What may be a form of D. scandens, but with prostrate and not twining stems, 
and Smaller, less deeply partite leaves with rounded lobes, is reported from 
Renkwood Station on the White Nile (Brown, 1566). The flowers are not dis- 
tinguishable from those of var, cordofana. 
D. scandens, Lim., is widely spread in America and is there even more variable 
thin in Africa. The typical form is described by Miller as having the stylar 
column pubescent low down ; in our African specimens the stylar column is always 
quite glabrous. In their extreme states the two African varieties ure readily 
distinguishable ; they are, however, connected by intermediate conditions.
