Tussocky perennial, the basal sheaths becoming fibrous with age; culms 12–60 cm. high, erect.. Leaf-blades filiform, 6–15 cm. long.. Panicle ovate, 1–10 cm. long, the spikelets shortly, usually flexuously, pedicelled in clusters at the tips of the primary branches, these typically bare in the lower two-thirds, glabrous to long-pilose, and ending in a slender bristle.. Spikelets 4–10-flowered, broadly ovate-oblong, 2.5–6 mm. long, dark green with grey hairs, breaking up from the apex, the rhachilla fragile; glumes lanceolate, subequal, 1.5–4.5 mm. long, usually pilose but varying from glabrous to coarsely tuberculate, acute; lemmas ovate-elliptic, 2–3.3 mm. long, pubescent to pilose near the margin and sometimes also on the back, rarely glabrous, broadly obtuse to acute; palea long-ciliate on the keels with tubercle-based hairs 0.7–1.5 mm. long; anthers 3, 0.8–2 mm. long.. Caryopsis narrowly ellipsoid, 1.3 mm. long.
Densely caespitose perennial without rhizomes or stolons; culms up to 70 cm tall, erect, unbranched, glabrous at the nodes, the internodes softly pilose or glabrescent, eglandular; basal leaf sheaths glabrous below (others pilose or glabrescent), firm and strongly ribbed, terete, eglandular, disintegrating into a cushion of persistent fibres; ligule a line of hairs; leaf lamina 5–20(25) cm × 0.5–2(2.5) mm, filiform, densely pilose or glabrous, eglandular, glaucous to bright green.
Panicle 5–7 cm long, ovate, open, the spikelets clustered at the tips of the primary branches (these bare in the lower 2/3) on short flexuous pedicels 1.5–2.5(3) mm long, the primary branches not in whorls, terminating in a slender bristle, glabrous in the axils, eglandular.
Caryopsis 1–1.3 mm long, narrowly elliptic.
