It differs from all the known species in having clavate -hairs on the disc. The flowers, though much smaller than many in the -genus, are very beautiful, and lack the unpleasant smell so -characteristic of stapelias. - -It is not a common species, and as far as our records go has only been -collected in the Tanqua Karroo by Dr. Marloth, and recently the Division -of Botany received specimens from Mr. E. Anderson, Matjesfontein. This -flowered at Pretoria in February 1923, and our Plate was prepared from -these specimens. - -DESCRIPTION:--_Stems_ 4 cm. high, 4-angled, minutely pubescent. -_Rudimentary leaves_ 2 mm. long, deltoid, acute. _Flowers_ 1-3 together -arising about 2/3 up the stem. _Pedicels_ 1·7 cm. long, terete, minutely -pubescent. _Sepals_ 5 mm. long, linear-lanceolate, acute, minutely -pubescent. _Corolla_ 3·6 cm. across when expanded; lobes 1·5 cm. long, -ovate-lanceolate, strongly revolute, so that they appear almost linear, -acute, strongly rugose; tube saucer-shaped, covered with numerous -clavate hairs about 1 mm. long. _Outer corona lobes_ 4·5 mm. long, -3-lobed, concave on the inner face, with the middle lobe narrower and -longer than the side lobes and with the side lobes sometimes bifid or -trifid. _Inner corona lobes_ 5 mm. long, incumbent over the anthers, -2-horned, with the upper horn erect and curving outwards above, and -with the lower horn erect-spreading shorter than the upper horn -(National Herb. 2712). - - * * * * * - -PLATE 121.--Fig. 1, surface view of flower; Fig. 2, median longitudinal -section of flower; Fig. 3, sepal; Fig. 4, petal; Fig. 5, outer corona; -Fig. 6, inner corona and pollen sac; Fig. 7, pollinia. - -F.P.S.A., 1924. - -[Illustration: _122._] - - - - -PLATE 122. - -ANSELLIA GIGANTEA. - -_Transvaal, Natal, Portuguese East Africa._ - -ORCHIDACEAE.

Specimens were sent to England from Natal prior to 1857, and -might be considered, as was suggested by Hooker and the late Dr. Bolus, -a colour variety of the tropical African _Ansellia africana_. Mr. Rolfe -in the _Flora Capensis_ considers it to be a distinct species, as -described by Reichenbach, and we have followed his naming. The figure -given by Bolus (_Ic. Orch. Austro-Afric._ 11. t. 29) represents a colour -form different from that reproduced here. - -The plant is found in the mountainous parts of the eastern Transvaal, on -the coast of Natal, and near Delagoa Bay. Our figure was prepared from a -specimen which flowered at the Division of Botany in June 1922, and -which was collected by Mrs. Sinclair Allen on the Lebombo Mountains in -Swaziland. - -DESCRIPTION:--_Stems_ elongate, terete or somewhat sulcate, 1/3-1 ft. -long, with 6 to many leaves on the upper part or near the apex and -numerous imbricate membranous sheaths below. _Leaves_ distichous, -linear-oblong to elliptic-lanceolate, subacute, ¼-1 ft. long, ½-1½ in. -broad, with 3-5 prominent veins. _Panicle_ terminal, ½-1 ft. long, -usually with several branches, rarely reduced to a simple raceme, with a -few short sheaths below. _Bracts_ triangular-ovate, subacute, 1/6 in. -long. _Pedicels_ slender, 1-1¼ in. long. _Flowers_ medium-sized, light -yellow, more or less barred or blotched with light dusky brown; sepals -and petals spreading, oblong or elliptic-oblong, obtuse, about ¾ in. -long; lip 3-lobed, rather shorter than the sepals; side lobes erect, -oblong, obtuse; front lobe recurved, elliptic-oblong, obtuse or -emarginate; disc with 3 prominent crenulate keels; column clavate, 1/3 -in. long (National Herb.

Cap._ -vol. iv. sect. i. p. 516. - - -It is with pleasure that we figure for the first time this species of -_Pachypodium_, which flowered at the Division of Botany, Pretoria, in -1923, from tubers forwarded by Mr. J. Kirton, Pietersburg, Transvaal. -The genus _Pachypodium_ differs from _Adenium_ (see Plate 16) in having -a pair of spines at the base of the leaves, but the present species -agrees with _Adenium multiflorum_ in its general habit. Both have large -succulent stems, partly below the ground, from which the branches arise. -In _Pachypodium Saundersii_ the pollination mechanism is somewhat -complicated, but in what way the various structures function in this is -not quite clear. The flowers are protandrous and the anthers all -converge to a point. The base of the anther is provided with a pouch and -the filament with a ciliated hood, and these two structures form a cage -for the pollen. The stigma lies within this cage, and the style may -possibly elongate eventually, and thus push the pollen above the -anthers, as in the _Compositae_. The plant flowered freely in Pretoria, -but failed to fruit, and from this it may be assumed that -self-pollination does not take place. - -DESCRIPTION:--_Inflorescence_ arising in an umbellate manner at apex of -stems, up to 11-flowered. _Sepals_ 4 mm. long, 3·5 mm. broad, ovate, -acuminate, acute, glabrous. _Corolla-tube_ 3·5 cm. long, cylindric and -1·2 cm. long below, with a subglobose base, then suddenly dilated and -narrowed towards the apex, glabrous without, pilose within; lobes 2·2 -cm. long, 1·8 cm. broad in the widest part, straight on one side, very -convex and crisped on opposite side, subacuminate, acute. _Filament_ 3 -mm. long, 2 mm. broad, ovate, with a ciliated hood at the base; anthers -6·7 mm. long, linear with a lanceolate, acute appendage 1·5 mm. long, -and a membranous pouch at the base. _Style_ 1·3 cm. long, terete, -glabrous; stigma club-shaped covered with a white opaque jelly-like -substance; ovary 3·5 mm. long, with a cupular disk at the base (National -Herb. 2736). - - * * * * * - -PLATE 123.--Fig. 1, median longitudinal section of the flower; Fig. 2, -stamen; Fig. 3, portion of style with the stigma; Fig. 4, the 2 carpels -with a cupular disk at the base. - -F.P.S.A., 1924. - -[Illustration: _124._] - - - - -PLATE 124. - -ALOE VERECUNDA. - -_Transvaal._ - -LILIACEAE.

Afr._ vol. v. p. 703. - - -This _Aloe_ is another of the many species from the Transvaal described -within recent years by Dr. Pole Evans, and it is here figured for the -first time. Our Plate was prepared from plants collected by Mr. D. J. -Fouche in the Middleburg District, Transvaal, and which subsequently -flowered at the Division of Botany, Pretoria. The specimens on which Dr. -Pole Evans based his description were found by Mr. P. J. Pienaar on the -Wolkberg, near Haenertsberg, in the Northern Transvaal. In the natural -state it usually flowers towards the latter part of December, and the -dark red racemes are then very conspicuous. As soon as winter sets in, -the leaves wither and fall. - -DESCRIPTION:--_Stem_ short. _Leaves_ 8-10, distichous, deciduous, 25-35 -cm. long, 8-10 mm. broad at the base, narrowly linear, distinctly -channelled, rounded at the back, with numerous minute raised white spots -at the base, armed along the edges with delicate white teeth 2-7 mm. -apart. _Peduncle_ stout, 25 cm. long, clothed with broad ovate shortly -cuspidate green empty bracts. _Raceme_ more or less capitate. _Bracts_ -20 mm. long, 15 mm. broad, ovate, acute. _Pedicels_ 25 mm. long. -_Perianth_ peach-red to scarlet, greenish towards the apex, 26-30 mm. -long, 12 mm. in diameter, straight, very markedly 3-angled, contracted -towards the mouth; segments free. _Style_ and _stamens_ not or scarcely -exserted (National Herb. 2743). - -PLATE 124.--Fig. 1, portion of leaf showing white spots; Fig. 2, median -longitudinal section of the flower; Fig. 3, outer perianth-segment; Fig. -4, inner perianth-segment; Fig. 5, anther with part of the filament; -Fig. 6, top of style showing the simple stigma. - -F.P.S.A., 1924. - -[Illustration: _125._] - - - - -PLATE 125. - -GLADIOLUS LUDWIGII var.

Cap._ vol. vi. -p. 150. - -This _Gladiolus_ belongs to the same section of the genus as _G. -Rehmanni_, figured on Plate 20. The variety _calvatus_ has up to the -present only been recorded from the Pretoria and Barberton Districts of -the Transvaal, but the species is a native of Natal, East Griqualand and -the Transkei. The specimens from which our illustration was made were -collected by Dr. I. B. Pole Evans, C.M.G., at Brits, and were found -growing in deep black turf soil. The variety is also figured in the -_Botanical Magazine_, t. 6291, and a comparison of that plate with the -one reproduced here will show a difference in the colouring of the -flowers, but Dr. Pole Evans states that the pale yellow and speckled -forms grow together and are undoubtedly the same. The yellow-flowered -form was introduced into cultivation in England in 1877, and both this -and our plant differ from the species in being glabrous. - -DESCRIPTION:--_Plant_ about 1 m. high. _Old corm_ 4 cm. in diameter, 1·5 -cm. thick, disc-like; new corm more or less globose on the old corm. -_Produced leaves_ about 5, the longest up to almost 1 m. long, the free -portion of uppermost leaf about 30 cm. long; all 0·8-1·8 cm. broad, -strap-shaped, narrowing to the apex, acute or obtuse, equitant at the -base, 12-15-nerved with the main nerves subprominent and with -cartilaginous margins, glabrous. _Inflorescence_ densely many-flowered, -almost 30 cm. long. _Outer spathe valve_ 3·7 cm. long, 2 cm. broad, -ovate, acuminate, acute, 3-keeled below, with membranous margins, -glabrous; inner spathe-valve very similar to the outer, but strongly -2-keeled. _Perianth-tube_ 1·5 cm. long, slightly curved; the upper -perianth-lobe 4·2 cm. long, 1·8 cm. broad, elliptic, shortly apiculate; -two upper lateral lobes 3·5 cm. long, 2 cm. broad, ovate-elliptic, -shortly apiculate at the apex; lowermost lobe 3·2 cm. long, 1·3 cm. -broad, elliptic-ovate, minutely apiculate; two lower lateral lobes 2·5 -cm. long, 6 mm. broad, linear-oblong, apiculate. _Filaments_ 1·2 cm. -long, terete, glabrous; anthers 1·25 cm. long, linear, somewhat -sagittate at the base. _Style_ 2·5 cm. long, terete, glabrous; stigmas 8 -mm. long, linear, broadening to the apex (National Herb. 2731). - - * * * * * - -PLATE 125.--Fig. 1, leaf; Fig. 2, portion of leaf showing ribs; Fig. 3, -median longitudinal section of flower; Fig. 4, inner spathe-valve; Fig. -5, outer spathe-valve; Fig. 6, cross-section of ovary; Fig. 7, style and -stigmas; Fig. 8, stamen. - -F.P.S.A., 1924. - -[Illustration: _126._] - - - - -PLATE 126. - -VELTHEIMIA ROODEAE. - -_Cape Province._ - -LILIACEAE.

Roodeae_, in honour of Mrs. R. Rood of Van -Rhynsdorp, to whom our readers are greatly indebted for so many of the -rare plants we have previously figured. It differs in the shape of the -leaves from any of the species described in the _Flora Capensis_. They -are distinctly undulate. - -_Veltheimia_ is a small genus of 3 species, none of which appears to -have been extensively gathered by recent botanical collectors. The first -known species, _V. viridifolia_, was described by Linneaus (as _Aletris -capensis_) in 1751, and was introduced into European cultivation in -1768, so that a species of the genus was known to botanical science over -150 years ago. - -_V. viridifolia_, Jacq., does quite well under cultivation, but we have -not yet had an opportunity of growing the species here described. - -DESCRIPTION:--Bulb 13 cm. long, 6 cm. in diameter, ellipsoid, covered -with membranous tunics, at the base with a disc-shaped rootstock 6 cm. -in diameter, 2·5 cm. thick, from which the roots arise. _Leaves_ 11 to a -bulb, 12-15 cm. long, 4·5 cm. broad near the base, ovate, acuminate, -acute, clasping at the base, with undulate margins and a broad thick -midrib beneath slightly raised, green and glaucous above, densely -reddish-spotted beneath, glabrous. _Peduncle_ as long as the leaves, 6 -mm. in diameter, terete, reddish by being covered with close-set reddish -spots. _Inflorescence_ 3·5 cm. long. _Bracts_ 1 cm. long, almost -filiform. _Pedicels_ 1·5 mm. long. _Flowers_ somewhat reflexed; -perianth-tube 2·2 cm. long, 4 mm. in diameter, cylindric, faintly -globose and bent about the middle, white with reddish spots; lobes 1·5 -mm. long, 1·5 mm. broad, ovate, obtuse. _Stamens_ fixed to the middle of -the perianth-tube; filaments 1 cm. long; anthers 2·25 mm. long, oblong. -_Ovary_ 1 cm. long, 2·5 mm. in diameter, in the middle spindle-shaped, -furrowed; style 1 cm. long, terete; stigma simple (National Herb. 2739). - - * * * * * - -PLATE 126.--Fig. 1, median longitudinal section of a flower; Fig. 2, -stamen; Fig. 3, pistil; Fig. 4, cross-section through the ovary. - -F.P.S.A., 1924. - -[Illustration: _127._] - - - - -PLATE 127. - -STRUMARIA TRUNCATA. - -_Cape Province._ - - -AMARYLLIDACEAE.

Two of the -species are recorded from Little Namaqualand, but no locality is known -for the other three, nor do any specimens appear to exist in herbaria, -Jacquin’s figures and descriptions being all we know about them. It is -with particular pleasure, therefore, that we reproduce this illustration -of a species of this little-known genus, and our readers are again -indebted to Mrs. E. Rood of Van Rhynsdorp for sending us fresh material. -Our plant differs slightly from Jacquin’s figure, inasmuch as the -dilated portion of the style does not narrow towards the base and is -irregularly lobed above, but on this account we do not feel justified in -keeping it distinct from _Strumaria truncata_. - -_Strumaria truncata_ is a charming little plant with an umbel of white, -sweet-smelling flowers, faintly tinged with pink (the _Flora Capensis_ -states flowers “inodorous”). The bulbs received from Mrs. Rood are being -grown at the Division of Botany, Pretoria, and we feel sure once the -species becomes known it will be sought after by cultivators of our -South African bulbs. - -DESCRIPTION:--_Bulb_ 3 cm. in diameter, globose or ovoid, covered with -pale brown papery tunics, and produced into a distinct neck up to 3·5 -cm. long. _Leaves_ 4-6, arising from a sheath, 2·2-4·5 cm. long, 1·2 cm. -broad, oblanceolate or oblong (strap-shaped), rounded at the apex, -glabrous. _Leaf-sheath_ 1·5-2 cm. in diameter, funnel-shaped, truncate, -fleshy, reddish. _Peduncle_ lateral, 15-23 cm. long, terete, glabrous. -_Spathe-valves_ reddish, 2-3·2 cm. long, longer or shorter than the -pedicels. _Pedicels_ slender, 1·2-2 cm. long, glabrous. _Inflorescence_ -13-25-flowered; flowers white, faintly but sweet-scented. _Segments_ 1 -cm. long, 3·6 mm. broad, lanceolate, obtuse. _Filaments_ connate into a -tube for 5 mm., then free for 7 mm., erect, glabrous; anthers 2·5 mm. -long, oblong, versatile. _Ovary_ 1·5 mm. long, globose, glabrous, with -about 5 ovules in each cell; style dilated, sharply 3-angled below and -united with filaments; free part of style 5·5 mm. long, terete; stigma -minutely 3-fid (National Herb., Pretoria, 2729). - - * * * * * - -PLATE 127.--Fig. 1, median longitudinal section of the flower; Fig. 2, a -perianth segment; Fig. 3, style, showing the dilated 3-angled lower -portion of the 3 stigmas; Fig. 4, a stamen. - -F.P.S.A., 1924. - -[Illustration: _128._] - - - - -PLATE 128. - -MIMETES ARGENTEA. - -_Cape Province._ - - -PROTEACEAE.

In May 1923, Mr. A. T. Prentice collected -specimens near Villiersdorp, very probably in the same locality visited -by Masson. Mr. Prentice writes: “They were found on the slopes of the -south (_i.e._ Villiersdorp) side of French Hoek Peak about 3000 ft. -There were about 50 trees, 3-6 ft. high, and the habit is different from -most of the _Proteaceae_ I have noticed. I do not know how to describe -it, but it is very open and something like a candelabra, branching all -round. The flower spikes all stick straight up, in fact it grows like -the advertised type of pruned apple-tree.” Mr. R. Hallack came across -the species on the Hottentot Holland Mountains, and in June last Mr. T. -P. Stokoe also collected it on the same mountain range. He had noted the -plant two years previously, but was unable to obtain it in flower. It is -from specimens forwarded by Mr. Stokoe that the present Plate was -prepared. - -DESCRIPTION:--_Shrub_ 4 ft. high; branches velvety-tomentose. _Leaves_ -1½-2½ in. long, 1-1½ in. broad, elliptic or oblong-elliptic, with a -subobtuse callus at the apex, entire, slightly narrowed to the base, -indistinctly 9-nerved, very densely tomentose with adpressed silky -hairs. _Heads_ subsessile, 1½ in. long, including the styles, -7-9-flowered, axillary; involucral bracts about 3-seriate, coriaceous, -the outer ovate-oblong, silky tomentose, the inner linear, long-villous; -receptacle densely setose with long weak hairs. _Perianth-tube_ very -short, rusty-villous; segments 1 in. long, linear, rusty-villous; limb -4½ in. long, villous. _Stamens_ 3 in. long; filaments swollen, fused -with the perianth anthers 2¾ in. long, linear; apical gland 1/8 in. -long, ovoid, acute. _Hypogynous scales_ 1¼ in. long, linear, subacute, -white. _Ovary_ ¾ in. long, oblong, pubescent; style 1½ in. long, -filiform, glabrous; stigma 3 in. long, linear, obtuse, furrowed, kneed -at the junction with the style (National Herb. 2728). - - * * * * * - -PLATE 128.--Fig. 1, a single head; Fig. 2, an involucral bract; Fig. 3, -a single flower; Fig. 4, complete perianth segment and a limb showing -position of the stamen; Fig. 5, stigma; Fig. 6, ovary. - -F.P.S.A., 1924. - -[Illustration: _129._] - - - - -PLATE 129. - -POLYXENA ENSIFOLIA. - -_Cape Province._ - - * * * * * - -LILIACEAE.

P., was at first thought to be _P. -pygmaea_, Kunth, but it differs in many respects from the published -figures, and as it agrees quite well with Schönland’s description of _P. -ensifolia_, we have decided to place it under this species for the -present. Dr. Schönland, who saw the living plant at Pretoria, suggested -that it was a species differing both from _P. ensifolia_ and _P. -pygmaea_; but until we know more about the genus both as regards the -variability of the species and its distribution, it seems desirable to -regard it as a form of P. ensifolia. - -_P. ensifolia_ is a pretty little plant. The leaves are semi-erect and -the inflorescence of pale lilac flowers arises between them.

The species is also met with in the Pretoria -District, which is outside its normal range of distribution. In -Basutoland the natives call it “_Mametsana_,” meaning “the mother of the -small water.” The spur contains a watery substance which becomes -jelly-like on exposure to air. - -Around Pretoria the plant flowers in late summer, about February, after -the rains, and is then frequently met with in the veld.

The species is a native of the Barberton District -of the Transvaal, but has not been extensively collected. Mr. Galpin -describes it as “abundant amongst scrub on the hillsides and in the -valleys around Barberton, flowering throughout the year, but chiefly in -June and July.” In cultivation it grows to a rather dense bush 2 to 4 -feet high, and flowers profusely. Very fine specimens are in cultivation -at the National Botanic Gardens, Kirstenbosch, and we are indebted to -the Director of the gardens for the fresh material from which the -accompanying Plate was prepared. The species should prove a great -acquisition to horticulturists. - -DESCRIPTION:--An undershrub, viscid-pubescent erect, 0·4 to 1·2 m. high; -branches alternate or opposite, ascending, leafy, rigid, rather robust, -the lower elongated. _Leaves_ mostly alternate, subfasciculate, -oval-oblong, obtuse or subacute, more or less wedge-shaped at the base, -crenate-serrate, hispid, scabrid, shortly petiolate, 0·6 to 3 cm. long, -3 to 8 mm. broad; lateral veins alternate, narrowly impressed on the -upper face, hispid and raised on the lower. _Flowers_ racemose, -numerous, 2 to 3 cm. long; racemes terminal, simple, subcorymbose and -rather dense at first, afterwards elongating and rather lax, deep -purple, 4 to 30 cm. long; pedicels divaricate or ascending, -glandular-pilose, moderately rigid, 1-flowered, alternate, 6 to 8 mm. -long, the upper crowded; bracts basal, sublinear, solitary or -subfasciculate. _Calyx_ glandular-hispid, deeply 5-lobed, 6 to 8 mm. -long; segments linear-oblong or spathulate or sublinear, obtuse. -_Corolla-tube_ shortly glandular-pubescent, 0·8 to 3 cm. long, -subcylindrical, rather slender, slightly dilated and curved near the -top; limb spreading, 2 to 3 cm. in diameter; lobes obovate-rotund, -entire or retuse, 1 to 1·3 cm. long. _Stamens_ included; style filiform, -glabrous, about 1·5 cm. long; ovary sprinkled especially near the apex -with small glands, otherwise glabrous. _Capsules_ ovoid-oblong, minutely -glandular, 1 cm. long; seeds very numerous, irregularly oblong, 0-5 mm. -long.

That it is distinct enough to be -regarded as a species was very strongly supported by the late Dr. J. -Medley Wood. According to him _A. breviflorus_ grows in swampy ground, -commencing at about 1500 ft. above sea level, and is found upwards to -4000 ft. He observed it occasionally to 4 ft. in height, but the average -was 2 to 3 ft. On the other hand, _A. luteus_ appears on grassy hills -and plains from just above sea level to 2000 ft., but never in swamps. -During the flowering stage it is rarely more than about 1 ft. high, but -afterwards, in fruit, the scape lengthens considerably and often attains -2 ft. in length. These observations by Dr. Wood are confirmed by a -critical examination of the specimens at Kew. The flowers and leaves -appear to be always contemporaneous in _A. breviflorus_, but in _A. -luteus_ the flowers appear first and the leaves are very small.

Mr. -Galpin has recorded the plant from the summit of Saddleback Mountain, at -4500 to 5000 ft., where it occurs as a shrub 8 ft. high. It is somewhat -variable, the corolla differing much in size, and the length and -hairiness of the style fluctuates, perhaps due to sexual differences. -The calyx lobes are either 5 or 6 on the same plant. - -No less than six different names have been applied to this species. Of -these we have, with some reluctance, adopted the oldest, _B. bubalina_, -Sims, using the specific name first applied by the younger Linnaeus in -1781 under the genus _Lonicera_ for specimens collected by Sparmann. A -better known name is _B. capensis_. - -DESCRIPTION:--A small tree reaching 3·6 to 4·2 m. high. _Leaves_ -opposite, petiolate; petioles up to 1·2 cm. long, thick, pubescent; -lamina up to 10·5 cm. long and 5·5 cm. broad, broadly ovate, entire, -rounded or subcordate at the base, with revolute margins and the veins -conspicuous above and very prominent beneath, dark green and glabrous -above, pubescent on all the veins beneath. _Stipules_ semicircular from -a broad base, ending in a linear cusp which almost equals the basal -portion in length and is minutely pilose. _Inflorescence_ terminal, -many-flowered. _Calyx-tube_ 6 mm. long, campanulate; lobes 5 to 6, 1 to -2 cm. long, linear, pubescent. _Corolla-tube_ 2 cm. long, inflated, -puberulous without, glabrous within, with a ring of white hairs near the -base; lobes 5 mm. long, triangular. _Stamens_ 5, inserted on the upper -half of the corolla-tube; filaments very short; anthers with the -connective slightly produced. _Ovary_ inferior, 2-celled, many-ovuled; -style filiform, exserted; stigma clavate. _Fruit_ a subglobose berry, -crowned with the persistent calyx-lobes. - - * * * * * - - PLATE 145.--Fig. 1, calyx; Fig. 2, corolla laid open; Fig. 3, - showing pistil in calyx; Fig. 4, anther; Fig. 5, cross-section of - ovary; Fig. 6, stipule. - - F.P.S.A., 1924. - -[Illustration: _146._] - - - - -PLATE 146. - -PELARGONIUM PULVERULENTUM. - -_Cape Province, Natal._ - - * * * * * - -GERANIACEAE.

The species was first described by Dr. S. Schönland in 1903 -from specimens collected by Miss Alice Pegler near Rustenburg. The -peculiar lax arrangement of the leaves is very characteristic, and Miss -Pegler not inaptly compared its appearance to a loose cabbage. - -In the description accompanying Plate 107 (_Aloe comosa_) we described -the method in which the flowers mature. _Aloe Peglerae_, as far as we -have observed, is an exception to this general rule, as the style is -exserted with the filaments and does not wait until the filaments are -withdrawn, and the perianth withers before protruding. - -Our plate was prepared from specimens which flowered at the Division of -Botany, Pretoria. - -DESCRIPTION:--_Plant_ almost acaulescent with a dense rosette of leaves. -_Leaves_ curved, about 28 cm. long, 5·5 cm. broad, below lanceolate, -ending in a short spine, almost flat on the upper surface, slightly -convex on the lower surface, faintly keeled and spiny on the back in the -uppermost third, with the margins spiny; the spines on lower portion of -leaf about 1 mm. long and about 5 mm. apart, becoming 5 mm. long and 1·5 -cm. apart in the upper part of the leaf. _Peduncle_ solitary from the -middle of the leaf rosette, about 1·2 cm. in diameter and covered with -ovate long-acuminate erect membranous bracts. _Flower spike_ about 18 -cm. long, up to 8 cm. in diameter; flowers at first reddish, becoming -greenish-white at maturity. _Outer perianth-segments_ 2·5 cm. long, 6 -mm. broad, oblanceolate, with the apex slightly recurved, 3-nerved; -inner segments 2 cm. long, 8 mm. broad, oblong, 1-nerved. _Stamens_ at -length long exserted; filaments dark purple above, greenish below, -linear. _Ovary_ 5 mm. long, ellipsoid; style 4·2 cm. long, cylindric, -exserted with the stamens; stigma small (_National Herb.

Both have large -succulent stems, partly below the ground, from which the branches arise. -In <i>Pachypodium Saundersii</i> the pollination mechanism is somewhat -complicated, but in what way the various structures function in this is -not quite clear. The flowers are protandrous and the anthers all -converge to a point. The base of the anther is provided with a pouch and -the filament with a ciliated hood, and these two structures form a cage -for the pollen. The stigma lies within this cage, and the style may -possibly elongate eventually, and thus push the pollen above the -anthers, as in the <i>Compositae</i>. The plant flowered freely in Pretoria, -but failed to fruit, and from this it may be assumed that -self-pollination does not take place.</p> - -<p><span class="smcap">Description</span>:—<i>Inflorescence</i> arising in an umbellate manner at apex of -stems, up to 11-flowered. <i>Sepals</i> 4 mm. long, 3·5 mm. broad, ovate, -acuminate, acute, glabrous. <i>Corolla-tube</i> 3·5 cm. long, cylindric and -1·2 cm. long below, with a subglobose base, then suddenly dilated and -narrowed towards the apex, glabrous without, pilose within; lobes 2·2 -cm. long, 1·8 cm. broad in the widest part, straight on<span class="pagenum"><a id="page_16">{16}</a></span> one side, very -convex and crisped on opposite side, subacuminate, acute. <i>Filament</i> 3 -mm. long, 2 mm. broad, ovate, with a ciliated hood at the base; anthers -6·7 mm. long, linear with a lanceolate, acute appendage 1·5 mm. long, -and a membranous pouch at the base. <i>Style</i> 1·3 cm. long, terete, -glabrous; stigma club-shaped covered with a white opaque jelly-like -substance; ovary 3·5 mm. long, with a cupular disk at the base (National -Herb. 2736).</p> - -<hr> - -<div class="blockquot"><p><span class="smcap">Plate 123.</span>—Fig. 1, median longitudinal section of the flower; Fig. 2, -stamen; Fig. 3, portion of style with the stigma; Fig. 4, the 2 carpels -with a cupular disk at the base.</p> - -</div> - -<hr class="pltt"> -<p><span class="pagenum"><a id="page_17">{17}</a></span>  </p> - -<p><span class="pagenum"><a id="page_18">{18}</a></span>  </p> - -<p><span class="pagenum"><a id="page_19">{19}</a></span></p> - -<div class="figcenter" style="width: 414px;"> -<a href="images/plt_004.jpg"> -<img src="images/plt_004.jpg" width="414" height="550" alt="[Image unavailable.]"></a> - -</div> - -<h2><a id="plt_124"></a><span class="smcap">Plate 124.</span></h2> - -<p class="c"> -ALOE <small>VERECUNDA</small>.<br> -<br> -<i>Transvaal.</i><br> -</p> - -<hr> -<p class="c"> -<span class="smcap">Liliaceae.</span> Tribe <span class="smcap">Aloineae</span>.<br> -<span class="smcap">Aloe</span>, <i>Linn.; Benth. et Hook. f.
