Caespitose perennial; culms up to 300 cm high, stout, erect. Leaf sheaths glabrous; leaf laminas up to 60 cm × 8 mm, rigid. False panicle 20–60 cm long, copiously branched; spatheoles 2–3.5 cm long, narrowly lanceolate, at length reddish; peduncles half as long to almost as long as the spatheoles, glabrous or pilose above with spreading white hairs; racemes 1–1.5(2) cm long, 6–9-awned per pair, glabrescent to fulvously pilose, embraced by the spatheole, terminally exserted, not or very rarely deflexed; raceme-bases unequal, the superior 1.5–2.5 mm long, terete, usually softly hirtellous, sometimes glabrous, the articulation with the peduncle tip glabrous. Homogamous spikelets similar to the pedicelled, a single pair at the base of the inferior raceme or both racemes. Sessile spikelets 4–5 mm long; callus 0.4–0.8 mm long, cuneate, obtuse; inferior glume lanceolate, yellowish-brown or violet-tinged, the hairs usually fulvous but often pallid and scanty, the back usually glossy; awn (1)2–3 cm long, the column rufously pubescent.
