Densely tufted perennial, the basal sheaths papery to slightly horny, often strongly flabellate; culms 10–60 cm. high.. Leaf-blades 2–25 cm. long, 2–8 mm. wide, stiff, erect, folded.. Inflorescence of 3–10 (sometimes 2 in depauperate specimens) dense purple racemes each 2–7 cm. long, these subdigitate or borne upon a central axis up to 3 cm. long; internodes and pedicels linear to filiform, 3–5 mm. long, ciliate with white hairs 0.5–1 mm. long.. Sessile spikelet 4.5–8 mm. long, including a callus 0.5 mm. long; lower glume narrowly lanceolate-elliptic, flat or concave on the back, cartilaginous, nerveless or obscurely 2–4(–7)-nerved between the lateral keels, glabrous, wingless, bidenticulate; upper glume awnless or with an awn up to 5 mm. long; upper lemma bilobed for 1/4–1/2 its length, with an awn 4–14 mm. long.. Pedicelled spikelet lanceolate, 5–8 mm. long, glabrous, awnless or with a short awn-point.
Perennial, densely tufted, up to 0.6 m high. Leaf blades 20-250 mm long, 2-8 mm wide. Basal sheaths keeled, flattened. Spikelets (sessile) 4.5-8.0 mm long (pedicellate equalling it or slightly longer), 0.9-1.1 mm wide. Inflorescence with short hairs; racemes 2 or 3 per spathe, 25-60 mm long, pedicels linear, rounded; lower glume of sessile spikelets shallowly concave below.
Sessile spikelet 4.5–6 mm long, pilose at the base; inferior glume with a shallow median groove, glabrous, 1–3-mucronate at the apex; superior glume rounded on the back, usually with an awn 3–4.5 mm long; superior lemma bifid to the middle; awn geniculate, 6–16 mm long; anthers 2.5–3 mm long, straw-coloured.
Racemes 1–5 in terminal subdigitate groups, 3–7 cm long, slender and flexuous, long-exserted from the spatheoles, dark red; peduncles much longer than the racemes; internodes and pedicels filiform, almost glabrous or ciliate on both margins, the internodes shorter than the sessile spikelets.
Leaf sheaths distichous, compressed and ± keeled, glabrous; ligule a very short (c. 1 mm) minutely fringed membrane; laminas 2–17 cm × c. 0.2 mm wide, flat, loosely long-pilose, tapering to a fine point at the apex.
Delicate caespitose perennial; culms 30–50 cm high, erect, unbranched, often reddish; internodes very delicate.
Spikelets similar, 4.5–8 mm long (the pedicelled slightly the longer), glabrous.
Densely tufted perennial 30–45 cm. high.
Pedicelled spikelet male, 5.5–8 mm long.
