6-10 lin. long, with a short white stipe, the remainder divided about

longer than the sessile, oblong, barren. Glumes equal, greenish 
tinged with red or more or less suffused with purple ; the lower 2-

Spikelets 2-nate, of each pair differing in sex and mostly also more 
or less in shape and size, one sessile, the other pedicelled, on the 
articulate fragile rhachis of many-jointed solitary racemes termi- 
nating the culms and their branches, supported by spathes and fre- 
quently collected into a false panicle, the sessile spikelets falling with 
the contiguous joint and the accompanying pedicelled spikelet ; 
joints and pedicels thickened upwards, often rather stout with a 
scarious cupuliform and more or less dentate terminal append- 
age. Florets 2, lower reduced to an empty valve, upper $ in the 
sessile, $ , neuter or 0 in the pedicelled spikelets or both suppressed 
in these. Sessile spikelets dorsally compressed or sometimes in 
their low~er half almost terete, awned ; callus short with a short 
beard at the very base. Glumes equal or subequal, lower char- 
taceous (often thinly) to subcoriaceous, more or less convex ^to sub- 
semiterete) or flat on the back with, at least from the middle upwards,
