Perennials; clum compressed, stout, tufted, 50-100 cm tall. Blade coriaceous, 30-60 cm long, 5-8
mm wide, often involute farinose; sheath glabrous, marging ciliate; ligule a ring of hairs, ca. 0.5 mm
long. Panicle spike-like, cylindrical, 10-15 cm long, main axis hairy; sterile branches forming bristles
and subtending spikelet, these falling off with spikelet; pedicel 2-3mm long. Spikelets ca. 7 mm long,
lanceolate or broadly lanceolate, acute; glumes more or less hardened; lower glume minute; upper
glume 1/2 as long as spikelet, narrowly oblong, acute; lower lemma and upper lemma equal in length,
acute, broadly lanceolate; upper lemma hyaline.

Perennial forming dense tussocks. Culms stout, 30–120 cm tall, hispid below inflorescence. Leaf sheaths papery, keeled, imbricate at culm base; leaf blades linear, flat or often involute, 10–80 × 0.3–1 cm, base papillose-hispid, apex long acuminate; ligule 0.5–2.5 mm. Inflorescence linear, 5–25 × 1.5–3.5 cm; axis hispid, peduncle stumps short with crateriform tips; involucre usually enclosing one spikelet, rarely 2, basal stipe (1–)2–3 mm; bristles greenish or purple, longest 2–3 cm but not conspicuously longer than the others, all slender, hispid. Spikelet lanceolate, 5–8 mm; lower glume 0.6–3 mm, 0–1-veined, obtuse; upper glume ovate-lanceolate, 1/3–2/3 as long as spikelet, 3–5-veined; lower lemma as long as spikelet, 7–11-veined; upper lemma lanceolate, as long as spikelet, papery, acuminate; anthers usually glabrous, occasionally with 1 or 2 hairs at tip. Fl. and fr. summer and autumn. 2n = 18.
