CONTRIBUTIONS TO SOUTH AFRICAN ASCLEPIADOLOaY. 273 



wrongly called in the South African as well as in the European col- 

 lections R. torulosa Dene., from which, however, it is quite distinct. 

 It is very easily recognized by the lax racemose inflorescence, 

 which is much larger than in R. torulosa; the flowers are much 

 narrower in proportion to their length, and the corona is quite 

 distinct. 



It is possible that there are still one or two more species mixed 

 with 7i. torulosa; at present I have not been able to make up 

 my mind about one of them, whether to regard it as a species or 

 merely as a variety. The present species, which is doubtless quite 

 distinct from anything else in the genus, is at present only known 

 to me from the locality given above, but I feel sure that it will be 

 found to occur in many more localities.

Unfortunately the specimens which I got of this species have 

 been boiled so much that it is impossible to get a view of the inner 

 side of the corolla, the corona, and gynostegium. It is distinguished 

 by the long very fleshy leaves, and the rather large flowers, which 

 resemble somewhat those of C. radicans (cf. E^iyl. Bat. Jahrb. vol. 

 xviii. Beibl. 45, p. 12), but are a little smaller, and very likely 

 diflerently coloured.
