Basal leaf sheaths silky pubescent at the base, otherwise the sheaths glabrous; leaf laminas up to 80 cm × 3–7 mm, glabrous, stiff and harsh, scabrid on the margins and scaberulous on the nerves, strongly glaucous, rarely soft and green. False panicle 30–60 cm long, linear-oblong, lax; spatheoles 2.6–4 cm long, narrowly lanceolate, glabrous or sparsely pilose, turning glaucous brown; peduncles 2–3 cm long, 1/2–3/4 as long as the spatheole, pilose above with white hairs; racemes c. 1.5 cm long, 5–8-awned per pair, exserted laterally on the curved peduncles, tardily deflexed; raceme-bases subequal, the superior up to 1 mm long, flattened, stiffly barbate, the apex produced into a lobed scarious rim 0.2–0.5 mm long. Homogamous spikelets 8–9 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, subacute at the apex; inferior glume oblong-lanceolate, villous with white hairs, becoming dark purplish-grey at maturity; awn 16–25 mm long, the column shortly pubescent with tawny hairs.
