Plants annual. Culms 5-40 cm, slender, erect; internodes mostly glabrous, scabridulous or smooth, scabridulous or strigulose below the nodes. Sheaths shorter or longer than the internodes, smooth or scabridulous; ligules 1-2.6 mm, hyaline, truncate to obtuse, sometimes with lateral lobes; blades 0.5-4(10) cm long, 0.8-2 mm wide, flat or involute, scabrous abaxially, shortly pubescent adaxially. Panicles 5-16.2(21) cm long, 1.5-6.5 cm wide, open; primary branches 8-42 mm, often capillary, diverging 25-80° from the rachises; pedicels 2-7 mm, straight or curved, but rarely curved as much as 90°. Spikelets 0.8-1.5 mm. Glumes sparsely strigulose, at least near the apices, 1-veined; lower glumes 0.5-0.8 mm, obtuse to acute; upper glumes 0.6-0.9 mm, broader than the lower glumes, obtuse; lemmas 0.8-1.5 mm, lanceolate, brownish to purplish, glabrous or the midveins and margins appressed-pubescent, apices obtuse to subacute, unawned; paleas 0.8-1.4 mm, shortly pubescent or glabrous; anthers 0.2-0.7 mm, purplish.
