Plants perennial; cespitose, with innovations, without rhizomes, not glandular. Culms 30-85(110) cm, glabrous and shiny below the nodes. Sheaths sparsely hairy at the apices, hairs to 6 mm; ligules 0.1-0.4 mm; blades 10-35 cm long, 2-5 mm wide, flat to involute, glabrous abaxially, scabridulous and sparsely pilose adaxially, hairs to 7 mm. Panicles (25)30-60 cm long, 25-40 cm wide, broadly ovate to obovate, open, diffuse; primary branches 5-25 cm, diverging 20-90° from the rachises, capillary; pulvini hairy or glabrous; pedicels 0.5-25 mm, appressed, only the terminal pedicels on each branch longer than the spikelets. Spikelets 4-18(23) mm long, 1.4-3.4 mm wide, linear-lanceolate, grayish-green or stramineous to purplish, with (4)9-30 florets; disarticulation tardy, basipetal, in the rachillas below the florets, glumes persistent. Glumes narrowly lanceolate, membranous; lower glumes 0.8-2.4 mm; upper glumes 1.5-2.6 mm; lemmas 1.4-2.8 mm, lanceolate, membranous, apices acute to acuminate; paleas 1-2.6 mm, hyaline to membranous, narrower than the lemmas, apices obtuse to acute; anthers 2, 0.3-0.5 mm, purplish or brownish.
