Plants cespitose, shortly rhizomatous. Culms to 60 cm, glabrous, hairy below the spikes, nodes shortly hairy. Sheaths smooth, glabrous; auricles absent or to 0.5 mm; ligules 0.2-0.8 mm, truncate; blades 3-4 mm wide, adaxial surfaces densely strigulose over the veins, all veins equally prominent. Inflorescences spikes, 9-17 cm long, 8-10 mm wide, erect, with solitary, sessile or subsessile spikelets. Spikelets 15-20 mm, with 4-6 florets. Glumes 9-11 mm long, 1.5-3 mm wide, with 4-5 veins, hairy, acute, unawned; lemmas 10-12 mm, hairy, unawned or awned, awns to about 1 mm; paleas with short and long hairs on the keels; anthers 3-4 mm.
