
+and imperfect will be better than a more philosophical arrangement which
+circumstances prevent him from employing.</p>
+
+<p>The plan followed in this volume is a slight modification of that
+adopted by Moquin-Tandon, and with several additions. In it the aim is
+to place before the student certain salient and easily recognisable
+points by reference to which the desired information can readily be
+found. Under each subdivision will be found general explanatory remarks,
+illustrative details, and usually a summary of the more important facts<span class='pagenum'><a name="Page_xxix" id="Page_xxix">[Pg xxix]</a></span>
+and the inferences to be derived from them. Bibliographical references
+and lists of the plants most frequently affected with particular
+malformations are also given. In reference to both these points it must
+be remembered that absolute completeness is not aimed at; had such
+fullness of detail been possible of attainment it would have
+necessitated for its publication a much larger volume than the
+present.<a name="FNanchor_5_5" id="FNanchor_5_5"></a><a href="#Footnote_5_5" class="fnanchor">[5]</a> It is hoped that both the lists of books and of plants are
+sufficiently full for all general purposes.<a name="FNanchor_6_6" id="FNanchor_6_6"></a><a href="#Footnote_6_6" class="fnanchor">[6]</a></p>
+
+<p>In the enumeration of plants affected with various malformations the !
+denotes that the writer has himself seen examples of the deviation in
+question in the particular plant named, while the prefix of the *
+indicates that the malformation occurs with special frequency in the
+particular plant to which the sign is attached.</p>
+
+<p>Teratological alterations are rarely isolated phenomena, far more
+generally they are associated with other and often compensatory changes.
+Hence it is often necessary, in studying any given malformation, to
+refer to two or more subdivisions, and in this way a certain amount of
+repetition becomes unavoidable. The details<span class='pagenum'><a name="Page_xxx" id="Page_xxx">[Pg xxx]</a></span> of the several cases of
+malformation given in these pages are generally arranged according to
+their apparent degree of importance. Thus, in a case of prolification
+associated with multiplication of the petals, the former change is a
+greater deviation from the customary form than the latter, hence
+reference should be made, in the first instance, to the sections
+treating on prolification, and afterwards to those on multiplication. To
+facilitate such research, numerous cross references are supplied.</p>
+
+<p>In the investigation of teratological phenomena constant reference must
+be made to the normal condition, and <i>vice vers&acirc;</i>, else neither the one
+nor the other can be thoroughly understood. It cannot, however, be
+overlooked that the form and arrangement called normal are often merely
+those which are the most common, while the abnormal or unusual
+arrangement is often more in consonance with that considered to be
+typical than the ordinary one. Thus, too, it is often found that the
+structural arrangements, which in one flower are normal, are in another
+abnormal, in so far that they are not usual in that particular instance.</p>
+
+<p>For purposes of reference, a standard of comparison is required; and
+this standard, so long as its nature is not overlooked, may, indeed must
+be, to some extent, an arbitrary one. Thus in the phanerogamous plants
+there is assumed to exist, in all cases, an axis (stem, branches, roots,
+thalamus, &amp;c.), bearing leaves and flowers. These latter consist of four
+whorls, calyx, corolla, stamens, and pistils, each whorl consisting of
+so many separate pieces in determinate position and numbers, and of
+regular proportionate size. A very close approach to such a flower
+occurs<span class='pagenum'><a name="Page_xxxi" id="Page_xxxi">[Pg xxxi]</a></span> normally in <i>Limnanthes</i> and <i>Crassula</i>, and, indeed, in a large
+proportion of all flowers in an early stage of development. To a
+standard type, such as just mentioned, all the varied forms that are met
+with, either in normal or abnormal morphology, may be referred by
+bearing in mind the different modifications and adaptations that the
+organs have to undergo in the course of their development. Some parts
+after a time may cease to grow, others may grow in an inordinate degree,
+and so on; and thus, great as may be the ultimate divergences from the
+assumed standard, they may all readily be explained by the operation,
+simply or conjointly, of some of the four principal causes of
+malformation before alluded to. The fact that so many and such varied
+changes can thus readily be explained is not only a matter of
+convenience, but may be taken as evidence that the standard of reference
+is not wholly arbitrary and artificial, but that it is a close
+approximation to the truth.</p>
+
+<p>It has already been said that an arrangement like that here considered
+as typical is natural to some flowers in their adult state, and to a
+vast number in their immature condition. It would be no extravagant
+hypothesis to surmise that this was the primitive structure of the
+flower in the higher plants. Variations from it may have arisen in
+course of time, owing to the action of an inherent tendency to vary, or
+from external circumstances and varied requirements which may have
+induced corresponding adaptations, and which may have been transmitted
+in accordance with the principle of hereditary transmission. This
+hypothesis necessarily implies a prior simplicity of organisation, of
+which, indeed, there is sufficient proof; many cases<span class='pagenum'><a name="Page_xxxii" id="Page_xxxii">[Pg xxxii]</a></span> of malformation
+can thus be considered as so many reversions to the ancestral form.</p>
+
+<p>Thus, teratology often serves as an aid in the study of morphology in
+general, and also in that of special groups of plants, and hence may
+even be of assistance in the determination of affinities. In any case
+the data supplied by teratology require to be used with caution and in
+conjunction with those derived from the study of development and from
+analogy. It is even possible that some malformations, especially when
+they acquire a permanent nature and become capable of reproducing
+themselves by seed, may be the starting-point of new species, as they
+assuredly are of new races, and between a race and a species he would be
+a bold man who would undertake to draw a hard and fast line.<a name="FNanchor_7_7" id="FNanchor_7_7"></a><a href="#Footnote_7_7" class="fnanchor">[7]</a></p>
+
+<p>Discredit has been cast on teratology because it has been incautiously
+used. At one time it was made to prove almost everything; what wonder
+that by some, now-a-days, it is held to prove nothing. True the evidence
+it affords is sometimes negative, often conflicting, but it is so rather
+from imperfect interpretation than from any intrinsic worthlessness. If
+misused the fault lies with the disciple, not with Nature.</p>
+
+<p>Teratology as a guide to the solution of morphological problems has been
+especially disparaged in contrast with organogeny, but unfairly so.
+There is no reason to exalt or to disparage either at the expense of the
+other. Both should receive the attention they demand. The study of
+development shows the primitive condition and gradual evolution of parts
+in any<span class='pagenum'><a name="Page_xxxiii" id="Page_xxxiii">[Pg xxxiii]</a></span> given individual or species; it carries us back some stages
+further in the history of particular organisms, but so also does
+teratology. Many cases of arrest of development show the mode of growth
+and evolution more distinctly, and with much greater ease to the
+observer, than does the investigation of the evolution of organs under
+natural circumstances. Organogeny by no means necessarily, or always,
+gives us an insight into the principles regulating the construction of
+flowers in general. It gives us no archetype except in those
+comparatively rare cases where primordial symmetry and regularity exist.
+When an explanation of the irregularity of development in these early
+stages of the plant's history is required, recourse must be had to the
+inferences and deductions drawn from teratological investigations and
+from the comparative study of allied forms precisely as in the case of
+adult flowers.</p>
+
+<p>The study of development is of the highest importance in the examination
+of plants as individuals, but in regard to comparative anatomy and
+morphology, and specially in its relation to the study of vegetable
+homology it has no superiority over teratology. Those who hold the
+contrary opinion do so, apparently, because they overlook the fact that
+there is no distinction, save of degree, to be drawn between the laws
+regulating normal organisation, and those by which so-called abnormal
+formations are regulated.</p>
+
+<p>It is sometimes said, and not wholly without truth, that teratology, as
+it stands at present, is little more than a record of facts, but in
+proportion as the laws that regulate normal growth are better
+understood, so will the knowledge of those that govern the so-called
+monstrous formations increase. Sufficient has<span class='pagenum'><a name="Page_xxxiv" id="Page_xxxiv">[Pg xxxiv]</a></span> been already said to
+prove that there is no intrinsic difference between the laws of growth
+in the two cases. As our knowledge increases we shall be enabled to
+ascertain approximately of what extent of variation a given form is
+capable, under given conditions, and to refer all formations now
+considered anomalous to a few well-defined forms. Already teratology has
+done much towards showing the erroneous nature of many morphological
+statements that still pass current in our text-books, though their
+fallacy has been demonstrated again and again. Thus organs are said to
+be fused which were never separate, disjunctions and separations are
+assigned to parts that were never joined, adhesions and cohesions are
+spoken of in cases where, from the nature of things, neither adhesion
+nor cohesion could have existed. Some organs are said to be atrophied
+which were never larger and more fully developed than they now are, and
+so on. So long as these expressions are used in a merely conventional
+sense and for purposes of artificial classification or convenience, well
+and good, but let us not delude ourselves that we are thus contributing
+to the philosophical study either of the conformation of plants or of
+the affinities existing between them. What hope is there that we shall
+ever gain clear conceptions as to the former, as long as we tie
+ourselves down to formulas which are the expressions of facts as they
+appear to be, rather than as they really are? What chance is there of
+our attaining to comprehensive and accurate views of the genealogy and
+affinities of plants as long as we are restricted by false notions as to
+the conformation and mutual relation of their parts?<a name="FNanchor_8_8" id="FNanchor_8_8"></a><a href="#Footnote_8_8" class="fnanchor">[8]</a></p><p><span class='pagenum'><a name="Page_xxxv" id="Page_xxxv">[Pg xxxv]</a></span></p>
+
+<p>That teratology may serve the purposes of systematic botany to a greater
+extent than might at first be supposed becomes obvious from a
+consideration of such facts as are mentioned under the head of Peloria,
+while the presence of rudimentary organs, or the occasional appearance
+of additional parts, or other changes, may, and often do, afford a clue
+to the relationship existing between plants&mdash;a relationship that might
+otherwise be unsuspected. So, too, some of the alterations met with
+appear susceptible of no other explanations than that they are
+reversions to some pre-existing form, or, at any rate, that they are
+manifestations of a phase of the plant affected different from that
+which is habitual, and due, as it were, to a sort of allotropism.</p>
+
+<p>The mutations and perversions of form, associated as they commonly are
+with corresponding changes of function, show the connection between
+teratology and physiology&mdash;a connection which is seen to be the more
+intimate when viewed in the light afforded by the writings and
+experiments of G&aelig;rtner, Sprengel, and St. Hilaire, and, in our own
+times, especially by the writings and experiments of Mr. Darwin, whose
+works on the 'Origin of Species,' and particularly on the 'Variation of
+Animals and Plants under Domestication' comprise so large a collection
+of facts for the<span class='pagenum'><a name="Page_xxxvi" id="Page_xxxvi">[Pg xxxvi]</a></span> use of students in most departments of biology. It
+will suffice to allude, in support of these statements, to the writings
+of Mr. Darwin on such subjects as rudimentary organs, the use or disuse
+of certain parts according to circumstances, the frequently observed
+tendency of some flowers to become structurally unisexual, the liability
+of other flowers perfectly organised to become functionally imperfect,
+at least so far as any reciprocal action of the organs of the same

+minute accuracy of detail by our great physiologist.</p>
+
+<p>In the following pages alterations of function, unless attended by
+corresponding alterations of form, are either only incidentally alluded
+to, or are wholly passed over; such, for instance, as alterations in the
+period of flowering, in the duration of the several organs, and so
+forth.<a name="FNanchor_9_9" id="FNanchor_9_9"></a><a href="#Footnote_9_9" class="fnanchor">[9]</a> Pathological changes, lesions caused by insect puncture or
+other causes, also find no place in this book, unless the changes are of
+such a character as to admit of definite comparison with normal
+conformation. Usually such changes are entirely heteromorphous, and, as
+it were, foreign to the natural organisation.</p>
+
+<p>The practical applications of teratology deserve the attention of those
+cultivators who are concerned in the embellishment of our gardens and
+the supply<span class='pagenum'><a name="Page_xxxvii" id="Page_xxxvii">[Pg xxxvii]</a></span> of our tables. The florist lays down a certain arbitrary
+standard of perfection, and attempts to make flowers conform to that
+model. Whether it be in good taste or not to value all flowers, in
+proportion as they accord with an artificial and comparatively inelastic
+standard of this kind, we need not stop to enquire; suffice it to say,
+that taking the matter in its broadest sense, the aim of the florist is
+to produce large, symmetrical flowers, brightly and purely coloured, or
+if parti-coloured, the colours must be distinct, harmonious, or
+contrasted. When all this is done, the flower, in most instances,
+becomes 'monstrous' of the eyes in the botanist, though all the more
+interesting to the student of morphology on that account. In like manner
+the double flowers, the "breaks," the "sports" which the florist
+cultivates so anxiously, are all of them greater or less deviations from
+the ordinary form, while the broccolies, the cabbages, and many other
+products of our kitchen gardens and fields owe the estimation in which
+they are held entirely to those peculiarities which, by an unhappy
+application of words, are called monstrous by botanists. Grafting,
+layering, the "striking" of cuttings, the formation of adventitious
+roots and buds, processes on which the cultivator so greatly relies for
+the propagation and extension of his plants, are also matters with which
+teratology concerns itself. Again the difficulty experienced
+occasionally in getting vines, strawberries, &amp;c., to set properly, may
+sometimes be accounted for by that inherent tendency which some plants
+possess of exchanging an hermaphrodite for a unisexual condition.</p>
+
+<p>For reasons then of direct practical utility, no<span class='pagenum'><a name="Page_xxxviii" id="Page_xxxviii">[Pg xxxviii]</a></span> less than on purely
+scientific grounds, it is desirable to study these irregularities of
+growth, their nature, limits, and inducing causes; and to this end it is
+hoped the present work may, in some degree, contribute.</p>

+
+DEVIATIONS FROM THE ORDINARY ARRANGEMENT OF ORGANS.</h2>
+
+
+<p>As full details relating to the disposition or arrangement of the
+general organs of flowering plants are given in all the ordinary
+text-books, it is only necessary in this place to allude to the main
+facts at present known, and which serve as the standard of comparison
+with which all morphological changes are compared.</p>
+
+<p>Even in the case of the roots, which appear to be very irregular in
+their ramification, it has been found that, in the first instance at
+least, the rootlets or fibrils are arranged in regular order one over
+another, in a certain determinate number of vertical ranks, generally
+either in two or in four, sometimes in three or in five series. This
+regularity of arrangement (Rhizotaxy), first carefully studied by M.
+Clos, is connected with the disposition of the fibro-vascular bundles in
+the body of the root. This primitive regularity is soon lost as the
+plant grows.</p>
+
+<p>In the case of the leaves there are two principal<span class='pagenum'><a name="Page_2" id="Page_2">[Pg 2]</a></span> modes of arrangement,
+dependent, as it would seem, on their simultaneous or on their
+successive development; thus, if two leaves on opposite sides of the
+stem are developed at the same time, we have the arrangement called
+opposite; if there are more than two, the disposition is then called
+verticillate or whorled. On the other hand, if the leaves are developed
+in succession, one after the other, they are found to emerge from the
+stem in a spiral direction. In either case the leaves are arranged in a
+certain regular manner, according to what are called the laws of
+Phyllotaxis, which need not be entered into fully here; but in order the
+better to estimate the teratological changes which take place, it may be
+well to allude to the following circumstances relating to the
+alternation of parts. The effect of this alternation is such, that no
+two adjacent leaves stand directly over or in front one of the other,
+but a little to one side or a little higher up. Now, in the alternate
+arrangement the successive leaves of each spiral cycle alternate one
+with another till the coil is completed. For the sake of clearness this
+may be illustrated thus:&mdash;Suppose the spiral cycle to comprise five
+leaves, numbered 1, 2, 3, 4, 5, then 2 would intervene between 1 and 3,
+and so on, while the sixth leaf would be the commencement of a new
+series, and would be placed exactly over 1. This arrangement may be thus
+formularised:</p>
+
+<pre>
+      6      7      8       9      10
+      1      2      3       4       5
+</pre>
+
+<p>In the verticillate or simultaneous arrangement of leaves the case is
+somewhat different. Let us suppose a whorl of eight leaves, surmounted
+by a similar whorl of eight. In such a case it will generally be found<span class='pagenum'><a name="Page_3" id="Page_3">[Pg 3]</a></span>
+that the whorls alternate one with another, as may be represented by
+this symbol:</p>
+
+<pre>
+     9     10     11     12     13     14     15     16
+  1     2      3      4      5      6      7      8
+</pre>
+
+<p>The simplest illustration of this arrangement is seen in the case of
+decussate leaves, where those organs are placed in pairs, and the pairs
+cross one another at right angles. This may be expressed by the
+following symbol:</p>
+
+<pre>
+         7      8
+      5      6
+         3      4
+      1      2
+</pre>
+
+<p>Thus, while in both the annular and the spiral modes of development the
+individual members of each complete series necessarily alternate one
+with another, in the former case the series themselves alternate, while
+in the successive arrangement they are placed directly one over the
+other. There are, of course, exceptions, but the rule is as has been
+stated, and the effect is to prevent one leaf from interfering with the
+development and growth of its neighbours.</p>
+
+<p>In the case of the whorled or simultaneous arrangement the conditions of
+growth must be uniform on all sides, but in the successive or spiral
+disposition the conditions influencing growth act with unequal force, on
+different sides of the stem, at the same time. In the whorl there is an
+illustration of radiating symmetry, while in the spiral arrangement
+there is a transition to the bilateral symmetry. There are frequent
+passages from one to the other even under normal circumstances; thus,
+while the one arrangement<span class='pagenum'><a name="Page_4" id="Page_4">[Pg 4]</a></span> obtains in the ordinary leaves, the parts of
+the flower may be disposed according to the other method. In the annular
+disposition it generally happens that the rings are separated one from
+the other by the development of the stem between them, the internodes
+between the constituent leaves themselves of course being undeveloped;
+on the other hand, in the spiral or successive arrangement there is no
+such alternate growth and arrest of growth of the stem between the
+leaves, or between successive cycles, but the growth is, under favorable
+conditions, continuous&mdash;leaf is separated from leaf, and cycle from
+cycle, by the continually elongating stem. Thus, the two modes of growth
+correspond precisely with those observed in the case of definite and
+indefinite inflorescence respectively.</p>

+   <p class="caption"><span class="smcap">Fig. 1.</span>&mdash;Diagram showing the arrangement of parts in a
+complete, regular, pentamerous flower: <i>s</i>, sepals; <i>p</i>, petals; <i>st</i>,
+stamens; <i>o</i>, ovaries.</p>
+</div>
+
+<p>The same arrangements, that are observed in the disposition of the
+leaves, apply equally well to the several parts of the flower; thus, in
+what is for convenience considered the typical flower, there is a calyx
+of five or more distinct sepals, equal in size, and arranged in a whorl,
+a corolla of a similar number of petals alternating with the sepals,
+five stamens placed in the same position with reference to the petals,
+and five carpels alternating with the stamens. Throughout this book this
+arrangement is taken as the standard of reference. Nevertheless the
+spiral order does occur in the floral leaves as well as in those of the
+stem; it often happens, especially when the organs are numerous, that
+they form spiral series;<span class='pagenum'><a name="Page_5" id="Page_5">[Pg 5]</a></span> and the same holds good very generally, when
+the parts of the flower are uneven in number, as in the very common
+quincuncial arrangement of the sepals, &amp;c.</p>
+
+<p>To these general remarks, intended to show the agreement between the
+disposition of the leaves of the stem and those of the flower, it is
+merely necessary to add that the arrangement of the placentas, as well
+as that of the ovules borne on them, is also definite, and takes place
+according to methods explained in all the text-books, and on which,
+therefore, it is not necessary to dilate in this place.</p>
+
+<p>The branches of the stem or axis correspond for the most part in
+disposition with that of the leaves from the axils of which they
+originate, subject, however, to numerous disturbing causes, and to
+alterations from the usual or typical order brought about by the
+development of buds. These latter organs, as it seems, may be found in
+almost any situation, though their ordinary position is in the axil of a
+leaf or at the end of a stem or branch.</p>
+
+<p>The points just mentioned are of primary importance in structural
+botany, and as such are seized on not only by the morphologist, but by
+the systematic botanist, who finds in them the characters by which he
+may separate one group from another. Thanks to the labours of those
+observers who have devoted their attention to that difficult but most
+important branch of study, organogeny, or the investigation of the
+development of the various organs, and to the researches of the students
+of comparative anatomy or morphology, the main principles regulating the
+arrangement and form of the organs of flowering plants seem to be fairly
+well<span class='pagenum'><a name="Page_6" id="Page_6">[Pg 6]</a></span> established, though in matters of detail much remains to be
+cleared up, even in such important points as the share which the axis
+takes in the construction of the flower and fruit, the nature of the
+placenta, the construction of the ovules, and other points.</p>
+
+<p>The facts already known justify the adoption of a standard or typical
+arrangement as just mentioned. The intrinsic value of this type is shown
+by the facility with which all varieties of form or arrangement may be
+explained by reference to certain modifications of it. It must, however,
+be considered as an abstraction, and should be looked on in the light
+rather of a scaffolding, which enables us to see the building and its
+several parts, than of the edifice itself, but which latter, from our
+imperfect knowledge and limited powers, we could not see without some
+such assistance.</p>
+
+<p>The typical form may be, hypothetically at least, considered as the
+primitive one transmitted by hereditary descent from generation to
+generation, and modified to suit the requirements of the individual, or
+in accordance with circumstances. If it be borne in mind that it is but
+an artificial contrivance, more or less true&mdash;a means to an end, and not
+the end itself&mdash;no harm will arise from its employment; and as knowledge
+increases, or as circumstances demand, the hypothetical type can be
+replaced by another more in accordance with the actual state of science.</p>
+
+
+<p class="break">Teratological changes in the arrangement of organs depend upon arrest of
+growth, as when parts usually spirally arranged remain verticillate,
+owing to the non-development of the internodes, or to excessive growth,
+or development; but in many instances it is<span class='pagenum'><a name="Page_7" id="Page_7">[Pg 7]</a></span> impossible, without
+studying the development of the malformed flower, to ascertain whether
+the altered arrangement is due to an excessive or to a diminished
+action. Practically, however, it is of comparatively little importance
+to know whether, say, the isolation of parts, that are usually combined
+together, is congenital (<i>i.e.</i> the result of an arrest of growth
+preventing their union), or whether it be due to a separation of parts
+primitively undivided; the effect remains the same, though the cause may
+have been very different.</p>
+
+<p>The principal alterations to be mentioned under this head may therefore
+be conveniently arranged under the following categories:&mdash;Union,
+Independence, Displacement, Prolification, Heterotaxy, and Heterogamy.</p>

+<h3><a name="PART_I" id="PART_I"></a>PART I.<br />
+
+UNION OF ORGANS.</h3>
+
+
+<p>The union of parts, usually separate in their adult condition, is of
+very common occurrence as a malformation. The instances of its
+manifestation admit of being grouped under the heads of Cohesion, where
+parts of the same whorl, or of the same organ, are united together; and
+of Adhesion, where the union takes place between members of different
+whorls, or between two or more ordinarily wholly detached and distinct
+parts. In either case, the apparent union may be congenital (that is,
+the result of a primitive integrity or a lack of separation), or it may
+really consist in a coalition of parts originally distinct and separate.
+In practice it is not always easy to distinguish between these two
+different conditions. Indeed, in most cases it cannot be done without
+tracing the development of the flower throughout all its stages. It is
+needless to make more than a passing allusion to the frequency with
+which both congenital integrity or subsequent coalescence of organs
+exist under ordinary circumstances. Considered as a teratological
+phenomenon, union admits of being grouped into several subdivisions,
+such as Cohesion, Adhesion, Synanthy, Syncarpy, Synophty, &amp;c. Each of
+these subdivisions will be separately treated, but it maybe here said
+that, in all or any case, the degree of fusion may be very slight, or it
+may be so perfect that there may be a complete amalgamation of two or
+more parts, while to all outward appearance the organ may be single.
+The<span class='pagenum'><a name="Page_9" id="Page_9">[Pg 9]</a></span> column of Orchids may be referred to as an illustration under
+natural circumstances of the complete union of many usually distinct
+parts.</p>
+
+<p>In the uncertainty that exists in many cases as to the real nature of
+the occurrence, it would be idle to attempt to explain the causes of
+fusions. It is clear, however, that an arrest of development will tend
+towards the maintenance of primordial integrity (congenital fusion), and
+that pressure will induce the coalition of organs primarily distinct.</p>
+
+
+
+
+<h4><a name="CHAPTER_I" id="CHAPTER_I"></a>CHAPTER I.<br />
+
+COHESION.</h4>
+
+
+<p>Following Augustin Pyranius De Candolle, botanists have applied the term
+cohesion to the coalescence of parts of the same organ or of members of
+the same whorl; for instance, to the union of the sepals in a
+gamosepalous calyx, or of the petals in a gamopetalous corolla. It may
+arise either from a union between organs originally distinct, or more
+frequently from a want of separation between parts, which under general
+circumstances become divided during their development. Nothing is more
+common as a normal occurrence, while viewed as a teratological
+phenomenon it is also very frequent. For the purposes of convenience it
+admits of subdivision into those cases wherein the union takes place
+between the branches of the same plant, or between the margins of the
+same leaf-organ, or between those of different members of the same
+whorl.</p>
+
+<p><b>Cohesion between the axes of the same plant.</b>&mdash;This cohesion may occur in
+various manners. Firstly. The branches of the main stem may become
+united one to the other. Secondly. Two or more stems become joined
+together.<span class='pagenum'><a name="Page_10" id="Page_10">[Pg 10]</a></span> Thirdly. The branches become united to the stem; or, lastly,
+the roots may become fused one with another.</p>
+
+<div class="center">

+<p class="caption"> <span class="smcap">Fig. 2</span>&mdash;Cohesion of two branches in <i>Dipsacus sylvestris</i>.</p>
+</div>
+
+<p>The first of these is most commonly met with, doubtless owing to the
+number of the branches and the facilities for their union. An
+illustration of it is afforded by the figure (fig. 2), showing cohesion
+affecting the branches of a teazle (<i>Dipsacus sylvestris</i>). Union of the
+branches may be the result of an original cohesion of the buds, while in
+other cases the fusion does not take place until after development has
+proceeded to some extent. Of this latter kind illustrations are common
+where the branches are in close approximation; if the bark be removed by
+friction the two surfaces are very likely to become united (natural
+grafting). Such a union of the branches is very common in the ivy, the
+elder, the beech, and other plants. It may take place in various<span class='pagenum'><a name="Page_11" id="Page_11">[Pg 11]</a></span>
+directions, lengthwise, obliquely, or transversely, according to
+circumstances. This mode of union belongs, perhaps, rather to the domain
+of pathology than of teratology. Some of the instances that have been
+recorded of very large trees, such as the chestnut of Mount &AElig;tna, are
+really cases where fusion has taken place between several of the
+branches, or suckers, thrown out from the same original stem.<a name="FNanchor_10_10" id="FNanchor_10_10"></a><a href="#Footnote_10_10" class="fnanchor">[10]</a> The
+same process of grafting occurs sometimes in the roots, as in <i>Taxus
+baccata</i> mentioned by Moquin, and also in the aerial roots of many of
+the tropical climbing plants, such as <i>Clusia rosea</i>, &amp;c.</p>

+
+<p><b>Fasciation.</b>&mdash;In the preceding instances of union between the branches,
+&amp;c., the actual number of the fused parts is not increased; but if it
+happen that an unusual number of buds be formed in close apposition, so
+that they are liable to be compressed during their growth, union is very
+likely to take place, the more so from the softness of the young
+tissues. In this way it is probable that what is termed fasciation is
+brought<span class='pagenum'><a name="Page_12" id="Page_12">[Pg 12]</a></span> about. This is one of the most common of all malformations, and
+seems to affect certain plants more frequently than others. In its
+simplest form it consists of a flat, ribbon-like expansion of the stem
+or branch; cylindrical below, the branches gradually lose their pristine
+form, and assume the flattened condition.</p>

+</div>
+
+<p>Very generally the surface is striated by the prominence of the woody
+fibres which, running parallel for a time, converge or diverge at the
+summit according to the shape of the branch. If the rate of growth be
+equal, or nearly so, on both sides, the stem retains its straight
+direction, but it more generally happens that the growth on one side is
+more rapid and more vigorous<span class='pagenum'><a name="Page_13" id="Page_13">[Pg 13]</a></span> than on the other, and hence arises that
+curvature of the fasciated branch so commonly met with, <i>e.g.</i> in the
+ash (<i>Fraxinus</i>), wherein it has been likened to a shepherd's crook. It
+is probable that almost any plant may present this change. It occurs
+alike in herbaceous and in woody plants, originating in the latter case
+while the branches are still soft. It may be remarked that, in the case
+of herbaceous plants, the fasciation always affects the principal stem,
+while, on the other hand, in the case of trees and shrubs the deformity
+occurs most frequently in the branches; thus, while in<span class='pagenum'><a name="Page_14" id="Page_14">[Pg 14]</a></span> the former it
+may be said that the whole of the stem is more or less affected, in the
+latter it is rare to see more than one or two branches of the same tree
+thus deformed. It is a common thing for the fasciated branch to divide
+at the summit into a number of subdivisions. These latter may be
+deformed like the parent branch, or they may resume the ordinary aspect

+</div>
+
+<p>Sometimes the flattened stem is destitute of buds, at other times, these
+organs are scattered irregularly over its surface or are crowded
+together in a sort of<span class='pagenum'><a name="Page_15" id="Page_15">[Pg 15]</a></span> crest along the apex. When, as often happens, the
+deformity is accompanied with a twisting of the branch spirally, the
+buds may be placed irregularly, or in other cases along the free edge of
+the spiral curve. In a specimen of <i>Bupleurum falcatum</i> mentioned by
+Moquin the spiral arrangement of the leaves was replaced by a series of
+perfect whorls, each consisting of five, six, seven, or eight segments,
+and there was a flower-stalk in the axil of each leaf.</p>
+
+<p>When flowers are borne on these fasciated stems they are generally
+altered in structure; sometimes the thalamus itself becomes more or less
+fasciated or flattened, and the different organs of the flower are
+arranged on an elliptical axis. A case of this nature is described by
+Schlechtendal ('Bot. Zeit.,' 1857, p. 880), in <i>Cytisus nigricans</i>, and
+M. Moquin-Tandon describes an instance in the vine in one flower of
+which sepals, petals, stamens, and ovary were abortive, while the
+receptacle was hypertrophied and fasciated, and bore on its surface a
+few adventitious buds.<a name="FNanchor_11_11" id="FNanchor_11_11"></a><a href="#Footnote_11_11" class="fnanchor">[11]</a> The pedicels of <i>Streptocarpus Rexii</i> have
+also been observed in a fasciated state.<a name="FNanchor_12_12" id="FNanchor_12_12"></a><a href="#Footnote_12_12" class="fnanchor">[12]</a></p>
+
+<p>It has been occasionally observed that the fasciated condition is
+hereditary; thus, Moquin relates that some seeds of a fasciated
+<i>Cirsium</i> reproduced the same condition in the seedlings,<a name="FNanchor_13_13" id="FNanchor_13_13"></a><a href="#Footnote_13_13" class="fnanchor">[13]</a> while a
+similar tendency is inherited in the case of the cockscomb (<i>Celosia</i>).</p>
+
+<p>With reference to the nature of the deformity in question there is a
+difference of opinion; while most authors consider it to be due to the
+causes before mentioned, Moquin was of opinion that fasciation was due
+to a flattening of a single stem or branch. Linn&aelig;us, on the other hand,
+considered such stems to be the result of the formation of an unusual
+number of buds, the shoots resulting from which became coherent as
+growth proceeded:&mdash;"<i>Fasciata dici solet planta cum plures caules
+connascuntur, ut unus ex plurimis instar fasci&aelig; evadat<span class='pagenum'><a name="Page_16" id="Page_16">[Pg 16]</a></span> et compressus</i>"
+(Linn., 'Phil. Bot.,' 274). A similar opinion was held by J. D. Major in
+a singular book entitled 'De Plant&acirc;, Monstrosa, Gottorpiensi,'
+Schleswig, 1665, wherein the stem of a <i>Chrysanthemum</i> is depicted in
+the fasciated condition.</p>

+</div>
+
+<p>The stri&aelig;, which these stems almost invariably present, exhibit the
+lines of junction, and the spiral or other curvatures and contraction,
+which are so often met with, may be accounted for by the unequal growth
+of one portion of the stem as contrasted with that of another. Against
+this view Moquin cites the instances of one-stemmed plants, such as
+<i>Androsace maxima</i>, but, on the other hand, those herbaceous plants
+having usually but a single stem not unfrequently produce several which
+may remain distinct, but not uncommonly become united together. Prof.
+Hincks<a name="FNanchor_14_14" id="FNanchor_14_14"></a><a href="#Footnote_14_14" class="fnanchor">[14]</a> cites cases of this kind<span class='pagenum'><a name="Page_17" id="Page_17">[Pg 17]</a></span> in <i>Primula vulgaris</i>, <i>Hieracium
+aureum</i>, and <i>Ranunculus bulbosus</i>. I have myself met with several cases
+of the kind in <i>Primula veris</i>, in the Polyanthus, in the Daisy, and in
+the <i>Leontodon Taraxacum</i>, in which latter a fusion of two or more
+flower-stems bearing at the top a composite flower, and made up of two,
+three, four, or more flowers combined together, and containing all the
+organs that would be present in the same flowers if separate, is very
+common.</p>
+
+<p>Moquin's second objection is founded upon the fact that, in certain
+fasciated stems, the branches are not increased in number or altered in
+arrangement from what is usual; but however true this may be in
+particular cases, it is quite certain that in the majority of instances
+a large increase in the number of leaves and buds is a prominent
+characteristic of fasciated stems.</p>
+
+<p>Another argument used by the distinguished French botanist to show that
+fasciated stems are not due to cohesion of two or more stems, is founded
+on the fact that a transverse section of a fasciated stem generally
+shows an elliptical outline with but a single central canal. On the
+other hand, if two branches become united and a transverse section be
+made, the form of the cut surface would be more or less like that of the
+figure 8[symbol: 8 turned 90&deg;], although in old stems this may give
+place to an elliptical outline, but even then traces of two medullary
+canals may be found. This argument is very deceptive, for the appearance
+of the transverse section must depend, not only on the intimacy of their
+union, but also on the internal structure of the stems themselves. When
+two flowers cohere without much pressure they exhibit uniting circles
+somewhat resembling the figure of 8[symbol: 8 turned 90&deg;], but when more
+completely combined they have an outline of a very elongated figure, and
+something similar is to be expected in herbaceous stems. Even the
+elongated pith of a transversely cut, woody, fasciated stem only marks
+the intimate union of several branches, and Prof. Hincks, whose views
+the writer entirely shares, has noticed<span class='pagenum'><a name="Page_18" id="Page_18">[Pg 18]</a></span> instances of the union of two,
+and of only two, stems where the internal appearance was the same as in
+other fasciations.</p>
+
+<p>Moquin, moreover, raises the objection that it is unlikely that several
+branches should become united lengthwise in one plane only, and,
+further, that in the greater number of fasciations all the other
+branches which should be present are to be found&mdash;not one is wanting,
+not one has disappeared, as might have been anticipated had fusion taken
+place. In raising this objection, Moquin seems not sufficiently to have
+considered the circumstance that the buds in these cases are in one
+plane from the first, and are all about equal in point of age and size.</p>
+
+<p>The last objection that Moquin raises to the opinion that fasciation is
+the result of a grafting process is, that in such a case, examples
+should be found wherein the branches are incompletely fused, and where
+on a transverse section traces of the medullary canals belonging to each
+branch should be visible. The arrangement of leaves or buds on the
+surface should also in such a case indicate a fusion of several spiral
+cycles or whorls. To this it may be replied that such cases are met with
+very frequently indeed. A figure is given by De Candolle<a name="FNanchor_15_15" id="FNanchor_15_15"></a><a href="#Footnote_15_15" class="fnanchor">[15]</a> of a stem
+of <i>Spartium junceum</i> having several branches only imperfectly
+fasciated.</p>
+
+<p>Fasciated stems, then, seem to be best explained, as is stated by Prof.
+Hincks, "on the principle of adhesion arising in cases where from
+superabundant nourishment, especially if accompanied by some check or
+injury, numerous buds have been produced in close proximity, and the
+supposition that these growths are produced by the dilatation of a
+single stem is founded on a false analogy between fasciated stems and
+certain other anomalous growths."</p>
+
+<p>It will not, of course, be forgotten that this fasciated condition
+occurs so frequently in some plants as almost to constitute their
+natural state, <i>e.g.</i> <i>Sedum cristatum</i>,<span class='pagenum'><a name="Page_19" id="Page_19">[Pg 19]</a></span> <i>Celosia</i>, &amp;c. This condition
+may be induced by the art of the gardener&mdash;"<i>Fit idem arte, si plures
+caules enascentes cogantur penetrare coarctatum spatium et parturiri
+tanquam ex angusto utero, sic s&aelig;pe in Ranunculo, Beta, Asparago,
+Hesperide Pinu, Celosi&acirc;, Tragopogone, Scorzoner&acirc; Cotula f&oelig;tida</i>,"
+Linn&aelig;us op. cit.</p>
+
+<p>Plot, in his 'History of Oxfordshire,' considers fasciation to arise
+from the ascent of too much nourishment for one stalk and not enough for
+two, "which accident of plants," says Plot, the German virtuosi ('Misc.
+Curios. Med. Physic. Acad. Nat. Cur.,' Ann. i, Observ. 102,) "think only
+to happen after hard and late winters, by reason whereof, indeed, the
+sap, being restrained somewhat longer than ordinary, upon sudden thaws
+may probably be sent up more forcibly, and so produce these fasciated
+stalks, whereas the natural and graduated ascent would have produced
+them but single." Prof. Hincks' explanation is, however, more near to
+the truth, and his opinion is borne out by the frequency with which this
+change is met with in certain plants which are frequently forced on
+during their growth, as lettuce, asparagus, endive, &amp;c., all of which
+are very subject to this change. In the 'Transactions of the
+Horticultural Society of London,' vol. iv, p. 321, Mr. Knight gives an
+account of the cultivation of the cockscomb, so as to ensure the
+production of the very large flower-stalks for which this plant is
+admired. The principal points in the culture were the application of a
+large quantity of stimulating manure and the maintenance of a high
+temperature. One of them so grown measured eighteen inches in width.</p>
+
+<p>The list which is appended is intended to show those plants in which
+fasciation has been most frequently observed. It makes no pretension to
+be complete, but is sufficiently so for the purpose indicated: the *
+denotes the especial frequency of the change in question; the !
+indicates that the writer has himself seen the plant, so marked,
+affected in this way. The remainder have been copied from various
+sources.</p><p><span class='pagenum'><a name="Page_20" id="Page_20">[Pg 20]</a></span></p>

+<p><b>Cohesion of foliar organs.</b>&mdash;This takes place in several ways, and in
+very various degrees; the simplest case is that characterised by the
+cohesion of the margins of the same organ, as in the condition called
+perfoliate in descriptive works, and which is due either to a cohesion
+of the margins of the basal lobes of the leaf, or to the development of
+the leaf in a sheathing or tubular manner. As an abnormal occurrence, I
+have met with this perfoliation in a leaf of <i>Goodenia ovata</i>. The
+condition in question is often loosely confounded with connation, or the
+union of two leaves by their bases. In other cases the union takes place
+between the margins of two or more leaves.</p>
+
+
+
+<p><b>Cohesion of margins of single organs.</b>&mdash;The leaves of Hazels may often be
+found with their margins coherent at the<span class='pagenum'><a name="Page_22" id="Page_22">[Pg 22]</a></span> base, so as to become peltate,
+while in other cases, the disc of the leaf is so depressed that a true
+pitcher is formed. This happens also in the Lime <i>Tilia</i>, in which genus
+pitcher- or hood-like leaves (<i>folia cucullata</i>) may frequently be met
+with. There are trees with leaves of this character in the cemetery of a
+Cistercian Monastery at Sedlitz, on which it is said that certain monks
+were once hung: hence the legend has arisen, that the peculiar form of
+the leaf was given in order to perpetuate the memory of the martyred
+monks. ('Bayer. Monogr. <i>Tili&aelig;</i>,' Berlin, 1861.) It is also stated that
+this condition is not perpetuated by grafting.</p>

+</div>
+
+<p>I have in my possession a leaf of <i>Antirrhinum majus</i>, and also a
+specimen of <i>Pelargonium</i>, wherein the blade of the leaf is funnel-like,
+and the petiole is cylindrical, not compressed, and grooved on the upper
+surface, as is usually the case. A comparison of the leaves of
+<i>Pelargonium peltatum</i> with those of <i>P. cucullatum</i> ('Cav.<span class='pagenum'><a name="Page_23" id="Page_23">[Pg 23]</a></span> Diss.,'
+tab., 106) will show how easy the passage is from a peltate to a tubular
+leaf. In these cases the tubular form may rather be due to dilatation
+than to cohesion. M. Kickx<a name="FNanchor_16_16" id="FNanchor_16_16"></a><a href="#Footnote_16_16" class="fnanchor">[16]</a> mentions an instance of the kind in the
+leaves of a species of <i>Nicotiana</i>, and also figures the leaf of a rose
+in which two opposite leaflets presented themselves in the form of
+stalked cups. Schlechtendal<a name="FNanchor_17_17" id="FNanchor_17_17"></a><a href="#Footnote_17_17" class="fnanchor">[17]</a> notices something of the same kind in
+the leaf of <i>Amorpha fruticosa</i>; Treviranus<a name="FNanchor_18_18" id="FNanchor_18_18"></a><a href="#Footnote_18_18" class="fnanchor">[18]</a> in that of <i>Aristolochia
+Sipho</i>.</p>
+
+<p>M. Puel<a name="FNanchor_19_19" id="FNanchor_19_19"></a><a href="#Footnote_19_19" class="fnanchor">[19]</a> describes a leaf of <i>Polygonatum multiflorum</i>, the margins
+of which were so completely united together, as only to leave a circular
+aperture at the top, through which passed the ends of the leaves. The
+Rev. Mr. Hincks, at the meeting of the British Association at Newcastle
+(1838), showed a leaf of a Tulip, whose margins were so united that the
+whole leaf served as a hood, and was carried upwards by the growing
+flower like the calyptra of a Moss.</p>
+
+<p>The margins of the stipules are also occasionally united, so as to form
+a little horn-shaped tube. I have met with instances of this kind in the
+common white clover, <i>Trifolium repens</i>, where on each side of the base
+of the petiole the stipules had the form just indicated. That the bracts
+also may assume this condition, may be inferred from the peculiar
+horn-like structures of <i>Marcgraavia</i>, which appear to originate from
+the union of the margins of the reflected leaf.</p>
+
+<p><b>Tubular petals</b> occur normally in some flowers, as <i>Helleborus</i>,
+<i>Epimedium</i>, <i>Viola</i>, &amp;c., and as an exceptional occurrence I have seen
+them in <i>Ranunculus repens</i>, while in <i>Eranthis hyemalis</i> transitions
+may frequently be seen between the flat outer segments of the perianth
+and the tubular petals. To Dr. Sankey, of Sandywell Park, I am indebted
+for the flower of a Pelargonium,<span class='pagenum'><a name="Page_24" id="Page_24">[Pg 24]</a></span> in which one of the petals had the
+form of a cup supported on a long stalk. This cup-shaped organ was
+placed at the back of the flower, and had the dark colour proper to the
+petals in that situation. I have seen a petal of Clarkia similarly
+tubular, while some of the cultivated varieties of <i>Primula sinensis</i>
+exhibit tubular petals so perfect in shape as closely to resemble
+perfect corollas.</p>

+
+<p>Like the petals, the stamens, and even the styles, assume a hollow
+tubular form. This change of form in the case of the stamens is, of
+course, usually attended by the petaloid expansion of the filament, or
+anther, and the more or less complete obliteration of the pollen sacs,
+as in Fuchsias, and in some double-flowered Antirrhinums.<a name="FNanchor_20_20" id="FNanchor_20_20"></a><a href="#Footnote_20_20" class="fnanchor">[20]</a> So also in

+in other organs, it hardly seems worth while to adopt a special term for
+the phenomenon, as it presents itself in one set of organs.</p>
+
+<p>In many of these cases it is difficult to say whether the cup-like or
+tubular form is due to a dilatation or hollowing out of the organ
+affected, or to a fusion of its edges. The arrangement of the veins will
+in some<span class='pagenum'><a name="Page_25" id="Page_25">[Pg 25]</a></span> cases supply the clue, and in others the regularity of form
+will indicate the nature of the malformation, for in those instances
+where the cup is the result of expansion, its margin is more likely to
+be regular and even than in those where the hollow form is the result of
+fusion.</p>
+
+
+
+<p><b>Cohesion of several organs by their margins:&mdash;leaves, &amp;c.</b>&mdash;The union of
+the margins of two or more different organs is of more common occurrence
+than the preceding, the leaves being frequently subjected to this
+change. Occasionally, the leaflets of a compound leaf have been observed
+united by their margins, as in the strawberry, the white trefoil, and
+others. Sometimes the union takes place by means of the stalks only. I
+have an instance of this in a Pelargonium, in <i>Trop&aelig;olum majus</i>, and
+<i>Strelitzia regina</i>; in other cases, the whole extent of the leaf
+becomes joined to its neighbour, the leaves thus becoming completely
+united by their edges, as in those of <i>Justicia</i>, <i>oxyphylla</i>.<a name="FNanchor_22_22" id="FNanchor_22_22"></a><a href="#Footnote_22_22" class="fnanchor">[22]</a> M.
+Clos<a name="FNanchor_23_23" id="FNanchor_23_23"></a><a href="#Footnote_23_23" class="fnanchor">[23]</a> has observed the same thing in the leaves of the lentil <i>Ervum
+lens</i>, conjoined with fasciation of the stem, and many other examples
+might be given. Some of the recorded cases are probably really due to
+fission of one leaf into two rather than to fusion. Although usually the
+lower portions of the leaf are united together, leaving the upper parts
+more or less detached, there are some instances in which the margins of
+the leaf at their upper portion have been noticed to be coherent, while
+their lower portions, with their stalks, were completely free.<a name="FNanchor_24_24" id="FNanchor_24_24"></a><a href="#Footnote_24_24" class="fnanchor">[24]</a></p>
+
+<p>Cohesion of the leaves frequently accompanies the union of the branches
+and fasciation as might have been anticipated. Moquin cites the
+fenestrated leaves of <i>Dracontium pertusum</i>, as well as some cases of a
+similar kind that are occasionally met with, as instances<span class='pagenum'><a name="Page_26" id="Page_26">[Pg 26]</a></span> of the
+cohesion of the margins at the base and apex of the leaf, which thus
+appears perforated. This appearance, however, is probably due to some
+other cause. When the leaves are verticillate and numerous, and they
+become coherent by their margins, they form a foliaceous tube around the
+stem. When there are but two opposite leaves, and these become united by
+their margins, we have a state of things precisely resembling that to
+which the term connate is applied.</p>
+
+<p>Fusion of the edges of the cotyledons also occasionally takes place, as
+in <i>Ebenus cretica</i>.<a name="FNanchor_25_25" id="FNanchor_25_25"></a><a href="#Footnote_25_25" class="fnanchor">[25]</a> It has also been observed in <i>Tithonia</i>, and is
+of constant occurrence in the seed leaves of some <i>Mesembryanthema</i>.
+This condition must be carefully distinguished from the very similar
+appearance produced by quite a different cause, viz., the splitting of
+one cotyledon into two, which gives rise to the appearance as if two
+were partially united together.</p>
+
+<p>Some of the ascidia or pitcher-like formations are due to the cohesion
+of the margins of two leaves, as in a specimen of <i>Crassula
+arborescens</i>, observed by C. Morren.</p>

+
+<p>The stipules may also be fused together in different<span class='pagenum'><a name="Page_27" id="Page_27">[Pg 27]</a></span> ways; their edges
+sometimes cohere between the leaf and the stem, and thus form a solitary
+intra-axillary stipule. At other times they become united in such a
+manner as to produce a single notched stipule opposite to the leaf.
+Again, in other cases, they are so united on each side of the stem, that
+in place of four there seem only to exist two, common to the two leaves
+as in the Hop.</p>
+
+<p>To the Rev. M. J. Berkeley I am indebted for specimens of a curious
+pitcher-like formation in the garden Pea. The structure in question
+consisted of a stalked foliaceous cup proceeding from the inflorescence.
+On examination of the ordinary inflorescence, there will be seen at the
+base of the upper of two flowers a small rudimentary bract, having a
+swollen circular or ring-like base, from which proceeds a small
+awl-shaped process, representing the midrib of an abortive leaf. In some
+of Mr. Berkeley's specimens, the stipules were developed as leafy
+appendages at the base of the leaf-stalk or midrib, the latter retaining
+its shortened form, while, in others, the two stipules had become
+connate into a cup, and all trace of the midrib was lost. The cup in
+question would thus seem to have been formed from the connation of two
+stipules which are ordinarily abortive.</p>
+
+<p>Cohesion of the bracts by their edges, so as to form a tubular
+involucre, or by their surfaces, so as to form a cupule, is not of
+uncommon occurrence, under natural conditions, and may be met with in
+plants which ordinarily do not exhibit this appearance.</p>
+
+
+
+<p><b>Cohesion of the sepals</b> in a normally polypetalous calyx renders the
+latter gamosepalous, and is not of uncommon occurrence, to a partial
+extent, though rarely met with complete. I have observed a junction of
+the sepals to be one of the commonest malformations among Orchids,
+indeed such a state of things occurs normally in <i>Masdevallia
+Cypripedium</i>, &amp;c. An illustration of this occurrence is given by Mr. J.
+T. Moggridge in <i>Ophrys insectifera</i>, in 'Seemann's Journal<span class='pagenum'><a name="Page_28" id="Page_28">[Pg 28]</a></span> of Botany,'
+1866, p. 168, tab. 47. In Orchids, this cohesion of sepals is very often
+co-existent with other more important changes, such as absence of the
+labellum, dislocation of the parts of the flower, &amp;c.</p>

+were united into a long tube, their upper portions were free and bent
+downwards, forming a sort of irregular limb. An instance of the
+polypetalous regular perianth of <i>Clematis viticella</i> being changed into
+a monopetalous irregular one, like the corolla of Labiates, is recorded
+by Jaeger.<a name="FNanchor_27_27" id="FNanchor_27_27"></a><a href="#Footnote_27_27" class="fnanchor">[27]</a> There is in cultivation a variety of <i>Papaver
+bracteatum</i>, in which the petals are united by their margins so as to
+form a large cup. Under<span class='pagenum'><a name="Page_29" id="Page_29">[Pg 29]</a></span> normal circumstances, the petals become fused
+together by their edges along their whole extent, at the base only, at
+the apex only, as in the Vine, or at the base and apex, leaving the
+central portions detached. Indications of the junction of the petals may
+generally be traced by the arrangement of the veins, or by the notches
+or lobes left by imperfect union. In Crocuses I have frequently met with
+cohesion of the segments of the perianth, by means of their surfaces,
+but the union was confined to the centre of the segment, leaving the
+rest of the surfaces free.</p>
+
+
+
+<p><b>Cohesion of the stamens.</b>&mdash;Under natural circumstances, cohesion of the
+stamens is said to take place either by the union of their filaments, so
+as to form one, two, or more parcels (Monadelphia, Diadelphia,
+Polyadelphia); at other times, by the cohesion of the anthers
+(Syngenesia), in which latter case the union is generally very slight.
+It must be remembered, however, that the so-called cohesion of the
+filaments is in many cases due rather to the formation of compound
+stamens, <i>i.e.</i> to the formation from one original staminal tubercle of
+numerous secondary ones, so that the process is rather one of over
+development than of fusion or of disjunction. These conditions may be
+met with as accidental occurrences in plants or in flowers, not usually
+showing this arrangement. Thus, for instance, Professor Andersson, of
+Stockholm, describes a monstrosity of <i>Salix calyculata</i>, in which the
+stamens were so united together as to form a tube open at the top like a
+follicle.<a name="FNanchor_28_28" id="FNanchor_28_28"></a><a href="#Footnote_28_28" class="fnanchor">[28]</a> This is an exaggerated degree of that fusion which exists
+normally in <i>Salix monandra</i>, in Cucurbits and other plants.</p>
+

+
+ADHESION.</h4>
+
+
+<p>Adhesion, so called, occurs either from actual union of originally
+distinct members of different whorls or from the non-occurrence of that
+separation which usually takes place between them. It is thus in some
+degree a graver deviation than cohesion, and is generally a consequence
+of, or at least is coexistent with, more serious changes; thus if two
+leaves of the same whorl are coherent the change is not very great, but
+if two leaves belonging to different whorls, or two leaves in the same
+spiral cycle are adherent, a deformation in the axis or a certain amount
+of dislocation must almost necessarily exist. Adhesion as a normal
+occurrence is usually the result of a lack of separation rather than of
+union of parts primitively separate. Instances of adhesion between
+different organs is seen under ordinary circumstances in the bract of
+the Lime tree, which adheres to the peduncle, also in <i>Neuropeltis</i>,
+while in <i>Erythrochiton hypophyllanthus</i> the cymose peduncles are
+adherent to the under surface of the leaf.</p>
+
+<p>Adhesion between the axes of the same plant is sufficiently treated of
+under the head of Cohesion, from which it is in this instance impossible
+to make a distinction. Adhesion of the inflorescence is necessarily a
+frequent accompaniment of fasciation and cohesion of the branches.</p>
+
+
+
+<p><b>Adhesion of foliar organs</b> may occur either between the margins or
+between the surfaces of the affected parts; in the former case there is
+almost necessarily more or less displacement and change of direction,
+such as a twisting of the stem and a vertical rather than a horizontal
+attachment of the foliar organ to it; hence<span class='pagenum'><a name="Page_33" id="Page_33">[Pg 33]</a></span> it generally forms but a
+part of other and more important deviations.</p>
+
+
+
+<p><b>Adhesion of leaves by their surfaces.</b>&mdash;The union of leaves by their
+surfaces is not of very frequent occurrence, many of the instances cited
+being truly referable to other conditions. Bonnet describes the union of
+two lettuce leaves, and Turpin that of two leaves of <i>Agave americana</i>,
+in which latter the upper surface of one leaf was adherent to the lower
+surface of the leaf next above it, and I have myself met with similar
+instances in the wallflower and in lettuce and cabbage leaves; other
+instances have been mentioned in <i>Saxifraga</i>, <i>Gesnera</i>, <i>&amp;c.</i><a name="FNanchor_30_30" id="FNanchor_30_30"></a><a href="#Footnote_30_30" class="fnanchor">[30]</a></p>
+
+<p>In these cases, owing to the non-development of the internodes, the
+nascent leaves are closely packed, and the conditions for adhesion are
+favorable, but in most of the so-called cases of adhesion of leaf to
+leaf by the surface, a preferable explanation is afforded either by an
+exuberant development (hypertrophy) or by chorisis (see sections on
+those subjects). Thus, when a leaf of this kind is apparently so united,
+that the lower surface of one is adherent to the corresponding surface
+of another, the phenomenon is probably due rather to extra development
+or to fission. There is an exception to this, however, in the case of
+two vertically-erect leaves on opposite sides of the stem; here the two
+upper or inner surfaces may become adherent, as in an orange, where two
+leaves were thus united, the terminal bud between them being suppressed
+or abortive.</p>
+
+<p>Adhesion between the membranous bract of <i>Narcissus poeticus</i> and the
+upper surface of the leaf is described by Moquin.<a name="FNanchor_31_31" id="FNanchor_31_31"></a><a href="#Footnote_31_31" class="fnanchor">[31]</a> The same author
+mentions having seen a remarkable example of adhesion in the involucels
+of <i>Caucalis leptophylla</i>, the bracts of which were soldered to the
+outer surface of the flowers. M. Bureau<a name="FNanchor_32_32" id="FNanchor_32_32"></a><a href="#Footnote_32_32" class="fnanchor">[32]</a> mentions<span class='pagenum'><a name="Page_34" id="Page_34">[Pg 34]</a></span> an instance
+wherein the spathe of <i>Narcissus biflorus</i> was partially twisted in such
+a manner that the lower surface of its median nerve was adherent to the
+corresponding surface of one of the sepals, mid-rib to mid-rib, thus
+apparently confirming a law of G. de Hilaire, that when two parts of the
+same individual unite, they generally do so by the corresponding
+surfaces or edges, but the rule is probably not so general in its
+application as has been supposed.</p>
+
+
+
+<p><b>Adhesion of foliar to axile organs.</b>&mdash;The appendicular organs may
+likewise be found united to the axile ones. This union takes place in
+many ways; sometimes the leaves do not become detached from the stem for
+a considerable distance, as in the so-called decurrent leaves, at other
+times the leaves are prolonged at their base into lobes, which are
+directed along the stem, and are united with it. Turpin records a
+tendril of a vine which was fused with the stem for some distance, and
+bore leaves and other tendrils. Union of the leaf or bract with the
+flower-stalk is not uncommon. It occurs normally in the Lime and other
+plants.</p>
+
+

+Adhesion of the petals to the column is not of infrequent<span class='pagenum'><a name="Page_35" id="Page_35">[Pg 35]</a></span> occurrence
+among Orchids. I have observed cases of the adhesion of the segments of

+occasionally met with, present a very singular appearance, owing to the
+adhesion of the stamens to the outer segments of the perianth, the
+former, moreover, being partially petaloid in aspect. M. de la Vaud<a name="FNanchor_35_35" id="FNanchor_35_35"></a><a href="#Footnote_35_35" class="fnanchor">[35]</a>

+malformation of <i>Fuchsia</i> wherein the petals were so completely adherent
+to the stamens, that the former were dragged out of their ordinary

+complete that, no trace of it could be seen externally. It should be

+
+<p>It is curious to notice how very rare it is for the calyx to adhere to
+the ovary in flowers where that organ is normally superior. The "<i>calyx
+inferus</i>" seems scarcely ever to become "<i>calyx superus</i>," while, on the
+other hand, the "<i>calyx normaliter superus</i>" frequently becomes inferior
+from detachment from, or from want of union with the surface of the
+ovary.</p>
+

+
+<p><b>Adhesion of fruit to branch.</b>&mdash;Of this Mr. Berkeley<a name="FNanchor_40_40" id="FNanchor_40_40"></a><a href="#Footnote_40_40" class="fnanchor">[40]</a> cites an instance
+in a vegetable marrow (<i>Cucumis</i>), where a female flower had become
+confluent with the branch, at whose base it was placed, and also with
+two or more flowers at the upper part of the same branch, so as to make
+an oblique scar running down from the apex of the fruit to the branch.</p>
+
+
+
+<p><b>Synanthy.</b>&mdash;Adhesion of two or more flowers takes place in various ways;
+sometimes merely the stalks<span class='pagenum'><a name="Page_37" id="Page_37">[Pg 37]</a></span> are united together, so that we have a
+single peduncle, bearing at its extremity two flowers placed in
+approximation very slightly adherent one to the other. In this manner I
+have seen three flowers of the vegetable marrow on a common stalk, the
+flowers themselves being only united at the extreme base. Occasionally
+cases may be met with wherein the pedicels of a stalked flower become
+adherent to the side of a sessile flower. I have noticed this commonly
+in <i>Umbellifer&aelig;</i>. Union of this kind occurs frequently in the common
+cornel (<i>Cornus</i>), wherein one of the lower flowers becomes adherent to
+one of the upper ones. In De Candolle's 'Organographie V&eacute;g&eacute;tale,' Plates
+14 and 15, are figured cases of fusion of the flower stems of the
+Hyacinth and of a <i>Centaurea</i>. In other cases the union involves not
+only the stalk but the flowers themselves; thus fusion of the flowers is
+a common accompaniment of fasciation, as was the case in the <i>Campanula</i>
+figured in the cut (fig. 14).</p>

+</div>
+
+<p>Synanthy may take place without much derangement of the structure of
+either flower, or the union may be attended with abortion or suppression
+of some of the<span class='pagenum'><a name="Page_38" id="Page_38">[Pg 38]</a></span> parts of one or both flowers. Occasionally this union is
+carried to such an extent that a bloom appears to be single, when it is,
+in reality, composed of two or more, the parts of which have become not
+only fused, but, as it were, thrust into and completely incorporated one
+with another, and in such a manner as to occupy the place of some parts
+of the flower which have been suppressed. It must not be overlooked that
+this adhesion of one flower to another is a very common occurrence under
+natural circumstances, as in <i>Lonicera</i>, in the common tomato, in
+<i>Pomax</i>, <i>Opercularia</i>, <i>Symphyomyrtus</i>, &amp;c., while the large size of
+some of the cultivated sunflowers is in like manner due to the union of
+two or more flower-heads.</p>
+
+<p>One of the simplest instances of synanthy is that mentioned by M.
+Duchartre,<a name="FNanchor_41_41" id="FNanchor_41_41"></a><a href="#Footnote_41_41" class="fnanchor">[41]</a> in which two flowers of a hyacinth were united together
+simply by means of two segments of the perianth one from each flower. A
+similar occurrence has been cited by M. Gay in <i>Narcissus chrysanthus</i>.
+In like manner the blossoms of Fuchsias or Loniceras occasionally become
+adherent merely by their surface, without involving any other change in
+the conformation of the flowers. M. Maugin alludes to a case of this
+kind in <i>Aristolochia Clematitis</i>.<a name="FNanchor_42_42" id="FNanchor_42_42"></a><a href="#Footnote_42_42" class="fnanchor">[42]</a></p>
+
+<p>But it is more usual for some of the organs to be suppressed, so that
+the number of existing parts is less than would be the case in two or
+more uncombined flowers. A few illustrations will exemplify this. In two
+flowers of <i>Matthiola incana</i>, that I observed to be joined together,
+there were eight sepals, eight petals, and ten perfect stamens, eight
+long and two short, instead of twelve. Closer examination showed that
+the point of union between the two flowers occurred just where, under
+ordinary circumstances, the two short stamens would be. In this instance
+but little suppression had occurred. In similar flowers of <i>Narcissus
+incomparabilis</i> I remarked a ten-parted perianth,<span class='pagenum'><a name="Page_39" id="Page_39">[Pg 39]</a></span> ten stamens within a
+single cup, two styles, and a five-celled ovary. Here, then, it would
+appear that two segments of the perianth, two stamens, and one carpel
+were suppressed. In a Polyanthus there were nine sepals, nine petals,
+nine stamens, and a double ovary.</p>

+
+<p>As an illustration of a more complicated nature reference may be made to
+three flowers of <i>Aconitum Napellus</i>, figured by A. de Chamisso,
+'Linn&aelig;a,' vol. vii, 1832, p. 205, tab. vii, figs. 1, 2. In this specimen
+the two outer blossoms had each four sepals present, namely, the upper
+hooded one, one of the lateral sepals, and both of the inferior ones;
+the central flower had only the upper sepal and one other, probably one
+of the lower sepals; thus there were but ten sepals instead of fifteen.
+The nectary-like petals, the stamens, and pistils were all present in
+the lateral flowers, but were completely suppressed in the middle one. A
+less degree of suppression was exemplified in a triple flower of
+<i>Calanthe vestita</i> sent me by Dr. Moore, of Glasnevin, in which all the
+parts usually existing in<span class='pagenum'><a name="Page_40" id="Page_40">[Pg 40]</a></span> three separate flowers were to be found, with
+the exception of the spur belonging to the labellum of the middle flower
+(figs. 15, 16).</p>
+
+<p>One of the most common malformations in the Foxglove (<i>Digitalis</i>)
+results from the fusion of several of the terminal flowers into one. In
+these cases the number of parts is very variable in different instances;
+the sepals are more or less blended together, and the corollas as well
+as the stamens are usually free and distinct, the latter often of equal
+length, so that the blossom, although truly complex, is, as to its
+external form, less irregular than under natural circumstances. The
+centre of these flowers is occupied by a two to five-celled pistil,
+between the carpels of which, not unfrequently, the stem of the plant
+projects, bearing on its sides bracts and rudimentary flowers. (See
+Prolification.) An instance of this nature is figured in the 'Gardeners'
+Chronicle,' 1850, p. 435, from which the cut (fig. 17) is borrowed.</p>

+<p class="caption"> <span class="smcap">Fig.</span> 17.&mdash;Synanthy and other changes in a Foxglove.</p>
+</div>
+
+<p>One of the most singular recorded instances of changes connected with
+fusion of the flowers is that<span class='pagenum'><a name="Page_41" id="Page_41">[Pg 41]</a></span> cited by Reinsch,<a name="FNanchor_43_43" id="FNanchor_43_43"></a><a href="#Footnote_43_43" class="fnanchor">[43]</a> where two female
+flowers of <i>Salix cinerea</i> were so united with a male one as to produce
+an hermaphrodite blossom.</p>
+
+<p>It follows, from what has been said, that the number of parts that are
+met with in these fused flowers varies according to the number of
+blossoms and of the organs which have been suppressed. Comparatively
+rarely do we find all the organs present; but when two flowers are
+united together we find every possible variety between the number of
+parts naturally belonging to the two flowers and that belonging to a
+single one. Sometimes instances are met with wherein the calyx does not
+present the normal number of parts, while the other parts of the flower
+are in excess. I have seen in a <i>Calceolaria</i> a single calyx, with the
+ordinary number of sepals, enclosing two corollas, adherent simply by
+their upper lips, and containing stamens and pistils in the usual way.
+In this instance, then, the sepals of one flower must have been
+suppressed, while no such suppression took place in the other parts of
+the flower.</p>
+
+<p>Professor Charles Morren paid special attention to the various methods
+in which the flowers of Calceolarias may become fused, and to the
+complications that ensue from the suppression of some parts, the
+complete amalgamation of others, &amp;c. Referring the reader to the Belgian
+savant's papers for the full details of the changes observed, it is only
+necessary to allude to a few of the most salient features.</p>
+
+<div class="center">

+<p class="caption"> <span class="smcap">Fig.</span> 18.&mdash;Synanthic flowers of Calceolaria in which, with two upper lips, there was but a single lower one.</p>
+</div>
+
+<p>Sometimes the upper lips of two flowers are fused into one, the two
+lower remaining distinct. In other cases, the upper lip disappears
+altogether, while there are two lower lips placed opposite one another;,
+of the stamens, sometimes<span class='pagenum'><a name="Page_42" id="Page_42">[Pg 42]</a></span> the outermost, at other times the innermost
+disappear.<a name="FNanchor_44_44" id="FNanchor_44_44"></a><a href="#Footnote_44_44" class="fnanchor">[44]</a></p>
+
+<p>Occasionally there appears to be, as it were, a transference of the
+parts of one flower to another. One of the simplest and most
+intelligible cases of this kind is recorded by Wigand in the 'Flora' for
+1856, in a compound flower of <i>Polygonatum anceps</i>, in which within a
+twelve-parted perianth there were twelve stamens and two pistils, one
+four-celled, the other two-celled; hence it would appear as if a carpel
+belonging to one flower had become united to those constituting the
+pistil of the adjacent one. Among Orchids this fusion of some of the
+elements of different flowers, together with the suppression of others,
+is carried to such an extent as to render the real structure difficult
+to decipher. Sometimes flowers of <i>Ophrys aranifera</i>, at first sight
+seeming normal as to the number, and almost so as regards the
+arrangement of their parts, have yet, on examination, proved to be the
+result of a confluence of two flowers. Mr. Moggridge has observed
+similar phenomena in the same species at Mentone.</p>
+
+<p>Sometimes the fusion affects flowers belonging to different branches of
+the same inflorescence, as in <i>Centranthus ruber</i>, described by
+Buchenau, 'Flora,' 1857, p. 293, and even a blossom of one generation of
+axes may be united with a flower belonging to another generation. Thus
+M. Michalet<a name="FNanchor_45_45" id="FNanchor_45_45"></a><a href="#Footnote_45_45" class="fnanchor">[45]</a> speaks of a case wherein the terminal flower of
+<i>Betonica alopecuros</i> was affected with Peloria, and fused with an
+adjacent one belonging to a secondary axis of inflorescence, and not yet
+expanded. This latter flower had no calyx, but in its place were three
+bracts, surrounding the corolla; this again was united to the calyx of
+the terminal bloom in a most singular manner, the limb of the corolla
+and that of the calyx being so joined one to the other<span class='pagenum'><a name="Page_43" id="Page_43">[Pg 43]</a></span> as to form but a
+single tube. It is not uncommon, as has been before stated, to find two
+corollas enclosed within one calyx, but this is probably the only
+recorded instance of the fusion of the calyx and corolla of two
+different flowers belonging to two different axes.</p>
+
+<p>From the preceding details, as well as from others which it is not
+necessary to give in this place, it would appear that synanthy is more
+liable to occur where the flowers are naturally crowded together<a name="FNanchor_46_46" id="FNanchor_46_46"></a><a href="#Footnote_46_46" class="fnanchor">[46]</a>
+than where they are remote; so too, the upper or younger portions of the
+inflorescence are those most subject to this change. In like manner the
+derangements consequent on the coalescence of flowers are often more
+grave in the central organs, which are most exposed to pressure, and
+have the least opportunities of resisting the effects of that agency,
+than they are in the outer portions of the flowers where growth is less
+restricted.</p>
+
+<p>Morren in his papers on synanthic <i>Calceolarias</i>, before referred to,
+considers that the direction in which fusion acts is centripetal, <i>e.g.</i>
+from the circumference towards the centre of the flower, thus reversing
+the natural order of things. He considers that there is a radical
+antagonism between the normal organizing forces and the teratological
+disorganizing forces, and explains in this way the frequent sterility of
+monsters from an imperfect formation of stamens, or pistils, or both.</p>
+
+<p>The greater tendency in synanthic flowers of parts of one whorl to
+adhere to the corresponding organs in another flower has often been
+remarked, though the dislocation of parts may be so great as to prevent
+this from being carried out in all cases. It appears also that synanthy
+is more frequently met with among flowers which have an inferior ovary
+than in those in which the relative position of the organ in question<span class='pagenum'><a name="Page_44" id="Page_44">[Pg 44]</a></span>
+is reversed. This remark applies particularly to individual cases; the
+proportion as regards the genera may not be so large. The explanation of
+this must of course depend on the circumstances of each particular case;
+and it would be wrong to attempt to lay down a general rule, when
+organogenists have not yet fully decided in what plants the inferior
+ovary is an axial structure, and in what others the appearance is due to
+the adhesion of the base of the calyx to the carpels.</p>
+
+<p>The list which follows is not intended as a complete one, but it may
+serve to show what plants are more particularly subject to this anomaly;
+the * indicates unusual frequency of occurrence, the ! signifies that
+the writer has himself seen instances in the plants named. Many of the
+recorded cases of Synanthy are really cases of adhesion of the
+inflorescence rather than of the flowers.</p>

+<p><b>Syncarpy.</b>&mdash;In the preceding section it has been shown that the carpels,
+like other parts of the flower, are subject to be united together. This
+union may either take place between the carpels of a single flower or
+between the pistils of different flowers. In the latter case the other
+floral whorls are generally more or less altered. Where, however, the
+ovary is, as it is called, inferior, it may happen that the pistils of
+different flowers may coalesce more or less without much alteration in
+the other parts of the flower, as happens normally in many
+<i>Caprifoliace&aelig;</i>, <i>Rubiace&aelig;</i>, &amp;c. &amp;c. In some of these cases it must be
+remembered that the real structure of the apparent fruit is not made out
+beyond dispute, the main points of controversy being as to what, if any,
+share the dilated fruit-stalk or axis takes in the formation of such
+organs. Again, it will be borne in mind that in some cases the so-called
+fruit is made up of a number of flowers all fused together, as in the
+Mulberry or the Pineapple, in which plants what<span class='pagenum'><a name="Page_46" id="Page_46">[Pg 46]</a></span> is, in ordinary
+language, called the fruit really consists of the whole mass of flowers
+constituting the inflorescence fused together. Union of the fruits may
+also in some cases take place between the carpels after the fall of the
+other floral whorls, particularly when the outer layers of the pericarp
+assume a succulent condition, so that under the general head of syncarpy
+really different conditions are almost necessarily grouped together,
+and, in seeking to investigate the causes of the phenomenon, the
+particular circumstances of each individual case must be taken into
+account. Syncarpy takes place in various degrees; sometimes only the
+stalks are joined; at other times the whole extent of the fruit, as in
+cherries, &amp;c. This peculiarity did not escape the observant mind of
+Shakespeare&mdash;</p>

+
+<p>A similar union has been observed in peaches, gooseberries, gourds,
+melons, and a great many other fruits. In the Barbarossa grape I have
+frequently seen a fusion of two, three, four or more berries quite at
+the end of the bunch, so that the clusters were terminated by a compound
+grape. Seringe has remarked sometimes two, sometimes three, fruits of
+<i>Ranunculus tripartitus</i> soldered together. He has also seen three
+melons similarly joined.<a name="FNanchor_47_47" id="FNanchor_47_47"></a><a href="#Footnote_47_47" class="fnanchor">[47]</a> Turpin mentions having seen a complete
+union between the three smooth and leathery pericarps which are
+naturally separate and enclosed within the spiny cupule of the
+chestnut.<a name="FNanchor_48_48" id="FNanchor_48_48"></a><a href="#Footnote_48_48" class="fnanchor">[48]</a> Poiteau and Turpin have figured and described in their
+treatise on fruit trees, under the name of N&eacute;fle de Correa, four or five
+medlars, joined together and surmounted by all the persistent leaflets
+of the calyces.<a name="FNanchor_49_49" id="FNanchor_49_49"></a><a href="#Footnote_49_49" class="fnanchor">[49]</a></p>
+
+<p><span class='pagenum'><a name="Page_47" id="Page_47">[Pg 47]</a></span>A very remarkable example of Syncarpy has been recorded by E. K&oelig;nig
+in which nine strawberries were borne on one stem (<i>Fragaria
+botryformis</i>),<a name="FNanchor_50_50" id="FNanchor_50_50"></a><a href="#Footnote_50_50" class="fnanchor">[50]</a> and a similar malformation has been observed in the
+Pineapple.</p>
+
+<p>When two fruits are united together they may be of about equal size,
+while in other cases one of the two is much smaller than the other. This
+was the case in two cucumbers given to me by Mr. James Salter. These
+were united together along their whole length excepting at the very
+tips; the upper one of the two was much larger than the lower, and
+contained three cells, the lower fruit was one-celled by suppression.
+Both fruits were curved, the curvature being evidently due to the more
+rapid growth of the upper as compared with the lower one.</p>

+</div>
+
+<p>In many of these cases, where the fruits are united by their bases, the
+summits become separated one from the other, so as to resemble the
+letter V. Such divergence<span class='pagenum'><a name="Page_48" id="Page_48">[Pg 48]</a></span> is of frequent occurrence where fruits are
+united by their stalks, because, as growth goes on, the tendency must
+necessarily be towards separation and divergence of the tips of the
+fruit.</p>
+
+<p>In some cases of Syncarpy the fusion and interpenetration of the carpels
+is carried to such an extent that it is very difficult to trace on the
+outer surface the lines of union. The fruit in these cases resembles a
+single one of much larger size than usual. Moquin mentions a double
+apple in which the connection was so close that the fruit was not very
+different in form from what is customary, and a similar thing happens
+with the tomato. In the case of stone-fruits it sometimes happens, not
+only that the outer portions are adherent, but that the stones are so
+likewise.</p>
+
+<p>M. R&oelig;per has observed two apples grafted together, one of which had
+its stalk broken, and seemed evidently borne and nourished by the other
+apple;<a name="FNanchor_51_51" id="FNanchor_51_51"></a><a href="#Footnote_51_51" class="fnanchor">[51]</a> and a similar occurrence happens not infrequently in the
+cucumber. Moquin has seen three united cherries having only a single
+stalk jointed to the central fruit, the lateral cherries having each a
+slight depression or cicatrix marking the situation of the suppressed
+stalks. Schlotterbec has figured three apples presenting precisely
+similar appearances.<a name="FNanchor_52_52" id="FNanchor_52_52"></a><a href="#Footnote_52_52" class="fnanchor">[52]</a></p>
+
+<p>Fusion of two or more nuts (<i>Corylus</i>) is not uncommon; I have seen as
+many as five so united.<a name="FNanchor_53_53" id="FNanchor_53_53"></a><a href="#Footnote_53_53" class="fnanchor">[53]</a> In these cases the fruits may be united
+together in a ring or in linear series.</p>
+
+<p>In some <i>Leguminos&aelig;</i>, contrary to the general rule in the order, more
+than one carpel is found; thus peas, French beans, and other similar
+plants, are occasionally met with having two or more pods within the
+same calyx, and in <i>Gleditschia triacanthos</i> and <i>C&aelig;salpinia digyna</i>
+this is so commonly the case as to be considered almost the normal
+state. (De Cand. 'Mem.<span class='pagenum'><a name="Page_49" id="Page_49">[Pg 49]</a></span> Leg.,' pl. 2, fig. 6; pl. 3, fig. 2.) At times
+these carpels become fused together, and it becomes difficult, when the
+traces of the flower have disappeared, to ascertain whether these
+carpels were formed in one flower, or whether they were the result of
+the fusion of several blossoms. I have seen an instance of this kind in
+a plum in which there were two carpels in the same flower, the one being
+partially fused to the other. The nature of such cases may usually be
+determined by an inspection of the peduncle which shows no traces of
+fusion. (See chapter on Multiplication.)</p>
+
+<p>When, however, the fruits are sessile, and they become grafted together,
+the kind of syncarpy is difficult to distinguish. It, may, nevertheless,
+be said as a general rule that the union brought about by the
+approximation of two fruits, after the fall of the floral whorls, is
+never so complete or so intimate as that determined by synanthy; and
+also that in those cases where there are supernumerary carpels in the
+flower, and those carpels become united together, they are rarely so
+completely fused that their individuality is lost.</p>
+
+<p>An analogous phenomenon takes place not uncommonly in mosses, the spore
+capsules of which become united together in various ways and degrees.
+Schimper<a name="FNanchor_54_54" id="FNanchor_54_54"></a><a href="#Footnote_54_54" class="fnanchor">[54]</a> cites the following species as subject to this
+anomaly:&mdash;<i>Buxbaumia indusiata</i>, <i>Leskea sericea</i>, <i>Hypnum lutescens</i>,
+<i>Anomodon alternatus</i>, <i>Clinacium dendroides</i>, <i>Bryum c&aelig;spititium</i>,
+<i>Brachythecium plumosum</i>, <i>Mnium serratum</i>, <i>Splachnum vasculosum</i>. It

+<p><b>Synspermy, or Union of the Seeds.</b>&mdash;Seeds may be united together in
+various degrees, either by their integuments,<a name="FNanchor_55_55" id="FNanchor_55_55"></a><a href="#Footnote_55_55" class="fnanchor">[55]</a> or by their inner
+parts. Such union of the seeds, however, is of rare occurrence. It takes
+place normally, to a slight extent, in certain cultivated forms of
+cotton, wherein the seeds are aggregated together into a reniform mass,
+whence the term kidney cotton. Union of the parts of the embryo is
+treated under another head (see Synophty).</p>
+
+
+
+<p><b>Adhesion between the axes of different plants.</b>&mdash;Under this head may be
+classed the union that takes place between the stems, branches, or roots
+of different plants of the same species, and that which occurs between
+individuals of different species; the first is not very different in its
+nature from cohesion of the branches of the same plant (figs. 21, 22).
+It finds its parallel, under natural circumstances, among the lower
+cryptogams, in which it often happens that several individual plants,
+originally distinct, become inseparably blended together into one mass.
+In the gardening operations of inarching, and to some extent in budding,
+this adhesion of axis to axis occurs, the union taking place the more
+readily in proportion as the contact between the younger growing
+portions of the two axes respectively is close. The huge size of some
+trees has been, in some cases, attributed to the adnation of different
+stems. This is said to be the case with the famous plane trees of
+Bujukdere, near Constantinople, and in which nine trunks are more or
+less united together.<a name="FNanchor_56_56" id="FNanchor_56_56"></a><a href="#Footnote_56_56" class="fnanchor">[56]</a></p>

+<p>A similar anastomosis may take place in the roots. Lindley cites a case
+wherein two carrots, of the white Belgian and the red Surrey varieties
+respectively, had grown so close to each other that each twisted half
+round the other, so that they ultimately became soldered together; the
+most singular thing with reference to this union was, that the red
+carrot<span class='pagenum'><a name="Page_51" id="Page_51">[Pg 51]</a></span> (fig. 23, <i>b</i>), with its small overgrown part above the
+junction, took the colour and large dimensions of the white Belgian
+(<i>d</i>), which, in like manner, with its larger head above the joining
+(<i>a</i>), took the colour and small dimensions of the red one at and below
+the union (<i>e d</i>). The respective qualities of the two roots<span class='pagenum'><a name="Page_52" id="Page_52">[Pg 52]</a></span> were thus
+transposed, while the upper portions or crowns were unaffected: the root
+of one, naturally weak, became distended and enlarged by the abundant
+matter poured into it by its new crown; and in like manner the root of
+the other, naturally vigorous, was starved by insufficient food derived
+from the new crown, and became diminutive and shrunken (see Synophty).</p>

+<p>The explanation of the fact that the stumps of felled fir trees

+<p>A not uncommon malformation in mushrooms arises from the confluence of

+
+<p>Mr. Darwin, in his work on the 'Variation of Animals and Plants,' vol.
+i, p. 395, alludes to the two following remarkable cases of
+fusion:&mdash;"The author of 'Des Jacinthes' (Amsterdam, 1768, p. 124) says
+that bulbs of blue and red hyacinths may be cut in two, and that they
+will grow together, and throw up a united stem (and this Mr. Darwin has
+himself seen), with flowers of the two colours on the opposite sides.
+But the remarkable point is, that flowers are sometimes produced with
+the two colours blended together." In the second case related by Mr.
+Trail, about sixty blue and white potatoes were cut in halves through
+the eyes or buds, and the halves were then joined, the other buds being
+destroyed. Union took place, and some of the united tubers produced
+white, others<span class='pagenum'><a name="Page_55" id="Page_55">[Pg 55]</a></span> blue, while some produced tubers partly white and partly
+blue.</p>
+
+
+
+<p><b>Adhesion of the axes of plants belonging to different species is a</b> more
+singular occurrence than the former, and is of some interest as
+connected with the operation of grafting. As a general rule
+horticulturists are of opinion, and their opinion is borne out by facts,
+that the operation of grafting, to be successful, must be practised on
+plants of close botanical affinity. On the other hand, it is equally
+true that some plants very closely allied cannot be propagated in this
+manner. Contact between the younger growing tissues is essential to
+successful grafting as practised by the gardener, and is probably quite
+as necessary in those cases where the process takes place naturally.
+Although there is little doubt but that some of the recorded instances
+of natural or artificial grafting of plants of distant botanical
+affinities are untrustworthy, yet the instances of adhesion between
+widely different plants are too numerous and too well attested to allow
+of doubt. Moreover, when parasitical plants are considered, such as the
+Orobanches, the Cuscutas, and specially the mistleto (<i>Viscum</i>), which
+may be found growing on plants of very varied botanical relationship,
+the occurrence of occasional adhesion between plants of distant affinity
+is not so much to be wondered at. Union between the haulms of wheat and
+rye, and other grasses, has been recorded<a name="FNanchor_60_60" id="FNanchor_60_60"></a><a href="#Footnote_60_60" class="fnanchor">[60]</a>. Moquin-Tandon<a name="FNanchor_61_61" id="FNanchor_61_61"></a><a href="#Footnote_61_61" class="fnanchor">[61]</a> relates
+a case wherein, by accident, a branch of a species of <i>Sophora</i> passed
+through the fork, made by two diverging branches of an elder
+(<i>Sambucus</i>), growing in the Jardin des Plantes of Toulouse. The branch
+of the <i>Sophora</i> contracted a firm adhesion to the elder, and what is
+remarkable is that, although the latter has much<span class='pagenum'><a name="Page_56" id="Page_56">[Pg 56]</a></span> softer wood than the
+former, yet the branch of the harder wooded tree was flattened, as if
+subjected to great pressure<a name="FNanchor_62_62" id="FNanchor_62_62"></a><a href="#Footnote_62_62" class="fnanchor">[62]</a>. It is possible that some of the cases
+similar to those spoken of by Columella, Virgil<a name="FNanchor_63_63" id="FNanchor_63_63"></a><a href="#Footnote_63_63" class="fnanchor">[63]</a>, and other classical
+writers, may have originated in the accidental admission of seeds into
+the crevices of trees; in time the seeds grew, and as they did so, the
+young plants contracted an adhesion to the supporting tree. Some of the
+instances recorded by classical writers may be attributed to intentional
+or accidental fallacy, as in the so-called "greffe des charlatans" of
+more modern days.</p>
+
+<p>Adhesion of the roots of different species has been effected
+artificially, as between the carrot and the beet root, while Dr. Maclean
+succeeded in engrafting, on a red beet, a scion of the white Silesian
+variety of the same species. In all these cases, even in the most
+successful grafts, the amount of adhesion is very slight; the union in
+no degree warrants the term fusion, it is little but simple contact of
+similar tissues, while new growing matter is formed all round the cut
+surfaces, so that the latter become gradually imbedded in the newly
+formed matter.</p>
+
+
+
+<p><b>Synophty or adhesion of the embryo.</b>&mdash;This often occurs partially in the
+embryo plants of the common mistleto (<i>Viscum</i>), but is not of common
+occurrence in other plants, even in such cases as the orange (<i>Citrus</i>),
+the <i>Cycade&aelig;</i>, <i>Conifer&aelig;</i>, &amp;c., where there is frequently more than one
+embryo in the seed. Alphonse De Candolle has described and figured an
+instance of the kind in <i>Euphorbia helioscopia</i>, wherein two embryo
+plants were completely grafted together throughout the whole length<span class='pagenum'><a name="Page_57" id="Page_57">[Pg 57]</a></span> of
+their axes, leaving merely the four cotyledons separate. A similar
+adnation has been observed by the same botanist in <i>Lepidium sativum</i>
+and <i>Sinapis ramosa</i>, as well as in other plants.<a name="FNanchor_64_64" id="FNanchor_64_64"></a><a href="#Footnote_64_64" class="fnanchor">[64]</a> I have met with
+corresponding instances in <i>Antirrhinum majus</i> and in <i>Crat&aelig;gus
+oxyacantha</i>, in the latter case complicated with the partial atrophy of
+one of the four cotyledons. It is necessary to distinguish between such
+cases and the fallacious appearances arising from a division of the
+cotyledons. M. Morren has figured and described the union of two roots
+of carrot (<i>Daucus</i>), which were also spirally twisted. He attributes
+this union to the blending of two radicles, and applies the term
+"rhizocollesy" to this union of the roots.<a name="FNanchor_65_65" id="FNanchor_65_65"></a><a href="#Footnote_65_65" class="fnanchor">[65]</a> Mr. Thwaites cites a case
+wherein two embryos were contained in one seed in a <i>Fuchsia</i>, and had
+become adherent. What is still more remarkable, the two embryos were
+different, a circumstance attributable to their hybrid origin, the seed
+containing them being the result of the fertilisation of <i>Fuchsia
+coccinea</i> (quere <i>F. magellanica?</i>) by the pollen of <i>F. fulgens</i>.</p>

+<h3><a name="PART_II" id="PART_II"></a>PART II.<br />
+
+INDEPENDENCE OR SEPARATION OF ORGANS.</h3>
+
+
+<p>Under this head are included all those instances wherein organs usually
+entire, or more or less united, are, or appear to be, split or
+disunited. It thus includes such cases as the division of an ordinarily
+entire leaf into a lobed or partite one, as well as those characterised
+by the separation of organs usually joined together. Union, as has been
+stated in a previous chapter, is the result either of persistent
+integrity or of a junction of originally separate organs, after their
+formation; so in like manner, the separation or disjunction of parts may
+arise from the absence of that process of union which is habitual in
+some cases, or from an actual <i>bon&acirc; fide</i> separation of parts originally
+united together. In the former case, the isolation of parts arises from
+arrest of development, while in the latter it is due rather to luxuriant
+growth. A knowledge, as well of the ordinary as of the unusual course,
+of development in any particular flower is thus required in order to
+ascertain with accuracy the true nature of the separation of parts. The
+late Professor Morren<a name="FNanchor_66_66" id="FNanchor_66_66"></a><a href="#Footnote_66_66" class="fnanchor">[66]</a> proposed the general term Monosy (<span class="greek" title="[Greek:
+mon&ocirc;sis]">&#956;&#959;&#957;&#969;&#963;&#953;&#962;</span>) for all these cases of abnormal isolation, subdividing the
+group into two, as follows&mdash;1, Adesmy (<span class="greek" title="[Greek: a-desmos]">&#945;-&#948;&#949;&#963;&#956;&#959;&#962;</span>), including
+those cases where the separation is congenital; and 2, Dialysis (<span class="greek" title="[Greek:
+dialy&ocirc;]">&#948;&#953;&#945;&#955;&#965;&#969;</span>), comprising those instances where the isolation is truly a
+result of the separation of parts previously joined together. Adesmy,
+moreover,<span class='pagenum'><a name="Page_59" id="Page_59">[Pg 59]</a></span> was by the Belgian savant said to be homologous when it
+occurred between members of the same whorl, <i>e.g.</i> between the sepals of
+an ordinary monosepalous calyx, or heterologous when the separation took
+place between members of different whorls, as when the calyx is detached
+from the ovary, &amp;c. The former case would thus be the converse of
+cohesion, the latter of adhesion.</p>
+
+<p>To the adoption of these words there is this great objection, that we
+can but rarely, in the present state of our knowledge, tell in which
+group any particular illustration should be placed.</p>
+
+<p>The terms adopted in the present work are, for the most part, not
+necessarily intended to convey any idea as to the organogenetic history
+of the parts affected. Where a single organ, that is usually entire,
+becomes divided the term Fission is used; in cases where parts of the
+same whorl become isolated, the word Dialysis is employed, and in the
+same sense in which it is generally used by descriptive botanists, and
+where the various whorls become detached one from the other, the
+occurrence is distinguished by the application of the term Solution.</p>

+
+FISSION.</h4>
+
+
+<p>When an organ becomes divided it receives at the hands of descriptive
+botanists the appellations cleft, partite, or sect, according to the
+depth of the division; hence in considering the teratological instances
+of this nature, the term fission has suggested itself as an appropriate
+one to be applied to the subdivision of an habitually entire or
+undivided organ. It thus corresponds pretty nearly in its application
+with the term Chorisis<span class='pagenum'><a name="Page_60" id="Page_60">[Pg 60]</a></span> or "d&eacute;doublement," or with the "disjonctions qui
+divisent les organes" of Moquin-Tandon.<a name="FNanchor_67_67" id="FNanchor_67_67"></a><a href="#Footnote_67_67" class="fnanchor">[67]</a> It is usually, but not
+always, a concomitant with hypertrophy, and dependent on luxuriance of
+growth.</p>
+
+<p>It must be understood therefore that the term, as generally applied,
+does not so much indicate the cleavage of a persistent organ, as it does
+the formation and development of two or more growing points instead of
+one, whence results a branching or forking (di-tri-chotomy) of the
+affected organ. In some instances it seems rather to be due to the
+relative deficiency of cellular, as contrasted with fibro-vascular
+tissue.</p>
+
+
+
+<p><b>Fission of axile organs.</b>&mdash;This condition is scarcely to be distinguished
+from multiplication of the axile organs (which see). A little attention,
+however, will generally show whether the unusual number of branches is a
+consequence of the development of a large number of distinct shoots, as
+happens, for instance, when a tree is pollarded, or of a division of
+one. M. Fournier<a name="FNanchor_68_68" id="FNanchor_68_68"></a><a href="#Footnote_68_68" class="fnanchor">[68]</a> gives as an illustration the case of a specimen of
+<i>Ruscus aculeatus</i> in which there occurred a division of the foliaceous
+branches into two segments, reaching as far as the insertion of the
+flower, but no further. He also mentions lateral cleavage effected by a
+notching of the margin, the notch being anterior to the flowers and
+always directed towards their insertion. In the allied genus <i>Dana&euml;</i>,
+Webb, 'Phyt. Canar.,' <a href="#Page_320">p. 320</a>, describes the fascicles of flowers as in
+"crenulis brevibus ad marginem ramulorum dispositis." Sometimes, on the
+other hand, <i>Dana&euml;</i> has a fascicle of flowers inserted on the middle of
+the upper surface, as in <i>Ruscus</i>. Wigand mentions an instance in
+<i>Digitalis lutea</i>, where the upper part of the stem was divided into six
+or seven racemes; possibly this was a case of fasciation, but such a
+division of the inflorescence is by no means uncommon in the spicate
+species of <i>Veronica</i>. I have<span class='pagenum'><a name="Page_61" id="Page_61">[Pg 61]</a></span> also seen it in <i>Plantago lanceolata</i>,
+<i>Reseda luteola</i>, <i>Campanula medium</i>, <i>Epacris impressa</i>, and a
+bifurcation of the axis of the spikelet within the outer glumes in
+<i>Lolium perenne</i><a name="FNanchor_69_69" id="FNanchor_69_69"></a><a href="#Footnote_69_69" class="fnanchor">[69]</a> and <i>Anthoxanthum odoratum</i>. In the Kew Museum is
+preserved a cone of <i>Abies excelsa</i>,<a name="FNanchor_70_70" id="FNanchor_70_70"></a><a href="#Footnote_70_70" class="fnanchor">[70]</a> dividing into two divisions,
+each bearing bracts and scales. A similar thing frequently occurs in the
+male catkins of <i>Cedrus Libani</i> (fig. 25).</p>

+
+<p>This subdivision of axial organs is not unfrequently the result of some
+injury or mutilation, thus Duval Jouve alludes to the frequency with
+which branched stems are produced in the various species of <i>Equisetum</i>,
+as a consequence of injuries to the main stem, but this is rather to be
+considered as a multiplication of parts than as a subdivision of one.</p>

+
+<p><b>Fission of foliar organs.</b>&mdash;Many leaves exhibit constantly the process of
+fission, such as the <i>Salisburia adiantifolia</i>, and which is due perhaps
+as much to the absence or relatively small proportion of cellular as
+compared with vascular tissue, as to absolute fission. In the same way
+we have laciniated leaves of the Persian lilac, <i>Syringa persica</i>, and
+Moquin mentions instances in a species of<span class='pagenum'><a name="Page_62" id="Page_62">[Pg 62]</a></span> <i>Mercurialis</i> in which the
+leaves were deeply slashed. In <i>Chenopodium Quinoa</i> the leaves were so
+numerous and the clefts so deep, that the species was hardly
+recognisable, while on a branch of <i>Rhus Cotinus</i> observed by De
+Candolle the lobes were so narrow and so fine as to give the plant the
+aspect of an <i>Umbellifer</i>. Wigand ('Flora,' 1856, p. 706) speaks of the
+leaves of <i>Dipsacus fullonum</i> with bi-partite leaves; Moquin mentions
+the occurrence of a leaf of an oleander bi-lobed at the summit, so as to
+give the appearance of a fusion of two leaves. Steinheil has recorded an
+instance in <i>Scabiosa atropurpurea</i> in which one of the stem leaves
+presented the following peculiarities. It was simple below, but divided
+above into two equal lobes, provided each with a median nerve.<a name="FNanchor_71_71" id="FNanchor_71_71"></a><a href="#Footnote_71_71" class="fnanchor">[71]</a>
+Steinheil has also recorded a <i>Cerastium</i> in which one of the leaves was
+provided with two midribs; above this leaf was a group of ternate
+leaves. I have seen similar instances in the common Elm, <i>Ulmus
+campestris</i>, and also in the common nettle, <i>Urtica dioica</i>,<span class='pagenum'><a name="Page_63" id="Page_63">[Pg 63]</a></span> the leaves
+of which latter thus resembled those of <i>Urtica biloba</i>, which are
+habitually bilobed at the summit. M. Clos<a name="FNanchor_72_72" id="FNanchor_72_72"></a><a href="#Footnote_72_72" class="fnanchor">[72]</a> mentions an instance where
+the terminal leaf and first bract of <i>Orchis sambucina</i> were divided
+into two segments. The same author also mentions the leaves of
+<i>Anemiopsis californica</i>, which were divided in their upper halves each
+into two lobes&mdash;also leaves of a lentil springing from a fasciated stem
+and completely divided into two segments, but with only a single bud in
+the axil. The axillary branches in like manner showed traces of
+cleavage. Fig. 26 represents a case of this kind in <i>Lamium album</i>,
+conjoined with suppression of the flowers on one side of the stem. I
+have also in my herbarium a leaf of <i>Arum maculatum</i>, with a stalk
+single at the base, but dividing into two separate stalks, each bearing
+a hastate lamina, the form of which is so perfect that were it not from
+the venation of the sheath it would be considered that there was here a
+union of two leaves rather than a bifurcation of one. A garden
+Pelargonium presented the same appearance.</p>

+
+<p>Fern fronds are particularly liable to this kind of subdivision, and
+they exhibit it in almost every degree, from a simple bifurcation of the
+frond to the formation of large tufts of small lobes all formed on the
+same plan by the repeated forking of the pinnules. These may be
+considered as cases of hypertrophy.</p>
+
+<p>Moquin-Tandon, at a meeting of the Botanical Society<span class='pagenum'><a name="Page_64" id="Page_64">[Pg 64]</a></span> of France (April
+3rd, 1858) exhibited a leaf of <i>Cerasus Lauro-Cerasus</i> divided in such a
+manner as to resemble a leaf of <i>Citrus</i> or of <i>Phyllarthron</i>. In this
+case, therefore, the disunion must have taken place laterally, and not
+from apex towards base, as is most common. The leaves of the common
+horse-radish, <i>Cochlearia Armoracia</i>, are very subject to this pinnated
+subdivision of the margin, and numerous other illustrations might be
+given.</p>

+<p>A. Braun describes a singular case in a leaf of <i>Irina</i><span class='pagenum'><a name="Page_65" id="Page_65">[Pg 65]</a></span> <i>glabra</i>
+wherein the blade of the leaf on one side was deeply and irregularly
+laciniated, the other side remaining entire. (Verhandl., d. 35,
+<ins title="Naturvorschefversammlung in original">Naturforscherversammlung</ins>, tab. 3.) Laciniate varieties of plants are of
+frequent occurrence in gardens where they are often cultivated for their
+beauty or singularity; thus, there are laciniated alders, fern-leaved
+beeches and limes, oak-leaved laburnums, &amp;c. A list of several of these
+is subjoined. A similar fission takes place constantly in the cotyledons
+of some plants, sometimes, as in <i>Conifer&aelig;</i>, to such an extent as to
+give an appearance as if there were several cotyledons.<a name="FNanchor_73_73" id="FNanchor_73_73"></a><a href="#Footnote_73_73" class="fnanchor">[73]</a></p>
+
+<p>It is not always easy to recognise, at a first glance, whether the
+division be the result of disunion or of an incomplete union of two
+leaves, but we may be guided by the number of leaves in the cycle or the
+whorl. The number is complete in cases of partial disjunction, while in
+cases of fusion it is incomplete. Again, in instances of disjunction,
+there is only one point of origin, but, when two leaves are grafted
+together, two such points may generally be detected at the base of the
+leaf, or a transverse section of the leaf-stalk will show indications of
+fusion. The number and position of the midribs will also serve as a
+guide, as in cases of fusion there are generally two or more midribs,
+according to the number of fused leaves; but as Moquin well remarks,
+this latter character cannot be always depended upon, for the median
+nerve may divide without any corresponding separation of the cellular
+portions of the leaf. The author just quoted cites examples of this kind
+in <i>Cardamine pratensis</i>, <i>Hedera Helix</i>, <i>Plantago major</i>, <i>Geranium
+nodosum</i>.</p>
+
+<p>The following list of plants commonly producing leaves that are cleft or
+divided, to a greater extent than is usual in the species, is mainly
+taken from one given by Schlechtendal, 'Bot. Zeit.,' 1844, p. 441, with
+additions from other sources. The ! indicates that the author has
+himself met with the deviation in<span class='pagenum'><a name="Page_66" id="Page_66">[Pg 66]</a></span> question. Many are cultivated as

+<p><b>Fission of the petals, &amp;c.</b>&mdash;The floral leaves are subject to a similar
+process of cleavage to that which has just<span class='pagenum'><a name="Page_67" id="Page_67">[Pg 67]</a></span> been mentioned as taking
+place in the leaves. This, indeed, occurs very often as a normal
+occurrence as in the petals of mignonette (<i>Reseda</i>), or those of
+<i>Alsine media</i> and many other plants. Here, however, we have only to
+allude to those instances in which the cleavage occurs in flowers whose
+sepals or petals are usually entire. Under this category Moquin mentions
+a petal of <i>Brassica oleracea</i> completely split into two. Linn&eacute; in his
+'Flora Lapponica' (pp. 145 and 164) mentions quadrifid petals of
+<i>Lychnis dioica</i>, and much divided petals of <i>Rubus arcticus</i>. Among
+other plants subject to this division of sepals or petals may be
+mentioned as having come within the writer's personal observation,
+<i>Ranunculus Lingua</i>, <i>R. acris</i>, <i>Papaver somniferum</i>, and others of
+this genus, <i>Saponaria sp.</i>, <i>Dianthus</i>, <i>Narcissus</i>, &amp;c.</p>
+
+<p>In some of the garden varieties of <i>Cyclamen</i> the corolla looks at first
+sight as if double, and the plan of the flower is oblong or elliptical,
+instead of circular. In these flowers each lobe of the corolla is
+divided almost to the base into two lobes, so that there appear to be
+ten lobes to the corolla instead of five, as usual. The stamens are
+normal in form and number in these flowers.</p>
+
+<p>In the paroquet tulips of gardeners the segments of the perianth are
+deeply and irregularly gashed, the segments occasionally becoming rolled
+up and their margins coherent so as to form little tubular spurs. I have
+also noticed the segments of the perianth in <i>Crocus</i> and <i>Colchicum</i>
+deeply cleft, so much so sometimes, as to equal in this particular the
+stigmas. In the flowers of a species of <i>Oncidium</i>, communicated to me
+by Mr. Currey, the lip was divided into three segments perfectly
+distinct one from the other, but confluent with the column; the two side
+pieces had callosities at the upper edge close to the base, the central
+piece had a similar wartlike process in its centre. In these flowers the
+ovary, the stigma, and the anther were all in a rudimentary condition.
+Some verbenas raised by Mr.<span class='pagenum'><a name="Page_68" id="Page_68">[Pg 68]</a></span> Wills offer a curious illustration of this
+condition. It will be remembered that some of the lobes or petals of a
+verbena are normally divided at the base to a slight degree, but in the
+flowers in question this is carried to such an extent that the enlarged
+lobes are pushed into the centre of the flower and simulate, at a first
+glance, a distinct and separate organ, though in reality it is but an
+enlargement of what occurs normally.<a name="FNanchor_74_74" id="FNanchor_74_74"></a><a href="#Footnote_74_74" class="fnanchor">[74]</a></p>

+<p class="caption"> <span class="smcap">Fig.</span> 29.&mdash;Flower of <i>Oncidium sp.</i> seen from the back. The lip is divided into three unequal segments.</p>
+</div>
+
+<p>Moquin mentions having seen the stamens of <i>Matthiola incana</i> and
+<i>Silene conica</i> completely divided, each section bearing half an anther,
+exactly as happens in <i>Polygalace&aelig;</i>. In tulips and lilies the same
+author mentions division of the anther only, the filament remaining
+entire, as happens naturally in many species of <i>Vaccinium</i>.</p>
+
+<p>A division of the individual carpels occurs very frequently when those
+organs become more or less leafy, as in <i>Trifolium repens</i>, and other
+plants to be hereafter mentioned.</p>
+
+<p>The instances given in this chapter have all been cases wherein the
+division or the accessory growth has taken place in one plane only and
+that plane<span class='pagenum'><a name="Page_69" id="Page_69">[Pg 69]</a></span> the same as that of the affected organ, but there are other
+examples, probably equally due to fissiparous division, where the new
+growth is either parallel to, or even at angle with the primary organ.
+Of such nature are some of those instances wherein two leaves appear to
+be placed back to back. These partake of the nature of excrescences or
+of exaggerated developments, and hence will be more fully treated of
+under the head of hypertrophy. It must be remembered that in some of
+these cases the fission may be a resumption of characters proper to the
+species under natural conditions, but lost by cultivation or otherwise.
+Thus, Mr. Buckman accounts for "finger-and-toe" in root-crops on the
+principle of reversion to the wild form.</p>

+
+DIALYSIS.</h4>
+
+
+<p>This term is here made use of in the same sense as in descriptive
+botany, to indicate the isolation of parts of the same whorl; it is thus
+the opposite of cohesion. Morren, as has been previously stated,
+employed the word in a different sense, while Moquin-Tandon<a name="FNanchor_75_75" id="FNanchor_75_75"></a><a href="#Footnote_75_75" class="fnanchor">[75]</a> included
+cases of this description under the category of "Disjonctions qui
+isolent les organes."</p>
+
+<p>Dialysis, as here understood, may be the result of an arrest of
+development, in consequence of which parts that under ordinary
+circumstances would become fused, do not do so; or, on the other hand,
+it may be the result of an actual separation between parts primitively
+undivided. As it is not possible in every case to distinguish between
+the effects of these two diverse causes, no attempt is here made to do
+so.</p><p><span class='pagenum'><a name="Page_70" id="Page_70">[Pg 70]</a></span></p>
+
+
+
+<p><b>Dialysis of the margins of individual foliar organs.</b>&mdash;In cases where the
+leaf or leaf-like organ is ordinarily tubular or horn-like in form,
+owing to the cohesion of its edges, it may happen either from lack of
+union or from actual separation of the previously united edges, that the
+tubular shape is replaced by the ordinary flattened expansion. Thus, in
+<i>Eranthis hyemalis</i>, wherein the petals (nectaries) are tubular and the
+sepals flat, I have met with numerous instances of transition from the
+one form to the other, as shown in fig. 9, p. 24.</p>
+
+<p>It is, however, in the carpels that this separation occurs most
+frequently. When these organs appear under the guise of leaves, as they
+often do, their margins are disunited, so that the carpel becomes flat
+or open. This happens in the strawberry (<i>Fragaria</i>), the columbine
+(<i>Aquilegia</i>), in <i>Trifolium repens</i>, <i>Ranunculus Ficaria</i>, &amp;c.<a name="FNanchor_76_76" id="FNanchor_76_76"></a><a href="#Footnote_76_76" class="fnanchor">[76]</a></p>
+
+
+
+<p><b>Dialysis of the parts of the same whorl:&mdash;calyx.</b>&mdash;The separation of an
+ordinarily coherent series into its constituent parts is necessarily of
+more common occurrence than the foregoing. As here understood, it is the
+precise converse of cohesion, and it may be represented diagrammatically
+by a dotted line above the letters denoting the sepals, petals, &amp;c. When
+this change happens in the calyx we have the gamosepalous condition
+replaced by the polysepalous one, as thus represented:</p>
+
+<pre>
+         .............
+         S  S  S  S  S
+instead of
+         _____________
+         S  S  S  S  S
+</pre>
+
+<p>as in a calyx of five coherent sepals.</p>
+
+<p>Detachment of this kind occurs not unfrequently, as in <i>Primula
+vulgaris</i>, <i>Trifolium repens</i>, &amp;c. In <i>Rosace&aelig;</i> and <i>Pomace&aelig;</i> this
+separation of the calyx is of the more moment, as it has reference to
+the structure of the<span class='pagenum'><a name="Page_71" id="Page_71">[Pg 71]</a></span> inferior ovary, as will be more fully mentioned
+hereafter. Here, however, a case recorded by M. J. E. Planchon may be
+alluded to<a name="FNanchor_77_77" id="FNanchor_77_77"></a><a href="#Footnote_77_77" class="fnanchor">[77]</a> wherein a quince fruit (<i>Cydonia</i>) was surmounted by five
+leaves, the surface of the pome being marked by as many prominences,
+which apparently corresponded to the five stalks of the calycine leaves.
+In this specimen, then, the inferior position of the ovary appeared to
+be not so much due to an expansion of the fruit stalk, as to the fusion
+of the hypertrophied stalks of the sepals. Some of the malformations
+among Cucurbits point to a similar structure. It is probable that in
+many of these cases the so-called inferior ovary is partly axial partly
+foliar, <i>i.e.</i>, sepaline, and partly carpellary in its nature.</p>
+
+<p>Dialysis of the sepals in calyces that are usually gamosepalous has been
+most frequently observed in <i>Rosace&aelig;</i>, <i>Pomace&aelig;</i>, <i>Umbellifer&aelig;</i>, less
+commonly in <i>Leguminos&aelig;</i>, also in the following genera:&mdash;<i>Primula</i>,
+<i>Symphytum</i>, <i>Gentiana</i>, <i>Campanula</i>, &amp;c.</p>
+

+<p class="caption"> <span class="smcap">Fig.</span> 30.&mdash;Dialysis of the sepals and petals in <i>Correa</i>.</p>
+</div>
+
+
+
+<p><b>Dialysis of the corolla</b> is likewise of frequent occurrence, either
+partially or to such an extent as to render the corolla truly
+polypetalous. Among <i>Labiat&aelig;</i> the upper lip of the corolla may be often
+met with partially<span class='pagenum'><a name="Page_72" id="Page_72">[Pg 72]</a></span> cleft, as it is constantly in <i>Phlomis biloba</i>, or
+more markedly among the <i>Lobeliace&aelig;</i>.</p>
+
+<p>In the <i>Composit&aelig;</i>, a similar separation of the petals is not
+infrequent, thus showing frequent transitional stages between the
+labiatifloral and tubulifloral divisions respectively. The ligulate
+corollas also may often be found in Chrysanthemums, Dahlias, &amp;c., more
+or less deeply divided into their component parts.</p>
+
+<p>A more complete separation occurs not unfrequently in <i>Campanula</i>,
+<i>Rhododendron</i>, <i>Phlox</i>, <i>&amp;c.</i> Figs. 30 and 31 illustrate dialysis of
+the corolla; the first in <i>Correa</i>, the second in <i>Campanula</i>.</p>

+
+<p>In the last-named genus, <i>C. rotundifolia</i> has been found with
+polypetalous flowers in a wild state in the mountains of Canton
+Neufchatel, Switzerland, and gave rise to the creation of a new genus.
+This form is now introduced into gardens.</p>
+
+<p>It must be remembered that in some genera, where this separation of the
+petals has been met with, there are species in which a similar isolation
+occurs normally, as in <i>Rhododendron</i>. <i>R. linearilobum</i>, a Japanese
+species, offers a good illustration of this.</p>
+

+</ul>
+</div>
+
+<p>This list does not include those very numerous cases in which this
+change is associated with more or less complete frondescence or leafy
+condition of the petals.</p>
+
+
+
+<p><b>Dialysis of the stamens.</b>&mdash;A similar isolation of the stamens occurs
+occasionally; for instance, when Mallows (<i>Malvace&aelig;</i>) become double, one
+of the first stages of the process is often the disjunction of the
+stamens, and a similar dissociation occurs in <i>Leguminos&aelig;</i> and
+<i>Composit&aelig;</i>, as in <i>Tragopogon</i>, as related by Kirschleger, in
+<i>Hypoch&aelig;ris</i> by Wigand, and in <i>Coreopsis</i> by Schlechtendal.</p>
+
+
+
+<p><b>Dialysis of the carpels.</b>&mdash;In the case of the carpels this disunion is
+more frequent than in the stamens. M. Seringe<a name="FNanchor_78_78" id="FNanchor_78_78"></a><a href="#Footnote_78_78" class="fnanchor">[78]</a> figures carpels of
+<i>Diplotaxis tenuifolia</i> more or less completely separated one from the
+other; indeed, this separation is very common amongst <i>Crucifer&aelig;</i> and
+<i>Umbellifer&aelig;</i>.</p>
+
+<p>Generally speaking, the disunion is complicated with frondescence&mdash;but
+not always so. I have, in my herbarium, specimens of <i>Convallaria
+majalis</i>, <i>Commelyna sp.</i>, and of <i>Lilium auratum</i>, in all of which the
+three carpels are completely disjoined, and present three<span class='pagenum'><a name="Page_74" id="Page_74">[Pg 74]</a></span> styles, three
+stigmas, &amp;c., without any other change. Engelmann<a name="FNanchor_79_79" id="FNanchor_79_79"></a><a href="#Footnote_79_79" class="fnanchor">[79]</a> speaks of three
+classes of this malformation. 1st, that in which the carpels separate
+one from the other without opening, as in the lily just alluded to; 2nd,
+that in which the ovary remains closed, but loses its internal
+partitions, as in a case mentioned by Moquin in <i>Stachys sylvatica</i>, in
+which, owing to imperfect disjunction, the two bi-lobed carpels were
+changed into a nearly one-celled capsule;<a name="FNanchor_80_80" id="FNanchor_80_80"></a><a href="#Footnote_80_80" class="fnanchor">[80]</a> and 3rd, those cases in
+which the carpels are open and foliaceous.</p>
+
+<div class="center">
+ <a name="fig032" id="fig032"></a>
+<a href="images/fig032m.jpg">

+  </a>
+<p class="caption"> <span class="smcap">Fig.</span> 32.&mdash;Anomalous form of orange.</p>
+</div>
+
+<p>Disjunction is more frequent in dry fruits than in fleshy ones. In the
+latter instance it happens at an early stage of existence, and the
+pericarp becomes more or less leafy, losing its faculty of becoming
+fleshy, as in <i>Prunus Cerasus</i> and <i>Amygdalus persica</i>; nevertheless,
+fleshy fruits sometimes become disunited. I have seen a case similar to
+that mentioned by M. Alphonse de Candolle in <i>Solanum esculentum</i>, in
+which the pericarp became ruptured, and the placentas protruded. A like
+occurrence has also been observed in a species of <i>Melastoma</i>.<a name="FNanchor_81_81" id="FNanchor_81_81"></a><a href="#Footnote_81_81" class="fnanchor">[81]</a> This
+is analogous to what happens in <i>Caulophyllum</i> and <i>Slateria</i>.
+Disjunction of the carpels<span class='pagenum'><a name="Page_75" id="Page_75">[Pg 75]</a></span> is not rare in oranges. Sometimes this takes
+place regularly, at other times irregularly; occasionally in such a
+manner as to give the appearance of a hand and fingers to the fruit. Of
+one of these, Ferrari,<a name="FNanchor_82_82" id="FNanchor_82_82"></a><a href="#Footnote_82_82" class="fnanchor">[82]</a> in the curious volume below cited, speaks
+thus: "Arbor profusissima, quia dat utraque manu; imo quia vere manus
+dat in poma conversis; utque magis munifica sit poma ipsa convertit in
+manus."</p>
+
+<p>M. Duchartre<a name="FNanchor_83_83" id="FNanchor_83_83"></a><a href="#Footnote_83_83" class="fnanchor">[83]</a> mentions a semi-double flower of orange with eight to
+ten distinct carpels in a whorl, and occasionally several whorls one
+above another. De Candolle<a name="FNanchor_84_84" id="FNanchor_84_84"></a><a href="#Footnote_84_84" class="fnanchor">[84]</a> considers the rind of the orange as a
+production from the receptacle, and this view is confirmed by the
+specimens of Duchartre, in which the carpels were quite naked or had a
+common envelope truncated, and open above to allow of the passage of the
+styles and stigmas.</p>

+
+<p>It frequently happens in conjunction with this separation of the carpels
+one from the other, that a lack of union manifests itself between the
+margins of the individual carpels themselves. Very numerous cases of
+this kind have been recorded, and the double tulips of gardens may be
+referred to as showing this condition<span class='pagenum'><a name="Page_76" id="Page_76">[Pg 76]</a></span> very frequently. In connection
+with this detachment of the carpels, a change in the mode of
+placentation is often to be observed, or two or more kinds may be seen
+in the same pistil, as in double-flowered saponarias, many Crucifers,
+&amp;c., as alluded to under the head of displacements of the placenta.</p>

+
+SOLUTION.</h4>
+
+
+<p>The isolation or separation of different whorls that are ordinarily
+adherent together is by no means of rare occurrence. Were it not that
+the isolation is often congenital, the word detachment would be an
+expressive one to apply to these cases, but as the change in question
+occurs quite as often from a want of union, an arrest or stasis of
+development, as from a <i>bon&acirc; fide</i> separation, the word solution seems
+to be, on the whole, the best. It corresponds in application to the word
+<i>liber</i> (<i>calyx liber</i>, &amp;c.), in general use by descriptive botanists.
+As here employed, the term nearly corresponds with the "adesmie
+het&eacute;rologue" of Morren. Moquin Tandon does not make any special
+subdivision for the class of cases here grouped together, but places
+them all under "Disjonctions qui isolent les organes." It seems,
+however, desirable to have a separate word to express the converse
+condition of adhesion, and for this purpose the term solution, as above
+stated, is here employed. Diagrammatically, the condition may be
+expressed by placing a dotted line at the side of the letters thus:</p>
+
+<pre>
+      : S S S S S :
+      : C C C C C :
+</pre>
+
+<p>would indicate the disjunction of the sepals from the<span class='pagenum'><a name="Page_77" id="Page_77">[Pg 77]</a></span> carpels (c), in
+contradistinction to adhesion, which may be represented by the unbroken
+line thus:</p>
+
+<pre>
+      | S S S S S |
+      | C C C C C |
+</pre>
+
+
+
+<p><b>Solution of the calyx from the ovary.</b>&mdash;Of all the instances of adhesion
+which take place under ordinary circumstances, that between the calyx
+and the ovary is perhaps the most common. The <i>calyx adh&aelig;rens</i> or
+<i>superus</i> is a structural characteristic to which all botanists attach
+considerable importance; so that when exceptional cases occur in which
+the calyx becomes detached from the ovary, becomes, that is, <i>inferus</i>
+or <i>liber</i>, a proportionate degree of interest attaches to the
+irregularity. It is not within the scope of the present work to inquire
+whether this detachment be real or merely apparent, arising from a want
+of union between parts ordinarily united together. This point must be
+left to the organogenists to decide in each particular case. So also the
+question as to what share, if any, the expanded and dilated flower-stalk
+may take in what are usually called inferior ovaries, can be here only
+incidentally touched upon.</p>
+
+<p>Among <i>Rosace&aelig;</i>, the change in question is very common, especially in
+conjunction with an elongation of the axis of the flower (apostasis) and
+with prolification, though it is by no means always co-existent with
+these malformations. When this alteration in the apparent relative
+position of calyx and carpels occurs in roses (<i>Rosa</i>) the appearances
+are generally such as to indicate that the "hip" of the rose is a
+dilatation of the peduncle, continuous above with the coherent bases of
+the sepals; this inference seems also to be borne out by what happens in
+the <i>Pomace&aelig;</i>. In some cases in this sub-order, the calyx becomes
+detached from the carpels, so that the latter organs become more or less
+"superior," and distinct one from the other. This happens constantly in
+the double-flowered<span class='pagenum'><a name="Page_78" id="Page_78">[Pg 78]</a></span> thorn, <i>Crat&aelig;gus Oxyacantha</i>, in some blossoms of
+which the hollowed end of the peduncle still invests the base of the
+carpels, leaving the upper portions detached. In apples flowers are
+occasionally met with of greater size than usual and on longer stalks,
+so that the whole looks more like a rose than an apple blossom. In these
+cases it will usually be found that the calyx consists of distinct
+sepals, without a trace of the ordinary swelling beneath the flower. The
+petals are often more numerous than usual; the stamens variously
+changed, and the carpels sometimes absent; at other times, as in the
+instance figured in the adjacent woodcuts, figs. 36, 37, consisting of
+separate, superior ovaries, sometimes destitute of ovules, or, at other
+times, having two of these bodies.<a name="FNanchor_85_85" id="FNanchor_85_85"></a><a href="#Footnote_85_85" class="fnanchor">[85]</a></p>

+
+<p>This condition accords precisely with the account<span class='pagenum'><a name="Page_79" id="Page_79">[Pg 79]</a></span> of the development of
+the flowers in <i>Pomace&aelig;</i> as given by Payer, Caspary, and others, so that
+the flowers above described would owe their deficiency of the swollen
+receptacle to an arrest of development. M. Germain de Saint Pierre,
+among other malformations of the rose, presented to the Botanical
+Society of France in 1854<a name="FNanchor_86_86" id="FNanchor_86_86"></a><a href="#Footnote_86_86" class="fnanchor">[86]</a> two specimens which are of special
+interest as relating to this contested point. In the one, the swollen
+portion beneath the flower was surmounted by five perfect leaves, as,
+indeed, is not infrequent in such malformations; here, then, the calyx
+could have had little or no share in the production of the swelling in
+question. In the other, the swollen portion was actually above the
+insertion of the sepals here represented by five perfect leaves.</p>

+
+<p>On the other hand, M. Planchon's specimen of the Quince before alluded
+to, not to mention other instances, tends to show that the bases of the
+sepals do sometimes enter into the composition of the pome. And, indeed,
+in many of these cases it would be impossible to say where the axial or
+receptacular portion ended, and the foliar portion began. As both from<span class='pagenum'><a name="Page_80" id="Page_80">[Pg 80]</a></span>
+normal organogeny as well as from unusual conformation contradictory
+inferences may be drawn, it would obviously be unsafe to attempt the
+explanation of the so-called calyx-tube in general from any particular
+instances; so far as <i>Rosace&aelig;</i> are concerned, there is so much variation
+in the relative position of calyx and carpels under ordinary
+circumstances, that it is no matter for surprise that similar
+diversities should exist in teratological cases. A similar remark will
+apply to <i>Saxifragace&aelig;</i>, <i>Cucurbitace&aelig;</i>, <i>Myrtace&aelig;</i>, <i>Bruniace&aelig;</i>,
+<i>Rubiace&aelig;</i>, and other families of like conformation.</p>

+</div>
+
+<p>In <i>Umbellifer&aelig;</i>, a detachment of the calyx from the ovaries frequently
+occurs, sometimes without any other change; at other times attended by
+more serious alterations. So far as can be judged from exceptional
+occurrences of this kind, it would appear that in this order the axis or
+flower-stalk does not, in any material degree, enter into the
+composition of the fruit.</p>
+
+<p>In the Rubiaceous genus <i>Bikkhia</i>, as mentioned by Duchartre, the ovary
+is completely inferior, but when the fruit arrives at maturity four
+small leaves are detached from its surface which had previously adhered
+to it, and which it seems reasonable to consider as the sepals.</p>
+
+<p>In <i>Campanulace&aelig;</i> a similar separation of calyx from the ovary may be
+occasionally met with. On the other hand, the occasional formation of a
+leaf on the inferior ovary of those plants would indicate the axial
+nature of the fruit. In <i>Campanum&aelig;a</i> and <i>Cyclodon</i> the calyx is
+inferior, while the corolla is superior. In the last-named genus this
+peculiarity "is carried to the highest degree, the sepals being, in <i>C.
+parviflorum</i>, placed on the peduncle of the flower far removed from the
+base of the corolla and ovary, whilst in <i>C. truncatum</i> and in<span class='pagenum'><a name="Page_81" id="Page_81">[Pg 81]</a></span>
+<i>Campanum&aelig;a</i> they adhere to the base of the tube of the corolla."<a name="FNanchor_87_87" id="FNanchor_87_87"></a><a href="#Footnote_87_87" class="fnanchor">[87]</a> In
+this order, then, as in <i>Saxifragace&aelig;</i>, <i>Bruniace&aelig;</i>, &amp;c., no hasty
+conclusion should be drawn as to the nature of the fruit. In <i>Brunia
+microphylla</i> the ovary is superior, enclosed within but not adnate to
+the cup-like calyx, to which latter, however, the petals and stamens are
+attached.</p>
+
+<p>In <i>Onagrace&aelig;</i> (<i>Jussieua</i>), as also in <i>Cactace&aelig;</i> (<i>Opuntia</i>), buds
+have been observed on the surface and edges of the inferior ovary.
+Indeed, in the former genus, they have been produced artificially, but
+as buds may be formed on foliar as well as on axial organs, the fact
+cannot be made great use of in support either of the foliar or axial
+nature of the inferior ovary. In <i>Epilobium</i>, I have met with four
+perfect leaves at the summit of the ovary, in the place usually occupied
+by the sepals. This would also favour the notion that the axis entered
+into the constitution of the fruit in this genus.</p>
+
+<p>Mr. B. Clarke, in his 'New Arrangement of Phanerogamous Plants,' p. 4,
+cites a case wherein the perianth was completely detached from the
+surface of the ovary in <i>Cannabis sativa</i>.</p>
+
+<p>It must be borne in mind that some of the recorded instances of change
+in the relative position of the calyx and pistil ought more properly to
+be referred to a substitution of carpels for stamens, as in <i>Begonia</i>,
+<i>Fuchsia</i>, &amp;c. Among <i>Cucurbitace&aelig;</i>, examples have been recorded, both
+of the detachment of the calyx from the ovary,<a name="FNanchor_88_88" id="FNanchor_88_88"></a><a href="#Footnote_88_88" class="fnanchor">[88]</a> and of the partial
+conversion of some of the anthers of the male flower to carpels.</p>
+
+<p>The very singular mode of germination of <i>Sechium edule</i> in which the
+fruit, instead of rotting, becomes thickened into a kind of rhizome or
+tuber, is a fact that should not be overlooked in investigating the true
+nature of the fruit in this order.</p><p><span class='pagenum'><a name="Page_82" id="Page_82">[Pg 82]</a></span></p>
+
+<p>The following are the genera in which the change has been most
+frequently observed:</p>

+
+ALTERATIONS OF POSITION.</h3>
+
+
+<p>Necessarily connected with changes in the arrangement of organs are
+similar alterations in their position; so closely, indeed, that but for
+convenience sake, it would be unnecessary to treat them separately.
+There are, however, some anomalous developments affecting the relative
+position of organs that could hardly be treated of under any of the
+preceding paragraphs. There are, also, certain rare instances where an
+organ is not so much displaced as misplaced; that is to say, it is
+developed on or from a portion of the plant, which under usual
+circumstances does not produce such an organ. In the former instance,
+the altered position is due to or coexistent with other changes, but in
+the latter case the new growth may spring from organs otherwise in
+nowise different from ordinary. The word Displacement is here used to
+signify the unusual position of an organ; while Heterotaxy may serve to
+include those cases where a new growth makes its appearance in an
+unwonted situation, as, for instance, a leaf-bud on a root, &amp;c.
+Prolification is also included under this heading, the unusual position
+of the buds in these cases being of graver import than the mere increase
+in number. Alterations in the position of the sexual organs are spoken
+of under the head of Heterogamy.</p><p><span class='pagenum'><a name="Page_84" id="Page_84">[Pg 84]</a></span></p>
+
+

+
+<h4><a name="CHAPTER_Ic" id="CHAPTER_Ic"></a>CHAPTER I.<br />
+
+DISPLACEMENT.</h4>
+
+
+<p>Real or apparent displacement of organs from their usual position is an
+almost necessary consequence of, or is, at least, coexistent with a
+large number of teratological phenomena. It is obvious that abnormal
+unions or disunions, suppressions, hypertrophies, &amp;c., are very liable
+to bring about or to be accompanied with changes in the position, either
+of the parts directly affected or of adjoining organs.</p>
+
+<p>In this place, then, it is merely necessary to allude to some of the
+more important displacements, and to refer for further details to the
+sections relating to those irregularities of growth on which the
+displacement depends.</p>
+
+
+
+<p><b>Displacement of bulbs.</b>&mdash;I owe to the kindness of Mr. James Salter a
+tulip bulb which had been dug up after flowering, and from the base of
+which were suspended several small bulbs; and I have since seen another
+specimen showing the same unusual arrangement. The explanation of these
+formations seems to be that they correspond to the bulbils ordinarily
+found in the axils of the scales of the parent organ, and which, in some
+way or another, have been displaced and thrust into the ground.
+Professor de Vriese figures something of the same kind in <i>Ixia
+carminosa</i>.<a name="FNanchor_90_90" id="FNanchor_90_90"></a><a href="#Footnote_90_90" class="fnanchor">[90]</a></p>
+
+<p>Of somewhat different nature to those above described was an anomaly
+described by M. Gay at a meeting of the Botanical Society of France,
+April 8th, 1859. The plant affected was <i>Leucoium &aelig;stivum</i>, and the
+changes observed were apparently attributable to a simple separation of
+two leaves that are usually contiguous. "Suppose," says M. Gay in
+describing this<span class='pagenum'><a name="Page_85" id="Page_85">[Pg 85]</a></span> malformation, "the first leaf of the terminal bud
+separated by a long internode from the other leaves, which remain
+closely packed; and further, suppose an evident thickening of the upper
+portion of the lengthened internode, and there will be not only a single
+bulb, bearing with the leaves of the present year all the remnants of
+the leaves of the two preceding years, but two bulbs placed one above
+another, on the same axis, separated by the length of the internode."</p>

+<p class="caption"> <span class="smcap">Fig.</span> 39.&mdash;Unusual position of bulbs of tulip; the parent-bulb cut open.</p>
+</div>
+
+<p>The formation of bulbs in the axils of the leaves, as happens
+occasionally in tulips, is further alluded to under the head of
+hypertrophy.</p>
+
+
+
+<p><b>Displacements affecting the inflorescence.</b>&mdash;These are, for the most
+part, dependent on hypertrophy, elongation, atrophy, spiral torsion,
+&amp;c., but there are a few instances of a different nature, which may here
+be alluded to as not being coincident with any of the phenomena just
+mentioned. Sometimes these deviations from the ordinary position have
+the more interest as affecting<span class='pagenum'><a name="Page_86" id="Page_86">[Pg 86]</a></span> characters used to distinguish genera;
+thus one of the distinctions between rye-grass (<i>Lolium</i>) and wheat
+(<i>Triticum</i>) resides in the relative position of the spikelets and the
+main stem; in <i>Triticum</i> the spikelets are placed with their backs
+against the rachis, in <i>Lolium</i> with one edge against it; but in a
+specimen of rye-grass that has come under my own observation, the
+arrangement was that of <i>Triticum</i>.</p>
+
+<p>M. Kirschleger relates having found a specimen of <i>Leucanthemum
+pratense</i>, in which the ligulate female flowers were growing singly in
+the axils of the upper leaves of the stem.<a name="FNanchor_91_91" id="FNanchor_91_91"></a><a href="#Footnote_91_91" class="fnanchor">[91]</a> The ordinary capitulum
+would here seem to have been replaced by a spike or a raceme. A less
+degree of this change wherein a few flowers may be found, as it were,
+detached from the ordinary capitulum may often be observed in
+<i>Composit&aelig;</i>, <i><ins title="Dipsace&aelig; in original">Dipsacace&aelig;</ins></i>, &amp;c. I have also met with specimens of <i>Lamium
+album</i> in which some of the fascicles or clusters of flowers in place of
+being placed at the same level on opposite sides of the stem were placed
+alternately one above another.</p>
+
+<p>Caspary<a name="FNanchor_92_92" id="FNanchor_92_92"></a><a href="#Footnote_92_92" class="fnanchor">[92]</a> mentions a flower of <i>Aldrovanda vesiculosa</i>, which was
+elevated on a stalk that was adherent to the stem for a certain
+distance, and then separated from it. This flower, with the leaf to
+which it was axillary, evidently belonged to the whorl beneath, where
+there was a corresponding deficiency. Another flower of the same plant
+bore on its pedicel a small leaf, which was doubtless the bract raised
+above its ordinary position.</p>
+
+<p>M. Fournier mentions an instance in <i>Pelargonium grandiflorum</i>, where,
+owing to the lengthening of the axis, the pedicels, instead of being
+umbellate, had become racemose; and I owe to the kindness of Dr. Sankey
+a somewhat similar specimen, but in a less perfect condition. Here there
+was but a single flower, and that rudimentary, placed at the extremity
+of the<span class='pagenum'><a name="Page_87" id="Page_87">[Pg 87]</a></span> axis. There were several bracts beneath this flower disposed
+spirally in the 1/3 arrangement, all being empty, excepting the terminal
+one. In like manner, a head of flowers becomes sometimes converted into
+an umbel.</p>
+
+
+
+<p><b>Displacement of leaves.</b>&mdash;A cohesion of parts will sometimes give rise to
+an apparent displacement, but the true nature of the malformation can,
+in general, be readily made out.</p>
+
+<p>Steinheil<a name="FNanchor_93_93" id="FNanchor_93_93"></a><a href="#Footnote_93_93" class="fnanchor">[93]</a> found a specimen of <i>Salvia Verbenaca</i>, the leaves of
+which presented very curious examples of displacement arising from
+cohesion. Two of these leaves placed at the base of a branch were
+completely fused in their lower thirds, and divided into two distinct
+lobes at the upper part; each of these lobes seemed to be as large as
+the limb of an ordinary leaf. Above these was another very broad one,
+apparently entire, but evidently produced by a complete cohesion of two.
+This completely fused leaf alternated in position with the imperfectly
+fused one below it; the alternation is explained by supposing that the
+opposite leaves of each pair were directed one towards the other, and
+became fused, and that thus resulted the displacement. The dislocation
+of the organs took place in one direction for one pair of leaves, and in
+another direction for the other pair, hence the alternation. Thus,
+leaves normally opposite and decussate may, by fusion, become alternate.
+A similar instance occurred to the writer in <i>Lysimachia vulgaris</i>,
+wherein the changes arising from fusion and suppression of parts, &amp;c.,
+were very considerable; as far as the leaves were concerned they
+presented the following arrangement in succession from below
+upwards:&mdash;first verticillate, then opposite, then spirally alternate,
+lastly opposite.<a name="FNanchor_94_94" id="FNanchor_94_94"></a><a href="#Footnote_94_94" class="fnanchor">[94]</a> The term "diremption" has sometimes been applied to

+
+<p>Twisting of the stem is a frequent cause of the displacement of leaves
+(see spiral torsion), as also hypertrophy,<span class='pagenum'><a name="Page_89" id="Page_89">[Pg 89]</a></span> whether that excess of
+development take place laterally or lengthwise (see elongation). Atrophy
+or suppression will also frequently bring about an alteration in the
+position of leaves; sometimes in such a manner that the place of the
+suppressed organ is occupied by another one. One of the most curious
+instances of displacement of leaves arising from suppression is that
+mentioned by Morren,<a name="FNanchor_95_95" id="FNanchor_95_95"></a><a href="#Footnote_95_95" class="fnanchor">[95]</a> where, in <i>Gesnera Geroltiana</i>, a large leaf
+apparently occupied<span class='pagenum'><a name="Page_90" id="Page_90">[Pg 90]</a></span> the extremity of the axis, a position which, under
+ordinary circumstances, no leaf could assume. The explanation given by
+the Belgian professor is, that the axis in this case, instead of
+throwing off a pair of leaves, one on each side, had from some cause or
+another produced only one; this one not only being much larger than
+ordinary, but brightly coloured, thus assuming some of the
+characteristics as well as the position of the inflorescence.</p>
+
+<p>Alterations in the usual arrangement of leaves, however, are not always
+dependent on or coexistent with other teratological changes, but may
+simply depend on a natural elongation of the internodes, or on fission
+or multiplication; for instance, in some conifers, such as the Larch,
+(<i>Abies Larix</i>) or <i>Pinus pinea</i>, there may be found at different stages
+in the growth of the branches leaves in crowded fascicles or tufts;
+while, when growth is more rapid, the leaves may be disposed in a spiral
+or alternate manner.</p>
+
+<p>In the yew (<i>Taxus</i>) the leaves at the ends of the shoots not
+unfrequently lose their usual distichous arrangement and become arranged
+in a close spiral manner, the elongation of the shoot being arrested.
+This appears to be the result of the injury effected by some insect.</p>

+<p><b>Displacement of the parts of the flower.</b>&mdash;This subject is partly touched
+on in the chapters on solution, adhesion, and in those on hypertrophy,
+elongation, prolification, &amp;c., so that in this place it is only
+requisite to offer a few general remarks, and to refer to other sections
+for further details. Morren, in referring to displacement of the floral
+organs, mentions an instance in a <i>Fuchsia</i>, wherein the four petals in
+place of being alternate with the sepals were placed in front of them,
+owing to the adhesion that had taken place between the petals and the
+stamens. He speaks of this transposition as metaphery.<a name="FNanchor_97_97" id="FNanchor_97_97"></a><a href="#Footnote_97_97" class="fnanchor">[97]</a> The same
+author also gives an account of the displacement of several of the
+organs of the flower in <i>Cypripedium insigne</i>, the displacement being
+consequent, apparently, on a spiral torsion proceeding from right to
+left, and involving the complete or partial suppression of several of
+the organs of the flower. The dislocation of organs in a spiral
+direction led Morren to apply the term "speiranthie" to similar
+deviations from the usual construction. Changes of this kind among
+<i>Orchidace&aelig;</i> are by no means uncommon; the following may be cited by way
+of illustration. In a specimen of <i>Oncidium cucullatum</i> furnished me by
+Mr. Anderson, well known for his success as a cultivator of these
+plants, there was, associated with a cohesion of one sepal with another,
+and probably dependent on the same cause, a displacement of the sepals
+and petals&mdash;so that all were dragged out of place. This dislocation may
+be better appreciated by the accompanying formula than even<span class='pagenum'><a name="Page_92" id="Page_92">[Pg 92]</a></span> by the

+</div>
+
+<p>In a specimen of <i>Lycaste Skinneri</i> similar changes were observed, as
+shown in the plan, fig. 47. Here the posterior sepal was deficient, the
+two lateral ones were present, one of them with a long tubular spur, <i>o
+o</i>; of the two lateral petals, <i>i i</i>, one was twisted out of place, so
+as partially to occupy the place of the deficient sepal; the lip was
+represented by two three-lobed segments, <i>l</i>, one above and within the
+other. The<span class='pagenum'><a name="Page_94" id="Page_94">[Pg 94]</a></span> column and ovary of this flower were in their normal
+condition.</p>
+
+<p>Cohesion of two or more segments of the perianth is frequently
+associated with displacements of this nature: thus, in a flower of
+<i>Dendrobium nobile</i>, a diagram of which is given at fig. 48, the
+uppermost sepal was coherent with one of the lateral ones, and at the
+same time diminished in size, and, as it were, dragged out of position.
+All the other organs of the flower are also more or less displaced,
+forming a minor degree of the change already alluded to, and which
+Morren termed speiranthy. The changes will be better appreciated by
+comparing them with fig. 49, a diagram showing the natural arrangement
+of parts in this species.</p>

+</div>
+
+<p>Sometimes the displacement seems consequent on hypertrophy of one of the
+parts of the flower, the disproportionate size of one organ pushing the
+others out of place. This was the case in a violet, fig. 50, in which
+one of the sepals <i>s</i> was greatly thickened, and the petals and stamens
+were displaced in consequence.</p>

+</div>
+
+<p>It is curious to observe in many of these cases that the transposed
+organ not only<span class='pagenum'><a name="Page_95" id="Page_95">[Pg 95]</a></span> occupies the place of a suppressed or abortive organ,
+but frequently assumes its colour, and, to some extent, its function.
+This has been alluded to in the case of the leaf of <i>Gesnera</i> (<a href="#Page_88">see p.
+88</a>) and in Orchids this replacement seems to be very common; thus, in
+addition to the cases before mentioned, in a flower of an Odontoglossum,
+for which I am indebted to Professor Oliver, the two lateral sepals were
+united together and occupied the position of the labellum, which was
+absent. A similar occurrence happens occasionally in <i>Lycaste Skinneri</i>,
+thus recalling the structure of <i>Masdevallia</i>, where the labellum is
+normally very small. The arrangement in Lycaste may thus be symbolised:</p>

+</pre>
+
+<p>[Transcriber's note: The underscores represent a horizontal curly brace
+in the original.]</p>
+
+<p>the + indicating the position of the absent labellum.</p>
+
+<p>Cases of this kind are the more interesting from their relation to the
+fertilization of these flowers by insects; it seems as though, when the
+labellum, which performs so important an office in attracting and
+guiding insects, is deficient, its place is supplied by other means.</p>
+
+<p>Displacement of the parts of the flower from elongation of the
+receptacle is a not infrequent teratological occurrence, resulting
+sometimes in the conversion of the verticillate into the spiral
+arrangement. Instances of this are cited under Elongation,
+Prolification, &amp;c. In this place it is merely necessary to refer to a
+curious circumstance that is met with in some double flowers, owing to
+this separation of some parts of the flower and the cohesion or adhesion
+of others. Thus, in some double flowers of <i>Primula sinensis</i> and in the
+Pea (<i>Pisum sativum</i>), I have seen a gradual passage of sepals to
+petals, so that the calyx and corolla formed one continuous sheet,
+winding spirally around the<span class='pagenum'><a name="Page_96" id="Page_96">[Pg 96]</a></span> central axis of the flower, after the
+fashion of a spiral tube.<a name="FNanchor_98_98" id="FNanchor_98_98"></a><a href="#Footnote_98_98" class="fnanchor">[98]</a></p>
+
+
+
+<p><b>Displacement of the carpels</b> arises from one or other of the causes above
+alluded to, and when suppression takes place in this whorl it generally
+happens that the place of the suppressed organ is occupied by one of the
+remaining ones, which thus becomes partially dislocated.</p>
+
+
+
+<p><b>Displacement of the placentas and ovules</b> is a necessary result of many
+of the changes to which the carpels are subject. The disjunction or
+dialysis of the carpels, for instance, frequently renders axile
+placentation marginal. Moreover, it frequently happens, when the carpels
+become foliaceous and their margins are disconnected, that the ovules,
+in place of being placed on the suture, or rather on the margins of the
+altered carpel, are placed on the surface of the expanded carpel. Thus,
+in some double flowers of <i>Ranunculus Ficaria</i> that came under the
+writer's notice the carpels were open, <i>i.e.</i> disunited at the margins,
+and each bore two imperfect ovules upon its inner surface a little way
+above the base, and midway between the edges of the carpel and the
+midrib, the ovules being partly enclosed within a little depression or
+pouch, similar to the pit on the petals. On closer examination the
+ovules were found to spring from the two lateral divisions of the
+midrib, the vascular cords of which were prolonged under the form of
+barred or spiral fusiform tubes into the outer coating of the ovule. In
+this instance, then, the ovules did not originate from the margins of
+the leaf, nor from a prolonged axis, but they seemed to spring, in the
+guise of little buds, from the inner surface of the carpellary leaf.<a name="FNanchor_99_99" id="FNanchor_99_99"></a><a href="#Footnote_99_99" class="fnanchor">[99]</a></p>
+
+<p>The occurrence, also, of different forms of placentation<span class='pagenum'><a name="Page_97" id="Page_97">[Pg 97]</a></span> in different
+flowers on the same plant is no unusual thing in malformed flowers;
+thus, in double flowers of <i>Saponaria officinalis</i> I have met with
+sutural, parietal, and free central placentation in the same plant.<a name="FNanchor_100_100" id="FNanchor_100_100"></a><a href="#Footnote_100_100" class="fnanchor">[100]</a></p>
+
+<p>Professor Babington describes in the 'Gardeners' Chronicle,' 1844, p.
+557, a curious flower of <i>Cerastium</i>, in which, in addition to other
+changes, the five carpellary leaves "were partially turned in without
+touching the placenta, which bears a cluster of ovules, and is perfectly
+clear of all connection with those partitions" (fig. 51). See also

+<p>M. Baillon<a name="FNanchor_101_101" id="FNanchor_101_101"></a><a href="#Footnote_101_101" class="fnanchor">[101]</a> records flowers of <i>Bunias</i>, some with ovules on the
+margins of the carpels, others with a central branch bearing the ovules;
+hence he concludes<span class='pagenum'><a name="Page_98" id="Page_98">[Pg 98]</a></span> very justly that no fair inference can be drawn from
+these facts as to the normal placentation of Crucifer&aelig;.</p>
+
+<p>The same excellent observer has recorded the occurrence of free central
+placentation in malformed flowers of <i>Trifolium repens</i>.<a name="FNanchor_102_102" id="FNanchor_102_102"></a><a href="#Footnote_102_102" class="fnanchor">[102]</a></p>
+
+<p>In malformed flowers of <i>Digitalis</i> the change from axile to parietal
+placentation may often be seen. Mr. Berkeley describes an instance of
+this nature where the placentas were strictly parietal, and therefore
+receded from the distinctive characters of the order, and approximated
+to those of <i>Gesnerace&aelig;</i>.</p>
+
+<p>The same author alludes to certain changes in the same flower where two
+open carpels "were soldered together laterally, as was clear by the
+rudiments of two styles, the placenta being produced only at the two
+united edges, the outer margins remaining in the normal condition. This
+may possibly tend to the explanation of some cases of anomalous
+placentation, for the only indication of the true nature of the
+placentation is afforded by the two rudimentary styles, in the absence
+of which the spongy receptacle of the seeds must have been supposed to
+spring from the medial nerve."</p>
+
+<p>In other cases the placentas were parietal above, but axile at the base
+of the capsule, a striking instance of the facility with which axile
+placentation becomes parietal, the change being here effected by the
+prolongation of the axis, and the formation on it of a second whorl of
+carpellary leaves.</p>
+
+<p>In double flowers of <i>Primulace&aelig;</i> similar alterations in the
+placentation may often be observed. I have seen in <i>Primula sinensis</i>
+sutural, parietal, axile, and free central placentation all on the same
+plant; nay, even in the same capsule the ovules may be attached in
+various ways, and transitions from one form of placentation to another
+are not infrequent. The late Professor E. Forbes describes<a name="FNanchor_103_103" id="FNanchor_103_103"></a><a href="#Footnote_103_103" class="fnanchor">[103]</a> an
+instance of true foliar<span class='pagenum'><a name="Page_99" id="Page_99">[Pg 99]</a></span> and true axile placentation in the same flower
+in <i>Vinca minor</i>.</p>
+
+<p>These and many similar changes, which it is not necessary further to
+allude to, are not so much to be wondered at when it is borne in mind
+how slight an alteration suffices to produce a change in the mode of
+placentation, and how frequent is the production of adventitious buds or
+of foliar outgrowths, as may be seen in the sections relating to those
+subjects and to Substitutions.</p>
+
+<p>It will be remembered, also, how, in certain natural orders, under
+ordinary circumstances, considerable diversity in placentation exists,
+according as the margins of the carpels are merely valvate or are
+infolded so as to reach the centre. Often this diversity is due merely
+to the changes that take place during growth; thus, the placentation of
+<i>Caryophylle&aelig;</i>, <i>Cucurbitace&aelig;</i>, <i>Papaverace&aelig;</i>, and many other orders,
+varies according to the age of the carpel, and if any stasis or arrest
+of development occurs the placentation becomes altered accordingly.</p>
+
+<p>It is not necessary, in this place, to enter into the question whether
+the placenta is, in all cases whatsoever, a dependence of the axis, as
+Payer, Schleiden, and others, have maintained, or whether it be foliar
+in some cases, axial in others. This question must be decided by the
+organogenists; teratologically, however, there can be no doubt that
+ovules may be formed from both foliar and axial organs, and, moreover,
+that, owing to the variability above referred to, both in what are
+called natural and in what are deemed abnormal conditions, it can rarely
+happen that any safe inferences as to the normal or typical placentation
+of any family of plants can be drawn from exceptional or monstrous
+formations.</p>

+
+PROLIFICATION.</h4>
+
+
+<p>Moquin-Tandon and other writers have classed the production of buds in
+unwonted situations under the head of multiplication, but, as the
+altered arrangement is of graver import than the mere increase in
+number, it seems preferable to place these cases under this heading
+rather than under that of alterations of number.</p>
+
+<p>The adventitious bud may be a leaf-bud or a flower-bud; it may occupy
+the centre of a flower, thus terminating the axis, or it may be axillary
+to some or other of its component parts, or, again, it may be
+extra-floral. In this last case the prolification is of the
+inflorescence, and is hardly distinguishable from multiplication or
+subdivision of the common flower-stalk. In accordance with these
+differences we have median, axillary, and extra-floral prolification,
+each admitting of subdivision into a leafy or a floral variety,
+according to the nature of the adventitious bud. Under the head of each
+variety certain special peculiarities are noticed, but it may here be
+advisable to add a few general remarks on the subject.</p>
+
+<p>Axillary prolification is a much less frequent malformation<span class='pagenum'><a name="Page_101" id="Page_101">[Pg 101]</a></span> than the
+median form. If only the number of orders and genera be reckoned, the
+truth of this statement will be scarcely recognised; but if individual
+cases could be estimated, the difference in frequency between the two
+would be very much more obvious. This may, perhaps, be explained by the
+fact that the branch has a greater tendency to grow in length than it
+has to develop buds from the axils of the leaves. The flower is admitted
+to be homologous with the branch, and it is also known that, up to a
+certain time, the branch-bud or leaf-bud and the flower-bud do not
+essentially differ.<a name="FNanchor_104_104" id="FNanchor_104_104"></a><a href="#Footnote_104_104" class="fnanchor">[104]</a> At a later stage the difference between the two
+is manifested, not only in the altered form of the lateral organs in the
+flower-bud, but in the tendency to an arrest of growth, thus limiting
+the length of the central axial portion. Now, in prolified flowers the
+functions and, to a considerable extent, the appearance of a leaf-bud or
+of a branch are assumed, and with them the tendency to grow in length is
+developed. Median prolification, therefore, in this sense, is a further
+step in retrograde metamorphosis than is the axillary form. To grow in
+length, and to produce axillary buds, are alike attributes of the
+branch; but the former is much more frequently called into play than the
+latter; for the same reason, median prolification is more common than
+the axillary form. This is borne out by the frequency with which
+apostasis, or the separation of the floral whorls one from another, to a
+greater degree than usual, is met with in prolified flowers.</p>
+
+<p>In both forms the adventitious growth is much more frequently a
+flower-bud or an inflorescence than a leaf-bud or a branch. This may be
+due to the position of the flowers on a portion of the stem of the plant
+especially devoted to the formation of flower-buds, to the more or less
+complete exclusion of leaf-buds, <i>i.e.</i> on the inflorescence. This
+conjecture is borne out by the comparative rarity with which
+prolification has been observed in flowers that are solitary in the
+axils of the<span class='pagenum'><a name="Page_102" id="Page_102">[Pg 102]</a></span> ordinary leaves of the plant. If the lists of genera
+appended hereto be perused, it will be seen that nearly all the cases
+occur in genera where the inflorescence is distinctly separated from the
+other branches of the stem. In direct proportion, then, to the degree in
+which one region of the axis or certain branches of a plant are devoted
+to the formation of flower-buds to the exclusion of leaf-buds, is the
+frequency with which those flowers become affected with floral
+prolification.</p>
+
+<p>Flowers produced upon indefinite inflorescences are liable to be
+affected with either form of prolification more frequently than those
+borne upon definite inflorescences. Prolification in both varieties is
+also more frequently met with in branched inflorescences than in those
+in which the flowers are sessile; but the degree of branching seems less
+material, inasmuch as this malformation is more commonly recorded as
+occurring in racemes than in the more branched panicles, &amp;c. From the
+similar arrest of growth in length, in the case of the flower, to that
+which occurs in the stem in the case of definite inflorescence, it might
+have been expected that axillary prolification would be more frequent in
+plants having a cymose arrangement of their flowers than in those whose
+inflorescence is indefinite; such, however, is not the case. The reason
+for this may be sought for in the lengthening of the floral axis, so
+common in prolified flowers&mdash;a condition the reverse of that which
+happens in the case of definite inflorescence.</p>
+
+<p>Median prolification occurs frequently in double flowers; the axillary
+variety, on the other hand, is most common in flowers whose lateral
+organs have assumed more or less of the condition of leaves. The other
+coincident changes are alluded to elsewhere or do not present useful
+points of comparison, and may therefore be passed over.</p>
+
+
+
+<p><b>Prolification of the inflorescence.</b>&mdash;This consists in the formation of
+leaf-buds or of an undue number of flower-buds<span class='pagenum'><a name="Page_103" id="Page_103">[Pg 103]</a></span> on the inflorescence. It
+must be distinguished from virescence, or the mere green colour of the
+floral organs, and from chloranthy, in which all or the greater portion
+of the parts of the flower are replaced by leaves. Prolification is, in
+fact, a formation of supernumerary buds, leafy or floral, as the case
+may be, these buds being sessile or stalked, the ordinary buds being not
+necessarily changed. Prolification of the inflorescence, like the other
+varieties, admits of subdivision, not only according to the foliar or
+floral nature of the bud, but according to its position, terminal or
+median and lateral.</p>
+
+<p>Terminal prolification of the inflorescence, whether leafy or floral, is
+hardly to be looked upon in the light of a malformation<a name="FNanchor_105_105" id="FNanchor_105_105"></a><a href="#Footnote_105_105" class="fnanchor">[105]</a> seeing that
+a similar condition is so commonly met with normally, as in <i>Epacris</i>,
+<i>Metrosideros</i>, <i>Bromelia</i>, <i>Eucomis</i>, &amp;c., wherein the leafy axis
+projects beyond the inflorescence proper; or as in <i>Primula imperialis</i>,
+in which plant, as also in luxuriant forms of <i>P. sinensis</i>, tier after
+tier of flowers are placed in succession above the primary umbel.
+Nevertheless, when we meet with such conditions in plants which, under
+ordinary circumstances, do not manifest them, we must consider them as
+coming under the domain of teratology.</p>
+
+
+
+<p><b>Median foliar prolification of the inflorescence</b> is frequently met with
+in <i>Conifer&aelig;</i>, and has of late attracted unwonted attention from the
+researches of Caspary, Baillon, and others, on the morphology of these
+plants. The scales and bracts of the cone in these abnormal specimens
+frequently afford transitional forms of the greatest value in enabling
+morphologists to comprehend the real nature of the floral structure. It
+would be irrelevant here to enter into this subject; suffice it merely
+to say that an examination of very numerous specimens of this kind, in
+the common larch and in <i>Cryptomeria Japonica</i>, has enabled me to verify
+nearly the whole of Caspary's observations. A similar prolongation of
+the axis occurred in some of the male catkins of <i>Castanea</i><span class='pagenum'><a name="Page_104" id="Page_104">[Pg 104]</a></span> <i>vesca</i>,
+each of which had a tuft of small leaves at their extremity. In the
+common marigold and in <i>Lotus corniculatus</i> I have also seen instances
+of this kind. Kirschleger<a name="FNanchor_106_106" id="FNanchor_106_106"></a><a href="#Footnote_106_106" class="fnanchor">[106]</a> describes a tuft of leaves as occurring
+on the apex of the flowering spike after the maturation of the fruit in
+<i>Plantago</i>, and a similar growth frequently takes place in the common
+wallflower, in <i>Antirrhinum majus</i>, &amp;c. In cases where a renewal of
+growth in the axis of inflorescence has taken place after the ripening
+of the fruit, the French botanists use the term recrudescence, but the
+growth in question by no means always occurs after the ripening of the
+fruit, but frequently before. Professor Braun cites the case of a
+specimen of <i>Plantago lanceolata</i>, in which the spike was surmounted by
+a tuft of leaves and roots, as well as a still more singular instance in
+<i>Eryngium viviparum</i>, in which not only did particular branches
+terminate in rosettes of leaves provided with roots, but similar growths
+proceeded from the heads of flowers themselves. Baron de M&eacute;licoq<a name="FNanchor_107_107" id="FNanchor_107_107"></a><a href="#Footnote_107_107" class="fnanchor">[107]</a>
+gives a case in <i>Primula variabilis</i>, in which at the top of the
+flower-stalk, in the centre of six flowers, was placed a complete plant
+in miniature, having three leaves, from the axil of one of which
+proceeded a rudimentary flower. Mr. W. B. Jeffries also forwarded me a
+polyanthus (fig. 52) in which the peduncle was surmounted by a small
+plant, forming a crown above the ordinary flower-stalk, just as the
+crown of the pineapple surmounts that fruit. A similar instance was
+exhibited at the Scientific Committee of the Horticultural Society on
+July 11th, 1868, by Mr. Wilson Saunders; the species in this case was
+<i>P. cortusoides</i>. To Mr. R. Dean I am indebted for a similar proliferous
+cyclamen, which seems similar to one mentioned by Schlechtendal.<a name="FNanchor_108_108" id="FNanchor_108_108"></a><a href="#Footnote_108_108" class="fnanchor">[108]</a>
+This author alludes to an analogous circumstance in the inflorescence of
+<i>Cytisus nigricans</i>, where, however, the change was not<span class='pagenum'><a name="Page_105" id="Page_105">[Pg 105]</a></span> so great as in
+the preceding cases. The instances just cited all occur in plants having
+an indefinite form of inflorescence; but the production of a tuft of
+leaves or of a leafy shoot above or beyond the inflorescence is not
+confined to plants with this habit of growth, for Jacquin figures and
+describes an instance of this nature in the cymose flower-stems of a
+Sempervivum. "<i>Hi racemi</i>," says he, "<i>ultra flores producuntur in
+ramos, foliosos duo bifidos qui tandem trium unciarum longitudinem
+adepti fuerunt</i>."<a name="FNanchor_109_109" id="FNanchor_109_109"></a><a href="#Footnote_109_109" class="fnanchor">[109]</a></p>

+
+<p><b>Median floral prolification of the inflorescence</b>, wherein a new
+inflorescence projects beyond the primary one, is not uncommon in plants
+having their flowers arranged in close heads or umbels, as in the
+common<span class='pagenum'><a name="Page_106" id="Page_106">[Pg 106]</a></span> wild celery and other <i>Umbellifer&aelig;</i>.<a name="FNanchor_110_110" id="FNanchor_110_110"></a><a href="#Footnote_110_110" class="fnanchor">[110]</a> I have also met with
+it in <i>Trifolium repens</i>, in the umbellate variety of the common
+primrose, and in the scarlet geranium. Engelmann cites it in <i>Triticum
+repens</i>, Ro&euml;per in <i>Euphorbia palustris</i>.<a name="FNanchor_111_111" id="FNanchor_111_111"></a><a href="#Footnote_111_111" class="fnanchor">[111]</a></p>
+
+
+
+<p><b>Lateral foliar prolification of the inflorescence</b> is of more common
+occurrence than the preceding. I have met with it, amongst other plants,
+frequently in <i>Brassica oleracea</i>, <i>Pelargonium zonale</i>, <span class="smcap">Scabiosa</span>,
+<span class="smcap">Bellis</span>, and many other composites, also in <i>Leguminos&aelig;</i>, e.g. <i>Lupinus</i>,
+<i>Trifolium</i>, <i>Coronilla</i>, &amp;c. Prof. Oliver forwarded me a specimen of
+<i>Euphorbia geniculata</i> in which, in addition to other changes, there was
+a series of stalked buds bearing tufts of green scales, but without any
+trace of stamens or pistil; these adventitious buds occurred within the
+ordinary involucre of the plant, between it and the stamens. The pistil
+was unaffected in some cases, while in some others it was entirely
+wanting, the gynophore being surmounted by a cup-like involucre, divided
+into three acutely pointed lobes, each with a midrib; these encircled a
+series of stalked involucels, as before, and among which were scattered
+a few stamens, some perfect, others partially frondescent.</p>
+
+<p>In a specimen of <i>Scrophularia nodosa</i> examined by me one of the lateral
+buds on each of the cymes was represented, not by a flower, but by a
+tuft of leaves, the other buds being unchanged. As the inflorescence was
+much contracted in size, the appearance of the whole plant was greatly
+changed.</p>
+
+<p>Many of the instances of so-called viviparous plants, <i>e.g.</i>, <i>Polygonum
+viviparum</i>, may be cited under this head.<a name="FNanchor_112_112" id="FNanchor_112_112"></a><a href="#Footnote_112_112" class="fnanchor">[112]</a> Many species of <i>Allium</i>,
+<i>Lilium</i>, <i>Saxifraga</i>, <i>Begonia</i>, <i>Achimenes</i>, normally produce
+leaf-buds or bulbs in the inflorescence; so, too, leafy shoots are
+sometimes<span class='pagenum'><a name="Page_107" id="Page_107">[Pg 107]</a></span> found in <i>Alisma natans</i>, <i>Juncus uliginosus</i>, <i>Chlorophytum
+Sternbergianum</i>, &amp;c. As an accidental occurrence, a similar thing has
+been noticed in <i>Lychnis coronaria</i>, <i>Phaius grandifolius</i>, <i>Oncidium
+cebolleta</i>, <i>Epidendrum elongatum</i>,<a name="FNanchor_113_113" id="FNanchor_113_113"></a><a href="#Footnote_113_113" class="fnanchor">[113]</a> &amp;c. &amp;c.</p>
+
+<p>Here, too, may be mentioned those cases wherein a leaf-bud is found upon
+the surface of the so-called inferior ovary; generally a leaf only is
+found, but a leaf-bud may also originate in this situation, and in
+either case the inference is that the ovary is, in part at least, made
+of the dilated and hollowed axis. Leaves may occasionally be found in
+this way on the so-called calyx-tube or on the inferior ovaries of
+roses, pears, apples, <i>Pereskia</i>, <i>Crat&aelig;gus tanacetifolia</i>, &amp;c.</p>
+
+<p>The fruits of <i>Opuntia Salmania</i> and of <i>O. fragilis</i> ('Bull. Soc. Bot.
+France,' vol. i, p. 306; vol. v, p. 115) have been observed to form
+small fruit-like branches around their summits. This circumstance is
+more fully treated of in the succeeding chapter relating to Heterotaxy.</p>
+
+
+
+<p><b>Lateral floral prolification of the inflorescence.</b>&mdash;This, which is
+termed by Engelmann Ecblastesis foliorum sub floralium,<a name="FNanchor_114_114" id="FNanchor_114_114"></a><a href="#Footnote_114_114" class="fnanchor">[114]</a> is much the
+most common of all these deviations, and it is met with in every degree,
+from the presence of a single supernumerary flower in the axil of a
+bract to the existence of a small cluster or panicle of such flowers.</p>

+<p class="caption"> <span class="smcap">Fig.</span> 53.&mdash;Lateral prolification in inflorescence of <i>Pelargonium</i>.</p>
+</div>
+
+<p>It is common in the <i>Anemone coronaria</i> and <i>hortensis</i>, also in the
+common scarlet <i>Pelargonium</i> (fig. 53). It has been frequently recorded
+in <i>Poterium sanguisorba</i>, and in <i>Sanguisorba officinalis</i>, and is
+especially common in <i>Umbellifer&aelig;</i>, <i><ins title="Dipsace&aelig; in original">Dipsacace&aelig;</ins></i>, and <i>Composit&aelig;</i>; a
+familiar illustration in the latter order is afforded by the
+hen-and-chicken daisy. In some species of Composit&aelig;, indeed,<span class='pagenum'><a name="Page_108" id="Page_108">[Pg 108]</a></span> it is a
+normal and constant occurrence, while in other cases, such as <i>Filago
+germanica</i>, usually described as proliferous, there is not, strictly
+speaking, any prolification, for the branching of the stalk takes place
+below the inflorescence, and the branches originate from the axils of
+ordinary leaves, not from the floral leaves or bracts. <i>Convolvulus
+Sepium</i> is very commonly subject to the production of flower-buds from
+the axils of the floral leaves. The several species of Plantain
+(<i>Plantago</i>) seem very liable to this and similar changes.
+Schlechtendal<a name="FNanchor_115_115" id="FNanchor_115_115"></a><a href="#Footnote_115_115" class="fnanchor">[115]</a> gives a summary of the various kinds of malformation
+affecting the inflorescence in <i>Plantago</i>, and divides them into five
+groups, as follows:&mdash;1st, bracteate, wherein the inferior bracts are
+quite leaf-like, as is frequently seen in <i>Plantago major</i>. 2nd,
+roseate; bracts leafy in tufts or rosettes, without flowers, as in the
+so-called rose plantain, common in old-fashioned gardens in this
+country. 3rd, polystachyate; spike-branched, bearing other spikes in the
+axils of the bracts, as in <i>P. lanceolata</i>, <i>P. maritima</i>, &amp;c. 4th,
+proliferous, where the flower-stalk bears a rosette, a spike, or a<span class='pagenum'><a name="Page_109" id="Page_109">[Pg 109]</a></span> head
+with other rosettes. 5th, paniculate, in which the inflorescence has
+become a much-branched pyramidal panicle, covered with little bracts,
+and with very rudimentary flowers.<a name="FNanchor_116_116" id="FNanchor_116_116"></a><a href="#Footnote_116_116" class="fnanchor">[116]</a> The first two groups belong
+rather to frondescence of the bracts; but with regard to the whole of
+them it will easily be surmised that intermediate forms occur, linking
+one group to the other, and defying exact allocation in either. Thus, in
+the borders of richly cultivated fields in the neighbourhood of London I
+have frequently gathered specimens of <i>Plantago major</i> with a branched
+spike provided with large leafy bracts, the branches of the spike being
+but little less in diameter than the ordinary single spike. These
+specimens would therefore seem to be intermediate between
+Schlechtendal's bracteate and polystachyate divisions. Wigand<a name="FNanchor_117_117" id="FNanchor_117_117"></a><a href="#Footnote_117_117" class="fnanchor">[117]</a> also
+describes an anomalous specimen of <i>Plantago major</i> similar to those
+just mentioned, but having small lateral spikes in place of large ones.
+The instance quoted from Professor Braun would fall under the roseate
+section, as would also that of Kirschleger, though we are expressly told
+that the tuft of leaves in this last case was not developed until after
+the ripening of the seed-vessel. One of the characters of the roseate
+group, according to Schlechtendal, is the absence of flowers, but most
+persons who have had the opportunity of<span class='pagenum'><a name="Page_110" id="Page_110">[Pg 110]</a></span> watching the growth of the rose
+plantain must have observed the occasional production of flowers,
+sometimes stalked, in the axils of the leafy bracts, and at the same
+time have noticed that the internodes become elongated, so that an
+approach is made to the ordinary spike-like form of the inflorescence.
+The proliferous group would include such specimens as that of <i>P.
+lanceolata</i><span class='pagenum'><a name="Page_111" id="Page_111">[Pg 111]</a></span> mentioned by Dr. Johnston,<a name="FNanchor_118_118" id="FNanchor_118_118"></a><a href="#Footnote_118_118" class="fnanchor">[118]</a> wherein were several
+spikes, some sessile, others stalked and pendent, the whole intermixed
+with leaves and disposed in a rose-like manner. I have myself gathered
+specimens of this nature, occurring in the same plant, at Shanklin, Isle
+of Wight (fig. 56).</p>

+of the axile organs. Branched spikes of this character are not so common
+among Orchids as might be expected.<span class='pagenum'><a name="Page_113" id="Page_113">[Pg 113]</a></span> Professor Reichenbach enumerates a
+few instances in the Report of the International Botanical Congress of
+London, 1866, p. 121, and the same author gives an illustration in his
+'Orchidographia Europ&oelig;a,' tab. 150.</p>
+
+<p>In Grasses, as indeed in other plants with a spicate inflorescence, this
+change occurs not unfrequently. The common Ray Grass (<i>Lolium</i>) is
+especially subject to the change in question, and among cultivated
+cereals, maize and wheat occasionally show this tendency to subdivision.

+<p><b>Prolification of the flower.</b>&mdash;In the preceding sections the formation of
+adventitious buds of a leafy or floral nature on the inflorescence has
+been considered. A similar production of buds may take place in the
+flower itself,<span class='pagenum'><a name="Page_116" id="Page_116">[Pg 116]</a></span> either from its centre or from the axil of some of its
+constituent parts. Prolification of the flower is therefore median or
+axillary, and the adventitious bud itself may be of a leafy or a floral
+nature.</p>
+
+
+
+<p><b>Median leafy prolification.</b>&mdash;In this malformation the centre of the
+flower is occupied by a bud or a branch; the growing point or
+termination of the axis which ordinarily ceases to grow after the
+formation of the carpels, takes on new growth. This is well shown in the
+accompanying illustration (fig. 58), representing the thalamus of a
+strawberry prolonged beyond the fruits into a small leaf-bearing branch.</p>

+</div>
+
+<p>In other cases the carpels are entirely absent and their place is
+supplied by a leafy shoot as in a species of <i>Verbascum</i>, which came
+under my own observation. In this case the petals were virescent, and
+the stamens and pistils were entirely absent, hence in truth, the
+so-called<span class='pagenum'><a name="Page_117" id="Page_117">[Pg 117]</a></span> flower more nearly resembled a branch. In a flower of a May
+Duke cherry, for which I am indebted to Mr. Salter, there was a gradual
+change from the floral to the foliar condition; thus there were five
+distinct lanceolate sepals, the arrangement of whose veins betokened
+that they were leaf-sheaths rather than perfect leaves, ten petals
+partly foliaceous and sheath-like as to their venation, one of them
+funnel-shaped, but whether from dilatation or cohesion of the margins
+could not be determined. The stamens were eight or ten in number, their
+connectives prolonged into foliaceous or petaloid appendages, so that
+the filament represented the stalk of the leaf. The pistil was entirely
+absent and its place was supplied by a branch with numerous perfectly
+formed stipulate leaves.</p>
+
+<p>Some flowers of <i>Anagallis arvensis</i> described by Dr. Marchand<a name="FNanchor_119_119" id="FNanchor_119_119"></a><a href="#Footnote_119_119" class="fnanchor">[119]</a> are
+so interesting and show so well the gradual stages by which this
+malformation is arrived at, that it is desirable to cite the summary of
+Dr. Marchand's researches as given in the 'Gardeners' Chronicle' by Mr.
+Berkeley, taking that instance first in which the parts of the flower
+departed least from the normal condition, and then the others in their
+proper order. In all the parts there was a greater or less tendency to
+assume a green tint; in some they were entirely green, in others the
+brighter colours were confined to the more recently developed parts.</p>
+
+<p>"1. In the first case then, the sepals and petals were in their normal
+position, though rather more dilated than usual; the anthers were
+fertile, the principal change existing in the ovary, the upper part of
+which was wanting, so that the ovules were exposed seated on the central
+placenta.</p>
+
+<p>2. In the next step the calyx, more developed than usual, was separated
+from the corolla by a long peduncle, and the ovary, which was ovate,
+contained instead of a placenta a sort of plumule or young shoot.</p><p><span class='pagenum'><a name="Page_118" id="Page_118">[Pg 118]</a></span></p>
+
+<p>3. In this case the corolla and calyx were distant from each other;
+there was no trace of stamens, but the axis was continued from the
+centre of the corolla, and ended in a leaf-bud.</p>
+
+<p>4. The calyx and corolla nearly as before, but instead of stamens a
+whorl of little leaves was developed, in the centre of which the axis
+was continued, bearing at its tip two whorls of leaflets, alternately
+three and three.</p>
+
+<p>5. In this case two out of the five stamens were normal, the other three
+changed into leaves, showing clearly the origin of the leaflets, in the
+last case, which took the place of the stamens.</p>
+
+<p>6. The ovary varied in different flowers. In some the placenta was
+crowned with ovules; in others the ovules were replaced by a single
+whorl of leaflets; in others there was every shade of change from
+ordinary ovules to perfect leaflets; while in others, again, every ovule
+was converted into a leaf with a long petiole.</p>
+
+<p>7. In these flowers shoots were developed in the axils of the sepals, or
+on the face of the petals between the point of their insertion and that
+of the stamens, and, what is most curious, in the interior of the
+ovaries round the foot of the placenta.</p>
+
+<p>8. Here, again, a very singular condition presented itself: the calyx
+and corolla separated from each other, the stamens partly developed, the
+axis continued beyond the corolla, branched and bearing normal leaves so
+as exactly to resemble an ordinary stem, while in consequence of the
+calyx and corolla being bent down to the ground, adventitious roots were
+developed from the axis on the under side above each of them. In another
+case, where the calyx and corolla were approximated, the ovary was open
+above, and sent out six shoots from within, perfectly developed, clearly
+representing the central placenta and five axile buds, and each giving
+out a number of adventitious roots at its base."</p>
+
+<p>In other genera of the same order (<i>Primulace&aelig;</i>) an<span class='pagenum'><a name="Page_119" id="Page_119">[Pg 119]</a></span> extension of the
+placenta into a leafy branch has been observed, as in <i>Lysimachia</i>,
+where in one case the prolonged placenta was removed and struck as a
+cutting.<a name="FNanchor_120_120" id="FNanchor_120_120"></a><a href="#Footnote_120_120" class="fnanchor">[120]</a></p>
+
+<p>In <i>Ericace&aelig;</i> too, the axile placenta has been seen ovuliferous at the
+base and prolonged above into a leafy branch.<a name="FNanchor_121_121" id="FNanchor_121_121"></a><a href="#Footnote_121_121" class="fnanchor">[121]</a></p>
+
+
+
+<p><b>Median floral prolification.</b>&mdash;This is of more frequent occurrence than
+the preceding. The prolonged axis is more frequently terminated by a
+flower-bud than by a leaf-bud, though it must be remarked, that the
+lengthened and protruded stem frequently bears leaves upon its sides,
+even if it terminate in a flower, and thus the new growth partakes of a
+mixed leafy and floral nature. Instances of this kind have long been
+familiar to observers, and have always excited attention from the
+singularity of their appearance. In one of the old stained-glass
+windows, apparently of Dutch manufacture, in the Bodleian Picture
+Gallery at Oxford, is a representation of a <i>Ranunculus</i> affected with
+median floral prolification.<a name="FNanchor_122_122" id="FNanchor_122_122"></a><a href="#Footnote_122_122" class="fnanchor">[122]</a> In pinks the affection is not
+unfrequently met with. Fig. 60 shows an instance of the kind copied from
+Schotterbec.</p>
+
+<p>A singular instance of prolification in the central flower of one of the
+verticillasters of <i>Phlomis fruticosa</i> fell under my own notice; it was
+a case wherein the calyx was torn on one side, and one of its lobes had
+become petaloid. Between the calyx and the corolla were three or four
+spathulate, hairy, bract-like organs; the corolla and stamens were
+unchanged; but in place of the usual four-lobed ovary there was a single
+carpel with a basilar style, terminated by a forked stigma. Occupying
+the place of the other lobes of the pistil was an oblong woolly
+flower-bud, consisting of calyx, corolla, and stamens, but with no trace
+of pistil. I<span class='pagenum'><a name="Page_120" id="Page_120">[Pg 120]</a></span> have been unable to find recorded any instance of
+malformation among Labiates or Borages at all similar to this. It
+differed from most other examples of prolification in that the axis was
+not prolonged, the adventitious bud occupying precisely the position of
+the three lobes of the ovary that were absent. The sole remaining carpel
+had a style and a stigma as perfect in appearance as though the pistil
+had been complete.</p>

+<p class="caption"> <span class="smcap">Fig.</span> 60.&mdash;Flower of <i>Dianthus</i> affected with median floral prolification.</p>
+</div>
+
+<p>In a flower of <i>Conostephium</i> (<i>Epacridace&aelig;</i>) forwarded to me by Mr.
+Bentham, there was a similar adventitious bud placed by the side of the
+pistil, but as the latter contained the usual number of cells it is
+probable that the supernumerary bud in this case originated rather from
+the side than the end of the axis.</p>
+
+<p>Certain families of plants present this deviation from their ordinary
+structure with greater frequency than others: the following orders seem
+to be the most frequently affected by it: <i>Ranunculace&aelig;</i>,
+<i>Caryophyllace&aelig;</i>,<span class='pagenum'><a name="Page_121" id="Page_121">[Pg 121]</a></span> <i>Rosace&aelig;</i>; while it is commonly met with in
+<i>Scrophulariace&aelig;</i>, <i>Primulace&aelig;</i> and <i>Umbellifer&aelig;</i>. Of genera which seem
+peculiarly liable to it may be mentioned the following: <i>Anemone</i>,
+<i>Ranunculus</i>, <i>Cheiranthus</i>, <i>Dianthus</i>, <i>Dictamnus</i>, <i>Daucus</i>, <i>Rosa</i>,
+<i>Geum</i>, <i>Pyrus</i>, <i>Trifolium</i>, <i>Antirrhinum</i>, <i>Digitalis</i>, <i>Primula</i>.</p>
+
+<p>A reference to the subjoined list of genera affected by this
+malformation, and the knowledge of its comparatively greater frequency
+in some than in others of them, will show that it is more often met with
+in plants having an indefinite form of inflorescence than in those
+having a definite one. The change may affect some only, or the whole of
+the flowers constituting an inflorescence; and though it is by no means
+a constant occurrence, it very frequently happens that the central or
+terminal flower in a definite inflorescence is alone affected, the
+others remaining in their ordinary condition, as in pinks (<i>Dianthus</i>);
+and in the indefinite forms of inflorescence, it is equally common that
+the uppermost flower or flowers are the most liable to be thus affected.</p>
+
+<p>In those plants which present this deviation from the ordinary condition
+with the greatest frequency, it often happens that the axis is normally
+more or less prolonged, either between the various whorls of the flower,
+as in the case of the gynophore, &amp;c., or into the cavity of the carpels,
+as in the instances of free central placentation. To bear out this
+assertion, the following instances taken from those genera having
+definite inflorescence, and which are very commonly affected with
+prolification, may be cited; thus, in <i>Anemone</i> and <i>Ranunculus</i> the
+thalamus is prolonged to bear the numerous carpels; in <i>Dianthus</i> there
+is a marked internode separating the carpels from the other parts of the
+flower; in <i>Primulace&aelig;</i> central prolification is very common, and this
+is one of the orders where the placenta seems from the researches of
+Duchartre and others, to be truly a production of the axis within the
+carpels;<a name="FNanchor_123_123" id="FNanchor_123_123"></a><a href="#Footnote_123_123" class="fnanchor">[123]</a> in <i>Thesium</i> also, another genus with<span class='pagenum'><a name="Page_122" id="Page_122">[Pg 122]</a></span> free central
+placenta, this malformation has been found.</p>
+
+<p>So also among plants with indefinite inflorescence, prolification seems
+very frequently to affect those wherein the axis is normally prolonged;
+thus it is common in <i>Dictamnus</i>, which plant has an internode
+supporting the pistil; it is frequent among <i>Umbellifer&aelig;</i>, where the
+carpophore may be truly considered an axile production; it is common
+among <i>Rosace&aelig;</i> and <i>Ranunculace&aelig;</i>, in many of which the axis or
+thalamus is well-marked, and it is by no means infrequent in the flowers
+of the Orange, where the floral internodes are also slightly elongated;
+on the other hand, there is no case on record in <i>Magnoliace&aelig;</i>, and some
+other orders where the floral part of the axis is at some point or other
+elongated; still, on the whole, there can be but little doubt that there
+is a real relation between prolification and the normal extension of the
+floral internodes.</p>
+
+<p>Under these circumstances, those instances wherein the parts of the
+flower become separated one from the other by the elongation of the
+internodes (apostatis), constitute a lesser degree of the same change,
+which operates most completely in the formation of a new bud at the
+extremity of the prolonged axis. Some specimens of <i>Geum rivale</i> (a
+plant very liable to become prolified) in my possession show this very
+clearly. In the wild plant the thalamus is elevated on a short stalk; in
+the abnormal ones the thalamus is simply upon a longer stalk than usual,
+or in a more advanced stage of the deviation the lengthened thalamus
+takes the form of a branch provided with leaves and terminated by a
+flower; it is noticeable, also, in these specimens, that the sepals of
+the lower flower have assumed entirely the dimensions and appearance of
+leaves.</p>
+
+<p>Median prolification has occasionally been recorded in flowers that
+have, in their ordinary condition, but one carpel, as in <i>Leguminos&aelig;</i>
+and in <i>Santalace&aelig;</i>. In <i>Leguminos&aelig;</i>, as also in <i>Amygdalus</i>, it would
+seem as if<span class='pagenum'><a name="Page_123" id="Page_123">[Pg 123]</a></span> the adventitious bud were strictly a lateral and axillary
+production, and moreover that the carpel itself is not strictly terminal
+but lateral in position, though apparently terminal from the abortion of
+other carpels. In the only recorded instance that I am aware of, of this
+malformation affecting the genus <i>Thesium</i>, the pistil was altogether
+absent, and occupying its place was the new bud or branch.<a name="FNanchor_124_124" id="FNanchor_124_124"></a><a href="#Footnote_124_124" class="fnanchor">[124]</a></p>

+
+<p>As the carpels are not unfrequently absent in cases of median
+prolification, it has been thought that the pistil in such cases was
+metamorphosed into a stem bearing leaves or flowers. Setting aside the
+physiological difficulties in the way of accepting such an opinion, an
+examination of any number of cases is sufficient to refute it; for, as
+Moquin well remarks, the carpels may frequently be found either in an
+unaltered condition or more or less modified.</p>
+
+<p>If the pistil be normally syncarpous, its constituent carpels, if
+present at all in the prolified flower, become disjoined one from the
+other to allow of the passage between them of the prolonged axis; thus
+in some malformed flowers of <i>Daucus Carota</i> gathered in Switzerland
+(fig. 61), not only was the calyx partially detached from the pistil,
+but the carpels themselves were leaf-like, disjoined, and unprovided
+with ovules; between them rose a central prolongation of the axis, which
+almost immediately divided into two branches, each terminated by a small
+umbel of perfect flowers, surrounded by minute bracts.<a name="FNanchor_125_125" id="FNanchor_125_125"></a><a href="#Footnote_125_125" class="fnanchor">[125]</a></p><p><span class='pagenum'><a name="Page_125" id="Page_125">[Pg 125]</a></span></p>
+
+<p>Not only are the carpels thus frequently separated one from the other by
+the prolonged axis, but they undergo commonly a still further change in
+becoming more or less completely foliaceous, as in the <i>Daucus</i> just
+mentioned, where the carpels were prolonged into two lance-shaped
+leaves, whose margins in some cases were slightly incurved at the apex,
+forcibly calling to mind the long "beaks" that some Umbelliferous genera
+have terminating their fruits&mdash;for instance, <i>Scandix</i>. Dr. Norman, in
+the fourth series of the 'Annales des Sciences,' vol. ix, has described
+a prolification of the flower of <i>Anchusa ochroleuca</i>, in which the
+pistil consisted of two leaves, situated antero-posteriorly on a long
+internode, with a small terminal flower-bud between them; and numerous
+similar instances might be cited.</p>
+
+<p>In this place may also be noticed those instances wherein the placenta
+elongates so much that the pericarp becomes ruptured to allow of the
+protrusion of the placenta, although this prolongation is not attended
+by the formation of new buds. Cases of this kind occurring in
+<i>Melastoma</i> and <i>Solanum</i> have been put on record by M. Alph. de
+Candolle.<a name="FNanchor_126_126" id="FNanchor_126_126"></a><a href="#Footnote_126_126" class="fnanchor">[126]</a> This is a change analogous with that which occurs in some
+species of <i>Leontice</i> or <i>Caulophyllum</i>, as commented on by Robert
+Brown. See 'Miscellaneous Botanical Works' of this author, Ray Society,
+vol. i, p. 359.</p>
+
+<p>If the pistil be apocarpous, and the carpels arranged spirally on an
+elevated thalamus, it then frequently happens that the carpels,
+especially the upper ones,<span class='pagenum'><a name="Page_126" id="Page_126">[Pg 126]</a></span> become carried up with the prolonged axis,
+more widely separated one from the other than below, and particularly
+liable to undergo various petalloid or foliaceous changes as in
+proliferous <i>Roses</i>, <i>Potentilla</i>, &amp;c.</p>

+</div>
+
+<p>Fig. 62, copied from Cramer, shows an instance of this kind in
+<i>Delphinium elatum</i>, where not only is the thalamus prolonged, and the
+carpels separated, but from the axils of some of the latter which have<span class='pagenum'><a name="Page_127" id="Page_127">[Pg 127]</a></span>
+assumed from the disunion of their margins somewhat of the appearance of
+leaves, other flowering branches proceed&mdash;axillary prolification. If, on
+the other hand, the carpels be few in number, and placed in a
+verticillate manner, the axis then generally passes upwards without any
+change in the form or position of the carpels being apparent, as in a
+proliferous columbine, figured in the 'Linnean Transactions,' vol.
+xxiii, tab. 34, fig. 5.</p>
+
+<p>When a flower with the ovary naturally inferior or adherent to the calyx
+becomes prolified, a change in the relative position of the calyx and
+ovary almost necessarily takes place, the latter becoming superior or
+detached from the calyx; this has been already alluded to in
+<i>Umbellifer&aelig;</i>. In a species of <i>Campanula</i> examined by me, the calyx was
+free, the corolla double, the stamens with petaloid filaments, and in
+the place of the pistil there was a bud consisting of several series of
+green bracts, arranged in threes, and enclosing quite in the centre
+three carpellary leaves detached from one another and the other parts of
+the flower, and open along their margins, where the ovules were placed.
+In other similar instances in the same species of <i>Campanula</i>, the
+styles were present, forming below an imperfect tube which surrounded
+the adventitious bud; in another, contrary to what occurs usually in
+such cases, the ovary was present in its usual position, but surmounted
+by a bud of leafy scales, enclosed within the base of a tube formed by
+the union of the styles. A similar relative change in the position of
+the calyx and the ovary takes place when the <i>Composit&aelig;</i> are affected
+with central prolification, or even in that lesser degree of change
+which merely consists in the separation and disunion of the parts of the
+flower, but which in these flowers appear to be, as it were, the first
+stage towards prolification. I owe to the kindness of Professor Oliver a
+sketch of a species of <i>Rudbeckia</i>? showing this detachment of the calyx
+from the ovary. In a monstrous <i>Fuchsia</i> that I have had the opportunity
+of recently examining, the calyx was<span class='pagenum'><a name="Page_128" id="Page_128">[Pg 128]</a></span> similarly detached from the ovary
+simultaneously with the extension of the axis. Here the petals were
+increased in number and variously modified, the stamens also; while in
+the centre and at the top of the flower, conjoined at the base with some
+imperfect stamens, was a carpel open along its ovuliferous margins. Such
+instances as these seem to be the first stages of a change which,
+carried out more perfectly, would result in the formation of a new bud
+on the extremity of the prolonged axis.</p>
+
+<p>In <i>Orchidace&aelig;</i>, among which family I have now met with several
+instances of prolification, the ovary seems usually to be absent. Fig.
+63 shows a prolified flower of <i>Orchis pyramidalis</i> in which the
+perianth was nearly regular, the central portions of the flower absent,
+and their place supplied by a new miniature raceme. This specimen was
+forwarded to me by Dr. Moore, of Glasnevin.</p>

+</div>
+
+<p>As might be expected, it very rarely happens that median prolification
+occurs without some other deviation in one or more parts of the flower
+being simultaneously manifested. Some of these changes have been already
+mentioned, but others are commonly met with, as, for instance, the
+multiplication or doubling, as it is termed, of the petals; others,
+though less frequent, are of more<span class='pagenum'><a name="Page_129" id="Page_129">[Pg 129]</a></span> interest. Fusion of two or more
+flowers in association with prolification is especially common in
+cultivated specimens of <i>Digitalis purpurea</i>; the uppermost flowers of
+the raceme become fused together so as to form one large, regular,
+erect, cup-shaped corolla, to the tube of which the stamens are
+attached, in greater number than ordinary, and all of equal length; the
+bracts and sepals are confusedly arranged on the exterior of the flower;
+while in the centre, in the place usually occupied by the pistil, there
+rises a conical prolongation of the axis, bearing at its outer or lower
+portion a number of open carpels, provided, it may be, with styles and
+ovules; these enclose an inner series of scale-like bracts, from whose
+axils proceed more or less perfect florets; so that in the most highly
+developed stage a perfect raceme of flowers may be seen to spring from
+the centre of a cup-shaped regular flower, whose lobes show its compound
+character. All intermediate stages of this malformation may be found
+from cases where there is a simple fusion of two flowers with a second
+verticil of carpels within the outer, up to such cases as those which
+have been just mentioned. It is worthy of special remark, that in all
+these cases the flowers at the uppermost part of the raceme are alone
+affected, and that, in addition to the prolification, there is fusion of
+two or more flowers, and regularity in the form of the compound corolla
+and stamens.</p>
+
+<p>The calyx of a prolified flower is either unchanged, or it is modified
+in harmony with the changes in the central part of the flower. If the
+ovary be normally superior or free from the calyx, then the latter is
+comparatively rarely altered; for instance, in proliferous pinks
+(<i>Dianthus</i>) the calyx is seldom affected, except, indeed, in those
+instances where the floral axis is prolonged, and produces from its side
+a successive series of sepals, as in what is called the wheat-ear
+carnation; but though these instances may be, as I believe, an imperfect
+degree of prolification, they do not affect the general truth of the
+above opinion, that the calyx, if it be free<span class='pagenum'><a name="Page_130" id="Page_130">[Pg 130]</a></span> from the ovary, is but
+rarely changed in a prolified flower; but that this is not a universal
+rule is shown by proliferous flowers of <i>Geum rivale</i>, where the sepals
+are usually large and leaf-like, as they likewise are frequently in
+proliferous roses and pears.</p>
+

+<p class="caption"> <span class="smcap">Fig.</span> 64.&mdash;Proliferous rose. Hip absent, sepals leafy, stamens wanting, axis prolonged bearing supplementary flower, &amp;c. (Bell Salter).</p>
+</div>
+
+<p>Proliferous roses have a special interest, inasmuch as they show very
+conclusively that the so-called calyx-tube of these plants is merely a
+concave and inverted thalamus, which, in prolified specimens, becomes
+elongated<span class='pagenum'><a name="Page_131" id="Page_131">[Pg 131]</a></span> (fig. 64) after the fashion of <i>Geum rivale</i>, &amp;c.<a name="FNanchor_127_127" id="FNanchor_127_127"></a><a href="#Footnote_127_127" class="fnanchor">[127]</a>
+Occasionally from the middle of the outer surface of the urn-shaped
+thalamus proceeds a perfect leaf, which could hardly be produced from
+the united sepals or calyx-tube; a similar occurrence in a pear is
+figured in Keith's 'Physiological Botany,' plate ix, fig. 12.</p>
+
+<p>The change which the calyx undergoes when flowers with an habitually
+adherent ovary become prolified, and wherein the calyx is disjoined from
+the ovary, has been before mentioned, but it may also be stated that,
+under such circumstances, the constituent sepals are frequently
+separated one from the other, and not rarely assume more or less of the
+appearance of leaves, as in proliferous flowers of <i>Umbellifer&aelig;</i>,
+<i>Campanulace&aelig;</i>, <i>Composit&aelig;</i>, &amp;c.</p>
+
+<p>As to the corolla, it was long since noticed that prolification was
+especially liable to occur in double flowers; indeed, Dr. Hill, who
+published a treatise on this subject, setting forth the method of
+artificially producing prolified flowers, deemed the doubling to be an
+almost necessary precursor of prolification;<a name="FNanchor_128_128" id="FNanchor_128_128"></a><a href="#Footnote_128_128" class="fnanchor">[128]</a> but, though frequently
+so, it is not invariably the case that the flower so affected is
+double&mdash;<i>e.g.</i> <i>Geum</i>. If double, the doubling may arise from actual
+multiplication of the petals, or from the substitution of petals for
+stamens and pistils, according to the particular plant affected.
+Occasionally in prolified flowers the parts of the corolla, like those
+of the calyx, become foliaceous, and in the case of proliferous pears
+fleshy and succulent. There is in cultivation a kind of <i>Cheiranthus</i>?
+in which there is a constant repetition of the calyx and corolla,
+conjoined with an entire absence of the stamens and pistils; a short
+internode separates each flower from the one above it, and thus
+frequently<span class='pagenum'><a name="Page_132" id="Page_132">[Pg 132]</a></span> ten or a dozen of these imperfect flowers may be seen on the
+end of a flower-stalk, giving an appearance as if they were strung like
+beads, at regular intervals, on a common stalk. I have seen a similar
+instance in a less degree in a species of <i>Helianthemum</i>.</p>
+
+<p>The stamens are subject to various changes in prolified flowers; they
+assume, for instance, a leaf-like or petal-like condition, or take on
+them more or less of a carpellary form, or they may be entirely absent;
+but none of these changes seem to be at all necessarily connected with
+the proliferous state of the flower. Of more interest is the alteration
+in the position of these organs which sometimes necessarily accrues from
+the elongation of the axis and the disjunction of the calyx; thus, in
+proliferous roses the stamens become strictly hypogynous, instead of
+remaining perigynous. In <i>Umbellifer&aelig;</i> the epigynous condition is
+changed for the perigynous, &amp;c.</p>
+
+<p>The condition of the pistillary organs in prolified flowers has already
+been alluded to. Hitherto those instances have been considered in which
+either the carpels were absent, or the new bud proceeded from between
+the carpels. There is also an interesting class of cases where the
+prolification is strictly intra-carpellary; the axis is so slightly
+prolonged that it does not protrude beyond the carpels, does not
+separate them in any way, but is wholly enclosed within their cavity.
+Doubtless, in many cases, this is merely a less perfect development of
+that change in which the axis protrudes beyond the carpels. This
+intra-carpellary prolification occurs most frequently in plants having a
+free central placenta, though it is not confined to them, as it is
+recorded among <i>Boragine&aelig;</i>. A remarkable instance of this is described
+by Mr. H. C. Watson in the first volume of Henfrey's 'Botanical
+Gazette,' p. 88. In this specimen a raceme of small flowers was included
+within the enlarged pericarp of a species of <i>Anchusa</i>. But the most
+curious instances of<span class='pagenum'><a name="Page_133" id="Page_133">[Pg 133]</a></span> this form of prolification are, no doubt, those
+which are met with among <i>Primulace&aelig;</i> and other orders with free central
+placentation.</p>
+
+<p>Duchartre, in his memoir on the organogeny of plants with a free central
+placenta, in the 'Ann. des Sc. Nat.,' 3 s&eacute;r., 1844, p. 290, among other
+similar instances, mentions two flowers of <i>Cortusa Matthioli</i>, wherein
+the placenta was ovuliferous at the base; but the upper portion, instead
+of simply elongating itself into a sterile cone, had produced a little
+flower with its parts slightly different from those of the normal
+flowers. M. Alph. de Candolle has likewise described somewhat similar
+deviations, and one in particular in <i>Primula Auricula</i>, where the
+elongated placenta gave off long and dilated funiculi bearing ovules,
+while other funiculi were destitute of these bodies, but were much
+dilated and foliaceous in appearance.<a name="FNanchor_129_129" id="FNanchor_129_129"></a><a href="#Footnote_129_129" class="fnanchor">[129]</a> In some flowers of
+<i>Rhododendron</i> I have observed a similar condition of the ovules, which,
+moreover, in the primary flowers, were attached to the walls of the
+carpels&mdash;parietal placentation.</p>
+
+<p>In speaking of these as cases of intra-carpellary prolification, it is,
+of course, impossible to overlook the fact that they differ in degree
+only from those cases where the lengthened axis projects beyond the
+cavity of the carpels; nevertheless they seem to demand special notice,
+because in these particular plants the placenta or its prolongation
+appears never to protrude beyond the carpels, or at least very rarely.
+There are, however, numerous instances of such an extension of the
+placenta and of prolification occurring among <i>Primulace&aelig;</i> in
+conjunction with the more or less complete arrest of growth of the
+carpels.<a name="FNanchor_130_130" id="FNanchor_130_130"></a><a href="#Footnote_130_130" class="fnanchor">[130]</a> An instance of this kind has come under my own notice in a
+monstrosity of the chinese primrose, in which the carpels were reduced
+to a hardly discernible rim<span class='pagenum'><a name="Page_134" id="Page_134">[Pg 134]</a></span> surrounding an umbel of five rays, each
+terminated by a small normally constituted flower-bud.</p>
+
+<p>The ovules of a prolified flower are either unaffected, or they occur in
+a rudimentary form, or, lastly, they may be present in the guise of
+small leaves.</p>
+
+<p>Under the term prolification of the fruit two or three distinct kinds of
+malformation appear to have been included. The term seems usually to be
+applied to those cases where from the centre of one fruit a branch
+bearing leaves, flowers, or another fruit, is seen to project, as
+happens occasionally in pears. Now, in many instances, not only the
+fruit, is repeated, but also the outer portions of the flower, which
+wither and fall away as the adventitious fruit ripens; so that at length
+the phenomenon of one fruit projecting from another is produced. It is
+obvious that this form of prolification in no wise differs from ordinary
+central prolification. Sometimes some of the whorls of the adventitious
+flower are suppressed; thus, M. Duchartre describes some orange blossoms
+as presenting alternating series of stamens and pistils one above
+another, while the calyces and corollas belonging to each series of
+stamens and pistils were entirely suppressed.<a name="FNanchor_131_131" id="FNanchor_131_131"></a><a href="#Footnote_131_131" class="fnanchor">[131]</a> In other cases,
+doubtless, the carpellary whorl is alone repeated, the other whorls of
+the adventitious flower being completely absent.</p>
+
+<p>Another condition, apparently sometimes mistaken for prolification of
+the fruit, is that in which the carpellary whorl becomes multiplied; so
+that there is a second or even a third series within the outer whorl of
+carpels. If the axis be at all prolonged, then these whorls are
+separated one from the other, and produce in this way an appearance of
+prolification. This happens frequently in oranges, as in the variety
+called Mellarose.<a name="FNanchor_132_132" id="FNanchor_132_132"></a><a href="#Footnote_132_132" class="fnanchor">[132]</a></p><p><span class='pagenum'><a name="Page_135" id="Page_135">[Pg 135]</a></span></p>
+
+<p>Moquin has given an explanation of the St. Valery Apples, wherein the
+petals are sepaloid, the stamens absent, and where there is a double row
+of carpels, by supposing these peculiarities to be due to "a
+prolification combined with penetration and fusion of two or more
+flowers," but it is surely more reasonable to conceive a second row of
+carpels placed above the first by the prolongation of the central part
+of the axis. Supposing this view to be correct, the inner calyx-like
+whorl might be considered either as a repetition of the calycine whorl,
+or it might be inferred that the corolla was present in the guise of a
+second calyx.</p>
+
+<p>Moquin-Tandon suggests another explanation&mdash;namely, that though the
+stamens are absent in these curious flowers, at least in their ordinary
+shape, they are represented by the lower row of carpels, which become,
+in process of development, fused with the upper or true carpels. If this
+were so, surely some intermediate conditions between stamen and carpel
+would occasionally be present; but such does not appear to be the
+case.<a name="FNanchor_133_133" id="FNanchor_133_133"></a><a href="#Footnote_133_133" class="fnanchor">[133]</a></p>
+
+<p>In some of the instances of so-called proliferous pears the carpels
+would seem to be entirely absent, and the dilated portion of the axis to
+be alone repeated. Thus, the axis dilates to form the lower fruit
+without any true carpels being produced, but at its summit a whorl of
+leaves (sepals) is formed; above these another swelling of the axis
+takes place also without the formation of carpels, and this, it may be,
+is terminated in its turn by a branch producing leaves. In these cases
+there is no true prolification, but simply an extension of the axis.
+That the outer portion (so-called calyx-tube) of these fruits is really
+an axile product there can now be little doubt; and, as if to show their
+axile nature, they occasionally produce leaves from their sides, as<span class='pagenum'><a name="Page_136" id="Page_136">[Pg 136]</a></span>
+before mentioned. Moquin, in the tenth volume of the 'Bulletin of the
+Botanical Society of France,' p. 73, says that when the case is one of
+prolification the lower fruit is larger and is formed of a fleshy mass;
+moreover, the line of demarcation between the fruits is more distinct,
+and there are traces of the seed-bearing cavity in the interior, and of
+calycine lobes at the top. On the other hand, if the case be one of
+hypertrophy merely, the lowermost fruit is the smallest, and there is no
+trace of seed-bearing cavity nor of sepals. See also under Hypertrophy.</p>
+
+<p>Some other malformations usually referred to prolification of the fruit
+seem due to branching of the inflorescence, as in <i>Plantago</i>, wheat,
+maize; or to a simple extension of the axis beyond its ordinary limit,
+as in some cones of firs, &amp;c. It is obvious that the true fruits in
+these cases are in no wise affected.</p>
+
+<p>From these considerations it would appear better to abandon the use of
+the expression prolification of the fruit, as unnecessary where it is
+really applicable, and as delusive in the numerous other cases where it
+is employed.</p>

+
+<p><b>Axillary prolification</b> is the term applied to those cases wherein one or
+more adventitious buds spring from the axils of one or more of the parts
+of the flower. Engelmann makes use of the word ecblastesis to denote the
+same condition. Both terms are open to the objection that they do not
+clearly enable us to distinguish prolification occurring within the
+flower from a similar state originating outside the flower, within the
+bracts of the inflorescence. This latter condition, called by
+Moquin-Tandon lateral prolification (see Prolification of the
+Inflorescence), is as truly axillary as that to which the name is
+restricted. In consequence of certain peculiarities in the structure of
+some flowers, to be hereafter alluded to, it is not in all cases easy to
+decide whether the new growth springs from the<span class='pagenum'><a name="Page_139" id="Page_139">[Pg 139]</a></span> interior of the flower,
+or from the inflorescence beneath the flower.</p>
+
+<p>The accessory bud presents itself as a leaf-bud, a branch, a flower-bud,
+or a miniature inflorescence; it may be sessile, but is far more
+frequently stalked, and in more than half the number of cases it is a
+flower-bud or an inflorescence. There may be one or more of these buds;
+if two only, then they are usually placed directly opposite one to the
+other, on the opposite sides of the flower.</p>
+
+<p>It will be seen, from the appended list, that the orders and genera in
+which this description of adventitious growth occurs most frequently are
+the following:&mdash;<i>Crucifer&aelig;</i>, especially the genus <i>Brassica</i>;
+<i>Caryophyllace&aelig;</i>, e.g. <i>Dianthus</i>; <i>Resedace&aelig;</i>; <i>Leguminos&aelig;</i>, e.g.
+<i>Melilotus</i>, <i>Trifolium</i>, &amp;c.; <i>Rosace&aelig;</i>, e.g. <i>Rosa</i>, <i>Potentilla</i>,
+&amp;c.; <i>Umbellifer&aelig;</i>, and <i>Campanulace&aelig;</i>. For the most part, these are
+groups also peculiarly liable to central prolification.</p>
+
+<p>All the parts of the flower may be thus affected; but, as might have
+been anticipated from the foliaceous nature of the sepals, the new bud
+usually arises from within the axil of one of those organs. Next in
+frequency to the calyx, the pistil is subjected to this change&mdash;the
+carpels in such a case being disunited and leaf-like. The petals rank
+next, and lastly the stamens; these latter, indeed, are usually, but not
+invariably, absent, the new growth occupying their position. Hence it
+may well be that when such is the case, there is no real axillary
+prolification, but rather the substitution of a bud for a stamen.
+Generally, however, the position of the accessory bud is such that it
+may properly be referred to the axil of an undeveloped or rudimentary
+stamen.</p>
+
+<p>The largest number of instances of this malformation, not merely
+generically, but also individually, occurs in plants the members of
+whose floral whorls are not united one to the other; thus, it is far
+more common in polypetalous plants than in gamopetalous<span class='pagenum'><a name="Page_140" id="Page_140">[Pg 140]</a></span> ones. In the
+prolified flowers belonging to the latter group, the sepals, if not
+actually uncombined, are only united for a short distance. The same
+relationship, but in a much less degree, exists in the case of median
+prolification, as that aberration is likewise most commonly met with in
+polypetalous flowers. Another feature of interest is the rarity with
+which axillary prolification is found in irregular gamopetalous blooms.
+It may be that the irregular and comparatively excessive growth in some
+parts of these flowers, as compared with others, may operate in checking
+any luxuriant tendency in other directions.</p>
+
+<p>As in the case of median prolification, plants having an indefinite
+inflorescence are more liable to be affected with ecblastesis than those
+having a definite one. The degree of branching of the inflorescence may
+be noticed, as this deformity is far more common in plants whose
+peduncles are branched than in those which have either a solitary flower
+or an unbranched flower-stalk. More than two thirds of the entire number
+of genera cited as the subjects of this malformation have a branched
+inflorescence of some form or other; and about two thirds of the cases
+occur in genera having some form of indefinite inflorescence. If
+individual instances could be accurately computed, the proportion would
+be even higher.</p>
+
+<p>Fully three fourths of the entire number of genera recorded as
+occasionally the subjects of this irregularity possess in their usual
+state some peculiarity of the thalamus; for instance, in about a third
+of the whole number of genera the thalamus is more or less prolonged
+between some or other of the floral whorl, e.g. <i>Caryophyllace&aelig;</i>,
+<i>Potentilla</i>, <i>Anemone</i>, <i>Dictamnus</i>, <i>Umbellifer&aelig;</i>, &amp;c. About one
+fourth of the genera have numerous stamens or numerous carpels, or both,
+springing naturally from the thalamus. In others (about one sixth) the
+thalamus is enlarged into a disc, or else presents one or more<span class='pagenum'><a name="Page_141" id="Page_141">[Pg 141]</a></span>
+glandular swellings, <i>e.g.</i> <i>Reseda</i>, <i>Nymph&aelig;a</i>, <i>Crucifer&aelig;</i>. In the
+last-named family, as has been already remarked, prolification is very
+common. It would be interesting to ascertain precisely what part of an
+inflorescence is most liable to this affection; but as information on
+this point is but rarely given in the records of these cases, I can only
+give the results of my own observations, which go to show that, in a
+many-flowered inflorescence, those flowers at the outside, or at the
+lower portion, seem to be more frequently the subjects of this change
+than those situated elsewhere. This may probably be accounted for by the
+fact that the malformation is met with most generally in plants with an
+indefinite form of inflorescence, and therefore the lowermost or
+outermost flowers are most fully nourished; the upper flowers being in a
+less advanced condition, the change is more likely to be overlooked in
+them; or it may be that from the unusual luxuriance in the lower
+flowers, the upper ones may be either present in their ordinary
+condition, or may be (as indeed frequently happens) stunted in the size
+and proportion of their several parts.</p>
+
+
+
+<p><b>Axillary foliar prolification of the flower.</b>&mdash;The formation of an
+adventitious leaf-bud in the axil of any of the parts of the flower is
+not of such common occurrence as the development of a flower-bud in
+similar situations, nor is it so frequent as median foliar
+prolification. I have seen leafy shoots proceeding from the axils of the
+sepals in the flowers of <i>Brassica</i>, and a similar occurrence has been
+noticed in <i>Caltha palustris</i>, <i>Herreria parviflora</i>, and other plants.
+Dr. Marchand's flowers of <i>Anagallis</i>, previously referred to at p. 117,
+showed good illustrations of this occurrence, as also some specimens
+described by Kirschleger in <i>A. ph&oelig;nicea</i>.<a name="FNanchor_134_134" id="FNanchor_134_134"></a><a href="#Footnote_134_134" class="fnanchor">[134]</a> Steinheil has figured
+and described<a name="FNanchor_135_135" id="FNanchor_135_135"></a><a href="#Footnote_135_135" class="fnanchor">[135]</a> a flower of <i>Scabiosa</i><span class='pagenum'><a name="Page_142" id="Page_142">[Pg 142]</a></span> in which there was an
+adventitious formation of leafy shoots in the axil of the outer calyx.
+In some flowers, such as <i>Convolvulus</i>, <i>Anemone</i>, &amp;c., the exact nature
+of the sub-floral leaves is uncertain, <i>i.e.</i> it is open to doubt
+whether the organs in question are bracts or leaves pertaining to the
+inflorescence, or whether they are really parts of the flower. When
+leafy shoots are formed in the axils of such organs, the adventitious
+growth may be referred to extra-floral prolification, prolification of
+the inflorescence that is, or to axillary prolification, according to
+the view taken of the real nature of the sub-floral leaves. So far as
+the mere occurrence of prolification is concerned, it is not very
+material which view be adopted. The same remark applies to cases where
+leaf-buds occur on the outer surface of inferior ovaries, as in
+<i>Rosace&aelig;</i>, <i>Pomace&aelig;</i>, <i>Philadelphus</i>, or <i>Tetragonia expansa</i>, as
+elsewhere mentioned.</p>
+
+<p>It would seem more consistent with the general arrangements of parts,
+that the adventitious buds should be formed more frequently outside than
+within the flower proper.</p>
+
+<p>Knight<a name="FNanchor_136_136" id="FNanchor_136_136"></a><a href="#Footnote_136_136" class="fnanchor">[136]</a> figures and describes the occurrence of small tubers or
+fleshy leaf-buds in the axils of the sepals of a potato, a curious
+illustration of the real morphological nature of the tuber.</p>
+
+
+
+<p><b>Axillary floral prolification of the flower.</b>&mdash;As already stated, this is
+of more common occurrence than the formation of a leaf-bud in a similar
+situation. Any of the parts of the flower may thus subtend a flower-bud,
+though probably the new buds more frequently originate in the axils of
+the sepals than in the other whorls. In <i>Crucifer&aelig;</i> the change in
+question is, relatively speaking, very common. In cauliflowers and
+broccoli I have frequently met with stalked flowers proceeding from the
+axils of the sepals, so also in some fuchsias I have seen a ring of
+stalked flower-buds alternating<span class='pagenum'><a name="Page_143" id="Page_143">[Pg 143]</a></span> with the petals, which, together with
+the stamens and pistil, remained unaffected. The number of parts in the
+supernumerary structures is generally less than the normal flowers.</p>
+
+<p>In Mr. Herbert Spencer's 'Principles of Biology,' part iv, p. 37, are
+figured and described some monstrous inflorescences in <i>Angelica</i> and
+other <i>Umbellifer&aelig;</i>, from which, amongst other things, the author draws
+the conclusion that there is no absolute distinction between leaf and
+branch. Without staying for the moment to discuss this matter, it may
+here be said that the Umbellifers in question apparently owe their
+peculiarities rather to axillary prolification within the flower, or to
+prolification of the inflorescence, than to an actual transformation of
+a flower or any portion of a flower into an umbellule.<a name="FNanchor_137_137" id="FNanchor_137_137"></a><a href="#Footnote_137_137" class="fnanchor">[137]</a></p>
+
+<p>In the 'Gardeners' Chronicle,' 1855, p. 551, an instance is figured of
+the production of a supernumerary flower proceeding from the axil of a
+stamen in a species of <i>Nymph&aelig;a</i> (fig. 65). The ovary in this case was
+wanting, but in its place was a tuft of small leaves. It is curious that
+among Dr. Kirk's drawings of east tropical African plants now at Kew,
+there should be one representing a precisely similar state of things.
+The species in both instances was <i>Nymph&aelig;a Lotus</i>, or a cultivated
+variety of it.</p>
+
+<p>M. Wesmael<a name="FNanchor_138_138" id="FNanchor_138_138"></a><a href="#Footnote_138_138" class="fnanchor">[138]</a> describes a very singular case of what appears to have
+been referable to axillary prolification in the flowers of <i>Carex
+acuta</i>. The rachillus is described as prolonged through the utricle by
+the side of the stigmas, bearing on its side a bract, then a secondary
+utricle, from the axil of which sprung a short stem surmounted by an
+ovary. Wigand, 'Flora,' 1856, mentions a similar change in <i>Carex
+glauca</i>. In this instance the base of the female inflorescence bore
+lateral spikes, which projected from the utricles; some of these
+adventitious spikes were female, others<span class='pagenum'><a name="Page_144" id="Page_144">[Pg 144]</a></span> female below and male above,
+others, again, wholly male.</p>

+<p class="caption"> <span class="smcap">Fig.</span> 65.&mdash;Flower of <i>Nymph&aelig;a Lotus</i>, var., showing axillary floral prolification. The section also shows the tuft of leaves that occupied the place of the ovary.</p>
+</div>
+
+<p>Various changes in the form and arrangement of the several floral whorls
+accompany axillary prolification; some of these affect the particular
+organ or organs implicated, and these only, while in other cases some
+other parts of the flower likewise undergo modification. The changes
+most commonly met with are such as may be classed under Goethe's theory
+of retrograde metamorphosis; for instance, if a supplementary bud be
+developed in the axil of a sepal, that sepal is likely to be more than
+ordinarily leaf-like in appearance. The dislocation of the affected
+sepal from its fellows is a very frequent occurrence; in cases of this<span class='pagenum'><a name="Page_145" id="Page_145">[Pg 145]</a></span>
+kind the detached sepal is placed below the others, thus approximating,
+in position as well as in function, to the bracts. In some of the
+instances of proliferous pears, on which I shall have occasion to
+comment, the sepals are described as sharing in the succulent character
+of the fruit.</p>
+
+<p>The petals, under such circumstances, often exist in the guise of sepals
+or of small leaves; and instances are recorded wherein the place of the
+calyx and corolla was supplied by a succession of overlapping green
+scales, from the axils of which the new buds arose. M. Germain de Saint
+Pierre records such a case in <i>Trifolium repens</i>, wherein the calyx and
+corolla were replaced by overlapping scales, in the axils of each one of
+which arose a flower; above there was a row of stamens, and in the
+centre a pistil in the guise of a trifoliate leaf.<a name="FNanchor_139_139" id="FNanchor_139_139"></a><a href="#Footnote_139_139" class="fnanchor">[139]</a> Such instances
+seem to afford an extreme degree of a more common change, viz., the
+diminished size and contracted appearance of the sepals and petals when
+affected with axillary prolification. They have also a close
+relationship to such developments as we see in the wheat-ear carnation,
+in certain species of the genus <i>M&aelig;sa</i> and others, wherein the calyx is
+repeated over and again, to the partial or complete suppression of the
+other parts of the flower. All these cases may be in part explained by
+the operation of the principle of compensation.</p>
+
+<p>So far as the <ins title="andr&aelig;cium in original">andr&oelig;cium</ins> is concerned, the stamens either remain
+unaltered, or they are present in a more or less petal-like condition;
+but it far more frequently happens that the stamens are entirely
+suppressed, the adventitious bud supplying their place; thus was it in
+the <i>Dianthus</i> represented in the adjoining woodcut, fig. 66, where the
+stamens were entirely absent, and their places supplied by
+flower-bearing branches. This <i>Dianthus</i> has the more interest from its
+similarity to the one described by Goethe, Metam. der Pflanzen,<span class='pagenum'><a name="Page_146" id="Page_146">[Pg 146]</a></span> cap.
+16, sect. 105; but in that instance median prolification also existed.
+For my specimens I am indebted to Mr. T. Moore.</p>

+</div>
+
+<p>The pistil, too, is necessarily subject to very grave alterations when
+affected with this malformation. It is separated into its constituent
+carpels; and these assume a leaf-like aspect, and are in the great
+majority of instances destitute of ovules. Indeed, virescence or
+chloranthy is very intimately connected with this aberration, as might
+have been anticipated, for if the parts of the flower assume more or
+less of the condition of stem-leaves or bracts, it is quite natural to
+expect that they will partake likewise of the attributes of leaves, even
+at the expense of their own peculiar functions.</p>
+
+<p>It occasionally happens that an adventitious bud arises from the axil of
+a monocarpellary pistil. This takes place sometimes in <i>Leguminos&aelig;</i>, and
+seems to have been more frequently met with in <i>Trifolium repens</i> than
+in other plants. The species named is, as is well known, particularly
+subject to a reversion of the outer whorls of the flower to leaves, and
+even to a leaf-like condition of the pistil. There are on record
+instances wherein a leaf-bud has been placed in the axil of a<span class='pagenum'><a name="Page_147" id="Page_147">[Pg 147]</a></span> more or
+less leaf-like carpel; while at other times a second imperfect carpel
+has been met with in the axil of the first.<a name="FNanchor_140_140" id="FNanchor_140_140"></a><a href="#Footnote_140_140" class="fnanchor">[140]</a> I have myself seen
+numerous imperfectly developed cases of this kind.</p>
+
+<p>It may be asked whether such cases are not more properly referable to
+central prolification&mdash;whether the axis is not in such flowers
+terminated by two, rather than by one carpel? It is, however, generally
+admitted by morphologists that the solitary carpel of <i>Leguminos&aelig;</i> is
+not terminal, but is the sole existing member of a whorl of carpels, all
+the other members of which are suppressed as a general rule, though
+exceptional instances of the presence of two and even of five carpels
+have been described.<a name="FNanchor_141_141" id="FNanchor_141_141"></a><a href="#Footnote_141_141" class="fnanchor">[141]</a></p>
+
+<p>Again, the adventitious bud or carpel is placed, not laterally to the
+primary one, or opposite to it, on the same level, but slightly higher
+up&mdash;in fact, in the axil of the primary carpellary leaf. Griffith
+figures and describes<a name="FNanchor_142_142" id="FNanchor_142_142"></a><a href="#Footnote_142_142" class="fnanchor">[142]</a> an instance of the kind in a species of
+<i>Melilotus</i>. The stalk of the ovary is mentioned as having a sheathing
+base, bearing in its axil a prolongation of the axis of inflorescence,
+in the form of a short spike with hairy bracts and imperfect flowers,
+the latter having a well-formed calyx and rudimentary petals and
+stamens. Griffith infers, from this specimen, that the legume is not to
+be considered as a terminal leaf.</p><p><span class='pagenum'><a name="Page_148" id="Page_148">[Pg 148]</a></span></p>

+
+<p><b>Complicated prolification.</b>&mdash;From what has been before stated it may be
+seen that prolification of two or more kinds may coexist in the same
+flower. Mixed leafy and floral prolification is not unfrequent in
+proliferous roses, where a shoot is, as it were, prolonged through the
+centre of the original flower and terminated by a<span class='pagenum'><a name="Page_152" id="Page_152">[Pg 152]</a></span> second flower, or
+even by a cluster, as is well shown in the accompanying figure (fig.
+67). Median and axillary prolification, also, not unfrequently coexist
+in the same flower; thus, in a proliferous rose forwarded to me by Mr.
+W. Thomson (fig. 68), the following changes were observed:&mdash;the swollen
+portion below the calyx, the "hip," was entirely absent; the sepals were
+leaf-like in aspect, the petals unaffected; above the petals the axis
+was prolonged for a short distance and then bore a circlet of miniature,
+sessile roses, destitute, indeed, of calyx, but provided with numerous
+petals, stamens, and pistils. Above these lateral flowers, the prolonged
+axis bore a number of scales in many rows. The scales were in their turn
+surmounted<span class='pagenum'><a name="Page_153" id="Page_153">[Pg 153]</a></span> by a whorl of five perfect leaves, beyond which, again, the
+axis was prolonged into a leafy shoot terminated by a flower bud, the
+whole constituting a remarkably complicated admixture of elements
+belonging to the flower, the bud, the inflorescence, and the
+leafshoot.<a name="FNanchor_143_143" id="FNanchor_143_143"></a><a href="#Footnote_143_143" class="fnanchor">[143]</a></p>
+
+<p>Proliferous flowers of Orchids also occasionally present great
+complexity in the arrangement of their parts. An instance of this kind
+was described by myself from specimens furnished by Dr. Moore, of
+Glasnevin, in the 'Journal of the Linnean Society,' vol. ix, p. 349,
+tabs. x, xi, and from which the following summary is extracted:</p>
+

+</div>
+
+<p>The primary flowers were composed of five distinct whorls, and of at
+least two others less perfectly developed. These primary flowers did not
+give rise to<span class='pagenum'><a name="Page_154" id="Page_154">[Pg 154]</a></span> median formations, but they produced secondary buds in the
+axils of the segments of the perianth. These latter buds were themselves
+the subject of tertiary prolification of both kinds, median and
+axillary. The tertiary median growths, like the primary flower, did not
+develop median buds, but only lateral ones&mdash;quaternary axillary
+prolification.</p>
+
+<p>The accompanying diagrams are intended to show the plan of arrangement
+in these flowers. Fig. 69 shows the disposition of parts in the primary
+flower and the situation of the axillary buds. Fig. 70 shows the primary
+flower without any central prolongation, but giving off axillary buds,
+two of which are shown in the diagram, 2, 2; these are, each of them,
+the subject of both median, 3, 3, and axillary prolification, 4', 4'.</p>

+<p><b>Prolification of the embryo.</b>&mdash;This term was applied by Moquin-Tandon to
+a peculiar condition of the almond (<i>Amygdalus</i>), in which, indeed, it
+is not of unfrequent occurrence. In these cases one almond encloses
+within its cotyledons a second embryo, and this, again, in some
+instances, a third, the little plants being thus packed like so many
+boxes one within the other. The supplementary embryos are, in the ripe
+state at least, quite separate and detached one from another. These
+cases differ from the ordinary instances wherein there is an increased
+number of embryos in one seed in their<span class='pagenum'><a name="Page_156" id="Page_156">[Pg 156]</a></span> position. In the latter case, as
+often happens in the seeds of the orange, the new products are placed by

+the carpels six ribs, three to each. This diversity in number is thus
+explained:&mdash;A circle of vascular tissue ran round the interior of the
+calyx-tube, at its junction with the limb, and at the point of insertion
+of the petals and stamens. The vascular circle seemed to be formed from
+the confluence of the ten ribs from below. Of the five ribs in each half
+of the calyx, the three central ones were joined together just at the
+point of confluence with the vascular circle, above which they formed
+but a single rib&mdash;that traversing the centre of the carpellary leaf; the
+two lateral ribs of each half of the calyx seemed to be continuous,
+above the vascular rim, with the lateral ribs of the carpel; these
+lateral ribs were connected on either side with the central one by short
+branches of communication. The disposition of the ten ribs may be thus
+represented:&mdash;
+</p>
+
+<pre>
+    1   1   1              1   1   1
+    3 2 3 2 3              3 2 3 2 3
+    1 1 1 1 1              1 1 1 1 1
+</pre>
+
+<p>
+The lower line of figures represents the calycine ribs, the middle row
+shows how each of these ribs is divided at the vascular rim, and the
+uppermost row shows their distribution above the rim. From this it will
+be seen that six of the calycine ribs divide into three branches, one
+prolonged upwards as a lateral or median rib into the carpellary leaf,
+the other running horizontally to join with similar branches sent out
+from the neighbouring rib; the four intermediate calycine ribs divide
+into two branches only, which join the side branches of the first
+mentioned, but have no direct upward prolongation into the carpel. The
+ten ridges are placed opposite to the sepals and petals.</p></div>

+
+HETEROTAXY.</h4>
+
+
+<p>Under this category are here included a variety of deviations from the
+ordinary arrangement and position of parts which cannot conveniently be
+classed under the preceding or under other headings. The term heterotaxy
+is intended to apply to the production of organs in situations where,
+under usual circumstances, they would not be formed. It thus does not
+include cases of substitution, where one part is replaced by another, or
+more or less metamorphosed, nor cases of multiplication, nor of
+prolification which are characterised not only by the production of
+members in unwonted situations, but also in unwonted numbers. From the
+very nature of the anomalies, and specially from the scanty knowledge we
+possess concerning their mode of development, it is not possible to
+allocate them in all cases correctly, and moreover many of them might as
+well be placed in one group as in another.</p>
+
+
+
+<p><b>Formation of adventitious roots.</b>&mdash;This is of exceedingly common
+occurrence in a vast number of plants, so much so that in most cases it
+cannot be considered as in any way abnormal; there are, however, a few
+instances where the formation of these organs may be<span class='pagenum'><a name="Page_157" id="Page_157">[Pg 157]</a></span> considered to come
+within the scope of teratology, or, at least, where their production is
+the result of injury or of some unfavorable condition to which the plant
+is exposed.</p>
+
+<p>Thus the production of adventitious roots on the stem of the vine is
+considered to be due to untoward circumstances impairing the proper
+action of the ordinary subterranean roots. So, too, the formation of
+roots on the upper portions of stems that are more or less decayed
+below, as in old willows, is to be considered as an attempt to obtain
+fresh supplies through a more vigorous and healthy channel.</p>
+
+<p>A similar occurrence often arises as a consequence of some injury.
+Virgil had this circumstance in view when he wrote</p>
+
+<div class="poem"><div class="stanza">
+<span class="i6">"<i>Quin et, caudicibus sectis, mirabile dictu,</i><br /></span>
+<span class="i0"><i>Truditur e sicco radix oleagina ligno.</i>"&mdash;'Georg.' Bk. ii.<br /></span>
+</div></div>
+
+<p>I have seen many specimens of adventitious roots produced on the olive
+in the way just mentioned.</p>
+
+<p>In the 'Gardeners' Chronicle,' January 8th, 1853, p. 21, is described a
+curious formation of roots in the fissure between two divisions of a
+laburnum stem. In the same journal, January 1st, 1853, p. 4, Mr. Booth
+mentions the case of a Cornish elm, the trunk of which was divided at
+the top into two main divisions, and from the force of the wind or from
+some other cause the stem was split down for several feet below the
+fork. Around the edges of the fracture, layers of new bark were formed,
+from which numerous roots issued, some measuring an inch in diameter and
+descending into the cleft portion of the tree: similar instances must be
+familiar to all observers.</p>
+
+<p>It may happen that these roots sent down into the cavity of a decaying
+trunk may, after a time, become completely concealed within it, by the
+gradual formation and extension of new wood over the orifice of the
+cavity formed by the death and decay of the old wood. Such is presumed
+to be the explanation of a specimen of<span class='pagenum'><a name="Page_158" id="Page_158">[Pg 158]</a></span> this kind in the possession of
+the writer, and taken from a cavity in an apparently solid block of
+rosewood; externally there were no marks to indicate the existence of a
+central space, but when the block was sawn up for the use of the
+cabinet-maker, this root-like structure was found in the centre and
+attached to one end of the cavity.</p>
+
+<p>The production of roots which ultimately serve as props to support the
+branches, or as buttresses to compensate for the increasing weight of
+branches and foliage, is also a familiar occurrence. The huge gnaurs and
+burrs met with occasionally on some trees often produce great
+quantities, not only of adventitious buds, but of roots also.</p>

+</div>
+
+<p>The leaves, equally with the stems, have the power of emitting roots
+under certain conditions, as when the leaves are in close contact with
+moist soil or as the result of injury. This happens in some plants more
+readily than in others&mdash;<i>Bryophyllum calycinum</i> is a well-known
+instance. Mr. Berkeley has described the formation of roots from the
+fractured leaves of celery,<a name="FNanchor_147_147" id="FNanchor_147_147"></a><a href="#Footnote_147_147" class="fnanchor">[147]</a><span class='pagenum'><a name="Page_159" id="Page_159">[Pg 159]</a></span> and also in a cabbage where a snail
+"having gnawed a hole into the middle of a leaf at its junction with the
+stem, a fascicle of roots was formed, bursting through the tissue lining
+the cavity, and covered with abundant delicate hairs after the fashion
+of ordinary radicles."</p>

+<p class="caption"> <span class="smcap">Fig.</span> 72.&mdash;Germinating plant of mango, showing production of roots from one of the cotyledons (from the Kew Museum).</p>
+</div>
+
+<p>The production of adventitious roots is not limited to the ordinary
+leaves of the plant, but may be manifested on the cotyledons; thus
+Irmisch describes cases of this kind in the cotyledons of <i>Bunium
+creticum</i> and <i>Carum Bulbocastanum</i>.<a name="FNanchor_148_148" id="FNanchor_148_148"></a><a href="#Footnote_148_148" class="fnanchor">[148]</a> I have figured and described

+
+<p>To this formation of adventitious roots the gardener owes the power he
+has of propagating plants by cuttings, <i>i.e.</i>, small portions of the
+stem with a bud or buds attached, or in some cases from portions of the<span class='pagenum'><a name="Page_160" id="Page_160">[Pg 160]</a></span>
+leaves, of the roots themselves, or even of the fruit, as in the case of
+the cactus (Baillon). Care also has to be exercised in grafting certain
+fruit trees not to allow the grafted portion to be too close to the
+ground, else the scion throws out roots into the soil, and the object of
+the cultivator is defeated.</p>

+</div>
+
+<p>Layering is another garden operation dependent on the formation of these
+organs, and advantage is also sometimes taken of this tendency of some
+plants to produce roots when injured to reduce the dimensions of a plant
+when getting too large for the house in which it is growing. By
+gradually inducing the production of new roots from the central or upper
+portions of the stem, it becomes possible, after a time, to sever the
+connection between the original roots and the upper portion of the
+trunk, and thus secure a shortened plant.</p>
+
+<div class="blockquot"><p>On the subject of adventitious roots, &amp;c., reference may be
+made to Tr&eacute;cul, 'Ann. Sc. Nat.,' 1846, t. v, p. 340, et vi, p.
+303. Duchartre, 'Elements de Botanique,' p. 219. Lindley,
+'Theory and Practice of Horticulture.' Thomson's 'Gardener's
+Assistant,' pp. 374, <i>et seq.</i>; and any of the ordinary
+botanical text-books.</p></div>
+
+
+
+<p><b>Formation of adventitious buds on roots.</b>&mdash;One of the characteristics by
+which roots are distinguished from stems in a general way consists in
+the absence of buds; but, as is well known, they may be formed on the
+roots under certain circumstances, and in certain plants, e.g.,<span class='pagenum'><a name="Page_161" id="Page_161">[Pg 161]</a></span> <i>Pyrus
+Japonica</i>, <i>Anemone Japonica</i>, &amp;c. What are termed suckers, owe their
+origin to buds formed in this situation.</p>
+
+<p>If roots be exposed or injured, they will frequently emit buds. The
+well-known experiment of Duhamel, in which a willow was placed with the
+branches in the soil and the roots in the air, and emitted new buds from
+the latter and new roots from the former, depended on this production of
+adventitious organs of either kind.</p>
+
+<p>Gardeners often avail themselves of the power that the roots have of
+producing buds to propagate plants by cuttings of the roots, but in many
+of these cases the organ "parted" or cut is really an underground stem
+and not a true root.</p>
+
+<p>M. Claas Mulder has figured and described a case in the turnip-radish of
+the unusual formation of a leafy shoot from the root, apparently after
+injury.<a name="FNanchor_150_150" id="FNanchor_150_150"></a><a href="#Footnote_150_150" class="fnanchor">[150]</a> From the figure it appears as if the lower portion of the
+root had been split almost to the extremity, while the upper portion
+seems to have a central cavity passing through it. From the angle,
+formed by the split segments below, proceeds a tuft of leaves, some of
+which appear to have traversed the central cavity and to have emerged
+from the summit, mingling with the other leaves in that situation. The
+production of a flower-bud has even been noticed on the root of a
+species of <i>Impatiens</i>.</p>
+
+
+
+<p><b>Formation of shoots beneath the cotyledons.</b>&mdash;The tigellar or axial
+portion of the embryo plant, as contrasted with the radicle proper, is
+very variously developed in different cases; sometimes it is a mere
+"collar" bearing the cotyledons, while at other times it is of
+considerable size. Generally it does not give origin to shoots or leaves
+other than the seed-leaves, but occasionally shoots may be seen
+projecting from it below the level of the cotyledons. This happens
+frequently in seedling plants of <i>Anagallis arvensis</i>, <i>Euphorbia</i><span class='pagenum'><a name="Page_162" id="Page_162">[Pg 162]</a></span>
+<i>peplus</i>, and other species, <i>Linaria vulgaris</i>, some <i>Umbellifer&aelig;</i>,
+&amp;c.<a name="FNanchor_151_151" id="FNanchor_151_151"></a><a href="#Footnote_151_151" class="fnanchor">[151]</a></p>
+
+
+
+<p><b>Adventitious formation of leaves.</b>&mdash;The term phyllomania has been vaguely
+applied both to the production of an unwonted number of leaves and to
+their development in unusual situations. Under the present heading the
+latter class of cases are alone included. The extraordinary tendency in
+some Begonias to develop leaves or leafy excrescences from their
+surfaces is elsewhere alluded to, and is, in reality, a species of
+hypertrophy or over-luxuriant growth.</p>
+
+<p>In some flowers where the inferior ovary is supposed to be, in part at
+least, formed by a dilatation of the top of the flower-stalk, leaves
+have been met with proceeding from the surface of the ovary or fruit, as
+in <i>Crat&aelig;gus tanacetifolia</i>, roses, pears, gooseberries, &amp;c. In a
+specimen of <i>Nymph&aelig;a alba</i> I have met with scale-like leaves projecting
+from the surface of the fruit (or torus?), and which did not appear to
+be metamorphosed stamens or styles (fig. 76).</p>

+</div>
+
+<p><b>Production of leaves on a usually leafless inflorescence.</b>&mdash;The
+development of the bracts of an inflorescence to such an extent that
+they resemble ordinary leaves is elsewhere alluded to as of common
+occurrence. It happens far less frequently that leaves are developed on
+an inflorescence usually destitute of them, without any metamorphosis or
+substitution, and without any formation<span class='pagenum'><a name="Page_164" id="Page_164">[Pg 164]</a></span> of adventitious buds, such as
+happens in prolification. Such a partial change from a floriferous to a
+foliiferous branch may be seen in a specimen of <i>Sambucus nigra</i> in the
+Smithian herbarium in the Linnean Society, where the ultimate branches
+of the cyme bear small leaves. My attention was directed to this
+specimen by the Rev. W. Newbould.</p>
+
+<p>Jacquin figures an analogous case in <i>Sempervivum sediforme</i>,<a name="FNanchor_152_152" id="FNanchor_152_152"></a><a href="#Footnote_152_152" class="fnanchor">[152]</a> in
+which the branches of the inflorescence were prolonged into leafy
+shoots.</p>
+
+<p>Sometimes from the side of a flower-stalk or scape, which usually does
+not bear leaves, those organs are produced. The common dandelion,
+<i>Taraxacum</i>, sometimes offers an illustration of this, and also the
+daisy (<i>Bellis</i>).<a name="FNanchor_153_153" id="FNanchor_153_153"></a><a href="#Footnote_153_153" class="fnanchor">[153]</a> In a specimen of fasciated cowslip given me by
+Mr. Edgeworth there was a similar formation of leaves on the flattened
+stalk.</p>
+
+
+
+<p><b>Production of leaves or scales in place of flower-buds.</b>&mdash;The position of
+the leaf and of the flower-buds respectively is, in most plants, well
+defined, but occasionally it happens that the former is formed where,
+under ordinary circumstances, the latter organ should be. This may
+happen without the formation of any transitional organs between the two,
+and without actual increase in the number of the buds. Where there is
+evidently a passage from leaf-bud to flower-bud, or <i>vice vers&acirc;</i>, the
+case would be one of metamorphy. If the number of buds be augmented, or
+they be mixed with the flower-buds, then it would be referable to leafy
+prolification of the inflorescence. There remains a class of cases
+wherein there is a complete substitution of one structure for the other,
+it may be without the slightest indication of transition between the
+two, and without any admixture of leaf-buds among flower-buds,<span class='pagenum'><a name="Page_165" id="Page_165">[Pg 165]</a></span> or any
+absolute increase in the number of organs, as in Prolification. Such a
+case is represented in fig. 78, which shows a portion of the stem of a
+species of <i>Valeriana</i>, bearing at the summit, not an inflorescence, but

+<p>Drs. Hooker and Thomson relate that in Northern India the flowers of
+<i>Anemone rivularis</i> are very generally absent, and their place supplied

+
+<p>A similar appearance has been noticed in <i>Composit&aelig;</i>, and I owe to the
+kindness of Professor Oliver the communication of a specimen of a
+species of <i>Bidens</i> from<span class='pagenum'><a name="Page_166" id="Page_166">[Pg 166]</a></span> Peru, in which the capitula, instead of
+consisting of florets, as usual, contained tufts of linear ciliolated
+bracts within the involucre, without a trace of flowers. In the eleventh
+volume of the 'Linn&aelig;a,' 1837, p. 301, Von Cesati figures and describes
+an analogous case in <i>Carduus crispus</i>. The same author[1] records a
+similar instance in the umbel of <i>Seseli coloratum</i>, where the place of
+the flowers was occupied by stalked tufts of leaves. In the 'Gardeners'
+Chronicle,' October 6th, 1860, p. 894, is mentioned an instance where
+the blossoms of the pea were entirely absent, and their place supplied
+by accumulations of small, ovate, green scales, thus presenting an
+appearance similar to that brought about by the inordinate
+multiplication of the sepals in the "wheat-ear carnation," and in the
+Sweet William, and not unlike the condition met with in <i>Bryophyllum
+proliferum</i>. In <i>Digitalis purpurea</i> a similar anomaly is sometimes met
+with.</p>
+
+<p>In the apple I have observed leafy shoots bearing terminal tufts of
+leaves where the flower should have been, so that what, under ordinary
+circumstances would be a corymb of flowers, is here represented by a
+series of tufts of leaves. In the cultivated azaleas also, leafy shoots
+occupying the position of the flower may occasionally be met with.</p>
+
+<p>In <i>Bouchea hyderabadensis</i> I have seen the inflorescence more than
+usually branched and covered with little tufts of bracts, without a
+trace of true flower. A similar condition seems not infrequent in
+<i>Gentiana Amarella</i>, as I have not only met with the plant myself in
+this condition, but have been favoured with specimens by Mr. Pamplin,
+Mr. Darwin, and others. In <i>Phyteuma spicatum</i> an analogous appearance
+has been recorded.</p>
+
+<p>Among Griffith's collections from Affghanistan is a species of willow
+(<i>Salix</i>) in which the inflorescence replaced by a much branched
+panicle, bearing a quantity of minute bracts, in the axils of which
+nestle numerous small buds. In another specimen the inflorescence<span class='pagenum'><a name="Page_167" id="Page_167">[Pg 167]</a></span>
+preserves its usual catkin-like shape, but the flowers are replaced by
+little tufts of leaves. M. Germain de Saint Pierre mentions a case
+wherein the flowers of <i>Alisma parnassifolia</i> were completely replaced
+by leaf-buds.<a name="FNanchor_155_155" id="FNanchor_155_155"></a><a href="#Footnote_155_155" class="fnanchor">[155]</a></p>

+which the inflorescence<span class='pagenum'><a name="Page_168" id="Page_168">[Pg 168]</a></span> is made up of collections of scales or bracts

+
+<p>"Rose willows" (fig. 80) owe their peculiar appearance to a similar
+cause, the scales of the catkin being here replaced by closely crowded
+leaves. These aggregations of scales or leaves are not confined to the
+inflorescence, but may be found in other parts of the plant, and may be
+frequently met with in the willow, birch, oak, &amp;c., generally as the
+result of insect puncture. On the other hand, the production of leaves
+or leaf-buds in place of flowers is, as is well known, generally the
+consequence of an excess of nutrition, and of the continuance rather
+than of the arrest of vegetative development.<a name="FNanchor_157_157" id="FNanchor_157_157"></a><a href="#Footnote_157_157" class="fnanchor">[157]</a> It has even been

+
+<p><b>Viviparous plants.</b>&mdash;The spikelets of certain grasses are frequently
+found with some of their constituent parts completely replaced by
+leaves, like those of the stem, while the true flowers are usually
+entirely absent. A shoot, in fact, is formed in place of a series of
+flowers. In these cases it generally happens that the outermost glumes
+are changed, sometimes, however, even the outer and inner pale&aelig; are
+wholly unchanged, while there is no trace of squamul&aelig; or of stamens and
+pistils within them, but in their place is a small shoot with miniature
+leaves arranged in the ordinary manner.</p><p><span class='pagenum'><a name="Page_169" id="Page_169">[Pg 169]</a></span></p>

+<p>From an examination of the structure of viviparous grasses Von Mohl was
+led to the conclusion that the lower palea is to be considered as a

+
+<p>In the genus <i>Allium</i> an analogous formation of little buds or bulbils
+takes place in lieu of flowers; this is specially the case with <i>A.
+vineale</i>, the flowers of which are rarely seen.</p>
+
+<p>Other illustrations of a similar character, where the adventitious

+
+
+
+<p><b>Formation of buds on leaves.</b>&mdash;The formation of little bulbs upon the
+surfaces or edges of leaves, forming what are called viviparous leaves,
+has long been familiar to botanists amongst Alliums. Professor Alexander
+Braun,<a name="FNanchor_160_160" id="FNanchor_160_160"></a><a href="#Footnote_160_160" class="fnanchor">[160]</a> who has paid much attention to this subject, divides cases
+of this kind according to the position of the buds; thus, for instance,
+they are sometimes formed upon the upper portion of the leaf or petiole,
+as in many ferns, in <i>Nymph&aelig;a guineensis</i>, some <i>Arads</i>, &amp;c. The same
+condition has been met with as a teratological occurrence in the leaves
+of <i>Cardamine pratensis</i>, <i>Hyacinthus Pouzolzii</i>, <i>Drosera
+intermedia</i>,<a name="FNanchor_161_161" id="FNanchor_161_161"></a><a href="#Footnote_161_161" class="fnanchor">[161]</a> <i>Arabis pumila</i>, <i>Chelidonium majus</i>, <i>Chirita

+of <i>Begonia</i> possess the power of emitting buds from the petioles and
+veins of the leaf; the little ramenta or scales which so plentifully
+beset the surface of some of these plants likewise, in some instances,
+pass gradually into leaves. <i>B. phyllomaniaca</i>, Mart., is the species
+best known as manifesting this tendency, but others have it also.<a name="FNanchor_165_165" id="FNanchor_165_165"></a><a href="#Footnote_165_165" class="fnanchor">[165]</a></p>
+
+<p>Buds are also very often formed upon the margins of the leaf, the best
+known instance of which occurs in<span class='pagenum'><a name="Page_171" id="Page_171">[Pg 171]</a></span> <i>Bryophyllum calycinum</i>;
+Weinmann<a name="FNanchor_166_166" id="FNanchor_166_166"></a><a href="#Footnote_166_166" class="fnanchor">[166]</a> figures an instance of this kind in <i>Alchemilla minima</i>,
+or they may occur upon the lower surface of the leaf, as in
+<i>Ornithogalum scilloides</i> and <i>longe-bracteatum</i>. M. Duchartre<a name="FNanchor_167_167" id="FNanchor_167_167"></a><a href="#Footnote_167_167" class="fnanchor">[167]</a>
+mentions a case in the tomato in which the leaves gave origin to small
+leaf-bearing branches, which, of course, must have originated from buds,
+just in the same way as in the <i>Drosera</i> before mentioned.</p>

+modes as adopted by these skilful horticulturists&mdash;the one to make two
+or three deep cuts at the base of the bulb, destroying the nascent
+flower-stalk when, after a time, small bulbs are formed along the edges
+of the cut surfaces (figs. 84, 85). The other method is effected by
+scooping out the interior of the base of the bulb, thus leaving exposed
+the cut ends of the sheathing leaves arranged concentrically; along
+these lines the new bulbs are, after some time, formed in great numbers
+(fig. 86).</p>

+<p>This curious plant has been described and figured<span class='pagenum'><a name="Page_175" id="Page_175">[Pg 175]</a></span> by Irmisch in the
+13th volume of the 'Linn&aelig;a,' p. 124, t. iv; also by Professor Henslow,
+'Hooker's Journal of Botany,' 1849, vol. i, p. 33, tabs. 2, 3. The lower
+palea of this plant forms an inverted flower-bud upon its midrib. In
+some fresh specimens which I have lately examined I find the structure
+to be as follows:&mdash;On each notch of the rachis there are three spikelets
+(fig. 88), each one-flowered, and each provided with two linear glumes;
+the outer palea in all cases is three-lobed at the summit, the central
+lobe being oblong and hollow, forming a kind of hood (figs. 87&ndash;89), and
+covered with hairs, which are directed downwards towards the centre of
+the plant. The two lateral lobes are more<span class='pagenum'><a name="Page_176" id="Page_176">[Pg 176]</a></span> pointed than the central one;
+like it they are provided with hairs, but the hairs, in this case, are
+turned away from the centre of the plant. The cavity of the side lobes
+is generally empty, but that of the central lobe is occupied by a very
+slender stalk, which is apparently the termination of the midrib, but
+which is bent inwards at an acute angle, so as to occupy the hollow
+space (figs. 90&ndash;91). On this slender axis are developed two florets,
+more or less imperfect in their structure. Only one of the florets that
+I have seen contained a perfect ovary. The tips of the lateral lobes of
+the pale&aelig; in the primary flower are sometimes extended into a long awn.
+A similar awn may also be occasionally found on the tips of the pale&aelig; of
+the rudimentary florets. The occurrence of an adventitious axial
+structure with rudimentary flowers has been adduced in support of the
+opinion that the lower pale&aelig; is, at least so far as its midrib is
+concerned, an axial rather than a foliar structure, but in the present
+uncertain state of our knowledge as to the morphology of grasses it is
+hazardous to risk any explanation founded on so exceptional a case as
+that of the Nepaul barley.<a name="FNanchor_172_172" id="FNanchor_172_172"></a><a href="#Footnote_172_172" class="fnanchor">[172]</a></p>
+
+
+
+<p><b>Production of flower-buds in place of leaf-buds.</b>&mdash;Under natural
+circumstances this does not appear to be of so common occurrence as the
+change above alluded to, but by the art of the gardener the change is
+often effected. In rhododendrons and in peach trees and roses I have met
+with this change occurring without human agency. The means adopted by
+the gardener are such as check the luxuriance of the leaf-shoots,<a name="FNanchor_173_173" id="FNanchor_173_173"></a><a href="#Footnote_173_173" class="fnanchor">[173]</a>
+and this is effected in various ways, as by continuous "pinching" or
+removal of the leaf-buds, by pruning, ringing the bark, confining the
+roots, limiting the<span class='pagenum'><a name="Page_177" id="Page_177">[Pg 177]</a></span> supply of nutriment, and other means all based on
+the same principle. Some of the Cape bulbs (<i>Cyrtanthus</i>) are known not
+to produce their flowers till their leaves have received, in some
+manner, a check. Fires which often destroy the herbage thus have the
+effect of throwing the plant into bloom. A very remarkable instance is
+recorded of the production of flower-buds after an injury to the
+leaf-buds in the 'Bulletin of the Botanical Society of France,' vol. ix,
+p. 146. It appears that during the war of the French against the Arabs
+in Algiers, the latter planted several hundreds of Agaves with a view to
+obstruct the passage of the French cavalry. The soldiers hacked these
+plants with their sabres, and cut out the central tuft of leaves, or the
+heart, as gardeners call it. The following season almost every one of
+these Agaves sent up their large handsome flower-spikes. It is well
+known that, under ordinary circumstances, these plants do not flower
+except at long intervals of time.</p>
+
+
+
+<p><b>Presence of flowers on spines.</b>&mdash;That the spine, as a contracted branch,
+should occasionally produce flowers is not to be wondered at, though the
+occurrence is by no means common. M. Baillon showed at a meeting of the
+Botanical Society of France ('Bulletin,' vol. v, 1858, p. 316) a
+branched spine of <i>Gleditschia</i> bearing a flower at the end of each of
+the sub divisions. This was, therefore, strictly analogous with those
+cases in which the peduncle is normally spiney.</p>
+
+
+
+<p><b>Formation of flower-bud on the petals.</b>&mdash;An instance of this, it is
+believed, the only one on record, is cited in the 'Gardeners' Chronicle'
+for 1865, p. 760, by the Rev. M. J. Berkeley, who describes the
+formation of a flower-bud on the surface of a petal of <i>Clarkia
+elegans</i>. Reasoning from analogy there seems no reason why buds should
+not be formed on the petals as well as on the leaves.</p><p><span class='pagenum'><a name="Page_178" id="Page_178">[Pg 178]</a></span></p>
+
+
+
+<p><b>Formation of buds on fruits.</b>&mdash;This is a point of some moment with
+reference to the share which the axis takes in the production of
+"inferior" fruits. A very frequent malformation in pears is one wherein
+a second pear proceeds from the centre of the first, and even a third
+from the centre of the second.<a name="FNanchor_174_174" id="FNanchor_174_174"></a><a href="#Footnote_174_174" class="fnanchor">[174]</a> Pears are occasionally also observed
+arising either from the axils of the sepals of the primary pear or from
+the axil of leaves originating on the outer surface of the fruits&mdash;using
+the term fruit in its popular sense. These cases afford strong
+confirmation of the view that the outer portion of the so-called fruit
+in these plants is rather to be considered as an expansion and

+</div>
+
+<p>The fruits of <i>Opuntia Salmiana</i>, <i>O. fragilis</i>,<a name="FNanchor_178_178" id="FNanchor_178_178"></a><a href="#Footnote_178_178" class="fnanchor">[178]</a> <i>O. monacantha</i>,
+and of some species of <i>Echinocactus</i>, have been observed to form small
+fruit-like branches around their summits. M. Napol&eacute;on Doumet describes
+the fruit as ripening as usual, but as being destitute of seeds in the
+interior; after a little while the fruit begins to wither,<span class='pagenum'><a name="Page_179" id="Page_179">[Pg 179]</a></span> and then a
+circle of small buds, like those of the stem, may be seen at the top of
+the fruit, each bud springing from the axil of a little tuft of wool and
+spines found on the fruit. These little buds elongate into long shoots,
+produce flowers the following year, which flowers exhibit the same
+peculiarity. Gasparini and Tenore are said to have recorded the same
+fact as long since as 1832. The specimen from which the figure (fig. 93)
+was taken produced its fruits in the Royal Gardens at Kew, and is now
+preserved in the museum of that establishment. The adventitious growth
+in these cases appears to arise from the tufts of spines, which, it has
+been suggested, are the homologues of the sepals. There can, however, be
+little doubt that the outer and lower portion of the fruit of <i>Opuntia</i>
+and its allies is a dilatation of the flower-stalk. This is borne out by
+the fruits of <i>Pereskia</i>, which bear leaves on their surface arranged
+spirally; indeed, the fruits of <i>Pereskia Bleo</i> are mentioned as
+producing buds from their<span class='pagenum'><a name="Page_180" id="Page_180">[Pg 180]</a></span> summits, in the same way as the <i>Opuntia</i>
+just cited. <i>P. Bleo</i> is said, by M. Delavaud,<a name="FNanchor_179_179" id="FNanchor_179_179"></a><a href="#Footnote_179_179" class="fnanchor">[179]</a> to present this
+anomaly as a constant occurrence. On the summit of the primary fruit,
+arising apparently from the axils of the sepals, or of small leafy
+bracts in that situation, are a series of fruit-like branches, which, in
+their turn, are surmounted by others, even to the fourth generation.</p>
+
+<p>The fruits of <i>Tetragonia expansa</i> frequently have attached to their
+side a secondary flower or fruit in such a position as to lead to the
+inference that it springs from the upper portion of the peduncle which
+is dilated to invest the true carpels. In other instances it is due to
+an adhesion of the pedicel to the side of the fruit. In either case the
+production of an adventitious bud might be considered as an illustration
+of prolification of the inflorescence, though not as was supposed by
+Moquin and others of axillary prolification.<a name="FNanchor_180_180" id="FNanchor_180_180"></a><a href="#Footnote_180_180" class="fnanchor">[180]</a></p>
+
+<p>Buds have also been produced artificially on the surface of some of the
+fruits in the construction of which the axis is supposed to share; thus,
+the unripe fruits of some species of <i>Lecythis</i> were stated by Von
+Martius, at a meeting of the German Naturalists at Carlsruhe, to produce
+buds when placed in the earth. The fruit of these plants is probably of
+the same nature as that of the <i>Pomace&aelig;</i>, and Baillon<a name="FNanchor_181_181" id="FNanchor_181_181"></a><a href="#Footnote_181_181" class="fnanchor">[181]</a> succeeded in
+producing buds on the surface of the inferior ovary of <i>Jussi&aelig;a</i>.</p>
+
+<p>Some of the cases just mentioned have been considered to be instances of
+prolification of the fruit, but the fruit has little to do with the
+appearances in question.</p>
+
+
+
+<p><b>Formation of adventitious flowers and fruits within the ovary.</b>&mdash;This
+generally arises either from substitution of a<span class='pagenum'><a name="Page_181" id="Page_181">[Pg 181]</a></span> flower-bud for an ovule
+or from prolification; there are certain cases, however, where the new
+growth seems not to be either due to metamorphosis or to prolification
+strictly.</p>
+
+<p>The cut, fig. 94, represents a case where, in the dilated upper portion
+of the ovary of <i>Sinapis arvensis</i>, two flower-buds were found
+projecting from a raised central line, corresponding, as it would seem,
+to the midrib, and not to the margins of the carpel. Similar cases have
+occurred in <i>Nasturtium amphibium</i>, <i>Brassica Rapa</i>, and <i>Passiflora

+
+<p>In the normal flower there is a turbinate hollow calyx, whose limb is
+divided into five serrated lobes; alternating with these latter, and
+springing from the throat of the calyx, are the petals. Originating from
+the same annular disk as the petals are the stamens, seven or eight in
+number. The ovary is partially adherent, is surmounted by a style, and
+has two or three loculi with an axile placenta, to which several small
+curved ovules are attached. The malformed flowers did not present
+anything peculiar in their outer parts, nor did the ovary, partially
+immersed within the expanded top of the flower-stalk and the calyx-tube,
+which is continuous with that organ, show externally any indication of
+the change within. On cutting it across, however, in any direction,
+numerous perfect stamens (filaments and anthers) were seen projecting
+from the walls of the cavity (fig. 98). In most of the flowers the ovary
+was one-celled; but in a few there was the usual axile placenta; yet
+even in these latter cases the stamens originated from the walls of the
+cavity, and not from the placenta. The stamens presented different
+degrees of development; in some cases they were fully formed, the
+anther-lobes open, and the pollen exposed; while in other instances the<span class='pagenum'><a name="Page_184" id="Page_184">[Pg 184]</a></span>
+filaments were involute or circinate, just as the ordinary stamens are
+in the unexpanded flower-bud. In some cases imperfect stamens were
+found, mere barren filaments, with or without rudimentary anthers at the
+top. In no instance was there a perfect ovule, or, indeed, any trace of
+ovules. The stamens appeared to be arranged irregularly on the walls of
+the ovarian cavity; and while they were certainly more numerous at the
+lower portion (that now generally considered to be formed by the
+cup-like end of the pedicel), they were not wanting in the upper half of
+the ovary (or that which is probably formed from the carpellary leaves).</p>

+
+<p>This case differs from most that have been recorded, and in which there

+closely to resemble the state of things in the <i>B&aelig;ckea</i>, and which
+occurred in a double hyacinth, wherein both anthers and ovules were
+borne on the same placenta. Probably, though the fact is not stated, the
+ovary of the hyacinth was open; and we are told that the flower was
+double&mdash;that it was, in fact, modified and changed in more organs than
+one; while in the <i>B&aelig;ckea</i> nothing at all unusual was observed till the
+ovary was cut open. The style was present even in those flowers where
+there was no axile placenta; hence in these cases it could not be, as
+Lindley stated it to be in the closely allied <i>Babingtonia</i>, a
+prolongation of the placenta.<a name="FNanchor_184_184" id="FNanchor_184_184"></a><a href="#Footnote_184_184" class="fnanchor">[184]</a></p>

+<p class="caption"> <span class="smcap">Fig.</span> 99.&mdash;Pollen within the ovule of <i>Passiflora</i> (after Salter).</p>
+</div>
+
+<p>In the case of the passion-flower there were various malformations in
+the ovaries, which were all more or<span class='pagenum'><a name="Page_186" id="Page_186">[Pg 186]</a></span> less split open at the distal end,
+indicating a tendency towards dialysis. The pollen-bearing ovules were
+borne on the edges of these ovaries, and presented various intermediate
+conditions between anthers and ovules, commencing at the distal
+extremity of the carpel with a bi-lobed anther, and passing in series to
+the base of the ovary, an antheroid body of ovule-like form, a modified
+ovule containing pollen, an ovule departing from a perfectly natural
+condition only in the development of a few grains of pollen in its
+nucleus, and, finally, a perfect, normal ovule.</p>
+
+<p>In the flowers of the Rose the stamens exhibited almost every
+conceivable gradation between their ordinary form and that of the
+carpels, while some of the ovules contained pollen in greater or less
+abundance. Speaking generally, the most common state of things in these
+flowers was the occurrence on the throat of the calyx, in the position
+ordinarily occupied by the stamens, and sometimes mingled with those
+organs, of twisted, ribbon-like filaments, which bore about the centre
+one or more pendulous, anatropous ovules on their margins. Immediately
+above the latter organs were the anther-lobes, more or less perfectly
+developed, and surmounting these a long style, terminating in a fringed,
+funnel-shaped stigma. Sometimes the ovules were perfect, at other times
+the nucleus protruded through the foramen, while in a third set the
+nucleus was included within the tegument, the ovules having in all
+respects their natural external conformation, containing, however, not
+only pollen-grains, but also a layer of those peculiar spheroidal cells,
+including a fibrous deposit, which are among the normal constituents of
+the anther. In one case, where the coat of the ovule was imperfect, and
+allowed the nucleus to protrude, the pollen was evidently contained
+within the central mass of the structure. In this instance the fibrous
+cells were not detected, these being only found in cases where the
+investment of the ovule was perfect; and hence it seems likely that the
+fibrous cells were part of the coat<span class='pagenum'><a name="Page_187" id="Page_187">[Pg 187]</a></span> of the ovule, while the pollen was
+formed within the nucleus. In no case was any trace of embryo sac to be
+seen.</p>
+
+<p>The main interest, as Mr. Salter remarks, in these cases is
+physiological; so far as structure alone is concerned, there does not
+appear any reason why pollen-grains should not be developed in any
+portion of the plant; the mother cells in which the pollen is formed not
+differing, to all outward appearance, from any other cells, unless it be
+in size.</p>
+
+<p>The fundamental unity of construction in all the organs of plants could
+hardly be better illustrated than by these cases; while, in spite of
+their exceptional nature, they must be of great interest
+physiologically, as showing the wide limits of possible variation which
+thus may even involve the sex, "for an ovule to develop pollen within
+its interior," says Mr. Salter, "is equivalent to an ovum in an animal
+being converted into a capsule of spermatozoa. It is a conversion of
+germ into sperm, the most complete violation of individuality and unity
+of sex. * * * * The occurrence of an antheroid ovule and a normal ovule
+on the same carpellary leaf realises the simplest and the most absolute
+form of hermaphroditism."</p>
+
+<p>It must, however, be remarked that the term substitution would be
+preferable to conversion. There is, at present, no evidence to show that
+the germinal vesicles were present in these cases; on the other hand, it
+seems most probable that they were not, so that the presence of the
+pollen-cells must be considered as simply adventitious. It can hardly be
+that they were, in the first instance, germinal vesicles, which, in
+course of time, became so modified as to assume the appearance of
+pollen-grains. Between the nucleus of the ovule and the tubercle of
+cellular tissue constituting the primordial anther, there is little or
+no difference, so that it may be said that, for a time, there is no
+distinction of sex in the nascent flower, but as development goes on,
+the difference becomes perceptible.<span class='pagenum'><a name="Page_188" id="Page_188">[Pg 188]</a></span> It cannot at present be stated what
+precise circumstances induce the one mass to form mother-cells and
+pollen-grains, and the other to develop an embryo sac and germinal
+vesicles. Position and external circumstances may have some indirect
+effect, and it may, perhaps, be significant that in all the instances of
+polliniferous ovules, the ovular structures have been exposed on an open
+carpel or otherwise, in place of being confined within the cavity of a
+closed ovary, as under ordinary circumstances. Even among Conifers the
+ovuligerous scales are so closely packed that there is little or no
+exposure of the ovules. But, apart from all speculative notions as to
+the relation between the structure and functions of the anther and of
+the ovule respectively, and of the possibility or the reverse of
+parthenogenesis, it will clearly be necessary in any future alleged
+occurrence of the latter phenomenon to ascertain whether any or all of
+the apparent ovules are, or are not, anthers in disguise.</p>
+
+
+
+<p><b>Homomorphic flowers of "Composit&aelig;."</b>&mdash;In a large section of the
+<i>Composit&aelig;</i> there is, as is well known, a distinction between the
+florets of the "disc" and those of the "ray," the latter being ligulate,
+the former tubular.</p>
+
+<p>In what are erroneously called double flowers in this order, <i>e.g.</i> in
+the Chrysanthemum, Dahlia, &amp;c. &amp;c., the florets are all ligulate. This
+change is sometimes classed with peloria, but there is no abnormal
+regularity in these cases. On the other hand, were the ligulate florets
+to be all replaced by tubular ones, the term peloria would be more
+strictly applicable. It will be remembered that in the sub-order
+<i>Liguliflor&aelig;</i>, the florets are naturally all ligulate, so that the
+change above mentioned is not in itself a very grave one.</p>
+
+
+
+<p><b>Heterotaxy affecting the inflorescence.</b>&mdash;Under the head of
+Prolification, Heterogamy, &amp;c., various deviations from the normal
+inflorescence are alluded to. In this place, therefore, it is only
+necessary to mention certain rare<span class='pagenum'><a name="Page_189" id="Page_189">[Pg 189]</a></span> deviations from the customary
+arrangement of the inflorescence, such as the change from a definite
+centrifugal form of inflorescence to an indefinite centripetal one. This
+occurs occasionally in roses, where the shoot, instead of terminating in
+a flower-bud, lengthens and bears the flower-bud on its sides as in a
+raceme.</p>
+
+<p>In the hyacinth, the inflorescence of which is properly indefinite, the
+terminal flower may frequently be found to expand first, though in order
+of development it may have been the last formed.</p>
+
+<p>It occasionally happens that certain plants will, contrary to their
+usual custom, bloom twice in the same season; this usually arises from
+the premature development of buds which, under ordinary circumstances,
+would not unfold till the following spring. In these instances of what
+the French term "fleuraison anticip&eacute;e," the position of inflorescence is
+not changed, but there are other cases where the position of the
+inflorescence is altered, as in the laburnum, where, in some seasons,
+racemes may be seen springing from short lateral "spurs" along the sides
+of the branches, as well as from the extremities of long shoots.</p>
+
+<p>Of a similar nature are those cases wherein stems or branches usually
+sterile become fertile; this happens in <i>Equisetace&aelig;</i>,<a name="FNanchor_187_187" id="FNanchor_187_187"></a><a href="#Footnote_187_187" class="fnanchor">[187]</a> in
+<i>Restiace&aelig;</i>, and other orders. In the equisetums, the condition in
+question has been specially noticed to occur after prolonged drought.</p>
+
+<p><i>Equisetace&aelig;</i> are likewise subject to an anomaly called by Duval Jouve
+interruption of the spike, and wherein the scales bearing the spore
+cases are separated by whorls of branches instead of forming one compact
+unbroken spike as usual.</p>
+
+<p>This alternation of the organs of vegetation and reproduction may also
+be seen occasionally in <i>Typha</i>, and other plants.</p>
+
+<p>Kirschleger describes a case in which the male catkins of <i>Salix
+cinerea</i> were placed at the ends of the<span class='pagenum'><a name="Page_190" id="Page_190">[Pg 190]</a></span> branches instead of being
+lateral productions; moreover the usual articulation was not formed, so
+that the catkin was persistent instead of deciduous.<a name="FNanchor_188_188" id="FNanchor_188_188"></a><a href="#Footnote_188_188" class="fnanchor">[188]</a></p>
+
+
+
+<p><b>Supra-soriferous ferns.</b>&mdash;In the great majority of ferns the sori or
+clusters of spore cases are placed on the under surface of the fronds;
+nevertheless, a few cases are on record where the fructification is
+produced on the upper as well as on the lower surface, and sometimes
+abundantly so. This occasionally happens from the elongation of the
+normally placed sorus, which thus extends to the margin, and returns on
+the upper side, when the sori chance to be placed opposite to the
+marginal crenatures. But it is also frequently the case that the sori
+are produced on the upper side, distinctly within the margin, and where
+there are no corresponding sori beneath. Those varieties which have the
+margin crenated or lobed seem most liable to assume this abnormal
+supra-soriferous condition. Among the ferns in which this condition has
+been observed are the following: <i>Scolopendrium vulgare</i>, <i>Polypodium
+anomalum</i>, Hook., <i>Asplenium Trichomanes</i>, <i>Cionidium Moorei</i>.<a name="FNanchor_189_189" id="FNanchor_189_189"></a><a href="#Footnote_189_189" class="fnanchor">[189]</a></p>

+
+HETEROGAMY.</h4>
+
+
+<p>This term is here intended to apply to all those cases in which the
+arrangement of the sexual organs is different from what it is
+habitually. It is evident that in many instances there is no
+malformation, no monstrosity, but rather a restoration of organs
+habitually<span class='pagenum'><a name="Page_191" id="Page_191">[Pg 191]</a></span> suppressed, a tendency towards structural completeness
+rather than the reverse. It must be also understood that the following
+remarks apply to structural points only, and are not intended to include
+the question of function. The occurrence of heteromorphic unions renders
+it necessary to keep in mind that plants hermaphrodite as to structure
+are by no means necessarily so as to function.</p>
+
+<p>The simplest case of this alteration in the relative position of the
+sexes is that which occurs in mon&oelig;cious plants, where the male and
+female flowers have a definite position, but which in exceptional
+instances is altered.</p>
+
+
+
+<p><b>Change in the relative position of male and female flowers</b> may thus
+occur in any mon&oelig;cious plant. Cultivated maize, <i>Zea Mays</i>,
+frequently exhibits alterations of this kind; under ordinary
+circumstances, the male inflorescence is a compound spike, occupying the
+extremity of the stem, while the female flowers are borne in simple
+spikes at a lower level, but specimens may now and then be found where
+the sexes are mixed in the same inflorescence; the upper branching
+panicle usually containing male flowers only, under these circumstances,
+bears female flowers also.<a name="FNanchor_190_190" id="FNanchor_190_190"></a><a href="#Footnote_190_190" class="fnanchor">[190]</a> In like manner, but less frequently, the
+female inflorescence occasionally produces male flowers as well.</p>
+
+<p>Among the species of <i>Carex</i> it is a common thing for the terminal spike
+to consist of male flowers at the top, and female flowers at the base;
+the converse of this, where the female flowers are at the summit of the
+spike, is much more uncommon. An illustration of this occurrence is
+given in the figure (fig. 100). Among the <i>Conifer&aelig;</i> numerous instances
+have been recorded of the presence of male and female flowers on the
+same spike, thus Mr. now Professor Alexander Dickson exhibited at the
+Botanical Society of Edinburgh<span class='pagenum'><a name="Page_192" id="Page_192">[Pg 192]</a></span> in July, 1860, some malformed cones of
+<i>Abies excelsa</i>, in which the inferior part of the axis was covered with
+stamens, whilst the terminal portion produced bracts and scales like an
+ordinary female cone. The stamens of the lower division were serially
+continuous with the bracts above. Some of the lower scales of the female
+portion were in the axils of the uppermost stamens, which last were
+somewhat modified, the anther cells being diminished, whilst the
+scale-like crest had become more elongated and pointed, in fact, more or
+less resembling the ordinary bracts.<a name="FNanchor_191_191" id="FNanchor_191_191"></a><a href="#Footnote_191_191" class="fnanchor">[191]</a> Mohl, Schleiden, and A. Braun
+have observed similar cones in <i>Pinus alba</i>, and Cramer figures and
+describes androgynous cones in <i>Larix microcarpa</i>. C. A. Meyer ('Bull.
+Phys. Math.,' t. x, 1850) also describes some catkins of <i>Alnus
+fruticosa</i> which bore male flowers at the top, and female flowers at the
+base.</p>

+<p><b>Change from the mon&oelig;cious to the di&oelig;cious condition.</b>&mdash;This is of
+less frequent occurrence than might have been anticipated. In the
+'Gardeners' Chronicle,' 1847, pp. 541 and 558, several instances are
+noted of walnut trees bearing female flowers to the exclusion of males.
+The mulberry tree has also been noticed to produce female blossoms only,
+while in other plants male flowers only are developed.</p>
+
+<p>It seems probable that the age of the plant may have something to do
+with this production of flowers of one sex to the exclusion of the
+other.</p>
+
+
+
+<p><b>Change from the di&oelig;cious to the mon&oelig;cious

+</div>
+
+<p>In the hop (<i>Humulus Lupulus</i>), when mon&oelig;cious, the female catkins
+are usually borne on the ends of the branches as shown in the cut (fig.
+101), and a similar<span class='pagenum'><a name="Page_194" id="Page_194">[Pg 194]</a></span> thing has been noticed in <i>Urtica dioica</i> by Clos,
+'Bull. Soc. Bot. France,' vol. 9, p. 7.</p>
+
+<p>Baillon ('Etudes du groupe des Euphorbiac&eacute;es,' p. 205) mentions the
+following species of that order as having been seen by him with
+mon&oelig;cious inflorescence: <i>Schismatopera distichophylla</i>, <i>Mozinna
+peltata</i>, <i>Hermesia castaneifolia</i>. Oliver mentions ('Hook. Icon.
+Plant.,' t. 1044) that in <i>Leitneria floridana</i> the upper scales of the
+male catkin occasionally subtend an ovary.</p>
+
+<p>It would seem that external conditions have some effect in determining
+the formation of one sex, as in some species of <i>Carex</i>, while in the
+case of <i>Salix repens</i>, Hampe<a name="FNanchor_192_192" id="FNanchor_192_192"></a><a href="#Footnote_192_192" class="fnanchor">[192]</a> says that when grown partially or for
+a time under water, those twigs which are thrust up above the surface
+bear female flowers, while those twigs that blossom after the water is
+dried up, produce male flowers only.</p>
+
+<p>Carri&egrave;re<a name="FNanchor_193_193" id="FNanchor_193_193"></a><a href="#Footnote_193_193" class="fnanchor">[193]</a> says that a plant of <i>Stauntonia latifolia</i> which for some
+years produced stamens only, now produces flowers of both sexes; it was
+di&oelig;cious, but is now mon&oelig;cious. The same author alludes to a
+similar occurrence in <i>Juniperus Virginiana</i>. The <ins title="nutmeg in original">hops</ins> is also said to
+vary in sexual characteristics from time to time.<a name="FNanchor_194_194" id="FNanchor_194_194"></a><a href="#Footnote_194_194" class="fnanchor">[194]</a> In addition to
+the genera, already named, in which this production of flowers of both
+sexes has been observed may be mentioned <i>Taxus! Gunnera! Urtica!
+Mercurialis! Restio! Cannabis! Salix! Humulus!</i> as well as others in
+which the change is less frequent.</p>
+
+<p>Among cryptogams a similar change occurs. As an illustration may be

+'Botanical Gazette,' i, p. 100.</p>

+
+<p><b>Change from hermaphroditism to unisexuality.</b>&mdash;Many flowers ordinarily
+hermaphrodite as to structure, become unisexual by the abortion or
+suppression of their stamens, or of their carpels, as the case may be.
+This phenomenon is lessened in interest since the demonstration of the
+fact by Darwin and others, that many plants, structurally hermaphrodite,
+require for the full and perfect performance of their functions the
+cooperation of the stamens and pistils, belonging to different
+individuals of the same species.</p>
+
+<p>Some of the <i>Ranunculace&aelig;</i> constantly exhibit a tendency towards the
+di&oelig;cious condition, and the rarity with which perfect seeds of
+<i>Ranunculus Ficaria</i> are formed is to be attributed, in great measure,
+to the deficiency of pollen in the anthers of these flowers. <i>Ranunculus
+auricomus</i> also is frequently sterile. Specimens of <i>Ranunculus
+bulbosus</i> may be met with in which every flower is furnished with
+carpels, most of which have evidently been fertilised, although there
+are no perfect stamens in the flowers.</p>
+
+<p>Knight and other vegetable physiologists have been of opinion that a
+high temperature favours the production of stamens, while a lower degree
+of heat is considered more favorable to the production of pistils, and
+in this way the occurrence of "blind" strawberries has been accounted
+for. Mr. R. Thompson, writing on this subject, speaks of a plantation of
+Hautbois strawberries which in one season were wholly sterile, and
+accounts for the circumstance as follows: the plants were taken from the
+bearing beds the year previous, and were planted in a rich well-manured
+border, in which they started rapidly into too great luxuriance, the
+growth being to leaves rather than to fruit. The following season these
+same plants bore<span class='pagenum'><a name="Page_196" id="Page_196">[Pg 196]</a></span> a most abundant crop, hence these plants were
+accidentally prevented from perfecting their female organs.<a name="FNanchor_195_195" id="FNanchor_195_195"></a><a href="#Footnote_195_195" class="fnanchor">[195]</a></p>
+
+<p>Mr. Darwin<a name="FNanchor_196_196" id="FNanchor_196_196"></a><a href="#Footnote_196_196" class="fnanchor">[196]</a> cites from various sources the following details
+relating to strawberries which it may be useful to insert in this place,
+as throwing some light upon the production of unisexual flowers.
+"Several English varieties, which in this country are free from any such
+tendency, when cultivated in rich soils under the climate of North
+America commonly produce plants with separate sexes. Thus, a whole acre
+of Keen's seedlings in the United States has been observed to be almost
+sterile in the absence of male flowers; but the more general rule is,
+that the male plants over-run the females.... The most successful
+cultivators in Ohio plant, for every seven rows of pistillate flowers,
+one row of hermaphrodites, which afford pollen for both kinds; but the
+hermaphrodites, owing to their expenditure in the production of pollen,
+bear less fruit than the female plants."</p>
+
+<p><i>Stratiotes aloides</i> has been said to produce its carpels with greater
+abundance towards the northern limits of its geographical distribution,
+and its stamens, on the other hand, are stated to be more frequently
+developed in more southern districts.</p>
+
+<p><i>Honckenya peploides</i> affords another illustration of the sexual
+arrangements in the flower being altered as it would seem by climatal
+conditions. Thus, in the United States, according to Professor Asa Gray,
+the flowers are frequently hermaphrodite, while in this country they are
+usually sub-di&oelig;cious.<a name="FNanchor_197_197" id="FNanchor_197_197"></a><a href="#Footnote_197_197" class="fnanchor">[197]</a></p>

+
+
+
+<p><b>Change from unisexuality to hermaphroditism.</b>&mdash;This occurrence depends on
+one of two causes, either organs are developed (stamens or pistils as
+the case may be), which are habitually absent in the particular flower;
+or some of the stamens may be more or less completely converted into or
+replaced by pistils, or <i>vice vers&acirc;</i>.</p>
+
+<p>The first condition is the opposite of suppression; it is, as it were, a
+restoration of symmetry, and might be included under the head of regular
+peloria, inasmuch as certain organs which habitually undergo suppression
+at a certain stage in their development, by exception, go on growing,
+and produce a perfect, instead of an imperfect flower. In teratological
+records it is not always stated clearly to which of the two above-named
+causes the unusual hermaphroditism belongs, though it is generally easy
+to ascertain this point. Very many, perhaps all, diclinous flowers may,
+under certain conditions, become perfect, at least structurally. I have
+myself seen hermaphrodite flowers in <i>Cucurbita</i>,<a name="FNanchor_199_199" id="FNanchor_199_199"></a><a href="#Footnote_199_199" class="fnanchor">[199]</a> <i>Mercurialis</i>,
+<i>Cannabis</i>, <i>Zea Mays</i>, and <i>Aucuba japonica</i>, as well as in many
+<i>Restiace&aelig;</i>, notably <i>Cannamois virgata</i> and <i>Lepyrodia hermaphrodita</i>.
+<i>Spinacia oleracea</i>, <i>Rhodiola rosea</i>, <i>Cachrys taurica</i>, and <i>Empetrum
+nigrum</i> are also occasionally hermaphrodite.</p>
+
+<p>Gubler<a name="FNanchor_200_200" id="FNanchor_200_200"></a><a href="#Footnote_200_200" class="fnanchor">[200]</a> alludes to a similar occurrence in <i>Pistacia Lentiscus</i>,
+wherein, however, he adds that there was a deficiency of pollen in the
+flowers.</p>
+
+<p>Schnizlein<a name="FNanchor_201_201" id="FNanchor_201_201"></a><a href="#Footnote_201_201" class="fnanchor">[201]</a> observed hermaphrodite flowers in the beech, <i>Fagus
+sylvatica</i>, the ovaries being smaller than usual, and the stamens
+epigynous.</p>
+
+<p>Baillon<a name="FNanchor_202_202" id="FNanchor_202_202"></a><a href="#Footnote_202_202" class="fnanchor">[202]</a> enumerates the following <i>Euphorbiace&aelig;</i> as having
+exceptionally produced hermaphrodite flowers,<span class='pagenum'><a name="Page_198" id="Page_198">[Pg 198]</a></span> <i>Crozophora tinctoria</i>,
+<i>Suregada</i> sp., <i>Phyllanthus longifolius</i>, <i>Breynia</i> sp., <i>Philyra
+brasiliensis</i>, <i>Ricinus communis</i>, <i>Conceveiba macrophylla</i>, <i>Cluytia
+semperflorens</i>, <i>Wall</i>, non <i>Roxb</i>. <i>Mercurialis annua</i> and
+<i>Cleistanthus polystachyus</i>.</p>
+
+<p>In some of these cases the hermaphroditism is due to the development of
+anthers on the usually barren staminodes, though, in other cases, the
+stamens would seem to be separate, independent formations, as they do
+not occupy the same relative position that the ordinary stamens would do
+if developed.<a name="FNanchor_203_203" id="FNanchor_203_203"></a><a href="#Footnote_203_203" class="fnanchor">[203]</a></p>

+and Gay is stated by Moquin ('El. Ter.<span class='pagenum'><a name="Page_199" id="Page_199">[Pg 199]</a></span> Veg.,' p. 343) to have observed

+<p>Paasch<a name="FNanchor_205_205" id="FNanchor_205_205"></a><a href="#Footnote_205_205" class="fnanchor">[205]</a> observed a similar occurrence in <i>C. c&aelig;spitosa</i>, and

+seems to have been one of transformation or substitution rather than one
+of hermaphroditism.</p>
+
+<p>The second cause of this pseudo-hermaphroditism is due either to the
+more or less perfect mutation of male and female organs, or it may be to
+the complete absence of one and its replacement by another, as when out
+of many stamens, one or more are deficient, and their places occupied by
+carpels. This happens very frequently in willows and poplars, and has

+
+ALTERATIONS IN THE DIRECTION OF ORGANS.</h4>
+
+
+<p>The deviations from the ordinary direction of organs partake for the
+most part more of the nature of variations than of absolute malposition
+or displacement. It must also be borne in mind how frequently the
+direction of the leaves, or of the flower, varies according to the<span class='pagenum'><a name="Page_202" id="Page_202">[Pg 202]</a></span>
+stage of development which it has arrived at, to unequal or
+disproportionate growth of some parts, or to the presence of some
+impediment either accidental or resulting from the natural growth of the
+plant. These and other causes tend to alter the direction of parts very
+materially.</p>
+
+
+
+<p><b>Change in the direction of axile organs, roots, stems, &amp;c.</b>&mdash;The roots
+frequently exhibit good illustrations of the effect of the causes above
+mentioned in altering the natural direction. The roots are put out of
+their course by meeting with any obstacle in their way. Almost the only
+exception to the rule in accordance with which roots descend under
+natural circumstances, is that furnished by <i>Trapa natans</i>, the roots of
+which in germination are directed upwards towards the surface of the
+water. So in <i>Sechium edule</i>, the seed of which germinates while still
+in the fruit, the roots are necessarily, owing to the inverted position
+of the embryo, directed upwards in the first instance.</p>
+
+<p>A downward direction of the stem or branches occurs in many weak-stemmed
+plants growing upon rocks or walls, or in trees with very long slender
+branches as in <i>Salix Babylonica</i>, and the condition may often be
+produced artificially as in the weeping ash.</p>
+
+<p>The opposite change occurs in what are termed fastigiate varieties,
+where the branches, in place of assuming more or less of a horizontal
+direction, become erect and nearly parallel with the main stem as in the
+Lombardy poplar, which is supposed to be merely a form of the black
+Italian poplar.</p>
+
+<p>M. de Selys-Longchamps has described a similar occurrence in another
+species of Poplar (<i>P. virginiana</i> Desf.), and amongst a number of
+seedling plants fastigiate varieties may frequently be found, which may
+be perpetuated by cuttings or grafts, or sometimes even by seed; hence
+the origin of fastigiate varieties of elms, oaks, thorns, <ins title="chesnuts in original">chestnuts</ins>, and
+other plants which may be met with in the nurseries.</p><p><span class='pagenum'><a name="Page_203" id="Page_203">[Pg 203]</a></span></p>
+
+<p>Sometimes when the top of the main stem is destroyed by disease or
+accident, one of the heretofore lateral shoots takes its place, and
+continues the development of the tree in the original direction. It is
+often an object with the gardener to restore the symmetry of an injured
+tree so that its beauty may ultimately not be impaired.<a name="FNanchor_210_210" id="FNanchor_210_210"></a><a href="#Footnote_210_210" class="fnanchor">[210]</a></p>
+
+<p>Climate appears sometimes to have some influence<span class='pagenum'><a name="Page_204" id="Page_204">[Pg 204]</a></span> on the direction of
+branches, thus Dr. Falconer, as quoted by Darwin,<a name="FNanchor_211_211" id="FNanchor_211_211"></a><a href="#Footnote_211_211" class="fnanchor">[211]</a> relates that in
+the hotter parts of India "the English Ribston-pippin apple, a Himalayan
+oak, a Prunus and a Pyrus all assume a fastigiate or pyramidal habit,
+and this fact is the more interesting as a Chinese tropical species of
+<i>Pyrus</i> naturally has this habit of growth. Nevertheless many of the
+fastigiate varieties seen in gardens have originated in this country by
+variation of seeds or buds."</p>
+
+<p>M. Carri&egrave;re has also recorded a curious circumstance with reference to
+the fastigiate variety of the false acacia <i>Robinia pseudacacia</i>; he
+states that if a cutting or a graft be taken from the upper portion of
+the tree, the fastigiate habit will be reproduced, and the branches will
+be furrowed and covered with short prickles; but if the plant be
+multiplied by detaching portions of the root-stock, then instead of
+getting a pyramidal tree with erect branches, a spreading bushy shrub is
+produced, with more or less horizontal, cylindrical branches, destitute
+of prickles.<a name="FNanchor_212_212" id="FNanchor_212_212"></a><a href="#Footnote_212_212" class="fnanchor">[212]</a></p>
+
+
+
+<p><b>Eversion of the axis.</b>&mdash;In the case of the fig, the peculiar
+inflorescence is usually explained on the supposition that the
+termination of the axis becomes concave, during growth, bearing the true
+flowers in the hollow thus formed. The cavity in this case would
+probably be due not to any real process of excavation, but to a
+disproportionate growth of the outer as contrasted with the central
+parts of the fig. Some species of <i>Sempervivum</i> have a similar mode of
+growth, so that ultimately a kind of tube is formed, lined by the
+leaves, the central and innermost being the youngest. The hip of the
+Rose may be explained in a similar manner by the greater proportionate
+growth of the outer as contrasted with the central portions of the apex
+of the flower-stalk. In cases of median prolification, already referred
+to, the process is reversed, the central portions<span class='pagenum'><a name="Page_205" id="Page_205">[Pg 205]</a></span> then elongate into a
+shoot and no cavity is formed. A fig observed by Zuccarini (figs. 105,
+106) appears to have been formed in a similar manner, the flower-bearing
+summit of the stalk not being contracted as usual, the flowers projected
+beyond the orifice of the fig. If this view be correct the case would be
+one rather of lengthening of the axis than of absolute eversion since it
+was never inverted.</p>

+
+
+
+<p><b>Altered direction of leaves.</b>&mdash;The leaves partake more or less of the
+altered direction of the axis, as in fastigiate elms, but this is not
+universally the case, for though the stem is bent downwards the leaves
+may be placed in the opposite direction; thus in some specimens of
+<i>Galium Aparine</i> growing on the side of a cliff from which there had
+been a fall of chalk, the stems, owing apparently to the landslip, were
+pendent, but the leaves were abruptly bent upwards.</p>
+
+<p>One of the most singular instances of an inverted<span class='pagenum'><a name="Page_206" id="Page_206">[Pg 206]</a></span> direction of the
+leaves is that presented by a turnip (fig. 107) presented to the Museum
+of King's College, London, by the late Professor Edward Forbes. The
+turnip is hollow in the interior and the majority of the leaves
+springing from its apex instead of ascending into the light and air
+become bent downwards so as to occupy the cavity, and in such a manner
+as to bring to mind the position of an inverted embryo in a seed.</p>

+
+
+
+<p><b>Altered direction of the flower and its parts.</b>&mdash;The changes which take
+place in the relative position either of the flower as a whole or of its
+several parts during growth are well known, as also are the relations
+which some of these movements bear to the process of fertilisation, so
+that but little space need here be given to the subject beyond what is
+necessary to point out the frequent changes of direction which
+necessarily accompany<span class='pagenum'><a name="Page_207" id="Page_207">[Pg 207]</a></span> various deviations from the ordinary form and
+arrangement of parts.</p>
+
+<p>In cases where an habitually irregular flower becomes regular, the
+change in form is frequently associated with an alteration in direction
+both of the flower as a whole and, to a greater or less extent, of its
+individual members, for instance of <i>Gloxinia</i>, the normal flowers of
+which are irregular and pendent, there is now in common cultivation a
+peloriate race in which the flowers are regular in form and erect in
+position.</p>

+<p>Fig. 109 shows the regular erect form; fig. 110 the calyx of the same
+flower; while in fig. 111 are shown the stamens and style of the two
+plants respectively. In the upper figure the style of the peloriate
+variety is shown as nearly straight, and the stamens undergo a
+corresponding change. No doubt the relative fertility and capacity for
+impregnation of the two varieties is affected in proportion to the
+change of form. The Gloxinia affords an instance of regular congenital
+peloria in which the regularity of form and the erect direction are due
+to an arrest, not of growth, but of development, in consequence of which
+the changes that ordinarily ensue during the progress of the flower from
+its juvenile to its fully formed condition do not take place.</p>

+
+<p>A similar alteration accompanies this form of peloria in other flowers
+(see Peloria). A change in direction may result also from other
+circumstances than those just alluded to. Abortion or suppression of
+organs will induce such an alteration; thus in a flower of <i>Pelargonium</i>
+now before me three of the five carpels, from some cause or other, are
+abortive and much smaller than usual, and the style and the beak-like<span class='pagenum'><a name="Page_209" id="Page_209">[Pg 209]</a></span>
+torus are bent downwards towards the stunted carpels instead of being,
+as they usually are, straight.</p>
+
+<p>Amongst orchids, where the pedicel of the flower or the ovary is
+normally twisted, so that the labellum occupies the anterior or inferior
+part of the flower, it frequently happens, in cases of peloria and other
+changes, that the primitive position is retained, the twist does not
+take place, and so with other resupinate flowers. In Azaleas a curious
+deflexion of the parts of the flower may occasionally be met with. Fig.
+112 shows an instance of this in which the corolla, the stamens and the
+style were abruptly bent downwards: as young flowers of this singular
+variety have not been examined it is difficult to form an opinion as to
+the cause of this variation. In one plant the change occurred in
+connection with the suppression of all the flowers but one in the
+cluster, or rather the place of the flowers was occupied by an equal
+number of leafy shoots.</p>

+customary parchment-like carpels, the smaller was destitute of them.</p>
+
+<p>Sometimes the direction assumed by one flower as an abnormal occurrence

+<div class="footnote"><p><a name="Footnote_210_210" id="Footnote_210_210"></a><a href="#FNanchor_210_210"><span class="label">[210]</span></a> The following details as to the method pursued by Mr.
+McNab, of the Edinburgh Botanic Garden, may not be uninteresting in this
+place. They are from the pen of Mr. Anderson, and originally appeared in
+the 'Gardeners' Chronicle.'
+</p><p>
+"The mode of inducing leaders to proceed from laterals is a matter of
+comparatively little concern among the generality of deciduous trees,
+for they are often provided with subsidiary branches around the leader,
+at an angle of elevation scarcely less perpendicular, but the laterals
+of all Conifers stand, as nearly as possible, at right angles. Imagine
+the consternation of most people when the leader of, say, <i>Picea
+nobilis</i>, <i>P. Nordmanniana</i>, or <i>P. Lowii</i> is destroyed."
+</p><p>
+In a specimen of the latter plant the leader had been mischievously
+destroyed, to remedy which Mr. McNab adopted means which Mr. Anderson
+goes on to describe. "Looking from the leader downward to the first tier
+of laterals, there appeared to have been a number of adventitious
+leaf-buds created, owing to the coronal bud being destroyed. These were
+allowed to plump up unmolested until the return of spring, when every
+one was scarified or rubbed off but the one nearest the extremity. To
+assist its development and restrain the action of the numerous laterals,
+every one was cut back in autumn, and this restraint upon the sap acted
+so favorably upon the incipient leader as to give it the strength and
+stamina of the original leader, so that nothing detrimental was evident
+twelve months after the accident had happened, and only a practical eye
+could detect that there had been any mishap at all. This beautifully
+simple process saved the baby tree.
+</p><p>
+"Another example of retrieving lost leaders may be quoted as
+illustrative of many in similar circumstances. <i>P&iacute;cea Webbiana</i> had its
+leader completely destroyed down to the first tier of laterals. There
+was no such provision left for inducing leaf-buds as was the case with
+<i>P. Lowii</i> above referred to. Resort must, therefore, be had to one of
+the best favoured laterals, but how is it to be coaxed from the
+horizontal position of a lateral to the perpendicular position of a
+leader? The uninitiated in these matters, and, in fact, practical
+gardeners generally, would at once reply, by supporting to a stake with
+the all-powerful Cuba or bast-matting. But no. A far simpler method than
+that, namely, by fore-shortening all the laterals of the upper tier but
+the one selected for a leader. Nature becomes the handmaid of art here;
+for without the slightest prop the lateral gradually raises itself
+erect, and takes the place of the lost leader. All that the operator
+requires to attend to is the amputation of the laterals until this
+adventitious fellow has gained a supremacy. Singular provision in nature
+this, which, thanks to the undivided attention of a careful observer,
+has been fully appreciated and utilized."</p></div>

+
+DEVIATIONS FROM THE ORDINARY FORM OF ORGANS.</h2>
+
+
+<p>In a morphological point of view the form of the various parts or organs
+of plants and the changes to which they are subjected during their
+development are only second in importance to the diversities of
+arrangement and, indeed, in some cases, do not in any degree hold a
+second place.</p>
+
+<p>Taken together, the arrangement, form, and number of the several parts
+of the flower, make up what has been termed the symmetry of the
+flower.<a name="FNanchor_217_217" id="FNanchor_217_217"></a><a href="#Footnote_217_217" class="fnanchor">[217]</a> Referring to the assumed standard of comparison, <a href="#Page_4">see p. 4</a>,
+it will be seen that in the typically regular flower all the various
+organs are supposed to be regular in their dimensions and form. At one
+time it was even supposed that all flowers, no matter how irregular
+they<span class='pagenum'><a name="Page_214" id="Page_214">[Pg 214]</a></span> subsequently became, began by being strictly symmetrical or
+regular, and that subsequent alterations were produced by inequality of
+growth or development. The researches of organogenists have, however,
+dispelled this idea of unvarying primordial regularity, by showing that
+in many cases flowers are irregular from the very first, that some begin
+by being irregular, and subsequently become regular, and even in some
+cases resume their original condition during the course of their
+development.<a name="FNanchor_218_218" id="FNanchor_218_218"></a><a href="#Footnote_218_218" class="fnanchor">[218]</a> Under these circumstances an artificial standard of
+comparison becomes almost an absolute necessity for the time being.</p>
+
+<p>Changes of form very generally, but not always, are accompanied with a
+change in regularity: thus a flower habitually bi-lateral may assume the
+characters of radiating symmetry and <i>vice vers&acirc;</i>. Increase or decrease
+of size very frequently also are co-existent with an alteration in the
+usual form.</p>
+
+<p>In the case of the arrangement of organs it is often difficult or
+impossible, in the present state of our knowledge, to determine whether
+a given arrangement is congenital or acquired subsequently to the first
+development, whether for instance an isolation of parts be due to
+primordial separation or to a subsequent disunion of originally combined
+organs, <a href="#Page_58">see p. 58</a>. With reference to the changes in the form of organs,
+however, it is in general more easy to ascertain the proximate cause of
+the appearance, and thus teratological changes of form may be grouped
+according as they are due to, 1, arrest of development; 2, undue or
+excessive development; 3, perverted development; and 4, irregular
+development; hence the use of the following<span class='pagenum'><a name="Page_215" id="Page_215">[Pg 215]</a></span> terms&mdash;Stasimorphy,
+Pleiomorphy, Metamorphy, and Heteromorphy&mdash;to include teratological
+changes really or apparently due to one or other of the causes above
+mentioned. The classification here adopted is of course to a
+considerable extent an arbitrary one and subject to correction or
+modification, as the knowledge of the development of the flowers in the
+various genera of plants advances.</p>

+(bi-lateral symmetry). Others, again, have applied the term symmetry to
+the number of the parts of the flower, reserving the terms "regularity"

+
+
+<p>Deviations from the ordinary form of organs arising from stasis or
+arrest of development are included under this heading.</p>
+
+<p>There are many cases in which the forms proper to a juvenile condition
+of the plant are retained for a much longer period than ordinary, or
+even throughout the life of the individual growth goes on, but
+"development" is checked. Such conditions may even be propagated by seed
+or bud. It is a very general thing for botanists to consider these cases
+as reversions to a simpler, primitive type, and this may be so; but on
+the other hand, they may be degenerations from a complex type, or they
+may have no direct relation to any antecedent condition. Stasimorphic
+changes affecting principally the relative size of organs&mdash;such, for
+instance, as the non-development of internodes, or the atrophy or
+suppression of parts will be found mentioned in the sections relating to
+those subjects. In the present part those alterations which affect the

+PERSISTENCE OF JUVENILE FORMS.</h4>
+
+
+<p>The retention in adult life of a form characteristic of an early stage
+of development, and therefore usually transient, may be manifested in
+any of the organs of the plant. As these cases are for the most part
+treated under separate headings, it is here only necessary to allude to
+a few, which it is difficult to allocate satisfactorily, while the
+reader may be referred for other instances of like nature to the
+sections on Peloria, Atrophy, Suppression, Dimorphy, Substitutions, &amp;c.</p>

+produced in the young state of the plant are different, both in
+arrangement and form, from those subsequently developed (<a href="#Page_89">see pp. 89</a>,
+90). But it<span class='pagenum'><a name="Page_218" id="Page_218">[Pg 218]</a></span> occasionally happens that the plant continues to form
+throughout its existence leaves such as are usually produced only in a
+young state; thus M. Gubler ('Bull. Soc. Bot., Fr.,' vol. viii, 1861, p.
+527) describes a plant of <i>Pinus pinea</i> in which the primordial, usually
+transitory, foliage was permanent, leaves of the ordinary shape not
+being developed at all. It more often happens that some only of the
+leaves retain their young form while others assume other shapes, see
+fig. 115. This happens frequently in the larch and constantly in the
+Chinese juniper when it has arrived at a considerable age. In <i>Cupressus
+funebris</i> two forms of leaves may often be found on the same plant, the
+one representing the juvenile state, the other the more developed
+condition. What is very singular, is that a cutting taken from the
+branch with leaves of the young form grows up into a shrub bearing
+leaves of no other shape, so that an ordinary observer unacquainted with
+the history of the plant would imagine that he had to deal with two
+distinct species. This fact is the more interesting when compared with
+the alternation of generations which takes place among the lower
+animals.</p>
+
+<p>The regular development of all the parts of the flower in a plant
+habitually producing irregular flowers is referred to under the head of
+Peloria, but it still remains to consider those examples in which some
+only of the parts of the flower are affected in this manner.<a name="FNanchor_220_220" id="FNanchor_220_220"></a><a href="#Footnote_220_220" class="fnanchor">[220]</a> Most
+of these cases are elsewhere referred to in this volume under the
+particular form of malformation assumed; but the following case may here
+be noticed as not coming under any of the previous heads. It is an
+instance recorded by Professor Babington ('Phytologist,' August, 1853),
+and in which the pod of <i>Medicago maculata</i>, which is usually rolled up
+like a snail shell and provided with spines, was sickle-shaped and

+
+<p>When an habitually irregular flower becomes regular, it does so in one
+of two ways; either by the non-development of the irregular portions, or
+by the formation of irregular parts in increased number, so that the
+symmetry of the flower is rendered perfect, as in the original peloria
+of Linn&aelig;us, and which may be called irregular peloria, while the former
+case may be called regular peloria. This latter appearance is therefore
+congenital, and due to an arrest of development.<a name="FNanchor_221_221" id="FNanchor_221_221"></a><a href="#Footnote_221_221" class="fnanchor">[221]</a> As the true nature
+of these cases has not been in all cases recognised (even Moquin places
+them under the head of deformities&mdash;they being less entitled to rank in
+that class than are the usual flowers), it may be well to cite a few
+instances taken from various families. In <i>Delphinium peregrinum</i> I have
+met with perfectly regular flowers having five sepals and five oblong
+stalked petals, and a similar occurrence has been noted<span class='pagenum'><a name="Page_220" id="Page_220">[Pg 220]</a></span> in other
+species of this genus. Baillon,<a name="FNanchor_222_222" id="FNanchor_222_222"></a><a href="#Footnote_222_222" class="fnanchor">[222]</a> in referring to these flowers,
+points out the resemblance that they bear to the double varieties of
+<i>Nigella</i>. In the stellate columbines (<i>Aquilegia</i>) of gardens the
+tubular petals are replaced by flat ones often in increased numbers. In
+violets both forms of peloria occur, that in which there is an unusual
+number of spurs, and that in which there are no spurs (var. anectaria).
+In the more perfect forms of regular peloria occurring in the last-named
+genus the following changes may be noticed: 1, an alteration in the
+direction of the flower so that it remains in an erect position, and is
+not bent downwards as usual; 2, equality of proportion in the sepals and
+petals; 3, absence of spurs, as also of<span class='pagenum'><a name="Page_221" id="Page_221">[Pg 221]</a></span> hairs on the lateral petals; 4,
+equal stamens whose anthers are sometimes entirely destitute of the
+prolonged crest which forms so prominent a feature under ordinary
+circumstances; 5, erect, not curved styles, and the stigmas not
+prolonged into a beak, but having a more or less capitate form; ovary
+with three or five cells, ovules normal.</p>
+
+<p>These are cases where the change in question is most strongly marked,
+the bi-lateral is completely replaced by the radiating symmetry. The
+absence of the usual nectary, and of hairs on the side petals, the
+alterations in the form of the style, etc., all show how much the
+process of fertilisation must be altered from that which occurs under
+ordinary circumstances. In some of the double violets now cultivated in
+gardens, a similar regularity of proportion in the parts of the flower
+may be seen combined with the substitution of petals for stamens and
+pistils, and with the development of an increased number of petal-like
+organs.<a name="FNanchor_223_223" id="FNanchor_223_223"></a><a href="#Footnote_223_223" class="fnanchor">[223]</a> Between these cases and the ordinary spurred forms as well
+as those with an increased number of spurs, many intermediate forms may
+be met with. That such regularity should occur in this family is not to
+be wondered at seeing that there is a whole subdivision of the order
+(<i>Alsodei&aelig;</i>) in which regular flowers are the rule.</p>
+
+<p>In cultivated Pelargoniums the central flower of the umbel or "truss"
+frequently retains its regularity of proportion, so as closely to
+approximate to the normal condition in the allied genus <i>Geranium</i>; this
+resemblance is rendered greater by the fact that, under such
+circumstances, the patches of darker colour characteristic of the
+ordinary flower are completely wanting; the flower is as uniform in
+colour as in shape. Even the nectary which is adherent to the upper
+surface of the pedicel in the normal flower disappears&mdash;sometimes
+completely, at other tunes partially. The direction of the stamens and
+style, and even that of the whole flower, becomes<span class='pagenum'><a name="Page_222" id="Page_222">[Pg 222]</a></span> altered from the
+inclined to the vertical position. In addition to these changes, which
+are those most commonly met with, the number of the parts of the flower
+is sometimes augmented, and a tendency to pass from the verticillate to
+the spiral arrangement manifested. Schlechtendal mentions some flowers
+of <i>Trop&aelig;olum majus</i> in which the flowers were perfectly regular and
+devoid of spurs<a name="FNanchor_224_224" id="FNanchor_224_224"></a><a href="#Footnote_224_224" class="fnanchor">[224]</a>, while in the double varieties, now commonly grown
+in greenhouses, the condition of parts is precisely the same as in the
+double violet before alluded to. Among the <i>Papilionace&aelig;</i> the Laburnum
+and others have been noticed to produce occasionally a perfectly regular
+flower in the centre, or at the extremity of the inflorescence, though
+the peloria in this flower is usually irregular. In the Gentianaceous
+genus <i>Halenia</i>, <i>H. heterantha</i> is remarkable for the absence of spurs.
+Amongst <i>Gesnerace&aelig;</i>, <i>Bignoniace&aelig;</i>, <i>Scrophulariace&aelig;</i>, and other
+families of like structure, regular peloria is not uncommon. Fig. 120
+represents a case of this kind in <i>Eccremocarpus scaber</i>, conjoined, as
+is frequently the case, with dialysis or separation of the petals.<a name="FNanchor_225_225" id="FNanchor_225_225"></a><a href="#Footnote_225_225" class="fnanchor">[225]</a>
+Many of the cultivated Gloxinias also show<span class='pagenum'><a name="Page_223" id="Page_223">[Pg 223]</a></span> erect, regular, five
+stamened flowers, but these are probably cases of irregular peloria.</p>

+<p>A solitary flower of <i>Pedicularis sylvatica</i> was found by the Marquis of
+Stafford near Dunrobin Castle in Sutherlandshire, in which the usual
+ringent form of the corolla was replaced by the form called
+salver-shaped. There were six stamens, four long and two short. Sir W.

+
+<p>The passage of ligulate to tubular corollas among <i>Composit&aelig;</i> is not of
+such common occurrence as is the converse change. I owe to Mr. Berkeley
+the communication of a capitulum of a species of <i>Bidens</i>, in which
+there was a transition from the form of ligulate corollas to those that
+were deeply divided into three, four, or five oblong lobes. These then
+were instances of regular peloria.</p>

+121, reduced from a cut in the 'Gardeners' Chronicle,' 1854, p. 804,
+represents an instance of this kind in <i>Cattleya marginata</i>.</p>
+
+<p>From the same journal the following account of a case of peloria in
+<i>Phal&aelig;nopsis Schilleriana</i> is also cited as a good illustration of this
+peculiar change. The terminal flower differed entirely from all the
+others; instead of the peculiar labellum there were three petals all
+exactly alike, and three sepals also exactly alike; the petals resembled
+those of the other flowers of the spike, and the upper sepal also; but
+the two lower sepals had no spots, and were not reflexed as in the
+ordinary way: thus, these six parts of the flower were all in one plane,
+and being close together at their edges, made almost a full round
+flower; the column and pollen-glands were unaffected. Professor
+Reichenbach also exhibited at the Amsterdam Botanical Congress, of 1865,
+a flower of <i>Selenipedium caudatum</i> with a flat lip.</p>
+
+<p>M. Gris<a name="FNanchor_227_227" id="FNanchor_227_227"></a><a href="#Footnote_227_227" class="fnanchor">[227]</a> has placed on record some interesting cases of peloria of
+this kind in <i>Zingiber zerumbet</i>; in the more complete forms the
+andr&oelig;cium or staminal series was composed of six distinct pieces, the
+three inner of which were fertile, while in the ordinary flower the
+andr&oelig;cium is composed of two pieces, "a lip" and a fertile stamen.
+"Is it not a matter of regret," says M. Gris, "to be obliged to call the
+latter the normal flower?"</p>
+
+<p>Under this head may likewise be mentioned those cases in which the
+normal, or at least the typical symmetry of the flower is restored by
+the formation of parts usually suppressed; thus Moquin cites an abnormal
+flower of <i>Atriplex<a name="FNanchor_228_228" id="FNanchor_228_228"></a><a href="#Footnote_228_228" class="fnanchor">[228]</a> hortensis</i> described by M. Fenzl as having a
+true calyx within the two bracts that usually alone encircle the
+stamens. Adanson, also cited by Moquin, found a specimen of <i>Bocconia</i>
+with a<span class='pagenum'><a name="Page_225" id="Page_225">[Pg 225]</a></span> corolla. <i>Arum maculatum</i> has likewise been met with provided
+with a genuine perianth as in <i>Acorus</i> and other Orontiads. The unusual
+development of the sexual organs in diclinous flowers has been alluded
+to under the head of heterogamy, and other cases where the symmetry of
+the flower is rendered regular, by the development of parts ordinarily
+suppressed, will be found in the chapters relating to deviations from
+the usual number of organs.</p>
+
+<p>This change, or rather this persistence of a form that is usually
+transient, is generally accompanied by some other alterations. Change of
+direction, as has been already mentioned, is one of the most common of
+these; separation of the petals (<i>Antirrhinum</i>, <i>Verbascum</i>, &amp;c.), and
+even their appearance in leaf-like guise, are not infrequent
+(<i>Delphinium</i>, <i>Antirrhinum</i>, <i>Verbascum</i>, &amp;c.) At other times
+multiplication or increased number of the whorls of petals takes place,
+often, but not always, at the expense of the sexual organs of the
+flower. Perhaps even more frequent is the increased number of parts in
+the same whorl in cases of regular peloria; thus, in the Pelargoniums
+before alluded to, the parts of the flower are frequently regulated by
+the number six instead of five.</p>
+
+<p>This form of peloria is most generally met with in flowers that are
+placed at the end or in the centre of the inflorescence, or in such
+flowers as occur singly at the end of the flower-stalk, as in
+<i>Trop&aelig;olum</i>, <i>Viola</i>, &amp;c. It would hence seem as if the freedom from
+pressure or restriction on one side allowed the flower to develop
+equally in all directions, and thus to produce regularity of form.</p>
+
+<p>It is obvious, from what has been before said, that the process of
+fertilisation is in many cases interfered with and altered by the change
+in the conformation or the flower.</p>
+
+<p>From overlooking the occasional existence of this form of peloria, new
+genera have sometimes been formed on insufficient grounds. The genus
+<i>Aceranthus</i>,<span class='pagenum'><a name="Page_226" id="Page_226">[Pg 226]</a></span> for instance, consists of species of <i>Epimedium</i> in which
+the customary spurs are not formed.<a name="FNanchor_229_229" id="FNanchor_229_229"></a><a href="#Footnote_229_229" class="fnanchor">[229]</a></p>
+
+<p>The occurrence both of regular and irregular peloria on the same plant
+has frequently been observed in <i>Linaria</i>. It has also been remarked
+that the seedlings raised from these forms are not always constant;
+thus, the late Mr. Crocker, formerly foreman in the Royal Gardens, Kew,
+informed me that he fertilised some flowers of a drooping Gloxinia with
+their own pollen, and that when the seedlings blossomed a large number
+of them produced the erect regular flowers.</p>
+
+<p>From what has been already said it will be seen that regular peloria is
+closely allied to what Morren called epanody, or a return to the normal
+condition. The reversion of a monstrous form to the normal one, as, for
+instance, when the fern-leaved beech reverts to the normal type, was
+called by the same author epistrophy.<a name="FNanchor_230_230" id="FNanchor_230_230"></a><a href="#Footnote_230_230" class="fnanchor">[230]</a></p>
+
+<p>The following are the genera in which regular peloria has been most
+often observed. It must, however, be remarked that in some of the
+flowers recorded as peloric there is no indication as to which form of
+peloria the case should be referred to. For other illustrations refer to
+chapters on Heterogamy, Number, Irregular Peloria, &amp;c.</p>

+
+<p>Most irregular flowers owe their irregularity to an unequal development
+of some of their organs as compared with that of others. When such
+flowers become exceptionally regular they do so either because
+development does not keep pace with growth, and a regular flower is thus
+the result of an arrest of the former process (regular peloria), or
+because the comparatively excessive development, which usually occurs in
+a few parts is, in exceptional cases manifested by all, hence the flower
+becomes regular from the increase in number of its irregular elements.
+These latter cases, then, are due to an excess of development, hence the
+application of the term pleiomorphy. It must be understood that mere
+increase in the number of the organs of a flower is not included under
+this head, but under that of deviations from the ordinary number of
+parts.</p>

+IRREGULAR PELORIA.</h4>
+
+
+<p>The term peloria was originally given by Linn&eacute; to a malformation of
+<i>Linaria vulgaris</i>, with five spurs and five stamens, which was first
+found in 1742 near Upsal. This was considered so marvellous a
+circumstance that the term peloria, from the Greek <span class="greek" title="[Greek: pel&ocirc;r]">&#960;&#949;&#955;&#969;&#961;</span>, a<span class='pagenum'><a name="Page_229" id="Page_229">[Pg 229]</a></span>
+prodigy, was applied to it.<a name="FNanchor_232_232" id="FNanchor_232_232"></a><a href="#Footnote_232_232" class="fnanchor">[232]</a> After a time other irregular flowers
+were found in like condition, and so the term peloria became applied to
+all cases wherein, on a plant habitually producing irregular flowers,
+regular ones were formed. The fact that this regularity might arise from
+two totally different causes was overlooked, or at least not fully
+recognised, even by Moquin-Tandon himself. Where a flower retains
+throughout life the same relative size in its parts that it had when
+those parts first originated the result is, of course, a regular flower,
+as happens in violets and other plants. This kind of peloria may for
+distinction sake be called regular or congenital peloria (see chapter on
+that subject); but where a flower becomes regular by the increase in
+number of its irregular portions, as in the <i>Linaria</i> already alluded
+to, where not only one petal is spurred, but all five of them are
+furnished with such appendages, and which are the result of an irregular
+development of those organs, the peloria is evidently not congenital,
+but occurs at a more or less advanced stage of development. To this
+latter form of peloria it is proposed to give the distinctive epithet of
+irregular.</p>
+
+<p>Peloria is either complete or incomplete; it is complete when the flower
+appears perfectly symmetrical, it is incomplete when only a portion of
+the flower is thus rendered regular. It is very common, for instance, to
+find violets or Linarias with two or three spurs, and these intermediate
+stages are very interesting, as they<span class='pagenum'><a name="Page_230" id="Page_230">[Pg 230]</a></span> serve to show in what way the
+irregularity is brought about. In <i>Antirrhinum</i>, <i>Linaria</i>, &amp;c.,
+intermediate forms show very clearly that it is to the repetition of the
+form usually assumed by the petals of the lower lip that the condition
+is due. This is also obvious in peloric flowers of the <i>Calceolaria</i>.
+The perfect peloria of this flower is in general erect, with five
+regular sepals, a regular corolla contracted at the base and at the
+apex, but distended in the centre so as to resemble a lady's sleeve,
+tight at the shoulder and wrist, and puffed in the centre!</p>

+
+<p>Morren<a name="FNanchor_233_233" id="FNanchor_233_233"></a><a href="#Footnote_233_233" class="fnanchor">[233]</a> describes a form intermediate between the ordinary
+slipper-shaped corolla and the perfect peloria just described, and which
+he calls sigmoid peloria. This flower is intermediate in direction
+between the erect peloria and the ordinary reflected flower. The tube is
+curved like a swan's neck and is dilated in front into two hollow
+bosses, such as we see in the lower lip of an ordinary flower; beyond
+these it is contracted and is prolonged into a slender beak terminating
+in two hollow teeth, between which is the<span class='pagenum'><a name="Page_231" id="Page_231">[Pg 231]</a></span> narrow orifice of the
+corolla. The colour at the base of the tube inside is as in the perfect
+peloria; while round the summit of the tube, in both cases, the
+intensity of colour is greatest on the outside. Now, in a normal flower
+the deepest colour is within just opposite the orifice of the corolla;
+this deep colour is also seen outside of the central and most elevated
+portions of the lower lip. In the peloria the deep colour at the base of
+the tube represents that which is near the orifice under ordinary
+circumstances, while the outer patch of colour at the apex corresponds
+to that formed on the upper surface of the lower lip. On the other hand,
+in peloric flowers of <i>Cytisus Laburnum</i>, <i>Clitoria Ternatea</i>,
+<i>Trifolium repens</i>, and other Papilionace&aelig;, it is the "standard," the
+form of which is repeated. In the case of peloric aconites<a name="FNanchor_234_234" id="FNanchor_234_234"></a><a href="#Footnote_234_234" class="fnanchor">[234]</a> the
+lateral and sometimes the inferior coloured sepals assume the hooded
+form usually peculiar to the upper sepal only, the number of the petals
+or nectaries being correspondingly increased. Balsams become peloric by
+the augmentation in the number of spurs.<a name="FNanchor_235_235" id="FNanchor_235_235"></a><a href="#Footnote_235_235" class="fnanchor">[235]</a> So when orchids are
+affected with irregular peloria it is the form of the labellum that is
+repeated, the accessory lips being sometimes the representatives of
+stamens, which are usually suppressed in these flowers,<a name="FNanchor_236_236" id="FNanchor_236_236"></a><a href="#Footnote_236_236" class="fnanchor">[236]</a> but at
+other times the appearance is due simply to the fact that all three
+petals assume the form usually confined to the lip, the staminal column
+being unaffected, except that its direction and relative position with
+reference to the other parts of the flower is different from ordinary.
+This was the case in some flowers of <i>Phal&aelig;nopsis equestris</i> sent to me
+by Mr. Wentworth Buller. Fig. 123 represents a flower of <i>Aristolochia
+caudata</i> with two lips, for which I am indebted to Mr. W. H. Baxter.</p>
+
+<p>From these cases it is evident that the flowers in<span class='pagenum'><a name="Page_232" id="Page_232">[Pg 232]</a></span> question become
+regular by the repetition of the irregular parts.</p>

+
+<p>It is probable that peloria may occur in any habitually irregular
+flower, and that, if more attention were directed to the subject,
+illustrations might be obtained from a larger number of natural families
+than can be done at present. It is, however, necessary to exercise
+discrimination, and not to attribute to peloria all the cases that at
+first sight appear to be so referable. Thus, Professor Dickson exhibited
+at the Botanical Society of Edinburgh, December 13th, 1860, four
+abnormal flowers of the common Indian cress (<i>Trop&aelig;olum majus</i>), each
+presenting a supernumerary spur. On these he remarked that "in
+<i>Trop&aelig;olum</i> the posterior<span class='pagenum'><a name="Page_233" id="Page_233">[Pg 233]</a></span> part of the receptacle between the insertion
+of the petals and that of the stamens is dilated so as to form the spur
+which is so characteristic in the genus. The position of the spur in a
+line with the posterior sepal has led many botanists to consider it as a
+process of that sepal, but the fact of its being situated within the
+insertion of the petals is conclusive as to its receptacular origin. In
+the flowers exhibited the supernumerary spur (as if to show its want of
+connection with any sepal) was placed exactly between a lateral sepal
+and one of the anterior sepals, sometimes on the one side of the flower
+and sometimes on the other. These additional spurs were precisely
+similar to the normal ones, except that they were a little shorter. This
+abnormality, although at first sight seeming to indicate a pelorian
+tendency, is no approximation to regularity, from the fact of the extra
+spur being differently placed, with regard to the sepals, from the
+normal one."</p>
+
+<p>Peloria of this kind, when perfect, is very often associated with other
+alterations. Change of direction is one of the most common of these; the
+usually drooping flower becomes erect, the stamens and style also are
+changed in direction, while, not unfrequently, either the one or the
+other (most often the stamens) are entirely suppressed. With this
+suppression an increase in the size of the flower very generally
+coincides. The number of parts is also frequently increased; thus, in
+<i>Antirrhinum majus</i> the corolla, when subjected to peloria, is very
+generally six-parted, and has six stamens. Fusion of one or more flowers
+is also a common accompaniment of peloria, as in <i>Digitalis purpurea</i>,
+in which plant prolification often adds increased complexity to the
+flower.</p>
+
+<p>It has been stated by Moquin and others that the uppermost flower of an
+inflorescence is the most subject to peloria; the uppermost flower of
+<i>Teucrium campanulatum</i>, for instance, is very generally regular. In
+<i>Calceolaria</i> it is the central terminal flower which is usually
+peloriated; on the other hand, in <i>Linaria</i> and <i>Antirrhinum</i><span class='pagenum'><a name="Page_234" id="Page_234">[Pg 234]</a></span> the lower
+flowers, or those on the secondary branches, are quite as often affected
+as the primary ones. Cassini considered that the spur of <i>Linaria</i> was
+developed from the lower petal rather than from the upper ones, because
+there is more room on the side of the flower farthest from the stem than
+on the opposite side. With reference to this point, M. Godron remarks
+that in habitually irregular flowers the apex of the peduncle is
+oblique, and hence the flowers are bent downwards or spread
+horizontally, but if the receptacle be quite flat and level then the
+flower is regular. The oblique position causes some of the organs to
+press on others, and hence induces abortion and suppression of some
+parts and increased growth in others that are not subjected to pressure.
+In a terminal peloriated flower of aconite, described by this
+naturalist, the flower was removed so far from the nearest bracts that
+all its parts had the chance of growing regularly. In ordinary cases M.
+Godron considers that the compression of the lateral bracts is the cause
+of the irregularity of the andr&oelig;cium and of the receptacle.<a name="FNanchor_237_237" id="FNanchor_237_237"></a><a href="#Footnote_237_237" class="fnanchor">[237]</a></p>
+
+<p>It has also been somewhat too generally stated that peloria occurs
+principally on luxuriant vigorous plants. It seems quite as often to
+happen in plants characterised by their deficiencies in this respect. On
+this point M. de Melicoq<a name="FNanchor_238_238" id="FNanchor_238_238"></a><a href="#Footnote_238_238" class="fnanchor">[238]</a> says, referring to <i>Linaria vulgaris</i>
+affected with peloria, that on the weakest plants the peloriated flower
+was at the top of the stem; while in stronger plants, with more numerous
+flowers and larger foliage, the peloriated flowers were principally to
+be found in the centre and at the base of the inflorescence, and their
+pedicels were much longer than usual.</p>
+
+<p>Linn&eacute;, as has been already stated, considered these flowers to be
+sterile, and only capable of multiplication by division of the root, but
+Willdenow obtained<span class='pagenum'><a name="Page_235" id="Page_235">[Pg 235]</a></span> seeds from the <i>Linaria</i> which reproduced the
+anomaly when sown in rich soil. Baron Melicoq obtained similar
+results.<a name="FNanchor_239_239" id="FNanchor_239_239"></a><a href="#Footnote_239_239" class="fnanchor">[239]</a> Mr. Darwin<a name="FNanchor_240_240" id="FNanchor_240_240"></a><a href="#Footnote_240_240" class="fnanchor">[240]</a> raised sixteen seedling plants of a
+peloric <i>Antirrhinum</i>, artificially fertilised by its own pollen, all of
+which were as perfectly peloric as the parent plant. On the other hand,
+the same observer alludes to the tendency that these peloric plants have
+to revert to the usual form, as shown by the fact that when the peloric
+flowers were crossed with pollen from flowers of the ordinary shape, and
+<i>vice vers&acirc;</i>, not one of the seedlings, in either case, bore peloric
+flowers. Hence, says Mr. Darwin, there is in these flowers "a strong
+latent tendency to become peloric, and there is also a still greater
+tendency in all peloric plants to reacquire their normal irregular
+structure." So that there are two opposed latent tendencies in the same
+plant. A similar remark has been made with reference to malformations in
+general by other observers.</p>
+
+<p>It would be very interesting if some competent naturalist would collect
+information as to whether any variations in degree of fertility exist in
+the three forms of flowers in <i>Linaria</i>, viz. the ordinary one-spurred
+form, which is intermediate between the spur-less and the five-spurred
+form. It must be remembered, however, that in the latter cases the
+stamens are often deficient. In the <i>Composit&aelig;</i>, where there are regular
+flowers in the disc and irregular ones in the ray, sexual differences,
+as is well known, accompany the diversities in form.</p>
+
+<p>To Mr. Darwin the author is indebted for the communication of some
+flowers of <i>Corydalis tuberosa</i> (figs. 124, 125), provided with two
+spurs of nearly equal size. To these flowers allusion is made in the
+work already quoted<a name="FNanchor_241_241" id="FNanchor_241_241"></a><a href="#Footnote_241_241" class="fnanchor">[241]</a> in the following terms:&mdash;"<i>Corydalis tuberosa</i>
+properly has one of its two nectaries colourless, destitute of nectar,
+only half the size of the other, and<span class='pagenum'><a name="Page_236" id="Page_236">[Pg 236]</a></span> therefore to a certain extent in a
+rudimentary state; the pistil is curved towards the perfect nectary, and
+the hood formed of the inner petals slips off the pistil and stamens in
+one direction alone, so that when a bee sucks the perfect nectary the
+stigma and stamens are exposed and rubbed against the insect's body. In
+several closely allied genera, as in <i>Dielytra</i>, there are two perfect
+nectaries; the pistil is straight, and the hood slips off on either
+side, according as the bee sucks either nectary." In the flowers of
+<i>Corydalis</i>, which were provided with two perfect nectaries containing
+nectar, Mr. Darwin considers that there has been a redevelopment of a
+partially aborted organ, accompanied by a change in the direction of the
+pistil, which becomes straight, while the hood formed by the petals
+slips off in either direction, "so that these flowers have acquired the
+perfect structure, so well adapted for insect agency, of <i>Dielytra</i> and
+its allies."</p>

+
+<p>Peloria, then, is especially interesting physiologically as well as
+morphologically; it is also of value in a systematic point of view, as
+showing how closely the<span class='pagenum'><a name="Page_237" id="Page_237">[Pg 237]</a></span> deviations from the ordinary form of one plant
+represent the ordinary condition of another; thus, the peloric
+Calceolarias resemble the flowers of <i>Fabiana</i>, and De Candolle,<a name="FNanchor_242_242" id="FNanchor_242_242"></a><a href="#Footnote_242_242" class="fnanchor">[242]</a>
+comparing the peloric flowers of <i>Scrophulariace&aelig;</i> with those of
+<i>Solanace&aelig;</i>, concluded that the former natural order was only an
+habitual alteration from the type of the latter. Peloric flowers of
+<i>Papilionace&aelig;</i> in this way are indistinguishable from those of
+<i>Rosace&aelig;</i>. In like manner we may trace an analogy between the normal
+one-spurred <i>Delphinium</i> and the five-spurred columbine (<i>Aquilegia</i>),
+an analogy strengthened by such a case as that of the five-spurred
+flower of <i>Delphinium elatum</i> described by Godron.<a name="FNanchor_243_243" id="FNanchor_243_243"></a><a href="#Footnote_243_243" class="fnanchor">[243]</a> The <i>Corydalis</i>,
+before referred to, is another illustration of the same fact, the
+structure being the same as in <i>Dielytra</i>, &amp;c.</p>
+
+<p>The ordinary irregular flowers may possibly be degenerated descendants
+of a more completely organized ancestor, and some of the cases of
+peloria may therefore be instances of reversion; some ancient <i>Linaria</i>
+may, perhaps, have had all its petals spur-shaped, and the cases of
+irregular peloria now found may be reversions to that original form.
+When both regular and irregular forms of peloria occur on the same
+plant, as they frequently do in <i>Linaria</i>, the one may be perhaps
+considered as a reversion to a very early condition, the other to a
+later state, when all the petals were irregularly formed. But before we
+can assert the truth of this surmise we must have better evidence as to
+what the original condition really was than we have at present.</p>
+
+<p>The proximate cause of irregular peloria has been considered to be
+excess of nourishment, but evidence as to this point is very
+conflicting. Willdenow states that "radices pelori&aelig;, solo sterili
+plantat&aelig;, degenerant in Linariam," ('Sp. Plant.,' iii, p. 254); but this
+opinion is counterbalanced by that of others, while the frequent<span class='pagenum'><a name="Page_238" id="Page_238">[Pg 238]</a></span>
+existence of both forms on the same plant, at the same time, seems to
+negative the supposition of any direct effect from external
+circumstances.</p>

+
+METAMORPHY.</h3>
+
+
+<p>Much of the objection with which Goethe's famous essay on the
+'Metamorphosis of Plants' was met on its publication may be traced to a
+misapprehension of the sense in which Goethe employed the word. As used
+by him, it had nearly the same signification as now applied to the word
+development by organogenists. It does not necessarily imply that there
+has been a change in any particular organ, but rather that there has
+been, to some extent, a change in the plan of construction, in
+accordance with which a deviation from the customary form results. The
+particular organ was never anything else than what it is; it has not
+been metamorphosed in the ordinary sense of the word; for instance, in a
+double flower, where the stamens are, as it is said, changed or
+metamorphosed into petals, no absolute change really has taken
+place&mdash;the petal was never a stamen, although it occupies the position
+of the latter, and may be considered a substitute for it.</p>
+
+<p>The term metamorphosis, then, really implies an alteration in the
+organizing force, taking effect at a very early period of the life of
+the flower, at or before the period when the primitive aggregation of
+cells, of which it is at that time composed, becomes separated or
+"differentiated" into the several parts of the flower. In other words,
+the "development" of the flower pursues a different course from what is
+usual. In the preceding sections the effects of arrest and of excess in
+this process have been partly treated of; other deviations arising from
+similar causes will be mentioned<span class='pagenum'><a name="Page_241" id="Page_241">[Pg 241]</a></span> elsewhere, but, under the present
+heading, are specially included cases not of merely diminished or
+increased, but of perverted development; the natural process is here not
+necessarily checked or enhanced, but it is changed. Hence, in the
+present work, the term metamorphy is employed to distinguish cases where
+the ordinary course of development has been perverted or changed. As it
+is applied solely for teratological purposes, the ordinary acceptation
+of the term, as nearly synonymous with "development," is not interfered
+with.</p>
+
+<p>In order to avoid other possible misapprehensions, the terms retrograde
+and progressive metamorphosis employed by Goethe are not herein used,
+their place being, to a great extent, supplied by the more intelligible
+expressions arrest or excess of development.<a name="FNanchor_244_244" id="FNanchor_244_244"></a><a href="#Footnote_244_244" class="fnanchor">[244]</a></p>

+PHYLLODY.</h4>
+
+
+<p>This condition, wherein true leaves are substituted for some other
+organs,<a name="FNanchor_245_245" id="FNanchor_245_245"></a><a href="#Footnote_245_245" class="fnanchor">[245]</a> must be distinguished from Virescence, q. v., in which the
+parts affected have simply the green colour of leaves, without their
+form or structure. The appearance of perfect leaves, in<span class='pagenum'><a name="Page_242" id="Page_242">[Pg 242]</a></span> place of other
+organs, is frequently looked on as due to retrograde metamorphosis, or
+to an arrest of development. But this is not strictly correct; for
+instance, suppose a petal, which is very generally merely the sheath of
+a leaf, with the addition of colouring matter, to be replaced by a
+perfect leaf, one in which all three constituent parts, sheath, stalk,
+and blade, are present, it surely can hardly be said that there has been
+any retrogression or arrest of development in the formation of a
+complete in place of an incomplete organ. The term retrograde here is
+used in a purely theoretical sense, and cannot be held to imply any
+actual degradation. Morphologically, as has been stated, the case is one
+of advance rather than the reverse, and hence the assignment of
+instances of this nature to a perversion of development, rather than to
+a diminution or to an exaltation of that process, seems most consistent
+with truth. The affected organs have really undergone no actual change,
+simply the direction of the organising force has been altered at a very
+early state, so that the usual differentiation of parts has not taken
+place.</p>

+<p><b>Phyllody of the bracts.</b>&mdash;As bracts are very generally imperfect organs,
+so their replacement by perfect leaves<span class='pagenum'><a name="Page_243" id="Page_243">[Pg 243]</a></span> is not attributable to arrest of
+development or retrograde metamorphosis, but the reverse. The bracts of
+some species of <i>Plantago</i><a name="FNanchor_246_246" id="FNanchor_246_246"></a><a href="#Footnote_246_246" class="fnanchor">[246]</a> are very subject to this change. Thus,
+in the rose plantain of gardens, <i>P. media</i> (fig. 126), the bracts are
+leafy and the axis depressed or not elongated, so that it is surmounted
+by a rosette of small leafy organs. A similar condition of the bracts,
+unattended with arrest of growth in the axis, is common in <i>P. major</i>
+(fig. 127) and in <i>P. lanceolata</i> (<a href="#Page_108">see p. 108</a>). It also occurs in the
+bracts of <i>Corydalis solida</i>, <i>Amorpha fruticosa</i>, <i>Ajuga reptans</i>,
+<i>Parthenium inodorum</i>, <i>Centaurea Jacea</i>, in the involucral bracts of
+the dandelion, the<span class='pagenum'><a name="Page_244" id="Page_244">[Pg 244]</a></span> daisy, and many other composites. In the 'Gardeners
+Chronicle,' 1852, p. 579, is figured a dahlia in which the bracts of the
+involucre and the scales of the receptacle had all assumed the form,
+texture, and venation of leaves.<a name="FNanchor_247_247" id="FNanchor_247_247"></a><a href="#Footnote_247_247" class="fnanchor">[247]</a></p>

+
+
+<p><b>Phyllody in inflorescence of Conifers.</b>&mdash;This demands passing notice by
+reason of the interest attaching to the morphological construction of
+these plants. The elongation of the axis which occurs in the female
+cones has been already alluded to under the head of prolification of the
+inflorescence. This change is frequently associated with a more or less
+foliaceous condition of the bracts, which, indeed, may be seen to be
+serially continuous, both above and below, with the ordinary leaves. The
+scales, too, become notched and bipartite, and show, between the lobes,
+the rudiment of a bud, which in a further stage becomes developed into a
+shoot bearing leaves. Such a change has been described by Parlatore in
+<i>Abies Brunoniana</i>, and examples may frequently be met with in the larch
+(<i>Larix europ&aelig;a</i>), and specially in <i>Cryptomeria japonica</i>.<a name="FNanchor_253_253" id="FNanchor_253_253"></a><a href="#Footnote_253_253" class="fnanchor">[253]</a> The
+scales of the male catkins of conifers likewise occasionally assume the
+appearance of leaves; this may be seen in monstrous catkins of
+<i>Araucaria</i>, as also in <i>Podocarpe&aelig;</i> and <i>Cupressine&aelig;</i> (Eichler).</p>
+
+
+
+<p><b>Phyllody of the calyx.</b>&mdash;Sepals under ordinary circumstances are so like
+leaves, that it is not wonderful that<span class='pagenum'><a name="Page_246" id="Page_246">[Pg 246]</a></span> they are often replaced by those
+organs.<a name="FNanchor_254_254" id="FNanchor_254_254"></a><a href="#Footnote_254_254" class="fnanchor">[254]</a> A singular instance of this has been mentioned as occurring
+in <i>Cakile maritima</i>, wherein the sepals were found by M. Fournier to be
+pinnatifid like the ordinary leaves of the plant.<a name="FNanchor_255_255" id="FNanchor_255_255"></a><a href="#Footnote_255_255" class="fnanchor">[255]</a> The sepals of
+<i>Ranunculace&aelig;</i> and <i>Rosace&aelig;</i>, for example, <i>Rosa</i>, <i>Geum</i>, are
+particularly liable to this change.</p>

+
+<p>In a species of <i>Geranium</i> recently examined the sepals presented
+themselves in the form of three-lobed leaflets; so in fuchsias and in
+<i>Epilobium hirsutum</i> the sepals occasionally are not distinguishable
+from ordinary leaves (fig. 130). In roses, the change in question is a
+very frequent accompaniment of prolification (fig. 129). In the peach
+also this replacement of the sepals is<span class='pagenum'><a name="Page_247" id="Page_247">[Pg 247]</a></span> sometimes carried to such an
+extent, that five perfect, bistipulate leaves occur in the place of the
+calyx, but when this is the case it usually happens that the pistil is
+abortive.</p>

+<p>De Candolle<a name="FNanchor_256_256" id="FNanchor_256_256"></a><a href="#Footnote_256_256" class="fnanchor">[256]</a> figures a curious instance wherein the pappus of
+<i>Podospermum laciniatum</i> was replaced by five linear, foliaceous lobes.
+A similar change has been noticed in other composites, as in <i>Tragopogon
+pratense</i>. Engelmann mentions as subject to this hypertrophy of the
+pappus, as it may be termed, <i>Scorzonera octangularis</i> and <i>Senecio
+vulgaris</i>. Wigand has observed a similar transformation in a species of
+<i>Centranthus</i> (<i>Valerianace&aelig;</i>).</p>
+
+<p>In some cases the phyllody of the sepals has a special interest, as
+bearing on the question whether what is termed calyx-tube is or is not a
+portion of the calyx, and whether the sepals are modifications of the
+blade or of the sheath of the leaf. Thus in the primrose the phyllodic
+sepals seem to show clearly that the sepals are in that plant of a
+laminar nature (fig. 131). The so-called calyx-tube of roses is
+elsewhere alluded to. The leaf-like organs sometimes seen at the apex of
+a cucumber would seem to support the view that there was really a
+calyx-tube in <i>Cucurbitace&aelig;</i> adherent to the carpels. It is also shown
+in the cut,<span class='pagenum'><a name="Page_248" id="Page_248">[Pg 248]</a></span> fig. 132, borrowed from the 'Gardeners' Chronicle,' 1859,

+
+<p>Under ordinary circumstances, the sepals may be considered as the
+representatives of the sheath of the leaf (cataphyllary) or of the blade
+(euphyllary), the arrangement of the veins being different in the two
+cases; thus, in the vagina or sheath, there are generally several large
+veins of about equal size, either convergent towards the apex, or
+divergent; on the other hand, in the blade, there is usually but one
+central vein, the midrib, larger than the rest, and the smaller veins
+come off at a less acute angle, and are more reticulated.<a name="FNanchor_257_257" id="FNanchor_257_257"></a><a href="#Footnote_257_257" class="fnanchor">[257]</a></p>
+
+<p>Now, when phyllomorphy occurs in sepals which ordinarily are vaginal, it
+is obvious that the case is one, not merely of increased relative
+growth, but also of the appearance or development of an organ habitually
+suppressed; on the other hand, when phyllomorphy occurs in sepals which
+usually are laminar in form and nervation, the case is one of unusual
+growth or hypertrophy, and not of the development of an organ habitually
+suppressed, so that the amount of change is greater in the former than
+in the latter instance.</p>
+
+<p>Under normal circumstances it will be found that laminar venation is
+most common in gamosepalous and vaginal venation in polysepalous
+calyces. And the same holds good in cases where the calyx is abnormally
+leafy. The complete leaf development shows itself more frequently among
+the monosepalous<span class='pagenum'><a name="Page_250" id="Page_250">[Pg 250]</a></span> plants than in the polysepalous ones, as shown even in
+the subjoined list of species. This statement would be more fully
+verified were it possible to state the frequency with which the
+condition occurred in <i>individual plants</i>, when it would be found that
+phyllody of the calyx occurs much more often in individual gamosepalous
+plants than in polysepalous ones.</p>

+
+<p>The frondescent petals are very often completely disjoined, as in
+<i>Verbascum nigrum</i>, and <i>Lonicera Periclymenum</i>, in which, moreover,
+median prolification generally coexists. In the case of <i>Trop&aelig;olum
+majus</i>, the ordinary leaves of which are peltate and orbicular, the
+petals when frondescent have not the peltate arrangement, but are
+spathulate, and provided with very long, narrow stalks, so that, in some
+cases, they are, more properly speaking, enlarged virescent petals than
+true leaves; in other instances, however, the arrangement of the veins
+is more like that of the true leaves than that of the petals.</p>
+
+<p>As might be expected, frondescence of the petals is frequently
+accompanied by other changes of a similar nature in other parts of the
+flower, and sometimes by the abortion of the sexual organs. Thus, in
+<i>Act&aelig;a spicata</i>, as observed by Fresenius, the petals were replaced by
+true petiolate, palminerved, lobed leaves,<span class='pagenum'><a name="Page_252" id="Page_252">[Pg 252]</a></span> the stamens and pistils
+being abortive. In <i>Ranunculus</i> the leaves that appear in the place of
+the petals have no scale at their base, and in <i>Trop&aelig;olum</i> the calyx (or
+receptacle) is free from the usual spur.</p>
+
+<p>The absolute frequency of this occurrence seems to be greatest in those
+flowers which are normally polypetalous. The petals of these flowers, as
+a general rule, are more like the leaf-sheaths than the leaf-blades as
+to their venation, hence it would seem that the phyllomorphic condition
+in these petals is a manifestation of a greater degree of organizing
+force than that which occurs in those cases where the petals are
+normally present in the form of contracted blades or lamin&aelig;. (See the
+remarks in the preceding section.)</p>

+<p><b>Phyllody of the stamens</b> happens less frequently than the corresponding
+condition in the neighbouring organs. The structure of the anther is so
+much removed from that of the leaf, that the change of the stamen from
+its ordinary condition to that of a leaf must be regarded as indicating
+a greater degree of perverted development than that which occurs in
+those cases where less highly differentiated organs, such as the sepals,
+petals, and pistils, are thus altered.<a name="FNanchor_260_260" id="FNanchor_260_260"></a><a href="#Footnote_260_260" class="fnanchor">[260]</a></p>
+
+<p>In all cases it is desirable to ascertain, if possible, what parts of
+the stamen are thus transformed. In some Petunias the filaments are
+unchanged, but in place of the anther is a small lamina, representing
+precisely the blade of an ordinary leaf. Sometimes the connective only
+is replaced by a leaf. One of the most interesting cases of this kind
+that has fallen under the writer's observation was in <i>Euphorbia
+geniculata</i>, in which, in addition to other changes mentioned under
+prolification of the inflorescence, some of the stamens were partly
+frondescent,<span class='pagenum'><a name="Page_254" id="Page_254">[Pg 254]</a></span> half the anther being perfect, the other half leaf-like.
+Another filament bore just above the usual joint three leaflets, two
+lateral ones, somewhat conduplicate, and a third central one, half
+anther, half leaflet.</p>

+
+
+<p>In the case of frondescent flowers of <i>Trop&aelig;olum majus</i> the stamens are
+usually absent or atrophied, but in other instances the filament is
+present as usual, representing the stalk of the leaf, and surmounted by
+a small lamina, but this latter, in place of being nearly flat, is
+pinched up in the centre from back to front, and surmounted by a
+two-lobed anther, so that the general appearance of the whole structure
+is that of a central anther, supported at the base on each side by two
+concave leaf-lobes, or it might be compared with a three-lobed leaf, the
+terminal lobe represented by the anther.</p>
+
+<p>In <i>Jatropha Pohliana</i>, M&uuml;ll. (<i>Adenorophium luxurians</i>, Pohl.), a
+singular condition has been observed by M. M&uuml;ller (Argov.). In this
+flower the anther, in place<span class='pagenum'><a name="Page_255" id="Page_255">[Pg 255]</a></span> of being represented by the flat blade of a
+single leaf, had the appearance as if two such blades were present and
+coherent one with the other by their midribs, along their upper or inner
+surfaces, which were directed towards the centre of the flower (fig.
+136), thus resembling the cases of adhesion of leaves by their surfaces
+already referred to (p. 33). In other cases, in the same plant, the
+anther appeared as if formed by two collateral leaves, the faces looking
+towards the circumference of the flower, and their margins so folded
+together as to represent an open anther lobe (fig. 135). These cases are
+apparently due, not to the formation and adhesion of two leaves, but
+rather to the exuberant development of one leaf into two blades.<a name="FNanchor_261_261" id="FNanchor_261_261"></a><a href="#Footnote_261_261" class="fnanchor">[261]</a>

+the corresponding change in the case of the stamens. It is of interest,
+as it sometimes serves to illustrate the morphological nature of the
+pistil. Of this the double-flowering cherry is a well-known
+illustration, the pistil being here represented by two small foliar
+lamin&aelig;, whose midribs are prolonged with a short style, terminated by an
+imperfect stigma. It is usually the basal portion of the pistil, the
+ovary, which is thus specially affected, the margins being also often
+disunited so as to expose the ovules. These latter organs may be absent
+or they may themselves be the subjects of foliaceous development.
+Moquin<a name="FNanchor_263_263" id="FNanchor_263_263"></a><a href="#Footnote_263_263" class="fnanchor">[263]</a> relates having found in the neighbourhood of Montpellier a
+flower of a tulip the ovary of which was represented by true leaves,
+which bore on their margins the ovules, and thus presented a striking
+analogy with the carpels of those Sterculias, like <i>S. platanifolia</i>,
+which are foliaceous in texture and open very early in the course of
+their development. A similar occurrence<span class='pagenum'><a name="Page_257" id="Page_257">[Pg 257]</a></span> has also been frequently
+noticed in the Columbine and also in <i>Crucifer&aelig;</i> and <i>Umbellifer&aelig;</i>. M.
+Germain de St. Pierre mentions an instance wherein the carpels of <i>Salix
+Babylonica</i> were converted into two leaves, provided with stipules. All
+the flowers of the catkins<span class='pagenum'><a name="Page_258" id="Page_258">[Pg 258]</a></span> were similarly changed, so that it became

+
+<p>Fig. 138, for which I am indebted to Mr. S. J. Salter, represents a very
+singular conformation in the cucumber, described by that gentleman in
+'Henfrey's Botanical Gazette,' i, p. 208, and considered by him to be
+due to the foliaceous condition of one of the three carpels of which the
+fruit is composed. The portion near the peduncle was binary, while the
+distal extremity of the fruit was ternary. The main difficulties
+attending the acceptance of this explanation reside in the peculiar
+reversed position of the leaf, and in the fact that the fruit of the
+<i>Cucurbitace&aelig;</i> is probably of axial nature, the dilated and succulent
+end of the peduncle adhering to and usually concealing the carpels; in
+some cases, however, these latter project beyond the axial portion,
+leaving no doubt as to the true nature of the structure in these
+particular instances.</p>
+
+<p>Admitting the axial nature of the fruit, it might be supposed that in
+Mr. Salter's cucumber an adventitious leaf had been given off from the
+axis, but even on that supposition the reversed position offers a
+difficulty, and there still remains to be explained the fact that the
+proximal part of the fruit was binary in its constitution, the distal
+end ternary.</p>
+
+<p>M. Norman<a name="FNanchor_264_264" id="FNanchor_264_264"></a><a href="#Footnote_264_264" class="fnanchor">[264]</a> mentions a case wherein the carpels of <i>Anchusa
+ochroleuca</i> were replaced by two leaves; from this he draws the
+inference that the pistil of borages and labiates is really composed of
+two leaves, placed fore and aft, the margins of the leaves being
+congenitally fused. This tallies well with the account given of the
+development of these plants by Payer, Germain de St. Pierre, and others.</p>
+
+<p>In an Indian species of <i>Triumfetta</i>, not only were the petals
+virescent, but the ovary also was much enlarged, and in some flowers it
+was divided half way down into five lanceolate leaves (fig. 139), the
+sepals and stamens being in their normal condition.</p><p><span class='pagenum'><a name="Page_260" id="Page_260">[Pg 260]</a></span></p>
+
+<p>In the preceding instances the foliaceous condition has pervaded the
+entire pistil, or at any rate the basal portion or ovary, and it may be
+noticed that the ovary is thus shown to consist in some cases of the
+sheath of the leaf, as in <i>Aquilegia</i>; in other cases of the blade, as
+in <i>Cerasus</i>, <i>Daucus</i>, &amp;c.</p>

+
+<p>There are cases, however, in which a part only of the pistillary
+structure thus becomes foliaceous. Linn&aelig;us, 'Prolepsis,' &sect; 9, mentions
+some flowers of <i>Carduus heterophyllus</i> and <i>C. tataricus</i> in which the
+style had grown into two green leaflets, and in which the calyx and
+corolla were also leaf-like. A very singular instance is recorded by
+Baillon,<a name="FNanchor_265_265" id="FNanchor_265_265"></a><a href="#Footnote_265_265" class="fnanchor">[265]</a> wherein the pistil of <i>Trifolium repens</i> consisted of
+three carpels, either separate, or combined so as to form a one-celled
+ovary with three parietal, pluri-ovulate placent&aelig;; the ovary in these
+flowers was formed of the basal vaginiform part of the leaf; the three
+styles were formed by the petioles, while the stigmas were represented
+by trifoliolate leaves. The back of the leaf in these cases is usually
+directed away from the centre of the<span class='pagenum'><a name="Page_261" id="Page_261">[Pg 261]</a></span> flower. When this change occurs it
+is commonly attended by an increased number of parts, as in the trefoil
+just mentioned, or in the double cherry, where usually two foliaceous
+carpels may be met with, and sometimes more.</p>
+
+<p>The change is also of interest when it affects such orders as the
+<i>Umbellifer&aelig;</i>, which have their ovaries inferior under ordinary
+circumstances; but when these organs assume a leafy condition they
+become superior also, <i>i.e.</i> they are detached from the calyx.</p>
+
+<p>As regards the position of the ovules in these foliaceous pistils, they
+may be placed, as in <i>Aquilegia</i>, <i>Delphinium</i>, &amp;c., on the edges of the
+carpel or on the surface, as in some flowers of <i>Ranunculus repens</i> and
+<i>R. Ficaria</i>. A similar position of the ovules is recorded in the case
+of the vine (<i>Vitis</i>), where the pistil consisted of leaves bearing the
+ovules on their inner surface.<a name="FNanchor_266_266" id="FNanchor_266_266"></a><a href="#Footnote_266_266" class="fnanchor">[266]</a> The supposed causes of this and
+other similar malformations are alluded to under the head of chloranthy,
+but it may be here remarked that semi-double flowers, fertilised by the
+pollen of similar flowers, are said to produce flowers with a centre of
+small green leaves, this central tuft resulting from the expansion and
+frondescence of the pistils.</p>
+
+<p>As this condition rarely occurs without corresponding changes in other
+parts of the flower, further remarks on this subject will be found in

+
+<p><b>Phyllody of the ovules.</b>&mdash;Pending the settlement of the existing
+differences of opinion with reference to the morphological nature of the
+ovule and its component parts, much interest attaches to the
+malformations to which they are occasionally subject. Considered purely
+in a teratological point of view, it seems clear that the ovular coats
+are usually, if not always, of foliar nature, while the central nucleus
+is an axial organ; but if this be so there still remains the question
+whether the leafy coats of the ovule are processes of the carpel itself,
+or distinct independent formations, like the scales of a leaf-bud; as to
+this latter point, the evidence is at present very conflicting. Prof.
+Al. Braun, who has devoted much attention to the subject, describes and
+figures ovules of <i>Nigella</i> and <i>Adonis</i>, wherein the outer coat of the
+ovule was converted into a leafy, lobed mass, like the ordinary leaves,
+and these he considers to be a portion, not of the carpel, but of the
+ovular bud; he, however, hesitates to pronounce an opinion on the nature
+of the pedicel of the ovule. In <i>Primulace&aelig;</i>, wherein ovular changes are
+very common, the leafy coat of the ovule would seem, from the nature of
+the placenta, to be independent of the carpel. Morren, who studied the
+changes in the<span class='pagenum'><a name="Page_263" id="Page_263">[Pg 263]</a></span> ovules of <i>Primula sinensis</i>, applied the term
+lepyrophylly (<span class="greek" title="[Greek: lepyron]">&#955;&#949;&#960;&#965;&#961;&#959;&#957;</span>, a scale) to the foliaceous condition of
+the testa in this plant. Unger<a name="FNanchor_267_267" id="FNanchor_267_267"></a><a href="#Footnote_267_267" class="fnanchor">[267]</a> describes a series of malformations
+in <i>Primula sinensis</i>, consisting chiefly of reversions of the part of
+the flower to leaves. The carpels were entirely absent in this case, and

+<p>In these flowers the placenta seemed to be composed of several funiculi
+soldered together, and bearing imperfect ovules. In other cases no
+traces of ovules are visible, but the funiculi are in a foliaceous
+condition. Moquin also alludes to a case of the same nature in <i>Cortusa
+Mathioli</i>, in which the funiculi bore little rounded leaves. Brongniart
+has described some malformations of <i>Primula sinensis</i> in which the
+ovules were transformed wholly or partially into small leaves with three
+to five lobes.<a name="FNanchor_269_269" id="FNanchor_269_269"></a><a href="#Footnote_269_269" class="fnanchor">[269]</a> Dr. Marchand<a name="FNanchor_270_270" id="FNanchor_270_270"></a><a href="#Footnote_270_270" class="fnanchor">[270]</a> mentions similar changes in

+ovules were replaced by two small linear leaves arising entirely from
+the axis, and not from the carpels.</p>
+
+<p>In most of the foregoing illustrations the foliar portion of the ovule
+must have been independent of the carpel; this independence is less
+manifest, though probably as<span class='pagenum'><a name="Page_264" id="Page_264">[Pg 264]</a></span> real in the cases now to be mentioned. In
+<i>Sinapis</i> and in <i>Brassica oleracea</i> foliaceous ovules may occasionally

+to Griffith, is a leaf united along its margins, but always more or less

+funicle, with which its margins also cohere.</p>

+trace all the gradations between the simple<span class='pagenum'><a name="Page_266" id="Page_266">[Pg 266]</a></span> cup formed by the

+
+<p>One of the most singular instances of ovular malformation in record is
+that cited by the Rev. M. J. Berkeley, in the 'Gardener's Chronicle,'
+September 28th, 1850, p. 612. The plant was a carnation, and its
+placenta bore, not only ovules, but also carpels (fig. 146), the latter
+originating in a perverted development<span class='pagenum'><a name="Page_268" id="Page_268">[Pg 268]</a></span> of the former, so that many
+intermediate stages could be traced between the ordinary ovule and the
+ovary (fig. 147, 1, <i>a</i>, 2, <i>b</i>). Some of these carpels, thus derived
+from the ovules, themselves bore secondary ovules on a marginal
+placenta, as shown in the sections at <i>c</i>, <i>d</i>, <i>e</i>. Could such a change
+occur in the animal kingdom, there would be the unfertilised ovum<span class='pagenum'><a name="Page_269" id="Page_269">[Pg 269]</a></span>
+converted into an ovary, and this again bearing Graafian vesicles! In
+Mr. Berkeley's carnation the change was not so great, seeing that the
+nucleus of the ovule was not developed, and sufficient evidence has been
+above given as to the foliar nature of the primine, while for a leaf to
+be folded up so as to form a carpel is an ordinary occurrence.</p>
+
+<p>It is worthy of remark that in these foliaceous ovules there is never
+more than one coat, the secondine and other integuments do not make
+their appearance in these cases, and that very generally the change in
+question accompanies a similar foliaceous condition in the carpel, the
+margins of which are more or less disunited.</p>
+
+<p>Prof. A. Braun remarks that up to this date no such change has been
+observed in the ovules of Monocotyledons.</p>
+
+
+
+<p><b>Changes in the nucleus of the ovule.</b>&mdash;The preceding remarks have had
+reference especially to the ovular coats, but it is desirable also to
+allude to certain points connected with the nucleus. Very frequently,
+when the coat of the ovule is phylloid, as before described, the nucleus
+is altogether wanting, though sometimes it is present as a small
+cellular papilla; very rarely is it to be found in its perfect state.
+Occasionally the nucleus is present in the guise of a small elongated
+branch. Wigand cites ovular buds in every stage of progress into a
+branch, sometimes even bearing indications of anthers. Wydler has
+observed a similar occurrence in ovules of <i>Alliaria officinalis</i>, and
+Schimper has described and figured specimens of <i>Nigella damascena</i> in
+which the outer coats of the ovule were but little changed, while the
+nucleus was replaced by a leafy shoot. On one of the leaves of this
+latter was found an imperfect ovule&mdash;an ovule on an ovule!</p>
+
+<p>Fig. 148 shows a floret of a species of <i>Gaillardia</i>, in which the ovule
+was replaced by a leafy shoot which had made its way through a chink in
+the ovary. In<span class='pagenum'><a name="Page_270" id="Page_270">[Pg 270]</a></span> this specimen, however, there was no evidence to show
+whether the shoot in question was a perverted development of the
+nucleus, or whether it was wholly independent of the ovule.</p>
+
+<div class="center">

+  </a>
+<p class="caption"> <span class="smcap">Fig.</span> 148.&mdash;Floret of <i>Gaillardia</i>, showing leafy shoot occupying the place of the ovule.</p>
+</div>
+
+<p>From this occasional elongation of the nucleus, as well as from the
+foliar nature of the ovular coats, Prof. Alex. Braun arrives at the
+conclusion that the ovule is to be looked on as a bud, the ovular
+coatings, so often variable in number, representing the scales of the
+bud, the nucleus corresponding to the end of the axis or growing point.
+Griffith had previously expressed the same opinion from his observations
+on malformed ovules of <i>Sinapis</i> and <i>Lonicera</i>, while Caspary's
+conclusions from the foliaceous ovules of <i>Trifolum repens</i> are somewhat
+similar. The latter observer considers that the funiculus, with the
+integuments, is the equivalent of a leaflet, the petiolule or midrib of
+which answers to the funiculus, and its hollow expansion to the
+integument. The nucleus itself is considered to be a new formation
+analogous to a shoot.</p><p><span class='pagenum'><a name="Page_271" id="Page_271">[Pg 271]</a></span></p>
+
+<p>M. van Tieghem's conclusion<a name="FNanchor_278_278" id="FNanchor_278_278"></a><a href="#Footnote_278_278" class="fnanchor">[278]</a> from the examination, of flowers of
+<i>Trop&aelig;olum majus</i>, in which the ovules were replaced by perfect peltate
+leaves, is that the ovules are foliar productions springing, not
+directly from a prolonged floral axis, as in <i>Primulace&aelig;</i>, but from
+branches of the axis arising from the axils of the carpellary leaves.</p>

+<p><b>Phyllody in accessory organs.</b>&mdash;In addition to the ordinary organs of the
+plant, what are termed the accessory organs, such as hairs, spines, &amp;c.,
+sometimes become foliaceous. It is not to be wondered at that spines,
+when they represent the framework of a leaf, become sometimes clothed
+with cellular tissue, and thus become indeed true leaves. This happens
+occasionally in <i>Berberis;</i> a similar thing occurs in the stipules of
+some <i>Leguminos&aelig;</i>; the scales of some begonias; the tendrils of
+<i>Bignonia</i>, <i>Cob&aelig;a</i>, &amp;c.</p>
+
+<p>The presence of two small green lamin&aelig; on the outer side of the two

+<p><b>Chloranthy.</b>&mdash;The term phyllomorphy is applied to the individual parts of
+the flower which assume the form and appearance of leaves. By chloranthy
+it is to be understood that all, or the great majority of the organs of
+the flower assume these conditions.<a name="FNanchor_280_280" id="FNanchor_280_280"></a><a href="#Footnote_280_280" class="fnanchor">[280]</a> In chloranthy, as here defined,
+there is no unusual number of buds, as there is in prolification, but
+the appearance of the flower-bud is so changed as to make it resemble
+more closely a leaf-bud than a flower-bud. There is not necessarily any
+increase in the number, or any alteration in the position of the buds,
+but the form and appearance of the latter differ from what is usual.
+Chloranthy, then, is a more complete form of frondescence. Owing to the
+vagueness with which the word has been applied by various authors, it
+becomes very difficult to ascertain whether the recorded instances of
+chloranthy were really illustrations of what is here meant by that term,

+<p>Seringe<a name="FNanchor_281_281" id="FNanchor_281_281"></a><a href="#Footnote_281_281" class="fnanchor">[281]</a> has described a malformation in <i>Diplotaxis tenuifolia</i> in
+which all the floral organs were replaced by sixteen distinct leaflets
+which had preserved their proper relative position. The <i>Crucifer&aelig;</i>, of
+which family the last-named plant is a member, are particularly liable
+to this malformation, as also are the <i>Rosace&aelig;</i>, as will be seen from
+the following illustrations. Roses indeed often exhibit alterations of
+this kind as the commencement of prolification. There is also in
+cultivation a rose<a name="FNanchor_282_282" id="FNanchor_282_282"></a><a href="#Footnote_282_282" class="fnanchor">[282]</a> called the green rose, "Rose bengale &agrave; fleurs
+vertes," in which all the parts of the flower are represented by leaves.
+One of the most remarkable features in this plant is, that the carpels
+have often two ovules on their margins. Now, Payer, in his
+"Organog&eacute;nie," has shown that at a certain period of the development of
+the ordinary rose flower the ovary contains two collateral ovules, of
+which one<span class='pagenum'><a name="Page_275" id="Page_275">[Pg 275]</a></span> becomes in process of time suppressed.<a name="FNanchor_283_283" id="FNanchor_283_283"></a><a href="#Footnote_283_283" class="fnanchor">[283]</a> <i>Geum coccineum</i>
+has been found by Wigand with its flowers in this condition.<a name="FNanchor_284_284" id="FNanchor_284_284"></a><a href="#Footnote_284_284" class="fnanchor">[284]</a></p>
+
+<p>Lindley<a name="FNanchor_285_285" id="FNanchor_285_285"></a><a href="#Footnote_285_285" class="fnanchor">[285]</a> figures a very interesting illustration in <i>Potentilla
+nepalensis</i>, in which some of the flowers have their component parts
+leafy, in others the receptacle lengthens, till in extreme cases the
+whole of the floral apparatus is represented by a branch bearing a
+rosette of leaves.</p>
+
+<p>A particular variety of the Alpine strawberry is also described as
+occasionally subject to this transformation. In these flowers the calyx
+remains normal, while all the other parts of the flower, even to the
+coating of the ovule, assume a leaf-like condition.<a name="FNanchor_286_286" id="FNanchor_286_286"></a><a href="#Footnote_286_286" class="fnanchor">[286]</a> </p><p><span class='pagenum'><a name="Page_276" id="Page_276">[Pg 276]</a></span></p>
+
+<p>Among <i>Leguminos&aelig;</i> a partial leafy condition (frondescence), or a more
+complete degree of the same change, (chloranthy) is not infrequent,
+particularly in <i>Trifolium repens</i>. In this species the changes are so
+common, so various and important, that they may be alluded to in some
+little detail. M. Germain de Saint Pierre,<a name="FNanchor_287_287" id="FNanchor_287_287"></a><a href="#Footnote_287_287" class="fnanchor">[287]</a> in commenting on the
+frequency with which the flowers of this plant are more or less
+frondescent, remarks that although all the flowers on one plant may be
+affected, they are all changed in the same manner, but on different
+specimens different degrees of transformation are found. In all the
+corolla and stamens are comparatively little removed from the ordinary
+form, the calyx and pistil, however, have a particular tendency to
+assume a foliar condition. The author just cited arranges the
+malformations of this plant under three heads, as follows:</p>
+
+<div class="blockquot"><p>1. Calyx-teeth larger than usual, sometimes dentate at the
+margin; petals more or less regular and disposed to run away
+from the papilionaceous form; filaments free; anthers normal;
+carpel transformed into a true leaf with a long stalk provided
+at the base, with two stipules, terminal leaflet, solitary,
+green, with no trace of ovules. Sometimes a second carpellary
+leaf, similar to the first, is formed; in other cases the
+central axis of the flower is occasionally prolonged into a
+head of young flowers&mdash;median prolification. In some few
+instances the calyx is not at all altered, but the carpellary
+leaf is trifoliolate, or even quinquefoliolate,<span class='pagenum'><a name="Page_277" id="Page_277">[Pg 277]</a></span> the corolla
+being then absent. The heads of flowers in this first form have
+the aspect of little tufts of leaves.</p>
+
+<p>2. Each of the teeth of the calyx is represented by a long
+stalk, terminated by a single articulated leaflet, the
+bi-labiate form of the calyx is still recognisable; the two
+upper petals are united, the three lower separate; the tube of
+the calyx is not deformed and seems to be formed of the
+petioles of the sepals united by their stipules. In this second
+class of cases the corolla is papilionaceous, the filaments
+free, the carpellary leaf on a long stalk provided with
+stipules, its blade more or less like the usual carpel, with
+its margins disunited or more commonly united with the ovules
+in the interior, sometimes represented by a foliaceous, dentate
+primine only. In one case the carpel was closed above, gaping
+below, where it gave origin to several leaflets, the lower ones
+oval, dentate, like ordinary leaflets, the upper ones merely
+lanceolate, leafy lobes, representing the primine reduced to a
+foliaceous condition. Inflorescence&mdash;a head with leafy flowers
+on long stalks, which are longer at the circumference than in
+the centre.</p>
+
+<p>3. Calyx-teeth lance-shaped, acuminate; corolla more or less
+regular, arrested in its development and scarcely exceeding the
+tube of the calyx within which it is crumpled up; stamens but
+little changed; carpellary leaf on a short stalk, not exceeding
+the calyx tube, but the ovarian portion very long, and provided
+with abortive ovules.</p>
+
+<p>These three groups will be found to include most of the forms
+under which frondescence of the clover blossoms occurs, but
+there are, of course, intermediate forms not readily to be
+grouped under either of the above heads. Such are the cases
+brought under the notice of the British Association at
+Birmingham in 1849 by Mr. R. Austen, in some of which the
+petals and stamens even were represented by leaves. </p></div>
+
+<p>Although, on the whole, chloranthy is most frequent in the families
+already alluded to, yet it is by no means confined to them, as the
+examples now to be given amply show. Specimens of <i>Nymph&aelig;a Lotus</i> have
+been seen in which all the parts of the flower, even to the stigmas,
+were leafy, while the ovules were entirely wanting.</p>
+
+<p>Planchon<a name="FNanchor_288_288" id="FNanchor_288_288"></a><a href="#Footnote_288_288" class="fnanchor">[288]</a> figures and describes a flower of <i>Drosera intermedia</i>
+that had passed into a chloranthic condition, excepting the calyx, which
+was unchanged; the petals, like the valves of the ovary, were provided
+with stipules, and were circinate in vernation. </p><p><span class='pagenum'><a name="Page_278" id="Page_278">[Pg 278]</a></span></p>
+
+<p>M. A. Viaud-Grand-Marais<a name="FNanchor_289_289" id="FNanchor_289_289"></a><a href="#Footnote_289_289" class="fnanchor">[289]</a> records an interesting example of
+chloranthy, in which the sepals, petals, pistils, and ovules of
+<i>Anagallis arvensis</i> were all foliaceous. Similar changes have not
+unfrequently been met with in <i>Dictamnus Fraxinella</i>.</p>
+
+<p>M. Germain de Saint Pierre has also recorded the following deviations in
+the flowers of <i>Rumex arifolius</i> and <i>R. scutatus</i>; in these specimens
+the calyx was normal, the petals large, foliaceous, shaped like the
+stem-leaves, the stamens were absent, the three carpels fused into a
+triangular leafy pod, as long again as the perianth, the stigmas normal
+or wanting, the ovule represented by a thick funicle, terminated by a
+foliaceous appendage analogous to the primine.<a name="FNanchor_290_290" id="FNanchor_290_290"></a><a href="#Footnote_290_290" class="fnanchor">[290]</a></p>
+
+<p>In grasses it frequently happens that the flowers are replaced by
+leaf-buds; this condition is alluded to elsewhere under the head of
+viviparous grasses, but in this place may be mentioned a less degree of
+change, and which seems to have been a genuine case of chloranthy in
+<i>Glyceria fluitans</i>, the spikelet of which, as observed by Wigand,<a name="FNanchor_291_291" id="FNanchor_291_291"></a><a href="#Footnote_291_291" class="fnanchor">[291]</a>
+consisted below of the ordinary unchanged glumes, but the remaining
+pale&aelig; as well as the lodicles and stamens were represented by ligulate
+leaves. The plant, it is stated, was affected by a parasitic fungus. On
+the other hand, General Munro, in his valuable monograph of the
+<i>Bambusace&aelig;</i>,<a name="FNanchor_292_292" id="FNanchor_292_292"></a><a href="#Footnote_292_292" class="fnanchor">[292]</a> refers to an illustration in which "the lowest glumes
+generally, and the lowest pale&aelig; occasionally, had the appearance of
+miniature leaves, with vagin&aelig;, ligules and cilia, enveloping, however,
+perfect fertile spicul&aelig;; as progress is made towards the top of the
+spike, the ligule first, then the cilia, and finally, the leaf-like
+extension disappears, and the uppermost glumes assume the ordinary shape
+and form of those organs."</p>
+
+
+
+<p><b>General remarks on chloranthy and frondescence.</b>&mdash;Moquin<span class='pagenum'><a name="Page_279" id="Page_279">[Pg 279]</a></span> remarks with
+justice that the position of the flowers on the axis is of importance
+with reference to the existence of chloranthy. Terminal flowers are more
+subject to it than lateral ones, and if the latter, by accident, become
+terminal, they seem peculiarly liable to assume a foliaceous condition.
+Kirschleger says, that in <i>Rubus</i> there are two sorts of chloranthy,
+according as the anomaly affects the ordinary flowering branches, or the
+leafy shoots of the year, the summits of which, instead of developing in
+the customary manner, terminate each in one vast and long inflorescence,
+very loose and indeterminate, and with axillary flowers.<a name="FNanchor_293_293" id="FNanchor_293_293"></a><a href="#Footnote_293_293" class="fnanchor">[293]</a></p>
+
+<p>On the whole, taking in consideration cases of partial frondescence, as
+well as those in which most of the parts of the flower are affected,
+phyllody would seem to be most common in the petals and carpels, least
+so in the case of the stamens and sepals. It is more common among
+polysepalous and polypetalous plants than in those in which the sepals
+or petals are united together.</p>
+
+<p>The causes assigned for these phenomena are chiefly those of a nature to
+debilitate or injure the plant; thus it has been frequently observed to
+follow the puncture of an insect. M. Guillard<a name="FNanchor_294_294" id="FNanchor_294_294"></a><a href="#Footnote_294_294" class="fnanchor">[294]</a> gives an instance in
+<i>Stellaria media</i> where the condition appeared to be due to the attacks
+of an insect <i>Thrips fasciata</i>. Still more commonly it arises from the
+attacks of parasitic fungi, <i>e.g.</i> <i>Uredo candida</i>, in Crucifers, &amp;c.</p>
+
+<p>In other cases it has been observed when the plants have been growing in
+very damp places, or in very wet seasons, or in the shade, or where the
+plant has been much trampled on. This happens frequently with <i>Trifolium
+repens</i>. The frequency with which the change is encountered in this
+particular species is very remarkable; it is difficult to see why one
+species should be so much more subject to the kind of change than
+another of nearly identical conformation.</p>
+
+<p><span class='pagenum'><a name="Page_280" id="Page_280">[Pg 280]</a></span>It might at first be supposed that the same causes that bring about the
+complete substitution of leaf-buds for flower-buds (see Heterotaxy)
+would operate also in the partial substitution of leaves for other parts
+of the flower, but it will be seen that the inducing cause, whether
+similar or not in the two cases respectively, acts at different times;
+in the one case, it is not brought into play until the rudiments of the
+flower are already formed, whereas in the other the influence is exerted
+prior to the formation of the flower. So that while the formation of
+leaf-buds in place of flower-buds may be and generally is due to an
+excess of nutrition, inducing over activity of the vegetative organs,
+the production of phyllomorphic or chloranthic flowers may be owing
+rather to a perversion of development arising from injury or from some
+debilitating agency. The discrepancies in the assigned causes for the
+conditions above mentioned may, therefore, in great measure, be
+attributed to the different periods at which the causes in question
+operate.</p>
+
+<p>The following list may serve as a guide to the plants most frequently
+the subjects of chloranthy, but reference should also be made to
+preceding and subsequent sections, and to that relating to prolification
+of the inflorescence.</p>

+well seen in cases like <i>Mussaenda</i>, <i>Calycophyllum</i>, or
+<i>Dipterocarpus</i>, where the enlarged calycine segment has a strictly
+vaginal arrangement of its veins, very different from that which occurs
+in the true leaf-blades. These are cases, therefore, where the sheath of
+the leaf is unusually enlarged, and are not to be referred, as is often
+done, to metamorphosis of one or more sepals to perfect leaves.
+Prolified roses, cherries, &amp;c., furnish frequently parallel cases. With
+reference to <i>Mussaenda</i>, C. Morren held the view that the petal-like
+sepal was really a bract adherent to the calyx, and incorporating with
+itself one of the calycine lobes&mdash;"soud&eacute;e au calice et ayant d&eacute;vor&eacute;e, en
+englobant dans sa propre masse, un lobe calicinal." The Belgian <i>savant</i>
+considers this somewhat improbable explanation as supported by a case
+wherein there were five calyx lobes of uniform size, and a detached
+feather-veined leaf proceeding from the side of the ovary lower down
+('Bull. Acad. Belg.,' xvii, p. 17, <i>Fuchsia</i>, p. 169).</p></div>

+strawberry," and very little is known of it in this country, or on the
+continent, the author gladly avails himself of this opportunity of
+inserting an account of it, for which he is indebted to the kindness of
+Dr. Robert Hogg.&mdash;The Plymouth Strawberry (<i>Fragaria vesca fructu
+hispido</i>) is a sort of botanical Dodo upon which many have written, and
+which few have seen. Many years have elapsed since it was first
+discovered; and although a century and a half have passed since there
+was any evidence of its existence, it serves still as an illustration
+for students in morphology of one of those strange abnormal structures
+with which the vegetable kingdom abounds.
+</p><p>
+It is to old John Tradescant we are indebted for the earliest record of
+this plant. Johnson, in his edition of 'Gerard,' says; "Mr. John
+Tradescant hath told me that he was the first that tooke notice of this
+strawberry, and that in a woman's garden at Plimouth, whose daughter had
+gathered and set the roots in her garden, in stead of the common
+strawberry; but she, finding the fruit not to answer her expectation,
+intended to throw it away; which labour he spared her in taking it and
+bestowing it among the louers of such varieties, in whose garden it is
+yet preserved." Doubtless one of those "lovers" was his friend John
+Parkinson, who, in the year 1629, thus wrote concerning it: "One
+strawberry more I promised to shew you, which, although it be a wilde
+kinde, and of no vse for meate, yet I would not let this discourse passe
+without giuing you the knowledge of it. It is in leafe much like vnto
+the ordinary, but differeth in that the flower, if it haue any, is
+greene, or rather it beareth a small head of greene leaues, many set
+thicke together like vnto a double ruffe, in the midst whereof standeth
+the fruit, which, when it is ripe, sheweth to be soft and somewhat
+reddish, like vnto a strawberry, but with many small harmlesse prickles
+on them which may be eaten and chewed in the mouth without any maner of
+offence and is somewhat pleasant as a strawberry; it is no great bearer,
+but those it doth beare, are set at the toppes of the stalks close
+together, pleasant to behold, and fit for a gentlewoman to weare on her
+arme, &amp;c., as a rairitie in stead of a flower."
+</p><p>
+Merret, in his 'Pinax.' published in 1667, says he found it growing in
+the woods of Hyde Park and Hampstead, and Zanoni was the first to figure
+it (with the exception of Parkinson's rude woodcut) in his 'Istoria
+Botanica,' published in 1675. It is mentioned by Morison and also by
+Ray, the latter of whom inserts it in his Synopsis, but without any
+habitat; though in his 'Historia Plantarum' he says: "Cantabrigi&aelig; in
+horto per aliquot annos colui." From this time henceforth the Plymouth
+strawberry has become a botanical Dodo, nothing more having been seen or
+heard of it except the mere record of the name. In 1766, M. Duchesne
+informed the world of the generosity of "M. Monti, Docteur de
+Philosophie et de M&eacute;decine &agrave; Boulogne en Italie," who divided with him a
+dried specimen taken from his own herbarium, "Ce pr&eacute;sent pr&eacute;tieux m'&ocirc;te
+toute incertitude sur la nature de ce Fraisier et sur ses caract&egrave;res
+monstrueux. Il paro&icirc;t ne pas avoir aujourd'hui plus d'existence."</p></div>

+
+METAMORPHY OF THE FLORAL ORGANS.</h4>
+
+
+<p>One of the main arguments adduced by Goethe and others in support of the
+now generally received doctrine of the essential morphological identity
+of the various whorls of the flower is derived from the frequent
+appearance of one organ in the guise of another. The several parts of
+the flower become, as it is said,<span class='pagenum'><a name="Page_282" id="Page_282">[Pg 282]</a></span> metamorphosed; sometimes the change
+is complete, while at other times there may be every conceivable
+intermediate condition between one form and another. The sense in which
+the terms metamorphosis, substitution, transformation, and the like, are
+herein used has already been explained. For the convenience of
+arrangement, metamorphosis of the parts of the flower may be divided
+into several subdivisions, according to the particular organ affected,
+and according to the special kind or degree of change manifested, the
+main subdivisions being here classed as Sepalody, Petalody, Staminody,
+and Pistillody.</p>
+
+
+
+<p><b>Sepalody of the petals.</b>&mdash;This change, spoken of by most authors as
+retrograde metamorphosis of the petals into sepals, or as a substitution
+of sepals for petals, is obviously a condition that is in most cases
+hardly distinguishable from virescence of the corolla, or from
+multiplication of the sepals. Nor is this of much consequence unless
+there are some special structural features which render the
+discrimination a matter of importance, in which case the difficulty is
+generally easily surmounted. The flower of the Saint-Val&egrave;ry Apple may
+perhaps be cited under this head. In the flower in question there are
+neither stamens nor petals, unless the second or inner of sepals be
+considered as sepaloid petals (fig. 152).</p>
+

+<p class="caption"> <span class="smcap">Fig.</span> 152.&mdash;Flower of St. Val&egrave;ry apple, with sepaloid petals.</p>
+</div>
+
+<p>M. Alph. de Candolle<a name="FNanchor_295_295" id="FNanchor_295_295"></a><a href="#Footnote_295_295" class="fnanchor">[295]</a> describes an instance in <i>Primula Auricula</i> in
+which the corolla had assumed the appearance of the calyx, but neither
+calyx nor corolla in this case possessed perfect stomata.</p>
+
+<p>This malformation is much less common than the converse one of
+calycanthemy. Many of the recorded instances of so-called metamorphosis
+of the parts of<span class='pagenum'><a name="Page_283" id="Page_283">[Pg 283]</a></span> the flower to sepals have occurred in monocotyledonous
+plants, or others in which the calyx and corolla are of the same colour,
+and constitute what is frequently termed the perianth; and as this is
+usually brightly coloured (not green) it is more convenient to group the
+metamorphoses in question under the general term Petalody, which thus
+includes all those cases in which the organs of the flower appear in the
+form of coloured petal-like organs, whether they be true petals or
+segments of a coloured perianth. As the morphological difference between
+the organs is one of position merely, there is little objection to be
+raised to this course, the less so as the term petalody merely conveys
+an idea of resemblance and not of absolute identity.</p>
+
+<p>Petaloid coloration of the ordinary leaves, or of the bracts, is
+mentioned under the chapter relating to colour.</p>
+
+
+
+<p><b>Petalody of the calyx&mdash;Calycanthemy.</b>&mdash;As with the bracts, so the calyx
+in certain instances is naturally coloured, as in <i>Delphinium</i>,
+<i>Trop&aelig;olum</i>, and others. In <i>Muss&aelig;nda</i>, <i>Calycophyllum</i>, <i>Usteria</i>, &amp;c.,
+one or more of the calyx lobes become enlarged normally. Considered
+teratologically, petaloid coloration of the sepals is either general or
+partial; in the latter case the nerves retain their green colour
+longest. There is in cultivation a variety of the primrose called
+<i>Primula calycanthema</i>, in which the upper part of the calyx becomes
+coloured, so that the flower seems to have two corollas placed one
+within the other; a similar thing happens in <i>Mimulus</i>, in which plant,
+as the calyx is permanent while the corolla is deciduous, the coloured
+calyx is a great advantage in a horticultural point of view. Morren<a name="FNanchor_296_296" id="FNanchor_296_296"></a><a href="#Footnote_296_296" class="fnanchor">[296]</a>
+says that in order to produce the fine colour of the calyx of <i>Primula
+officinalis</i> (var. <i>smaragdina</i>) the Belgian gardeners cut away the
+corolla in a very early stage, and that in consequence the colouring
+matter<span class='pagenum'><a name="Page_284" id="Page_284">[Pg 284]</a></span> proper to the corolla is developed in the tube of the calyx, the
+edges of the limb remaining green, the middle of the limb being purple
+(<i>Primula tricolor</i>).</p>
+
+<div class="center">
+ <a name="fig153" id="fig153"></a>
+<a href="images/fig153m.jpg">

+    title="" />
+  </a>
+<p class="caption"> <span class="smcap">Fig.</span> 153.&mdash;Flower of <i>Mimulus</i>, with petaloid calyx.</p>
+</div>
+
+<p>Under this head may be mentioned the occurrence of tubular sepals in
+place of the ordinary flat ones in <i>Helleborus olympicus</i>; only two of
+the sepals were thus affected in a specimen recently observed&mdash;a third
+exhibited an intermediate condition.</p>
+
+<p>The normal coloration of the calyx occurs most frequently in
+polysepalous calyces; teratological coloration, on the other hand,
+occurs especially in gamosepalous flowers. This assertion is borne out
+by the frequency of the change in the plants already mentioned, and also
+in the following:&mdash;<i>Campanula persicifolia</i>, <i>Anagallis arvensis</i>,
+<i>Gloxinia</i>, <i>Syringa persica</i>,<a name="FNanchor_297_297" id="FNanchor_297_297"></a><a href="#Footnote_297_297" class="fnanchor">[297]</a> <i>Calceolaria</i>, <i>&amp;c. &amp;c.</i> In the
+last-named plant one or more of the lobes of the calyx may frequently be
+seen replaced by a slipper-like petal. </p><p><span class='pagenum'><a name="Page_285" id="Page_285">[Pg 285]</a></span></p>
+
+<p>Among polysepalous plants petaloid sepals have been observed in
+<i>Ranunculus auricomus</i>, <i>Rubus c&aelig;sius</i>, <i>&amp;c.</i> Fleischer also describes a
+case of this kind in <i>Carum carui</i>.<a name="FNanchor_298_298" id="FNanchor_298_298"></a><a href="#Footnote_298_298" class="fnanchor">[298]</a></p>
+
+<p>It will be seen from the above that in the majority of cases there is no
+real metamorphosis or substitution of petal for calyx, but simply an
+alteration in colour; nevertheless, a change in form may accompany a
+change of colour: this happens especially if there has been any
+displacement of organs. Thus, if, in an orchidaceous plant, a sepal be
+displaced from any cause, or a petal be twisted out of its natural
+position to occupy the place of an absent sepal, that petal will be
+sepal-like in form, and <i>vice vers&acirc;</i>.</p>
+
+
+
+<p><b>Petalody of the stamens.</b>&mdash;A petaloid condition of the stamens is one of
+the commonest of all malformations. A large number of so-called double
+flowers (flores pleni)<a name="FNanchor_299_299" id="FNanchor_299_299"></a><a href="#Footnote_299_299" class="fnanchor">[299]</a> owe their peculiar appearance to this
+circumstance.</p>
+
+<p>It is necessary to distinguish carefully this petaloid development of
+the stamens from the corresponding condition of the pistils, and from
+that kind of doubling which is a result of multiplication of the
+corolla, as in <i>Datura</i>, <i>Campanula</i>, <i>Primula</i>, &amp;c. (flores duplices,
+triplices, &amp;c.), or from that produced by true median prolification
+(flores geminati, &amp;c.).</p>
+
+<p>In cases of true petaloid development of the stamens there are usually
+numerous intermediate forms between that of the true petals and that of
+the perfect stamens; indeed, in <i>Nymph&aelig;a</i>, <i>Canna</i>, and in some other
+plants, such a transition occurs normally. Petalody of the stamens may
+occur either without material change in the flower or it may exist in
+combination or in conjunction with an increased development of parts
+(Multiplication), or with a similar change in the carpels, and it is
+either partial or complete.</p>
+
+<p><span class='pagenum'><a name="Page_286" id="Page_286">[Pg 286]</a></span>Among the flowers in which petaloid development of the stamens happens
+most frequently may be mentioned those in which the calyx is normally
+coloured, as in <i>Nigella damascena</i>, <i>Aguilegia</i>, and <i>Delphinium</i>.</p>
+
+<p>M. Alph. de Candolle, in the 'Neue Denkschriften,' 1841, described and
+figured a singular form of <i>Viola odorata</i>, known under the name of
+"Bruneau," in Switzerland, in which the stamens are absent, and their
+place supplied by a second row of petals, within which is a third series
+of petals, representing, says M. de Candolle, the inner row of stamens
+that theory suggests should exist in the natural condition. Moreover,
+the carpels in this variety are five in number instead of three. In
+<i>Erica Tetralix</i> the corolla may not unfrequently be found divided to
+the base into its constituent petals, and the place of the stamens
+occupied by a series of petal-like structures entirely destitute of
+anther.</p>
+
+<p>In monocotyledonous flowers, especially those with a coloured perianth,
+the substitution of segments of the perianth for stamens occurs not
+unfrequently. M. Seringe has observed this in the stamens of <i>Lilium
+Martagon</i>, and there is in cultivation a variety of the white lily,
+<i>Lilium candidum</i>, sometimes called the double white lily, in which the
+segments of the perianth, in place of being arranged in two rows, are
+greatly increased in number, and disposed in a spiral manner. In these
+flowers, not only are the stamens and pistils thus modified, but also
+the upper leaves of the stem. In so-called double tulips there is
+likewise a replacement of stamens by coloured segments of the perianth,
+but this happens generally in connection with an increase in the number
+of organs. Moquin-Tandon remarks having seen in a garden in the environs
+of Montpelier a tulip, the stamens of which showed all possible stages
+of transition between the form proper to them and that of the perianth.
+The pistil in this case was transformed into several small leaves.
+Similar appearances have been observed in Iris, Hyacinths, Narcissus,<span class='pagenum'><a name="Page_287" id="Page_287">[Pg 287]</a></span>
+Colchicum, and Crocus. M. Fournier<a name="FNanchor_300_300" id="FNanchor_300_300"></a><a href="#Footnote_300_300" class="fnanchor">[300]</a> describes a flower of <i>Narcissus
+Tazetta</i> from within the normal perianth of which sprang a second one,
+equally provided with a cup and occupying the space usually filled by
+the stamens. Flowers of <i>Narcissus poeticus</i> may also be met with in
+which the stamens are replaced by six distinct segments exactly
+resembling those of the perianth in miniature.<a name="FNanchor_301_301" id="FNanchor_301_301"></a><a href="#Footnote_301_301" class="fnanchor">[301]</a></p>

+</div>
+
+<p>From an examination of these flowers it becomes evident that
+petalification is brought about in different flowers in different ways;
+sometimes it is the filament which becomes petaloid, sometimes the
+anther-lobes, while at other times it is the connective which assumes
+the appearance of petals.<a name="FNanchor_302_302" id="FNanchor_302_302"></a><a href="#Footnote_302_302" class="fnanchor">[302]</a> For instance, in <i>Solanum</i><span class='pagenum'><a name="Page_288" id="Page_288">[Pg 288]</a></span> <i>tuberosum</i>,
+<i>S. Dulcamara</i>, in <i>Anagallis</i>, in <i>Fuchsia</i>, and some other plants, the
+anther-lobes themselves become petaloid, while the filament remains
+unchanged.</p>
+
+<p>In gardens two distinct varieties of Columbine are cultivated, the one
+in which the filaments are dilated into the form of flat petals almost
+entirely or quite destitute of anthers, while in the other the filament
+is present in its usual form, but the anther is developed in the shape
+of a tubular hood or spur.</p>
+
+<p>De Candolle<a name="FNanchor_303_303" id="FNanchor_303_303"></a><a href="#Footnote_303_303" class="fnanchor">[303]</a> observes that in the <i>Ranunculace&aelig;</i> the species of
+<i>Clematis</i> become double by the expansion of the filament, those of
+<i>Ranunculus</i> by the dilatation of the anther, and those of <i>Helleborus</i>
+by the petal-like development of both filament and anther. In some cases
+even on the same plant all three modifications may be seen, as in
+Camellias, some of which may be found with petaloid filaments with
+anthers on the top, others with the filaments unchanged, but supporting
+petaloid anthers, while in others it is the connective alone which is
+petal-like. Where the flower naturally contains a large number of
+stamens, as in Mallows, Roses, Magnolias, &amp;c., petaloid expansion of the
+filament is most common, though it is by no means confined to such
+flowers, the change occurring in <i>Allamanda cathartica</i>, <i>Jasminum
+grandiflorum</i>, and many other flowers with few stamens. A similar change
+in the anther and connective takes place more frequently in flowers
+where the number of stamens is smaller, but there are of course numerous
+exceptions to this rule.</p>
+
+<p>In those cases where there is more than one row of stamens, the
+outermost are most liable to this change: thus in <i>Saxifraga decipiens</i>,
+as shown by Ch. Morren,<a name="FNanchor_304_304" id="FNanchor_304_304"></a><a href="#Footnote_304_304" class="fnanchor">[304]</a> the outer series of stamens&mdash;those opposite
+to the sepals&mdash;become first affected, and, at a more advanced stage, the
+inner row also; and this is the case in most<span class='pagenum'><a name="Page_289" id="Page_289">[Pg 289]</a></span> flowers that have their
+stamens in two rows. Occasionally it happens that an outer series of
+stamens is abortive, or wholly suppressed, while the inner row becomes
+petalodic; this was the case in some flowers of <i>Lilium auratum</i> lately
+exhibited by Messrs. Veitch.</p>
+
+<p>Those flowers in which only a portion of the stamens undergo this change
+are called semi-double, while in other cases that will be hereafter
+mentioned, not only are the stamens thus rendered petaloid, but their
+number is also augmented, as in most double roses, pinks, anemones,
+poppies, &amp;c.</p>
+
+<p>In some double flowers, in which the stamens assume more or less
+completely the appearance of petals, a singular appearance is afforded
+by the presence of four wing-like processes emanating from the central
+filaments, two on each side, so that the arrangement may be compared to
+two sheets of paper folded in the centre and adherent in that situation,
+though perfectly separate elsewhere, except sometimes at the top, where
+they form a sort of hood. This change results from an imperfect petalody
+of the anther; the two wings on each side of the central vascular cord
+represent the front and back walls of an anther lobe, or rather of that
+portion of the anther which, under ordinary circumstances, produces
+pollen. In the malformed flowers no pollen is formed, at least in the
+more complete states of the malformation, but the walls of the anther
+lobe become preternaturally enlarged, and petaloid in texture and
+appearance. This change occurs in some semi-double rhododendrons and
+azaleas, in crocuses, and in a species of violet found at Mentone by Mr.
+J. T. Moggridge.</p>
+
+<p>There are numerous intermediate forms wherein the wing-like processes
+may be traced all the way along the filament till they ultimately lose
+themselves in the anther-lobes, with which they become continuous. In
+some cases, as in <i>Crocus</i> and <i>Rhododendron</i>, this is shown even more
+clearly by the existence of two perfect pollen-sacs or quarter-anthers,
+the remaining portions<span class='pagenum'><a name="Page_290" id="Page_290">[Pg 290]</a></span> being petaloid and continuous with the dilated
+filament. Not unfrequently these semi-petaloid stamens adhere to the
+fronts of the petals, and then it appears, at a first glance, as if
+three organs were stuck together, one in front of another, while in
+reality there are but two.<a name="FNanchor_305_305" id="FNanchor_305_305"></a><a href="#Footnote_305_305" class="fnanchor">[305]</a> (See <i>ant&egrave;</i>, p. 35, fig. 12.)</p>

+
+<p>The change in the anther, above alluded to, must not be mistaken for
+that far more common one in which only a small portion of the anther
+becomes petaloid, forming a sort of lateral wing or appendage to the
+polliniferous portion, as happens normally in <i>Pterandra</i>, and is common
+in some double fuchsias. In this latter instance there is but a single
+wing, and the nature of the case is obvious.</p>
+
+<p>Double flowers of <i>Orchidace&aelig;</i> generally arise from petalification of
+the filaments, with or without other coincident changes. What makes
+double flowers in this order the more interesting is the development, in
+a petaloid condition, of some or all of those stamens which under
+ordinary circumstances are wholly suppressed, so that the morphological
+structure of the flower, at first a matter of theory, becomes actually<span class='pagenum'><a name="Page_291" id="Page_291">[Pg 291]</a></span>
+realised. Fig. 156 is a diagram showing the presence of two additional
+labella within the ordinary one in a species of <i>Catasetum</i>, and
+representing two petaloid stamens, thus evidently completing the outer
+staminal whorl, of which there is usually but a single representative
+(see Peloria, Multiplication, Prolification). In some of these double
+orchids it is, however, necessary not to confound a petaloid condition
+of the existing column with the development of usually suppressed
+stamens in a petaloid form. Thus, in <i>Lycaste Skinneri</i> the column is
+frequently provided with two petal-like wings, which might readily be
+supposed to be two stamens of the inner whorl adherent to the column; a
+little attention, however, to the relative position of these
+adventitious wings is generally sufficient to enable the observer to
+ascertain the true nature of the appearance.<a name="FNanchor_306_306" id="FNanchor_306_306"></a><a href="#Footnote_306_306" class="fnanchor">[306]</a></p>

+
+<p>Some forms of duplicate or hose in hose corollas are apparently due, not
+so much to the formation of a second corolla within the first, as to the
+presence of an inner series of petal-like stamens, which, by their
+cohesion, form a second pseudo-corolla within the first. The staminal
+nature of this pseudo-corolla is inferred from the occasional presence
+of anthers on it.<a name="FNanchor_307_307" id="FNanchor_307_307"></a><a href="#Footnote_307_307" class="fnanchor">[307]</a> In <i>Datura fastuosa</i>, as well as in <i>Gloxinia</i>, a
+pseudo-corolla of this kind sometimes occurs with the addition of a

+
+<p>When the petalody specially affects the anther-lobes, as in <i>Arbutus</i>,
+<i>Petunia</i>, <i>Fuchsia</i>, <i>&amp;c.</i>, the venation of the petal-like portion is
+very frequently laminar, thus<span class='pagenum'><a name="Page_292" id="Page_292">[Pg 292]</a></span> tending to show that the anther is in
+such cases really a modification of the blade of the leaf; but as, on
+the other hand, we often find petal-like filaments bearing pollen-sacs
+on their sides, it is clear that we must not attribute the formation of
+pollen to the blade of the leaf only, but we must admit that it may be
+formed in the filament as well.<a name="FNanchor_309_309" id="FNanchor_309_309"></a><a href="#Footnote_309_309" class="fnanchor">[309]</a> </p><p><span class='pagenum'><a name="Page_293" id="Page_293">[Pg 293]</a></span></p>

+
+<p>Petalody of the connective is of less frequent occurrence than the
+corresponding change in the other portions of the stamen. It may be seen
+in some forms of double columbine,<a name="FNanchor_310_310" id="FNanchor_310_310"></a><a href="#Footnote_310_310" class="fnanchor">[310]</a> in which the connective forms a
+tubular petal or nectary, and in double petunias and fuchsias. When it
+occurs, the true<span class='pagenum'><a name="Page_294" id="Page_294">[Pg 294]</a></span> anther-lobes are usually atrophied, and little or no
+pollen is formed.</p>
+
+<p>An occurrence of this nature in <i>Tacsonia pinnatistipula</i>, in
+conjunction with the partial detachment of the stamens from the
+gynophore, led Karsten to establish a genus which he called
+<i>Poggendorffia</i>.<a name="FNanchor_311_311" id="FNanchor_311_311"></a><a href="#Footnote_311_311" class="fnanchor">[311]</a></p>
+
+<p>From the subjoined list of genera in which petalody of the stamens, in
+some form or other, has been observed, it will be seen that it happens
+more often in plants with numerous distinct organs (Polypetal&aelig;,
+Polyandria, Polygynia, &amp;c.) than in other plants with a smaller number
+of parts, and which are more or less adherent one to the other. The
+tendency to petalification is, moreover, greater among those plants
+which have their floral elements arranged in spiral series, than among
+those where the verticillate arrangement exists; and in any given
+flower, if the stamens are spirally arranged while the carpels are
+grouped in whorls, the former will be more liable to petalody than the
+latter, and <i>vice vers&acirc;</i>. It has been before remarked, that this
+condition is far more common in plants whose petals, &amp;c., have straight
+veins, like those in the sheath of a leaf, than in those the venation of
+which is reticulate, as in the blade of the leaf. It must also be
+remembered that in the same genus, even in the same species, different
+kinds of doubling occur. Familiar illustrations of this are afforded in
+the case of anemones, columbines, fuchsias, and other plants.</p>
+
+<p>The existence of "compound stamens" in some flowers, as pointed out by
+Payer, and others, and the researches of Dr. Alexander Dickson, confer
+additional importance on the subject of petalody, and necessitate the
+examination of double flowers with special reference to these compound
+stamens, and to the order of their development.<a name="FNanchor_312_312" id="FNanchor_312_312"></a><a href="#Footnote_312_312" class="fnanchor">[312]</a> The presence of
+these compound stamens<span class='pagenum'><a name="Page_295" id="Page_295">[Pg 295]</a></span> affords a satisfactory explanation of the
+appearance in some double <i>Malvace&aelig;</i>, wherein the tufts of adventitious
+petals are very liable to be mistaken for buds, produced by axillary
+prolification in the axils of the petals, but which are in reality
+compound and petaloid stamens. At other times, however, true axillary
+prolification exists in these flowers; but then the supplemental florets
+have always a calyx, which is wanting in the other instances.</p>

+<p><b>Petalody of the pistils.</b>&mdash;Taken by itself, this is much less common than
+the corresponding change in the stamens. It generally affects the style
+and stigma only, as happens normally in <i>Petalostylis</i>, <i>Iris</i>, &amp;c., but
+this is by no means always necessarily the case. In some of the
+cultivated varieties of <i>Anemone</i> and <i>Ranunculus</i> all the parts of the
+flower remain in their normal state, except the pistils, which latter
+assume a petaloid appearance.</p>
+
+<p>Many of the double flowers owe their peculiar appearance to the
+combination of the following appearances&mdash;a petal-like form of the
+stamens, increase in<span class='pagenum'><a name="Page_297" id="Page_297">[Pg 297]</a></span> the number of these organs and similar changes
+affecting the pistils, and is applied to several distinct conditions. If
+in any given flower all the stamens and all the pistils become wholly
+petaloid, no pollen is formed, and of course no seeds can be produced,
+but this very rarely happens, as usually some pollen is produced, and
+some ovules capable of being fertilised are developed.</p>
+
+<p>In double flowers of <i>Primula sinensis</i> it frequently happens that the
+capsule is either partially leafy or partly petal-like; in either case
+the fruit is open at the extremity, and often destitute of the style and
+stigma. It is, however, doubtful if the ovules can be fertilised in
+these flowers.</p>
+
+<p>The following list comprises the names of those genera in which this

+petaloid state. Reichenbach<a name="FNanchor_321_321" id="FNanchor_321_321"></a><a href="#Footnote_321_321" class="fnanchor">[321]</a> figures an illustration of this change,
+and also Moggridge.<a name="FNanchor_322_322" id="FNanchor_322_322"></a><a href="#Footnote_322_322" class="fnanchor">[322]</a></p>
+
+
+
+<p><b>Staminody of the pistils.</b>&mdash;The existence of this change has been denied
+by several authors, nevertheless, it is of sufficiently common
+occurrence. Alexander Braun notices the transformation of pistils into
+stamens in Chives (<i>Allium Scorodoprasum</i>), and in which three stamens
+appeared in the place of as many pistils, and had extrorse anthers,
+while the six normal anthers are introrse. In the horse-radish
+(<i>Armoracia rusticana</i>), two of the carpels are frequently converted
+into stamens, while two other organs absent from the normal flower make
+their appearance as carpels. Roeper has observed this phenomenon in
+<i>Euphorbia palustris</i>,<a name="FNanchor_323_323" id="FNanchor_323_323"></a><a href="#Footnote_323_323" class="fnanchor">[323]</a> and in <i>Gentiana campestris</i>.<a name="FNanchor_324_324" id="FNanchor_324_324"></a><a href="#Footnote_324_324" class="fnanchor">[324]</a> In these
+examples one of the carpels was apparently absent, and its place
+supplied by an anther. Roeper has also mentioned a balsam with a
+supernumerary stamen occupying exactly the position of a carpel.<a name="FNanchor_325_325" id="FNanchor_325_325"></a><a href="#Footnote_325_325" class="fnanchor">[325]</a></p>
+
+<p>Agardh has observed a similar thing in a hyacinth, one half of the fruit
+of which contained seeds, and the other half, anthers. B. Clarke
+mentions an instance in <i>Mathiola incana</i> in which the carpels were
+disunited, and antheriferous at the margin.<a name="FNanchor_326_326" id="FNanchor_326_326"></a><a href="#Footnote_326_326" class="fnanchor">[326]</a></p>
+
+<p>The passage of pistils to stamens in willows has been frequently
+remarked, as in <i>Salix babylonica</i>, <i>silesiaca</i>, <i>cinerea</i>, <i>Caprea</i> and
+<i>nigricans</i>. One of the most curious illustrations of this
+transformation in this genus is given by Henry and Macquart (Erst.
+Jahrb. des bot. Vereines am m. et n. Rhein., 1837). In the flowers in<span class='pagenum'><a name="Page_300" id="Page_300">[Pg 300]</a></span>
+question the series of changes were as follows:&mdash;first, the ovary opened
+by a slit, and then expanded into a cup; next, anther-cells were
+developed on the margin of the cup, with stigmas alternating with them,
+the ovules at the same time disappearing; lastly, the margin became
+divided, and bore three perfect anthers, which in the more perfect
+states were raised on three filaments.</p>
+
+<p><i>Campanula persicifolia</i>, <i>C. rapunculoides</i>, and <i>C. glomerata</i> have
+been observed to present an anther surmounting the pistil.<a name="FNanchor_327_327" id="FNanchor_327_327"></a><a href="#Footnote_327_327" class="fnanchor">[327]</a> Double
+tulips often present this change, and a like appearance has been
+observed in <i>Galanthus nivalis</i>, and <i>Narcissus Tazetta</i>.</p>
+
+<p>Moquin mentions the existence of this condition in a female plant of
+maize, some of the pistils of which were wholly or partially converted
+into anther-like organs. Mohl has recorded an analogous malformation in
+<i>Cham&aelig;rops humilis</i>, and in which the three carpels were normally
+formed, and only differed from natural ovaries in this, that along the
+two edges of the ventral suture there was a yellow thickening, which a
+cross section of the ovary showed to be an anther-lobe filled with
+pollen.<a name="FNanchor_328_328" id="FNanchor_328_328"></a><a href="#Footnote_328_328" class="fnanchor">[328]</a></p>
+
+<p>In <i>Tofieldia calyculata</i> a similar substitution of a stamen for a
+carpel has been observed by Klotsch,<a name="FNanchor_329_329" id="FNanchor_329_329"></a><a href="#Footnote_329_329" class="fnanchor">[329]</a> and Weber<a name="FNanchor_330_330" id="FNanchor_330_330"></a><a href="#Footnote_330_330" class="fnanchor">[330]</a> gives other
+instances in <i>Prunus</i> and <i>P&aelig;onia</i>. Corresponding alterations may be met
+with in cultivated tulips, in the cowslip and other plants. In most of
+the above cases the transmutation has been perfect, but in quite an
+equal number of cases a portion only of the carpel is thus changed,
+generally the style or the stigma; thus Baillon describes the stigmas of
+<i>Ricinus communis</i> as having been in one instance<span class='pagenum'><a name="Page_301" id="Page_301">[Pg 301]</a></span> antheriferous.<a name="FNanchor_331_331" id="FNanchor_331_331"></a><a href="#Footnote_331_331" class="fnanchor">[331]</a>
+Moggridge figures a flower of <i>Ophrys insectifera</i> in which the
+rostellate process was replaced by an anther.<a name="FNanchor_332_332" id="FNanchor_332_332"></a><a href="#Footnote_332_332" class="fnanchor">[332]</a></p>
+
+<p>Mohl remarks that the change of pistils into stamens is more common in
+monocarpellary pistils than it is in those which are made up of several
+carpels. It seems clear that in this transformation the lobes of the
+anther and the development of pollen have no relation to the production
+of ovules.</p>
+
+
+
+<p><b>Staminody of the accessory organs of the flower.</b>&mdash;The scales that are
+met with in some plants, either as excrescences from the petals, or as
+imperfect representatives of stamens or other organs, are occasionally
+staminoid; thus the scales of <i>Saponaria officinalis</i>, of <i>Silene</i>,
+<i>Nerium Oleander</i>, the rays of <i>Passiflora</i>, the corona of <i>Narcissus</i>,
+have all been observed occasionally to bear anthers.<a name="FNanchor_333_333" id="FNanchor_333_333"></a><a href="#Footnote_333_333" class="fnanchor">[333]</a> In the case of
+<i>Narcissus</i> the loose spongy tissue of the corona seems to have the
+nearest analogy to the anther-lobes, while the prolonged connective is
+more like the ordinary segments of the perianth in texture. The species
+in which this change may most frequently be observed are, <i>N. poeticus</i>,
+<i>N. incomparabilis</i>, and <i>N. montanus</i>.</p>
+
+<p>M. Bureau found in some flowers of <i>Antirrhinum majus</i> two petal-like
+bodies standing up in front of, or opposite to the two petals of the
+upper lip,<a name="FNanchor_334_334" id="FNanchor_334_334"></a><a href="#Footnote_334_334" class="fnanchor">[334]</a> and similar developments in which each of the two
+adventitious segments are surmounted by an anther may be met with
+frequently. It does not follow because these organs bear anthers that
+they are morphologically true stamens. They are really scales, &amp;c.,
+taking on themselves accidentally the characters proper to stamens.</p>
+
+
+
+<p><span class='pagenum'><a name="Page_302" id="Page_302">[Pg 302]</a></span><b>Pistillody of the perianth.</b>&mdash;The passage of the segments of the
+perianth into carpels has been observed frequently in <i>Tulipa
+Gesneriana</i>, the change in question being generally attended by a
+partial virescence. M. Gay is said by Moquin to have observed a flower
+of <i>Crocus nudiflorus</i> in which the segments of the perianth were cleft
+and fringed at the same time, so that they presented the appearance of
+the stigmas.</p>

+
+<p><b>Pistillody of the sepals.</b>&mdash;In some double flowers of the garden pea
+communicated by Mr. Laxton, among other peculiarities was a
+supernumerary 5&ndash;6-leaved calyx, some of the segments of which were of a
+carpellary nature, and bore imperfect ovules on their margins, while at
+their extremities they were drawn out into styles.<a name="FNanchor_335_335" id="FNanchor_335_335"></a><a href="#Footnote_335_335" class="fnanchor">[335]</a></p>

+<p><b>Pistillody of the stamens.</b>&mdash;This change whereby the stamens assume
+more or less the appearance of pistils is more commonly met with than is
+the metamorphosis of the envelopes of the flower into carpels. In some
+cases the whole of the stamen appears to be changed, while in others it
+is the filament alone that is altered, the anther being deficient, or
+rudimentary; while, in a third class of cases, the filament is
+unaffected, and the anther undergoes the change in question. In those
+instances in which the filament appears to be the portion most
+implicated, it becomes dilated so as to resemble a leaf-sheath rather
+than a leaf-stalk, as it does usually.</p>
+
+<p>One of the most curious cases of this kind is that recorded in the
+'Botanical Magazine,' (tab. 5160, f. 4) as having occurred in <i>Begonia
+frigida</i> already alluded to, and in which, in the centre of a male
+flower, were four free ovoid ovaries alternating with as many stamens.
+In the normal flowers of this plant, as is well known, the male flowers
+have several stamens, while in the female flowers the ovary is strictly
+inferior, so that, in the singular flower just described, the perianth
+was inferior instead of being superior, as it is usually. It should be
+added also that the perianth in these malformed flowers was precisely
+like that which occurs ordinarily in the male flowers.</p>

+<p>In some varieties of the orange, called by the French "bigarades

+terminated by a glandular ring-like disc, is prolonged into a little
+stalk or gynophore, bearing a ring of supernumerary carpels. These
+carpels are isolated one<span class='pagenum'><a name="Page_304" id="Page_304">[Pg 304]</a></span> from another, and are formed by the

+
+<p>The additional carpels in the case of the apple of St. Val&eacute;ry, in which
+the petals are of a green colour, like the sepals, are by some
+attributed to the transformation of the stamens into carpels. These
+adventitious carpels frequently contain imperfect ovules and form a
+whorl above the normal ones. (See <i>Pyrus dioica</i> of Willdenow.)<a name="FNanchor_337_337" id="FNanchor_337_337"></a><a href="#Footnote_337_337" class="fnanchor">[337]</a> A

+changes the pistil of <i>Gentiana Amarella</i> bearing two sessile anthers.
+<i>Polemonium c&aelig;ruleum</i> is another plant very subject to this change.
+Brongniart<a name="FNanchor_340_340" id="FNanchor_340_340"></a><a href="#Footnote_340_340" class="fnanchor">[340]</a> describes a flower of this species in which the stamens
+were represented by a circle of carpels united to each other so as to
+form a sheath around the central ovary. By artificial fertilization M.
+Brongniart obtained fertile seeds from the central normal ovary as well
+as from the surrounding metamorphosed stamens.</p>
+
+<p><i>Cheiranthus Cheiri</i> has long been known as one of the plants most
+subject to this anomaly. De Candolle even mentions it in his 'Prodromus'
+as a distinct variety, under the name of <i>gynantherus</i>. Brongniart (loc.
+cit.) thus refers to the <i>Cheiranthus</i>:&mdash;"Sometimes these six carpellary
+leaves are perfectly free, and in this case they spread open, presenting
+two rows of ovules along their inner edges, or these edges maybe
+soldered together, forming a kind of follicle like that of the
+columbine; at other times, these staminal pistils are fused into two
+lateral bundles of three in each bundle, or into a single cylinder which
+encircles the true pistil. In a third set of cases these outer carpels
+are only four in number, two lateral and two antero-posterior, all fused
+in such a manner as to form around the normal pistil a prism-shaped
+sheath, with four sides presenting four parietal placent&aelig;, corresponding

+<p>In <i>Lilium tigrinum</i>, some specimens of which were gathered by Mr. J.
+Salter, in addition to various degrees of synanthy and other changes,
+some of the stamens were developed in the form of carpels, adherent by

+</div>
+
+<p>In <i>Saxifraga crassifolia</i> it sometimes happens that mixed with the
+stamens, and originating with them, are a number of distinct and
+perfectly formed carpels, wholly separated from the normal carpels, in
+the centre of the flower. In this particular instance there is usually
+no intermediate condition between the stamen and the pistil.
+Guillemin<a name="FNanchor_343_343" id="FNanchor_343_343"></a><a href="#Footnote_343_343" class="fnanchor">[343]</a> also describes a transformation of the stamens into
+carpels in <i>Euphorbia esula</i>.</p>
+
+<p>When the anther is involved it may be only partially so, or almost the
+whole organ may be transformed. As instances of very partial change may
+be cited the passage of the connective into a stigma in <i>Thalictrum
+minus</i>, or the passage of the points of the anthers into imperfect
+styles in some species of bamboo.<a name="FNanchor_344_344" id="FNanchor_344_344"></a><a href="#Footnote_344_344" class="fnanchor">[344]</a></p>
+
+<p>In <i>Rosa arvensis</i> similar transformations have been observed of a
+slightly more complex character than those just mentioned, and passing
+into more important changes, especially to the formation of pollen
+within ovules, formed on the edges of an open carpellodic anther (<a href="#Page_186">see p.
+186</a>).</p>
+
+<p>Mr. Berkeley has recorded an analogous case in a gourd in which the
+stamens bore numerous ovules (p. 200), and Baillon describes another
+gourd in which certain fleshy appendages surrounding the andr&oelig;cium
+were provided with ovules.<a name="FNanchor_345_345" id="FNanchor_345_345"></a><a href="#Footnote_345_345" class="fnanchor">[345]</a></p>
+
+<p><span class='pagenum'><a name="Page_308" id="Page_308">[Pg 308]</a></span>Payer, in his 'Organog&eacute;nie,' p. 38, mentions a stamen of <i>Dion&aelig;a</i>
+bearing not only an anther, but likewise an ovule.</p>
+
+<p><i>Sempervivum tectorum</i> and <i>S. montanum</i>, have long been noticed as
+being very prone to present this change. Mohl<a name="FNanchor_346_346" id="FNanchor_346_346"></a><a href="#Footnote_346_346" class="fnanchor">[346]</a> remarks that, in the
+transformation of the stamens to the pistil in the common houseleek, the
+filament of the stamen generally preserves its form, the anthers alone
+undergoing change. At other times, however, the transformation takes
+place at the same time, both in the filament and in the anther. When the
+stamens are numerous some of them remain in their normal state, while
+others, and especially the inner ones, undergo a change. Sometimes all
+the stamens are changed simultaneously, while at other times some of
+these organs may be found in which the anther is partially filled with
+ovules, and partially with pollen.</p>
+
+<p>In the accompanying figures (fig. 165, <i>a-h</i>) a series of intermediate
+stages is shown between the ordinary stamen of <i>Sempervivum tectorum</i>
+and the ordinary carpel, from which it will be seen that the filament is
+little, if at all, affected, and that in those cases where there is a
+combination of the attributes of the stamen and of the pistil in the
+same organ the pollen is formed in the upper or inner surface of the
+leaf-organ, while the ovules arise from the opposite surface from the
+free edge, (<i>b</i>, <i>c</i>, <i>d</i>, <i>e</i>, <i>f</i>, <i>g</i>).</p>
+
+<p>In a drawing made by the Rev. G. E. Smith of a malformed flower of
+<i>Primula acaulis</i>, and which the writer has had the opportunity of
+examining, the stamens are represented as detached from the corolla, and
+their anthers replaced by open carpels, with ovules arising, not only
+from their edges, but also from their surfaces, while the apex of the
+carpellary leaf was drawn out<span class='pagenum'><a name="Page_309" id="Page_309">[Pg 309]</a></span> into a long style, terminated by a

+the stamen corresponds to the stalk of the leaf, and the anther to the
+leaf-blade, yet there are some points on which uncertainty still rests.
+One of these is as to the sutures of the anther. Do these chinks through
+which the pollen escapes correspond (as would at first sight seem
+probable) to the margins of the antheral leaf, or do they answer to the
+lines that separate the two pollen-cavities on each half of the anther
+one from the other? Professor Oliver, 'Trans. Linn. Soc.,' vol. xxiii,
+1862, p. 423, in alluding to the views held by others on this subject,
+concludes, from an examination of some geranium flowers in which the
+stamens were more or less petaloid, that Bischoff's notion as to the
+sutures of the anther is correct, viz., that they are the equivalents of
+the septa of untransformed tissue between the pollen-sacs. Some double
+fuchsias ('Gard. Chron.,' 1863, p. 989) add confirmation to this
+opinion. In these flowers the petals were present as usual, but the
+stamens were more or less petaloid, the filaments were unchanged, but
+the anthers existed in the form of a petal-like cup from the centre of
+which projected two imperfect pollen-lobes (the other two lobes being
+petaloid). Now, in this case, the margins of the anther were coherent to
+form the cup, and the pollen was emitted along a line separating the
+polliniferous from the petaloid portion of the anther. This view is also
+borne out by the double-flowered <i>Arbutus Unedo</i>, and also by what
+occurs in some double violets, wherein the anther exists in the guise of
+a broad lancet-shaped expansion, from the surface of which project four
+plates (fig. 157), representing apparently the walls of the pollen-sacs,
+but destitute of pollen; the chink left between these plates corresponds
+thus to the suture of the normal anther.

+</div>
+
+<p>The inner or upper portion of the anther-leaf is that which is most
+intimately concerned in the formation of pollen; it comparatively rarely
+(query ever) happens that the back or lower surface of the antheral leaf
+is specially devoted to the formation of pollen. On the other hand, in
+cases like those of the common houseleek, where we meet with petaloid
+organs combining the attributes of anthers and of carpels, we find the
+inner layers devoted to the production of pollen, the outer to the
+formation of ovules.
+</p><p>
+That the pollen-lobes are not to be taken as halves of a staminal leaf,
+but rather as specialised portions of it, not necessarily occupying half
+its surface, is shown also in the case of double-flowered <i>Malvace&aelig;</i>, in
+which the stamens are frequently partly petal-like, partly divided into
+numerous separate filaments, each bearing a one-, or it may be even a
+two-lobed anther. This circumstance is confirmatory of the opinion held
+by Payer, Duchartre, Dickson, and other organogenists, as to the
+compound nature of the stamens in these plants. The stamens are here
+analogues not of a simple entire leaf, but of a lobed, digitate, or
+compound leaf, each subdivision bearing its separate anther. On this
+subject the reader may consult M. M&uuml;ller's paper on the anther of
+<i>Jatropha Pohliana</i>, <i>&amp;c.</i>, referred to at page 255.</p></div>

+
+HETEROMORPHY.</h3>
+
+
+<p>There are certain malformations that have little in common beyond this,
+that they cannot readily be allocated in either of the great groups
+proposed by writers on teratology. There are also deformities which,
+unlike the majority of deviations from the ordinary structure, are
+absolute and not relative. While the latter are due to an exaggeration,
+or to an imperfection of development, or, it may be, to a partial
+perversion in organization, the former differ from the normal standard,
+not merely in degree, but absolutely. This is often the case when
+disease or injury affects the plant; for instance, in the case of galls
+arising from insect-puncture the structure is rather a new growth
+altogether, than dependent on mere hypertrophy of the original tissues.
+These absolute deformities arising from the causes just mentioned belong
+rather to pathology than to teratology strictly so called; but, under
+the head of deformities, may be mentioned sundry deviations not
+elsewhere alluded to.</p>

+(see Enation). Sometimes these are developed in a tubular form, so as to
+form a series of little horn-like tubes, or shallow troughs, as in
+<i>Aristolochia sipho</i>. At other times the nerves or ribs of the leaf
+project beyond the blade, and bear at their extremities structures
+similar to those just described.</p>

+
+<p>In a variety of <i>Codi&aelig;um variegatum</i> a similar formation may be seen to
+a minor extent. Even the common <i>Scolopendrium vulgare</i> occasionally
+produces small pitchers of this character, as in the varieties named
+<i>perafero-corautum</i>, Moore, and <i>peraferum</i>, Woll.<a name="FNanchor_350_350" id="FNanchor_350_350"></a><a href="#Footnote_350_350" class="fnanchor">[350]</a></p>
+
+<p>In carnations leaves may sometimes be seen from both surfaces, from
+which project long, sharp-pointed tubular spurs at irregular intervals.
+A very singular illustration of this is figured by Trattinick,<a name="FNanchor_351_351" id="FNanchor_351_351"></a><a href="#Footnote_351_351" class="fnanchor">[351]</a>, in
+which the leaves, epicalyx, sepals, and petals, were all provided with
+tubular spurs.</p>
+
+<p>In <i>Cephalotus follicularis</i> rudimentary or imperfect pitchers may be
+frequently met with, in which the stalk of the leaf is tubular and bears
+at its extremity a very small rudimentary leaf-blade. It is not in all
+cases easy to trace the origin and true nature of the ascidium, as the
+venation is sometimes obscure. If there be a single well-marked midrib
+the probability is that the case is one of cohesion of the margins of
+the leaf; but if the veins are all of about equal size, and radiate from
+a common stalk, the pouch-like formation is probably due to dilatation
+and hollowing of the petiole. Again, when the result of a union of the
+margins of the leaf, the pitcher is generally less regular than when
+formed from the hollowed end of a leaf-stalk. Further information is
+especially needed as to the mode of development and formation of these
+tubular organs, so as to ascertain clearly when they are the result of a
+true cupping process, and when of cohesion of the margins of one or more
+leaves. (See Cohesion, p. 31. For bibliographical references consult
+also A. Braun, 'Flora v. Bot. Zeit.,' 1835, t. xviii, p. 41,
+<i>Aristolochia</i>.)</p>
+
+
+
+<p><b>Tubular formations in the flower.</b>&mdash;A similar formation of tubes happens
+in some double flowers; for instance, it is not infrequent in double
+flowers of <i>Primula sinensis</i>, in which tubular petal-like structures
+are<span class='pagenum'><a name="Page_315" id="Page_315">[Pg 315]</a></span> attached to the inner surface of the corolla; sometimes these
+petaloid tubes replace the stamens, while at other times they appear to
+have no relation to those organs. In the particular flowers now alluded
+to the tubular form seems due to a dilatation, and not to a cohesion of
+the margins. (See Cohesion, p. 23.) These tubular petals resemble in
+form and colour almost precisely the normal corolla in miniature, but
+are not surrounded by a calyx, nor do they contain stamens, while the
+less perfect forms show clearly their origin from a single tube-like
+organ.</p>

+
+<p>The formation of spurs or spur-like tubes in a quasi-regular manner has
+been spoken of under the head of Irregular Peloria, p. 228, but we
+occasionally meet with tubular processes which seem to occur in an
+irregular manner, and to have no reference to the symmetrical plan of
+the flower, and which are due probably to the same causes as those which
+induce hypertrophy. Such spurs have frequently been seen on the corolla
+of <i>Digitalis purpurea</i>, <i>Antirrhinum majus</i>,<a name="FNanchor_352_352" id="FNanchor_352_352"></a><a href="#Footnote_352_352" class="fnanchor">[352]</a> <i>Tulipa Gesneriana</i>,
+and occasionally on the sepals of<span class='pagenum'><a name="Page_316" id="Page_316">[Pg 316]</a></span> <i>Fuchsia</i>. They are very frequent in

+
+<p>Similar processes may sometimes be seen in the capsules of <i>Linaria
+vulgaris</i>, as also in the fruits of some of the Solanums, quite without
+reference to the arrangement of the carpels, so that their production
+seems to be purely irregular.</p>
+
+<p>Morren, as previously remarked, gave the name "Solenaidie" to tubular
+deformities affecting the stamens, a term which has not been generally
+adopted; the deformity in question is by no means of uncommon occurrence
+in some double or partially pelorised flowers, as <i>Antirrhinum</i>,
+<i>Linaria</i>, &amp;c. A similar formation of conical out-growths may frequently
+be met with in the fruits quite irrespectively of any disjunction of the
+carpels.</p>
+
+
+
+<p><b>Contortion.</b>&mdash;An irregular twisting or bending of the stem or branches is
+by no means of uncommon occurrence, the inducing causes being often some
+restriction to growth in certain directions, or the undue or
+disproportionate growth in one direction, as contrasted with that in
+another. Hence it may arise from insect-puncture, parasitic growth, or
+any obstacle to the natural development. Frequently it exists in
+conjunction with fasciation, the ends of the branches being curved round
+like a shepherd's crook, from the growth on one side being so much
+greater than on the other. Sometimes it is a mere exaggeration of a
+normal condition; thus, in what are termed flexuose stems the stem
+twists alternately to one side or another, frequently in association<span class='pagenum'><a name="Page_317" id="Page_317">[Pg 317]</a></span>
+with an oblique form of the leaf. This state is sometimes present to an
+extreme degree, as in some varieties of shrubs (<i>Crat&aelig;gus</i>, <i>Robinia</i>,
+&amp;c.) cultivated for their singularly tortuous branches.</p>

+Moquin-Tandon<a name="FNanchor_353_353" id="FNanchor_353_353"></a><a href="#Footnote_353_353" class="fnanchor">[353]</a> alludes to a case of this kind in a species of pine
+(<i>Pinus</i>), in which a branch ended in four unequal divisions, which were
+strongly curved from without inwards, then became united in pairs, these
+latter in their turn blending into a single mass.</p>
+
+<p>In the case of some beeches growing in the forest of Verzy, near Rheims,
+the trunks of the trees are contorted in every direction, and, at a
+height of from fifteen to twenty feet, a number of branches are also
+given off, also much contorted, and occasionally intergrafted, so that
+it seems as if a heavy weight had been placed on the trees and literally
+flattened them. Similar malformations may occasionally be met with in
+the branches of the oak, and commonly in the weeping ash.</p>
+
+<p>M. Fournier<a name="FNanchor_354_354" id="FNanchor_354_354"></a><a href="#Footnote_354_354" class="fnanchor">[354]</a> mentions the stems of <i>Ruscus aculeatus</i> rolled in a
+circle, others twisted spirally.</p>
+
+<p>The phenomenon is not confined to woody plants, but has been met with in
+chicory, in <i>Antirrhinum</i>, and other herbaceous species.</p>
+
+<p>It is very difficult in some cases to separate these instances of
+irregular torsion from those in which the twisting takes place in a more
+or less regular spiral direction. In the former case the fibres of the
+plant are only indirectly involved, but in the latter the fibres
+themselves are coiled spirally from right to left, or <i>vice vers&acirc;</i>
+(spiral torsion), while not unfrequently both conditions may be met with
+at the same time.</p>
+
+<p>The leaves also are subject to similar deformities, of which a notable
+illustration has been recorded in the case of the date palm, <i>Ph&oelig;nix
+dactylifera</i>, originally observed by Goethe, and figured and described
+by Jaeger;<a name="FNanchor_355_355" id="FNanchor_355_355"></a><a href="#Footnote_355_355" class="fnanchor">[355]</a> the leaves are folded and twisted in every direction, in
+consequence of the fibrous band or cord which surrounds the leaves, and
+which generally breaks<span class='pagenum'><a name="Page_319" id="Page_319">[Pg 319]</a></span> as the leaflets increase in size, remaining from
+some cause or other unbroken, and thus serving to restrain the growth.</p>
+
+<p>A similar irregularity of growth occurs, not unfrequently, in the case
+of crocus leaves, when in the course of their growth, as they push their
+way through the soil, their progress becomes checked either by a stone
+or even by frost.</p>
+
+
+
+<p><b>Spiral torsion.</b>&mdash;Growth in a spiral direction, and the arrangement of
+the various organs of the plant in a spiral manner, are among the most
+common of natural phenomena in plants.<a name="FNanchor_356_356" id="FNanchor_356_356"></a><a href="#Footnote_356_356" class="fnanchor">[356]</a> Fibres are coiled spirally
+in the minute vessels of flowering plants, and are not wholly wanting
+even among fungi. The leaf-organs are very generally spirally arranged;
+the leaf-stalks are often so twisted as to bring leaves on one plane
+which otherwise would occupy several. In the leaf itself we have a
+spiral twist taking place constantly in <i>Alstr&oelig;meria</i>, in <i>Avena</i>,
+and other plants. A similar tendency is manifested in the flower-stalks,
+as in <i>Cyclamen</i> and <i>Vallisneria</i>, and the whole inflorescence, as in
+<i>Spiranthes</i>. Even the bark and wood of trees is often disposed
+spirally. This is very noticeable in some firs, and in the bark of the
+sweet chestnut (<i>Castanea</i>), of <i>Thuja occidentalis</i>, and other trees.
+The knaurs or excrescences which are sometimes found on the roots or
+stems of trees afford other illustrations of this universal tendency.
+These bodies consist of a number of embryo buds, which, from some cause
+or other, are incapable of lengthening. On examination every rudimentary
+or undeveloped bud may be seen to be surrounded by densely crowded
+fibres arranged spirally.</p>
+
+<p>The axes of nearly all twining plants are themselves twisted, and
+twisted in a direction corresponding to the spontaneous revolving
+movement exhibited by these plants, as in the hop, the convolvulus,
+passion flower,<span class='pagenum'><a name="Page_320" id="Page_320">[Pg 320]</a></span> &amp;c., the degree of twisting being dependent to a great
+extent on the roughness of the surface around which the stem
+twines<a name="FNanchor_357_357" id="FNanchor_357_357"></a><a href="#Footnote_357_357" class="fnanchor">[357]</a>.</p>
+
+<p>Considered as an exceptional occurrence, it occurs frequently in certain
+plants, and, when it affects the stem or branches, necessarily causes
+some changes in the arrangement of the parts attached to them; thus,
+spiral torsion of the axial organs is generally accompanied by
+displacement of the leaves, whorled leaves becoming alternate, and
+opposite or whorled leaves becoming arranged on one side of the stem
+only. Frequently also this condition is associated with fasciation, or,
+at least, with a distended or dilated state. An illustration of this in
+<i>Asparagus</i> has been figured at p. 14.</p>
+
+<p>Very often the leaves are produced in a spiral line round the stem, as
+in a specimen of <i>Dracocephalum speciosum</i> described and figured by C.
+Morren. The leaves of this plant are naturally rectiserial and
+decussate, but, in the twisted stem the leaves were curviserial, and
+arranged according to the 5/13 plan. Now, referring to the ordinary
+notation of alternate leaves, we shall have the first leaf covered by
+the fifth, with two turns of the spiral; since decussate leaves result
+from two conjugate lines, the formula will be necessarily 2/5. The
+fraction 5/13 hence comes regularly into the 2/5 series (2/5, 3/8,
+5/13). Thus, the leaves in assuming a new phyllotaxy, take one quite
+analogous to the normal one.</p>
+
+<p>One of the most curious instances that have fallen under the writer's
+own observation occurred in the stem of <i>Dipsacus fullonum</i>. (See
+'Proceedings of<span class='pagenum'><a name="Page_321" id="Page_321">[Pg 321]</a></span> the Linnean Society,' March 6, 1855, vol. ii, p. 370).
+The stem was distended, and hollow, and twisted on itself; its fibres,
+moreover, were arranged in an oblique or spiral direction; the branches
+or leaf-stalks, which usually are arranged in an opposite and decussate
+manner, were, in this case, disposed in a linear series, one over the
+other, following the line of curvature of the stem. When the course of
+the fibres was traced from the base of one of the stalks, upward around
+the stem, a spiral was found to be completed at the base of the second
+stalk, above that which was made the starting point. Now, if opposite
+leaves depend on the shortened condition of the internode between the
+two leaves, then, in the teazel-stem just described, each turn of the
+spiral would represent a lengthened internode; and, if the fibres of
+this specimen could be untwisted, and made to assume the vertical
+direction, and, at the same time, the internodes were shortened, the
+result would be the opposition of the branches and the decussation of
+the pairs; this explanation is borne out by the similar twisting which
+takes place so frequently in the species of <i>Galium</i> and other
+<i>Rubiace&aelig;</i>.</p>

+<p>G. Franc<a name="FNanchor_358_358" id="FNanchor_358_358"></a><a href="#Footnote_358_358" class="fnanchor">[358]</a> was one of the first to notice this twisting in <i>Galium</i>,
+and M. Duchartre,<a name="FNanchor_359_359" id="FNanchor_359_359"></a><a href="#Footnote_359_359" class="fnanchor">[359]</a> in mentioning a similar instance, gives the
+following explanation of the appearance which will be found to apply to
+most of these cases. In the normal stem of <i>Galium Mollugo</i> the
+branches<span class='pagenum'><a name="Page_322" id="Page_322">[Pg 322]</a></span> are opposite in each verticil and crossed in the two
+successive ones. The stem is four-angled, each angle having a nerve.
+Each of these nerves, springing from the origin of a branch in one
+whorl, terminates in the interval which separates the point of origin of
+the two branches in the whorl next above it. In the deformed stem one of
+the nerves corresponds to the insertion of a branch, its neighbour is in
+the adjoining vacant space; hence it results that four nerves correspond
+to two branches and to two consecutive interspaces, and hence the
+analogy between a single normal internode provided with its two branches
+and its four nerves. What confirms this inference is that the nerve,
+which begins at the point of origin of a branch, after making one spiral
+turn round the stem, terminates in the interval that separates the two
+following branches, just as in a branch of the normal stem it ends in
+the upper whorl between the two next branches. The torsion, then, in
+this <i>Galium</i> caused the separation of the two opposite branches of the
+same verticil, and placed them one above another, and this being
+reproduced in all the whorls, all the branches come to be arranged on
+the same longitudinal line. The leaves are susceptible of the same
+explanation; they are inserted in groups of three or four in one arc
+round the origin of each branch. In the malformation each series or
+group of four leaves, with its central branch, is equivalent to half a
+whorl of the natural plant with its axillary branch. In other words, the
+malformation consists in a torsion of the stem, which separates each
+whorl into two distinct halves; these half-whorls, with their axillary
+branches, are placed on a single longitudinal series one above another.
+This case is quoted at some length, as it is an admirable example of a
+very common form of malformation in these plants.</p>
+
+<p>In some parts of Holland where madder is cultivated a similar
+deformation is particularly frequent. The leaves, however, are not
+always grouped in the way in which they were described by M. Duchartre,<span class='pagenum'><a name="Page_323" id="Page_323">[Pg 323]</a></span>
+but more commonly form a single continuous line; when arranged in
+leaf-whorls it generally happens that some of the leaves are turned
+downwards, while others are erect. It has been said that this condition
+occurs particularly frequently in plants growing in damp places. It is
+certainly true that spiral torsion of the stem is specially frequent in
+the species of <i>Equisetum</i>, most of which grow in such spots. In these
+plants either the whole of the upper part of the stem is thus twisted,
+or a portion only: thus Reinsch<a name="FNanchor_360_360" id="FNanchor_360_360"></a><a href="#Footnote_360_360" class="fnanchor">[360]</a> cites a case in <i>Equisetum
+Telmateia</i>, where the upper and lower portions of the stem were normal,
+while the intermediate portion was twisted spirally. In this instance
+the whorl next beneath the spiral had twenty-eight branchlets, and that
+immediately above it thirty. Along the course of the spire there were
+two hundred and three; dividing this latter number by the mean of<span class='pagenum'><a name="Page_324" id="Page_324">[Pg 324]</a></span> the
+two preceding, it was seen that the spire included the constituents of
+seven ordinary verticils.</p>

+<p><b>Spiral twisting of the leaf</b> is scarcely of so common occurrence as the
+corresponding condition in the stem. In <i>Alstr&oelig;meria</i> it occurs
+normally, as also in some grasses. In the variety <i>annularis</i> of <i>Salix
+babylonica</i> the leaf is constantly coiled round spirally. A similar
+contortion occurs in a variety of <i>Codi&aelig;um variegatum</i> lately introduced
+from the islands of the South Seas by Mr. J. G. Veitch.</p>
+
+<p>Fern fronds are occasionally found twisted in the same manner, <i>e.g.</i>
+<i>Scolopendrium vulgare</i> var. <i>spirale</i>.<a name="FNanchor_362_362" id="FNanchor_362_362"></a><a href="#Footnote_362_362" class="fnanchor">[362]</a></p>
+
+
+
+<p><b>Adventitious tendrils.</b>&mdash;Under ordinary circumstances tendrils may be
+described as modifications of the leaf, the stipule, the branch, or of
+the flower stalk, so that it is not a matter of surprise to find
+tendrils occasionally springing from the sepals or petals, as indeed
+happens normally in <i>Hodgsonia</i>, <i>Strophanthus</i>, <i>&amp;c.</i></p>
+
+<p>M. Decaisne<a name="FNanchor_363_363" id="FNanchor_363_363"></a><a href="#Footnote_363_363" class="fnanchor">[363]</a> found a flower of the melon in which one of the
+segments of the calyx was prolonged into a tendril, and Kirschleger
+records a similar instance in the cucumber, while Mr. Holland ('Science
+Gossip,' 1865, p. 105) mentions a case in which one of the prickles on
+the fruit of a cucumber had grown out into a tendril.</p>
+
+<p>In <i>Cob&aelig;a scandens</i> the foliar nature of the tendril is shown by the
+occasional presence of a small leaflet on one of the branches of the
+tendril, and a similar appearance may frequently be seen in
+<i>Eccremocarpus scaber</i>. On the other hand, in the vine, the axial nature
+of the tendril is revealed by the not infrequent presence of flowers or
+berries on them, as also in <i>Modecca</i> and some <i>Passiflorace&aelig;</i>. </p><p><span class='pagenum'><a name="Page_327" id="Page_327">[Pg 327]</a></span></p>
+
+<p>Darwin, speaking of the tendrils of <i>Bignonia capreolata</i>, says it is a
+highly remarkable fact that a leaf should be metamorphosed into a
+branched organ, which turns from the light, and which can, by its
+extremities, either crawl like a root into crevices, or seize hold of
+minute projecting points, these extremities subsequently forming
+cellular masses, which envelope by their growth the first fibres and
+secrete an adhesive cement.</p>
+
+
+
+<p><b>Interrupted growth.</b>&mdash;This term is here used in the same sense as in
+ordinary descriptive botany, as when an "interruptedly pinnate" leaf is
+spoken of. A similar alternation may be observed occasionally as a
+teratological occurrence, though it is not easy to account for it.</p>

+similar deformity in the case of an apple, the dilatation of the
+flower-stalk below the ordinary fruit producing an appearance as if
+there were two fruits one above another.</p>
+
+<p>In leaves this peculiar irregularity of development is more common.</p><p><span class='pagenum'><a name="Page_328" id="Page_328">[Pg 328]</a></span></p>
+
+<p>In some varieties of <i>Codi&aelig;um variegatum</i> the leaves resemble those of
+<i>Nepenthes</i>, as the basal portion is broad, and terminates in a
+projecting midrib destitute of cellular covering, and this again
+terminates in a small pouch or pitcher. Somewhat similar variations may
+be found in ferns, especially <i>Scolopendrium vulgare</i>.</p>
+
+<p>Instead of the pouch there is formed sometimes in the plant last
+mentioned a supplementary four-lobed lamina, the four lobes being in two
+different planes, and diverging from the midrib, so that the section
+would resemble [symbol: Sideways X], the point of intersection of the x
+representing the position of the midrib. This four-winged lamina is thus
+very similar to the four-winged filaments described and figured at p.
+289, and to the leaf-like anther of <i>Jatropha</i> described by M. M&uuml;ller,
+p. 255.</p>
+
+
+
+<p><b>Cornute leaves</b> (<i>Folia cornuta</i>).&mdash;The condition to which this term
+applies is that in which the midrib, after running for a certain
+distance, generally nearly to the point of the leaf, suddenly projects,
+often in a plane different from that of the leaf, and thus forms a small
+spine-like out-growth. Should this happen to be terminated by a second
+laminar portion, an interrupted leaf would be formed. In <i>Scolopendrium
+vulgare</i> and other ferns this condition has been noticed, as also in
+some of the varieties of <i>Codi&aelig;um variegatum</i> already referred to.</p>
+
+
+
+<p><b>Flattening.</b>&mdash;There are some plants whose stem or branches, instead of
+assuming the ordinary cylindrical form, are compressed or flattened;
+such are some species of <i>Epiphyllum</i>, <i>Coccoloba</i>, <i>Bauhinia</i>, &amp;c. The
+same thing occurs in the leaf-like branches of <i>Ruscus</i>, the
+flower-stalks of <i>Xylophylla</i>, <i>Phyllanthus</i>, <i>Pterisanthes</i>. Martins
+proposes to apply the word 'cladodium' to such expansions, just as the
+term phyllodium is applied to the similar dilatation of the leaf-stalks.
+If we exclude<span class='pagenum'><a name="Page_329" id="Page_329">[Pg 329]</a></span> instances of fasciation, <i>i.e.</i> where several branches
+are fused together and flattened, we must admit that this flattening
+does not occur very often as a teratological appearance.</p>
+
+<p>Mr. Rennie figures and describes a root of a tree which had become
+greatly flattened in its passage between the stones at the bottom of a
+stream, and had become, as it were, moulded to the stones with which it
+came into contact.<a name="FNanchor_364_364" id="FNanchor_364_364"></a><a href="#Footnote_364_364" class="fnanchor">[364]</a></p>
+
+<p>The spadix of <i>Arum</i>, as also of the cocoa-nut palm, has been observed
+flattened out, apparently without increase in the number of organs.</p>
+
+<p>When the blade of the leaf is suppressed it often happens that the stalk
+of the leaf is flattened, as it were, by compensation, and the petiole
+has then much the appearance of a flat ribbon (phyllode). This happens
+constantly in certain species of <i>Acacia</i>, <i>Oxalis</i>, &amp;c., and has been
+attributed, but doubtless erroneously, to the fusion of the leaflets in
+an early state of development and in the position of rest.<a name="FNanchor_365_365" id="FNanchor_365_365"></a><a href="#Footnote_365_365" class="fnanchor">[365]</a></p>
+
+<p>In some water plants, as <i>Sagittaria</i>, <i>Alisma</i>, <i>Potamogeton</i>, &amp;c., the
+leaf-stalks are apt to get flattened out into ribbon-like bodies; and
+Olivier has figured and described a <i>Cyclamen</i>, called by him <i>C.
+linearifolium</i>, in which, owing to the suppression of the lamina, the
+petiole had become dilated into a ribbon-like expansion&mdash;d&eacute;formation
+ruban&eacute;e of Moquin.</p>

+
+POLYMORPHY.</h4>
+
+
+<p>Usually the several organs of the same individual plant do not differ to
+any great extent one from another. One adult leaf has nearly the same
+appearance and<span class='pagenum'><a name="Page_330" id="Page_330">[Pg 330]</a></span> dimensions as another; one flower resembles very closely
+another flower of the same age and so on. Nevertheless it occasionally
+happens that there is a very considerable difference in form in the same
+organs, not only at different times, but it may also be at the same
+time. Descriptive botanists recognise this occurrence in the case of
+leaves, and apply the epithet heterophyllous to plants possessed of
+these variable foliar characters. In the case of the flower, where
+similar diversity of form occasionally exists, the term dimorphism is
+used.</p>
+
+<p>As these phenomena appear constantly in particular plants, they are
+hardly to be looked on, under such circumstances, as abnormal, but where
+they occur in plants not usually polymorphic, they may be considered as
+coming within the scope of teratology.</p>
+
+
+
+<p><b>Heterophylly.</b>&mdash;As a general rule, the leaves or leaf-organs in each
+portion of a plant, from the rhizome or underground axis, where it
+exists, to the carpellary leaf, have their own special configuration,
+subject only to slight variations, dependent upon age, conditions of
+growth, &amp;c. The cotyledons are very uniform in shape in each plant, and
+are scarcely ever subject to variation. The leaves near the base of the
+stem, the root-leaves as they are not unfrequently called, sometimes
+differ in form from the stem-leaves; these again differ from the bracts
+or leaves in proximity to the flower. The floral envelopes themselves,
+as well as the bud-scales, all have their own allotted form in
+particular plants, a form by which they may, in most cases, be readily
+recognised. Hence, then, in the majority of plants there is naturally
+very considerable difference in the form of the leaf-organs, according
+to the place they occupy and the functions they have to fulfil; but, in
+addition to this, it not unfrequently happens that the leaf-organs in
+the same portion of the stem are subject to great variation in form.
+This is the condition to which the term heterophylly properly applies.
+The variation in form is usually<span class='pagenum'><a name="Page_331" id="Page_331">[Pg 331]</a></span> dependent on a greater or less degree
+of lobing of the margin of the leaf; thus, in the yellow jasmine, almost
+every intermediate stage may be traced from an ovate entire leaf to one
+very deeply and irregularly stalked. <i>Broussonettia papyrifera</i>, and
+<i>Laurus Sassafras</i>, and the species of <i>Panax</i>, may be mentioned as
+presenting this condition. Sometimes in the last-named genus, as also in
+<i>Pteridophyllum</i>, every gradation between simple and compound leaves may
+be traced. The horse-radish (<i>Cochlearia Armoracia</i>) may also be
+instanced as a common illustration of polymorphism in<span class='pagenum'><a name="Page_332" id="Page_332">[Pg 332]</a></span> the leaves. In
+ferns it is likewise of frequent occurrence, markedly so in
+<i>Scolopendrium D'Urvillei</i>, in which plant every gradation from a simple
+oblong frond to an exceedingly divided one may be found springing from
+the same rhizome at the same time.</p>

+<p class="caption"> <span class="smcap">Fig.</span> 177.&mdash;<i>Syringa persica laciniata</i>, showing polymorphous leaves.</p>
+</div>
+
+<p>A similar protean state, but little less remarkable, occurs in many of
+our British ferns, notably in <i>Scolopendrium vulgare</i>, of which Mr.
+Moore enumerates no fewer than 155 varieties,<a name="FNanchor_366_366" id="FNanchor_366_366"></a><a href="#Footnote_366_366" class="fnanchor">[366]</a> many of the forms
+occurring on the same plant at the same time. Cultivators have availed
+themselves of this tendency to produce multiform foliage, not only for
+the purposes of decoration or curiosity, as in the many cut-leaved or
+crisped-leaved varieties, but also for more material uses, as, for
+instance, the many varieties of cabbages, of lettuces, &amp;c. Most of these
+variations are mentioned under the head of the particular morphological
+change of which they are illustrations.</p>
+
+<p>The effect of a change in the conditions of growth in producing
+diversity in the form of the leaf may be here alluded to. <i>Ficus
+stipulata</i>, a plant used to cover the walls of plant-stoves in this
+country, and growing naturally on walls in India, like ivy, produces
+leaves of very different form, size, and texture, when grown as a
+standard, from what it does when adhering to a wall. <i>Marcgraavia
+umbellata</i> furnishes another example of a similar nature, as indeed, to
+a less extent, does the common ivy.</p>
+
+<p>Allusion has been already made to the occasional persistence of forms in
+adult life, which are commonly confined to a young state, as in the case
+of some conifers which present on the same plant, at the same time, two
+different forms of leaves. Mention has also been made of the presence of
+adventitious buds on leaves and in other situations. The leaves that
+spring from these buds are usually of the same form as the other leaves
+of the plant, but now and then they differ. Of this a remarkable
+illustration is afforded by a fern,<span class='pagenum'><a name="Page_333" id="Page_333">[Pg 333]</a></span> <i>Pteris quadriaurita</i>, in which the
+fronds emerging from an adventitious bud are very different from the
+ordinary fronds.</p>

+
+
+
+<p><b>Dimorphism.</b>&mdash;This term, applied specially to the varied form which the
+flowers or some of their constituent elements assume on the same plant,
+is an analogous phenomenon to what has been above spoken of as
+heterophylly, and, like it, it cannot, except under special
+circumstances, be considered as of teratological importance. A few
+illustrative cases, however, may here be cited.</p>
+
+<p>Sir George Mackenzie describes a variety of the potato<a name="FNanchor_367_367" id="FNanchor_367_367"></a><a href="#Footnote_367_367" class="fnanchor">[367]</a> (<i>Solanum
+tuberosum</i>), which produces first double and sterile flowers, and
+subsequently single fertile ones; the other portions of the plant do not
+differ much. </p><p><span class='pagenum'><a name="Page_334" id="Page_334">[Pg 334]</a></span></p>
+
+<p><i>Stackhousia juncea</i>, according to Clarke, has mixed with its perfect
+flowers a number of apetalous blossoms destitute of anthers.<a name="FNanchor_368_368" id="FNanchor_368_368"></a><a href="#Footnote_368_368" class="fnanchor">[368]</a></p>
+
+<p>This peculiarity is well exemplified in the tribe <i>Gaudichaudie&aelig;</i> of the
+order <i>Malpighiace&aelig;</i>. A. de Jussieu, in his monograph, speaks of these
+flowers as being very small, green, destitute of petals, or nearly so,
+with a single, generally imperfect anther; the carpels also are more or
+less imperfect, but not sufficiently so to prevent some seeds from being
+formed. A similar production of imperfect flowers has been noticed in
+many other orders, <i>e.g.</i> <i>Violace&aelig;</i>, <i>Campanulace&aelig;</i>, &amp;c. In some cases
+these supplementary blossoms are more fertile and prolific in good seeds
+than are the normally constructed flowers. M. Durieu de Maisonneuve
+alludes to a case where flowers of this description are produced below
+the surface of the ground. The plant in question is <i>Scrophularia
+arguta</i>, and it appears that towards the end of the summer the lowest
+branches springing from the stem bend downwards, and penetrate the soil;
+the branches immediately above the lowest ones also bend downwards, but
+do not always enter the earth. These branches bear fertile flowers:
+those which are completely below the soil are completely destitute of
+petals; those which are on the surface have a four-lobed corolla whose
+divisions are nearly equal, like those of <i>Veronica</i>.<a name="FNanchor_369_369" id="FNanchor_369_369"></a><a href="#Footnote_369_369" class="fnanchor">[369]</a></p>
+
+<p>To Sprengel, and specially to Darwin, physiologists are indebted for the
+demonstration of the relation of di- and trimorphic flowers to
+fertilisation. In certain genera of orchids, such as <i>Catasetum</i>, &amp;c.,
+flowers of such different form are produced that botanists, without
+hesitation, considered them as belonging to different genera, until the
+fact of their occasional production on the same plant showed that they
+were not of even specific importance. It was reserved for Mr. Darwin to
+show experimentally that these very different flowers<span class='pagenum'><a name="Page_335" id="Page_335">[Pg 335]</a></span> are really sexual
+forms of one and the same species, ordinarily occurring on different
+plants, i.e. di&oelig;cious, but occasionally formed on the same spike. The
+same excellent observer has demonstrated that the di- and trimorphic
+forms of <i>Primula</i>, of <i>Linum</i>, <i>Lythrum</i>, and other plants&mdash;forms
+differing mainly in the relative length of the stamens and styles, are
+also connected with striking differences in the number of perfect seeds
+produced. The most perfect degree of fertility is obtained when the
+stigma of one form is fertilised by the pollen taken from stamens of a
+corresponding height. On the other hand, when the union is, as Mr.
+Darwin states, illegitimate, that is, when the pollen is taken from
+stamens not corresponding in length to the style, more or less complete
+sterility ensues in the progeny, sometimes even utter infertility, such
+as happens when two distinct species are crossed, so that, in point of
+fact, the offspring of these illegitimate unions correspond almost
+precisely to hybrids.<a name="FNanchor_370_370" id="FNanchor_370_370"></a><a href="#Footnote_370_370" class="fnanchor">[370]</a></p>
+
+<p>Mere variations of form arising from hybridisation or other causes
+hardly fall within the limits of this work, though it is quite
+impossible to say where variations end and malformations begin. There
+are, however, two or three cases cited by Mr. Darwin<a name="FNanchor_371_371" id="FNanchor_371_371"></a><a href="#Footnote_371_371" class="fnanchor">[371]</a> from Gallesio
+and Risso to which it is desirable to allude. Gallesio impregnated an
+orange with pollen from a lemon, and the fruit borne on the mother tree
+had a raised stripe of peel like that of a lemon both in colour and
+taste, but the pulp was like that of an orange, and included only
+imperfect seeds. Risso describes a variety of the common orange which
+produces "rounded-oval leaves, spotted with yellow, borne on petioles,
+with heart-shaped wings; when these leaves fall off they are succeeded
+by longer and narrower leaves, with undulated margins, of a pale green
+colour, embroidered with yellow, borne on foot-stalks without<span class='pagenum'><a name="Page_336" id="Page_336">[Pg 336]</a></span> wings.
+The fruit whilst young is pear-shaped, yellow, longitudinally striated
+and sweet; but, as it ripens, it becomes spherical, of a reddish-yellow,
+and bitter."</p>
+
+
+
+<p><b>Sports or bud variations.</b>&mdash;These curious departures from the normal form
+can only be mentioned incidentally in this place, as they pertain more
+to variation than to malformation.</p>
+
+<p>The occasional production of shoots bearing leaves, flowers, or fruits
+of a different character from those found on the normal plant, is a fact
+of which gardeners have largely availed themselves in the cultivation of
+new varieties. The productions in question have been attributed to
+various causes, such as cross-breeding, grafting, budding, dissociation
+of hybrid characters, or reversion to some ancestral form, all of which
+explanations may be true in certain cases, but none of them supply the
+clue to the reason why one particular branch should be so affected, and
+the rest not; or why the same plant, at the same time, as often happens
+in Pelargoniums, should produce two, three, or more "sports" of a
+different character.</p>
+
+<p>These bud variations may be perpetuated by grafts or by cuttings,
+sometimes even by seed. With reference to cuttings a curious
+circumstance has been observed, viz., that if taken from the lower part
+of the stem, near the root, the peculiarity is not transmitted, but the
+young plant reverts to the characters of the typical form (Carri&egrave;re).
+This circumstance, however, is not of universal occurrence.</p>
+
+<p>For further particulars on this interesting subject the reader is
+referred to Darwin's 'Variation of Animals and Plants,' i, p. 373, where

+ALTERATIONS OF COLOUR.<a name="FNanchor_372_372" id="FNanchor_372_372"></a><a href="#Footnote_372_372" class="fnanchor">[372]</a></h4>
+
+
+<p>Changes in the colour of the several organs of plants are more often
+either pathological or the result of variation than of malformation
+properly so called.</p>
+
+<p>Alterations in colour arise from a diminished or an increased amount of
+colouring matter, or from an unusual distribution of the solid or fluid
+matters on which the colour depends. The superposition of cells
+containing colouring material of different tints produces naturally a
+very different set of hues from those which are manifested when the
+colours are not blended. Referring the reader to the ordinary text-books
+on vegetable physiology and chemistry for details as to the nature and
+disposition of colouring materials in plants under natural
+circumstances, it will only be necessary to cite a few instances of
+deviation from the general colour of plants or their organs.</p>
+
+
+
+<p><b>Albinism.</b>&mdash;This change is due to the deficient formation of green
+colouring matter or chlorophyll, and is more a pathological condition
+than a deformity.</p>
+
+<p>It seems necessary to draw a distinction between this state and ordinary
+blanching or etiolation. In the former case chlorophyll seems never to
+be formed in the affected parts, even if they be exposed to light, while
+an etiolated organ, when placed under favorable circumstances, speedily
+assumes a green colour. In <i>Richardia &aelig;thiopica</i> one or more leaves
+become occasionally as white as the spathe is usually.</p><p><span class='pagenum'><a name="Page_338" id="Page_338">[Pg 338]</a></span></p>
+
+
+
+<p><b>Virescence.</b>&mdash;Engelmann<a name="FNanchor_373_373" id="FNanchor_373_373"></a><a href="#Footnote_373_373" class="fnanchor">[373]</a> pointed out that, so far as flowers were
+concerned, there are two ways in which they assume a green colour,
+either by a simple development of chlorophyll in place of the colouring
+matter proper to the flower, or by an actual development of leaf-like
+organs in the room of the petals&mdash;frondescence. Morren<a name="FNanchor_374_374" id="FNanchor_374_374"></a><a href="#Footnote_374_374" class="fnanchor">[374]</a> judiciously
+proposed to keep these two conditions separate, calling the one
+virescence, the other frondescence (<a href="#Page_241">see p. 241</a>).</p>
+
+<p>Many of the cases recorded as reversions of the parts of the flower to
+leaves are simply instances of virescence; indeed, it is not in all
+cases easy to distinguish between the two states. The examination of the
+arrangement of the veins is often of assistance in determining this
+point; for instance, if, under ordinary circumstances, the venation of
+the petal be such as is characteristic of the sheath of the leaf, while
+in the green-coloured flower of the same species the venation is more
+like that which belongs to the blade of the leaf, the inference would,
+of course, be that the green colour was due to frondescence or phyllody.</p>
+
+<p>The persistence or duration of petals is often increased when they are
+subject to this change; instead of falling off speedily they become
+persistent when so affected.</p>
+
+<p>Some flowers are more liable to virescence than others. The common
+honeysuckle, <i>Lonicera Periclymenum</i>, is one of these, and it is
+noticeable in this plant that the calyx remains unaffected&mdash;a
+circumstance which Morren says shows the distinctness of virescence from
+frondescence; for, in this instance, we have the most foliaceous portion
+of the flower remaining unchanged, while the corolla and other organs,
+usually less leaf-like in their nature, assume a green colour; but this
+may rather be attributed to the axial nature of the so-called adherent
+calyx. The stamens in these green-flowered honeysuckles are usually
+green also, but with<span class='pagenum'><a name="Page_339" id="Page_339">[Pg 339]</a></span> abortive anthers, and the pistil also is in a
+rudimentary condition. <i>Umbellifer&aelig;</i> are not unfrequently subject to
+this change, <i>e.g.</i>, <i>Torilis Anthriscus</i>, <i>Daucus Carota</i>, <i>Heracleum
+Sphondylium</i>, <i>Carum carui</i>, &amp;c. <i>Primulace&aelig;</i>, again, are frequently
+subject to virescence. Among <i>Composit&aelig;</i> the following species are
+recorded as having had green flowers&mdash;<i>Cirsium tricephalodes</i>, <i>Senecio
+vulgaris</i>, <i>Calendula officinalis</i>, <i>Pyrethrum Parthenium</i>, <i>Carduus
+crispus</i>, <i>Hypoch&aelig;ris radicata</i>, <i>Hieracium prealtum</i>, <i>Cirsium
+arvense</i>, <i>Coreopsis Drummondi</i>.<a name="FNanchor_375_375" id="FNanchor_375_375"></a><a href="#Footnote_375_375" class="fnanchor">[375]</a> In <i>Ranunculace&aelig;</i> virescence has
+been observed in <i>Delphinium elatum</i>, <i>crassicaule</i> and <i>Ajacis</i>,
+<i>Anemone hortensis</i> and <i>nemorosa</i>, <i>Aquilegia vulgaris</i>, <i>Ranunculus
+Philonotis</i>.</p>
+
+<p>Many of these cases, and others that might be cited, are probably
+instances of frondescence or phyllody (<a href="#Page_241">see p. 241</a>).</p>
+
+
+
+<p><b>Chromatism.</b>&mdash;This term is here intended to apply specially to those
+cases in which any organ of a plant assumes a colour approximating to
+that of the petals, or in which the normal green is replaced by tints of
+some other colour. To a certain extent the change in question is the
+same as that spoken of under the head of petalody (<a href="#Page_283">see p. 283</a>), but
+there are cases in which, while the ordinary situation and form are
+those of leaves, the coloration is that of the petals. Such was the case
+in the <i>Gesnera</i> mentioned by Morren (<a href="#Page_88">see p. 88</a>), and in which a leaf
+occupied the position of an inflorescence, and became brightly coloured.
+In tulips the presence of a highly coloured leaf on the flower-stalk,
+below the flower, is not uncommon. So also the bracts or leaves below
+the perianth in <i>Anemone coronaria</i> and <i>hortensis</i> not unfrequently
+assume the coloration usually confined to the parts of the perianth. A
+similar illustration has presented itself, as this sheet is passing
+through the press, in which two of the leaflets of the compound leaf of
+a rose were brightly coloured like<span class='pagenum'><a name="Page_340" id="Page_340">[Pg 340]</a></span> the petals, the others being of
+their ordinary green colour.</p>
+
+<p>The occurrence of coloured bracts, as in <i>Poinsettia</i>, <i>Bougainvillea</i>,
+&amp;c., is very common under natural conditions, and need not here be
+further alluded to.</p>
+
+<p>Increased intensity of colour often accompanies teratological changes;
+an instance has just been alluded to in the <i>Gesnera</i>; the feather
+hyacinth, <i>Muscari comosum</i>, furnishes another illustration, the
+adventitious pedicels being brightly coloured.</p>
+
+<p>In fasciated stems, also, of herbaceous plants, it not unfrequently
+happens that the upper portions of the stem are brightly coloured.</p>
+
+<p>The occurrence of flowers or fruits of different colours on the same
+plant, or even in the same cluster, is a phenomenon which does not come
+within the scope of the present book; the reader may, however, be
+referred to the excellent summary on this subject published by Mr.
+Darwin in his work on the 'Variation of Animals and Plants under
+Domestication.'</p>

+<h2><a name="BOOK_III" id="BOOK_III"></a>BOOK III.<br />
+
+DEVIATIONS FROM THE ORDINARY NUMBER OF ORGANS.</h2>
+
+
+<p>To a certain extent the number of the organs of a plant is of even
+greater consequence for purposes of classification than either their
+form or their arrangement; for instance, the number of cotyledons in the
+embryo is made the chief basis of separation between the two great
+groups of flowering plants, the monocotyledons and the dicotyledons. In
+the one group, moreover, the parts of the flower are arranged in groups
+or whorls of five; in the other the arrangement is ternary. In mosses
+the teeth of the peristome are arranged in fours, or in some multiple of
+that number. So far as the larger groups are concerned, and also in
+cases where the actual number of parts is small, the numerical relations
+above described are very constant; on the other hand, in the minor
+subdivisions, and especially where the absolute number of parts is
+large, considerable variation may occur, so that descriptive botanists
+frequently make use of the term indefinite, and apply it to cases where
+the number of parts is large and variable, or, at any rate, not easy to
+be estimated.</p>
+
+
+
+<p>Considered teratologically, the changes, as regards the number of
+organs, are readily grouped into those<span class='pagenum'><a name="Page_342" id="Page_342">[Pg 342]</a></span> consequent on a decreased and
+into those resulting from an increased development. The alteration may
+be absolute or relative. There may be an actual deficiency in the number
+of parts or an increase in their number, but in either case the change
+may be simply a restoration of the primitive number, a species of
+peloria, in fact. An increased number of parts, moreover, may depend not
+so much on the formation of additional parts as on the subdivision of
+one.</p>
+
+<p>It seems also desirable to treat separately those cases in which there
+is an increased number of buds either leaf-buds or flower-buds, as the
+case may be, as happens in what is termed prolification. This formation
+of buds occurring, as it does, often in unwonted situations is treated
+of under the head of alterations of arrangement, the mere increase in
+number being considered of subordinate importance as contrasted with the
+altered disposition (<a href="#Page_100">see p. 100</a>).</p>
+
+
+
+
+<p><span class='pagenum'><a name="Page_343" id="Page_343">[Pg 343]</a></span></p>
+<h3><a name="PART_Ic" id="PART_Ic"></a>PART 1.<br />
+
+INCREASED NUMBER OF ORGANS.</h3>
+
+
+<p>An augmentation in the number of parts may arise from several causes,
+and may sometimes be more apparent than real. True multiplication exists
+simply as a result of over-development; the affected organs are repeated
+sometimes over and over again each in their proper relative position,
+and without any transmutation of form.</p>
+
+<p>Metamorphy, on the other hand, often gives rise to the impression that
+parts are increased in number, when it may be that the stamens and
+pistils, one or both, are not so much increased in number as altered in
+appearance. The double anemones and ranunculus of gardens, amongst many
+other analogous illustrations, may be mentioned. In these flowers, owing
+to the petalody of the stamens and pistils, one or both, an impression
+of exaggerated number is produced, which is by no means necessarily a
+true one. Fission or lateral subdivision also gives rise to an apparent
+increase in number; thus, some so-called double flowers, the elements of
+which appeared to be increased in numbers, owe the appearance merely to
+the laciniation or subdivision of their petals.</p>
+
+<p>The French botanists, following Dunal and Moquin, attribute an increase
+in the number of whorls in the corolla, and other parts of the flower,
+to a process which they call chorisis, and they consider the
+augmentation to be due to the splitting of one petal, for instance, into
+several;&mdash;somewhat in the same manner as one may separate successive
+layers of talc one from the other.</p><p><span class='pagenum'><a name="Page_344" id="Page_344">[Pg 344]</a></span></p>
+
+<p>English botanists, on the other hand, have been slow to admit any such
+process, because, in most instances, no alteration in the law of
+alternation takes place in these double flowers, and in those few cases
+where the law is apparently infringed, the deviation is explained by the
+probable suppression of parts, which were they present would restore the
+natural arrangement of the flower; and, that this is no imaginary or
+purely theoretical explanation, is shown by some of the <i>Primulace&aelig;</i>,
+wherein a second row of stamens is occasionally present in the adult
+condition, and renders the floral symmetry perfect.</p>
+
+<p>The double daffodil, where there are from forty to fifty petaloid organs
+instead of fifteen, and wherein each piece exhibits a more or less
+perfect coronal lobe at the junction of the claw and the limb, has been
+cited as an objection to chorisis, though it is difficult to see on what
+grounds.</p>
+
+<p>In <i>Delphinium</i>, as shown by Braun,<a name="FNanchor_376_376" id="FNanchor_376_376"></a><a href="#Footnote_376_376" class="fnanchor">[376]</a> the stamens and carpels are
+members of a continuous spiral series, and in the double balsam an extra
+corolline whorl is produced, without the suppression of the stamens, in
+the following manner: the ordinary stamens are replaced by petals, the
+carpels by stamens, while an additional whorl of carpels is produced at
+the summit of the axis. In this instance, therefore, the doubling is
+distinctly referrible to an absolute increase in the number of whorls,
+and not to chorisis.<a name="FNanchor_377_377" id="FNanchor_377_377"></a><a href="#Footnote_377_377" class="fnanchor">[377]</a></p>
+
+<p>On the other hand, it must be admitted that there are many cases which
+are not to be explained in any other way than that suggested by the
+French botanists before alluded to. Probably, the main difficulty in the
+way of accepting the doctrine of chorisis is the unfortunate selection
+of the word used to designate the process; this naturally suggests a
+splitting of an organ already perfectly formed into two or more
+portions, either in the same plane as the original organs,<span class='pagenum'><a name="Page_345" id="Page_345">[Pg 345]</a></span> "parallel
+chorisis;" or at right angles to it "collateral chorisis." Indeed,
+before so much attention had been paid to the way in which the floral
+organs are developed, it was thought that an actual splitting and
+dilamination did really take place; Dunal and Moquin both assert as
+much. The truth would rather seem to be that, in the so-called parallel
+chorisis at least, the process is one of hypertrophy and
+over-development rather than of splitting. The adventitious petal or
+scale is an excrescence or an outgrowth from the primary organ, and
+formed subsequently to it.</p>
+
+<p>In the case of "compound stamens" the original stamens are first
+developed each from its own cellular "mamelon," or growing point; and,
+after a time, other secondary growing points emerge from the primary
+one, and in this way the stamens are increased in number, without
+reference, necessarily, to the so-called law of alternation. Outgrowths
+from leaves, multiplying the laminar surface, are alluded to under the
+head of hypertrophy, and it is probable that some of the cases of
+duplication of the flower, or of the formation of adventitious segments
+outside the ordinary corolla as alluded to in succeeding paragraphs (see
+Pleiotaxy of the corolla), are due to a similar process.<a name="FNanchor_378_378" id="FNanchor_378_378"></a><a href="#Footnote_378_378" class="fnanchor">[378]</a></p>
+
+<p>The formation of parts in unwonted numbers may be merely a reversion to
+what is supposed to have been the original form, and in this way there
+may be a restoration of parts that are usually undeveloped or
+suppressed. There can be little or no doubt that there are in reality
+six stamens in <i>Orchidace&aelig;</i>, of which one only, under ordinary
+circumstances, is developed. When the numerical symmetry is restored, as
+it sometimes is, it is obvious that the augmentation that occurs is of a
+different character from that arising from<span class='pagenum'><a name="Page_346" id="Page_346">[Pg 346]</a></span> a repetition or renewed
+development of organs. When the increased number arises from
+multiplication proper, or from repetition, the ordinary laws of
+alternation are not interfered with, but if from chorisis or
+"d&eacute;doublement," it may happen that the normal arrangement is disturbed.</p>
+
+<p>Without studying the mode of development, it is not in all cases
+possible to tell under which of the above categories any particular
+instance should be placed; hence, in the following sections, except
+where otherwise stated, the cases are grouped according to the
+appearance presented in the adult condition, rather than to the way in
+which the changes from the typical condition are brought about. With
+reference to the foliar organs it is necessary to distinguish those
+cases in which there is, from any cause, an augmentation in the number
+of component parts of a whorl, from those in which the increase takes
+place in the numbers of the whorls themselves.</p>

+
+
+<p>By Linn&eacute; an undue number of branches was designated as "plica," from the
+analogy with the disease of the hair known as plica polonica: "<i>Plicata
+dicitur planta, cum arbor vel ramus excrescit minimis intertextis
+ramulis, tanquam plica polonica ex pilis, ceu instar nidi Pic&aelig;, quod
+vulgo a genio ortum arbitratur; frequens apud nos in Betula, pr&aelig;sertim

+
+<p>By some of the older authors this condition was called polyclady. In
+some cases, it would seem to<span class='pagenum'><a name="Page_347" id="Page_347">[Pg 347]</a></span> be due to fungi as in the witches' brooms
+(hexenbesen) of the German forests; in other instances, it is a result
+of mutilation as after the operation of pollarding.</p>
+
+<p>Moquin-Tandon<a name="FNanchor_380_380" id="FNanchor_380_380"></a><a href="#Footnote_380_380" class="fnanchor">[380]</a> mentions a case in a grafted ash in the botanic
+garden of Toulouse, where below the graft there was a large swelling,
+from which proceeded more than a thousand densely-packed, interlacing
+branches.</p>
+
+<p>This must have been similar to the condition so commonly met with in the
+birch, and frequently in the hornbeam and the thorn, and which has
+prompted so many a schoolboy to climb the tree in quest of the apparent
+nest. It is probable that some of the large "gnaurs" or "burrs," met
+with in elms, &amp;c., also in certain varieties of apples, are clusters of
+adventitious buds, some of which might, and sometimes do, lengthen out
+into branches.</p>
+
+<p>An increased number of branches also necessarily arises when the
+flower-buds are replaced by leaf-buds.</p>

+cannot, in all cases, be determined. Certainly,<span class='pagenum'><a name="Page_349" id="Page_349">[Pg 349]</a></span> in some cases examined
+by me the latter was the case.<a name="FNanchor_384_384" id="FNanchor_384_384"></a><a href="#Footnote_384_384" class="fnanchor">[384]</a></p>
+
+<p>Under this head, too, may be included those cases wherein an ordinarily
+spicate inflorescence becomes paniculate owing to the branching of the
+axis and the formation of an unwonted number of secondary buds.
+Instances of this kind may be met with in willows, hazels, alders, and
+other amentaceous plants. In the case of the hazel the unusual
+development of male catkins sometimes coincides with an alteration in
+their position, instead of being placed near the axil of a leaf; they
+become terminal. Jaeger figures and describes a bunch of <i>Pinus
+sylvestris</i> bearing in one case seventy minute cones, and in another
+fifty-nine. These cones preserved the same spiral arrangement among
+themselves which is proper to the leaves. These latter, indeed, replaced
+the strobili above.<a name="FNanchor_385_385" id="FNanchor_385_385"></a><a href="#Footnote_385_385" class="fnanchor">[385]</a></p>

+
+<p>M. Reichardt describes an analogous case in the same species, and
+attributes the inordinate number of cones to a fungus (<i>Peridermium
+pini</i>). In this case<span class='pagenum'><a name="Page_350" id="Page_350">[Pg 350]</a></span> there were no less than 227 cones, but each one

+
+<p>Of a similar character is the many-headed pineapple. Among grasses such
+a branching of the inflorescence is exceedingly common,&mdash;which is the
+more readily understood as the normal inflorescence is in so many cases
+paniculate. Cultivators have, in some instances, availed themselves of
+this peculiarity, as in the Egyptian wheat or corn of abundance
+(<i>Triticum compositum</i>), certain varieties of Maize, etc. Similar
+exuberant growths occur in <i>Orchidace&aelig;</i>, in <i>Cyperace&aelig;</i>, e.g. <i>Carex</i>,
+in <i>Restiace&aelig;</i>, and indeed they may be found in any plant with a similar
+form of inflorescence. In all these cases the branching begins at the
+lower part of the spike, and extends from below upwards in an indefinite
+manner, even although the primary inflorescence be definite.</p>
+
+<p>Among the <i>Equisetace&aelig;</i> a similar plurality of spikes occurs often as a
+result of mutilation.<a name="FNanchor_387_387" id="FNanchor_387_387"></a><a href="#Footnote_387_387" class="fnanchor">[387]</a> The deviation in question might in some
+instances be turned to good account, as in the <i>Triticum</i> before
+mentioned or as in the broccoli shown at fig. 182, though it must be
+added that the apparent advantages are often counterpoised by some
+undesirable qualities or by some circumstance which prevents us availing
+ourselves of the new condition.</p>
+
+
+
+<p><b>Multiplication of Bulbs.</b>&mdash;This occurrence has been briefly alluded to
+previously (<a href="#Page_84">see p. 84</a>). The most curious cases are those in which one
+bulb is placed on the top of another as happened in some bulbs of
+<i>Leucoium &aelig;stivum</i> described by M. Gay.<a name="FNanchor_388_388" id="FNanchor_388_388"></a><a href="#Footnote_388_388" class="fnanchor">[388]</a> Irmisch described a similar
+phenomenon in <i>L. vernum</i>; and Mr. Moggridge has communicated drawings
+of a similar formation in the same species grown in the neighbourhood of
+Mentone. </p><p><span class='pagenum'><a name="Page_351" id="Page_351">[Pg 351]</a></span></p>
+
+<p>From the instances cited it is clear that branching of the inflorescence
+occurs most frequently in those plants naturally characterised by a
+dense compact mode of growth, whether that be definite or indefinite, as
+in spikes, umbels, capitula, &amp;c.; so that compound spikes, umbels, &amp;c.,
+are formed in the place of simple ones (see also prolification of the
+inflorescence, <a href="#Page_102">p. 102</a>).</p>

+some of the cases where the axile organs, branches, &amp;c., appear to be
+multiplied, the increased number is due to subdivision rather than to
+renewed formation (see Fission). Of this last description is an instance
+which came under the writer's notice after the section relating to that
+subject was in print, and which may therefore here be alluded to. The
+instance is that of the subdivision of the leaf-like organs of
+<i>Sciadopitys verticillata</i>. In one instance the pseudo leaf divided, and
+from the division proceeded a little axis, bearing at its summit a
+verticil of pseudo leaves. This division and formation of new axes and
+verticils affords ample confirmation of the opinion thrown out by
+Professor Alexander Dickson, that the apparent leaves of this plant were
+really branches: see 'Revue Horticole,' 1867, and 'Report. Bot.

+<h4><a name="CHAPTER_IIh" id="CHAPTER_IIh"></a>CHAPTER II.<br />
+
+MULTIPLICATION OF FOLIAR ORGANS.</h4>
+
+
+<p>The cases referrible to this head may be ranged under two sections
+according as the increase is due to plurality of ordinarily single
+organs, or to an increase in the number of verticils or whorls.</p>
+
+<p>When, in place of a single leaf organ two or more are really or in
+appearance present the occurrence may be due to one of several causes;
+among them may be mentioned an actual formation of parts in unwonted
+number, hypertrophy or enation, chorisis or fission, disjunction,
+adhesion of one leaf to another or to the stem, as in some of the leaves
+called "geminate," wherein the two leaves, though apparently in
+juxtaposition, yet originate from different parts of the stem, but by
+coalescence or lack of separation produce the impression as if they
+sprang from the same node. In the adult state it is not always possible
+to ascertain with certainty to which of these causes the increase in the
+number of leaves is due, though a clue to the real state of things may
+be gained from attention to the distribution of the veins, to the
+arrangement or phyllotaxy of the leaves, the size and position of the
+supernumerary organs, &amp;c.</p>
+
+<p>The term "phyllomania," as ordinarily used, is applied to an unwonted
+development of leafy tissue, as in some begonias where the scales or
+ramenta are replaced by small leaflets, or as in some cabbage leaves,
+from the<span class='pagenum'><a name="Page_353" id="Page_353">[Pg 353]</a></span> surface of which project, at right angles to the primary
+plane, other secondary leafy plates; but these are, strictly speaking,
+cases of hypertrophy (see Hypertrophy).</p>
+
+<p>Those instances in which the actual number of leaves is increased, so
+that in place of one there are more leaflets, may be included under the
+term "pleiophylly," which may serve to designate both the appearance of
+two or more leaves in the place usually occupied by a single one, and
+also those normally compound leaves in which the number of leaflets is
+greater than usual.</p>
+
+<p>The increased number of leaves in a whorl may well be designated as
+"polyphylly," using the word in the same sense as in ordinary
+descriptive botany, while "pleiotaxy" may be applied to those cases in
+which the number of whorls is increased.</p>

+</div>
+
+
+
+<p><b>Pleiophylly.</b>&mdash;As above stated, this term is proposed to designate those
+cases in which there is an absolute increase in the number of leaves
+starting from one particular point, as well as those in which the number
+of leaflets in a compound leaf is preternaturally increased. The
+simplest cases are such as are figured in the adjacent cuts, wherein, in
+place of a single leaf, two are produced in the elm. In the one case the
+new leaflet springs from the apex of the petiole and partially fills<span class='pagenum'><a name="Page_354" id="Page_354">[Pg 354]</a></span>
+the space consequent on the obliquity of the base of the leaf. In the
+other it would seem as if two distinct leaves emerged from the stem in
+juxtaposition. This is probably due to a lateral chorisis or subdivision
+of the primitive tubercle or growing point, followed by a like
+subdivision of the vascular bundle supplying it. There are certain
+varieties of elm that very generally present this anomaly on their rank,
+coarse, growing shoots. In these cases the new growths have the same
+direction as the primary one, but in other cases the supplementary
+production is exactly reversed in direction. Thus, in the common hazel
+(<i>Corylus</i>) a second smaller leaf proceeding from the end of the
+leaf-stalk at the base of the primary one may frequently be seen. M.
+Germain de Saint Pierre records an instance in a mulberry leaf, from the
+base of which proceeded a large leafy expansion divided into two<span class='pagenum'><a name="Page_355" id="Page_355">[Pg 355]</a></span>
+tubular, horn-like projections, and in the centre a thread-like process
+representing the midrib and terminated by a small two-lipped limb.<a name="FNanchor_392_392" id="FNanchor_392_392"></a><a href="#Footnote_392_392" class="fnanchor">[392]</a>
+Dr. Ferdinand M&uuml;ller speaks of a leaf of <i>Pomaderris elliptica</i> as
+bearing a secondary leaf on its under surface.<a name="FNanchor_393_393" id="FNanchor_393_393"></a><a href="#Footnote_393_393" class="fnanchor">[393]</a></p>

+</div>
+
+<p>The leaves of <i>Heterocentron macrodon</i> have likewise been observed
+occasionally to produce leaflets from their upper surface.</p>
+
+<p>To this production of leaves from leaves the late Professor Morren
+applied the term "autophyllogeny."<a name="FNanchor_394_394" id="FNanchor_394_394"></a><a href="#Footnote_394_394" class="fnanchor">[394]</a> The Belgian botanist figures a
+small perfect leaf springing from the nerves of the upper surface of the
+primary leaf in a species of <i>Miconia</i>. As in the hazel, the direction
+of the adventitious leaf is inversely that of the primary one, the upper
+surface of the supernumerary leaflet being turned towards the
+corresponding surface of the normal leaf. A similar occurrence took
+place in <i>Gesnera zebrina</i>, but the new growth in this case sprang from
+the lower face of the leaf. Morren explains the appearances in question
+by supposing that the supplementary leaf is one of a pair belonging to a
+bud borne on a slender stalk. This stalk and one of the bud-leaves are
+supposed to be inseparably united<span class='pagenum'><a name="Page_356" id="Page_356">[Pg 356]</a></span> with the primary leaf. But there is
+no reason at all for supposing the existence of adhesion in these cases;
+no trace of any such union is to be seen. A much more natural
+explanation is that, from some cause or another, development at the apex
+of the petiole or on the surface of the nerves, instead of taking place
+in one plane only, as usual, takes place in more than one, thus showing
+the close relationship, if not the intrinsic identity, between the
+leaf-stalk and its continuation, the midrib, with the branch and its
+subdivisions. The form of the leaf-stalk and the arrangement of the
+vascular bundles in a circle in the case of the hazel, before alluded
+to, bear out this notion. Such cases are significant in reference to the
+notion propounded by M. Casimir de Candolle, that the leaf is the
+equivalent of a branch in which the upper portion of the vascular circle
+is abortive.<a name="FNanchor_395_395" id="FNanchor_395_395"></a><a href="#Footnote_395_395" class="fnanchor">[395]</a></p>
+
+<p>Compound leaves, as has been stated, occasionally produce an extra
+number of leaflets; one of the most familiar illustrations of this is in
+the case of the four-leaved shamrock (<i>Trifolium repens</i>), which was
+gathered at night-time during the full moon by sorceresses, who mixed it
+with vervain and other ingredients, while young girls in search of a
+token of perfect happiness made quest of the plant by day. Linn&eacute;, who in
+this matter, at any rate, had less than his usual feeling for romance,
+says of the four-leaved trefoil that it differs no more from the
+ordinary trefoil than a man with six fingers differs from one provided
+with the ordinary number. It should be stated that five and six
+adventitious leaflets are found almost as frequently as four.</p>
+
+<p>Walpers describes a case where the leaf of <i>T. repens</i> bore seven
+leaflets. Schlechtendal alludes to a similar increase in number in
+<i>Cytisus Laburnum</i>, and many other instances might be cited.</p>

+
+<p>Frondiferous leaves have much the appearance of branches provided with
+leaves, and they may be compared with those instances in which an
+adventitious bud is placed on the surface or edges of the leaves, as in
+<i>Gesnera</i>, <i>Cardamine</i>, &amp;c. In truth, the two conditions merge one into
+the other, as in some begonias, where the ramenta often become leaf-like
+and bear small bulbils in the axil.</p>
+
+<p>When frondiferous leaves die the appendages die also, but when a true
+bud has been formed on a leaf it does not of necessity die with the leaf
+that bears it, but separates from it and continues to grow
+independently.</p>
+
+
+
+<p><b>Increased number of stipules, spathes, &amp;c.</b>&mdash;Seringe relates the
+occasional presence of two or three additional stipules upon the
+leaf-stalks of <i>Salix fragilis</i>, and even makes a variety (<i>Salix
+pendula</i>, var. <i>multistipulata</i>).</p>
+
+<p>An increase in the number of the spathes has been often noticed in
+Arads<a name="FNanchor_396_396" id="FNanchor_396_396"></a><a href="#Footnote_396_396" class="fnanchor">[396]</a>. Prof. Alex. Braun has studied this subject in some
+detail<a name="FNanchor_397_397" id="FNanchor_397_397"></a><a href="#Footnote_397_397" class="fnanchor">[397]</a>. In <i>Calla palustris</i> the shoot which continues the growth
+of the plant proceeds from the axil of the last leaf but one; the very
+last leaf producing no bud, but if accidentally a shoot is developed in
+this latter situation it produces flowers at once. No leaves are formed,
+but, on the contrary, two or three spathes surround the spadix, so that
+the presence of an increased number of spathes in this plant is
+associated with the development of a side shoot from the axil of the
+last leaf, the situation whence, under natural circumstances, no shoot
+at all issues. The supernumerary spathes are not always on the same
+level, but may be separated by a considerable interval. They vary very
+much in size, and sometimes assume the form and appearance of leaves.
+Similar anomalies<span class='pagenum'><a name="Page_358" id="Page_358">[Pg 358]</a></span> occur in other Arads as <i>Arum maculatum</i>, <i>Richardia
+&aelig;thiopica</i>, and <i>Anthurium Scherzerianum</i>, frequently combined with a
+leaf-like appearance of the spathes and sometimes with a subdivision of
+the spadix into two or three branches.</p>
+
+<p>Engelmann relates the occurrence of an increased number of glumes in
+<i>Bromus velutinus</i> associated with suppression of the flowers.</p>
+
+
+
+<p><b>Polyphylly.</b>&mdash;As previously explained, this term is here applied to those
+cases in which the members of any particular whorl are increased in
+number, the whorls themselves not necessarily being augmented.</p>
+
+<p>The simplest cases of this kind are those in which we meet with an
+unusual number of leaves in a whorl.</p>
+
+
+
+<p><b>Increased number of leaves in a whorl.</b>&mdash;This may arise from actual
+multiplication, or from lateral chorisis, or fission. The true nature of
+the case may usually be ascertained by an examination of the
+distribution of the veins of the leaves, or of the fibrous cords of the
+stem, by the relative position of the supernumerary organs, &amp;c.</p>
+
+<p>Among plants with normally opposite leaves the following occasionally
+produce them in whorls of three:&mdash;<i>Lonicera brachypoda</i>, <i>L. Xylosteum</i>,
+<i>Weigela rosea</i>, <i>Cornus mas</i>, <i>Vinca minor</i>, &amp;c.</p>
+
+<p><i>Paris quadrifolia</i> may frequently be met with five leaves in its whorl,
+or even six.<a name="FNanchor_398_398" id="FNanchor_398_398"></a><a href="#Footnote_398_398" class="fnanchor">[398]</a></p>
+
+
+
+<p><b>Increased number of bracts.</b>&mdash;This is not of infrequent occurrence; one
+of the most curious instances is that recorded by Mr. Edwards<a name="FNanchor_399_399" id="FNanchor_399_399"></a><a href="#Footnote_399_399" class="fnanchor">[399]</a> in
+<i>Cerastium glomeratum</i>, where, in place of the usual pair of bracts at
+the base of the head of flowers, there was a whorl of six or eight,
+forming an involucre. The flowers in this case were apetalous and
+imperfect.</p>
+
+
+
+<p><b>Polyphylly of the calyx.</b>&mdash;This may occur without any<span class='pagenum'><a name="Page_359" id="Page_359">[Pg 359]</a></span> other perceptible
+change, while at other times the number of the other parts of the flower
+is proportionately increased. In a flower of a plum six sepals in place
+of five sometimes exist; a precisely similar occurrence in the flowers
+of the elder (<i>Sambucus</i>), the <i>Fuchsia</i>, and of <i>&OElig;nanthe crocata</i>,
+may occasionally be met with. In the latter case, indeed, there are
+sometimes as many as ten segments to the calyx, and this without the
+other parts of the flower being correspondingly augmented. Among
+monocotyledons a similar increase is not uncommon, as in <i>Tulipa</i>,
+<i>Allium</i>, <i>Iris</i>, <i>Narcissus</i>, &amp;c.</p>
+
+<p>In some plants there seems to exist normally much variation in the
+number of parts; thus in some species of <i>Lacistema</i> in adjacent flowers
+the calyx may be found with four, five, or six segments.</p>
+
+<p>Most of these cases of polyphylly affecting the calyx may be explained
+by lateral chorisis or fission.</p>
+
+
+
+<p><b>Polyphylly of the corolla.</b>&mdash;This may happen in connection with similar
+alterations in the calyx and stamens, or sometimes as an isolated
+occurrence. In the latter case it may be due to lateral chorisis, to
+substitution, or to the development of organs usually suppressed; thus,
+when in aconites we meet with four or five horn-like nectaries (petals)
+instead of two only, as usual, the supernumerary ones are accounted for
+by the inordinate development of parts which ordinarily are in an
+abortive or rudimentary state only. This is borne out by what happens in
+<i>Balsamine&aelig;</i>. In the common garden balsam the fifth petal is
+occasionally present, while in <i>Hydrocera triflora</i> this petal is always
+present.</p>
+
+<p>In a flower of a <i>Cyclamen</i> recently examined there were ten petals in
+one series, the additional five being evidently due to the subdivision
+of the five primary ones; the natural circular plan of the flower was
+here replaced by an elliptical one. A similar occurrence takes place in
+the flowers of maples (<i>Acer</i>), which sometimes show an increased number
+of parts in their<span class='pagenum'><a name="Page_360" id="Page_360">[Pg 360]</a></span> floral whorls and an elliptical outline. Whether the
+additional organs in this last case are the result of complete lateral
+chorisis or of multiplication proper I do not know.</p>
+
+<p>Orchids are very subject to an increase in the number of their labella.
+As illustrations may be cited an instance recorded by Mr. J. T.
+Moggridge in a flower of <i>Ophrys insectifera</i>, and in which there were
+two labella without any other visible deviation from the ordinary
+conformation.<a name="FNanchor_400_400" id="FNanchor_400_400"></a><a href="#Footnote_400_400" class="fnanchor">[400]</a></p>
+
+<p>I am indebted to Mr. Hemsley for the communication of a similar specimen
+in <i>O. apifera</i>, in which there were two divergent lips, each with the
+same peculiar markings. One of the sepals in this flower was adherent to
+one of the lateral petals. This augmentation of the labella depends
+sometimes on the separation, one from the other, of the elements of
+which the lip is composed, at other times on the development, in the
+guise of lips, of stamens which are usually suppressed (<a href="#Page_380">see p. 380</a>).</p>
+
+<p>The following enumeration will suffice to show the genera in which an
+increased number of petals or perianth-segments in any given whorl most

+
+<p><b>Polyphylly of the andr&oelig;cium.</b>&mdash;An increased number of stamens
+frequently accompanies the corresponding alterations in other whorls,
+and seems, if anything, to be more frequent among monocotyledonous
+plants than among dicotyledonous ones; thus, we occasionally find
+tetramerous flowers in <i>Crocus</i>, <i>Hyacinthus</i>, <i>Tulipa</i>, <i>Iris</i>,
+<i>Tigridia</i>, &amp;c., and more rarely in <i>Yucca</i> (<i>Y. flexilis</i><a name="FNanchor_401_401" id="FNanchor_401_401"></a><a href="#Footnote_401_401" class="fnanchor">[401]</a>).</p>
+
+<p>The increased number of stamens in a single whorl may result from a
+development of organs usually suppressed, and constitute a form of
+regular peloria as in <i>Linaria</i>, wherein a fifth stamen is occasionally
+met with. Among normally didynamous plants such numerical restitution,
+so to speak, is not unusual; thus, in <i>Veronica</i> four and five stamens
+occur. Fresenius has seen five stamens in <i>Lamium</i>, <i>Mentha</i>,
+<i>Chelone</i>;<a name="FNanchor_402_402" id="FNanchor_402_402"></a><a href="#Footnote_402_402" class="fnanchor">[402]</a> Bentham in <i>Melittis</i>, and other instances are cited
+under the head of peloria. Chorisis may also serve to account for some
+of these cases; thus, Eichler<a name="FNanchor_403_403" id="FNanchor_403_403"></a><a href="#Footnote_403_403" class="fnanchor">[403]</a> figures a flower of <i>Matthiola annua</i>
+with five long stamens instead of four; one of the long pairs of stamens
+has here undergone a greater degree of repetition than usual. De
+Candolle<a name="FNanchor_404_404" id="FNanchor_404_404"></a><a href="#Footnote_404_404" class="fnanchor">[404]</a> cites and figures a curious form of <i>Capsella
+Bursa-pastoris</i> sent him by Jacquin, and which was to some extent
+reproduced by seed. In the flowers of this variety there were no petals,
+but ten stamens; hence De Candolle inferred that the petals were here
+replaced by stamens, but Moquin<a name="FNanchor_405_405" id="FNanchor_405_405"></a><a href="#Footnote_405_405" class="fnanchor">[405]</a> objects, and with justice, to this
+view, as the ten stamens are all on the same line; he considers the
+additional stamens to be the result of chorisis. Buchenau<a name="FNanchor_406_406" id="FNanchor_406_406"></a><a href="#Footnote_406_406" class="fnanchor">[406]</a> mentions
+the presence<span class='pagenum'><a name="Page_362" id="Page_362">[Pg 362]</a></span> of seven stamens in another Crucifer, <i>Ionopsidium
+acaule</i>. Here the supernumerary organ was placed between two of the long
+stamens. The effect of chorisis in producing an augmentation of parts is
+well seen in some plants that have some of their flowers provided with
+staminodes or abortive stamens, and others with clusters or phalanges of
+perfect stamens. Thus, in the female flowers of <i>Liquidambar</i> there are
+five small staminodes without anthers, whereas in the male flower the
+stamens are numerous and grouped together in phalanges, so that the
+relation of simple to compound stamens is in this case readily seen, as
+also in many <i>Malvace&aelig;</i>, <i>Sterculiace&aelig;</i>, <i>Byttneriace&aelig;</i>, <i>Tiliace&aelig;</i>, and
+<i>Myrtace&aelig;</i>. It is probably the idea of splitting or dilamination
+involved in the word chorisis that has led many English botanists to
+hesitate about accepting the notion. Had they looked upon the process as
+identical with that by which a branched inflorescence replaces an
+unbranched one, or a compound leaf takes the place of a simple one, the
+objections would not have been raised with such force. The process
+consists, in most cases, not so much in actual cleavage of a
+pre-existing organ as in the development of new-growing points from the
+old ones.</p>
+
+<p>An illustration given by Moquin from Dunal<a name="FNanchor_407_407" id="FNanchor_407_407"></a><a href="#Footnote_407_407" class="fnanchor">[407]</a> goes far to support the
+notion here adopted. The majority of the stamens of laurels (<i>Laurus</i>)
+have, says M. Dunal, on each side of the base of their filaments a small
+glandular bifid appendage; these excrescences are liable to be changed
+into small stamens. The male flowers have a four-leaved calyx, and
+sometimes eight stamens, each with two glands, four in one row, opposite
+to the sepals, four in a second series alternating with the first. More
+generally two of the stamens are destitute of glands, but have in their
+place a perfectly developed stamen, so that in these latter flowers
+there are twelve stamens. </p><p><span class='pagenum'><a name="Page_363" id="Page_363">[Pg 363]</a></span></p>
+
+<p>M. Clos<a name="FNanchor_408_408" id="FNanchor_408_408"></a><a href="#Footnote_408_408" class="fnanchor">[408]</a> mentions a flower of rue (<i>Ruta</i>) wherein there were two
+stamens joined together below and placed in front of a petal, as in
+<i>Peganum</i>.</p>
+
+<p>Buchenau<a name="FNanchor_409_409" id="FNanchor_409_409"></a><a href="#Footnote_409_409" class="fnanchor">[409]</a> mentions a flower of <i>Lotus uliginosus</i> in which there
+were eleven stamens, namely, two free and nine monadelphous; and
+Hildebrand describes an analogous increase in a flower of <i>Sarothamnus
+scoparius</i> in which, in conjunction with a seven-toothed calyx, there
+were two carinas and fourteen stamens. It would seem probable in this
+case that there was a coalescence of two flowers at an early date and
+consequent suppression of some of the parts of the flower. Whether this
+was the case or not in this particular illustration, it is nevertheless
+certain that many of the recorded instances of increased number in the
+organs of a flower are really the results of a fusion of two or more
+flowers, though frequently in the adult state but few traces of the
+coalescence are to be seen.</p>
+
+
+
+<p><b>Polyphylly of the gyn&oelig;cium.</b>&mdash;Moquin<a name="FNanchor_410_410" id="FNanchor_410_410"></a><a href="#Footnote_410_410" class="fnanchor">[410]</a> remarks that, as the pistils
+are, generally speaking, more or less subject to pressure, owing to
+their central position, and it may be added owing to their later
+development, than the other parts of the flower, they are more subject
+to suppression than to multiplication; nevertheless, augmentation in the
+number of carpels does occasionally take place, especially when the
+other parts of the flower are also augmented in number. Sometimes this
+increase in the number of carpels is due to pure multiplication, without
+any other change. At other times the increase is due to a substitution
+of stamens or other organs for carpels (see Substitutions). In other
+cases the augmentation seems to be due to the development of parts
+usually suppressed; for instance, in <i>Antirrhinum</i>, where there are
+usually only two carpels<span class='pagenum'><a name="Page_364" id="Page_364">[Pg 364]</a></span> present, but where, under peculiar
+circumstances, five may be found&mdash;thus rendering the symmetry
+complete.<a name="FNanchor_411_411" id="FNanchor_411_411"></a><a href="#Footnote_411_411" class="fnanchor">[411]</a> In <i>Papilionace&aelig;</i>, wherein usually only one carpel is
+developed, we occasionally find two, or even more, as in <i>Wistaria</i>,
+<i>Gleditschia</i>, <i>Trifolium</i>, &amp;c. In <i>Prunus</i> and <i>Amygdalus</i> from two to
+five carpels are occasionally to be found,<a name="FNanchor_412_412" id="FNanchor_412_412"></a><a href="#Footnote_412_412" class="fnanchor">[412]</a> in <i>Mimosa</i> five, in
+<i>Umbellifer&aelig;</i> three to five; in some composites, <i>e.g.</i> <i>Spilanthes</i>,
+five carpels have also been noticed; in <i>Crucifer&aelig;</i> three and four, in
+grasses three.<a name="FNanchor_413_413" id="FNanchor_413_413"></a><a href="#Footnote_413_413" class="fnanchor">[413]</a> The double cocoa-nut affords an illustration of the
+development of two carpels out of three, one only generally arriving at
+perfection. Triple nuts (<i>Corylus</i>) also owe their peculiarity to the
+equal development of all three carpels which exist in the original
+flower, but of which, under ordinary circumstances, two become abortive.
+It is necessary, however, to distinguish these cases from those in which
+two embryos are developed in one seed.</p>
+
+<p>The following list may serve to show in what genera this change has been
+most frequently noticed, and it may be said in general terms that
+<i>Crucifer&aelig;</i>, <i>Umbellifer&aelig;</i>, and <i>Liliace&aelig;</i>, are the orders most
+frequently affected. Cases of peloria are not included in the subjoined

+<p><b>Polyphylly of the flower in general.</b>&mdash;Although, for the sake of
+convenience, multiplication has here been treated of as it affects the
+members of individual whorls of the flower, yet it must be remembered
+that, in general, the augmentation is not confined to one whorl, but
+affects several; thus, if the sepals are increased, the<span class='pagenum'><a name="Page_366" id="Page_366">[Pg 366]</a></span> petals are
+likely to be so likewise, and so forth. One of the most curious

+wherein there was an increased number of sepals, a corresponding
+augmentation in the petals, while the pistil was composed of two and

+
+<p><b>Increased number of ovules or seeds.</b>&mdash;This appears not to be of very
+frequent occurrence, at least in those plants where the number of these
+organs is normally small; where, as in <i>Primula</i>, the ovules and seeds
+are produced in large quantities, it is not practicable to ascertain
+whether the number be augmented or not in any particular case. Very
+probably, the attachment or source of origin of the ovules determines,
+in some measure, their number. Thus, in the case of marginal
+placentation the number must be limited by the narrow space from which
+they proceed, whereas in parietal and free central placentation the
+ovules are generally numerous. In the latter case, however, it will be
+remembered that solitary ovules are not rare. An increased number of
+ovules is generally remarked in conjunction with some other change, such
+as a foliaceous<span class='pagenum'><a name="Page_368" id="Page_368">[Pg 368]</a></span> condition of the carpel, in which the margins are
+disunited. In such cases the ovules may occupy the margin or may be
+placed a short distance within it, as in the case of some open carpels
+of <i>Ranunculus Ficaria</i>,<a name="FNanchor_417_417" id="FNanchor_417_417"></a><a href="#Footnote_417_417" class="fnanchor">[417]</a> and in which two ovules were borne in
+shallow depressions on the upper or inner surface of the open carpel and
+supplied with vascular cords from the central bundle or midrib. The
+outer coating of the ovule here contained barred or spiral fusiform
+vessels derived from the source just indicated.</p>
+
+<p>In the very common cases where the pistil of <i>Trifolium repens</i> becomes
+foliaceous (see Frondescence), the outer ovules are generally two or
+more instead of being solitary. So, also, in the Rose with polliniferous
+ovules (<a href="#Page_274">see p. 274</a>). Among <i>Umbellifer&aelig;</i> affected with frondescence of
+the pistil a similar increase in the number of ovules takes place. It
+will be borne in mind that in most, if not all, these cases the
+structure of the ovule is itself imperfect.<a name="FNanchor_418_418" id="FNanchor_418_418"></a><a href="#Footnote_418_418" class="fnanchor">[418]</a></p>
+
+<p>What are called in popular parlance double almonds or double nuts
+(<i>Corylus</i>) are cases where two seeds are developed in place of one.</p>
+
+<p>In the 'Revue Horticole,' 1867, p. 382, mention is made of a bush which
+produces these double nuts each year&mdash;in fact, it never produces any
+single-seeded fruit. The plant was a chance seedling, perhaps itself the
+offspring of a double-seeded parent. It would be interesting to observe
+if the character be retained by the original plant, and whether it can
+be perpetuated by seed or by grafting.</p>
+
+<p>It is necessary to distinguish in the case of the nut between additional
+seeds or ovules, as just described, and the double, triple, or fourfold
+nuts that are occasionally met with, and which are the result either of
+actual multiplication of the carpels or of the continued development of
+some of the carpels which, under ordinary<span class='pagenum'><a name="Page_369" id="Page_369">[Pg 369]</a></span> circumstances cease to grow
+(<a href="#Page_364">see <i>ante</i>, p. 364</a>). In the case of a ripe nut with two seeds it might
+be impossible to tell whether the adventitious seed were the product of
+multiplication, or whether it belonged, in the first instance, to the
+same carpel as that producing the fellow-seed, or to a different and now
+obliterated ovary. In all probability, however, the second seed would be
+accounted for by the development of two seeds in one carpellary cavity.</p>
+
+<p>There is still another condition occasionally met with in the almond,
+and which must be discriminated from the more common multiplication of
+the seed, and which is the multiplication of the embryos within the
+seed, and which furnishes the subject of the succeeding paragraph.</p>
+
+
+
+<p><b>Increased number of embryos.</b>&mdash;A ripe seed usually contains but a single
+embryo, although in the ovular state preparation is commonly made for
+more; and, indeed, in certain natural orders plurality of embryos in the
+same seed does occur, as in <i>Cycade&aelig;</i> and <i>Conifer&aelig;</i>. In the seeds of
+the orange (<i>Citrus</i>), in those of some <i>Euphorbiace&aelig;</i>, &amp;c., there are
+frequently two or more additional embryos. A similar occurrence has been
+recorded in the mango, for a specimen of which I am indebted to the Rev.
+Mr. Parish, of Moulmein.<a name="FNanchor_419_419" id="FNanchor_419_419"></a><a href="#Footnote_419_419" class="fnanchor">[419]</a></p>

+
+<p><b>Increased number of the cotyledons.</b>&mdash;Although the presence of one or of
+two cotyledons in the embryo is generally accepted as a valuable means
+of separating flowering plants into two primary groups, yet, like all
+other means of discrimination, it occasionally fails, and, indeed,
+almost always requires to be taken in conjunction with some other
+character. There are cases among flowering plants where the embryo is
+homogeneous in its structure, there are others in which the number of
+the cotyledons is more than two. Thus, in some seeds of <i>Cola acuminata</i>
+the cotyledons vary in number from two to five. I have not been able to
+ascertain precisely whether this multiplication of the cotyledons is
+characteristic of all the seeds of particular trees, or whether some
+only are thus affected. Some fruits that I examined bore out the latter
+view, as in the same pod were seeds with two, three, and four cotyledons
+respectively.</p>
+
+<p>I have also seen three cotyledons present in embryo-plants of <i>Correa</i>,
+<i>Crat&aelig;gus Oxyacantha</i>, <i>Dianthus sinensis</i>, <i>Daucus Carota</i>, <i>Cerasus
+Lauro-cerasus</i>. De Candolle alludes to a case of the kind in the bean,
+and figures a species of <i>Solanum</i> with three cotyledons.<a name="FNanchor_420_420" id="FNanchor_420_420"></a><a href="#Footnote_420_420" class="fnanchor">[420]</a> Jaeger
+alludes to a similar instance in <i>Apium Petroselinum</i>;<a name="FNanchor_421_421" id="FNanchor_421_421"></a><a href="#Footnote_421_421" class="fnanchor">[421]</a> Ehrenberg to
+one in the marigold (<i>Calendula</i>);<a name="FNanchor_422_422" id="FNanchor_422_422"></a><a href="#Footnote_422_422" class="fnanchor">[422]</a> Reinsch to an analogous
+appearance in the beech (<i>Fagus</i>), associated with a union of the
+margins of two out of the three cotyledons, and of those of two out of
+the three leaves next adjacent.<a name="FNanchor_423_423" id="FNanchor_423_423"></a><a href="#Footnote_423_423" class="fnanchor">[423]</a> This fusion seems frequently to
+accompany increase in the number of cotyledons. It was so in the
+<i>Correa</i>, and in the <i>Crat&aelig;gus</i> previously mentioned. Some of these
+cases may be accounted for by chorisis or by a cleavage of the original
+cotyledons, as happens, according to Duchartre,<a name="FNanchor_424_424" id="FNanchor_424_424"></a><a href="#Footnote_424_424" class="fnanchor">[424]</a> in some<span class='pagenum'><a name="Page_371" id="Page_371">[Pg 371]</a></span> Conifer&aelig;,
+which he considers to be improperly termed polycotyledonous. Whether
+this holds good in the Loranths, where (<i>Nuytsia</i>, <i>Psittacanthus</i>) an
+appearance of polycotyledony exists, is not stated. In the case of the
+rue (<i>Ruta</i>) figured by M. A. de Jussieu<a name="FNanchor_425_425" id="FNanchor_425_425"></a><a href="#Footnote_425_425" class="fnanchor">[425]</a> this splitting of one
+cotyledon into two is sufficiently evident, as is also the case in the
+sycamore (<i>Acer pseudo-platanus</i>), seedlings of which may often be met
+with divided cotyledons.</p>
+
+<p>In other instances a fusion of two embryo plants may give rise to a
+similar appearance, as in the <i>Euphorbia</i> and <i>Sinapis</i> found by M.
+Alph. de Candolle (<a href="#Page_56">see <i>ante</i>, p. 56</a>).</p>
+
+
+
+<p><b>Pleiotaxy or multiplication of whorls.</b>&mdash;In the preceding section notice
+has been taken of the increased number of parts in a single whorl, but
+an augmentation of the number of distinct whorls is still more
+frequently met with. Many of the so-called double flowers owe their
+peculiarity to this condition. The distinction between the two modes in
+which the parts of the flower are increased in number has been pointed
+out by Engelmann, Moquin, and others, and the two seem to require
+distinctive epithets; hence the application of the terms polyphylly and
+pleiotaxy, as here proposed.</p>
+
+
+
+<p><b>Pleiotaxy in the bracts.</b>&mdash;An increase in the number of bracts has been
+met with very constantly in a species of <i>M&aelig;sa</i>, and in a peculiar
+variety of carnation, called the wheat-ear carnation.<a name="FNanchor_426_426" id="FNanchor_426_426"></a><a href="#Footnote_426_426" class="fnanchor">[426]</a> In some of
+these cases the increase in the number of bracts is attended by a
+corresponding suppression in the other parts of the flower. Such a
+condition has been frequently met with in <i>Gentiana Amarella</i>, where the
+bracts are increased in<span class='pagenum'><a name="Page_372" id="Page_372">[Pg 372]</a></span> number, coloured purple, and destitute of any
+true floral organs. A similar condition exists in some varieties of
+<i>Plantago major</i> (var. <i>paniculata</i>), as has been previously stated, p.
+109.</p>

+Lortet<a name="FNanchor_427_427" id="FNanchor_427_427"></a><a href="#Footnote_427_427" class="fnanchor">[427]</a> records a case of the kind in <i>Erica multiflora</i>, the

+usual, and were covered for their whole length with small rose-coloured
+bracts arranged in irregular whorls, the upper ones sometimes enclosing
+imperfect flowers. In the 'Gardeners' Chronicle,' 1865, p. 769, is
+figured a corresponding instance of <i>Delphinium Consolida</i>, in which the
+bracts were greatly increased in number, petaloid, and, at the same
+time, the central organs of the flower were wholly wanting.</p>

+Irmish<a name="FNanchor_429_429" id="FNanchor_429_429"></a><a href="#Footnote_429_429" class="fnanchor">[429]</a> records an analogous case in <i>Anemone Hepatica</i>, wherein the
+involucre was doubled. Similar augmentation occurs in cultivated
+Anemone. In addition to the plants already mentioned, Engelmann<a name="FNanchor_430_430" id="FNanchor_430_430"></a><a href="#Footnote_430_430" class="fnanchor">[430]</a>
+mentions as having produced bracts in unwonted numbers, <i>Lythrum
+Salicaria</i>, <i>Plantago major</i>, <i>Veronica spicata</i>, <i>Echium vulgare</i>,
+<i>Melilotus arvensis</i>, and <i>Rubus fruticosus</i>.</p>
+
+<p>It must here be remarked that this great number of the bracts occurs
+naturally in such plants as <i>Godoya</i>, in which the bracts, or, as some
+consider them, the segments of the calyx, are very numerous, and
+arranged in several overlapping segments.</p>
+
+<p>In some of the cultivated double varieties of <i>Nigella</i> the finely
+divided involucral bracts are repeated over and over again, but on a
+diminished scale, to the exclusion of all the other parts of the flower.</p>
+
+
+
+<p><b>Pleiotaxy or repetition of the calyx.</b>&mdash;The true calyx is very seldom
+affected in this manner, unless such organs as the epicalyx of mallows,
+<i>Potentilla</i>, &amp;c., be considered as really parts of the calyx.</p>
+
+<p>In <i>Linaria vulgaris</i> R&oelig;per observed a calyx consisting of a double
+series, each of five sepals, in conjunction with other changes.<a name="FNanchor_431_431" id="FNanchor_431_431"></a><a href="#Footnote_431_431" class="fnanchor">[431]</a> It
+is also common in double columbines, delphiniums, nigellas, &amp;c.</p>
+
+<p>In the 'Revue Horticole,' 1867, p. 71, fig. 9, is described and figured
+by M. B. Verlot a curious variety of vine grown for years in the Botanic
+Garden at Grenoble, under the name of the double-flowered vine. The
+place of the flower is occupied by a large number of successive whorls
+of sepals disposed in regular order, and without any trace of the other
+portions of the flower. It is, in fact, more like a leaf-bud than a<span class='pagenum'><a name="Page_375" id="Page_375">[Pg 375]</a></span>
+flower. The outermost whorls of this flower open at the time when the
+ordinary flowers of vines do; the second series are gradually produced,
+and expand about the time when the ovaries of the normal flowers begin
+to swell; a third series then gradually forms, and so on, until frost
+puts a stop to the growth. This malformation, it appears, is produced
+annually in certain varieties of vine, and may be perpetuated by
+cuttings.</p>
+
+<p>The flower of the St. Val&egrave;ry apple, already alluded to under the head of
+sepalody, might equally well be placed here. It is not very material
+whether the second whorl of organs be regarded as a repetition of the
+calyx or as a row of petals in the guise of sepals.</p>
+
+<p>Engelmann<a name="FNanchor_432_432" id="FNanchor_432_432"></a><a href="#Footnote_432_432" class="fnanchor">[432]</a> cites the following plants as occasionally presenting a
+repetition of the calyx, in most cases with a suppression of the other
+floral whorls:&mdash;<i>Stachys lanata</i>, <i>Myosotis palustris</i>, <i>Veronica
+media</i>, <i>Aquilegia vulgaris</i>, <i>Nigella damascena</i>, <i>Campanula
+rapunculoides</i>.</p>
+
+
+
+<p><b>Pleiotaxy in the perianth.</b>&mdash;Increase in the number of whorls in the
+perianth is common in lilies, narcissus, hyacinths, &amp;c. It may be also
+met with occasionally among orchids. The lily of the valley
+(<i>Convallaria maialis</i>) seems also to be particularly subject to an
+increase in the number of parts of which its perianth consists, the
+augmentation being due partly to repetition or pleiotaxy, partly to the
+substitution of petaloid segments for stamens and pistils.<a name="FNanchor_433_433" id="FNanchor_433_433"></a><a href="#Footnote_433_433" class="fnanchor">[433]</a></p>
+
+<p>In this place may also be mentioned the curious deviation from the
+ordinary structure occasionally met with in <i>Lilium candidum</i>, and known
+in English gardens as the double white lily. In this case there are no
+true flowers, but a large number of petal-like segments<span class='pagenum'><a name="Page_376" id="Page_376">[Pg 376]</a></span> disposed in an
+irregular spiral manner at the extremity of the stem, some of the
+uppermost being occasionally verticillate.<a name="FNanchor_434_434" id="FNanchor_434_434"></a><a href="#Footnote_434_434" class="fnanchor">[434]</a></p>

+
+<p><b>Pleiotaxy of the corolla.</b>&mdash;With reference to double flowers, it was
+remarked by Linn&eacute; that polypetalous flowers were, as he said,
+multiplied, while monopetalous flowers were duplicated, or triplicated,
+as the case may be,<a name="FNanchor_435_435" id="FNanchor_435_435"></a><a href="#Footnote_435_435" class="fnanchor">[435]</a> a statement that is true in the main, though
+it<span class='pagenum'><a name="Page_377" id="Page_377">[Pg 377]</a></span> requires modification. In the case of polypetalous, or rather
+dialypetalous flowers, the petals may be very largely increased by
+multiplication, as in roses, anemones, pinks, &amp;c. In the last-named
+genus the number is often so much increased that the calyx splits from
+the tension exercised on it by the increasing mass within. This
+multiplication may happen without any metamorphy or substitution of
+petals for stamens, though, in the majority of cases, it is associated
+with such a change. It is curious to observe in some of these flowers
+that the total number of parts is not greatly increased; thus, in some
+of the double-flowered <i>Leguminos&aelig;</i>, such as <i>Ulex europ&aelig;us</i> and <i>Lotus
+corniculatus</i>, the petals are repeated once or twice, the stamens are
+petalodic, but reduced in number, while the carpels are usually entirely
+wanting. Thus, owing to the diminished number of parts in the inner
+whorls of the flower, these very double-looking blooms do not contain
+any greatly increased number of parts.<a name="FNanchor_436_436" id="FNanchor_436_436"></a><a href="#Footnote_436_436" class="fnanchor">[436]</a></p>
+
+<p>Flowers that, under ordinary circumstances, are gamopetalous, become, in
+some instances, multiplied by the formation of additional segments, just
+as in the case of polypetalous corollas; but in these cases the corollas
+become polypetalous, their petals do not cohere one with another. Among
+double flowers of this character may be mentioned <i>Campanula
+rotundifolia</i>, <i>Gardenia</i> sp., <i>Nerium Oleander</i>, <i>Serissa</i> sp.,
+<i>Arbutus Unedo</i>, &amp;c. The change is associated with petalody of the
+stamens and pistils.</p>
+
+<p>A more frequent change among the monopetalous orders is the duplication
+or triplication of the corolla, in consequence of which there appear to
+be a series of corollas enclosed one within the other, the lobes of
+which generally alternate with one another, but which sometimes are
+superposed. This happens occasionally in the primrose (<i>Primula
+acaulis</i>), and constitutes the variety called by the gardeners "hose in
+hose."</p><p><span class='pagenum'><a name="Page_378" id="Page_378">[Pg 378]</a></span></p>
+
+<p>The same condition occurs frequently in some species of <i>Datura</i> and

+</div>
+
+<p>In <i>Antirrhinum majus</i> double flowers of this character sometimes occur;
+the outermost corolla is normal, the succeeding ones usually have their
+petals separate one from the other; the stamens are sometimes present,
+sometimes absent, and at other times petalodic. Similar occurrences may
+be met with in labiates and jasmines, and in <i>Erica hyemalis</i>.</p>
+
+<p>Mr. W. B. Hemsley has kindly furnished me with flowers of a similar kind
+occurring in wild specimens of<span class='pagenum'><a name="Page_379" id="Page_379">[Pg 379]</a></span> <i>Epacris impressa</i>,<a name="FNanchor_437_437" id="FNanchor_437_437"></a><a href="#Footnote_437_437" class="fnanchor">[437]</a> and there are
+analogous phenomena in the common honeysuckle (<i>Lonicera Periclymenum</i>),
+in which three corollas and no stamens often occur.</p>
+
+<p>This duplication may either be accounted for on the theory of chorisis
+above alluded to, or by supposing that the extra corolline whorl is due
+to a series of confluent petalodic stamens; that the latter is the true
+explanation, in certain cases at least, is shown by some flowers of
+<i>Datura fastuosa</i>, in which the second corolla was partially staminal in
+its appearance, and bore nearly perfect anthers, in addition to the five
+ordinary stamens, which were unaltered either in form or position. Some
+partially virescent honeysuckle flowers have a similar structure.</p>
+
+<p>There are other cases of apparent multiplication or duplication, due,
+probably, rather to the formation of outgrowths from the petals than to
+actual augmentation of their number. These excrescences occur sometimes
+on the inner surface of the petals, or of the corolla; at other times on
+the outer surface, as in some gloxinias, &amp;c. This matter will be more
+fully treated of under the head of hypertrophy and enation.</p>
+
+
+
+<p><b>Pleiotaxy of the andr&oelig;cium.</b>&mdash;An increase in the number of whorls in
+the stamens is very common, especially in cases where the number of
+circles of stamens is naturally large. The augmentation of the number of
+stamens is still more frequent where these organs are arranged, not in
+verticils, but in one continuous spiral line.</p>
+
+<p>In <i>Crucifer&aelig;</i> there is always an indication of two whorls of stamens,
+and this indication is rendered even more apparent in some varieties
+accidentally met with. So in <i>Saponaria</i>, in <i>Dianthus</i>, and other
+<i>Caryophylle&aelig;</i>, three and four verticils of stamens have been met with.
+In <i>Lonicera Periclymenum</i> a second whorl of stamens more or less
+petalodic sometimes occurs.</p>
+
+<p>Moquin mentions a variety of <i>Rubus fruticosus</i> in<span class='pagenum'><a name="Page_380" id="Page_380">[Pg 380]</a></span> which nearly 900
+petaloid organs existed in the place of the twenty-five or thirty
+stamens natural to the plant, the other organs of the flower being in
+their ordinary condition, with the exception of the pistil, which did
+not attain its full size. Baillon records the occasional existence of
+two rows of stamens in <i>Ditaxis lancifolia</i>.</p>
+
+
+
+<p><b>Increased number of stamens in orchids, &amp;c.</b>&mdash;Various deviations from the
+ordinary type of orchid structure have been already alluded to under the
+head of displacement, fusion, peloria, substitution, &amp;c., but the
+alterations presented by the andr&oelig;cium in this family are so
+important in reference to what is considered its natural conformation,
+that it seems desirable, in this place, to enter upon the teratological
+appearances presented by the andr&oelig;cium in this order, in somewhat
+greater detail than usual. The ordinary structure of the flower with its
+three sepals, two petals, labellum, column; and inferior ovary, is well
+known. Such a conformation would be wholly anomalous and inexplicable
+were it not that the real number and arrangement of parts have been
+revealed by various workers labouring to the same end in different
+fields. Thus, Robert Brown, Link, Bauer, Darwin, and others, paid
+special attention to the minute anatomy and mode of distribution of the
+vessels; Irmisch, Crueger, Payer, and others, to the evolution of the
+flower; Lindley, St. Hilaire, and Reichenbach, to the comparison of the
+completed structures in the various genera and species; while the
+teratological observers have been numerous, as will be seen from the
+selected references cited at the end of this paragraph and in other
+places. The result of this manifold study has been a pretty general
+agreement that the structure of the order (omitting minor details) is as
+follows:&mdash;A six-parted perianth in two rows, the outer three (sepals)
+generally regular and equal in shape; of the inner three (petals or
+tepals) two are regular, and one, the labellum very<span class='pagenum'><a name="Page_381" id="Page_381">[Pg 381]</a></span> irregular,
+consisting not only of a petal, but of two abortive stamens incorporated
+with it. The column is considered to be made up of one perfect and three
+abortive stamens, in inseparable connection with three styles. By some,
+however, it is supposed that all the stamens are confluent with the
+column and none with the lip.</p>

+All that can be done in these pages is to set forth the evidence
+furnished by teratology as to this matter&mdash;evidence for the most part
+accumulated and recorded without any special reference to any theory of
+orchid structure.</p>
+
+<p>The following details all refer to flowers in which the number of
+stamens in orchidaceous plants was increased beyond what is necessary.
+They are arranged with reference to the number of adventitious organs,
+beginning with those in which the number was smallest, and proceeding
+thence to those in which it was greatest. In some cases it has not been
+possible to ascertain whether the adventitious organs were really
+restorations of the numerical symmetry, substitutions of one part for
+another, stamen for petal, &amp;c., or wholly adventitious productions.
+Unless otherwise stated, the interpretation put upon the facts thus
+recorded is that of the present writer, and not necessarily that of the
+original observer.</p>
+
+<div class="blockquot"><p>Mr. J. T. Moggridge has described and figured a flower of
+<i>Ophrys insectifera</i> in which there was a vestige of a second
+stamen present, probably one of the inner series fig. 192
+(<i>a</i><sup>2</sup>).<a name="FNanchor_439_439" id="FNanchor_439_439"></a><a href="#Footnote_439_439" class="fnanchor">[439]</a> The same observer also records the presence of a
+second anther between the lobes of the normal one. This can
+hardly be referred to either of the typical stamens, but would
+seem to be a perverted development of the rostellum.<a name="FNanchor_440_440" id="FNanchor_440_440"></a><a href="#Footnote_440_440" class="fnanchor">[440]</a></p>

+<i>Orchis morio</i> with two stamens.</p>
+
+<p>In a flower of <i>Habenaria chlorantha</i>, described by the late
+Professor Henslow,<a name="FNanchor_442_442" id="FNanchor_442_442"></a><a href="#Footnote_442_442" class="fnanchor">[442]</a> the outer three stamens are suppressed,
+while two of the inner group are present, as happens normally
+in <i>Cypripedium</i>.<span class='pagenum'><a name="Page_383" id="Page_383">[Pg 383]</a></span></p>
+
+<p>A flower of <i>Cattleya violacea</i> afforded a similar
+illustration; but in this case only one of the inner stamens
+was developed, and this in the form of a small petal, partly
+adherent to the column.</p>
+
+<p>In <i>Dendrobium normale</i>, Falconer, not only is the perianth
+regular, but the column is triandrous,<a name="FNanchor_443_443" id="FNanchor_443_443"></a><a href="#Footnote_443_443" class="fnanchor">[443]</a> the three stamens
+(according to the diagram of its structure given by Lindley)
+pertaining to the outer row.</p>
+
+<p>In a specimen of <i>Dendrobium h&oelig;moglossum</i> kindly forwarded
+from Ceylon by Mr. Thwaites there were three stamens present,
+of which one posterior belonged to the outer series <span class="smcap">A</span> 1, and
+two lateral to the inner <i>a</i> 1, <i>a</i> 2, fig. 192.</p>
+
+<p>M. His observed, several years in succession, some flowers of a
+species of <i>Ophrys</i> with three sepals, no lateral petals, one
+lip, and three perfect stamens. In this case probably the two
+supernumerary stamens were petals which had assumed an
+anther-like character.</p>
+
+<p>Wydler describes a flower of <i>Ophrys aranifera</i> in which one
+outer and two inner stamens were present.<a name="FNanchor_444_444" id="FNanchor_444_444"></a><a href="#Footnote_444_444" class="fnanchor">[444]</a> I have myself
+met with three such flowers in the same species. The stamens
+present were <span class="smcap">A</span> 1, <i>a</i> 1, <i>a</i> 2.</p>
+
+<p>Dr. J. E. Gray exhibited at the Botanical Society of London, in
+August, 1843, a specimen of <i>Ophrys apifera</i> with a triandrous
+column, the supernumerary anthers belonging, apparently, to the
+inner whorl.</p>
+
+<p>In his 'Catalogue of the Plants of South Kent,' p. 56, tab. iv,
+f. 16, the Rev. G. E. Smith describes and figures a flower of
+<i>O. aranifera</i> with a triandrous column, seemingly of the same
+kind as that spoken of by Dr. Gray.</p>
+
+<p>Mr. Moggridge met with a triandrous flower in the same species,
+and refers the appearance to "a fusion of two flowers,
+accompanied by suppression and modification."<a name="FNanchor_445_445" id="FNanchor_445_445"></a><a href="#Footnote_445_445" class="fnanchor">[445]</a> As, however,
+no details are given in support of this opinion, it may be
+conjectured that the two additional stamens were members of the
+inner whorl <i>a</i> 1, <i>a</i> 2, and thus the conformation would be
+the same as in the flowers just mentioned. The figures given by
+Mr. Moggridge bear out this latter view, while they lend no
+support to the hypothesis advanced by him. Nevertheless, no
+decided opinion can be pronounced by those who have not had the
+opportunity of examining the flowers in question.</p>
+
+<p>Alphonse de Candolle<a name="FNanchor_446_446" id="FNanchor_446_446"></a><a href="#Footnote_446_446" class="fnanchor">[446]</a> figures a flower of <i>Maxillaria</i> in
+exactly the same condition, so far as the stamens are
+concerned, as in the Ophrys flowers just mentioned. It is
+curious to observe that in many of these cases the two lateral
+petals are suppressed.</p>
+
+<p>Von Martius mentions the occurrence of three anthers

+
+<p>The writer has examined, in the Royal Gardens at Kew, a flower
+of <i>Cattleya crispa</i> in which were three stamens, the central
+one normal; the two lateral ones, belonging probably to the
+inner whorl, were in appearance like the lateral petals, and
+one of them was adherent to the central perfect column.
+Duchartre<a name="FNanchor_449_449" id="FNanchor_449_449"></a><a href="#Footnote_449_449" class="fnanchor">[449]</a> mentions a flower of <i>Cattleya Forbesii</i> in
+which there were two labella in addition to the ordinary one,
+the column being in its normal condition. From the analogy of
+other cases it would appear as if the additional labella in
+this instance were the representatives of two stamens of the
+outer whorl. Beer likewise has put on record the existence of a
+triandrous <i>Cattleya</i>.<a name="FNanchor_450_450" id="FNanchor_450_450"></a><a href="#Footnote_450_450" class="fnanchor">[450]</a></p>
+
+<p>A specimen of <i>Catasetum eburneum</i> forwarded by Mr. Wilson
+Saunders was normal so far as the sepals and two lateral petals
+were concerned, but the anterior petal or labellum was flat and
+in form quite like the two lateral ones; the column was normal
+and in the situation of the two anterior stamens of the outer
+series <span class="smcap">A</span> 2, <span class="smcap">A</span> 3, were two labella of the usual form (fig. 156,
+p. 291). Perhaps the <i>Oncidium</i> represented at p. 68, fig. 29,
+may also be explained on the supposition that the two lateral
+lobes of the labellum in this flower were the representatives
+of stamens.</p>
+
+<p>In Fig. 193 is shown the arrangement of parts in a flower of
+<i>Ophrys aranifera</i>. Here there were three sepals, two lateral
+petals, one of which was adherent to the side of the column;
+the central labellum was seemingly deficient, but there were
+two pseudo-labella placed laterally in the position of the two
+antero-lateral stamens of the outer series (<span class="smcap">A</span> 2, <span class="smcap">A</span> 3). Within
+these was another perfect stamen occupying the position of the
+anterior stamen of the inner series (<i>a</i> 3). In another flower
+of the same species, gathered at the same time (fig. 194),
+there were three sepals not at all different from those of the
+normal flower. The three petals next in succession were also,
+in form and position, in their ordinary state. In colour,
+however, the two upper lateral petals differed from what is
+customary, in having the same purplish-brown tint which
+characterises the lip. Within these petals, at the upper part
+of the flower, there was the ordinary column, and at the
+opposite side, alternating with the petals before mentioned,
+two additional lip-like petals, one provided with a half-anther
+containing a single perfectly formed pollen-mass (<span class="smcap">A</span> 2, <span class="smcap">A</span> 3). It
+is, perhaps, worthy of notice that the arrangement<span class='pagenum'><a name="Page_385" id="Page_385">[Pg 385]</a></span> of the
+coloured spots on the true labellum, and that on the
+adventitious lips, replacing the two lower of the outer
+stamens, were not of a similar character. The supernumerary
+lips had the <span class="greek" title="[Greek: pi]">&pi;</span>-shaped marking which is so common in
+this species, while the true lip was, as to its spots, much
+more like <i>O. apifera</i>. Alternating with this last whorl were
+three columns, all apparently perfectly formed and differing
+only from the ordinary one in their smaller size and
+corresponding to <i>a</i> 1, <i>a</i> 2, <i>a</i> 3. The ovary in this flower
+was two-celled, with four parietal placentas, thus giving an
+appearance as though there had been a fusion of two or more
+flowers associated with suppression and other changes. The
+position of the supernumerary organs and the absence of any<span class='pagenum'><a name="Page_386" id="Page_386">[Pg 386]</a></span>
+positive sign of fusion in the bracts or other part of the
+flower, seemed, however, to negative the idea of fusion.<a name="FNanchor_451_451" id="FNanchor_451_451"></a><a href="#Footnote_451_451" class="fnanchor">[451]</a></p>

+
+<p>A similar illustration, for a knowledge of which the writer is
+indebted to the kindness of Professor Asa Gray and Mr. Darwin,
+occurred in some specimens of <i>Pogonia ophioglossoides</i>
+collected by Dr. J. H. Paine in a bog near Utica, New York. It
+will be seen from the following description that these flowers
+presented an almost precisely similar condition to those of the
+<i>Ophrys aranifera</i> just mentioned. "The peculiarities of these
+flowers," writes Professor Gray, "are that they have three
+labella, and that the column is resolved into small petaloid
+organs. The blossom is normal as to the proper perianth, except
+that the labellum is unusually papillose, bearded almost to the
+base. The points of interest are, first, that the two accessory
+labella are just in the position of the two suppressed stamens
+of the outer series, viz. of <span class="smcap">a</span>2 and <span class="smcap">a</span>3, as represented in the
+diagram, fig. 192; and there is a small petaloid body on the
+other side of the flower, answering to the other stamen, <span class="smcap">a</span>1.
+Secondly, in one of the blossoms, and less distinctly in
+another, two lateral stamens of the inner series (<i>a</i>1 and
+<i>a</i>2) are represented each by a slender naked filament. There
+are remaining petaloid bodies enough to answer for the third
+stamen of the inner series and for the stigmas, but their order
+is not well to be made out in the dried specimens." It may here
+be mentioned that <i>Isochilus</i> is normally triandrous.</p>
+
+<p>A tetrandrous flower of <i>Cypripedium</i> has also been recorded.</p>
+
+<p>In <i>Isochilus</i>, according to Cruger, there are often five
+stamens, and<span class='pagenum'><a name="Page_387" id="Page_387">[Pg 387]</a></span> there are several, besides those already
+mentioned, in which six more or less perfect stamens have been
+seen&mdash;of these the following may be taken as illustrations. A
+hexandrous flower of <i>Orchis militaris</i> has been recorded by
+Kirschleger,<a name="FNanchor_452_452" id="FNanchor_452_452"></a><a href="#Footnote_452_452" class="fnanchor">[452]</a> and in the accompanying diagram (fig. 195),
+from Cramer,<a name="FNanchor_453_453" id="FNanchor_453_453"></a><a href="#Footnote_453_453" class="fnanchor">[453]</a> of a monstrous flower of <i>Orchis mascula</i>,
+there is one perfect stamen of the outer row and two lip-like
+stamens of the same series, while the inner verticil comprises
+one perfect and two abortive stamens.</p>

+
+<p>Morren<a name="FNanchor_454_454" id="FNanchor_454_454"></a><a href="#Footnote_454_454" class="fnanchor">[454]</a> describes some flowers of <i>Orchis morio</i> in which
+there were three sepals, three petals, and within the latter
+two other ternary series of petals; this would seem to be a
+case of petalody of all six stamens. Morren, however, seems to
+have considered the additional segments as repetitions of the
+corolline whorl, though he describes a central mass as the
+column bearing a "<i>souvenir</i> of the anther." Nevertheless,
+there is no decisive evidence either in his figure or his
+description in support of his opinion as to the nature of the
+central mass, which might be a distorted condition of the
+styles, or, as is more probable, a rudimentary and irregular
+flower. Morren also describes another flower of the same plant
+in which there were three sepals, two lateral petals partially
+lip-like in aspect, a third labellum normal, two additional
+labella representing the two anterior stamens of the outer
+whorl, while more or less developed rudiments of the remaining
+four stamens also exist.</p>
+
+<p>While, in most cases, the supernumerary stamens can, by reason
+of their relative position, their complete or partial
+antheriferous nature, be safely referred to one or other of the
+six stamens, making up a typical orchid flower, there are other
+specimens in which the additional stamens are altogether
+adventitious, and do not admit of reference to the homologue.
+Thus it was in a specimen of <i>Odontoglossum Alexandr&aelig;</i> examined
+by the writer, and in which, within a normally constructed
+perianth, there were six columns, all polliniferous, but
+arranged in so confused and complicated a manner that it was
+impossible to make out any definite relation in their position.
+There was nothing to indicate a fusion of flowers, but rather
+an extension of the centre of the flower, and consequent
+displacement of the stamens, &amp;c. Again, the existence of
+adventitious stamens does not necessarily imply the development
+of organs usually suppressed, inasmuch as they may result from
+the assumption by the lateral petals of staminal
+characteristics.</p>
+
+<p>Nevertheless, as far as teratology is concerned, specimens may
+be found in which some or all of the usually suppressed stamens
+of <i>Orchidace&aelig;</i> may be found. These stamens may be all perfect
+(polliniferous), or, as is more frequently the case, more or
+less petal-like. Moreover,<span class='pagenum'><a name="Page_388" id="Page_388">[Pg 388]</a></span> when the stamens are petalodic, the
+form assumed is usually that of the labellum.</p>
+
+<p>The presence of stamens in undue numbers in orchids is very
+generally, but not always, attended by some coincident
+malformation, of which the most frequent is cohesion of two or
+more sepals, and consequent displacement or adhesion of one
+petal to the side of the column. Petalody of the styles and
+median prolification are also sometimes found in association
+with an augmented number of stamens. </p></div>

+
+<p><b>Pleiotaxy of the gyn&oelig;cium.</b>&mdash;An increase in the number of whorls of
+which the pistil consists is not of very frequent occurrence. Generally
+after the formation of the whorl of carpels, the energy of the growing
+point ceases, or if by chance it be continued, the result is more
+generally the production of a new flower-bud (median prolification) than
+the repetition of the carpellary series. It is necessary also to
+distinguish between the veritable augmentation of the pistil and the
+semblance of it, brought about by the substitution of carpels for some
+other organs, as pistillody of the stamens, and even of the segments of
+the perianth, is not very unfrequent, as has already been stated under
+the head of substitution. Again, the increased number of carpels which
+is sometimes met with in such flowers, as <i>Magnolia</i> or <i>Delphinium</i>,
+where the ovaries are arranged<span class='pagenum'><a name="Page_389" id="Page_389">[Pg 389]</a></span> in spiral series, is not strictly
+referable to the present category.</p>
+
+<p>The orange is one of the plants most frequently subject to an
+augmentation in the number of carpellary whorls; sometimes this is due
+to the stamens assuming the guise of carpels, but at other times the
+increase occurs without any alteration in the stamens or other organs.
+If the adventitious carpels be exposed, they are covered with yellow
+rind, while those portions that are covered by the primary carpels are
+destitute of rind. Some varieties of the double tulip are very subject
+to a similar change, but, in this case, the petals and the stamens very
+frequently become more or less carpellary in their nature. Fig. 196
+represents an increased number of whorls of carpels in the variety
+called "rex rubrorum," the segments of the perianth having been removed.</p>
+
+<p>In the St. Valery apple, already referred to, there is a second whorl of
+carpels above the first, a fact which has been made use of to explain
+the similar structure of the pomegranate.</p>
+
+<p>The tomato (<i>Lycopersicum esculentum</i>) is another plant in which an
+adventitious series is frequently produced, and generally in combination
+with the primary series.</p>
+
+<p>In the Chinese primrose (<i>Primula sinensis</i>) a supernumerary whorl is
+frequently met with, generally associated with other changes in the
+construction and arrangement of the parts of the flower.</p>

+<p>M. de Candolle<a name="FNanchor_455_455" id="FNanchor_455_455"></a><a href="#Footnote_455_455" class="fnanchor">[455]</a> mentions a flower of <i>Gentiana purpurea</i> with four

+of carpels above the first in <i>Vinca herbacea</i>. Dr. Sankey has forwarded
+flowers of a <i>Pelargonium</i> having a double series of carpels, eight in
+the outer row, five in the inner, and this condition is stated to exist
+in the flowers<span class='pagenum'><a name="Page_390" id="Page_390">[Pg 390]</a></span> of the same plant for two years consecutively. In

+carpels.<a name="FNanchor_457_457" id="FNanchor_457_457"></a><a href="#Footnote_457_457" class="fnanchor">[457]</a> Meissner records a similar augmentation in <i>Polygonum

+there were two carpels intervening between the ordinary pair, and a
+similar illustration has been observed by the writer in <i>Allamanda
+cathartica</i>. Eichler<a name="FNanchor_460_460" id="FNanchor_460_460"></a><a href="#Footnote_460_460" class="fnanchor">[460]</a> has put on record a similar case in a

+Musschianum</i>). The supernumerary carpels in this flower were placed on a
+short axis, which originated in the axils of the stamens, and as these
+latter organs were present in their usual number and position, the
+adventitious carpels could not be considered as resulting from a
+transformation, or substitution of carpels for stamens.</p>
+
+<p>Lastly, the instance cited by Dr. Allman<a name="FNanchor_462_462" id="FNanchor_462_462"></a><a href="#Footnote_462_462" class="fnanchor">[462]</a> in <i>Saxifraga Geum</i> may be
+alluded to. Here there was a row of adventitious carpels between the
+stamens and pistils, the backs of the carpels being turned towards the
+axis of the flowers. Dr. Allman explains the presence of the
+supernumerary parts by the supposed production of a whorl of secondary
+axes between the stamens and the centre of the flower. These axes are
+further supposed to bear imperfect flowers, of which the additional
+carpels are the only traces, but this explanation seems forced.</p>

+
+DIMINISHED NUMBER OF ORGANS.</h3>
+
+
+<p>A diminution in the number of parts is generally due to suppression,
+using that word as the equivalent of non-development. It corresponds
+thus in meaning with the <i>Fehlschlagen</i> of the Germans, the <i>avortement
+compl&egrave;te</i> of Moquin and other French writers. It differs from atrophy,
+or partial abortion, inasmuch as the latter terms apply to instances
+wherein there has been a partial development, and in which evolution has
+gone on to a certain extent, but has, from some cause or other, been
+checked. These cases will be found under the head of diminished size of
+organs. As the word abortion is used by different authors in different
+ways, it is the more necessary to be as precise as possible in the
+application of the term. In the present work abortion is used to apply
+to cases wherein parts have been formed, but wherein growth has been
+arrested at a certain stage, and which, therefore, have either remained
+<i>in statu quo</i>, while the surrounding parts have increased, or have,
+from pressure or other causes, actually diminished in size.</p>
+
+<p>In practice, however, it is not always possible to discriminate between
+those instances in which there has been a true suppression, an absolute
+non-development of any particular organ, and those in which it has been
+formed, and has grown for a time, but has afterwards ceased to do so,
+and has been gradually<span class='pagenum'><a name="Page_393" id="Page_393">[Pg 393]</a></span> obliterated by the pressure exercised by the
+constantly increasing bulk of adjacent parts, or possibly has become
+incorporated with them. In the adult flower the appearances are the
+same, though the causes may have been different.</p>
+
+
+
+
+<h4><a name="CHAPTER_I9" id="CHAPTER_I9"></a>CHAPTER I.<br />
+
+SUPPRESSION OF AXILE ORGANS.</h4>
+
+
+<p>Absolute suppression of the main axis is tantamount to the non-existence
+of the plant, so that the terms "acaulescent," "acaulosia," etc, must be
+considered relatively only, and must be taken to signify an atrophied or
+diminished size of the stem, arising from the non-development of the
+internodes.</p>
+
+<p>The absence of lateral branches or divisions of the axis is of frequent
+occurrence, and is dependent on such causes as the following:&mdash;deficient
+supply of nutriment, position against a wall or other obstacle, close
+crowding of individual plants, too great or too little light, too rich
+or too poor a soil, &amp;c.</p>
+
+<p>Probably the absence of the swollen portion below the flower in the case
+of many proliferous roses, double-flowered apples, as already referred
+to, may be dependent on the non-development of the extremity of the
+peduncle or flower-stalk. Thus, in a double-flowered apple recently
+examined, there was a sort of involucel of five perfect leaves, then
+five sepals surrounding an equal number of petals, numerous stamens, and
+five styles, but not a trace of an expanded axis, nor of any portion of
+the carpels, except the styles. The views taken as to the nature of this
+and similar malformations must depend on the opinion held as to the
+nature of inferior pistils, and on the share, if any, that the expanded
+axis takes in their production. As elsewhere said, the<span class='pagenum'><a name="Page_394" id="Page_394">[Pg 394]</a></span> evidence
+furnished by teratology is conflicting, but there seems little or
+nothing to invalidate the notion that the end of the flower-stalk and
+the base of the calyx may, to a varying extent, in different cases,
+jointly be concerned in the formation of the so-called calyx-tube and of
+the inferior ovary. Obviously it is not proper to apply to all cases
+where there is an inferior ovary the same explanation as to how it is
+brought about.</p>
+
+<p>As these pages are passing through the press, M. Casimir de Candolle has
+published a different explanation as to the nature of the hip of the
+rose, having been led to his opinion by the conclusion that he has
+arrived at, that the leaf is to be considered in the light of a
+flattened branch, whose upper or posterior surface is more or less
+completely atrophied.</p>
+
+<p>According to M. de Candolle, the calyx-tube, in the case of the rose, is
+neither a whorl of leaves, nor a concave axis in the ordinary sense in
+which those terms are used, but is rather to be considered as a
+ring-like projection from an axis arrested in its ulterior development.
+The secondary projections from the original one correspond to an equal
+number of vascular bundles, and develope into the sepals, petals,
+stamens, and ovaries. If these organs remained in a rudimentary
+condition, the tube of the calyx would be reduced to the condition of a
+sheathing leaf. The rose flower, then, according to M. de Candolle, may
+be considered as a sheathing leaf, whose fibro-vascular system is
+complete, and from which all possible primary projections are
+developed.<a name="FNanchor_464_464" id="FNanchor_464_464"></a><a href="#Footnote_464_464" class="fnanchor">[464]</a></p>
+
+<p>If, as M. de Candolle considers, the leaf and the branch differ merely
+in the fact that the vascular system is complete in the latter, and
+partly atrophied in the former, it would surely be better to consider
+the "calyx-tube" of the rose as a concave axis rather than as a leaf,
+seeing that he admits the fibro-vascular system to be complete in the
+case of the rose.</p><p><span class='pagenum'><a name="Page_395" id="Page_395">[Pg 395]</a></span></p>
+
+<p>With reference to this point the reader is referred to Mr. Bentham's
+account of the morphology and homologies of the <i>Myrtace&aelig;</i> in the
+'Journal of the Linnean Society,' vol. x, p. 105. See also <i>ante</i>, pp.
+71, 77.</p>
+
+<p>Some doubts also exist as to the nature of the beak or columella of such
+fruits as those of <i>Geraniace&aelig;</i>, <i>Malvace&aelig;</i>, <i>Umbellifer&aelig;</i>,
+<i>Euphorbiace&aelig;</i>, &amp;c. The nature of the organ in question may probably be
+different in the several orders named; at any rate the subject cannot be
+discussed in this place, and it is mentioned here because, now and then,
+it happens that the organ in question is completely wanting, and hence
+affords an illustration of suppression.</p>

+
+SUPPRESSION OF FOLIAR ORGANS.</h4>
+
+
+<p>This subject may be considered, according as the separate leaves of the
+stem or of the flower are affected, and according as either the number
+of members of distinct whorls, or that of the whorls themselves, is
+diminished.</p>
+
+<p>The terms aphylly, meiophylly, and meiotaxy may be employed, according
+as the individual leaves are altogether wanting, or with reference to
+the diminished number of parts in a whorl, or a decrease in the
+verticils.</p>
+
+
+
+<p><b>Aphylly.</b>&mdash;Entire suppression of the leaves is a rare phenomenon. Under
+ordinary circumstances it occurs in most <i>Cactace&aelig;</i>, in some of the
+succulent Euphorbias, and other similar plants, where the epidermal
+layers of the stem fulfil the functions of leaves. But even in these
+plants leaf-like organs are present in some stage or another of the
+plant's life.</p><p><span class='pagenum'><a name="Page_396" id="Page_396">[Pg 396]</a></span></p>
+
+<p>Partial suppression of the leaf occurs sometimes in compound leaves,
+some or other of the leaflets of which are occasionally suppressed.
+Sometimes, as Moquin remarks, it is the terminal leaflet which is
+wanting, when the appearance is that of <i>Cliffortia</i>, at other times the
+lateral leaflets are deficient, as in <i>Citrus</i> or <i>Phyllarthron</i>.
+<i>Ononis monophylla</i> and <i>Fragaria monophylla</i> may be cited as instances
+of the suppression of the lateral leaflets. If the blade of the leaf
+disappears entirely, we have then an analogous condition to that of the
+phyllodineous acacias.</p>
+
+<p>With reference to the strawberry just mentioned, Duchesne, 'Hist. Nat.
+Frais.,' p. 133, says that this was a seedling raised from the <i>fraisier
+des bois</i>, and the characters of which were reproduced by seed, and have
+now become fixed. The monophyllous condition has been considered to be
+the result of fusion of two or more leaflets, but however true this may
+be in some cases, it is not the case with this strawberry. M. Paillot
+states that he has found the variety in a wild state.<a name="FNanchor_465_465" id="FNanchor_465_465"></a><a href="#Footnote_465_465" class="fnanchor">[465]</a></p>
+
+<p>In like manner varieties of the following plants occur with simple
+leaves, <i>Rosa berberifolia</i> (<i>Lowea</i>), <i>Rubus Id&aelig;us</i>, <i>Robinia
+pseudacacia</i>, <i>Fraxinus excelsior</i>, <i>Sambucus nigra</i>, <i>Juglans nigra</i>,
+&amp;c.</p>
+
+<p>In one instance seen by the writer every portion of the leaf of a rose
+was deficient, except the stipules and a small portion of the petiole.
+(See abortion.)</p>
+
+
+
+<p><b>Meiophylly.</b>&mdash;A diminished number of leaves in a whorl occasionally takes
+place; thus, in some of the <i>Stellat&aelig;</i>, and frequently in <i>Paris
+quadrifolia</i>, the number of leaves in the verticil is reduced. Care must
+be exercised in such instances that an apparent diminution arising from
+a fusion of two or more leaves be not confounded with suppression.</p>
+
+
+
+<p><b>Meiophylly of the calyx or perianth.</b>&mdash;A lessened number<span class='pagenum'><a name="Page_397" id="Page_397">[Pg 397]</a></span> of sepals is
+not a very common occurrence among dicotyledonous plants. Seringe
+figures a proliferous flower of <i>Arabis alpina</i> with two sepals only,
+and a similar occurrence has been noticed in <i>Diplotaxis tenuifolia</i>.</p>
+
+<p>In <i>Cattleya violacea</i> the writer has met with a flower in which the
+uppermost sepal was entirely wanting, while two of the lateral petals
+were fused together. Moquin records that in some of the flowers of
+<i>Chenopodiace&aelig;</i>, in which the inflorescence is dense, a suppression of
+two or three sepals sometimes occurs. The species mentioned are <i>Ambrina
+<ins title="ambrosiodes in original">ambrosioides</ins></i>, <i>Chenopodium glaucum</i>, and <i>Blitum polymorphum</i>.</p>
+
+
+
+<p><b>Meiophylly of the corolla.</b>&mdash;Suppression of one or more petals is of more
+frequent occurrence than the corresponding deficiency in the case of the
+sepals. Among <i>Caryophyllace&aelig;</i> imperfection as regards the numerical
+symmetry of the flower is not uncommon, as in species of <i>Cerastium</i>,
+<i>Sagina</i>, <i>Dianthus</i>, &amp;c. In <i>Ranunculace&aelig;</i> the petals are likewise not
+unfrequently partially or wholly suppressed. A familiar illustration of
+this is afforded by <i>Ranunculus auricomus</i>, in which it is the exception
+to find the corolla perfect.<a name="FNanchor_466_466" id="FNanchor_466_466"></a><a href="#Footnote_466_466" class="fnanchor">[466]</a> Some varieties of <i>Corchorus
+acutangulus</i> in west tropical Africa are likewise subject to the same
+peculiarity. Amongst <i>Papilionace&aelig;</i> absence of the carina or of the al&aelig;
+is not uncommon, as in <i>Trifolium repens</i>, <i>Faba vulgaris</i>, &amp;c.</p>
+
+<p>Moquin relates a case of the kind in the haricot bean, in which the
+carina was entirely absent, and another in the pea, where both carina
+and al&aelig; were missing, thus reducing the flower to the condition that is
+normal in <i>Amorpha</i> and <i>Afzelia</i>. Suppression of the upper lip in such
+flowers as <i>Calceolaria</i> has been termed by Morren "apilary."</p><p><span class='pagenum'><a name="Page_398" id="Page_398">[Pg 398]</a></span></p>
+
+<p>In <i>Orchidace&aelig;</i> entire absence of the labellum, frequently without any
+other perceptible change, is of common occurrence. The writer has seen
+numerous specimens of the kind in <i>Ophrys apifera</i> and <i>O. aranifera</i>;
+also in <i>Dendrobium nobile</i>, <i>&AElig;rides odoratum</i>, <i>Cypripedium villosum</i>,
+<i>Listera ovata</i>, &amp;c. Morren<a name="FNanchor_467_467" id="FNanchor_467_467"></a><a href="#Footnote_467_467" class="fnanchor">[467]</a> mentions analogous deficiencies in
+<i>Zygopetalum maxillare</i>, <i>Calanthe</i> sp., and <i>Cattleya Forbesii</i>. In
+most of these there was also a fusion of the two lower sepals, which
+were so twisted out of place as to occupy the situation usually held by
+the labellum. At the same time the column was partially atrophied. To
+this deficiency of the lip the author just quoted proposed to apply the
+term acheilary, <span class="greek" title="[Greek: a-cheilarion]">&#945;-&#967;&#949;&#953;&#955;&#945;&#961;&#953;&#959;&#957;</span>. Mr. Moggridge has communicated to
+the author an account of certain flowers of <i>Ophrys aranifera</i>, in which
+the petals were deficient, sometimes completely, at other times one or
+two only were present.</p>
+
+
+
+<p><b>Meiophylly of the andr&oelig;cium.</b>&mdash;Suppression of one or more stamens,
+independently of like defects in other whorls, is not uncommon, even as
+a normal occurrence, <i>e.g.</i> in <i>Carlemannia</i>, where the flower, though
+regular, has only two stamens, and other similar deficiencies are common
+in Dilleniads.</p>
+
+<p>Seringe relates the occurrence of suppression of some of the stamens in
+<i>Diplotaxis tenuifolia</i>,<a name="FNanchor_468_468" id="FNanchor_468_468"></a><a href="#Footnote_468_468" class="fnanchor">[468]</a> St. Hilaire in <i>Cardamine hirsuta</i>, others
+in <i>C. sylvatica</i>.</p>
+
+<p>In <i>Caryophyllace&aelig;</i> suppression of one or more stamens has been observed
+in <i>Mollugo cerviana</i>, <i>Arenaria tetraquetra</i>, <i>Cerastium</i>, &amp;c.<a name="FNanchor_469_469" id="FNanchor_469_469"></a><a href="#Footnote_469_469" class="fnanchor">[469]</a>
+Among violets the writer has observed numerous flowers in which two or
+three stamens were suppressed. Chatin<a name="FNanchor_470_470" id="FNanchor_470_470"></a><a href="#Footnote_470_470" class="fnanchor">[470]</a> alludes to a similar
+reduction in <i>Trop&aelig;olum</i>, while in flowers that are usually didynamous
+absence of two or more of the stamens is not unfrequent, <i>e.g.</i> in
+<i>Antirrhinum</i>, <i>Digitalis</i>,<span class='pagenum'><a name="Page_399" id="Page_399">[Pg 399]</a></span> while in a flower of <i>Catalpa</i> a solitary
+perfect stamen, and a complete absence of the sterile ones usually
+present, have been observed. This might have been anticipated from the
+frequent deficiencies in the staminal whorl in these plants under what
+are considered to be normal conditions. Reduction of the staminal whorl
+is also not unfrequent in <i>Trifolium repens</i> and <i>T. hybridum</i>, and has
+been seen in <i>Delphinium</i>, &amp;c.<a name="FNanchor_471_471" id="FNanchor_471_471"></a><a href="#Footnote_471_471" class="fnanchor">[471]</a></p>
+
+
+
+<p><b>Meiophylly of the gyn&oelig;cium.</b>&mdash;Numerical inequality in the case of the
+pistil, as compared with the other whorls of the flower, is of such
+common occurrence, under ordinary circumstances, that in some text-books
+it is looked on as the normal condition, and a flower which is isomerous
+in the outer whorls is by some writers not considered numerically
+irregular if the number of the carpels does not coincide with that of
+the other organs.</p>
+
+<p>But in this place it is only necessary to allude to deviations from the
+number of carpels that are ordinarily found in the particular species
+under observation. As illustrations the following may be
+cited:&mdash;<i>Arenaria tetraqueta</i>, which has normally three styles, and a
+six-valved capsule, has been seen with two styles, and a four or
+five-valved capsule. Moquin relates an instance in <i>Polygala vulgaris</i>
+where there was but a single carpel, a condition analogous to that which
+occurs normally in the allied genus <i>Mozinna</i>. <i>Reseda luteola</i>
+occasionally occurs with two carpels only, while Aconites, Delphiniums,
+Nigellas, and P&aelig;onies frequently experience a like diminution in their
+pistil.</p>
+
+<p>In a flower of <i>Papaver Rh&aelig;as</i> the writer has recently met with an ovary
+with four stigmas and four parietal placent&aelig; only, and to Mr.
+Worthington Smith he is indebted for sketches of crocus blooms with two,
+and in one instance only a solitary carpel.</p>
+
+<p>Moquin cites the fruit of a wild bramble (<i>Rubus</i>)<span class='pagenum'><a name="Page_400" id="Page_400">[Pg 400]</a></span> in which all the
+little drupes which go to make up the ordinary fruit were absent, except
+one, which thus resembled a small cherry. In <i>Crat&aelig;gus</i> the pistil is
+similarly reduced to a single carpel, as in <i>C. monogyna</i>.</p>
+
+<p>The writer has on more than one occasion met with walnuts (<i>Juglans</i>)
+with a single valve and a single suture.<a name="FNanchor_472_472" id="FNanchor_472_472"></a><a href="#Footnote_472_472" class="fnanchor">[472]</a> If the ovary of <i>Juglans</i>
+normally consisted of two valvate carpels, the instances just alluded to
+might possibly be explained by the suppression of one carpel, but the
+ovary in <i>Juglans</i> is at first one-celled according to M. Casimir de
+Candolle.</p>
+
+<p>Among monocotyledons <i>Convallaria majalis</i> may be mentioned as very
+liable to suffer diminution in the number of its carpels, either
+separately or in association with other changes.<a name="FNanchor_473_473" id="FNanchor_473_473"></a><a href="#Footnote_473_473" class="fnanchor">[473]</a></p>
+
+
+
+<p><b>Meiophylly of the flower as a whole.</b>&mdash;In the preceding sections a
+reduction in the parts of each individual whorl has been considered
+without reference to similar diminution in neighbouring verticils. It
+more commonly happens, nevertheless, that a defect in one series is
+attended by a corresponding imperfection in adjoining ones. Thus
+trimerous fuchsias and tetramerous jasmines may frequently be met with,
+and Turpin describes a tetramerous flower of <i>Cob&aelig;a scandens</i>. Perhaps
+monocotyledonous plants are more subject to this numerical reduction of
+the parts of several verticils than are other flowering plants. Thus, in
+both <i>Lilium lancifolium</i> and <i>L. auratum</i> the writer has frequently met
+with pentamerous flowers. In <i>Convallaria maialis</i> a like deviation not
+unfrequently occurs.<a name="FNanchor_474_474" id="FNanchor_474_474"></a><a href="#Footnote_474_474" class="fnanchor">[474]</a> M. Delavaud has recorded a similar occurrence
+in a tulip.<a name="FNanchor_475_475" id="FNanchor_475_475"></a><a href="#Footnote_475_475" class="fnanchor">[475]</a></p>
+
+<p>Dimerous crocuses may also sometimes be met with. In one flower of this
+nature the segments of the perianth were arranged in decussating pairs,
+and the<span class='pagenum'><a name="Page_401" id="Page_401">[Pg 401]</a></span> four stamens were united by their filaments so as to form two
+pairs.</p>
+
+<p>M. Fournier mentions something of the same kind in the flower of an
+<i>Iris</i>.<a name="FNanchor_476_476" id="FNanchor_476_476"></a><a href="#Footnote_476_476" class="fnanchor">[476]</a></p>
+
+<p>Orchids seem peculiarly liable to the decrease in the number of their
+floral organs. Prillieux<a name="FNanchor_477_477" id="FNanchor_477_477"></a><a href="#Footnote_477_477" class="fnanchor">[477]</a> mentions a flower of <i>Cattleya
+amethystina</i> wherein each whorl of the perianth consisted of two
+opposite segments.</p>
+
+<p>The same observer has put on record instances of a similar kind in
+<i>Epidendrum Stamfordianum</i>. In one flower of the last-named species the
+perianth consisted of one sepal only, and one lip-like petal placed
+opposite to it.<a name="FNanchor_478_478" id="FNanchor_478_478"></a><a href="#Footnote_478_478" class="fnanchor">[478]</a> Morren<a name="FNanchor_479_479" id="FNanchor_479_479"></a><a href="#Footnote_479_479" class="fnanchor">[479]</a> describes a flower of <i>Cypripedium
+insigne</i>, in which there were two sepals and two petals. Of a similar
+character was the flower found by Mr. J. A. Paine, and described in the
+following terms by Professor Asa Gray in the 'American Journal of
+Science,' July, 1866:&mdash;"The plant" (<i>Cypripedium candidum</i>) "bears two
+flowers: the axillary one is normal; the terminal one exhibits the
+following peculiarities. The lower part of the bract forms a sheath
+which encloses the ovary. The labellum is wanting; and there are two
+sterile stamens, the supernumerary one being opposite the other, <i>i.e.</i>
+on the side of the style where the labellum belongs. Accordingly the
+first impression would be that the labellum is here transformed into a
+sterile stamen. The latter, however, agrees with the normal sterile
+stamen in its insertion as well as in shape, being equally adnate to the
+base of the style. Moreover, the anteposed sepal is exactly like the
+other, has a good midrib and an entire point. As the two sterile stamens
+are anteposed to the two sepals, so are the two fertile stamens to the
+two petals, and the latter are adnate to the style a little higher than
+the former. The style is longer than usual, is straight and erect; the
+broad, disciform stigma therefore<span class='pagenum'><a name="Page_402" id="Page_402">[Pg 402]</a></span> faces upwards; it is oval and
+symmetrical, and a light groove across its middle shows it to be
+dimerous. The placent&aelig;, accordingly, are only two. The groove on the
+stigma and the placent&aelig; are in line with the fertile stamens.</p>
+
+<p>Here, therefore, is a symmetrical and complete, regular, but dimerous
+orchideous flower, the first verticil of stamens not antheriferous, the
+second antheriferous, the carpels alternate with these; and here we have
+clear (and perhaps the first direct) demonstration that the orchideous
+type of flower has two stamineal verticils, as Brown always insisted."</p>

+</div>
+
+<p>Dr. Moore, of Glasnevin, kindly forwarded to the writer a flower of
+<i>Calanthe vestita</i> (fig. 198), in which there were two sepals only,
+anterior and posterior, and two petals at right angles to the two
+sepals. The lip was entirely wanting, but the column and ovary were<span class='pagenum'><a name="Page_403" id="Page_403">[Pg 403]</a></span> in
+their usual condition. In <i>Odontoglossum Alexandr&aelig;</i> a similar reduction
+of parts has been observed by the author (fig. 199).</p>
+
+<p>It is curious to observe in these flowers how precisely one sepal
+occupies the position of the labellum, and how the lateral petals are
+displaced from the position they usually occupy, so as to form a regular
+flower, the segments of which decussate, thus giving rise to a species
+of regular peloria.</p>
+
+<p>The genus <i>M&aelig;lenia</i> was established on a malformed flower of <i>Orchis</i> of
+similar character to those above mentioned.</p>
+
+
+
+<p><b>Meiotaxy of the calyx.</b>&mdash;As already mentioned, this term is here employed
+to denote those illustrations in which entire whorls are suppressed.
+Complete deficiency of the calyx in a dichlamydeous flower seems seldom
+or ever to occur; the nearest approach to it would be in those cases
+where the calyx is, as it is termed, "obsolete," but here it is chiefly
+the limb of the calyx which is atrophied, the lower portion being more
+or less adherent to the ovary. In what are termed monochlamydeous
+flowers both calyx and corolla are wanting, as in <i>Salicine&aelig;</i> and many
+other orders.</p>
+
+
+
+<p><b>Meiotaxy of the corolla.</b>&mdash;Deficiency of the entire corolla occurs in
+conjunction with similar reductions in other organs, or as an isolated
+phenomenon in the many apetalous varieties of plants recorded in books.
+Deficiency of the corolla was observed in <i>Campanula perfoliata</i> and
+<i>Ruellia clandestina</i> by Linn&eacute;, who calls such blooms <i>flores
+mutilati</i>.<a name="FNanchor_480_480" id="FNanchor_480_480"></a><a href="#Footnote_480_480" class="fnanchor">[480]</a> Drs. Hooker and Thomson relate a similar occurrence in
+<i>Campanula canescens</i> and <i>C. colorata</i>. Some plants seem as a normal
+occurrence to produce flowers of different construction, and are hence
+termed dimorphic, as in many <i>Malpighiace&aelig;</i>, <i>Violace&aelig;</i>, <i>Oxalidace&aelig;</i>,
+in some of the flowers of which the petals are altogether wanting, while
+in others the<span class='pagenum'><a name="Page_404" id="Page_404">[Pg 404]</a></span> corolla is developed as usual. This deficiency of the
+corolla is frequently, but not invariably, associated with an increased
+fertility. Thus, in some violets the flowers produced in summer, and in
+which the petals are either entirely suppressed or are more or less
+atrophied, are always fertile, while the blossoms developed in spring,
+and in which the petals are always present, are much less fertile. In
+<i>Oxalis Acetosella</i> there are two forms of flower, the one with, the
+other without, petals, but both seem equally fertile. Linn&eacute; remarks that
+many plants which, in warm latitudes, produce a corolla, do not do so
+when grown in colder climates. Thus, certain species of <i>Helianthemum</i>
+are apetalous in Lapland. In the Pyrenees, according to Bentham, the
+flowers of <i>Ajuga iva</i> are constantly deprived of their corolla.<a name="FNanchor_481_481" id="FNanchor_481_481"></a><a href="#Footnote_481_481" class="fnanchor">[481]</a></p>

+
+<p><b>Meiotaxy of the andr&oelig;cium.</b>&mdash;Complete suppression of the stamens
+occurs normally in the female flowers of unisexual plants, and, as an
+accidental occurrence, is not very uncommon. <i>Erica Tetralix</i> is one of
+the plants in which this is said to happen. The variety <i>anandra</i> is
+said to have been known in France since 1635. Cornuti speaks of it in
+his 'Enchiridion.' In 1860 M. du Parquet discovered it in peaty woods
+near Nangis (Seine et Marne).</p>
+
+<p>Many <i>Umbellifer&aelig;</i>, such as <i>Trinia vulgaris</i>, present a like
+deficiency, while it is of common occurrence among <i>Rosace&aelig;</i> and
+<i>Pomace&aelig;</i>. In the latter group the St. Valery apple, so often referred
+to, is an illustration. To obtain fruits from this variety it is
+necessary to apply pollen from another flower, a proceeding made the
+occasion of festivity and rejoicing by the villagers in some parts of
+France. In some of the <i>Artemisias</i>, especially in <i>Artemisia
+Tournefortiana</i>, all the florets have been noticed to be female, owing
+to the suppression of the stamens, and this suppression is associated
+with a change in the form of florets.<a name="FNanchor_482_482" id="FNanchor_482_482"></a><a href="#Footnote_482_482" class="fnanchor">[482]</a> Mr. Moggridge has
+communicated to the author flowers of <i>Thymus Serpyllum</i> from a plant in
+which all the stamens were deficient, the flower being otherwise normal.</p>
+
+<p>M. Dupont has given a list of nineteen species of <i>Chenopodiace&aelig;</i> in
+which female flowers are occasionally produced, owing to the entire
+suppression of the staminal whorl.<a name="FNanchor_483_483" id="FNanchor_483_483"></a><a href="#Footnote_483_483" class="fnanchor">[483]</a></p>
+
+<p>Flowers the subjects either of regular or irregular peloria, <i>q. v.</i>,
+are often destitute of some or all their stamens, <i>e.g.</i> <i>Calceolaria</i>,
+<i>Linaria</i>, <i>Viola</i>, &amp;c., while in cases of synanthy suppression of some
+of the parts of the flower, and specially of the stamens, is of very
+common occurrence.</p>
+
+<p>Suppression of the andr&oelig;cium as a teratological occurrence has been
+most frequently noticed in the<span class='pagenum'><a name="Page_406" id="Page_406">[Pg 406]</a></span> following plants, omitting members of
+those families whose floral construction is normally incomplete in the
+majority of instances, and exclusive also of cases of substitution. See

+<p><b>Meiotaxy of the gyn&oelig;cium.</b>&mdash;Complete suppression of the pistil is of
+more frequent occurrence than that of the stamens, hence more flowers
+become accidentally unisexual by suppression of the pistil than by
+deficiency of the stamens.</p>
+
+<p>In many <i>Umbellifer&aelig;</i>, e.g. <i>Torilis Anthriscus</i>, <i>Cicuta virosa</i>, the
+central flowers are often male, owing to the suppression of the pistil.
+In many double flowers, owing to the excessive multiplication of
+petaloid stamens, the pistil is suppressed, in which cases it often
+happens that the flower is depressed in the centre, as in some garden
+varieties of <i>Ranunculus</i>. Schlechtendal, in describing a flower of
+<i>Colchicum autumnale</i>, in which the perianth was virescent, says that,
+although the stamens were present, the pistil was absent.</p>
+
+<p>In proliferous flowers the pistil is often completely defective, its
+place being occupied by the adventitious bud or axis.</p>
+
+<p>As in other cases of like nature, suppression of the pistil is very
+frequently consequent on fusion of flowers or other changes. Thus Morren
+relates an instance of synanthy in the flowers of <i>Torenia scabra</i>,
+accompanied by resorption or disappearance of some parts<span class='pagenum'><a name="Page_407" id="Page_407">[Pg 407]</a></span> and spiral
+torsion of others. The pistil was entirely absent in this instance.<a name="FNanchor_484_484" id="FNanchor_484_484"></a><a href="#Footnote_484_484" class="fnanchor">[484]</a></p>
+
+<p>M. Gaetano Licopoli places on record an instance where the petals and
+carpels of <i>Melianthus major</i> were suppressed.<a name="FNanchor_485_485" id="FNanchor_485_485"></a><a href="#Footnote_485_485" class="fnanchor">[485]</a></p>
+
+<p>On the whole, the pistil seems less subject to changes of this character
+than the andr&oelig;cium.</p>
+
+<p>Suppression of the pistil has been most frequently recorded in flowers
+(normally bisexual) of&mdash;</p>

+
+<p><b>Suppression of ovules,&mdash;abortion of seeds.</b>&mdash;The two cases are taken
+together, as the effects are similar, though it must be remembered that
+in the one case the ovules at any rate have been formed, but their
+development has been arrested, while in the other they have never
+existed. The precise cause that has determined the absence of seed
+cannot in all cases be ascertained in the adult condition, hence it is
+convenient to treat the two phenomena under one head.</p>
+
+<p>Many plants in other than their native climates either produce no fruit
+at all, or the fruits that are produced are destitute of seed, <i>e.g.</i>
+<i>Musa</i>, <i>Artocarpus</i>, &amp;c. Some of the cultivated varieties of the grape
+and of the berberry produce no seeds.</p>
+
+<p>Suppression or abortion of the seed is frequently associated with the
+excessive development either in size or number of other portions of the
+plant, or with an altered condition, as when carpels become foliaceous
+and their margins detached. Hybridisation and cross fertilisation are
+also well-known agents in diminishing the number and size of seeds.</p><p><span class='pagenum'><a name="Page_408" id="Page_408">[Pg 408]</a></span></p>
+
+
+
+<p><b>Meiotaxy of the parts of the flower in general.</b>&mdash;In the preceding
+sections suppression has been considered as it affected individual
+members of a whorl or separate whorls. It rarely happens, however, that
+the suppression is limited in this way. More generally several of the
+parts of the flower are simultaneously affected in the same manner.</p>
+
+<p>A few illustrations are all that is necessary to give as to this point.</p>
+
+<p>One of the most familiar instances is that of the cauliflower or
+broccoli, where the common flower-stalk is inordinately thickened and
+fleshy, while the corolla and inner parts of the flower are usually
+entirely suppressed; the four sepals can, however, generally be
+detected.</p>
+
+<p>Maximowicz describes a <i>Stellaria</i> (<i>Kraschenikovia</i>) in which the upper
+flowers are male only, while the lower ones, which ultimately become
+buried in the soil, have neither petals, stamens, nor styles, but the
+walls of the capsule are fleshy, and enclose numerous seeds.<a name="FNanchor_486_486" id="FNanchor_486_486"></a><a href="#Footnote_486_486" class="fnanchor">[486]</a></p>
+
+<p>Kirschleger<a name="FNanchor_487_487" id="FNanchor_487_487"></a><a href="#Footnote_487_487" class="fnanchor">[487]</a> mentions a variety of <i>Lonicera Caprifolium</i>, which was
+not only destitute of petals but of stamens also.</p>
+
+<p>In some species of <i>Muscari</i> and <i>Bellevalia</i> the uppermost flowers of
+the raceme show more or less complete suppression of almost all the part
+of which the flower normally consists. In those cases where an imperfect
+perianth exists, but in which the stamens and pistils are entirely
+suppressed, Morren applies the term Cenanthy, <span class="greek" title="[Greek: kenos]">&#954;&#949;&#957;&#959;&#962;</span>, empty.</p>
+
+
+
+<p><b>Complete suppression of the flower.</b>&mdash;It is not necessary in this place
+to allude to that deficient production of flowers characteristic of what
+is termed by gardeners a "sky bloomer." In such plants often the
+requisite conditions are not complied with, and the skill of the<span class='pagenum'><a name="Page_409" id="Page_409">[Pg 409]</a></span>
+gardener is shown in his attempt to discover and allow the plant to
+avail itself of the necessary requirements. We need here only allude to
+those instances in which provision is made for the production of
+flowers, and yet they are not produced. A good illustration of this is
+afforded by the feather-hyacinth, <i>Hyacinthus comosus</i>, in which the
+flowers are almost entirely suppressed, while the pedicels are
+inordinately increased in number, and their colour heightened. Something
+similar occurs in several allied species, and in <i>Bowiea volubilis</i>. The
+wig plant (<i>Rhus Cotinus</i>) affords another illustration of the same
+thing. Some tendrils also owe their appearance to the absence of
+flowers, being modified peduncles; proofs of this may frequently be met
+with in the case of the vine.</p>
+
+<p>In <i>Lamium album</i> I have seen one of the verticillasters on one side of
+the stem completely wanting, the adjacent leaf being, however, as fully
+formed as usual.</p>
+
+
+
+<p><b>General remarks on suppression.</b>&mdash;On comparing together the various
+whorls of the flower in reference to suppression, and, it may be added,
+to atrophy, we find that these phenomena occur most rarely in the calyx,
+more frequently in the corolla, and very often in the sexual organs and
+seeds; hence it would seem as if the uppermost and most central organs,
+those most subject to pressure and latest in date of
+development&mdash;formed, that is, when the formative energies of the plant
+are most liable to be exhausted&mdash;are the most prone to be suppressed or
+arrested in their development. When the plants in which these
+occurrences happen most frequently are compared together, it may be seen
+that partial or entire suppression of the floral envelopes, calyx, and
+corolla, is far more commonly met with in the polypetalous and
+hypogynous groups than in the gamopetalous or epigynous series.</p>
+
+<p>The orders in which suppression (speaking generally) occurs most often
+as a teratological occurrence are the<span class='pagenum'><a name="Page_410" id="Page_410">[Pg 410]</a></span> following:&mdash;<i>Ranunculace&aelig;</i>,
+<i>Crucifer&aelig;</i>, <i>Caryophyllace&aelig;</i>, <i>Violace&aelig;</i>, <i>Leguminos&aelig;</i>, <i>Onagrace&aelig;</i>,
+<i>Jasminace&aelig;</i>, <i>Orchidace&aelig;</i>. It will be observed that these are all
+orders wherein suppression of the whole or part of the outer floral
+whorls takes place in certain genera as a constant occurrence.</p>
+
+<p>Again, it may be remarked that many of these orders show a tendency
+towards a regular diminution of the assumed normal number of their
+parts; thus, among <i>Onagrace&aelig;</i>, <i>Circeia</i> and <i>Lopezia</i> may be referred
+to, the former normally dimerous, the latter having only one perfect
+petal. So in fuchsias, a very common deviation consists in a trimerous
+and rarely a dimerous symmetry of the flower.</p>
+
+<p>Although, if the absolute number of genera or orders be counted, there
+appears to be little difference in the frequency of the occurrence of
+suppression in irregular flowers as contrasted with regular flowers, yet
+if the individual instances could be counted in the two groups
+respectively it would be found that suppression is more common among
+irregular than in regular flowers. Thus, the number of individual
+instances of flowers in which the perianth is defective is comparatively
+large among <i>Violace&aelig;</i>, <i>Leguminos&aelig;</i>, and <i>Orchidace&aelig;</i>. This statement
+hardly admits of precise statistical proof; still, it is believed that
+any observer who pays attention to the subject must come to the same
+conclusion. This is but another illustration of the fact that conditions
+which are abnormal in one plant constitute the natural arrangement in
+others.</p>
+
+<p>As to the suppressions that occur in the case of the sexual organs, and
+the relations they bear to dimorphism, diclinism, &amp;c., but little stress
+has been laid on them in this place, because their chief interest is in
+a physiological point of view, and is treated of in the writings of
+Mohl, Sprengel, Darwin, Hildebrand, and others. All that need be said
+here is, that teratology affords very numerous illustrations of those
+intermediate conditions which are also found, under<span class='pagenum'><a name="Page_411" id="Page_411">[Pg 411]</a></span> natural
+circumstances, between the absolutely unisexual flowers, male or female,
+and the structurally hermaphrodite ones. Rudimentary stamens or pistils
+are of very common occurrence in monstrous flowers. See Chapter on
+Heterogamy, &amp;c.</p>

+
+DEVIATIONS FROM THE ORDINARY SIZE AND CONSISTENCE OF ORGANS.</h2>
+
+
+<p>In the animal kingdom the entire adult organism, as well as each of its
+separate parts, has certain dimensions, beyond which, under ordinary
+circumstances, it does not pass, either in the one direction or the
+other. It may not be easy or possible to state what the limits are, but,
+practically, this inability to frame a precise limitation is productive
+of no inconvenience. It is universally admitted that a certain animal
+attains such and such dimensions, and that one organ has a certain
+proportionate size as contrasted with another. The same rules hold good
+in the case of plants, though in them it is vastly more difficult to
+ascertain what may be called the normal dimensions or proportions.
+Nevertheless observation and experience soon show what may be termed the
+average size of each plant, and any disproportion between the several
+organs is speedily detected.</p>
+
+<p>When there is a general reduction in size throughout all the organs of a
+plant, or throughout all the nutritive organs, stem, leaves, &amp;c., and
+the several portions participate in this diminished size, we have what
+are generally termed "dwarf varieties," dwarf in comparison, that is,
+with the ordinary condition of the plants; on the other hand, if the
+entire plant, or, at least, if the<span class='pagenum'><a name="Page_414" id="Page_414">[Pg 414]</a></span> whole of one set of organs be
+increased in size beyond the recognised average, we have large
+varieties, often qualified by such terms as <i>macrophylla</i>, <i>longifolia</i>,
+<i>macrantha</i>, &amp;c. &amp;c. In all these cases either the entire plant or whole
+series of organs are alike increased or diminished beyond average
+limits; and such variations are often very constant, and are transmitted
+by hereditary transmission. It may be supposed that such deviations may
+have originated, in the first instance, either from excessive use, or
+from disuse, or from the agency of certain conditions promoting or
+checking growth, as the case may be; but whether or no, it is certain
+that these variations often persist under different conditions, and that
+they often retain their distinctive characters side by side with plants
+presenting the normal average dimensions. In other cases the variations
+in size are of a less general character, and affect certain organs of a
+whorl in a relative manner, as, for instance, in the case of didynamous
+or tetradynamous stamens, where two or four stamens are longer than
+their fellows, the long or short stamens and styles of di- and
+tri-morphic flowers, &amp;c. These differences are sometimes connected with
+the development of parts in succession, and not simultaneously.</p>
+
+<p>Teratological deviations of size differ from those of which mention has
+just been made chiefly in this, that they are more limited in their
+manifestations. It is not, as a rule, the whole plant, or the whole
+series of nutritive or of reproductive organs, that are affected, but it
+is certain parts only; the alteration in size is more a relative change
+than an absolute one.</p>
+
+<p>For convenience sake the teratological alterations of size may be
+divided into those which are the result of<span class='pagenum'><a name="Page_415" id="Page_415">[Pg 415]</a></span> increased growth and those
+which arise from diminished action. It will be seen, therefore, that in
+these instances it is the bulk of the organs that is increased, not
+their number; moreover, their development or metamorphosis is not
+necessarily altered. In connection with increased size an alteration of
+consistence is so frequent that the two phenomena are here taken
+together. It will be borne in mind that the changes of consistence from
+membranous to succulent or woody are very frequent in the ordinary
+course of development. They may also occur as accidental phenomena, or
+the normal conditions of any particular flower or fruit may be exactly
+reversed, the usually succulent fruit becoming dry and capsular, and so
+forth.</p>

+<h3><a name="PART_Id" id="PART_Id"></a>PART I.<br />
+
+HYPERTROPHY.</h3>
+
+
+<p>The term hypertrophy may serve as a general one to comprise all the
+instances of excessive growth and increased size of organs, whether the
+increase be general or in one direction merely. General hypertrophy is
+more a variation than a deformity, unless indeed it be caused by insect
+puncture or the presence of a fungus, in which case the excessive size
+results from a diseased condition. For our present purpose hypertrophy
+may be considered as it affects the axile or the foliar organs, and also
+according to the way in which the increased size is manifested, as by
+increased thickness or swelling&mdash;intumescence, or by augmented
+length-elongation, by expansion or flattening, or, lastly, by the
+formation of excrescences or outgrowths, which may be classed under the
+head of luxuriance or enation.</p>
+
+<p>As size must be considered in this place relatively, it is not possible
+to lay down any precise line separating what are considered to be the
+normal dimensions from those which are abnormal.</p>
+
+<p>In practice no inconvenience will be found to accrue from this inability
+to establish a fixed rule, and we may say that an hypertrophied organ is
+one which, from some cause or other, attains dimensions which are not
+habitual to the plant in its usual, healthy, well-formed state.</p>
+
+<p>It will be seen that under this general head of hypertrophy, increase of
+size, however brought about, is included; thus, not only increase in
+length, but also in thickness; alterations of substance or consistence,
+no less than of dimensions, are here grouped together.<span class='pagenum'><a name="Page_417" id="Page_417">[Pg 417]</a></span> The alterations
+of consistence resulting from an inordinate development of cellular,
+fibrous, or ligneous tissue, are, of course, strictly homologous with
+the similar changes which occur, under ordinary circumstances, during
+the ripening of fruits or otherwise.</p>
+
+<p>Hypertrophy, whatever form it may assume, may be so slight as not
+perceptibly to interfere with the functions of the part affected, or it
+may exist to such an extent as to impair the due exercise of its office.
+It may affect any or all parts of the plant, and is generally coexistent
+with, if not actually dependent on, some other malformation. Thus, the
+inordinate growth of some parts is most generally attended by deficiency
+in the size and number of others, as in the peripheral florets of
+<i>Viburnum</i> or <i>Hydrangea</i>, where the corollas are relatively very large,
+and the stamens and pistils abortive.</p>
+
+

+
+<h4><a name="CHAPTER_Ij" id="CHAPTER_Ij"></a>CHAPTER I.<br />
+
+ENLARGEMENT.</h4>
+
+
+<p>A swollen or thickened condition (<i>renflement</i>) is usually the result of
+a disproportionate formation of the cellular tissue as contrasted with
+the woody framework of the plant. We see marked instances of it in
+cultivated carrots and turnips, the normal condition of the roots or
+root-stocks in these plants being one of considerable hardness and
+toughness, and their form slender, tapering, and more or less branched.</p>
+
+<p>The disproportionate development of cellular tissue is also seen in
+tubers and bulbs, and in the swollen stems of such plants as
+<i>Echinocactus</i>, <i>Adenium obesum</i>, some species of <i>Vitis</i>, &amp;c. So, too,
+the upper portion of the flower-stalk occasionally becomes much
+dilated,<span class='pagenum'><a name="Page_418" id="Page_418">[Pg 418]</a></span> so as ultimately to form a portion of the fruit. But it is not
+necessary to give farther illustrations of this common tendency in some
+organs to become hypertrophied. As a result of injury from insects or
+fungi, galls and excrescences of various kinds are very common, but
+their consideration lies beyond the scope of the present work.</p>

+
+<p><b>Enlargement of axile organs.</b>&mdash;All the species of <i>Pelargonium</i>,
+<i>Geranium</i>, <i>Mirabilis,</i> as well as those of <i>Caryophylle&aelig;</i> and other
+orders, have tumid nodes as a normal occurrence. In the genus
+<i>Pelargonium</i> this swelling is sometimes not confined to the nodes, but<span class='pagenum'><a name="Page_419" id="Page_419">[Pg 419]</a></span>
+extends to the interspaces between them, <i>e.g.</i> <i>P. spinosum</i>. This
+condition, which happens as a natural feature in the species just named,
+may also occur as an exceptional thing in others. The author is indebted
+to Dr. Sankey for a branch of <i>Pelargonium</i> which was thus thickened,
+the remaining branches not being in any way affected. The leaves on the
+swollen branch were smaller than the others, and their stalks more
+flattened. There was, in this instance, no trace of fungus or insect to
+account for the swelling of a single branch, which might, therefore, be
+due to bud-variation, perhaps to reversion to some ancestral form. The
+repeated cross fertilisations to which Pelargoniums have been subjected
+render this hypothesis not an improbable one.</p>
+
+<p>As an accompaniment to a spiral torsion of the woody fibres, this
+distension of the stem is frequently met with, as in <i>Valeriana</i>,
+<i>Dipsacus,</i> &amp;c. (See Spiral Torsion.)</p>
+
+
+
+<p><b>Knaurs.</b>&mdash;On certain trees, such as the oak, the hornbeam, some species
+of <i>Crat&aelig;gus</i>, &amp;c., hard woody lumps may occasionally be seen
+projecting, varying greatly in size, from that of a pea to that of a
+cocoa-nut. They are covered with bark, and consist in the interior of
+very hard layers of wood disposed irregularly, so as to form objects of
+beauty for cabinet-makers' purposes. From the frequent presence of small
+atrophied leaf-buds on their surface, it would seem as if the structures
+in question were shortened branches, in which the woody layers had
+become inordinately developed, as if by compensation for the curtailment
+in length.<a name="FNanchor_488_488" id="FNanchor_488_488"></a><a href="#Footnote_488_488" class="fnanchor">[488]</a> The cause of their formation is not known, but it has
+been ascertained that they are not due to insect agency. Knaurs may
+occasionally be used for purposes of propagation, as in the case of<span class='pagenum'><a name="Page_420" id="Page_420">[Pg 420]</a></span> the
+"uovoli of the olive" and the "burrs" that are formed on some varieties
+of apple, from which both roots and leaf-shoots are produced in
+abundance.</p>
+
+<p>A distinction must be drawn between those instances in which the
+swelling is solid throughout from the excessive formation of cellular
+tissue, and those wherein it is hollow from the more rapid growth of the
+outer as contrasted with the inner portions. These latter cases might be
+classed under the head of distension.</p>

+these fruits was completely superior, the succulent portion of the fruit
+being made up of the dilated extremity of the peduncle, and possibly in
+part of the base of the calyx. The general appearance was thus that of a
+crab-apple. There was no stone in the interior, but simply a rudimentary
+kernel or seed.<a name="FNanchor_493_493" id="FNanchor_493_493"></a><a href="#Footnote_493_493" class="fnanchor">[493]</a></p>

+<p>Moquin-Tandon records an instance in which the stamens of each

+
+<p>In this place may also be mentioned the hypertrophied condition of the
+placenta observed by Alphonse de Candolle in a species of <i>Solanum</i>, and
+also in a species of <i>Melastoma</i>. Not only was the placenta unusually
+large in these flowers, but it also protruded beyond the ovary.<a name="FNanchor_495_495" id="FNanchor_495_495"></a><a href="#Footnote_495_495" class="fnanchor">[495]</a> A
+similar state of things in <i>Lobelia</i> and <i>Cuphea</i> has already been

+
+<p>The following singular growth in a tomato is described<span class='pagenum'><a name="Page_425" id="Page_425">[Pg 425]</a></span> by the Rev. M.
+J. Berkeley in the 'Gardeners' Chronicle' for 1866, p. 1217, and appears
+to have been an extension of the placenta:&mdash;"On the first glance it
+seemed as if an unusually large grape-stone had accidentally fallen on
+the upper surface of the fruit, and was attached by the narrow base. The
+process was, however, five lines long, and much narrowed below, besides
+which, though it was pale green above, the base was coral-red, like the
+tomato itself. It grew on a narrow and shallow crack on the surface of
+the fruit, and was found below to communicate directly with a
+fibro-vascular bundle, which entered into the composition of a portion
+of the placenta. On making a vertical section, instead of being
+succulent, as I expected, it was white and spongy within, with several
+lacunae, and one or two irregular fibro-vascular bundles, with highly
+developed spiral vessels threading the centre. These vessels, moreover,
+were tinged with brown, as in many cases of diseased tissues. There was
+not the slightest appearance of placent&aelig; or anything indicating an
+abortive fruit. On closer examination the cuticle was found to consist
+of thick-walled cells, exactly like those of the tomato, while the
+spongy mass consisted of a similar tissue to the fleshy portion of the
+fruit, but with far less wrinkled walls, and more indistinct
+intercellular spaces. The most striking point, however, was the immense
+quantity of very irregular and unequal starch-grains with which they
+were gorged, which gave a peculiar sparkling appearance to them when
+seen <i>en masse</i>. I am inclined to regard the body rather as an abortive
+axis than an undeveloped fruit. In almost all, if not all, these cases
+of abnormal growth, whether from leaves, petioles, fruit, or other
+portions of the plant, we find an immediate connection with one or more
+spiral vessels, which if not existent at first are developed sooner or
+later. In the present case the connection of the fibro-vascular tissue
+of the fruit and abnormal growth was plain enough, but whether it
+existed when the body was<span class='pagenum'><a name="Page_426" id="Page_426">[Pg 426]</a></span> first given off I am unable to say, as it was
+fully developed when the fruit was brought to me."</p>
+
+
+
+<p><b>Enlargement of the leaves.</b>&mdash;Increase in the size or substance of leaves
+takes places in several ways, and affects the whole or only certain
+portions of them. The simplest form of this malformation is met with in
+our cabbages, which, by the art of the gardener, have been made to
+produce leaves of greater size and thickness than those which are
+developed in the wild form. In such instances the whole substance of the
+leaf is increased in bulk, and the increase affects the fibrous
+framework of the leaves as well as the cellular portions, though the
+exaggerated development of the latter is out of proportion to that of
+the former.</p>
+
+<p>In some species of <i>Podocarpus</i> there may occasionally be seen at the
+base of the branchlets a dozen or more fleshy scales, of a rose colour,
+passing gradually into the ordinary leaves of the plant, and evidently
+analogous to the three fleshy confluent bracts which surround the ripe
+fruit.</p>
+
+<p>In other instances, while the fibrous framework of the leaf retains its
+usual degree of development, the cellular parenchyma is developed in
+excess, and, if the increase is so arranged that the number of
+superposed layers of the cellular tissue is not increased, or their
+thickness exaggerated, then we get such leaves as those of the "kail,"
+or of the "Savoys" leaves, which are technically called by descriptive
+botanists "folia bullata." In such leaves the disc of the leaf, rather
+than the margin, is increased and its surface is thrown up into little
+conical projections, which are hollow on the under side.</p>
+
+<p>But leaves may increase beyond their usual size without such grave
+alterations of form as those to which allusion has just been made. It is
+well known that if a tree be cut down and new shoots be sent out from
+the stump, the leaves formed on these shoots very often greatly exceed
+the ordinary ones in dimensions.<span class='pagenum'><a name="Page_427" id="Page_427">[Pg 427]</a></span> Such cases as this hardly come under
+the head of malformations. But where one part only of the leaf is
+excessively developed, the other portion remaining in its ordinary
+condition, there can be no hesitation in ranking the phenomenon as
+teratological.</p>
+
+<p>Thus, Moquin says that the median nerve may be prolonged beyond the
+blade of the leaf in the form of a short strap or ribbon-like
+excrescence, while, at other times, the lateral parts of the leaf are
+subjected to undue development. He refers to a case cited by
+Schlotterbec<a name="FNanchor_496_496" id="FNanchor_496_496"></a><a href="#Footnote_496_496" class="fnanchor">[496]</a> in which each side of the leaves of a yellow "violier"
+(wallflower) was dilated into a kind of projecting lobe on either side
+of the true apex of the leaf, thus rendering it in appearance
+three-lobed. M. Delavaud<a name="FNanchor_497_497" id="FNanchor_497_497"></a><a href="#Footnote_497_497" class="fnanchor">[497]</a> puts on record a case of hypertrophy in
+the leaves of the common elm, resulting in the formation of an
+additional lobe and a return to the tricostate type. A leaf so affected
+is stated to have presented the appearance of a fusion of two leaves.
+(See also Multiplication of leaves, p. 353.)</p>
+
+<p>The hypertrophied and coloured leaf of <i>Gesnera</i> occupying the place of
+the absent inflorescence has been previously alluded to under the head
+of displacement (p. 88).</p>
+
+<p>In some instances hypertrophy is the opposite of suppression; as in the
+case previously mentioned, where the stipule in the inflorescence of a
+pea, which is usually undeveloped and rudimentary, was developed in the
+form of a leafy cup or pitcher.</p>
+
+<p>Another instance of the development of parts usually suppressed, is
+afforded by the bud-scales of <i>Magnolia fuscata</i>, which may sometimes be
+found with small but perfect leaves projecting from them, the leaf in
+this case being the lamina which is ordinarily abortive, while the
+scales are the representatives of the stipules. This condition is said
+by Hooker and Thomson ('Flora Indica,' p. 73) to be constant in
+<i>Magnolia Campbelli</i>.</p><p><span class='pagenum'><a name="Page_428" id="Page_428">[Pg 428]</a></span></p>
+
+
+
+<p><b>Enlargement of the perianth, &amp;c.</b>&mdash;One or all the segments of the
+perianth may be subjected to hypertrophy; thus, the utricle of <i>Carex
+vulpina</i> may frequently be observed to attain four or five times its
+usual size, the contained ovary remaining unaffected. This condition is
+generally the result of insect puncture. The growth of parasitic fungi
+will produce a similar result, as is often seen in the common shepherd's
+purse, <i>Thlaspi bursa pastoris</i>, and other <i>Crucifer&aelig;</i>. The perianth of
+<i>Rumex aquaticus</i> has been also observed to be occasionally
+hypertrophied in conjunction with a similar condition of the pistil and
+with atrophy of the ovules.</p>
+
+<p>Moquin relates having found flowers of <i>Salsola Kali</i> and of
+<i>Chenopodium murale</i> in which some of the segments of the perianth were
+five or six times larger than they should be.</p>

+<p>The adjoining woodcut represents a singular condition of some cocoa-nuts
+in the Kew Museum, the<span class='pagenum'><a name="Page_429" id="Page_429">[Pg 429]</a></span> appearance of which is due apparently to an
+hypertrophied condition of the segments of the perianth, which have not
+only increased in length as the central nut has ripened, but have
+developed in their tissues that fibrous tissue which ordinarily is found
+in the pericarp only. This view of the structure of these nuts is borne
+out by the fact that, under normal circumstances, the base of the
+perianth contains a considerable amount of fibrous material. In the
+present case this has increased to such an extent that the fruit appears
+surrounded by a double husk, by an inner one as usual, and by an outer
+six-parted one.</p>
+
+<p>It will be remembered that in some of the <i>Cinchonace&aelig;</i>, e.g.
+<i>Muss&aelig;nda</i>, <i>Pinckneya</i>, <i>Calycophyllum</i>, one or more of the calycine
+lobes are normally dilated and petaloid, the others remaining small and
+comparatively inconspicuous. Inequality in size is, indeed, a common
+occurrence in the sepals of many natural orders&mdash;<i>Polygalace&aelig;</i>,
+<i>Leguminos&aelig;</i>, <i>Labiat&aelig;</i>, &amp;c. The flowers of a rose are mentioned by
+Moquin as having presented an enlargement of the calyx without any other
+alterations in form. Schlechtendal has noticed the same thing in
+<i>Papaver Rh&oelig;as</i>, Reichenbach in <i>Campanula persicifolia</i>, and A. de
+Candolle in <i>C. Rapunculus</i>. M. Brongniart also has recorded<a name="FNanchor_498_498" id="FNanchor_498_498"></a><a href="#Footnote_498_498" class="fnanchor">[498]</a> a
+remarkable variety of <i>Primula sinensis</i> cultivated in the Jardin des
+Plantes at Paris, wherein the calyx is enormously developed. MM.
+Fournier and Bonnet have described flowers of <i>Rubus</i> with hypertrophied
+calyx in conjunction with atrophy and virescence of the petals and other
+changes.<a name="FNanchor_499_499" id="FNanchor_499_499"></a><a href="#Footnote_499_499" class="fnanchor">[499]</a></p>
+
+<p>The corolla may be hypertrophied in some cases, though the change is
+more rare than in most other organs. Moquin-Tandon mentions as subject
+to this anomaly species of <i>Galeopsis</i>, <i>Prunella</i>, <i>Scabiosa</i>, and
+<i>Dipsacus</i>, and also mentions a remarkable variety of <i>Viola odorata</i>
+cultivated in the neighbourhood of<span class='pagenum'><a name="Page_430" id="Page_430">[Pg 430]</a></span> Toulouse. The same learned author
+also alludes to the so-called double Composites, viz. those in which the
+usually tubular florets of the disc assume the form and proportions of
+those of the ray, but these are hardly cases of hypertrophy.</p>
+
+
+
+<p><b>Enlargement of the andr&oelig;cium.</b>&mdash;Dunal<a name="FNanchor_500_500" id="FNanchor_500_500"></a><a href="#Footnote_500_500" class="fnanchor">[500]</a> alludes to a curious
+instance in a species of <i>Verbascum</i>, the lower flowers of which had
+hairy stamens as usual, but the filaments of the topmost flower were
+quite destitute of hairs, and dilated like a flat ribbon.</p>
+
+<p>Moquin relates having found in the neighbourhood of Toulouse a plant of
+<i>Solanum Dulcamara</i> in which all the upper flowers had two or three
+stamens of larger dimensions than the others. This happens habitually in
+<i>Solanum tridynamum</i> and <i>S. Amazonicum</i>, and to a less extent in <i>S.
+vespertilio</i> and <i>S. cornutum</i>; also in some species of <i>Hyoscyamus</i>.
+These cases show the close affinity between the <i>Solanace&aelig;</i> and the
+<i>Scrophulariace&aelig;</i>.</p>
+
+
+
+<p><b>Enlargement of the gyn&oelig;cium.</b>&mdash;In some flowers which have become
+accidentally female the pistil becomes unusually large, and even to such
+an extent as to prevent the passage of the pollen. Moquin remarks having
+seen this enlargement in the pistils of <i>Su&aelig;da fruticosa</i> and <i>Kochia
+scoparia</i>. The flowers of these Chenopods, under these circumstances,
+resemble the female flowers of some nettles. The styles of <i>Anemone</i> are
+also much enlarged as the result of cultivation, and from their petaloid
+appearance resemble those of the <i>Iris</i> (Goethe). MM. Seringe and
+Heyland<a name="FNanchor_501_501" id="FNanchor_501_501"></a><a href="#Footnote_501_501" class="fnanchor">[501]</a> have figured some anomalous flowers of <i>Diplotaxis
+tenuifolia</i> in which the pistil, more or less distended and deformed,
+was considerably elongated below, so that it seemed to be borne upon a
+long stalk, analogous to that of fruits of Capparids. Dr. Klinsman<a name="FNanchor_502_502" id="FNanchor_502_502"></a><a href="#Footnote_502_502" class="fnanchor">[502]</a>
+mentions an instance of a similar kind combined<span class='pagenum'><a name="Page_431" id="Page_431">[Pg 431]</a></span> with hypertrophy of the
+sepals and pistils; indeed, the alteration is not uncommon among
+Crucifers. <i>Pyrethrum inodorum</i> is very subject to hypertrophy. The
+styles of its radial florets become elongated without any other
+alteration; at the same time the small corollas become green, and show a
+tendency to assume a foliaceous condition. Sometimes the hypertrophy
+affects also the styles of the central florets, and these also become
+enlarged to double or treble their usual dimensions.</p>
+
+<p>Linn&eacute; has remarked that the ovary of <i>Tragopogon</i> sometimes assumes very
+large dimensions, as also does the pappus. He mentions a double-flowered
+variety, the ovaries of which become ten or twelve times larger than
+ordinary. M. Clos<a name="FNanchor_503_503" id="FNanchor_503_503"></a><a href="#Footnote_503_503" class="fnanchor">[503]</a> records an instance in <i>Rumex scutatus</i> wherein
+the pistil was hypertrophied or club-shaped, and open at the top, or in
+other cases funnel-shaped, three-lobed at the summit, each lobe
+terminated by a style. One of the most frequent causes tending to the
+hypertrophy of the pistil is attributable to the puncture of insects;
+thus, when the ovary of <i>Juncus articulatus</i> is thus punctured, it
+acquires a size two or three times larger than ordinary, becoming at the
+same time sterile.<a name="FNanchor_504_504" id="FNanchor_504_504"></a><a href="#Footnote_504_504" class="fnanchor">[504]</a></p>
+
+<p>Occasionally the enlargement may be due to a fusion or incorporation of
+other elements; thus, M. Lemaire describes an instance in which the
+style of <i>Sinningia purpurea</i> was much larger than ordinary, tubular,
+bearing three small lobes, and altogether bearing much resemblance to
+the column or "gynosteme" of Orchids. This appearance was due to the
+cohesion and intimate union of the styles with three abortive
+stamens.<a name="FNanchor_505_505" id="FNanchor_505_505"></a><a href="#Footnote_505_505" class="fnanchor">[505]</a></p>
+
+
+
+<p><b>Enlargement of the fruit.</b>&mdash;Most cultivated fruits are in a state of true
+hypertrophy. Girod de Chantrans, after many trials, succeeded in
+producing a peculiar variety<span class='pagenum'><a name="Page_432" id="Page_432">[Pg 432]</a></span> of pea with pods double the ordinary
+size.<a name="FNanchor_506_506" id="FNanchor_506_506"></a><a href="#Footnote_506_506" class="fnanchor">[506]</a> M. Clos<a name="FNanchor_507_507" id="FNanchor_507_507"></a><a href="#Footnote_507_507" class="fnanchor">[507]</a> mentions a case wherein the carpels of
+<i>Delphinium dictyocarpum</i> were hypertrophied. The change in size may or
+may not be attended by a difference in form; thus, in certain
+<i>Leguminos&aelig;</i>, as <i>Medicago lupulina</i>, <i>Melilotus leucantha</i>, the carpels
+are sometimes hypertrophied and elongated, so as to resemble a claw or
+hook.<a name="FNanchor_508_508" id="FNanchor_508_508"></a><a href="#Footnote_508_508" class="fnanchor">[508]</a></p>
+
+<p>The fruit of the common groundsel (<i>Senecio vulgaris</i>) is in its normal
+condition two or three times shorter than the involucre, and cylindrical
+for its whole length, but it frequently happens that the fruits become
+as long as the involucre itself, and taper from the base upwards, so as
+to become beaked. Under this head may also be mentioned the fleshy
+bulbils that are found in the capsules of <i>Crinum</i>, <i>Amaryllis</i>, and
+<i>Agave</i>. These are true seeds enormously dilated.<a name="FNanchor_509_509" id="FNanchor_509_509"></a><a href="#Footnote_509_509" class="fnanchor">[509]</a> In these seeds
+the outer coating becomes very thick and fleshy, and is traversed by
+spiral vessels.</p>
+
+<p>It is obvious that very important results in a practical point of view
+may be and have been arrived at by cultivators availing themselves of
+this tendency of plants to increase in dimensions under certain
+circumstances. It is needless to do more than refer to the many fruits,
+vegetables, and cereals, which have thus become enlarged and improved by
+careful selection and rearing.</p>
+
+
+
+<p><b>Alterations of consistence</b> often accompany changes in size. The change
+may be one whereby the tissues become unusually hardened, by the
+excessive formation of secondary woody deposits, or softer and more
+succulent than ordinary, from the formation of an inordinate amount of
+loose cellular tissue. Generally<span class='pagenum'><a name="Page_433" id="Page_433">[Pg 433]</a></span> speaking, the appearances presented in
+such cases are not sufficiently striking to demand notice other than as
+regards their size. One illustration, however, may be cited from its
+singularity. This was the case of a dahlia, in which the centre of the
+flower was occupied by a projecting knob as large as a walnut, brown in
+colour, and very hard in texture. This knob was nothing but the enlarged
+and indurated extremity of the common receptacle, destitute of the
+scales and florets which usually spring from it. No insect-puncture
+could be detected, and no other reason for this peculiarity could be
+ascertained.</p>

+
+ELONGATION.</h4>
+
+
+<p>The class of cases coming under this head are sufficiently indicated by
+the name. There are many instances of this phenomenon occurring under
+different conditions, which, though unusual, can hardly be called
+abnormal, such, for instance, as the great lengthening of roots in their
+search for water, the excessive elongation that takes place in plants
+when grown at a distance from the light, in their endeavour to attain to
+which they become, as gardeners phrase it, "drawn." A similar result is
+brought about in forests or plantations, where long spars are required,
+by allowing the trees to grow very close to each other, so as to prevent
+the lateral extension of the branches. When plants grow in running water
+their roots, stems, and sometimes their leaves, become excessively
+elongated, as in <i>Ranunculus fluitans</i>, the flower-stalks of <i>Valisneria
+spiralis</i>, &amp;c. These are cases of variation rather than of malformation,
+but are none the less curious, or sometimes perplexing; thus, Lapeyrouse
+described, in<span class='pagenum'><a name="Page_434" id="Page_434">[Pg 434]</a></span> his 'Supplement &agrave; la flore des Pyren&eacute;es,' p. 27, under
+the name <i>Potamogeton bifolium</i>, a plant which Mr. Bentham subsequently
+discovered to be nothing but a flowerless variety of <i>Vicia Faba</i>
+distorted by its growth in water.<a name="FNanchor_510_510" id="FNanchor_510_510"></a><a href="#Footnote_510_510" class="fnanchor">[510]</a></p>
+
+
+
+<p><b>Elongation of the root.</b>&mdash;This, as already remarked, is more often a
+variation than a malformation, and is usually due to the presence of
+water at a distance necessitating growth at the extremities of the root,
+or to the presence of some obstacle, such as a stone, to avoid which the
+root elongates till it has passed the obstruction. Occasionally in
+Crocus corms some of the fibrils may be met with much lengthened and
+thickened, and invested with a fleshy sheath. It is not certain,
+however, that these structures are roots; possibly, nay probably, they
+may be processes from the stem thrust downwards into the soil, similar
+to the formations already described in the tulip (p. 85, fig. 39).</p>
+
+
+
+<p><b>Elongation of the inflorescence.</b>&mdash;Under this heading it is necessary to
+consider lengthening of the common rachis in the case of an aggregate
+inflorescence, and lengthening of the individual flower-stalks, whether
+they be solitary or portions of a multiple inflorescence. The two
+phenomena may occur together, but they are quite as often independent
+one of the other. Thus, among <i>Umbellifer&aelig;</i> the umbels are occasionally
+met with supported on unusually long stalks, while the pedicels of the
+individual flowers may or not be increased in length; so also with some
+of the Composites, or the heads of flowers of some <i>Leguminos&aelig;</i>,
+<i>Trifolium repens</i>, &amp;c. &amp;c.</p>
+
+<p>Another illustration of the sort is that recorded by M. Fournier,
+wherein the usually umbellate inflorescence of <i>Pelargonium</i> was,
+through the lengthening of the main stalk, transformed into a raceme.
+Among Composites a similar change may sometimes be met with.</p><p><span class='pagenum'><a name="Page_435" id="Page_435">[Pg 435]</a></span></p>
+
+<p>MM. Clos and De Sch&ouml;nefeld have recorded the existence of a variety of
+the sweet chestnut (<i>Castanea</i>)in which the female catkins were as long,
+and bore nearly as many flowers, as the male spikes. This is stated to
+be of constant occurrence in some localities, and to be accompanied by a
+diminished size of the fruits. A similar elongation has been observed in
+the case of the walnut, catkins of which have been seen bearing thirty
+to thirty-five large nuts.<a name="FNanchor_511_511" id="FNanchor_511_511"></a><a href="#Footnote_511_511" class="fnanchor">[511]</a></p>
+
+<p>In the strobile of the hop, <i>Humulus Lupulus</i>, a like elongation may
+sometimes be met with, generally in association with a more or less
+leafy condition of some of the scales.</p>
+
+<p>Of a similar character, but complicated with extrusion or eversion of an
+ordinarily concave axis, is the fig described by Zuccarini,<a name="FNanchor_512_512" id="FNanchor_512_512"></a><a href="#Footnote_512_512" class="fnanchor">[512]</a> and
+from the appearances presented by which that author draws the inference
+that the peculiar appearance of the fig is due to the formation of a
+large number of small bracts blended together for the greater part of
+their length, and accompanied by the suppression of the internodes, and
+consequent shortening of the axis. In the monstrous fruit the axis is
+prolonged, and forms a kind of raceme or catkin, surrounded at the base
+by numerous bracts, as in many <i>Amentace&aelig;</i>. (<a href="#Page_204">See p. 204</a>, figs. 105,
+106.)</p>
+
+<p>A lengthening of the axis of the female strobiles of <i>Conifer&aelig;</i> is not
+of infrequent occurrence in <i>Cryptomeria japonica</i>, <i>Larie europ&aelig;a</i>,
+&amp;c., and this is usually associated, as has been before stated, with a
+leaf-like condition of the bracts, and sometimes even with the
+development of leaf-bearing shoots in place of the scales. (See under
+Prolification of Inflorescence and Phyllomorphy, and for references, p.
+115.)</p>
+
+
+
+<p><b>Elongation of the secondary flower-stalks.</b>&mdash;In the previous section the
+effect of elongation of the main rachis has been considered. A
+corresponding deviation occurs in<span class='pagenum'><a name="Page_436" id="Page_436">[Pg 436]</a></span> the peduncles or pedicels, and
+sometimes alters the general character of the inflorescence very
+considerably, converting a spike into a raceme, a raceme into a corymb,
+a capitulum into an umbel, and so forth. A few such cases may here be
+alluded to. Fig. 206 represents a specimen of <i>Ranunculus acris</i>, in
+which the lower and lateral flower-stalks were not only increased in
+number, but so much lengthened as to form a flat-topped inflorescence&mdash;a
+corymbose cyme. In many leguminous plants, as in <i>Trifolium repens</i>,
+<i>Lotus corniculatus</i>, &amp;c., what is usually a compact spike, or head<span class='pagenum'><a name="Page_437" id="Page_437">[Pg 437]</a></span> of
+flowers, becomes a raceme from the elongation of the pedicels. In
+<i>Umbellifer&aelig;</i> a similar change occurs, by virtue of which sometimes the
+umbels themselves, and at other times the florets, are raised on
+unusually long stalks, as in <i>Angelica Razoulzii</i>, <i>Carum Carui</i>,
+<i>Thysselinum palustre</i>.<a name="FNanchor_513_513" id="FNanchor_513_513"></a><a href="#Footnote_513_513" class="fnanchor">[513]</a> In <i>Composit&aelig;</i>, when affected by an
+analogous change, the capitulum assumes the appearance of a simple
+umbel, as in <i>Hypoch&aelig;ris radicata</i>, <i>Senecio vulgaris</i>, and other
+plants.</p>

+<p class="caption"> <span class="smcap">Fig.</span> 206.&mdash;Inflorescence of <i>Ranunculus acris</i>, with secondary peduncles lengthened.</p>
+</div>
+
+<p>In some of the double-flowered apples which have been previously alluded
+to, the flower-stalk is inordinately long when compared with the
+adjacent ones. Possibly in some of these cases the absence of the usual
+swelling of the upper part of the peduncle may be connected with its
+increased length. One of the most striking instances of lengthened
+flower-stalk occurred in an apple flower, wherein there was no swelling
+beneath the calyx, while the latter was represented by five perfect
+stalked leaves.</p>
+
+
+
+<p><b>Elongation of the leaves.</b>&mdash;In the case of water plants this change keeps
+pace with the corresponding growth of the stem, <i>e.g.</i> <i>Ranunculus
+fluitans</i>, and in terrestrial plants there are varieties termed
+longifoliar, from the unusual length of the leaves. A similar
+lengthening occurs in the involucral leaves of <i>Umbellifer&aelig;</i> and
+<i>Composit&aelig;</i>, changing very materially the general aspect of the
+inflorescence. Occasionally, also, the leaf-lobes of parsley (<i>Apium
+Petroselinum</i>) and other crested-leaved plants may be observed to lose
+their ordinary wavy form, and to be lengthened into flat riband-like
+segments, as shown in fig. 207.</p>
+
+<p>The only further illustrations that it is requisite to give of such
+changes in this place are those occurring in lobed or compounded leaves,
+which, from a lengthening of the midrib or central stalk, convert a
+digitate or palmate leaf into a pinnate one. In these instances<span class='pagenum'><a name="Page_438" id="Page_438">[Pg 438]</a></span> the
+lobes or leaflets become separated one from another by a kind of
+apostasis. This change may be frequently seen in the horse-chestnut,
+particularly in the young shoots formed after the trees have been pruned
+or pollarded. In the adjoining cut the intermediate stages between a
+palmate or digitate leaf to a pinnate one may be seen. The specimens
+from which the drawing was made were taken from the same tree at the
+same time.</p>

+
+
+
+<p><b>Elongation of the parts of the flower.</b>&mdash;The only circumstance that needs
+especial mention under this section is the great lengthening that
+sometimes takes place in<span class='pagenum'><a name="Page_439" id="Page_439">[Pg 439]</a></span> the carpels, sometimes as a result of injury
+from insects or fungus, at other times without assignable cause.</p>

+</div>
+
+<p>In the case of inferior ovaries this lengthening is, perhaps, even more
+common, as in <i>Umbellifer&aelig;</i>, <i>Composit&aelig;</i>, &amp;c. The common groundsel
+(<i>Senecio vulgaris</i>) is especially liable to this form of enlargement of
+the<span class='pagenum'><a name="Page_440" id="Page_440">[Pg 440]</a></span> pistil, either in association with a leafy condition of the pappus
+or without any such change.</p>
+
+
+
+<p><b>Elongation of the thalamus, placenta, &amp;c.</b>&mdash;In some plants, as in
+<i>Magnolia</i> or <i>Myosurus</i>, the thalamus becomes much elongated, and bears
+the carpels disposed spirally around it. A similar lengthening occurs in
+malformed flowers, usually in association with a similar change in the
+lower or outer part of the flower, by virtue of which the whorls become
+separated from each other (Apostasis). Elongation and protrusion of the

+some of these cases the elongated placenta has taken the form of a

+<p><b>Apostasis.</b>&mdash;Engelmann made use of this term to express the separation of
+parts one from another by the unusual elongation of the internodes.<a name="FNanchor_516_516" id="FNanchor_516_516"></a><a href="#Footnote_516_516" class="fnanchor">[516]</a>
+He drew a distinction between the separation of individual organs one
+from the other, and the corresponding displacement of whorls. The
+subject has already been, to a considerable degree, treated of in these
+pages under the head of dialysis, displacement, and prolification, and
+but little need here be added. With reference to the distance between
+one whorl and another, it will be remembered that, although in the
+majority of cases the floral whorls are packed closely together, yet in
+other instances the floral axis becomes elongated, and thus separates
+the whorls one from another, by structures such as the gynophores,
+androphores, &amp;c., of <i>Passiflore&aelig;</i>, <i>Caryophylle&aelig;</i>, <i>Capparide&aelig;</i>, &amp;c.
+&amp;c.</p>
+
+<p>A similar elongation of the thalamus, bringing about the separation of
+the floral whorls, or of their constituent parts, is very commonly met
+with in association with median prolification. Where the individual
+floral elements are thus thrown out of their usual verticillate
+arrangement, they naturally assume a spiral disposition,<span class='pagenum'><a name="Page_441" id="Page_441">[Pg 441]</a></span> and are, in
+some cases, united by their margins, so that a spiral sheet or tube is
+formed, surrounding the axis. This frequently occurs in double flowers
+of the Chinese primrose, <i>Primula sinensis</i>.</p>
+
+<p>Engelmann<a name="FNanchor_517_517" id="FNanchor_517_517"></a><a href="#Footnote_517_517" class="fnanchor">[517]</a> figures a case wherein the calyx of <i>Anagallis
+ph&oelig;nicea</i> was separated by a rather long internode from the corolla,
+and a like illustration in <i>Torilis Anthriscus</i>.</p>

+
+<p>A frequent change in Crucifers is due to the formation of a long stalk
+bearing the pod, and thus giving rise to the appearance met as a
+constant occurrence in Capparids.</p>
+
+<p>In <i>Trop&aelig;olum majus</i> a similar elevation of the pistil may occasionally
+be seen.</p>
+
+<p>The adjacent figure of a monstrous <i>Delphinium</i> taken from Cramer
+illustrates well the elongation of the floral axis and the apostasis of
+the carpels. In this instance the axis is terminated by a second flower
+(median prolification).</p>
+
+<p>One of the best-marked illustrations of these changes occurs in a
+permanent malformation of <i>Epilobium hirsutum</i>, specimens of which were
+originally obtained from the late Professor Henslow. The several floral
+parts are here, some virescent, others truly foliaceous, and each whorl
+is separated from its neighbour by a rather long internode. In <i>Fuchsia</i>
+and <i>Campanula</i> a like change may occasionally be observed.</p>
+
+<p>Engelmann, in addition to those previously mentioned, cites the
+following plants as having manifested this change:</p>
+
+<p><i>*Convallaria majalis!</i>, <i>*Tulipa Gesneriana!</i>, <i>Veronica Cham&aelig;drys</i>,
+<i>Orobanche gracilis</i>, <i>Solanum Lycopersicum</i>, <i>Gentiana campestris</i>,

+<i>Ranunculace&aelig;</i>. (See Dialysis, Median Prolification, &amp;c.)</p>
+
+<p>Apostasis of the sub-floral or involucral leaves is not of infrequent
+occurrence in malformations affecting <i>Composit&aelig;</i> and <i>Umbellifer&aelig;</i>. In
+the following genera it has been observed with especial
+frequency:&mdash;<i>Torilis Anthriscus</i>, <i>Eryngium</i>, <i>Athamanta Cervaria</i>,
+<i>Leontodon</i>, <i>Tragopogon pratense!</i>, <i>Wedelia perfoliata!</i> In garden

+
+ENATION.</h4>
+
+
+<p>Under the above heading are included certain forms arising from excess
+not of growth, but of development, and consisting in the formation of
+supplementary lobes or excrescences from various organs.</p>
+
+<p>The new formations are not due either to a repetition or to a partition
+of any organ, but are out-growths from others previously formed.</p>
+
+<p>In prolification and in multiplication the adventitious structures are
+of independent origin. In fission the new developments grow
+simultaneously with the older ones, of which, indeed, they are mere
+repetitions. Moreover, in fission the supplementary lobes do not, in
+general, project a plan different from that of the original structure,
+at least in the first instance, though their direction may ultimately
+become changed.</p>
+
+<p>In enation the new growth projects from a previously formed organ after
+it has attained to considerable size, or even after its ordinary
+proportions have been attained, and it sprouts out from the beginning in
+a plane which is at a considerable angle to that of the parent organ,
+and it is sometimes of a different structure from it, and has different
+functions to fulfil.</p>
+
+<p>Many of the instances that occur of scales projecting from petals, as in
+<i>Caryophylle&aelig;</i>, <i>Sapindace&aelig;</i>, &amp;c., the coronal filaments of
+passion-flowers, the cup of <i>Narcissus</i>, the appendages that beset the
+segments of the perianth in <i>Lilium lancifolium</i>, and other similar
+growths, may be referred to a like process. In many cases this has been
+proved by a study of the development of the flower, from which it
+appears that the growths in question are developed subsequently to the
+formation of the ordinary floral whorls. It is requisite, however, to be
+cautious in pronouncing upon the exact<span class='pagenum'><a name="Page_444" id="Page_444">[Pg 444]</a></span> nature of these bodies, in the
+absence of a knowledge of their period and mode of formation. They may
+be mere outgrowths from one or other of the customary whorls, or they
+may represent abortive stamens or petals, &amp;c. Where circumstances
+prevent the course of development from being traced, something may be
+inferred as to their real nature from their position in regard to the
+other parts of the flower, from their anatomical structure, and from
+analogy or comparison with like organs in other plants. The period of
+their formation is, perhaps, of less importance than was at one time
+supposed, since it is well ascertained that, in some cases, the
+formation of the parts of the flower, <i>e.g.</i> the stamens of mallows,
+follows a centrifugal rather than a centripetal order.</p>
+
+<p>In the case of monstrous developments of this nature too much care can
+hardly be exercised, and the observer should rarely venture on an
+explanation of the nature of the case from the evidence afforded by the
+monstrous growth apart from that to be derived from the study of the
+development and organization of the normal flower and from analogous
+formations in allied plants.</p>
+
+
+
+<p><b>Excrescences from axile organs&mdash;Warts.</b>&mdash;In a preceding paragraph the
+formation of gnaurs has been alluded to. There are other outgrowths,
+called warts, occasionally met with in trees, and which are more closely
+connected with the central tissues of the stem, while at the same time
+they are not provided with buds, in which two particulars warts differ
+from gnaurs.</p>
+
+<p>Excrescences of this kind often attain a very large size, and may be
+seen on old elms and other trees, but, as their formation is probably
+more pathological than teratological, no further notice of these
+structures need here be given. No special notice need here be taken of
+the tubercles on the roots of so many <i>Leguminos&aelig;</i>, nor of the peculiar
+excrescences on the roots of <i>Taxodium distichum</i>, as these appear to be
+normal formations. But it may be well to mention in this<span class='pagenum'><a name="Page_445" id="Page_445">[Pg 445]</a></span> place an
+anomalous development which occurs occasionally in <i>Ruscus aculeatus</i>,
+and in which, from the upper surface of the ordinary flattened leaf-like
+branch, projects at right angles a second similar branch, so that in
+section the appearance would be like that of the inverted letter t;
+thus, [symbol: Inverted upper-case T].</p>
+
+
+
+<p><b>Enation from foliar organs&mdash;Leaves.</b>&mdash;The development of adventitious
+lobes from leaves may take place either from their surfaces or their
+margins. A few illustrations may be given of each. In cabbage leaves a
+formation of adventitious lamin&aelig; projecting at right angles from the
+primary one may frequently be observed. In the instance figured (fig.
+210) the new growths proceeded almost exclusively from the thick midrib,
+which, in the figure, is shown cut through just above the base. Not only
+is the ordinary semilunar band of vascular tissue to be here seen, but a
+similar broken line of vessels exists on the upper side of the
+leaf-stalk; thus the whole structure resembles that of a stem or a
+branch as much as that of a true leaf.</p>

+
+<p>The development of secondary leaves from the surfaces of primary ones
+(phyllomania, autophyllogeny) has already been alluded to at <a href="#Page_355">p. 355.</a></p><p><span class='pagenum'><a name="Page_446" id="Page_446">[Pg 446]</a></span></p>
+
+<p>Some of the cases wherein a leaf seems to have a double lamina may be
+alluded to here, though possibly they would more properly be referred to
+fission. The appearance presented is as if four wings projected from the
+midrib, so that a cross section would be nearly in the form of [Symbol:
+)O( turned 90 degrees.]. In an orange leaf presenting this appearance
+the lower surface of one lamina was, as usual, dull in colour, while the
+upper surface of the subjacent lamina was likewise dull; hence the
+impression might arise that this was an instance of the adhesion of two
+leaves back to back, but the petioles were not twisted, as they must
+have been had two leaves thus been united, and neither in the petiole
+nor in the midrib was there the slightest indication of fusion, the
+vascular bundles being arranged in a circular manner, not in a
+horseshoe-like arrangement, as would have been the case had adhesion
+taken place.<a name="FNanchor_518_518" id="FNanchor_518_518"></a><a href="#Footnote_518_518" class="fnanchor">[518]</a> (<a href="#Page_33">See p. 33.</a>) </p><p><span class='pagenum'><a name="Page_447" id="Page_447">[Pg 447]</a></span></p>
+
+<p>Such leaves as those of the hedgehog holly, <i>Ilex Aquifolium</i>, var.
+<i>fero&aelig;</i>, and, to a less extent, bullate leaves, may also be mentioned
+here as illustrations of hypertrophy or enation.</p>
+
+<div class="center">

+</div>
+
+<p>When the increased development occurs at the margin of the leaves,
+especially, the result is a wavy or crisped appearance, "folia undulata,
+<i>vel</i> crispa."<a name="FNanchor_519_519" id="FNanchor_519_519"></a><a href="#Footnote_519_519" class="fnanchor">[519]</a> These<span class='pagenum'><a name="Page_448" id="Page_448">[Pg 448]</a></span> conditions occur normally in such leaves as
+those of <i>Rumex crispus</i>, <i>Malva crispa</i>, &amp;c., and are developed to an
+extreme degree in garden varieties of parsley, some kails, &amp;c., as well
+as in many ferns, but these are probably cases rather of fission than
+enation as here understood.<a name="FNanchor_520_520" id="FNanchor_520_520"></a><a href="#Footnote_520_520" class="fnanchor">[520]</a></p>
+
+
+
+<p><b>Enation from the sepals.</b>&mdash;The basal lobes of the calyx in <i>Campanula
+Medium</i>, under normal circumstances, may be referred to in illustration
+of this occurrence, while the adventitious spurs on the calyx of some
+monstrous flowers seem due also to a like cause. These have already been
+alluded to at p. 315.</p>
+
+
+
+<p><b>Enation from the corolla.</b>&mdash;The instances of this are more frequent than
+in the case of the calyx, and admit of classification according as they
+occur in polypetalous or gamopetalous flowers, on the outer or inner
+surface of the petals, &amp;c. Under natural circumstances the formation of
+scales, lobes, &amp;c., from the petals, as in some <i>Caryophylle&aelig;</i>,
+<i>Sapindace&aelig;</i>, &amp;c. &amp;c., may be explained, as already remarked, by this
+process, rather than by fission, chorisis, or by substitution of petals
+for stamens, &amp;c. Each case must, however, be examined on its own merits,
+as it is not safe to decide upon the arrangement of parts in one flower
+by simply referring to the analogy of others. In the following
+illustrations the course of development has not, in all cases, been
+observed, and hence the explanation here given must be taken with some
+reserve; for should it prove that the adventitious lobes, &amp;c., are
+formed simultaneously with the ordinary petals, the case will be one of
+chorisis rather than of enation, as here understood. Again, it may be
+that the supernumerary organs really represent petals or stamens in
+disguise, though this hypothesis demands the further assumption (in
+order to account for the interference with the law<span class='pagenum'><a name="Page_449" id="Page_449">[Pg 449]</a></span> of alternation) that
+suppression of certain organs has taken place.</p>
+
+<p>Taking first those instances in which the supplementary petals appear on
+the inner surface of the corolla, as being at once the most frequent,
+and as presenting the closest analogy, with similar conformations, under
+natural circumstances, certain double-flowered varieties of the Chinese
+primrose, <i>Primula sinensis</i>, may be mentioned. In these flowers the
+calyx is normal, the tube of the corolla is traversed by ten vascular
+bundles, and the limb is divided into ten fimbriated lobes. About
+halfway up the tube, on the inner surface, are given off five
+supernumerary petals, opposite to as many lobes of the corolla. Some of
+the supplementary petals have a stamen in front of them, in the same
+relative position as in the normal flower. In some cases the back or
+outer surface of the supplementary petal is turned towards the inner or
+upper surface of the primary corolla, thus [Symbol: ((turned 90 degrees
+cw]; while, in other instances, the front of the adventitious lobe is
+directed towards the corresponding surface of the original petal, thus
+[Symbol: () turned 90 degrees]. Whether these supernumerary petals are
+formed by chorisis or by enation cannot, with certainty, be determined
+without examining the early stages of development.</p>
+

+<p class="caption"> <span class="smcap">Fig.</span> 212.&mdash;<i>Datura fastuosa.</i> True corolla turned back to show the supernumerary corolla with the petal-like segments attached to its outer surface (reduced).</p>
+</div>
+
+
+<p>Of more interest are those instances where the adventitious growth is on
+the outside of the corolla; thus in a garden azalea there was
+intermediate between the calyx and the corolla, both of which were
+normal, a series of five petalodes, alternating with the sepals, and,
+therefore, opposite to the lobes of the corolla, and adherent with them
+at the very base, though elsewhere detached. These petalodes were
+concave on the surface looking towards the calyx, and were there
+brightly coloured, while the tint of the opposite surface looking
+towards the corolla was of a duller hue, corresponding with that of the
+outside of the corolla-tube. This arrangement of the colour was thus
+precisely similar to that which occurred in the four-winged leaves<span class='pagenum'><a name="Page_450" id="Page_450">[Pg 450]</a></span>
+already referred to at p. 446. In some flowers of <i>Datura fastuosa</i> a
+similar series of excrescences was observed; the calyx and the corolla
+were normal within the latter, intervening between it and the stamens
+was a second corolla produced by duplication, and adherent to the inner
+surface of this latter were five stamens. So far there was nothing very
+peculiar; it remains to say, however, that on the outer surface of the
+second corolla were five petal-like lobes closely adherent to it below,
+but partially detached above. The colour of the adventitious segments
+was paler on the outside than on the inner surface, as in the corolla
+itself. The position of the several parts was such that they were
+opposite one to the other; hence, while the lobes of the inner corolla
+were opposite to those of the outer one, the intermediate petalodes were
+opposite to both; thus:</p>

+<p class="caption"> <span class="smcap">Fig.</span> 213.&mdash;Gloxinia, with supernumerary segments on the outside of the true corolla.</p>
+</div>
+
+<p>A still more singular case is that of a variety of the Gloxinia,
+described originally by Professor Edouard Morren,<a name="FNanchor_521_521" id="FNanchor_521_521"></a><a href="#Footnote_521_521" class="fnanchor">[521]</a> but which is now
+becoming common in English gardens. When first observed these flowers
+were observed to produce petaloid segments outside the ordinary corolla,
+and partially adherent to (or rather, not completely separated from it)
+much as in the azalea before mentioned, the outer surface being brightly
+coloured, like the inner surface of the corolla in ordinary gloxinias.
+Being encouraged and tended by gardeners, in course of time, instead of
+a series of petalodes, more or less distinct from one another, a second
+corolla or "catacorolla" was formed outside the primary one, so that a
+hose in hose flower was produced, but, in this case, the supplementary
+flower was formed on the outside and not within the ordinary corolla.
+Moreover, the disposition of the colour was reversed, for in the
+outermost corolla the richest hues were on the outer surface, while in
+the inner or true corolla they were on the inside. </p><p><span class='pagenum'><a name="Page_452" id="Page_452">[Pg 452]</a></span></p>
+
+<p>Professor Morren considers the adventitious petalodes as rudiments of so
+many supplementary flowers, axillary to the calyx, and adnate to the
+corolla; each lobe then would, in this view, represent an imperfect
+flower, and the completed catacorolla would be formed of a series of
+confluent flowers of this description. But this view involves the
+assumption of the suppression of all the parts of the flower, except the
+lobes in question.</p>
+

+</div>
+
+<p>The view here propounded that the lobes in question are enations from
+the true petals, which become confluent, so as to form the catacorolla,
+is surely more simple, involves no assumptions of suppression of parts;
+and moreover, is borne out by the examination of some flowers, where the
+production of these adventitious<span class='pagenum'><a name="Page_453" id="Page_453">[Pg 453]</a></span> lobes from the outside of the minute
+partially developed petals could be distinctly seen.</p>
+
+
+
+<p><b>Enation from the stamens.</b>&mdash;An illustration of this process occurred in
+some double-flowered rhododendrons, which presented the following
+arrangement of parts:&mdash;calyx and corolla normal; within the latter eight
+petal-like stamens, forming a pseudo-corolla. The appearance presented
+by the petaloid filaments and anthers was as if they were adnate to the
+centre of the petals, but, on closer examination, it appeared that the
+petaloid expansion to which the dilated filament was apparently
+attached, was equally a part of the stamens; in other words, that the
+filament was provided with four petal-like wings, two on each side
+[Symbol: 00 topped by (turned cw 90&deg;, an o above and another ( turned cw
+above that]. This disposition was well seen in the anther, half of which
+was, in some cases, petaloid like the filament; in fact, the inner wing
+of the latter was directly continuous with the petal-like expansion from
+the anther. A section through the latter showed, going from within
+outwards, the cut edges of two perfect polliniferous lobes in the
+centre; and on either side the petaloid wing representing the remaining
+anther-lobe; outside these were the edges of the remaining wings, one on
+each side. (<a href="#Page_290">See p. 290</a>, fig. 155.)</p>
+
+
+
+<p><b>Enation from the carpels.</b>&mdash;The only instances of this that need be
+referred to are such cases as those in which spur-like projections,
+horns, tubercles, or winged expansions, are formed from the surface of
+the ovary during the course of its development. The extraordinary
+cornute oranges described and figured by Ferrari, Gallesio, and other
+writers on the genus <i>Citrus</i>, may be mentioned under this head. A
+similar formation occurs in the fruit of some species of <i>Solanum</i>. (See
+p. 316.)</p>

+case of fissiparous division of a leaf of <i>Prunus Laurocerasus</i>
+described by Prof. Alexander Dickson ('Seemann's Journ. Botany,' vol. v,
+1867, p. 323), and which did not come under the writer's notice till
+after the sheet relating to fission, p. 61, had been sent to press. Dr.
+Dickson thus speaks of this abnormal leaf:&mdash;"The petiole (unchanged)
+supported two lamin&aelig;, placed back to back, and united by their midribs
+(<i>i.e.</i> not separated) to within about an inch from their extremities,
+which were perfectly free from each other. These lamin&aelig; stood
+vertically, their edges being directed towards and away from the axis;
+and as they were placed back to back, the shining surfaces,
+corresponding in structure to the normal upper leaf-surface, were
+directed laterally outwards. In the axil of this abnormal leaf were two
+axillary buds. The existence of two leaf-apices and two axillary buds
+shows that this was not due to an accidental exuberance of development,
+but to fissiparous division, which, had it been complete, would have
+resulted in the replacement of a single leaf by two leaves. The
+arrangement in Prof. Dickson's leaf may be thus represented:
+[symbol:)OO(with X above]. The nature of the case may be even better
+seen by comparison with the normal arrangement, which would be [symbol:
+(OX turned 90 degrees ccw], while in those cases where the fission of
+the leaf occurs in the same plane as that of the primary lamina, as
+where a leaf splits into two lobes at the apex, with a midrib to each,
+the arrangement is as follows: [symbol: OX turned 90 degrees ccw, with 2
+arcs below], the X in all cases representing the position of the axis,
+the O that of the axillary bud, and the [symbol: (turned 90 degrees ccw]
+that of the lamin&aelig;."</p></div>

+
+
+ATROPHY.</h3>
+
+
+<p>Under the head of atrophy are included those cases wherein the organs
+affected are actually present, but in a dwarfed and stunted condition as
+compared with surrounding parts.</p>
+
+<p>The diminished size is, in such instances, obviously due to a partial
+development and to an arrest of growth at a certain stage, from the
+operation of various causes, either external or inherent to the
+organization itself. It may affect any part of the plant, and exists, in
+very varying degree, in different instances, being sometimes so slight
+in amount as not to preclude the exercise of the functions of the part;
+while in others, the structure is so incomplete that the office cannot
+be performed. These differences depend, of course, upon the stage of
+development which the organ had reached when its growth was checked. For
+practical purposes atrophy may be distinguished from suppression by the
+fact that in the latter case a certain element of the flower or plant
+which, under ordinary circumstances, is present, is entirely wanting,
+while, in the former class, it exists but in a rudimentary condition.</p>
+
+<p>Again, atrophy is to be separated from that general diminution in the
+size of the whole plant or of distinct parts of that plant which is
+comprised under the term "nanism." Thus the several dwarf varieties of
+plants (var. <i>nan&aelig;</i>), or those in which the leaves or flowers are
+smaller than usual (var. <i>parvifoli&aelig;</i>, v. <i>parviflor&aelig;</i>), are truly
+regarded as variations, and not as malformations properly so called.</p><p><span class='pagenum'><a name="Page_455" id="Page_455">[Pg 455]</a></span></p>
+
+<p>Atrophy is partial and special in its operation, nanism is general.</p>
+
+<p>Under ordinary circumstances atrophy is exemplified by the presence of
+rudimentary or imperfect organs, as, for instance, in <i>Pentstemon</i>,
+<i>Scrophularia</i>, &amp;c., where one stamen is atrophied.</p>
+
+<p>For convenience sake atrophy may be divided into abortion and
+degeneration, the first including cases where, from arrest of
+development occurring at an early stage, organs are present; but in a
+much smaller and more rudimentary condition than usual, their form and
+general appearance, except so far as regards their dimensions, not being
+materially altered. On the other hand, in cases of degeneration,
+development is not entirely checked, but rather perverted, so that not
+only the dimensions are lessened, but the form is altered.</p>
+
+
+
+
+<h4><a name="CHAPTER_Ik" id="CHAPTER_Ik"></a>CHAPTER I.<br />
+
+ABORTION.</h4>
+
+
+<p>The sense in which this term is here understood has been explained in
+the preceding paragraph. It is only necessary to say further, that cases
+of abortion are to be distinguished from those of suppression, on the
+one hand, and those of degeneration on the other. In suppression there
+is from the first an absolute deficiency of a particular organ. In
+degeneration the part is present, but in a diminished and perverted
+condition. In abortion it exists, but in a stunted and dwarfed, but not
+otherwise permuted state.</p>
+
+
+
+<p><b>Abortion of axile organs.</b>&mdash;When the main stem is arrested in its growth,
+the habit and general appearance of the plant are materially altered, as
+in the so-called stemless plants, <i>plant&aelig; acaules</i>. In these the
+internodes<span class='pagenum'><a name="Page_456" id="Page_456">[Pg 456]</a></span> are so slightly developed that the leaves are closely
+crowded in tufts or rosettes. When this shortening of the stem
+(acaulosia) occurs, without other considerable change in other organs,
+the deviation is classed under the head of variation rather than of
+monstrosity; and, indeed, in very many plants, this arrested growth of
+the axis is the rule rather than the exception. When occurring in an
+abnormal manner, atrophy of the stem is most frequently attended by
+other more or less grave alterations in other structures; thus
+Moquin-Tandon<a name="FNanchor_522_522" id="FNanchor_522_522"></a><a href="#Footnote_522_522" class="fnanchor">[522]</a> cites an instance of <i>Camphorosma monspeliaca</i>,
+wherein the stems presented the form of very short, hard, woody
+tubercles, thickly clothed with deformed leaves, and invested by a vast
+number of hairs, longer and more dense than usual. A similar deformity
+sometimes occurs in an Indian species of <i>Artabotrys</i>; in these
+specimens the branchlets are contracted in length, and bear numerous
+closely packed scaly leaves, densely hairy, and much smaller than
+ordinary.</p>
+
+<p>Spines and thorns may he looked on as atrophied branches, and seem to
+result from poorness of soil, as the same plants, which, in hungry land,
+produce spines, develop their branches to the full extent when grown
+under more favorable conditions.<a name="FNanchor_523_523" id="FNanchor_523_523"></a><a href="#Footnote_523_523" class="fnanchor">[523]</a></p>
+
+<p>In the birch an arrest of development in some of the branches is of
+common occurrence. The branch suddenly ceases to grow in length; at the
+same time it thickens at the end into a large bulbous knob, from which
+are developed a profusion of small twigs, whose direction is sometimes
+exactly the reverse of that of the main branch. (<a href="#Page_347">See p. 347.</a>)</p>
+
+<p>The branches of the common spruce fir, especially the lateral ones, when
+attacked by a particular species of aphis, are very apt to be developed
+into a cone-like excrescence.<a name="FNanchor_524_524" id="FNanchor_524_524"></a><a href="#Footnote_524_524" class="fnanchor">[524]</a> </p><p><span class='pagenum'><a name="Page_457" id="Page_457">[Pg 457]</a></span></p>
+
+<p>A shortened condition of the flower-stalks occurs occasionally, greatly
+altering the general character of the inflorescence. This has been
+observed in pelargoniums and in the Chinese primrose, in both of which
+the effect was to replace the umbellate form of inflorescence by a
+capitate one.</p>
+
+
+
+<p><b>Abortion of the receptacle.</b>&mdash;Here may be mentioned those cases of
+flowers with habitually inferior ovary (real or apparent), in which the
+receptacle fails, from some cause or other, to dilate as usual. This has
+already been alluded to under the head of Prolification, Displacements,
+&amp;c. (pp. 78, 130, &amp;c., figs. 35&ndash;37, 64, &amp;c.), and hence requires only
+incidental comment in this place. There are, however, certain other
+cases of a similar nature which may here be referred to; such as the
+abortive condition of the inferior ovary, or rather of the receptacle,
+that usually encircles the ovary in <i>Composit&aelig;</i> and <i>Umbellifer&aelig;</i>. In
+the former natural order the following plants have been met with in this
+condition:&mdash;<i>*Tragopogon pratense!</i>, *<i>Cirsium arvense</i>, <i>Hypoch&aelig;ris
+radicata</i>, <i>Senecio vulgaris!</i>, <i>Coreopsis Drummondi</i>. In the latter
+order, <i>Daucus Carota!</i> <i>&OElig;nanthe crocata!</i> and <i>Thysselinum
+palustre</i>, seem most frequently to have been observed in this
+state.<a name="FNanchor_525_525" id="FNanchor_525_525"></a><a href="#Footnote_525_525" class="fnanchor">[525]</a> In some gourds the receptacle may be seen<span class='pagenum'><a name="Page_458" id="Page_458">[Pg 458]</a></span> partially
+developed only, and forming a kind of cup, from which the true carpels
+protrude.</p>
+
+
+
+<p><b>Abortion of the leaves.</b>&mdash;Arrest of growth in the leaves occurs in
+different ways; sometimes the whole leaf is smaller than usual; at other
+times certain parts only are reduced in size; while, in a third class of
+cases, portions of the leaf are entirely suppressed.</p>
+
+<p>Moquin<a name="FNanchor_526_526" id="FNanchor_526_526"></a><a href="#Footnote_526_526" class="fnanchor">[526]</a> mentions having seen the leaves of <i>Chenopodium vulvaria</i>,
+and of <i>Diplotaxis muralis</i> reduced to a fourth of their natural size;
+and he alludes to other cases of the same nature, seen by other
+observers, in <i>Hypericum perforatum</i> and <i>Blitum polymorphum</i>.</p>
+
+<p><i>Nicandra physaloides</i><a name="FNanchor_527_527" id="FNanchor_527_527"></a><a href="#Footnote_527_527" class="fnanchor">[527]</a> has also been met with in a similar
+condition, which, indeed, is a common result of insect-puncture, and of
+fungous growth in plants. Those instances in which the leaf is
+diminished in size, without any attendant malformation in other organs,
+may be regarded rather as variations than as monstrosities, as in the
+case of the entire-leaved varieties of those plants which ordinarily
+have cut or divided leaves, <i>e.g.</i> <i>Plantago Coronopus</i>, var.
+<i>integrifolia</i>, <i>Papaver Rh&oelig;as integrifolia</i>, &amp;c. &amp;c. The same remark
+may be made of those specimens in which one part of the leaf is
+developed to a less extent than another, as happens in the submerged
+leaves of such plants as <i>Ranunculus aquatilis</i>, <i>Cabomba aquatica</i>, the
+spiney leaves of <i>Berberis</i>, the fenestrated leaves of <i>Ouvirandra</i>, &amp;c.
+In the illustrations last cited the relative deficiency of one portion,
+as contrasted with another, takes place as a constant occurrence, and is
+uniform and regular throughout the whole leaf. When, on the other hand,
+the deficiency in question happens accidentally and irregularly, the
+change may be considered as a malformation. One side of the blade of the
+leaf is frequently affected in this manner, the other portions remaining
+unaffected. It would appear as if any plant might be<span class='pagenum'><a name="Page_459" id="Page_459">[Pg 459]</a></span> thus altered, but
+the following species appear to be particularly subject to this change:
+<i>&AElig;esculus Hippocastanum</i>, <i>Digitalis purpurea</i>, <i>Morus alba</i>, <i>Fagus
+silvatica contracta</i> (hort.), <i>Codi&aelig;um variegatum</i> var. <i>erosum</i>
+(hort.), <i>Broussonettia papyrifera</i>, <i>Scolopendrium vulgare</i>, &amp;c.</p>
+
+<p>Frequently this irregular diminution in proportion is coexistent with an
+unusual degree of cleavage or laciniation of the margin, as in <i>Acer
+platanoides laciniatum</i>, <i>Tilia asplenifolia</i>, <i>Alnus imperialis</i>
+(hort.), <i>Fagus silvatica</i> var. (hort.), &amp;c.</p>
+
+<p>In the case of what are sometimes termed interrupted leaves, the laminar
+portions of the leaf are here and there deficient on both sides of the
+midrib, leaving small portions of the latter, as it were, denuded and
+connecting the segments of the lamin&aelig; one with the other. This has been
+observed amongst other plants in <i>Veronica latifolia</i>, <i>Broussonettia
+papyrifer</i>, <i>Codi&aelig;um variegatum</i> var. <i>interruptum</i> (hort.),
+<i>Scolopendrium vulgare</i>, &amp;c.<a name="FNanchor_528_528" id="FNanchor_528_528"></a><a href="#Footnote_528_528" class="fnanchor">[528]</a> (<a href="#Page_328">See p. 328.</a>)</p>
+
+<p>In some of the leaves which have been already referred to in
+illustration of the inordinate growth of the cellular portions, the
+increased development of parenchyma is associated with a contracted
+state of the midrib and its branches, producing a puckered appearance of
+the leaf, an exaggerated degree of that change which produces what are
+termed "folia bullata." In illustration may be cited various species of
+<i>Mentha</i>, <i>Perilla</i>, <i>Coleus</i>, <i>Fagus silvatica crispa</i>, <i>Cytisus</i>,
+<i>Laburnum</i> var., and other forms, cultivated in gardens for their
+singularity.</p>
+
+<p>Entire absence of the stalk of the leaf occurs normally in sessile
+leaves; on the other hand the blade of the leaf is only occasionally
+developed in the phyllodineous Acacias, in some species of <i>Oxalis</i>,
+<i>Indigofera</i>, <i>Lebeckia</i>, <i>Ranunculus</i>, <i>Bupleurum</i>, &amp;c.</p><p><span class='pagenum'><a name="Page_460" id="Page_460">[Pg 460]</a></span></p>
+
+<p>De Candolle,<a name="FNanchor_529_529" id="FNanchor_529_529"></a><a href="#Footnote_529_529" class="fnanchor">[529]</a> from a consideration of <i>Strelitzia juncea</i>, in which
+the petiole alone is developed, was led to the inference that in many
+monocotyledonous plants the blade of the leaf was never developed, the
+portion present being the sheath or stalk, unprovided with limb. The
+correctness of this inference is shown, amongst other things, by the
+occasional presence of a leaf-blade in <i>Strelitzia juncea</i> itself.</p>
+
+<p>Occasionally the laminar portions of the leaf are completely wanting,
+leaving only the main ribs, as in the case of <i>Berberis</i>, while the
+adjoining figure (fig. 215) represents an instance of a cabbage wherein
+the innermost leaves are represented by thick fleshy cylindrical bodies
+corresponding to the midribs of the ordinary leaves. There is in
+cultivation a variety of the cabbage which constantly presents this
+peculiarity.</p>

+
+<p>The suppression of one or more leaflets of a compound leaf has already
+been referred to at p. 396.</p>
+
+
+
+<p><b>Abortion of the perianth, calyx, and corolla.</b>&mdash;Illustrations of partial
+development in these organs are not rare, under ordinary circumstances,
+as for instance the "obsolete" calyx of Umbellifers. In the cauliflower
+the branches of the inflorescence are contracted in length, while their
+succulence is much increased; at their<span class='pagenum'><a name="Page_461" id="Page_461">[Pg 461]</a></span> extremities they bear crowds of
+imperfect flowers, in which the calyx only is visible, and that only in
+a rudimentary and partially developed condition. Imperfect development
+of the whole or of some of the constituent parts is more common in the
+case of the corolla than in that of the calyx. In <i>Arenaria
+serpyllifolia</i> the petals, especially in autumn, are only one fourth the
+length of the sepals. <i>Anagallis ph&oelig;nicea</i>, <i>Honckenya peploides</i>,
+<i>Arabis alpina</i>, <i>Ranunculus auricomus</i>, <i>Rubus fruticosus</i>, and
+<i>Geranium columbinum</i>, also frequently afford illustrations of this
+circumstance.</p>
+
+<div class="center">

+<p class="caption"> <span class="smcap">Fig.</span> 216.&mdash;Abortion of four out of five petals, <i>Viola tricolor</i>, side and front views.</p>
+</div>
+
+<p>At fig. 216 is represented a pansy in which four of the five petals were
+very small and colourless, while the lower spurred petal was of the
+usual size and colour. In this flower the stamens and pistils were
+wholly suppressed, and the flower-stalk, instead of being bent near the
+flower, retained its primary straight direction. Similar atrophic
+conditions of the corolla occur habitually among <i>Violace&aelig;</i>.</p>
+
+<p>The diminished size of the petals sometimes coexists with an increase in
+their number, as in a flower of <i>Streptocarpus Rexii</i>, mentioned by
+Bureau.<a name="FNanchor_530_530" id="FNanchor_530_530"></a><a href="#Footnote_530_530" class="fnanchor">[530]</a></p>
+
+<p>Among monocotyledons this partial development seems to be even more
+frequent than in dicotyledons. In addition to the well-known cases of
+certain species of <i>Bellevalia</i> and <i>Muscari</i>, wherein the uppermost
+flowers of the raceme are more or less atrophied (see<span class='pagenum'><a name="Page_462" id="Page_462">[Pg 462]</a></span> p. 347, fig.
+179), a few less common illustrations may be cited. In crocuses it is
+not a very uncommon circumstance to find the three inner segments of the
+perianth smaller than natural, and generally unequal in size. This
+occurs without any other perceptible change in the flower.</p>
+
+<p>Schlechtendal<a name="FNanchor_531_531" id="FNanchor_531_531"></a><a href="#Footnote_531_531" class="fnanchor">[531]</a> mentions a flower of <i>Fritillaria imperialis</i> in
+which the perianthial leaves were relatively very small, and destitute
+of the usual nectary, while the stamens, on the other hand, were of
+their natural size and appearance. Fresenius<a name="FNanchor_532_532" id="FNanchor_532_532"></a><a href="#Footnote_532_532" class="fnanchor">[532]</a> records a similar
+occurrence in the same plant.</p>
+
+<p>Morren<a name="FNanchor_533_533" id="FNanchor_533_533"></a><a href="#Footnote_533_533" class="fnanchor">[533]</a> gives details of like appearances in <i>Hymenocallis
+americana</i>, and Delavaud<a name="FNanchor_534_534" id="FNanchor_534_534"></a><a href="#Footnote_534_534" class="fnanchor">[534]</a> in <i>Tigridia pavonia</i>.</p>
+
+<p>In certain orchids an arrested development of the perianth is habitual,
+as in <i>Oncidium abortivum</i> (fig. 217), where, on a large branching
+panicle, numerous abortive, but few perfect, flowers are produced. In a
+similar way the petals and labellum of <i>Odontoglossum
+Uro-Skinneri</i> have been found reduced to filamentous processes.

+
+
+<p><b>Abortion of the stamens.</b>&mdash;Atrophy of one or more stamens is of very
+common occurrence, as a general rule, in many genera of plants, <i>e.g.</i>
+<i>Scrophularia</i>, <i>Erodium</i>, many <i>Restiace&aelig;</i>, &amp;c. &amp;c. As a strictly
+teratological condition atrophy of the stamens is more rare than
+complete suppression. It has been noticed in <i>Arabis alpina</i>, <i>Cerastium
+glomeratum</i>, <i>C. tetrandrum</i>, <i>Rhamnus catharticus</i>, <i>Anemone</i>,
+<i>Hepatica</i>, &amp;c. It happens frequently among Orchids both wild and
+cultivated. In the <i>Hymenocallis</i> flowers described by the elder Morren,
+four out of five stamens were atrophied. In other flowers, otherwise
+perfectly formed, one abortive stamen was found bearing a spherical
+indehiscent anther. All these atrophied anthers of <i>Hymenocallis</i> were
+found to contain pollen, differing at first sight but little from what
+is usual, but presenting this important peculiarity, that while the
+normal pollen does not burst until it comes into contact with the
+stigma, in the abnormal flowers the outer coat of the pollen-grains
+split while still within the anther, from which latter, indeed, they
+could not escape, owing to the indehiscent nature of the latter. Again,
+the pollen-tube of the abnormal grains cracked, in its turn, on mere
+exposure to the air, and liberated the fovilla, so that the pollen of
+these atrophied anthers was necessarily impotent, because it opened
+before it could be applied to the stigma, even had that been rendered
+possible by the opening of the anther.</p>
+
+<p>An abortive condition of the stamens and of the pollen, is of very
+common occurrence among hybridised plants. Gaertner and other writers
+have spoken of this defective condition as contabescence.<a name="FNanchor_535_535" id="FNanchor_535_535"></a><a href="#Footnote_535_535" class="fnanchor">[535]</a> It forms
+one reason for the sterility so frequently observed in the case of true
+hybrids. In some hybrid passion-flowers, while all other parts of the
+flower were apparently perfect, even to the ovules, the stamens were<span class='pagenum'><a name="Page_464" id="Page_464">[Pg 464]</a></span>
+atrophied, and distorted, and contained little or no pollen; the few
+grains of the latter being smaller than usual. (See under Heterogamy,
+pp. 193&ndash;196, and p. 398.)</p>
+
+
+
+<p><b>Abortion of the pistil, fruit, &amp;c.</b>&mdash;Traces of the carpels occur in many
+male flowers of unisexual plants, <i>e.g.</i> <i>Sterculiace&aelig;</i>,
+<i>Euphorbiace&aelig;</i>, <i>Restiace&aelig;</i>, &amp;c. &amp;c., and in some natural orders there
+appears to be a tendency towards a di&oelig;cious condition, <i>e.g.</i>
+<i>Caryophylle&aelig;</i>, as in <i>Lychnis dioica</i>, <i>Silene otites</i>, <i>Arenaria
+tetraquetra</i>, &amp;c. The last-named plant is stated to have, in some cases,
+imperfect pistils; in others, rudimentary stamens; while a third set of
+flowers are hermaphrodite.<a name="FNanchor_536_536" id="FNanchor_536_536"></a><a href="#Footnote_536_536" class="fnanchor">[536]</a> The ovary of aconites, according to
+Moquin, is very subject to atrophy.</p>

+considered by Steudel to form a distinct species. It is, however, merely
+a variety in which the fruits have not become succulent.<a name="FNanchor_539_539" id="FNanchor_539_539"></a><a href="#Footnote_539_539" class="fnanchor">[539]</a></p>
+
+<p>Schlechtendal describes<a name="FNanchor_540_540" id="FNanchor_540_540"></a><a href="#Footnote_540_540" class="fnanchor">[540]</a> the ordinarily baccate fruit<span class='pagenum'><a name="Page_466" id="Page_466">[Pg 466]</a></span> of a vine as
+becoming dry, and even dehiscing by valves like a capsule.</p>
+
+<p>In maize it occasionally happens that one or two of the longitudinal
+series of fruits become abortive, leaving a smooth furrow, at first of a
+greenish colour, but ultimately of a reddish yellow. Often a second row
+of fruits, opposite to the first, is also atrophied, so that the whole
+spike changes its cylindrical form for a flattened one.<a name="FNanchor_541_541" id="FNanchor_541_541"></a><a href="#Footnote_541_541" class="fnanchor">[541]</a> See also
+under Heterogamy, Meiophylly, &amp;c.</p>
+
+
+
+<p><b>Abortion of the ovules.</b>&mdash;In the case of a pluri-ovulate ovary it rarely
+happens that all the ovules attain to maturity, some never get
+fertilised, others, pressed on by their neighbours on either side,
+become impeded in their development, and finally disappear, or remain as
+rudiments.<a name="FNanchor_542_542" id="FNanchor_542_542"></a><a href="#Footnote_542_542" class="fnanchor">[542]</a> This is the case, under ordinary circumstances, and
+still more so in the case of hybrid plants, or of monsters. Where the
+outer coats of the ovule become more or less leafy in appearance (<a href="#Page_262">see p.
+262</a>), the inner investments become more or less atrophied, or are even
+more frequently entirely suppressed, as is also the nucleus.</p>
+
+<p>In other cases, a simple arrest of development takes place; the ovule,
+for instance, which should be anatropal, remains straight, while the
+integuments, checked in their development, form imperfect sheaths from
+which the shrivelled nucleus protrudes.</p>
+
+
+
+<p><b>Depauperated Ferns.</b>&mdash;The preceding illustrations have been taken from
+flowering plants chiefly, but a similar defective development is
+manifested in cryptogamous plants. The contraction and imperfect
+development of the fronds of some varieties of ferns, hence called
+depauperated, may receive passing notice, as also the cases in which the
+sori or clusters of spore cases are denuded of their usual covering,
+owing to the abortion<span class='pagenum'><a name="Page_467" id="Page_467">[Pg 467]</a></span> or imperfect development of the indusium, as in
+what are termed exindusiate varieties.<a name="FNanchor_543_543" id="FNanchor_543_543"></a><a href="#Footnote_543_543" class="fnanchor">[543]</a></p>
+
+
+
+<p><b>General remarks on abortion, coincident changes, &amp;c.</b>&mdash;Reference has
+already been made, while treating of hypertrophy, suppression, &amp;c., to
+certain other changes affecting the flower at the same time. Atrophy of
+one organ or set of organs, for instance, is frequently accompanied by a
+compensating hypertrophy or by an increased number of other parts. In
+the feather-hyacinth, <i>Muscari comosum</i>, var., <i>monstrosum</i>, the absence
+of flowers is compensated for by the inordinate formation of brightly
+coloured threads which appear to be modified pedicels (<a href="#Page_347">see pp. 347</a>,
+348); so also in the wig plant, <i>Rhus Cotinus</i>. So the atrophy of the
+stamens, in some flowers, is coincident with the hypertrophy of the
+pistil. Thus, Unger, 'Denkschr. d. Kais. Acad. der Wissensch. Math. Nat.
+Classe,' Mai 25, 1848, p. 103, tab. ix, describes a case wherein the
+corolla and stamens of <i>Desmodium marylandicum</i> were atrophied, while
+the calyx and legume, on the other hand, were hypertrophied.</p>
+
+<p>Fusion of the members of one whorl with one another, or with the
+components of an adjacent series, often entails atrophy or suppression,
+either in the united organs themselves, or in adjacent ones. A
+foliaceous condition of the outer portions of a flower is very generally
+attended by atrophy or complete suppression of the inner portions.</p>
+
+<p>From this point of view the observations of Morren<a name="FNanchor_544_544" id="FNanchor_544_544"></a><a href="#Footnote_544_544" class="fnanchor">[544]</a> on the different
+degrees of atrophy up to complete suppression, observable in the flowers
+of <i>Bellevalia comosa</i>, are of importance. According to this observer,
+the most highly differentiated parts, such as the stigmas, the ovules,
+and the anthers, are the first to disappear,<span class='pagenum'><a name="Page_468" id="Page_468">[Pg 468]</a></span> the filaments often being
+developed without anthers. Ultimately a deformed and empty perianth
+alone remains. In the ordinary course of things the mouth of the
+perianth is open, but in some of these malformations it is closed, and
+when that happens, the effects of atrophy are the more observable in the
+stamens and pistils.</p>
+
+<p>The impotence of the pollen in certain atrophied flowers, as noticed by
+the same observer, is of much interest, especially in reference to the
+sexual relationship between the different forms in polymorphic flowers
+as studied by Mr. Darwin.</p>
+
+<p>A change in direction may also be noted as a common accompaniment of
+atrophy or suppression; thus, in a capsule of <i>Veronica Beccabunga</i>,
+which was one-celled by the abortion of one carpel, the style was
+lateral instead of terminal.</p>
+
+<p>As to the causes of these structural deviations but little is known;
+certain of them have been already alluded to. In some cases atrophy and
+suppression maybe regarded as permanent states of a condition usually
+transitory, but this is clearly not always the case. Among external
+causes anything bringing about an enfeebled condition might be supposed
+to lead to atrophy, or suppression of some parts.</p>
+
+<p>Gaertner<a name="FNanchor_545_545" id="FNanchor_545_545"></a><a href="#Footnote_545_545" class="fnanchor">[545]</a> attributes the arrested development and fall of flowers to
+some among the following causes:&mdash;1. non-application of the pollen of
+the same variety, and consequent imperfect fertilisation; 2. any
+considerable injury to the calyx, &amp;c.; 3. destruction of the style or
+stigma before the fertilisation of the ovary; 4. application to the
+stigma of imperfect or heterogeneous pollen or indifferent pulverulent
+matter; 5. defective conceptive power in the ovary.</p>
+
+<p>Abortion of the ovules is considered by the same authority to be due
+to&mdash;1. deficiency of heat; 2. excess of moisture; 3. peculiar formation
+of the ovary; 4. over-luxuriant development of roots or buds; 5.
+peculiar<span class='pagenum'><a name="Page_469" id="Page_469">[Pg 469]</a></span> conditions of cultivation; thus, cuttings and layers produce
+sterile and abortive seeds much more frequently than plants of the same
+species raised from seed; 6. abortion of the seed is often combined with
+luxuriant development of the walls of the fruit.</p>
+
+<p>Temperature and climatal changes in general seem not to be without
+effect, as has been already mentioned in the case of <i>Arenaria
+tetraquetra</i>, which is polygamous when growing in mountain districts.
+Other illustrations of a similar character are mentioned under the head
+of Heterogamy (p. 196).</p>
+
+<p>Pressure has been already alluded to as one of the most obvious of the
+inducing causes of atrophy and suppression.</p>
+
+<p>In the case of <i>Ranunculus auricomus</i> before cited, in which the petals
+are rarely perfect, M. de Rochebrune considers that the deficiencies in
+question depend, in great measure, on the amount of moisture in the
+localities where the plant grows. In most places the flowers and carpels
+are apt to become more or less abortive, while the leaves are luxuriant;
+while, in dry places, the foliage is small, but the flowers are more
+perfect. This is quite consonant with other facts relating to the
+development of flowers or of leaves in general.</p>
+
+<p>But while external agencies undoubtedly play some part in bringing about
+these changes, it is almost certain that internal causes inherent to the
+organization of the plant are more important. Mr. Darwin<a name="FNanchor_546_546" id="FNanchor_546_546"></a><a href="#Footnote_546_546" class="fnanchor">[546]</a> accounts
+for the existence of rudimentary organs by the operation of the general
+rule of inheritance, and explains their stunted condition as the effect
+of disuse, not so much, of course, in the particular flower as in its
+predecessors. This disuse may be the result of the superior efficacy of
+foreign pollen as contrasted with that formed in the individual flower
+itself. In this way many hermaphrodite flowers tend to become
+di&oelig;cious, as in <i>Caryophyllace&aelig;</i>, <i>Orchidace&aelig;</i>, <i>Plantaginace&aelig;</i>,
+<i>Primulace&aelig;</i> and other orders. </p><p><span class='pagenum'><a name="Page_470" id="Page_470">[Pg 470]</a></span></p>
+
+<p>Although many of the circumstances above mentioned apply to plants whose
+structure is habitually rudimentary, there is no reason why they may
+not, under due restrictions, be applied to plants whose organs are only
+occasionally defective.</p>

+465, gives the following account of the formation of this peculiar
+growth:&mdash;"In the autumn the parent aphis deposits her eggs at the base
+of the embryo leaves, within the bud destined to produce the shoots of
+the following year. When these begin to burst and expand in spring, the
+leaves, at whose bases the eggs have been deposited, instead of
+increasing in length, enlarge at the base, and form a cell or cyst whose
+mouth is at first closed by a red velvety-looking substance. If opened
+in this state a nest of small greenish aphides is distinctly visible,
+and at a certain period, or when they have acquired maturity, which is
+towards the end of the summer, the mouth of the cell opens and the
+insects fly off to inflict a similar injury upon the nascent buds of the
+year. In some instances the leaves of only a portion of the
+circumference of a shoot are affected, in which case, though a slight
+distortion may take place, the branch is not prevented from elongating;
+but in others, where the whole of the leaves around the shoot are
+converted into nidi, elongation is prevented and distortion to a great
+extent takes place."</p></div>

+Thomson, 'Trans. Bot. Soc. Edinb.,' 1851, July 10th; Berkeley,
+'Gardeners' Chronicle,' June 22nd, 1867, p. 654. A similar case is
+described by Dr. Robb, in Sir W. Hooker's 'Journal of Botany,' 1841,
+vol. iii, p. 99, with illustrative figures. The specimens there
+described were produced at New Brunswick, where plum trees flower very
+freely, but seldom produce ripe fruit. Dr. Robb's account is as
+follows:&mdash;"In the summer of 1839 I had an opportunity of watching the
+process of destruction among the plums, and it was as follows&mdash;Before or
+soon after the segments of the corolla had fallen off, the ovarium had
+become greenish yellow, soft, and flabby. As the fruit continued to
+increase in magnitude, its colour grew darker and of a more ruddy
+yellow, and at the end of a fortnight or three weeks the size of the
+abortive fruit rather exceeded that of a ripe walnut. In fact, an
+observer might imagine himself to be walking amongst trees laden with
+ripe apricots, but, like the fabled fruit on the banks of the Dead Sea,
+these plums, though tempting to the eye, when examined, were found to be
+hollow, containing air, and consisting only of a distended skin,
+insipid, and tasteless. By-and-bye a greenish mould is developed on the
+surface of the blighted fruit; then the surface becomes black and
+shrivelled, and at the expiration of a month from the time of flowering
+the whole are rotten and decomposed. The flower appears about the
+beginning of June, and before August there is hardly a plum to be seen.
+It is curious that where two flower-stalks arise from one point of the
+branch, one will often go on to ripen in the normal way, while the other
+will become abortive, as above described."
+</p><p>
+In a specimen described by Mr. Berkeley there were two distinct ovules
+of equal size close to the apex of the fruit, connected with the base by
+vessels running down the walls. It should be observed that there is a
+worthless variety of plum, Kirke's stoneless, or Sans Noyau, in which
+the kernel is not surrounded by any bony deposit.</p></div>

+
+DEGENERATION.</h4>
+
+
+<p>While the terms atrophy and abortion apply in the main to a mere
+diminution of size, as contrasted with the ordinary standard,
+degeneration may be understood to apply to those cases in which not only
+is the absolute bulk diminished, but the whole form is altered and
+depauperated. Degeneration, thus, is the result not so much of a
+deficiency in growth as of a perversion of development.</p>
+
+<p>Under natural, <i>i.e.</i> habitual circumstances, the formation of pappus
+in place of a leafy calyx may be considered as an illustration of
+degeneration. It is evident, however, that no very decided line of
+demarcation can be drawn between cases of perversion and of arrest of
+development.</p>
+
+
+
+<p><b>Formation of scales.</b>&mdash;These may be mere epidermal excrescences, or they
+may be the abortive rudiments of leaves. Of this latter nature are the
+"cataphyllary" leaves which invest the root stocks of so many perennial
+plants, the perul&aelig; of leaf-buds, or the pale&aelig; on the common receptacle
+of composite flowers. Other illustrations of a like character are to be
+met with in the<span class='pagenum'><a name="Page_471" id="Page_471">[Pg 471]</a></span> membranous scales that represent leaves in <i>Ruscus</i>,
+<i>Asparagus</i>, <i>Pinus</i>, &amp;c. Similar productions are met with within the
+flower, where they may occur as the representatives of sepals, petals,
+stamens, or pistils, or as mere excrescences. (See Enation.) Whole
+families of plants, <i>e.g.</i> <i>Sapindace&aelig;</i>, are characterised by the
+presence of these organs, which are often of great interest to the
+morphologist as indicating the true symmetry of the flower, while they
+have acquired fresh importance since the publication of Mr. Darwin's
+work on the 'Origin of Species,' wherein we are taught to regard these
+rudiments as, in many cases, vestiges of organs that were more
+completely developed in the progenitors of the present race of plants,
+and the exercise of whose functions, from some cause or other, having
+been rendered impossible, the structures become, in process of time,
+proportionately stunted.</p>
+
+<p>Thus, in di&oelig;cious plants we frequently find traces of stamens in the
+female flowers, and rudiments of the pistil in the male flower,
+indicating, according to the Darwinian hypothesis, that the ancestors of
+these plants were hermaphrodite (see Heterogamy).</p>
+
+<p>Mr. Darwin has also shown that, in some cases, the utmost degree of
+fertility is attained, not from the action of the pollen on the stigma
+of the same flower, but on the influence of the male element of one
+blossom upon the female organs of another flower on another individual
+plant.</p>
+
+<p>Hence, in such plants there is a tendency to a separation of the sexes,
+while, from what has been before stated, it might be expected that
+rudiments of the male or female organs would be found, and also as a
+result of the operation of the law of inheritance. On the same
+principles it is easy to understand the occasional presence of the
+perfect in place of the rudimentary organs, as in <i>Dianthus</i>.</p>
+
+<p>In some instances the assumption of a scale-like form by any organ is
+attended by a change in texture, the organs becoming dry and scarious,
+or fleshy.<span class='pagenum'><a name="Page_472" id="Page_472">[Pg 472]</a></span> Moquin cites in illustration of the first phenomenon the
+flower of a <i>Vicia</i>, in which the petals were thick and fleshy, like the
+scales of a bulb; and of the second the leaves of a <i>Chrysanthemum</i>,
+which were replaced by small, glossy scales, like those which invest
+ordinary leaf-buds. Sometimes the entire flower is replaced by
+accumulations of small, acute, green scales. Cases of this kind, wherein
+the flowers of a pea and of the foxglove were replaced by collections of
+small ovate green scales packed one over the other till they resembled
+the strobile of a hop, have been already alluded to. Most of these
+scales are represented as having had other accumulations of scales in
+their axils.</p>
+
+<p>Similar collections of scales may frequently be met with in the birch
+and in the oak, and probably represent abortive leaf-buds. Other cases
+of a like kind in <i>Gentiana Amarella</i>, where the scales are coloured,
+are mentioned elsewhere.</p>
+
+<p>In some kinds of <i>Campanula</i> a similar change is not uncommon.</p>
+
+
+
+<p><b>Formation of hairs, spines, &amp;c.</b>&mdash;The adventitious production of hairs is
+likewise frequently due to an arrested growth, in some cases arising
+from pressure impeding the proper development of the organ. In other
+cases the formation of hair seems to accompany the diminished
+development of some organ, as on the barren pedicels of the wig plant,
+<i>Rhus Cotinus</i>. A similar production of hair may be noticed in many
+cases where the development of a branch or of a flower is arrested, and
+this occurs with especial frequency where the arrest in growth is due to
+the puncture of an insect, or to the formation of a gall. In such cases
+the hairs are mere excrescences from the epidermis.</p>
+
+<p>Prickles differ but little from hairs save in their more woody texture,
+but true spines or thorns are modifications either of a leaf or of a
+branch. Their presence seems often dependent on the soil in which the
+plants grow, or on other external circumstances.</p><p><span class='pagenum'><a name="Page_473" id="Page_473">[Pg 473]</a></span></p>

+
+<p><b>Formation of glands.</b>&mdash;Under this name are associated a number of
+(generally) rudimentary organs very different in their morphological
+nature and significance, and also in their functions. Some are truly
+glandular or secreting organs, while others have no visible office.
+Anything like a complete account of these structures would be out of
+place, and reference is only made to them here on account of the
+occasional existence of intermediate forms, which throw light on the
+morphological significance of these structures. Thus, in <i>Passiflora</i>
+and <i>Viburnum Opulus</i>, the so-called glands on the sides of the petiole
+appear to represent leaflets, and are not unfrequently developed as
+such.</p>
+
+<p>M. Dunal observed a flower of <i>Cistus vaginatus</i> in which some of the
+stamens were replaced by an hypogynous disc.<a name="FNanchor_547_547" id="FNanchor_547_547"></a><a href="#Footnote_547_547" class="fnanchor">[547]</a> Moquin has seen

+<i>Drosera intermedia</i>, which go to show that the ovules are homologous
+with the glandular hairs on the margins of the leaves of these plants,

+<h2><a name="GENERAL_CONCLUSIONS" id="GENERAL_CONCLUSIONS"></a>GENERAL CONCLUSIONS.</h2>
+
+
+<p>At the end of many of the preceding sections, and whenever the
+requirements of the case demanded it, a brief summary of the main facts
+and of the inferences to be derived from them has been given. It may be
+useful to give in conclusion a few general remarks on the whole subject.</p>
+
+<p>It will be seen from the numerous facts herein cited, that the so-called
+monstrous formations (excluding morbid growths the result of disease or
+injury) present no peculiarities absolutely foreign to the normal
+organisation of plants. The difference between the natural and monstrous
+development is one of degree and frequency of occurrence, not of kind.</p>
+
+<p>Deviations from the customary form have been shown to arise from
+excessive or diminished growth, or from arrested or exalted development.
+Even in those instances where, for convenience' sake, the term perverted
+development has been used, it must be understood as applying only to the
+particular plant or organ under consideration, as the form assumed is
+perfectly in accordance with the ordinary conformation of some other
+plant or group of plants.</p>
+
+<p>The period at which malformations occur is a matter of some importance;
+this is, indeed, implied in the term arrest of development; evolution
+goes on with<span class='pagenum'><a name="Page_476" id="Page_476">[Pg 476]</a></span> growth up to a certain point and is then stopped, and thus
+changes are brought about in the part affected of a different nature
+from those dependent on non-development or suppression.</p>
+
+<p>Some malformations are congenital, therefore, while others are
+acquired&mdash;in the former instance the disturbance is coeval in origin,
+and contemporaneous in its growth and development, with those of the
+affected part; in the latter case the organ may have attained its
+ordinary degree of perfection, or at least may have advanced some way
+towards it, before any deviation shows itself. True chorisis or fission,
+for instance, is usually a congenital affection, arising at a very early
+period of development, while enation takes place from structures which
+are all but complete as to their organisation, even though they may not
+have attained their full dimensions. The date of appearance is also of
+consequence in determining the true nature of some changes; it does not
+always follow, for instance, that because one organ occupies the
+position of another, it is of the same nature as the one whose place it
+fills. The presence of anthers on petals or on such organs as the corona
+of <i>Narcissus</i> does not necessarily constitute those parts actual
+stamens, but rather staminodes. The true stamens are either wanting, or
+if present, they are in advance of their imitators as regards their
+development.</p>
+
+
+
+<p><b>General morphology of the leaf and axis. Homology.</b> Since the time when
+Goethe's generalisations were adopted by A. P. De Caudolle, special
+attention has been given to the form and mode of development of the
+leaf-organ; for as it was well said by Wolff, if once the course of
+evolution and the structure of the leaf were<span class='pagenum'><a name="Page_477" id="Page_477">[Pg 477]</a></span> known, those of the parts
+of the flower would follow as a matter of course.</p>
+
+<p>It is not necessary, in this place, to pursue the subject of the
+development and construction of the leaf further than they are
+illustrated by ordinary teratological phenomena.</p>
+
+<p>From this point of view perhaps the most interesting circumstance is the
+part that the sheath of the leaf plays.<a name="FNanchor_553_553" id="FNanchor_553_553"></a><a href="#Footnote_553_553" class="fnanchor">[553]</a> In many cases of so-called
+metamorphosis, it is the sheath of the leaf that is represented and not
+the blade. In normal anatomy the sepals, petals, carpels, and even the
+stamens, as a general rule, correspond to the sheath rather than to the
+blade of the leaf, as may be seen by the arrangement of the veins. The
+blade of the leaf seems to be set apart for special respiratory and
+absorbent offices, while the sheath is in structure, if not in office,
+more akin to the stem. It would not be easy apart from their position to
+distinguish between a tubular sheathing leaf and a hollow stem. The
+development of adventitious growths by chorisis or enation has been
+frequently alluded to in the foregoing pages, and many illustrations
+have been given of the power that leaves have of branching in more than
+one plane, owing to the projection of secondary growing-points from the
+primary organ. These new centres of development are closely connected
+with the fibro-vascular system of the leaf, so that no sooner does a new
+growing point originate, than vessels are formed to connect the new
+growth with the general fibrous cord, <a href="#Page_355">see pp. 355</a>, <a href="#Page_445">445</a>. This leads M.
+Casimir De Candollo to consider the entire leaf as a composite
+structure. The morphological unit, says he, is the cellular protrusion
+or growing point (<i>saillie</i>) and its corresponding fibro-vascular
+bundle.<a name="FNanchor_554_554" id="FNanchor_554_554"></a><a href="#Footnote_554_554" class="fnanchor">[554]</a></p>
+
+<p>The identity, in a morphological point of view, of the leaves and the
+lateral parts of the flower is so<span class='pagenum'><a name="Page_478" id="Page_478">[Pg 478]</a></span> thoroughly recognised that little
+need be said on that score, save to repeat that the homology of the
+floral organs is usually not so much with the entire leaf as with its
+sheath.</p>
+
+<p>The most singular instances of morphological identity are those relating
+to the sexual organs. We have seen the gradual transition of stamens to
+pistils, and of pistils to stamens, the development of ovules on the
+edges of the anther, the co-existence of pollen with ovules on an
+antheroid body, and, stranger still, the actual development of pollen
+within the tissues of the ovule itself! From such facts, in addition to
+what we know of the relative position, internal structure, and mode of
+development of the organs, it is impossible to avoid coming to the
+conclusion that, however distinctly these parts may, under ordinary
+circumstances, be set apart for the performance of distinct functions,
+morphologically they are homologous.</p>
+
+<p>These ideas may be carried yet farther&mdash;the same sort of evidence, which
+is adduced in support of the morphological identity of leaves with the
+parts of the flower, may be advanced in confirmation of the opinion,
+that, morphologically, there is no distinction between axis and leaf.
+The leaf, according to this view, is a specialised portion of the axis
+set apart to do certain work, just as the petals, stamens, &amp;c., are
+leaves told off for distinct uses. It is unnecessary to refer to the
+intermediate productions linking the leaf-form to that of the axis, all
+that is requisite here is to point out the facts that teratology lends
+in support of these views. These may be summed up by the statement that
+almost all those attributes which morphologists recognise as peculiar to
+one or the other organ respectively, may be and are manifested by both.
+We have the stem acquiring the characters of the leaf, and the leaf
+those of the stem. Thus we have seen leaves, leaf-buds, branches, and
+flower-buds springing from leaves or leaf-organs;<a name="FNanchor_555_555" id="FNanchor_555_555"></a><a href="#Footnote_555_555" class="fnanchor">[555]</a> <a href="#Page_174">see pp. 174</a>, <a href="#Page_177">177</a>,
+445, &amp;c. The structure that we<span class='pagenum'><a name="Page_479" id="Page_479">[Pg 479]</a></span> are apt to associate exclusively with
+one is found to pertain to the other. The arrangement of the vascular
+cords in the leaf-organ finds its counterpart in the axis, generally, it
+is true, modified to suit altered circumstances or diverse purposes. In
+some cases the disposition is absolutely indistinguishable in the two
+organs. It may then be said that the distinctions usually drawn between
+axis and leaf are not absolute, and that, however necessary such a
+separation may be for descriptive or physiological purposes,
+morphologically the two organs are identical. Again, it may be said that
+leaf and axis are two phases of the same organ,&mdash;an organ capable of
+existing in its undifferentiated state in the form of a thallus among
+Cryptogams, but which in the higher groups of plants becomes marked out
+into separate portions, each portion having its own distinct functions
+to fulfil for the common benefit of the whole organisation.<a name="FNanchor_556_556" id="FNanchor_556_556"></a><a href="#Footnote_556_556" class="fnanchor">[556]</a></p>
+
+
+
+<p><b>Special morphology.</b>&mdash;Under this heading brief reference may be made to
+some of the organs whose morphological nature has been, and still is,
+much contested. It is clear that for the due elucidation of these
+matters, development and the comparative investigation of similar
+structures in different plants must be studied. Teratological data by
+themselves can no more be trusted to give a correct solution of any
+particular question, than the evidence furnished by other departments of
+botanical science taken separately. With this statement by way of
+caution, allusion may be made to some of the organs whose morphological
+construction is illustrated by the facts recorded in the present
+volume.</p><p><span class='pagenum'><a name="Page_480" id="Page_480">[Pg 480]</a></span></p>
+
+
+
+<p><b>Calyx-tube.</b>&mdash;In descriptive botany it is the common practice to speak of
+a calyx-tube, by which is meant a tubular or sheathing portion at the
+base of the flower, below the sepals or calyx-lobes, and distinct or
+inseparable from the ovary. The question morphology has to solve is
+whether this tubular structure is to be considered as a portion of the
+axis, or whether it is to be regarded as composed of the confluent bases
+of the sepals.</p>
+
+<p>Mr. Bentham, who has recently reviewed the evidence as to the nature of
+the calyx-tube in his paper on <i>Myrtace&aelig;</i>,<a name="FNanchor_557_557" id="FNanchor_557_557"></a><a href="#Footnote_557_557" class="fnanchor">[557]</a> still holds to the
+notion that the "calyx-tube" or "hypanthium" is formed from the
+concretion of the basal portions of the sepals. He founds his
+conclusions upon such facts as the following: the circumstance that the
+point of origin of the leaf is not always the same as the point of
+disarticulation or separation from the axis, inasmuch as the basal
+portion of the leaf is often adherent to the stem for some distance,
+though still recognisable as foliar not axial in its nature. In the same
+manner, the corolla and andr&oelig;cium may be concrete at the base, so
+that the stamens are for convenience' sake described as inserted into
+the tube of the corolla, though it is generally admitted that both
+stamens and petals are really hypogynous, and it is not usual to
+consider the corolla-tube up to the divergence of the stamens as part of
+the receptacle. A similar remark applies to the carpels and placentas.
+Mr. Bentham further considers that the gradual disconnection of the
+various whorls, that may be traced in many plants, is a further proof of
+concretion, rather than of expansion of the axis, but this argument may
+fairly be met by the consideration that the several whorls emerge at
+different heights.<a name="FNanchor_558_558" id="FNanchor_558_558"></a><a href="#Footnote_558_558" class="fnanchor">[558]</a></p>
+
+<p>Organs originally free and distinct become ultimately combined at the
+base by the gradual protrusion from<span class='pagenum'><a name="Page_481" id="Page_481">[Pg 481]</a></span> the receptacle of a ring or tube
+under them, as in the stamens of <i>Leguminos&aelig;</i>; yet, says Mr. Bentham, no
+one would propose to describe the staminal tube of monadelphous
+<i>Leguminos&aelig;</i> as part of the receptacle and not of the stamens. Perhaps
+not, for descriptive purposes, but morphologically it would not be easy
+to separate such a tube from the receptacle. The principal kinds of
+malformation which have a bearing on this subject are mentioned at pp.
+77&ndash;81 and 247, from which it may be seen that the evidence furnished by
+teratology is conflicting. It would seem, indeed, that while in some
+families of plants there may be a real calyx-tube, in others the tubular
+portion is a sheath-like prolongation of the axis. In <i>Primula</i> or
+<i>Pedicularis</i>, where the venation is clearly laminar, the tubular
+portion is distinctly calycine. In other cases the so-called calyx-tube
+seems as certainly to be an expansion of the receptacle, as in
+<i>Rosace&aelig;</i>, <i>Myrtace&aelig;</i>, <i>Melastomace&aelig;</i>, <i>Passiflora</i>,<a name="FNanchor_559_559" id="FNanchor_559_559"></a><a href="#Footnote_559_559" class="fnanchor">[559]</a> &amp;c.</p>
+
+<p>Where the petals and stamens are described as being inserted into the
+throat of the calyx, or are perigynous, it may be assumed as a general
+rule, subject to but few exceptions, that the so-called calyx-tube is
+really a portion of the receptacle.<a name="FNanchor_560_560" id="FNanchor_560_560"></a><a href="#Footnote_560_560" class="fnanchor">[560]</a> After all, this is very much a
+question of words, and for the following reasons,&mdash;very often the base
+of the calyx does evidently form a tube, and no one can say where the
+calyx ends and the receptacle begins. Again, many leaves are known to
+originate in the form of a ring-like protrusion from the axis, and from
+this primary ring originate secondary developments. Thus the asserted
+difference between a leaf, with such a history of development, and an
+axial structure becomes obliterated. From this point of view, peltate
+leaves like those of <i>Trop&aelig;olum</i> or <i>Nelumbium</i> become very significant.
+In both the leaf-stalk is cylindrical and traversed, as in the case of
+all cylindrical<span class='pagenum'><a name="Page_482" id="Page_482">[Pg 482]</a></span> leaf-stalks, by a circle of fibro-vascular cords, as in
+a branch, and which radiate in all directions in the blade of the leaf.
+Now, if (as often happens to a slight extent) the central portion of the
+leaf were much depressed, owing to the disproportionate growth of the
+peripheral, as contrasted with the central portions, we should have a
+funnel-like or tubular formation, precisely similar to many of the
+so-called calyx-tubes. And, if we further suppose new growths to
+originate from the sides of this funnel or tube, by chorisis or enation,
+we should have the homologue of a tubular calyx, to the inner surface of
+which are attached petals, stamens, &amp;c. From the consideration of
+circumstances such as these just detailed, together with that of the
+arrangement of the vascular cords, M. Casimir De Candolle arrives at the
+conclusion that the calyx-tube is a ring-like projection from an axis
+whose further direct development is arrested. The secondary projections
+or growing-points correspond to the several fibro-vascular cords of the
+primary ring, and are ultimately developed into sepals, petals, stamens
+and ovaries (<a href="#Page_384">see pp. 394</a>, <a href="#Page_509">509</a>).</p>
+
+
+
+<p><b>Andr&oelig;cium.</b>&mdash;The main points of morphological interest relating to the
+andr&oelig;cium, referred to in this volume, are those concerning the
+structure of the anther (<a href="#Page_292">see p. 292</a>), the compound nature of the stamens
+in some orders (<a href="#Page_294">see pp. 294</a>, <a href="#Page_345">345</a>), and the nature of the andr&oelig;cium in
+orchids (<a href="#Page_380">see p. 380</a>).</p>
+
+
+
+<p><b>Inferior ovary.</b>&mdash;Is the pistil always foliar in its morphological
+nature, or is it, in some cases, as Schleiden taught, formed from the
+axis alone? To a great extent the reply to this question is dependent on
+the conclusions that may be arrived at as to the true nature of the
+calyx-tube. Considered from a teratological point of view, there is no
+reason for considering the inferior ovary to be purely axial. On the
+contrary, the evidence derived from this source supports the ordinary
+opinion<span class='pagenum'><a name="Page_483" id="Page_483">[Pg 483]</a></span> that the carpels are invaginated within the expanded top of the
+flower-stalk and more or less adherent to it. Some of the gourds afford
+good illustrations of this, the upper part of the carpels in these
+fruits projecting beyond the axial portion. But this matter loses much
+of its importance if the morphological identity of axis and leaf-organ
+be conceded. The carpels in inferior ovaries seldom or never correspond
+to the lamina of the leaf, and between the vaginal portion of the
+carpellary leaf, and the axis who shall draw the distinction?</p>
+
+
+
+<p><b>Placentation.</b>&mdash;Some botanists have considered the placentas to be
+portions of the carpel, and have compared the production of ovules on
+them to the formation of buds on the leaf of <i>Bryophyllum</i>. Others have
+been led to see in each placenta, even when it is, to all outward
+appearance, a portion of the carpellary leaf, a direct prolongation from
+the axis, adherent to the leaf. Teratology shows that ovules may be
+formed indifferently on leaf-organs or on stem-organs. Sutural,
+parietal, axile, free-central placentation, and, if there be more forms,
+all may be met with even in the same ovary (<a href="#Page_96">see pp. 96</a>, <a href="#Page_508">508</a>). Now, if
+there were such special tendencies in the axis, as contrasted with the
+leaf, to produce ovules, it is hardly likely that such anomalous
+arrangements as those just mentioned would be as frequent as they are.
+But as leaves produce other leaves, from their edges or their surfaces,
+and as they form buds in the same situations, just as axial organs
+do,<a name="FNanchor_561_561" id="FNanchor_561_561"></a><a href="#Footnote_561_561" class="fnanchor">[561]</a> there is surely little ground for considering the placentas, or
+ovuliferous portions of the plant, to be of necessity axial. Here again,
+much of the difficulty vanishes if the morphological<span class='pagenum'><a name="Page_484" id="Page_484">[Pg 484]</a></span> identity of the
+leaf-form and of the stem-form be admitted.</p>
+
+
+
+<p><b>Structure of the ovule.</b>&mdash;The nature of the ovule and of its coverings
+has been a fertile source of controversy. The teratological data bearing
+on this subject have been given at pp. 262&ndash;272. These data strongly
+support the notion of the foliar nature of the coatings, and of the
+axial nature of the nucleus, taking leaf and axis either in the ordinary
+sense, or as modifications one of the other. It has been shown that the
+ovular coats may themselves become carpels, and that ovules may be
+developed upon ovules, p. 268. Whether the intra-carpellary siliques of
+<i>Cheiranthus</i>, not uncommonly met with (p. 182), are instances of ovular
+transmutation may be open to doubt.</p>
+
+<p>The axial nature of the nucleus has been inferred from its position,
+mode of growth, and from its occasionally lengthening into a leafy or
+even a floriferous shoot. Probably it may occasionally be invested by
+sheathing coats, more analogous to tubular processes from the
+receptacle, than to foliar organs, as is the case in <i>Welwitschia</i>. The
+discussion of this matter, however, pertains rather to normal morphology
+than to teratology.</p>
+
+
+
+<p><b>Morphology of conifers.</b>&mdash;The nature of the pseudo-leaves of
+<i>Sciadopitys</i>, and probably of other Conifers, is illustrated by
+teratology, as also is the true constitution of the scale of the cone
+(<a href="#Page_192">see pp. 192</a>, <a href="#Page_245">24</a>5, <a href="#Page_352">352</a>), though it must be admitted that little or no
+light is thrown on that much-contested point&mdash;the true nature of the
+ovule of Gymnosperms.</p>
+
+
+
+<p><b>Relative position of organs.</b>&mdash;When organs are considered, not
+separately, but in their relations to each other, the appearances
+presented are referable to similar causes. Thus, the separation of parts
+usually united has been shown to depend on an excess of<span class='pagenum'><a name="Page_485" id="Page_485">[Pg 485]</a></span> development,
+the persistent union of parts, usually separate in the adult state, has
+been traced to an arrest of the process of development, by no means
+necessarily coexistent with diminished growth. The diminished or
+increased number of parts is, in like manner, attributable to analogous
+causes, as also are the variations in arrangement and form, spoken of
+under the heads of Displacement, Peloria, Substitution, &amp;c.</p>
+
+<p>In the instance of displacements, it has been shown how slight a change
+is required to transform the so-called inferior ovary into a superior
+one. A defective development of the top of the flower-stalk in some
+cases, in others a lack of union between the tube of the receptacle or
+of the calyx (comprising in those terms not only the apex of the
+receptacle, but the base of the sepals) and the carpels, suffice to
+bring about this change in a character which for systematic purposes is
+of great value.</p>
+
+
+
+<p><b>Law of alternation.</b>&mdash;The circumstances that interfere with the law of
+alternation may be briefly alluded to. The deviations from the customary
+arrangement have been very generally attributed to suppression, or to
+chorisis. It is unquestionable that either of these affords an efficient
+explanation of the arrangement in question, as also does that
+modification of chorisis, as it may be considered, which has been
+treated of under the head of Enation. Spiral torsion of the axis would
+likewise bring about analogous results. Still, it is quite conceivable
+that opposition or superposition of organs may occur without the
+intervention of any such operations. This will be the more readily
+conceded when it is remembered that the phyllotaxis of leaves not
+unfrequently varies on different branches of the same individual tree,
+and that a similar variation in the flower would at once disturb the
+customary alternate arrangement. Coalescence of the vascular bundles in
+an unusual manner, and an irregular disposition<span class='pagenum'><a name="Page_486" id="Page_486">[Pg 486]</a></span> of these cords have
+also been considered to bring about deviations from the rule of
+alternation, but in general the formation of the cords is subsequent to
+that of the growing points or mamelons.</p>
+
+<p>Adhesions, accompanied by displacements, occasionally produce similar
+deviations, the nature of which is usually easily detected.</p>
+

+
+<p><b>Co-relation.</b>&mdash;The importance of this subject first prominently brought
+into notice by Geoffroy St. Hilaire gains in force daily. Rarely is a
+malformation an isolated phenomenon, almost always it is associated,
+from the operations of cause or effect, with some others. Instances of
+this co-relation have been cited in the preceding pages, and many more
+might have been mentioned, had the consideration of the relationship
+between form and function formed part of the plan of this volume. A
+change in itself slight, often acquires importance from its association
+with other alterations. This is particularly well seen in the case of
+the receptacle. Let an ordinarily concave thalamus remain, from
+defective development, flat, and how great the change in the appearance
+of the flower. Let the usually contracted receptacle be lengthened, and
+the whole aspect of the flowers so affected is altered to such an extent
+that, were their history not known, botanists would have no hesitation
+in assigning them to widely separate groups in their schemes of
+classification. Peloria, too, of either form, affords excellent
+illustrations of the co-existence of one changed condition with another.
+Not only is the form of one set of organs altered, but the number, the
+relative proportion, and the direction of the other organs of the flower
+are altered likewise.<a name="FNanchor_562_562" id="FNanchor_562_562"></a><a href="#Footnote_562_562" class="fnanchor">[562]</a> Not only is the whole symmetry changed, but
+the physiological operations carried on in the flower undergo
+corresponding alterations. </p><p><span class='pagenum'><a name="Page_487" id="Page_487">[Pg 487]</a></span></p>
+
+<p>There are certain co-relations which do not appear to have hitherto
+attracted the attention they merit; such, for instance, is that which
+exists between the particular period at which an organ is developed and
+its position and form. In normal morphology this has, to some extent,
+been worked out, as in the case of definite and indefinite, centrifugal
+and centripetal inflorescences, and in the definite or indefinite
+formation of shoots, &amp;c.</p>
+
+<p>Other instances may be cited in the frequent co-existence of regular
+flowers and definite inflorescence, the terminal position of many
+peloriated flowers, the relationship between indefinite inflorescence
+and prolongation of the axis, &amp;c.</p>
+
+<p>Again, the simultaneous evolution of the parts of the flower and their
+consequent verticillate arrangement, are often associated with the
+production of different forms from those characteristic of organs
+developed in succession, and, in consequence, arranged spirally. In the
+case of simultaneous development we meet with a repetition of whorls, as
+in what are termed hose-in-hose flowers (flores duplicati, triplicati,
+&amp;c.), and also with cases of peloria. In instances where the organs are
+formed successively in spiral order, we meet with such changes as median
+prolification, petalody, and phyllody. All these are alterations which
+we might anticipate from the activity of the growing point being checked
+at a certain stage in the one case, while it is continuous in the other.
+This relationship between the definite and indefinite modes of growth
+and the form of the several organs of the flower, is more constant in
+reality than it may appear to be from a perusal of the lists of genera
+in the foregoing pages, in which it was not possible to show
+sufficiently well the comparative frequency of any given changes in
+individual plants. Had it been possible to give statistics setting forth
+the frequency of certain deviations in plants or groups having a
+particular organisation, as compared with the rarity of their occurrence
+in other plants of a different<span class='pagenum'><a name="Page_488" id="Page_488">[Pg 488]</a></span> conformation, these co-relationships
+would have been rendered much more evident. A hundred different plants,
+for instance, may be named in any particular list, of which fifty shall
+be of one type of structure, and the remainder of another. And the
+co-relative changes in each fifty may appear to be evenly balanced, but
+so far is this from being the case, that the frequency of the occurrence
+of a particular change, in one species in the list, may be so great as
+far to exceed the instances of its manifestation in all the rest put
+together. This difficulty is only very partially obviated by the
+addition of the * to signify especial frequency of occurrence of any
+given malformation in the plants to whose names it is affixed.</p>
+
+
+
+<p><b>Compensation.</b>&mdash;But little further need be said on this head. An
+atrophied condition of one part is generally associated with an
+hypertrophied condition of another, and scarcely a change takes place in
+one direction, but it is associated with an inverse alteration in some
+other. This principle is not universal, and its application must not be
+unduly strained. It requires specially to be considered in reference to
+differences in the degree or kind of functional activity exercised by
+the organs implicated&mdash;points beyond the scope of the present volume.</p>
+
+
+
+<p><b>Teratology and classification.</b>&mdash;Lastly, there remain to be mentioned the
+bearings of teratology on systematic botany. There are those who would
+entirely exclude teratology from such matters. It may be expedient to do
+so when the object sought is one of convenience and facility of
+determination only, but when broader considerations are concerned,
+teratology must no more be banished than variation. In most instances
+the one differs but in degree from the other. If variation affords aid
+in our speculations as to the affinities and genealogical descent of
+species and other groups, so does teratology, and in a far higher
+degree.</p><p><span class='pagenum'><a name="Page_489" id="Page_489">[Pg 489]</a></span></p>
+
+<p>Take the characters of exogens as distinct from endogens; even under
+ordinary circumstances, no absolute distinction can be drawn between
+them. There are plants normally of an intermediate character, while, to
+take exceptional instances, there are exogens with the leaves and
+flowers of endogens, and endogens whose outward organisation, at any
+rate, assimilates them to exogens. Diclinous or monochlamydeous plants
+owe their imperfect conformation to suppression, and may become
+structurally complete by a species of peloria. Structurally
+hermaphrodite flowers become unisexual by suppression, or are rendered
+incomplete by the non-development of one or more of their floral whorls.
+Hypogynous flowers become perigynous by adhesion, or by lack of
+separation; perigynous ones become hypogynous by an early detachment
+from the receptacle that bears them, or by the arrested development of
+an ordinarily cup-like receptacle.</p>
+
+<p>How the relative position of the carpels and the calyx may be altered
+has already been alluded to, as has also the circumstance that while it
+is common to find an habitually inferior or adherent ovary becoming
+superior or free, it is much more rare to find the superior ovary
+adherent to the receptacle or to the calyx.<a name="FNanchor_563_563" id="FNanchor_563_563"></a><a href="#Footnote_563_563" class="fnanchor">[563]</a> Regular and irregular
+peloria, too, serve to show how slight are the boundaries, not only
+between different genera, but also between different families.</p>
+
+<p>While, therefore, teratology may be an unsafe guide in strictly
+artificial schemes, it is obvious that its teachings should have great
+weight in all philosophical systems of classification.</p>
+
+<p>The questions will constantly arise, does such and such a form represent
+the ancestral condition of certain plants? Is it a reversion to that
+form? or is it, on the other hand, the starting point of new forms?</p><p><span class='pagenum'><a name="Page_490" id="Page_490">[Pg 490]</a></span></p>
+
+<p>Such questions cannot receive at present any satisfactory answer, but
+the evidence we have seems to indicate that pre-existing forms were
+simpler, and less specialised in structure than those now existing, and
+hence if we meet with malformations of a simple kind, we may consider
+them as possible reversions; while, if they present features of
+increased complexity, and more sharply defined differentiation, we may
+assume them to be evidences of a progressive rather than of a
+retrogressive tendency.</p>
+
+<p>That monstrosities so called may become the starting points of new forms
+is proved by circumstance that, in many cases, the peculiarities are
+inherited so that a new "race" is produced and perpetuated: and if a new
+race, why not a new species? The difference is one of degree only.</p>

+DOUBLE FLOWERS.<a name="FNanchor_564_564" id="FNanchor_564_564"></a><a href="#Footnote_564_564" class="fnanchor">[564]</a></h2>
+
+
+<p>In ordinary language, the epithet double flowers is applied to flowers
+of very varied structural conformation. The most common conditions
+rendering a flower double, in the popular acceptation of the term, are
+substitutions of petals or petal-like bodies for stamens and pistils,
+one or both. (See Petalody, p. 283.) Another very common mode of
+doubling is brought about by a real or apparent augmentation in the
+number of petals, as by multiplication, fission, or chorisis. (See pp.
+66, 343, 371, 376.) Sometimes even the receptacle of the flower within
+the outer corolla, divides, each subdivision becoming the centre of a
+new series of petals, as in some very luxuriant camellias and anemones.
+The isolation of organs which, under ordinary circumstances, are united
+together, is another circumstance, giving rise, in popular parlance, to
+the use of the term double flower. (See Adesmy, Solution, pp. 58, 76,
+82.) Prolification is another very frequent occurrence in the case of
+these flowers, while still other forms arise from laciniation of the
+petals, or from the formation of excrescences from the petals or
+stamens, in the form of supplementary petal-like lobes. (See Enation, p.
+443.)</p>
+
+<p>As these matters are all treated of under their respective headings, it
+is not necessary to allude to them again in detail. It may be well,
+however, to allude, in general terms, to the causes which have been
+assigned by various writers for their formation, and to the means which
+have been adopted by practical experimenters to secure the production of
+the flowers often so much esteemed by the florist. It must be admitted
+that, in spite of all that has been written on the subject, but very
+little is known about these matters. In the case of the stock the
+following means have been adopted by cultivators in order to<span class='pagenum'><a name="Page_492" id="Page_492">[Pg 492]</a></span> obtain
+plants bearing double instead of single flowers. There is first the
+crossing of single flowers with double ones, effected by planting a
+double-flowered plant in proximity to a single-flowered one; but this,
+it is obvious, could lead to no important results, since the double
+flowers, having no pollen, could not possibly influence the seed, which
+is borne only by the single-flowered plants. Another plan is the
+degustation of the buds, that is to say, the chewing of the well-formed
+buds; it is held that the single plants can be recognised by their
+sweeter taste and greater consistence, and may thus be weeded out; but
+there is at least the disadvantage attending this method, that the
+plants, single as well as double, must all be grown up to the period
+when these buds are tolerably well advanced. A third method which has
+been adopted is, that of sowing the seeds at a particular lunar epoch,
+great confidence being placed in the plan of planting them during the
+last quarter of the moon, but such confidence is found to be misplaced.
+The plan of removing the stamens has had its supporters, but as this
+must be done at an early stage of development, and could only influence
+the result by diverting the vital force which would be expended in the
+maturation of the pollen, to the perfecting of the seeds, it is obvious
+that the plan is impracticable for all ordinary purposes, even if in any
+degree efficient, which from the plasticity of vegetable development,
+and the faculty of doubling which is inherent in the stock family, is
+not at all improbable. Still another mark, the presence of a fifth petal
+in the single or seed-bearing flower, has been held to indicate the
+assurance of obtaining a crop of double-flowered plants from seeds saved
+from flowers possessing this peculiarity. To a certain extent,
+doubtless, this expectation would be realised, owing to the plasticity
+and inherent quality just alluded to, but the proportion would be too
+small for any useful practical purpose.</p>
+
+<p>"The gardeners of Erfurt," observes M. Chat&eacute;, who has written a
+book<a name="FNanchor_565_565" id="FNanchor_565_565"></a><a href="#Footnote_565_565" class="fnanchor">[565]</a> on the subject, in which he makes known a means of obtaining
+double-flowered stocks founded on more than fifty years' practice in his
+family, "have, for a long time, to a certain extent monopolised the sale
+of seeds of these plants. To obtain these seeds, the Erfurt gardeners
+cultivate the flowers in pots, and place them on shelves in large
+greenhouses, giving them only sufficient water to prevent them from
+dying. So cultivated the plants become weakened, the pods shortened, and
+the seeds less numerous, and better ripened; and these seeds give from
+60 to 70 per cent. of double flowers.</p>
+
+<p>"The seeds from these plants are said to be mostly of an abnormal shape,
+which is so striking that experienced cultivators are able to separate
+those which would furnish double flowers from those which would produce
+single ones."</p><p><span class='pagenum'><a name="Page_493" id="Page_493">[Pg 493]</a></span></p>
+
+<p>M. Chat&eacute;'s method, which he calls the French one, gives still greater
+results, viz.: 80 per cent. of double flowers, and these produced by
+very simple means. "When my seeds," he observes, "have been chosen with
+care, I plant them, in the month of April, in good dry mould, in a
+position exposed to the morning sun, this position being the most
+favourable. At the time of flowering I nip off some of the flowering
+branches, and leave only ten or twelve pods on the secondary branches,
+taking care to remove all the small weak branches which shoot at this
+time. I leave none but the principal and the secondary branches to bear
+the pods. All the sap is employed in nourishing the seeds thus borne,
+which give a result of 80 per cent. of double flowers. The pods under
+this management are thicker, and their maturation is more perfect. At
+the time of extracting the seeds the upper portion of the pod is
+separated and placed aside, because it has been ascertained that the
+plants coming from the seeds situated in this portion of the pod, give
+80 per cent. of single flowers. They yield, however, greater variety
+than the others. This plan of suppressing that part of the pod which
+yields single flowers in the largest proportion, greatly facilitates the
+recognition of the single-flowered plants, because there remains to be
+eliminated from among the seedlings only from 10 to 15 per cent.</p>
+
+<p>This separation of the single from the double-flowered plants, M. Chat&eacute;
+tells us is not so difficult as might be supposed. The single stocks, he
+explains, have deep green leaves (glabrous in certain species), rounded
+at the top, the heart being in the form of a shuttlecock, and the plant
+stout and thickset in its general aspect, while the plants yielding
+double flowers have very long leaves of a light green colour, hairy, and
+curled at the edges, the heart consisting of whitish leaves, curved so
+that they enclose it completely. Such is the substance of M. Chat&eacute;'s
+method of securing so large a proportion of double-flowered plants, and
+then of separating them from the remaining single ones&mdash;a method which
+commends itself to the good sense of the intelligent cultivator."<a name="FNanchor_566_566" id="FNanchor_566_566"></a><a href="#Footnote_566_566" class="fnanchor">[566]</a></p>
+
+<p>Signor Rigamonti, a great cultivator of pinks, asserted that he was able
+to distinguish double from single-flowered pinks, in the seedling state.
+According to this gentleman, those seedlings which produce three
+cotyledons in a whorl in place of two, form double flowers. In the case
+of <i>Primula sinensis</i> the same results occurred. Some had three leaves
+in a ring, others two; most had the leaves standing one over the other
+as usual. These were divided into three sets, and when they flowered,
+the first lot were all double, the second semi-double, the third single.
+But these statements have not been confirmed by other observers; and the
+writer can safely assert that seedling pinks occasionally<span class='pagenum'><a name="Page_494" id="Page_494">[Pg 494]</a></span> produce three
+cotyledons, and subsequently single flowers. He has never observed a
+double flower under these circumstances, though it is true his
+experience in this matter has been but small.</p>
+
+<p>A writer in Otto's 'Gartenzeitung,' considers that double flowers are a
+consequence of dryness of soil and atmosphere, and not of a luxurious
+soil, rich in nutritious matter, having arrived at this conclusion from
+an observation of the following circumstances:</p>
+
+<p>"Fifty years ago we saw <i>Kerria japonica</i> in a hothouse with single
+flowers. Twenty years later we met with it in several gardens, in the
+open air, but always with double flowers. At this time we were assured
+that single-flowered plants were no more to be found in the whole of
+Europe, and botanists forming herbaria offered considerable sums for a
+branch of <i>K. japonica</i> with single flowers. We were requested to take
+the plant in hand for the purpose of inducing it to produce single
+flowers. We were advised to plant it out in a rich soil, which was done,
+but, by chance, the situation was sloping, consequently it did not
+retain moisture, and all the flowers produced for several years in
+succession were double. Shortly after, the captain of an English ship
+again brought plants bearing normal flowers from Japan, which were soon
+spread over the continent, and of which we received one plant. After
+three years all the young plants raised from cuttings were
+double-flowered.</p>
+
+<p>"In the year 1820 we several times visited a garden in the neighbourhood
+of Vienna, well known on account of its plant culture. The gardener
+there possessed an immense plant of <i>Camellia japonica</i> with single
+flowers, and some small plants raised from this by cuttings, but no
+other variety of camellia. He fertilised the flowers with their own
+pollen, harvested seeds, which he sowed, and the plants raised from them
+were placed in an extremely dry, lofty conservatory, where, after some
+years, instead of producing single flowers, they all produced double
+ones. The seedlings and mother plant were planted in one and the same
+kind of earth, and some of the flowers on the old plant also showed an
+inclination to become double.</p>
+
+<p>"This, at that time, to us, enigmatical phenomenon, was kept in mind
+until we had an opportunity of instituting comparisons between the
+climate of Japan and China and our own, and we then concluded that in
+the case of a plant imported from thence, and exposed to such different
+climatical influences, the origin of the greater or less imperfection of
+its sexual organs was probably owing to this change, as we had
+experienced in <i>Kerria</i> and <i>Camellia</i>; and that the sterility of many
+other exotic plants might be attributed to the same cause. The
+difference in the climatical relations of Japan and Europe is very
+considerable. In Japan, previous to the new growth of <i>Kerria</i> and
+<i>Camellia</i>, a rainy season of three months' duration prevails; in
+Europe, on the contrary, dry winds prevail especially in the eastern
+part, where our plains are<span class='pagenum'><a name="Page_495" id="Page_495">[Pg 495]</a></span> often transformed into deserts. Is it,
+therefore, remarkable that a plant introduced from Japan into Europe,
+exposed to the influences of this great diversity of climate, should
+produce imperfect sexual organs incapable of further propagating the
+plant from seeds? A rich soil, with the necessary amount of moisture,
+will never engender double flowers."<a name="FNanchor_567_567" id="FNanchor_567_567"></a><a href="#Footnote_567_567" class="fnanchor">[567]</a></p>
+
+<p>Mr. Darwin<a name="FNanchor_568_568" id="FNanchor_568_568"></a><a href="#Footnote_568_568" class="fnanchor">[568]</a> describes a peculiar form of <i>Gentiana Amarella</i>, in
+which the parts of the flower were more or less replaced by compact
+aggregations of purple scales in great numbers. A similar condition is,
+indeed, not uncommon in this plant, and, as Mr. Darwin also remarked, on
+hard, dry, bare, chalky banks, thus bearing out the views expressed by
+the writer in the 'Gartenzeitung' just cited. Some double flowers of
+<i>Potentilla reptans</i> found growing wild near York, and transmitted to
+the writer by a correspondent, were observed growing along a high wall,
+in a dry border, close to a beaten path, bordering on a gravel pit,
+others were found on a raised bank, which, from its elevation and
+exposure to the sun, was particularly dry.</p>
+
+<p>On the other hand, the double-flowered <i>Cardamine pratensis</i>, which is
+occasionally found in a wild state, always grows in very wet places.</p>
+
+<p>Of late years a remarkable double-flowered race of <i>Primula sinensis</i>
+has been obtained. In particular, Messrs. Windebank and Kingsbury, of
+Southampton, have succeeded in raising a set of plants in which the
+flowers are very double and very attractive in a florist's point of
+view. The corollas in these flowers are not merely duplicated, but from
+their inner surface spring, in some cases, funnel-shaped or tubular
+petals (p. 315), so regular in form as quite to resemble a perfect
+corolla. These tubes are attached to the inner side of the tube of the
+corolla, in the same way as are the stamens, these latter organs being,
+it appears, absent. The carpels are present, but open at the top, and
+bear numerous ovules, hence it was at first surmised that these plants
+were obtained and perpetuated, by the application of pollen from single
+flowers to these double-flowered varieties.</p>
+
+<p>The raisers of this fine race however assert that "the double kinds are
+all raised from the seed obtained from <i>single</i> flowers; the double
+blooms do not produce seed, as a rule, and even if they did yield seed,
+and it were to germinate, the plants so raised would simply produce
+single flowers." Semi-double flowers will produce seed, but it is
+necessary that they should be fertilised with the pollen from the single
+blooms. They rarely, however, if ever, produce really double flowers
+when so fertilised, and the number of semi-double flowers, even, is
+always small, the remainder, and, consequently, the larger part, proving
+single. To obtain double varieties, the raiser fertilises certain fine
+and striking single flowers, with the pollen of other equally fine<span class='pagenum'><a name="Page_496" id="Page_496">[Pg 496]</a></span>
+single blooms, and the desired result is obtained. This is Messrs.
+Windebank and Kingsbury's <i>modus operandi</i>, the exact process or mode of
+accomplishment being, however, a professional secret.<a name="FNanchor_569_569" id="FNanchor_569_569"></a><a href="#Footnote_569_569" class="fnanchor">[569]</a></p>
+
+<p>From what has been said, as well as from other evidence which it is not
+necessary to detail in this place, it may be seen that the causes
+assigned by physiologists, and the plans proposed by cultivators for the
+production of double flowers, are reducible to three heads, which may be
+classed under Plethora, Starvation, and Sterility. These three seem
+inconsistent one with the other, but are not so much so as they at first
+sight appear to be.</p>
+
+<p>Tho advocates of the plethora theory have much in their favour: for
+instance, the greater frequency of double flowers among cultivated
+plants than among wild ones. The great preponderance of double flowers
+in plants derived from the northern hemisphere, when contrasted with
+those procured from the southern, as alluded to by Dr. Seemann, seems
+also to point to the effect of cultivation in producing these flowers.
+Now, although this is, to a large extent, due to the selection that has
+been for so long a period practised by gardeners, still that process
+will not account for the appearance of double flowers where no such
+selection has been exercised; as in the case of wild plants. Some double
+peas, observed by Mr. Laxton, appeared suddenly; they had not been
+selected or sought for, but they were produced, as it would appear, as a
+result of high cultivation, and during the period when the plant was in
+greatest vigour; and as the energies of the plant failed, so the
+tendency to produce double flowers ceased. Indeed, in reference to this
+subject, it is always important to bear in mind the time at which double
+flowers are produced; thus, an annual plant subjected to cultivation,
+will, it may be, produce single flowers for the firet year or two, then
+a few partially double flowers are formed, and from these, by careful
+selection and breeding, a double-flowered race may be secured.
+Sometimes, as in the peas before alluded to, in the same season the
+earlier blossoms are single, while later in the year double blossoms are
+produced. This happens, not only in annuals, but also in perennials, and
+is not infrequent in the apple; an illustration of this occurrence in
+this tree is given in the 'Gardeners' Chronicle' for 1865, p. 554.<a name="FNanchor_570_570" id="FNanchor_570_570"></a><a href="#Footnote_570_570" class="fnanchor">[570]</a>
+Sometimes the flowers on a particular branch are double, while those on
+the rest of the plant are single.<a name="FNanchor_571_571" id="FNanchor_571_571"></a><a href="#Footnote_571_571" class="fnanchor">[571]</a> On these points, the evidence
+furnished by a double white hawthorn in the Royal Botanic Gardens at
+Edinburgh is important. Professor<span class='pagenum'><a name="Page_497" id="Page_497">[Pg 497]</a></span> Balfour kindly wrote as follows in
+reply to an inquiry respecting this plant:&mdash;"A double white hawthorn in
+the Royal Botanic Gardens produced double flowers in spring. It retained
+its leaves during autumn and winter, until the following spring. It then
+flowered in the second spring, but produced weak single flowers only,
+and has continued to do so ever since. The flowering has been always
+weak, since this change of flowers from double to single. Mr. M'Nab
+attributes the change in the duration of the leaves to the filling up of
+the ground round the tree, to the height of a foot and a half on the
+stem. He is now trying the effect of extra manure in giving extra vigour
+to the plant." Here, at least, the production of single flowers would
+seem to be the result of debilitating causes, connected with the unusual
+persistence of the leaves, &amp;c., for while the tree was healthy, double
+flowers were produced.</p>
+
+<p>A similar illustration came under the writer's own notice. Some seedling
+balsams, of a strain which from long selection and hereditary tendency
+produces, year after year, double flowers were, in the spring (of 1866),
+allowed to remain in the seed-pans for many weeks after they were ready
+to be potted off; they were hence partly starved, and when they bloomed,
+they produced single flowers only. But these same plants, when more
+liberally treated, produced an abundance of double flowers. Moreover,
+other seedlings of the same batch, but sown later, and potted off at the
+usual time, produced double flowers as usual. Of a like character is the
+fact that the double <i>Ranunculus asiaticus</i> loses its doubleness if the
+roots are planted in a poor soil.</p>
+
+<p>On the other hand, the way in which double stocks are stated to be
+produced at Erfurt, viz.: by giving the plants a minimum supply of
+water, and the other circumstances alluded to as showing the connection
+between the production of double flowers, and a deficiency of water, as
+well as the experiments of Mr. Monro, go to show that, so far from
+plethora, the inducing cause must be more nearly allied to inanition,
+though the impoverishing process is, to a certain extent, counteracted
+by only allowing a few of the seed-pods to ripen, and thus concentrating
+in a small number of flowers the nutriment intended for many.</p>
+
+<p>Professor Edward Morren ('Bull. Acad. Roy. Belg.,' 2me ser., vol. xix,
+p. 224) considers the existence of true variegation in leaves, and the
+production of double flowers, as antagonistic one to the other; the
+former is a sign of weakness, the latter of strength. But it would seem
+that the exceptions are so numerous&mdash;so many cases of the co-existence
+of variegated leaves, and double flowers are known, at least in
+individual plants if not in species&mdash;that no safe inferences can be
+drawn as to this point. Since the above remarks were printed, Professor
+Morren has published a second paper on the subject, upholding his former
+views as to the incompatibility of variegated foliage (not mere
+colouration) and double flowers. In this paper he criticises the
+objections<span class='pagenum'><a name="Page_498" id="Page_498">[Pg 498]</a></span> raised by the present writer and others, and examines some
+of the alleged exceptions. Some of these the Belgian savant finds to
+prove his rule, inasmuch as although there is a co-existence of
+variegated foliage and double flowers in these illustrations, yet the
+plants are weakly, the flowers ill formed, or fall off before expansion.
+Admitting all this, there still remain cases in which double flowers and
+variegated foliage do exist in conjunction, and where the plants are
+vigorous and the flowers well developed. Instances of this are known to
+cultivators in species of <i>Dianthus</i>, <i>Hemerocallis</i>, <i>Alth&aelig;a</i>,
+<i>P&aelig;onia</i>, <i>Rosa</i>, <i>Ranunculus</i>, <i>Serissa</i>, <i>Saponaria</i>, etc., and
+probably the art of the cultivator would speedily be successful in
+raising other examples, were it a matter of importance or interest to
+them to do so. At any rate, the existence of a few unimpeachable
+illustrations is sufficient to support the opinion of the present
+writer, and objected to so strongly by M. Morren that, in the present
+state of our knowledge, "no safe inferences can be drawn" from the facts
+alluded to by the Belgian professor.<a name="FNanchor_572_572" id="FNanchor_572_572"></a><a href="#Footnote_572_572" class="fnanchor">[572]</a></p>
+
+<p>Mr. Darwin<a name="FNanchor_573_573" id="FNanchor_573_573"></a><a href="#Footnote_573_573" class="fnanchor">[573]</a> has thrown out the suggestion that the cause for the
+appearance of double flowers may be sought for in some previous state of
+things, bringing about sterility or imperfect formation, or functional
+activity of the genitalia of the flower, and consequent compensatory
+increase of the petaline element, either in the form of an increased
+number of bracts, petals, &amp;c., or in the substitution of petals for
+stamens and pistils, &amp;c.</p>
+
+<p>In considering these points the question arises whether they can be
+reconciled one with another. And there is little doubt but that they may
+be. The production of a flower is preceded by an arrest of vegetation;
+this is obvious: the current of the plant's life becomes changed, the
+growth of the leaves is checked, the lengthening of the branches is
+arrested as the flower-bud forms; moreover, there is a close
+relationship in a large majority of flowers between the outer envelopes
+of the flower and the scales of a leaf-bud; this is especially so in
+regard to the venation, and is admitted by all morphologists. So far,
+then, it may be said that the production of a flower, like that of a
+bud, is due to a diminution of vegetative action; and as in double
+flowers we have, for the most part, merely a repetition and exuberant
+formation of floral envelopes, so we may attribute their formation to a
+continuance of the same feeble vegetative action as that which produced
+the first or normal series. How, then, can a copious supply of rich
+food, such as is provided by cultivation, produce double flowers? To
+this question, according to our theory, the reply would be that the
+quantity of food is excessive, more than the plant can properly digest;
+and hence vegetative<span class='pagenum'><a name="Page_499" id="Page_499">[Pg 499]</a></span> action is stopped, at least partially&mdash;pretty much
+as it would be if the plant were placed in the opposite condition of
+starvation. The effect of supplying a plant (or an animal) with an
+excessive supply of food, which it cannot assimilate, is in many
+respects similar to that which results from partially cutting off the
+supplies. And the same reasoning applies to sterility. If by high
+culture, or the supply of an undue quantity of nourishment, the
+constitution of the plant be impaired, or if the plant be pampered, it
+is no wonderful thing that sterility should ensue. Hence, then, may it
+not be asserted as a general principle that in the production of double
+flowers a partial arrest of development, if not of growth, however
+produced, is an essential preliminary? All the attendant phenomena, such
+as the obliteration of the stamens, the augmentation in the number of
+floral whorls, the occurrence of prolification, are consistent with the
+supposition of a primary arrest of development, more or less complete,
+as the case may be: at one time permanent, at another time relaxed and
+intermittent, or in a third set of cases the vegetative activity or
+power of growth may be restored, and from the centre of the flower may
+spring a perfect branch with perfect leaves, the production of sheaths
+only being superseded by the development of leaves, in which all the
+parts&mdash;sheath, stalk, and blade&mdash;are present.</p>
+
+<p>When once the disposition to form double flowers is established, that
+tendency becomes hereditary: there are races of single Stocks in which,
+out of hundreds of plants, scarcely one double-flowered form is met
+with; but when the tendency to produce double blooms is set up, single
+flowers become the exception: thus, in the Balsams, before mentioned,
+not one in fifty now produces single flowers, and the seeds of these
+double Balsams produce double-flowered seedlings, with scarcely a
+"rogue" among them.</p>
+
+<p>The following list of plants producing double flowers of any kind is
+taken from that given in 'Seemann's Journal of Botany,' vol. ii, p. 177,
+and to which some additions have been made. Miscalled double flowers,
+such as those of the <i>Composit&aelig;</i>, <i>Viburnum Hydrangea</i>, &amp;c., are
+excluded.</p>

+first-named, the fasciation occurred in the inflorescence. In some
+species of <i>Artabotrys</i>, indeed, fasciation and curvation of the
+inflorescence are common.</p>
+
+<p><i>Synanthy</i> (<a href="#Page_39">p. 39</a>).&mdash;Several additional instances of adhesion of two or
+more flowers in <i>Calanthe vestita</i>, <i>C. Veitchii</i>, and other forms of
+this genus may be cited. These furnish further illustrations of the much
+greater liability of some plants to particular changes as compared with
+others. <i>Scilla bifolia</i>, <i>Gagea arvensis</i>, and <i>Viola odorata</i> may be
+added to the list of synanthic plants.</p>
+
+<p><i>Alterations of placentation, &amp;c.</i> (<a href="#Page_98">see pp. 98</a>, <a href="#Page_483">483</a>).&mdash;M. Casimir De
+Candolle, in a letter to the author, dated March 8th, 1869, thus writes
+of the existence of a double row of carpels in <i>Pyrus spectabilis</i> and
+<i>Crat&aelig;gus Oxyacantha</i>, "a longitudinal section of a double flower of
+<i>Pyrus spectabilis</i> shows two rows of carpels, placed one above another.
+The arrangement of the vascular bundles shows that the upper row is
+external in relation to the lower series. The carpels of the latter are
+wholly coalescent as in a pear, while those of the upper verticil are
+only partially coherent or sometimes quite distinct. The placentation is
+constantly axile in the inferior row and parietal in the upper one. The
+number of ovules in each carpel of the superior row varies greatly, and
+they are often, but not always, inserted in two longitudinal ranks, as
+is constantly the case in the lower carpels. Double flowers of <i>Crat&aelig;gus
+Oxyacantha</i> present the same anomalies." For analogous instances in
+<i>Digitalis</i>, <a href="#Page_98">see p. 98</a>. <a href="#Page_380">See also p. 380</a>, <i>Saxifraga</i>.</p>
+
+<p><i>Prolification</i>, <a href="#Page_120">p. 120</a>.&mdash;A. P. De Candolle, "Organographie V&eacute;g&eacute;tale,"
+tab. 40, figures an instance of suppression of one lobe of the ovary in
+<i>Iris chinensis</i>, and of the presence at the base of the flower of an<span class='pagenum'><a name="Page_509" id="Page_509">[Pg 509]</a></span>
+adventitious and imperfect flower-bud, as in the <i>Phlomis</i>, mentioned at
+<a href="#Page_119">p. 119.</a></p>
+
+<p><i>Mon&oelig;cious Misleto</i>, <a href="#Page_193">p. 193.</a>&mdash;In this specimen, exhibited at one of
+the meetings of the Scientific Committee of the Royal Horticultural
+Society in 1869, there were both male and female flowers on the same
+bush. The plant was of the male sex, with numerous long slender
+whip-like, somewhat pendulous, branches bearing comparatively large
+broad yellowish leaves, and fully developed male flowers at the end.
+From the side of one of these male branches, near the base, protruded a
+tuft of short, stiff branches, bearing small, narrow, dark green leaves,
+ripe berries and immature female flowers. There was no evidence of
+grafting or parasitism, of the female branch on the male, the bark and
+the wood being perfectly continuous so that the only tenable supposition
+is that this was a case of dimorphism.</p>
+
+<p><i>Adventitious leaflet and pitcher</i>, <a href="#Page_30">see pp. 30</a> and <a href="#Page_355">355</a>. In a species of
+<i>Picrasma</i>, in which the leaves are impari-pinnate and spread
+horizontally, an adventitious leaflet was observed to project at right
+angles to the plane of the primary leaf. It emerged at a point nearly
+corresponding to that at which the normal pinn&aelig; were given off. The
+appearance presented was thus like that of a whorl of three leaves,
+except that the shining surface of the adventitious leaflet,
+corresponding to the upper face of the normal leaflets, was directed
+towards the axis, <i>i.e.</i>, away from the corresponding portion of the
+neighbouring pinn&aelig;, while the dull surface, corresponding to the lower
+part of an ordinary leaflet, looked towards the apex of the main leaf,
+or away from the axis. In one instance, a stalked pitcher was given off
+from the same point as that from which the supernumerary leaflet
+emerged, the pitcher being apparently formed from the cohesion
+(congenital) of the margins of a leaflet.</p>
+
+<p>In the normal leaf of this plant there is between the bases of the
+pinn&aelig;, a small reddish gland or stipel? attached to, or projecting from,
+the upper surface of the rachis. It appeared from some transitional
+forms that the adventitious leaflet, just mentioned, was due to the
+exaggerated development of this gland, but no clue was afforded as to
+the origin of the ascidium. It was not practicable to examine the
+arrangement of the vascular bundles in the rachis.</p>
+
+<p><i>Additional labella in Phaius.</i>&mdash;A flower of <i>Phaius grandiflorus</i> was
+found in the same condition as the <i>Catasetum</i>, mentioned at <a href="#Page_291">pp. 291</a> and
+<a href="#Page_382">382.</a></p>
+
+<p><i>Tubular stem.</i>&mdash;A species of <i>Sempervivum</i>, exhibited by Mr. Salter, of
+Hammersmith, at one of the summer exhibitions of flowers at the Royal
+Horticultural Society in 1868, under the name of <i>S. Bollei</i>, deserves
+notice from its bearing on the question of such structures as the
+calyx-tubes, the hip of the rose and such like, <a href="#Page_394">see pp. 394</a>, <a href="#Page_482">482</a>. In
+this plant<span class='pagenum'><a name="Page_510" id="Page_510">[Pg 510]</a></span> the leaves appeared to be arranged some on the outside,
+others on the inside, of an erect hollow cylinder, some six inches in
+height. The oldest leaves were outside, the youngest within, so that the
+appearance presented was as if the summit of the axis had been pushed or
+drawn in, much as the finger of a tight glove might be invaginated in
+withdrawing it from the hand.</p>
+
+<p>The plant in question thus furnishes an actual illustration of the
+supposititious case mentioned at <a href="#Page_482">p. 482.</a></p>
+
+<p><i>Double flowers</i>, <a href="#Page_499">see pp. 499</a>, et seq.&mdash;The following species may be
+added to those already recorded: <i>Lychnis coronaria</i>, <i>Hibiscus
+mutabilis</i>, <i>Lotus major</i>, <i>Pisum sativum</i>, <i>Godetia</i> sp., <i>Ipom&oelig;a
+purpurea</i>, <i>Convolvulus minor</i>, <i>Heliotropium peruvianum</i>, <i>Trillium
+grandiflorum</i>, and <i>Phaius grandiflorus</i>.</p>

+<h2><a name="INDEX_OF_NAMES_OF_PLANTS" id="INDEX_OF_NAMES_OF_PLANTS"></a>INDEX OF NAMES OF PLANTS.</h2>
+
+
+<p>[In the following Index the names of the orders that are incidentally
+mentioned are printed in small capitals, those of the genera and species
+in ordinary type. The names are inserted as found in the several
+records, &amp;c., without in general any attempt having been made to
+determine their accuracy. For this reason the authority for the specific
+name is rarely given, such citations being here unnecessary if not
+impracticable. It may, however, be assumed that the names made use of
+are those generally adopted by naturalists.</p>
+
+<p>This index will be found useful for statistical purposes. It will show
+at a glance, at least approximately, how often certain genera and
+species are affected with malformation, as contrasted with others. The
+nature of the malformation may of course be ascertained by referring to
+the particular page indicated by the number. The proportion of wild to
+cultivated plants may also be approximately ascertained, and the effects
+of cultivation estimated. The disproportionate frequency with which some
+species are affected, e.g., <i>Trifolium repens</i>, &amp;c., as contrasted with
+other closely allied, and perhaps equally common species, under
+apparently identical conditions, is also made manifest.]</p>

+
+1.A.  By reading or using any part of this Project Gutenberg-tm
+electronic work, you indicate that you have read, understand, agree to

+(trademark/copyright) agreement.  If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.

+terms of this agreement, you may obtain a refund from the person or
+entity to whom you paid the fee as set forth in paragraph 1.E.8.
+
+1.B.  "Project Gutenberg" is a registered trademark.  It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement.  There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement.  See
+paragraph 1.C below.  There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works.  See paragraph 1.E below.
+
+1.C.  The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works.  Nearly all the individual works in the
+collection are in the public domain in the United States.  If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed.  Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work.  You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D.  The copyright laws of the place where you are located also govern
+what you can do with this work.  Copyright laws in most countries are in
+a constant state of change.  If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work.  The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E.  Unless you have removed all references to Project Gutenberg:
+
+1.E.1.  The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently
+whenever any copy of a Project Gutenberg-tm work (any work on which the
+phrase "Project Gutenberg" appears, or with which the phrase "Project
+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever.  You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2.  If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges.  If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3.  If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder.  Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.
+
+1.E.4.  Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5.  Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6.  You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form.  However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form.  Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.
+
+1.E.7.  Do not charge a fee for access to, viewing, displaying,
+performing, copying or distributing any Project Gutenberg-tm works
+unless you comply with paragraph 1.E.8 or 1.E.9.

+that
+
+- You pay a royalty fee of 20% of the gross profits you derive from
+     the use of Project Gutenberg-tm works calculated using the method
+     you already use to calculate your applicable taxes.  The fee is
+     owed to the owner of the Project Gutenberg-tm trademark, but he
+     has agreed to donate royalties under this paragraph to the
+     Project Gutenberg Literary Archive Foundation.  Royalty payments
+     must be paid within 60 days following each date on which you
+     prepare (or are legally required to prepare) your periodic tax
+     returns.  Royalty payments should be clearly marked as such and
+     sent to the Project Gutenberg Literary Archive Foundation at the
+     address specified in Section 4, "Information about donations to
+     the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+     you in writing (or by e-mail) within 30 days of receipt that s/he
+     does not agree to the terms of the full Project Gutenberg-tm
+     License.  You must require such a user to return or
+     destroy all copies of the works possessed in a physical medium
+     and discontinue all use of and all access to other copies of
+     Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+     money paid for a work or a replacement copy, if a defect in the
+     electronic work is discovered and reported to you within 90 days
+     of receipt of the work.
+
+- You comply with all other terms of this agreement for free
+     distribution of Project Gutenberg-tm works.
+
+1.E.9.  If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from
+both the Project Gutenberg Literary Archive Foundation and Michael
+Hart, the owner of the Project Gutenberg-tm trademark.  Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1.  Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection.  Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2.  LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees.  YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3.  YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3.  LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from.  If you
+received the work on a physical medium, you must return the medium with
+your written explanation.  The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund.  If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund.  If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4.  Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS,' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5.  Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law.  The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6.  INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section  2.  Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers.  It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come.  In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.gutenberg.org/fundraising/pglaf.
+
+
+Section 3.  Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service.  The Foundation's EIN or federal tax identification
+number is 64-6221541.  Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations.  Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org.  Email contact links and up to date contact
+information can be found at the Foundation's web site and official
+page at http://www.gutenberg.org/about/contact
+
+For additional contact information:
+     Dr. Gregory B. Newby
+     Chief Executive and Director
+     gbnewby@pglaf.org
+
+Section 4.  Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment.  Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States.  Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements.  We do not solicit donations in locations
+where we have not received written confirmation of compliance.  To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://www.gutenberg.org/fundraising/pglaf
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States.  U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses.  Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://www.gutenberg.org/fundraising/donate
+
+
+Section 5.  General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone.  For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included.  Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+Each eBook is in a subdirectory of the same number as the eBook's
+eBook number, often in several formats including plain vanilla ASCII,
+compressed (zipped), HTML and others.
+
+Corrected EDITIONS of our eBooks replace the old file and take over
+the old filename and etext number.  The replaced older file is renamed.
+VERSIONS based on separate sources are treated as new eBooks receiving
+new filenames and etext numbers.
+
+Most people start at our Web site which has the main PG search facility:
+
+<a href="http://www.gutenberg.org">http://www.gutenberg.org</a>
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
+
+EBooks posted prior to November 2003, with eBook numbers BELOW #10000,
+are filed in directories based on their release date.  If you want to
+download any of these eBooks directly, rather than using the regular
+search system you may utilize the following addresses and just
+download by the etext year.
+
+<a href="http://www.gutenberg.org/dirs/etext06/">http://www.gutenberg.org/dirs/etext06/</a>
+
+    (Or /etext 05, 04, 03, 02, 01, 00, 99,
+     98, 97, 96, 95, 94, 93, 92, 92, 91 or 90)
+
+EBooks posted since November 2003, with etext numbers OVER #10000, are
+filed in a different way.  The year of a release date is no longer part
+of the directory path.  The path is based on the etext number (which is
+identical to the filename).  The path to the file is made up of single
+digits corresponding to all but the last digit in the filename.  For
+example an eBook of filename 10234 would be found at:
+
+http://www.gutenberg.org/dirs/1/0/2/3/10234
+
+or filename 24689 would be found at:
+http://www.gutenberg.org/dirs/2/4/6/8/24689
