Plants forming compact symmetrical hummocks 0.1–0.2 m high, to 1 m wide, stoloniferous, with stout brown aerial roots, not resinous. Flowering culms 0.4–0.5 m high, densely fastigiate. Leaves: sheath with many ribbed nerves, glabrous; orifice pubescent; blade spreading or recurved, folded, 2–7 (–10) cm long, 0.7 mm wide. Panicles spike-like, 7–15 cm long, to 1 cm wide; axis semiterete to flat or triquetrous; branches to 1.5 cm long. Spikelets lanceolate, terete to compressed, c. 9 mm long excluding awns, closely 3-or 4-flowered; pedicel 0.5–8 mm long; rachilla ±terete with internodes c. 1.3 mm long. Glumes ±equal, lanceolate, 7–9 mm long, scarious to thinly cartilaginous, 3 (–5)-nerved, glabrous. Callus c. 0.6 mm long, blunt, bearded. Basal lemma: body ±4 mm long including callus, indurated, with longitudinal rows of spreading hairs, shiny; lobes flat to folded; midlobe often slightly longer than laterals; lobes and awns recurved and spirally twisted, 2–8 mm long. Palea c. 4.5 mm long, acuminate, entire, cartilaginous at base, gradually thinner towards apex, glabrous; keels shorter than body, wingless; flaps very narrow. Anthers 1.8–2 mm long.
