Caespitose perennial or sometimes annual; culms up to 250 cm high, erect. Leaf sheaths glabrous; leaf laminas 30–60 cm × 2–8 mm, rigid. False panicle 5–80 cm long, lax or contracted and fasciculate; spatheoles 3–5 cm long, linear-lanceolate, at length reddish and rolled about the peduncle; peduncles usually longer than the spatheoles by up to 2 cm or more, rarely shorter, glabrous or pilose above with spreading white hairs; racemes (1.5)2–2.5 cm long, (7)9–14-awned per pair, fulvously to rufously pilose or with the callus and lower part of the internode and pedicel white-hirsute, usually terminally exserted, not or very rarely deflexed; raceme-bases unequal, sometimes ± connate, the superior 2–3.5(4) mm long, terete, glabrous (very rarely with a few long hairs), 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 (3)3.5–4.5(5) mm long; callus 0.2–0.8 mm long, short and round to cuneate and narrowly truncate at the apex; inferior glume lanceolate, yellowish-brown to reddish-brown often tinged with violet, rarely green or glaucous, glabrous to pubescent but typically with a scanty covering of stiff rufous hairs, usually glossy; awn 2–3 cm long, the column rufously pubescent.
