Densely tufted perennial 200-550 mm high; rhizome short, hairy cataphylls present. Leaf blade 20-60 x 1.8-2.2 mm, often rolled. Inflorescence a solitary raceme, 40-180 mm long; rachis triquetrous, broadly winged, undulating, margins scaberulous; pedicel hairy; spikelets paired. Spikelet 2.8-3.2 mm long, hairy, hairs usually overtopping apex; lower glume reduced to small scale up to 0.2 mm long or absent; upper glume shorter than spikelet, 3-nerved, hairy; internode absent; lower lemma as long as spikelet, 5-nerved, densely hairy with white to yellowish hairs 1 mm long; upper lemma as long as spikelet, light brown, exposed; anthers 1.4-1.6 mm long.
Densely tufted perennial; culms 30–100 cm. high.. Leaf-blades filiform or flattened, 4–20 cm. long, 1–3 mm. wide.. Inflorescence a solitary raceme 6–20 cm. long, the spikelets paired on a narrowly winged triquetrous rhachis; pedicels pubescent.. Spikelets narrowly elliptic-oblong, 2.5–4 mm. long; lower glume a tiny membranous scale up to 0.2 mm. long or suppressed; upper glume 2/3–3/4 as long as the spikelet, 3-nerved, pilose, gibbous at the base; lower lemma as long as the spikelet, 5-nerved, pilose with smooth stiff yellowish hairs; fruit ellipsoid, light brown, slightly gibbous and keeled at the base.
Perennial, densely tufted, up to 0.55 m high. Leaf blades 30-60 mm long, 1.8-2.2 mm wide, often rolled. Culm with hairy cataphylls. Spikelets 2.8-3.2 mm long, 1 mm wide. Raceme solitary, 50-180 mm long; spikelets in pairs; upper glume and lower lemma covered with yellow hairs 1 mm long; female-fertile (upper) floret light brown.
