Two New West African Ceropegias. 
In 1920 Dr J. M. Dalziel, Medical Officer, Lagos, presented the 
Royal Botanic Garden with tubers of Ceropegia which he believe.} 
to be those of C. Dalzielii, N. E. Br. (Kew Bull. 1913, p. 302). 
When cultivated it was observed at an early stage by Mr L. 
Stewart that there was more than one species concerned, although 
the tubers were much alike. This was confirmed when the 
plants flowered. Both belong to a small group of African Cero- 
pegias which includes C. campanulata, G. Don, and C. Dalzielit, 
N.E. Br. But they are quite distinct from these species and from 
each other. I have had the opportunity of examining the type 
of C. Dalzielii through the kindness of the Director of Kew. 
Both species are more closely allied to C. Dalzielii than to anv 
other of the group. Descriptions of the two are given herewith. 
Ceropegia porphyrotricha, W. W. Sm. Sp. nov.
