Plants perennial; cespitose, with innovations and short, knotty rhizomes less than 4 mm thick. Culms 30-70(85) cm, erect, glabrous. Sheaths hairy on the margins and at the apices, hairs to 7 mm; ligules 0.1-0.2 mm; blades 10-32 cm long, 3-8 mm wide, flat to involute, both surfaces usually pilose, sometimes glabrous on both surfaces or glabrous abaxially and sparsely pilose adaxially, often with a line of hairs behind the ligules, hairs to 8 mm. Panicles (15)25-45(60) cm long, 15-35 cm wide, broadly ovate to oblong, open, basal portions sometimes included in the uppermost leaf sheaths; primary branches (6)12-20 cm long, diverging 20-90° from the rachises, capillary, naked below; pulvini hairy, hairs to 6 mm; pedicels 1.5-17 mm, divergent or appressed. Spikelets 3-7.5 mm long, 1-2 mm wide, linear-lanceolate, reddish-purple, sometimes olivaceous, with (4)6-12 florets; disarticulation basipetal, glumes persistent. Glumes subequal to equal, (1)1.3-2.3 mm, lanceolate, membranous to chartaceous; lemmas (1)1.3-2.5 mm, ovate to lanceolate, leathery, 3-veined, apices acute; paleas (1)1.2-2.4 mm, membranous, keels sometimes shortly ciliate, apices obtuse to truncate; anthers 3, 0.3-0.5 mm, purplish. Caryopses 0.6-0.8 mm, ellipsoid, strongly flattened, adaxial surfaces with 2 prominent ridges separated by a groove, reddish-brown. 2n = 20, 40, 42.
