HABIT Annual. Culms erect; 10–25 cm long. Culm-internodes smooth; distally glabrous. Lateral branches lacking. Leaf-sheaths longer than adjacent culm internode; glabrous on surface. Ligule an eciliate membrane. Leaf-blades 3–5 cm long; 1–2 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; effuse; 3–15 cm long; 0.25–0.33 of culm length. Primary panicle branches ascending; 3–4 -nate; 2–5 cm long. Panicle branches capillary; smooth; with prominent pulvini.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 0.5–3 mm long; glabrous.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 2–2.6 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; reaching apex of florets. Lower glume lanceolate; 2–2.6 mm long; 1 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2–2.6 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 2–2.3 mm long; chartaceous; without keel; 3 -veined. Lemma surface pubescent; with clavate hairs. Lemma apex erose; obtuse. Palea 2 -veined. Palea surface pubescent; hairy on back; with turgid hairs.
