Spikelet: paired, dorsally compressed; sessile spikelet bisexual, glumes > florets, membranous, florets 2, lower vestigial, upper fertile, lemma translucent, tip awned; stalked spikelet staminate or sterile, pedicel hairy; spikelet pair and subtending axis segment breaking as a unit. Fruit: oblong to fusiform.
