Leaf sheaths glabrous (rarely the inner, protected, ones pubescent); leaf laminas up to 30 cm × 2–5 mm, firm but not rigid, scabrid on the margins and scaberulous on the nerves. False panicle 15–40 cm long, narrow, scanty; spatheoles 2–4 cm long, narrowly lanceolate, glabrous or thinly hirsute, turning reddish-brown; peduncles 1–2.5 cm long, a little over half as long as the spatheole, pilose above with yellowish hairs; racemes 1–2 cm long, 4–7-awned per pair, laterally exserted, deflexed; raceme-bases subequal, the superior 1–1.5 mm long, flattened, stiffly barbate, with an inconspicuous scarious rim. Homogamous spikelets 5–6 mm long, a single pair at the base of the inferior raceme only, villous with white hairs. Sessile spikelets 4.5–5 mm long; callus c. 0.5 mm long, cuneate, narrowly obtuse at the apex; inferior glume oblong-lanceolate, usually dark purple beneath a covering of white hairs; awn 1.5–2.5 cm long, the column puberulous with pallid hairs. Pedicelled spikelets 4–7 mm long, villous with white hairs, terminating in a short awn-point 1–3 mm long; callus scarcely developed; pedicel-tooth obscure. | |
