A specimen collected by Gossweiler (no. 3917) in Benguella, has the 
margins of some of the sheaths ciliate and the blades not only packed with 
long coarse hairs above the ligules but hirsute over the greater part of both 
surfaces. Apart from this and the darker colouring of the spikelets it agrees 
with the usual form. Andropogon pachyneurus, Franch. in Bull. Soc. Hist.
