Densely tufted perennial, 0.16-1.00 m high; basal sheaths distichous, keeled, flattened; culms much branched above, slender, reddish throughout. Leaf blade 50-280 x 1.8-4.0 mm; ligule a minutely fimbriate membrane. Inflorescence a glabrous, solitary raceme, in fascicles of 1-6; pedicels linear, short, rounded, glabrous; internodes ± 1/5 length of sessile spikelet; spikelets paired: one sessile, the other pedicelled. Sessile spikelet 4.0-4.5 mm long, awnless; lower glume flat on back; upper glume boatshaped, sharply keeled. Florets 2; lower floret reduced to a lemma; upper floret bisexual. Pedicellate spikelet larger, 4.0-5.3 mm long, male. Flowering time July-Jan.
Racemes solitary, gathered into fascicles of 1–6 at regular intervals along the culm, 3–4 cm long, slender, flexuous, virtually glabrous, short-or long-exserted from the spatheoles, dark red; peduncles about as long as the racemes; internodes and pedicels filiform, very short, glabrous, the internodes c. 1/5 the length of the sessile spikelets.
Leaves glabrous; basal sheaths distichous, laterally compressed and keeled; ligule a very short (c. 0.5 mm) minutely fringed membrane; laminas 5–28 cm × 1.8–4 mm wide, keeled, tapering to a very fine point at the apex.
Delicate caespitose perennial; culms up to 140 cm high, erect, much-branched above, reddish throughout.
Sessile spikelet with a small crown of hairs at the base; anthers 2–2.3 mm long, straw-coloured.
Spikelets similar, 4–5.3 mm long, awnless; inferior glumes flat on the back.
