HABIT Annual; caespitose; clumped densely. Culms 8–20 cm long. Leaves cauline. Ligule a ciliolate membrane; 0.2–0.3 mm long. Leaf-blades curved; involute; 3–5 cm long; 0.4–0.7 mm wide. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; 3–5 cm long; 1–2 cm wide. Primary panicle branches ascending; 1 -nate; sparsely divided. Panicle branches capillary; flexuous; glabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 1–1.3 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes deciduous; shorter than spikelet. Lower glume elliptic; 0.3–0.5 mm long; 0.3–0.4 length of upper glume; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Upper glume ovate; 0.7–0.8 mm long; 0.6–0.7 length of adjacent fertile lemma; hyaline; without keels; 1 -veined. Upper glume primary vein obscure. Upper glume lateral veins absent.

FLORETS Fertile lemma elliptic, or ovate; 0.8–1.1 mm long; membranous; light brown; without keel; 1 -veined. Lemma apex acute, or acuminate. Palea 0.9–1.2 mm long; 2 -veined. Palea keels approximate.
