Further material may show this to be u distinct species. Of the var. hrunnescens 

 (now excluded) 1 have since seen a piece showing well the rliizome, and describe it 

 below as K. senegalensis.

There is very little to distinguish this species from K. polyphylla, Kuntli, and 

 K, melanosperma, Nees, but the cylindric middle-spike. I have moved all the 

 Angola examples {K. aromaiica, Ridley), which I formerly called K. elatior, into 

 K. polyphylla.
