Plants forming hummocks 30–40 cm high. Culms reddish brown; flowering culms c. 1 m high. Leaves: sheath glabrous or outer margin ciliolate; orifice ciliate between auricle and blade; auricles oblong, 0.5–1.5 mm long, glabrous; blade to 25 cm long, 1.2 mm wide, with pseudopetiole c. 5 mm long. Panicles sparse, open, c. 25 cm long; axis prominently ribbed and grooved; branches to 10.5 cm long, filiform, triquetrous or compressed, terminated by a spikelet without obvious pedicel c. 20 mm above penultimate spikelet; pulvini prominent with few stiff hairs. Spikelets broadly lanceolate, terete, 9–13 mm long, 2 mm wide, 7–9-flowered; pedicel slender, 2–12 mm long; rachilla internodes c. 1.2 mm long. Glumes broadly elliptic or oblong, 4–5 mm long, thinly cartilaginous, 1 (–3)-nerved, glabrous; both glumes notched and mucronate from sinus, or lower glume obtuse. Callus blunt, with long dense beard (hairs to 2 mm long). Basal lemma 5–6 mm long (including callus), 5-nerved, hirsute in lower 1/2–3/4; body indurated, margins and lobes thinner; midlobe mucro-like, c. 1.2 mm long; lateral lobes broad, c. 0.6 mm long. Palea lanceolate, about as long as lemma body, notched at apex, membranous, glabrous; keels acute, wingless, scaberulous; flaps very narrow. Anthers c. 3.2 mm long.
