"Nearly glabrous perennial [grass]; culms to 50 cm long, somewhat branched at base; pubescent just beneath the panicle; blades linear, 10-24 cm long with hairs near the ligule, the ligule of short hairs; sheaths slightly flattened, glabrous; panicle cylindric, to 10 cm long, yellow, the axils pilose-scabrous with spreading bristles 8-10 mm long beneath each spikelet; spikelets ovate, 2-2.5 mm long, pale; first glume 3-nerved, half as long as the spikelet; second glume 5-nerved; sterile lemma equaling the spikelet and 5-nerved; fertile lemma ovate, finely rugulose, obtuse, shiny" (Stone, 1970; pp. 224-225).

Description from GrassBase.

Habitat/ecology:  "Infests dryland crops, roadsides, waste areas, ditches and occasionally grasslands.  It is adapted to a wide range of soils and climates and is especially well suited to dry soil conditions"  (Holm et al., 1997; p. 767).

Tonga, "occasional in open areas" (Yuncker, 1959; p. 62). In New Caledonia, "commun en terrains vagues et bords de chemins" (MacKee, 1994; p. 62).
