'I'lie variHtion in tlie leaves in this species is very ^reat; in Quartin-Dillon & 

 Petit, 13, the upper leaves are ovate, sessile, and rounded at the base, the lower 

 lanceolate ; while the lowest has a quasi-petiole | in. long. 



Var. loandensis, C. B. Clarke. Leaves (even the upper ones) narrowed at the base 

 into a short quasi-petiole.— C. latifolia, Rendle in Cat. Afr. PI. Welw. ii. 77, partly.

This is near C. hoissieriana, but differs from that (as from C. Schinzii) by its 

 much narrower spathes.
