Cryton ; 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. 
L C. fimbriata, Wall. Pl. As. Rar. i. 7, t. 8; stems much diffusely 
branched 4-angled to the ends of the branches, corolla rotate, segments 
copiously fimbriate. Wight Contrib. 34; Dalz. & Gibs. Bomb. Fl. 155.

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 ; ollen-masses one in each 
cell, sessile, erect, suborbicular, compressed. Stigma low, conical, 5-angled, tip 
truncate depressed. Follicles slender, straight, terete, smooth. Seeds flat, 
winged, comose.— DrsTRrB. Species 12; Spain, North Africa, Arabia, Western 
a. 
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depend mainly upon published and unpublished drawings and definitions.

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.
