Spikelets 2-nate, those of each pair differing in sex and (in the 
African species) also much in shape, one sessile, the other pedicelled 
on the articulate fragile rhachis of solitary spike-like racemes, the 
pedicelled tardily separating from their pedicels, the sessile deciduous 
together with the adjacent joint of the rhachis and the pedicel. 
Florets 2 ; lower upper $ in the sessile, £ or neuter in the pedicelled 
spikelets. Sessile spikelets : Glumes equal or subequal ; lower deeply 
grooved (in the African species), rarely flat, 2-dentate or 2-mucronate, 
more or less chartaceous, upwards acutely 2-keeled with indexed 
margins, keels winged ; upper glume boat-shaped, keeled upwards 
with a bristle-like awn. Valves hyaline, of lower floret entire, 
muticous, of upper 2-fid and awned from the sinus. Valvules more or 
less equalling their valves, hyaline. Lodicules 2, cuneate. Stamens 
3. Stigmas linear-oblong, laterally exserted. Grain oblong, obtusely 
trigonous ; embryo reaching to the middle of the grain. Pedicelled 
spikelets flat, with (in the African species) a strongly nerved or ribbed 
lower glume, and 2 florets resembling the lower floret of the sessile
