Perennials, erect or often geniculate, tussock-forming, stoloniferous (wiry, frequently with adventitious tufts at nodes). Flowering culms 25–70 cm high. Leaves: basal leaf sheath margins glabrous; ligule a fringe of hairs, 0.4–0.5 mm long; blade flat to folded, filiform, 1–6 (–12) cm long, to 2 mm wide, with smooth margins. Inflorescences linear, contracted and spiciform, 3–15 cm long; primary branches solitary, equalling or longer than adjacent internodes, appressed uniformly to axis, spikelet-bearing throughout, with spikelets loosely spaced and fairly even. Spikelets pedicellate, 1.5–2 (–2.5) mm long, evenly distributed in inflorescence; pedicel 0.5–1.5 mm long. Glumes: lower glume linear or lanceolate, c. 2/3 the length of upper glume, 1–1.5 mm long, acute, 1-nerved; upper glume linear, slightly shorter than spikelet, to 2 mm long. Lemma elliptic, 1.5–2 mm long, acute, 1–3-nerved. Palea subequal to lemma, entire. Anthers 3, 0.8–1 mm long. Grain rarely developed, oblong or ovate, subterete, 0.8–1 mm long, 0.4–0.7 mm wide, 0.2–0.4 mm thick, smooth, pale brown. Embryo more than half as long as grain.
Grows inclayey soils of flood plains, muddy flats, waterlogged areas or depressionssubject to submersion in rainy season.
