Plants annual. Culms 2-30 cm. Sheaths open to closed; auricles absent; ligules membranous; blades flat or folded. Inflorescences terminal, usually racemes, sometimes reduced panicles, 1-sided, usually exceeded by the leaves. Spikelets laterally compressed, subsessile to pedicellate; pedicels 0.5-1 mm long, 0.5-0.8 mm thick, stout, with 2-7 florets; rachillas glabrous, lowest internodes thicker than those above; disarticulation tardy, not strongly localized. Glumes unequal, shorter than the lowest lemmas, glabrous, with wide hyaline margins, apices obtuse to emarginate, unawned; lower glumes (1)3-5-veined; upper glumes (3)5-9-veined; calluses blunt, glabrous; lemmas membranous, with hyaline margins, indurate at maturity, (5)7-9-veined, veins prominent, apices rounded to emarginate, entire, unawned; paleas shorter than to equaling the lemmas, dorsally compressed; lodicules 2, free, glabrous, entire to lacerate; anthers 3. Caryopses shorter than the lemmas, concealed at maturity, beaked from the persistent style base, falling free; hila round, x = 7.
