Caralluma.] xcv. ASCLEPIADEJ:. (J. D. Hooker.) 77 



4-angled, branches slender and terete above, corolla-tube short funnel-shaped, 

 lobes fringed with long hairs. 



SOUTH DECCAN MTS. ; Nilgherries, Pulneys, &c., Wight, &c. COCHIN, Johnntune. 

 CEYLON ; between Kandy and Badulla. 



Habit of C. adscendens, but differing according to "Wight's plate in the larger 

 flowers with deeply fringed petals. The Ceylon plant, according to a drawing from 

 Thwaites, is smaller with much smaller flowers borne on the 4-angled stems, not on 

 slender terete branches as in the Peninsular one ; it is possibly C. fimbriata. 



1. C. fimbriata, Wall. PL As. Ear. i. 7, t. 8 ; stems much diffusely 

 branched 4-angled to the ends of the branches, corolla rotate, segments 

 copiously fimbriate. Wight Contrib. 34 ; Date. $ Gibs. Bomb. Fl. 155. 



DECCAN PENINSULA ; from the Concan southwards, in arid rocky places. DISTBIB. 

 Ava. 



Wight refers the Peninsular to the Ava plant, remarking that the flowers of the 

 former are much larger (they are 1 in. diam. in Wallich's drawing), but finds no 

 other difference. In both the arms of the coronal lobes are long subulate and hooked. 

 Amongst Wight's drawings is one of a plant with the habit of fimbriata, that is, 

 bearing the flowers on the curved 4-angled ends of the branches, but with short ovate 

 ciliate corolla-lobes, green, banded with purple, ending in fimbriate linear tips. If 

 this is Wight's fimbriata, it differs much from Wallich's. 



53. BOUCEROSIA, Wight $ Arn. 



Fleshy leafless herbs, with thick 4-angled stems, angles toothed. Flowers 

 terminal, rather large, solitary or umbelled, more or less purple. Sepals narrow. 

 Corolla campanulate or rotate ; lobes 5, short, broad, valvate. Corona annular, 

 adnate to the column, 5-lobed ; lobes 2-fid, subulate, erect or spreading with a 

 linear fleshy process on the inner face at the sinus inflexed over the anther. 

 Column minute, short ; anther-tips inappendiculate ; pollen-masses one in each 

 cell, sessile, erect, swborbicular, compressed. Stigma low, conical, 5-angled, tip 

 truncate depressed. Follicles slender, straight, terete, smooth. Seeds flat, 

 winged, comose. DISTRTB. Species 1*2 ; Spain, North Africa, Arabia, Western 

 India. 



For the definition of the species of this genus (as of Caralluma} I have had to 

 depend mainly upon published and unpublished drawings and definitions. 



1. B. umbellata, Wight fy Arn. Contrib. 34; stem very stout, flowers in 

 dense umbels, corolla glabrous. Wight Ic. t. 495 ; Wall. Cat. 8147 ; Dene, in 

 DC. Prodr. viii. 648. Stapelia umbellata, Roxb. Cor. PL iii. t. 241. S. Calla- 

 mulia, Ham. 



DECCAN PENINSULA ; common in arid localities. CEYLON ; rocks near Kornegalle, 

 Thwaites. 



Stem erect or ascending, simple or sparingly branched, 1-2 ft. high, 1-2 in. across 

 the obtuse thick crenate angles. Umbels 2-4 in. diam., globose, dense-fld. Corolla 

 l-l in. diam., streaked closely concentrically with purple. Follicles 4-7 in. long by 

 3- in. diam. Seeds ^ in. long, oblong. 



? VAR. campanulata ; angles of stem thin, corolla smaller without the purple 

 streaks more tubular. B. campanulata, Wight Ic. t. 1287. Wight distinguishes this 

 as above, but Thwaites unites it with umbellata, and in the Herbarium they are in- 

 distinguishable, except by the smaller flower and narrower lobes of the corona ; its 

 native locality is unknown. 



2. B. crenulata, Wight $ Arn. Contrib. 34 ; stems very stout, flowers 

 in dense umbels, corolla with long scattered hairs over the whole inner surface.
