Described from living plants. The type form of this plant (introduced by 
Masson) is identical with the figure in the Botanical Magazine and Jacquin’s figure — 
of Stapelia radiata. Jacquin received this plant from England under the 
erroneous name of S, radiata and evidently had not seen the figure of the true 
D, radiata (Stapelia radiata, Bot. Mag. t. 619) since he quotes no reference to 
that species and also figures the latter as S. replicata. _ 
5. D. modesta (N. E. Br.) ; stems $—1 in. (or more ?) long, J} in. 
thick, ovoid or oblong, with 4-5 obtuse tuberculate-toothed angles, 
_ glabrous ; flowers 2-3 together at the middle of the young _
