Spikelets 2-nate, those of each pair differing in sex and more 
or less in shape, or those of the lowest pair or pairs homogamous 
(3 or neuter), one sessile, the other pedicelled, on the articulate 
fragile rhachis of few- to many-jointed paired racemes, termi- 
nating the culms and their branches ; raceme-pairs supported by 
a spatheole, collected into scanty or compound to decompound 
spatheate panicles ; the fertile spikelets falling with the con- 
tiguous joint and the accompanying pedicel ; joints and pedicel 
finely filiform with more or less obliquely truncate sometimes 
obscurely auricled tips, in. racemes with homogamous spikelets the 
joint or joints below the lowest fertile spikelet entering into the 
formation of the raceme-base, shorter to very short, eciliate and 
tardily disarticulating. Florets 2, lower reduced to an empty valve, 
upper & in the sessile spikelets of the heterogamous pairs, $ or 
neuter (rarely quite suppressed) in those of the homogamous pairs 
and in the pedicelled spikelets. Fertile spikelets more or less 
flattened dorsally, but with rotfnded sides, awned, very rarely 
awnless (6, H. exdrmata ) ; callus short and obtuse or more often 
acute to pungent, shortly bearded. Glumes equal, more or less 
charfcaceous, mostly thin, the lower narrowly truncate or 2-dentate, 
sometimes with a very shallow longitudinal depression, with very 
narrow involute margins up to two-thirds or more, then equally 
narrowly indexed from the very fine short or obscure keels, the 
upper narrowly and shallowly boat-shaped, rounded on the back 
below, finely keeled towards the tips only, 3 -nerved. Valves ciliate
