HABIT Annual; caespitose. Culms erect; 11–28 cm long; 2 -noded. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1.5–4 mm long; acute. Leaf-blades 0.8–4 cm long; 1–2 mm wide. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; effuse; 2–12 cm long; 0.2–7.5 cm wide. Primary panicle branches 3–17 -nate; whorled at most nodes; 1.2–5 cm long. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 4–23 mm long; glabrous.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.8–2(–2.2) mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate; 1.3–1.5 mm long; 0.8 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong, or ovate; 1.6–1.8 mm long; 0.8–0.9 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute; mucronate.

FLORETS Fertile lemma oblong, or ovate; 1.8–2(–2.2) mm long; membranous, or chartaceous; without keel; 3 -veined. Lemma surface pubescent; with clavate hairs. Lemma apex obtuse. Palea 1 length of lemma; 2 -veined. Palea surface pubescent; hairy on back; with turgid hairs.

FLOWER Anthers 3; 0.6–0.7 mm long.

FRUIT Caryopsis with adherent pericarp; ovoid; 1.3 mm long. Hilum elliptic.
