Isachne australis R. Br., Prodr. 196. 1810; Hook. f., Fl. Brit. Ind. 7: 24. 1879; Hayata Icon. Pl. Form. 7: 57.
Culm tufted, branching and rooting at the lower nodes, the flowering culm 30-60 cm long. Blade linear-lanceolate, 2-8 cm long; sheath shorter than the internode, ciliate on the margins; ligule a ring of hairs. Panicle open, with yellowish glandular bands on the panicle branchlets. Spikelets sometimes purplish, about 2 mm long, glumes broadly elliptical, slightly shorter than the spikelet, nerves obscure, glabrous or hispidulous toward the obtuse apex; lower floret staminate, slightly larger and of a thinner texture than the glabrous or pubescent upper floret; anther about 0.9 mm long.

Widely distributed in Southeast Asia, extending to Japan and Australia.
This is a very common aquatic grass growing on the plains, in rice fields and in shallow water, and is acceptable to grazing animals, and since it is common it is of considerable importance. Sometimes it is a troublesome weed in rice fields.
