What may be a form of D. scandens, but with ].rostrate and not twining stems, 

 and smaller, less deeply partite leaves with rounded lobe?, is reported from 

 Benkwood Station on the White Nile {Broun, 1566). The flowers arc not dis- 

 tinguishable from those of var. cordofana. 



D. scande7is, Linn., is widely spread in America and is there even more variable 

 than in Africa. The typical form is described by MuUer as having the stylar 

 column pubescent low down; in our African speciniens the stylar column is always 

 quite glabrous. In their extreme states the two African varieties are readily 

 distinguishable ; they are, however, connected by intermediate conditions.
