HABIT Annual. Culms erect, or geniculately ascending; 20–100 cm long. Ligule a fringe of hairs. Leaf-blades 2–30 cm long; 2–4 mm wide.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 3–10; borne along a central axis; unilateral; 2–10 cm long. Central inflorescence axis 4–20 cm long. Rhachis angular; puberulous on surface. Spikelet packing regular; 2 -rowed.

Spikelets in pairs. Fertile spikelets pedicelled. Pedicels free, or fused to each other; united below; oblong; glabrous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; cuspidate, or acuminate; (2.5–)3–4 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.

GLUMES Glumes one the lower absent or obscure; exceeding apex of florets; thinner than fertile lemma. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface pubescent. Upper glume apex acute, or acuminate; muticous.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 0.9 length of spikelet; 5 -veined; pubescent; acute, or acuminate; muticous. Fertile lemma elliptic; 2 mm long; indurate; without keel. Lemma surface granulose. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 0.3–0.5 mm long overall. Palea involute; indurate.

DISTRIBUTION Africa: northeast tropical, east tropical, southern tropical, middle Atlantic ocean, and western Indian ocean. Asia-temperate: China and eastern Asia. Asia-tropical: India, Indo-China, Malesia, and Papuasia. Australasia: Australia. Pacific: southwestern, northwestern, and north-central.
