HABIT Annual; caespitose. Culms 15–50 cm long. Ligule an eciliate membrane; 0.6–0.9 mm long. Leaf-blades flat, or involute; 13–20 cm long; 2–3 mm wide.

INFLORESCENCE Inflorescence a panicle. Peduncle 2–10 cm long.

Panicle spiciform; linear; 5–10 cm long; 0.3–0.5 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; tilted on the pedicel; laterally compressed; gibbous; 1.7–2.1 mm long; falling entire.

GLUMES Glumes reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.7–1 mm long; 0.33–0.5 length of spikelet; hyaline; without keels; 3–5 -veined. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; coriaceous; much thinner above; without keels; 7–9 -veined. Upper glume lateral veins obscure (below), or prominent (above); ribbed. Upper glume apex obtuse.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; ovate; gibbous; 1 length of spikelet; coriaceous; much thinner above; 7 -veined; obscurely veined (below), or prominently veined (above); ribbed; acute. Fertile lemma elliptic; dorsally compressed; 1–1.1 mm long; coriaceous; shiny; without keel. Lemma margins involute. Lemma apex acute. Palea involute; coriaceous.

DISTRIBUTION South America: northern South America, western South America, and Brazil.
