HABIT Perennial; culms solitary. Rhizomes short. Butt sheaths herbaceous; glabrous. Culms 10–30 cm long. Ligule an eciliate membrane; 0.3–0.7 mm long. Leaf-blades 5–6 cm long; 1.5–4 mm wide. Leaf-blade surface smooth to scabrous; rough adaxially.

INFLORESCENCE Inflorescence a panicle; subtended by an inflated leaf-sheath; embraced at base by subtending leaf.

Panicle spiciform; elliptic; 0.9–1.8 cm long; 0.6–1.1 cm wide. Panicle axis with rounded ribs. Panicle branches pubescent.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 3.5–5 mm long; falling entire.

GLUMES Glumes connate along margins below; 0.75 of their length connate; similar; exceeding apex of florets. Lower glume oblong; 3.5–5 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein ciliate. Lower glume surface pubescent. Lower glume apex acute; awned; 1 -awned. Lower glume awn 0.7–1.5 mm long. Upper glume oblong; 3.5–5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein ciliate. Upper glume surface pubescent. Upper glume apex acute; awned; 1 -awned. Upper glume awn 0.7–1.5 mm long.

FLORETS Fertile lemma ovate; 2–3 mm long; membranous; keeled; 5 -veined. Lemma margins ciliolate; hairy above. Lemma apex obtuse; awned; 1 -awned. Principal lemma awn dorsal; arising 0.25–0.33 way up back of lemma; curved; 3.5–6 mm long overall; clearly exserted from spikelet. Palea 1–1.5 mm long; 0.5 length of lemma.

FLOWER Lodicules absent. Anthers 3; 1.3–2 mm long. Stigmas protogynous; terminally exserted; pubescent. Ovary glabrous.
