Annual grass from fibrous roots; stems 20-50 (70) cm tall.
Sheaths densely hairy, the hairs long and angled downwards (at least the lower ones); blades 1.5-3 (4) mm wide, flat, usually soft-hairy; ear-shaped lobes lacking at the leaf-bases; ligules hairy, jagged with fine hairs, 0.5-1.5 mm long.
Inflorescence an open, diffuse panicle, 7-15 (rarely 20) cm long, the branches slender, spreading to drooping and usually more or less wavy; spikelets 7- to 12-flowered, slightly compressed, smooth or more or less rough, 2-4 cm long, the stalks mostly longer than the spikelets; florets mostly small, closed, self-fertilizing; lower glumes lanceolate, 3-nerved, (3.5) 4-6 mm long, the upper ones lanceolate, 5-nerved, 5.5-8 mm long; lemmas somewhat leathery, broadly lanceolate, nearly circular in cross-section, tapered, rough, faintly 9-nerved, somewhat compressed, rounded on the backs, 8-10 mm long, up to 4 mm wide, the tips blunt and rounded and merely shallowly notched but readily splitting to the awns, the awns inserted 1-2.5 mm below the tips of the lemmas, usually somewhat twisted and abruptly bent at maturity, broadly spreading, flattened at the bases, 8-12 (15) mm long; paleas 1.5-3 (4) mm shorter than the lemmas; anthers included within the lemmas, about 1 mm long. vol7_3
