Tufted to trailing short-lived perennial or annual 200-900 mm high; rhizome slender; prostrate at base; leaves mostly cauline; culm weak, rooting at lower nodes. Leaf blade 20-110 x 3-7 mm, narrowly lanceolate, soft and thin. Inflorescence open to loosely contracted, not spike-like; spikelet distinctly pedicellate. Spikelet 2.0-3.5 mm long, conspicuously asymmetrical, laterally compressed, glabrous to slightly hairy; lower glume a tiny scale 0.2-0.5 mm long; upper glume more than 5 x longer than lower glume, gibbose at base, prominently ribbed; lower floret male; anthers 0.6-1.0 mm long.
Perennial, geniculately ascending from a slender rhizome; culms weak, 20–75 cm. high.. Leaf-blades linear to narrowly lanceolate, 3–11 cm. long, 3–12 mm. wide, rounded at the base.. Panicle open and ovate to contracted and linear, 4–17 cm. long, 1–10 cm. wide, the branches ± wavy.. Spikelets laterally compressed, obliquely oblong in profile, 2–3 mm. long, soon gaping, glabrous or with a few scurfy hairs; lower glume a tiny ovate scale, 0.2–0.5 mm. long; upper glume saccate at the base, herbaceous, prominently ribbed; lower floret male.
