Description:
Caespitose perennial; culms up to 200 cm high and 1–4 mm in diameter at the base. Leaf sheaths at the base of the plant mostly woolly-tomentose with white hairs, occasionally merely pubescent; leaf laminas up to 45 cm × 2–5 mm, rigid, often coarsely pilose near the base. False panicle 15–45 cm long, lax; spatheoles 3–6 cm long, linear, russet-coloured, eventually inrolled; peduncles usually longer than the spatheoles, pilose above with spreading white hairs; racemes 2–3 cm long, 8–13-awned per pair, with white-pilose internodes and pedicels, terminally exserted on the flexuous peduncle, tardily and imperfectly deflexed; raceme-bases unequal, the superior 2–3 mm long, terete, glabrous or sometimes thinly pilose, the articulation with the peduncle apex marked by a ring of white hairs or these sometimes brown or absent. Homogamous spikelets 5–6 mm long, a single pair at the base of the inferior raceme only. Sessile spikelets 5–6 mm long; callus 0.8–1.2 mm long, linear to narrowly cuneate, acute to very narrowly truncate at the apex; inferior glume narrowly lanceolate, yellowish-green to violet, densely pubescent with fulvous hairs; awn 2–4 cm long, the column fulvously pubescent with hairs 0.2–0.5 mm long. Pedicelled spikelets 4.5–7 mm long, linear-lanceolate, acute and muticous at the apex; callus absent; pedicel-tooth 0.2–0.5 mm long, subulate.
