Leaf blade to 150 x (5)10-25 mm, lanceolate to narrowly ovate, cross-veins present, base rounded, apex acuminate. Inflorescence 100-250 mm long; sparsely and irregularly branched, ascending to spreading, scabrid; exserted from uppermost leaf; spikelets adpressed to branches. Spikelet 2.2-3.5(-4.0) mm long, glabrous, acuminate to apiculate; lower glume broadly ovate, rounded, 1/4-1/2(2/3) the spikelet length, 0-1-nerved, not clasping; upper glume 5-nerved; lower floret sterile, lemma 5-nerved, palea variable but mainly absent or rudimentary; upper lemma pale or light brown, smooth, shiny.
Perennial, trailing, decumbent, rooting at nodes, culms 1 m long. Leaf blades up to 150 mm long, (5-) 10-25 mm wide. Spikelets 2.2-3.5(-4.0) mm long. Inflorescence sparsely and irregularly branched, exserted from uppermost leaf; lower glume broadly ovate, a quarter to half the spikelet length, 0 or 1-nerved; upper glume and lower lemma 5-nerved; lower floret sterile with palea absent or rudimentary; female-fertile (upper) lemma pale, smooth and shiny.
Spikelets 2.2–3.5 mm. long, ovate to ovate lanceolate, acuminate; inferior glume 1/4–1/2(2/3) the length of the spikelet, 0–1-nerved; superior glume 5-nerved; inferior lemma 5-nerved, sterile, its palea absent or rudimentary; superior lemma and palea pallid, glossy.
