leaves : the lateral lobes united by pairs into 5 ligulate forked 

 leaflets, alternating with the primary lobes and with the stamens. 



1 C. ADSCE NDEXS (R. Br. 1. c.) branches slender, ascending, 

 bearing each a solitary flower at top ; segments of corolla re- 

 flexed at the edges, acuminated, glabrous. ^ . S. Native of 

 Coromandel. Stapelia adscendens, Roxb. cor. 1. p. 82. t. 30. 

 Corollas size of those of Periploca Grceca, yellowish ; seg- 

 ments tipped with violet. Stems rooting at the base. Flowers 

 variegated with purple and yellow, ex Roxb., usually drooping. 



Attending Caralluma. Fl. July. Clt. 1804. Sh. 1 to 2 ft. 



2 C. FIMBRIA'TA (Wall. pi. 

 asiat. rar. 1. p. 7. t. 8.) branches 

 elongated, attenuated ; flowers 

 axillary, solitary, subcampanu- 

 late, drooping ; segments of co- 

 rolla falcate at top (f. 15. e.), 

 with replicate, fringed edges, 

 fj . S. Native of the Burmese 

 empire, on sterile sandy hills at 

 Yenangeum, on the banks of the 

 Irrawaddy ; and among the ruins 

 of Pagamon. Stem branched 

 at top. Segments of corolla 

 naked in the lower part, marked 

 with many transverse purple 

 lines, pale yellow beneath ; up- 

 per part purple ; upper mar-in 



straight and downy, fringed behind with articulated vacillating 



hairs. Very closely allied to C. adscendens, but that species 



iffers from this in the absence of the long vacillating hairs to 



s corolla. Stapelia subulata, Forsk. cat. arab. p. 108. no. 

 193. t. 7. is the same, or a very nearly allied species, (f. 15.)

X\ . BOLCERO'SIA (from j3oupc, boukeros, furnished 

 with buflalos' horns ; in reference to the curved lobes of the 

 corona). Wight and Arnott, contrib. ind. bot. p. 34. Caralluma 

 species, Haw. and Wall. Stapelia species, Roxb. 



Lix. SYST. Pentdndria, Digynia. Corolla subcampanulate, 

 5-cleft ; segments broadly triangular, with acute recesses. 

 Column of fructification hardly exserted. Stamineous corona 

 15-lobed; lobes disposed in a double series ; the 5 inner ones 

 opposite the stamens, and lying upon the anthers ; the rest ex- 

 tenor, erect, or a little incurved at apex, adhering to the back 

 of the inner ones. Anthers simple at the apex ; pollen masses 

 erect, tetragonal, pellucid on the one side at the margin, 

 stigma mutic. Follicles smooth, terete, attenuated at the apex. 

 Seeds comose. Fleshy, leafless, erect plants, with the habit of 

 Slapelta. Branches and stems tetragonal ; with toothed angles. 

 Flowers numerous, terminal, umbellate. In Carallvma the 

 lateral lobes of each leaflet of the corona are separated by 

 means of the middle or primary lobe, with the edge of which 

 they cohere at the base : in this genus, on the contrary, the 

 edges of the lateral lobes of each leaflet cohere, and their 

 line of junction is also attached along the middle of the back 

 of the primary lobe. In both genera the lateral lobes cohere 

 by the margins with the lateral ones of the adjoining leaflet ; 

 so that in Caralluma we have a corona of 10 narrow and 5* 

 broad segments, attached to each other by the edges only, and 

 forming consequently a simple series, while, in Boucerotm the 

 broad segments are surrounded by the 10 narrow ones, and 

 a double corona is formed. Wight, and Arnott, contrib. ind 

 bot. p. 34. 



1 B. UMBELLA TA (Wight and Arnott, 1. c.) segments of co- 

 rolla glabrous. I? . S. Native of the southern provinces of

the Indian peninsula, in arid places. Caralluma umbellata, 

 Haw. syn p. 47. Wall. ascl. no. 20-21. Stapelia umbel- 

 lata, Roxb. cor. 3. t. 24 1 . Stapelia Callamulia, Haw. Flowers

2 B cRENn-A'TA (Wight and Arnott, 1. c.) segm'ents of co- 

 rolla fringed on the edges. fj. S. Native of the Burmese 

 empire, on sandy mountains, near the town of Se^aen, on the 

 left bank of the Irrawaddy, opposite Ava. CaraHuma crenu- 

 late, Wall. pi. asiat. 1. p. 6. t. 7. Corollas pale greenish-white 



low, yellow above, and ornamented with broadish transverse 

 stripes, which become narrower as they approach the base. 

 This is a smaller, more compact, and more glossy plant than 

 the preceding. 



Crenulated Boucerosia. Clt. 1829. Shrub | foot.

XVI. HUTCHI'NIA (named after Mr. Hutchin of Norwich, 

 a most successful cultivator and liberal distributor of succulent 

 plants). Wight and Arnott, contrib. ind. bot. p. 34. 



LIN. SYST. Pentdndria, Digynia. Corolla subcampanulate, 

 5-cleft. Column of fructification hardly exserted. Stamineous 

 corona 20-lobed ; the 5 inner lobes lying on the anthers, the 

 next 5 outside of these alternating with them, each of these 5 

 furnished with 2 lateral lobes, which exceed the middle one. 

 Anthers simple at top. Pollen masses erect, pellucid on the 

 margin on one side. A fleshy, leafless, erect plant ; branches 

 tetragonal : with toothed angles. Flowers numerous, terminal, 

 subumbellate. Corolla pilose inside. 



1 H. I'XDICA (Wight and Arnott, contrib. ind. bot. p. 35.). 



^ . S. Native of the peninsula of India, in arid places Wi<rht 



cat. no. 1520. Teeth of branches reflexed. Flowers pile,' 



greenish white outwardly, but tinged with purple, and covered 



with purplish hairs within. Follicles not seen.

XVII. ERIOPE'TALUM (from t?a > v , erion, wool, and 

 TfraXov, petalon, a petal ; segments of corolla usually densely 

 villous inside). Wight, contrib. ind. bot. p. 35. 



Lix. SYST. Pentdndria, Digynia. Corolla subcampanulate. 

 5-cleft ; segments narrow, linear : with broad recesses. Sta- 

 mineous corona 15-lobed; the 5 inner lobes lying upon the 

 anthers; the 10 exterior ones erect, approximate, adhering to 

 the inner series. Anthers simple at apex ; pollen masses fixed 

 nigh the base, erect, lying upon the stigma, pellucid on the 

 margin on one side. Follicles slender, glabrous. Erect, 

 rather branched herbs. Stems terete. Leaves minute, scale- 

 formed, adpressed. Flowers small, umbellate ; umbels lateral 

 or terminal, sessile. Segments of corolla longer than the tube, 

 usually clothed with dense villi or wool inside, hence the generic 

 name. This genus agrees in habit with Microttemma, but differs 

 in the form of the corona; on the other hand it resembles 

 Boucerosia in the corona, but has a widely different habit. 



1 E. PARVIFLORUM (Wight, I. c.) segments of corolla hardly 

 longer than the tube, woolly ; corona exceeding the gynoste- 

 gium or column of fructification. % . S. Native of Dooneie

Small-Jloicered Eriopetalum. PI. erect. 



2 E. ATTENUA'TUM (Wight, 1. c.) segments of corolla slender, 

 attenuated, villous, twice or thrice longer than the tube ; corona 

 shorter than the gynostegium. 7/. S. Native of Doongie 

 Royle. 



Altenualed-petaQed Eriopetalum. PI. erect. 



5 E. LEVIGA TUM (Wight, 1. c.) segments of corolla linear, 

 with undulated margins, nearly glabrous, almost twice as long 

 as the tube ; corona equal in length to the gynostegium. T( . S.
