Short-lived perennial forming tough bunches; culms 10–60 cm. high, thin, wiry, ascending.. Leaf-blades narrow, flat or often rolled, 2–10 cm. long, 1–3 mm. wide.. Inflorescence 2–17 cm. long, the clusters ± distant on its wavy main axis, brightly coloured purple and light green; peduncle cuneate, flattened, 1–5 mm. long, ciliate with hooked hairs on the margins, the spikelets paired (sometimes solitary) and side by side on its truncate top.. First spikelet: lower (outer) glume narrowly lanceolate, 2.5–8 mm. long, coriaceous, flattened, ± caudate-acuminate, sharply recurved, the margins ciliate with hooked hairs above; upper glume oblong to narrowly oblong in side view, 3–5.5 mm. long, densely tuberculate and often spinulose, pectinate with hooked spines near one margin, rostrate at the tip; lemma 1.6 mm. long.. Second spikelet (when present): lower (inward) glume narrowly lanceolate, 2.5–4 mm. long, loosely clasping the upper glume, tuberculate-spinulose; upper glume lanceolate in side view, 3–5 mm. long, tuberculate-spinulose, rostrate above with a crest of hooked prickles; lemma 1.5 mm. long..
