Plants rhizomatous, often with widely spaced single culms and only a few vegetative shoots, varying to loosely cespitose. Culms (20) 25-70 (100) cm. Sheaths tightly enclosing the culms; vegetative shoot blades 0.5-1.5 mm in diameter, conduplicate, deep green, abaxial surfaces smooth to slightly scabrous, adaxial surfaces scabrous on the ribs; cauline blades conduplicate or flat; abaxial sclerenchyma in narrow strands; adaxial sclerenchyma absent. Inflorescences 5-8 cm, closed or open. Spikelets 8-11 mm, with 4-7 florets. Lower glumes 2-3 mm; upper glumes 4-5 mm, acute to acuminate; lemmas 5-6 mm, pale green with violet borders, smooth or scabrous near the apices, apices awned, awns 1-2.5 (4) mm; anthers 2-2.6 mm. 2n = unknown.
