Spikelet lanceolate, laterally compressed, disarticulating beneath upper floret; glumes very unequal: lower glume acute to mucronate, 3-nerved; upper glume as long as spikelet, acuminate, 5-nerved. Florets 2; lower floret male, rarely sterile or bisexual with lemma membranous, falcate, 3-7-nerved, obtuse, awnless, palea hyaline; upper floret bisexual, lemma similar to firmer in texture than glumes, glabrous, scabrid to scaberulous, 1-7-nerved, minutely 2-lobed at apex, rarely entire, lobes sometimes produced into short hair-like bristles, awned from between lobes, awn geniculate; callus short, hairy; palea 2-keeled.
