Robust perennial arising from a short rhizome clad in hard cataphylls; culms up to 300 cm high, supported by stilt roots, initially decumbent.

False panicle 20–40 cm long, large, lax, decompound; spatheoles 1.4–2.4 cm long, boat-shaped (lanceolate in profile), glabrous, russet-red tinged with yellow and green at maturity; peduncles 3–9 mm long, up to c. 1/3 the length of the spatheole, barbate above with white hairs; racemes 0.8–1.3 cm long, 3–5-awned per pair, projecting laterally from the spatheole, deflexed; raceme-bases subequal, short, the superior c. 1 mm long, flattened, stiffly barbate, with a scarious rim up to 0.4 mm long at the apex. Homogamous spikelets 7–9 mm long, a single pair at the base of the inferior raceme only, glabrous to puberulous on the back, ciliate on the margins. Sessile spikelets 4–5 mm long; callus 0.5–1 mm long, cuneate, narrowly obtuse to subacute at the apex; inferior glume oblong-lanceolate, glabrescent to sparsely and shortly pubescent; awn 1.8–3.2 cm long, the column pubescent with pallid or tawny hairs.
