Culms 30-50 cm, erect, slightly geniculate, with few-to-many tillers. Sheaths ciliate near the throat; blades 8-25 cm long, 3-4 mm wide. Spikes (4.5) 6-10 (13) cm long, 0.5-0.7 cm wide, moniliform, with (4) 6-12 fertile spikelets; rudimentary spikelets usually absent, occasionally 1-2; disarticulation in the rachises, the spikelets falling attached to the internodes above. Spikelets 7-14 mm long, 4-7 mm wide, ovate, pubescent, with 4-7 florets, the distal 2 florets sterile. Glumes 7-10 mm, coriaceous, appressed-velutinous, 2-3-toothed; lemmas of lower spikelets 8-10 mm, toothed, usually awned; lemmas of apical spikelets awned, awns 3-8.5 cm, usually diverging. Caryopses about 7 mm, adhering to the lemmas and paleas. Haplomes DM, DDM. 2n = 28, 42.
