HABIT Perennial; caespitose. Culms geniculately ascending; 10–30 cm long. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 0.5–1.8 mm long; acute. Leaf-blades involute; 5–16 cm long; 2–3 mm wide. Leaf-blade surface smooth, or scaberulous; rough adaxially. Leaf-blade margins scaberulous. Leaf-blade apex abruptly acute, or acute.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 4–8 cm long. Panicle branches smooth, or scaberulous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels smooth, or scaberulous.

FERTILE SPIKELETS Spikelets comprising 2–3 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 4.3–5.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 2.8–3.5 mm long; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 3.5–4 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma ovate; elliptic in profile; 3.5–4.3 mm long; membranous; keeled; 5 -veined. Lemma surface pubescent; hairy below; hairy on back, or on veins. Lemma apex acute. Palea keels ciliolate; adorned above.
