Plants loosely caespitose. Culms erect or geniculately ascending, 35–170 cm high, 2–5-noded. Leaves: basal sheath margins free almost to base; blade 3–13 cm long, 4–8 (–10) mm wide. Panicles erect or nodding, (1–) 2–6 cm long. Spikelets pedicellate, linear-lanceolate, (6–) 6.8–10 mm long. Glumes about equalling, slightly shorter than or sometimes longer than floret, narrowly lanceolate, long-acuminate to attenuate; margins obscurely ciliolatescaberulous especially towards apex or smooth mainly near base; keel hirsute, with hairs to 1.3 mm long and prominent in upper half; lower glume (6–) 7–10 mm long; upper glume 5.7–9.7 mm long. Callus hairs silky, to c. 1.7 mm long. Lemma lanceolate to narrowly lanceolate or narrowly elliptic, (5–) 6–10 mm long, awned, 5–9-nerved, scaberulous, becoming puberulous or pubescent towards apex; apex bifid with aristulate lobes to c. 2.5 mm long; awn (5–) 8–22 mm long, inserted (1–) 2–3 (–3.5) mm below apex. Palea narrowly lanceolate, with nerves puberulous in upper half. Anthers 2.2–3.2 mm long. Ovary hispid. Caryopsis ellipsoid to obloid.
