Plants perennial; strongly rhizomatous or stoloniferous. Culms 20-65 cm, erect, bases much branched; nodes usually pilose or villous, sometimes glabrous; lower internodes glabrous. Sheaths glabrous, sometimes slightly scabrous; collars pilose at the edges; ligules 1.5-5 mm, often laciniate; blades 2-20 cm long, 2-4 mm wide, involute and curled when dry, sparsely villous behind the ligules, abaxial surfaces scabridulous, adaxial surfaces scabrous. Panicles 2-6 cm; fascicles 6-8 mm. Lateral spikelets with 3 staminate florets; glumes thin, membranous, lanceolate or parallel-sided, not conspicuously fused at the base, apices acute to rounded, often ciliate, veins rarely excurrent; lower glumes dorsally awned, awns exceeding the apices; anthers 3, about 5 mm. Central spikelets with 1 bisexual floret; glumes with excurrent veins forming distinct awns; lemmas exceeding the glumes, ciliate, the midveins sometimes excurrent. 2n = 18, 36.
