Plants annual; tufted, without innovations. Culms 10-45 cm, erect to decumbent, sometimes with a ring of glandular tissue below the nodes. Sheaths sometimes glandular on the midveins, hairy at the apices, hairs to 4 mm; ligules 0.2-0.5 mm, ciliate; blades 1.5-10 cm long, 1-3(4) mm wide, flat, glabrous or sparsely white-hairy, margins sometimes with crateriform glands. Panicles 4-20 cm long, 2.2-8(10) cm wide, ovate, open to contracted, rachises sometimes with glandular spots or pits below the nodes, rarely with a glandular ring, glands usually dull, greenish-gray to stramineous; primary branches 0.5-6 cm, diverging 20-100° from the rachises; pulvini glabrous or hairy; pedicels 1-4 mm, stiff, straight, divergent, usually with a distal ring of crateriform glands. Spikelets 4-7(11) mm long, 1.1-2.2 mm wide, narrowly ovate, mostly reddish-purple to greenish, occasionally grayish, with 7-12(20) florets; disarticulation acropetal, paleas persistent. Glumes broadly ovate, membranous; lower glumes 0.9-1.4 mm; upper glumes 1.2-1.6 mm; lemmas 1.4-1.8 mm, broadly ovate, membranous, keels occasionally with 1-2 crateriform glands, apices acute to obtuse; paleas 1.3-1.7 mm, hyaline, keels smooth or scabridulous, scabridities to 0.1 mm, apices obtuse to acute; anthers 2, 0.2-0.3 mm, reddish-brown. Caryopses 0.4-0.7 mm, ellipsoid, not grooved, striate, light brown. 2n = 40.
