Plants annual or perennial; tufted, stoloniferous, or rhizomatous. Culms 5-115(160) cm, erect or decumbent, often rooting at the lower nodes, not branching above the base. Sheaths not over¬lapping, open, keeled; auricles absent; ligules membranous, membranous and ciliate, or of hairs; blades flat or involute. Inflorescences terminal, panicles of 2-11, digitately arranged spicate branches; branches with axes 0.8-11 cm long, extending beyond the spikelets, terminating in a point, the spikelets imbricate in 2 rows on the lower sides. Spikelets with 3-7 bisexual florets, additional sterile florets distally; disarticulation usually above the glumes, the florets falling as a unit. Glumes unequal, shorter than the adjacent lemmas, 1-veined, keeled; lower glumes acute, mucronate; upper glumes subapically awned, awns curved; calluses glabrous; lemmas membranous, glabrous, 3-veined (lateral veins sometimes indistinct), strongly keeled, apices entire, mucronate, or awned; paleas glabrous; anthers 3, yellow; ovaries glabrous; styles fused. Fruit utricles; seeds falling free of the hyaline pericarp, transversely rugose or granular, x = 10.
