Hackel l.c., 399, describes 2 vars., breviaristatus and submuticus, based on 
Schweinfurth 2261 and 2191 respectively, which are stated to differ from the 
usual form in having the bristle of the upper glume and the awn of the upper 
floret of the sessile spikelet either reduced ( breviaristatus ) or quite suppressed 
(submuticus). Intermediate conditions, however occur m tne same raceme, 
hence it is hardly necessary to distinguish these forms as varieties, ^hwein- 
furth 2261 was collected at Gir, 111 Bongoland, and 2191 near Ghatta s Seriba 
in Jur ; a var. hirtellus described by Franchet, l.c., and collected near Brazza- 
ville by Thollon and again by Chevalier, appears to be merely a depauperated 
state ; the same applies to Chevalier’s plant from the Upper Oubangui.

Spikelets 2-nate, those of each pair differing in sex and in shape 
(slightly) and structure, one sessile, the other pedicelled (rarely 
solitary and accompanied by an empty pedicel) on the articulate 
fragile rhachis of 1- to many-jomted solitary racemes, terminating 
the culms and their branches ; each raceme supported by a spatheoie 
and forming with it a monostachyum ; monostachya collected into 
a spatheate panicle ; the fertile spikelets falling with the adjacent 
ioint (if any) and the accompanying pedicel ; joints and pedicels 
very finely filiform, with truncate tips. Florets 2, lower reduced 
to an empty valve, upper ^ in the sessile spikelets, $ or neater
