Inflorescence: panicle-like, of simple or compound branches; branches angular, generally ascending to appressed, axis generally glabrous; spikelets generally many, 1--2 per node, generally subsessile, densely packed on branches. Spikelet: ovoid to compressed, falling as one unit, breaking free below glumes, or not at all; florets 2(3), lower floret sterile or staminate, upper florets bisexual, anthers 3; glumes membranous, unequal, lower < upper, short-bristly to hairy, generally green to +- purple, upper glume unawned or shortly awned; lower lemma similar to the upper glume in length and texture, unawned or awned, upper lemma leathery, dorsally rounded, mostly smooth, tip short or elongate, firm or membranous, unawned; upper palea free from lemma at tip, lower palea vestigial to well developed.
