Tufted perennial, or sometimes annual; culms 30–250 cm. high.. Leaf-blades 30–60 cm. long, 2–8 mm. wide.. False panicle lax or contracted and fasciculate, 5–80 cm. long; spatheoles linear-lanceolate, 3–5 cm. long, at length reddish and rolled around the peduncle, the latter usually exserted, often by 2 cm. or more; racemes (1.5–)2–2.5 cm. long, (7–)9–14-awned per pair, fulvous to rufous, not deflexed (or very rarely so); raceme-bases unequal, sometimes ± connate, the upper 2–3.5(–4) mm. long, glabrous (very rarely with a few long hairs), the articulation with the peduncle tip glabrous.. Homogamous pairs 1 at the base of the lower, or of both, racemes.. Sessile spikelet (3–)3.5–4.5(–5) mm. long, glabrous to pubescent but typically with a scanty covering of stiff rufous hairs, usually glossy; callus 0.2–0.8 mm. long, short and rounded to cuneate and narrowly truncate; awn 2–3 cm. long, rufously pubescent.. Pedicelled spikelet acute or rarely mucronate.
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.
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.
A grass that grows in dense tufts. It can grow each year from seed or keep growing from year to year. It grows 2.5 m high. The leaf blades are 30-60 cm long by 2-8 mm wide. The spikelets are 4-5 mm long.
Pedicelled spikelets 3–5 mm long, narrowly lanceolate, acute or rarely mucronate at the apex; callus absent; pedicel-tooth up to 0.3 mm long, triangular.
Homogamous spikelets similar to the pedicelled, a single pair at the base of the inferior raceme or both racemes.
Caespitose perennial or sometimes annual; culms up to 250 cm high, erect.
Leaf sheaths glabrous; leaf laminas 30–60 cm × 2–8 mm, rigid.
Perennial or sometimes annual, 0·3–2·4 m. high
