Description:
Caespitose perennial arising from short rhizomes; culms up to 60 cm high (up to 1 m in exceptionally robust specimens), wiry, standing above a dense leafy tussock 10–20 cm high. Leaf sheaths compressed and keeled, glabrous or rarely obscurely puberulous; leaf laminas 2–15(30) cm × 1–2(4) mm, narrowly linear to conduplicate and filiform, flexuous, glaucous, harshly scaberulous. False panicle up to 30 cm long, typically scanty with only 2–10 raceme-pairs but sometimes a little fuller with more raceme-pairs; spatheoles 3–8 cm long, linear-lanceolate, at length reddish; peduncles about as long as the spatheoles, glabrous or with white bulbous-based hairs above; racemes 2–4 cm long, 8–13(16)-awned per pair, white-villous, terminally exserted, never deflexed; raceme-bases unequal, the superior 2.5–5 mm long, filiform, glabrous or more usually pubescent to hirsute, with or without a white beard at the foot. Homogamous spikelets similar to the pedicelled, a single pair at the base of the inferior or both racemes. Sessile spikelets 4–6.5 mm long; callus 0.5–1.5 mm long, subacute to acute; inferior glume linear-elliptic, yellowish-green to violet, white-villous but occasionally the hairs rather sparse; awn 10–35 mm long, puberulous with white hairs 0.1–0.3 mm long. Pedicelled spikelets 3–7 mm long, narrowly lanceolate, white-villous, acute and muticous at the apex; callus absent; pedicel-tooth 0.2–1 mm long, subulate.
