Tlii's species is exceedingly close to C. nudicaulis, Poiret, and best reccjgnised by 

 the much thicker stem. The spikelets are usually broader and tlie glumes longer ; 

 but in a Senegambian example (referred above to C. nudicaulis), the spikelets are 

 as broad as in the average C. Colymbetes.
