Coarse, caespitose perennial; culms up to 300 cm high, erect. Leaf sheaths glabrous, or pilose towards the summit, rarely pilose throughout; leaf laminas 20–60 cm × 3–10 mm, glabrous or sometimes sparsely hirsute below, usually with long grey hairs at the base. False panicle 20–40 cm long, narrow, usually purplish; spatheoles 2–4.5 cm long, narrowly lanceolate, brownish-red, glabrous, barbate or not at the base; peduncles 0.3–1.5 cm long, glabrous or shortly hirsute above; racemes 1.5–2(2.5) cm long, (3)4–6(9)-awned per pair, deflexed; raceme-bases subequal, the superior 1–2 mm long, flattened, glabrous (except in the fork), truncate at the apex and lacking appendages. Homogamous spikelets 7–9 mm long, 2 pairs at the base of each raceme forming a kind of involucre, scabrid on the margins, muticous. Sessile spikelets 6–8 mm long; callus c. 1.5 mm long, sharply acute; superior lemma of sessile spikelet awned, inferior glume narrowly lanceolate to lanceolate-oblong, glabrous to pubescent; awns 2–5.5 mm long, the column pubescent with white or fulvous hairs 0.2–0.4(0.5) mm long, rarely quite awnless. Pedicelled spikelets 5–7.5 mm long, narrowly lanceolate, muticous or with a terminal bristle up to 5 mm long; callus scarcely developed; pedicel-tooth obscure.
