Sheaths rounded below, distal margins and apices hairy, hairs to 3 mm; ligules 0.2-1.2 mm; blades 5-20 cm long, 3-8 mm wide, flat to loosely involute, glabrous abaxially, scabridulous adaxially, margins scabridulous. Panicles 10-25 (35) cm long, 1-5 cm wide, usually somewhat contracted, sometimes spikelike, often interrupted below; primary branches 0.7-7 cm, appressed or spreading to 30° from the rachis, spikelet-bearing to the base; secondary branches appressed; pedicels 0.2-1.4 mm, appressed. Spikelets 1.6-2 mm, yellowish-green to grayish. Glumes unequal, linear-lanceolate to ovate, membranous; lower glumes 0.5-1.1 mm, usually without veins; upper glumes 1.1-2 mm, subequal to the lemmas; lemmas 1.1-2 mm, ovate, membranous, glabrous (occasionally minutely pubescent), acute; paleas 1-2 mm, ovate, membranous; anthers 2 or 3, 0.5-1 mm, yellowish or purplish. Fruits 0.7-1.1 mm, ellipsoid, laterally flattened, light brownish. 2n = unknown.
