This common African plant has been continually mixed with P. JEragrostis ever 

 since Hochstetter issued Schiniper, 760, as Cyperus JEragrostis. The two si)ecie8 

 are evidently allied, very alike in habit and leaves, but se})arated at a glance by the 

 spikelets, which are turgid in P. Eragrostis.
