Plants perennial; cespitose, with innovations and short, knotty rhizomes less than 4 mm thick. Culms 20-65 cm, erect, viscid. Sheaths usually viscid, hairy at the apices and on the collars and margins, hairs to 6 mm; ligules 0.1-0.3 mm; blades 5-18 cm long, 2-4 (5) mm wide, flat to involute, sometimes viscid, densely hairy behind the ligules, hairs to 8 mm. Panicles 18-35 cm long, 10-30 cm wide, broadly ovate, open; primary branches 3-18 cm, diverging 10-90° from the rachises, stiff, viscid, naked basally; pulvini hairy, hairs to 6 mm; pedicels 0.2-1.2 mm, appressed. Spikelets 3.5-6 (7.6) mm long, 1-1.5 mm wide, linear-lanceolate, stramineous to reddish-purple, with 4-10 florets; disarticulation basipetal, glumes persistent. Glumes lanceolate, membranous; lower glumes 0.9-1.8 mm; upper glumes 1.2-2 mm, 1-3-veined; lemmas 1.5-2.2 mm, ovate to lanceolate, membranous, 3-veined, lateral-veins evident, apices acute; paleas 1.2-2 mm, hyaline, not wider than the lemmas, apices obtuse; anthers 3, 0.2-0.4 mm, purplish.
