482 LXXXY. ASCLEPIADEZ (BROWN), [ Caralluma. 
diam. outside; lobes about 2} lin. long and the same in breadth at 
the base, more or less spreading, deltoid-ovate, acute, slightly hooked 
at the tips. Outer corona arising from the base of the staminal- 
column, glabrous, cup-shaped, with 5 erect lobes 3-#? lin. long, 
deeply bifid, their subulate segments contiguous at their base, then 
divergent-arcuate; cupular part of the corona reaching to the same 
level as the top of the staminal-column; inner coronal-lobes } lin. long, 
linear, obtuse, incumbent on the backs of the anthers and not or scarcely 
exceeding them, dorsally adnate to the outer corona, glabrous.—K.

Allied to C. robusta, N. E. Br., and to the Arabian C, penicillata, N. E. Br., but 
differing from both in the corona. 
5. C. robusta, V. H. Br. Stems tall, robust, 1-3 in. square, 
acutely 4-angled, glabrous and apparently glaucous; angles toothed ; 
teeth rather small, 1-2 lin. long, deltoid, horizontally spreading. 
Umbels lateral, sessile or on very short (1-3 lin. long) lateral 
shoots, scattered along the upper part of the stems, globose, 20—40- or 
more- flowered, #-1} in. in diam. ; pedicels about 4 lin. long, glabrous. 
Sepals 1-1} lin. long, oblong or oblong-lanceolate, acute. Corolla about 
4 (-5?) lin. in diam., rotate; lobes 14-2? lin. long, 1-1} lin. broad, 
ovate, acute, tuberculate within, with a tuft of long vibratile purple 
hairs at the incurved apex, glabrous outside. Outer corona arising 
about } lin. above the base of the staminal-column and reaching to its 
top, cup-shaped, subtruncate, forming 5 pouches alternating with the 
anthers, sparsely covered with short spreading hairs all over, outside 
and inside; inner coronal-lobes minute, incumbent on the backs of the 
anthers and shorter than them, dorsally adnate to the outer corona, 
and appearing to be 5 minute inflexed teeth of the latter, glabrous.

This is very closely allied to the Arabian C. penicillata, N. E. Br., of which I 
have not seen flowering specimens; but according to the description and figure of 
Detlers it differs in having the pouches of the outer corona truncate and hairy all 
over, inside and out, whilst in C. penicillata they are (according to the figure) pro- 
duced into a blunt tooth on each side of the anther and inflexed inner coronal-lobe, 
and only ciliate on the margin. In a sketch made from the living plant by Schwein- 
furth, the corolla is represented as about 5 lin. in diam., but in the dried state they 
are only about 3 lin., and after boiling in water do not exceed 4 lin. in diam. 
6. C. somalica, V. H. Br. in Kew Bulletin, 1895, 264. Stem 
apparently acutely 4-angled, glabrous; angles slightly toothed. 
Flowers very numerous, in a terminal globose umbel about 2 in. in 
diam. ; pedicels 6-8 lin. long, glabrous. Sepals 14-2 lin. long, lanceo- 
late-attenuate, with a few minute hairs on the back. Corolla 6-7 lin. 
in diam. ; tube short, campanulate, enclosing the corona; limb rotate, 
5-lobed to half-way down ; lobes 24 lin. long, 2 lin. broad, deltoid-ovate, 
acute, quite glabrous outside, with a very minutely velvety surface
