 •crowned with a tuft of hairs. — Perennial herbs with a tuberous rootstock 

 or a fascicle of thick fleshy roots, usually of dwarf habit. Stem simple or 

 much branched, erect, prostrate, or rarely twining, leafy to the top. 

 Leaves opposite. Flowers small or of moderate size, solitary and sub- 

 lateral at the nodes, or two to many together in lateral or terminal umbels 

 or umbel-like cymes. 



Species many, natives of Africa and India. Closely allied to Ceroper/ia, differ- 

 ing ill habit, and in the corolla-tube being saucer-shaped or campanuhtte and not 

 inflated at the base, but Ceropegia loranthijiora tends to connect the two genera. 

 The tubers of most, if not all, ot the species are eaten by the natives.
