Perennial, scrambling; leaves cauline; culms up to 400 mm long, branched, rooting at the nodes; nodes yellow, glabrous. Leaf blades flat, lanceolate, 20-85 x 4-9 mm, acuminate, base cordate, then narrowing at junction with sheath; cross-venation present (obvious on abaxial surface); long, rigid hairs present or absent; margins pale, densely scaberulous, often crinkled, usually with dense long hairs at base; sheaths convolute, outer margins densely hairy. Inflorescence 35-145 x 20-180 mm, delicate, open, sparsely branched, closely associated with flag leaf or well exserted; branches long, fine; spikelets solitary, pedicels (4)6-15 mm long, slightly thickened at apex. Spikelet 1.8-2.4 mm long, acute to acuminate; lower glume nearly as to longer than spikelet, 3-nerved, long-acuminate, not clasping; upper glume longer than spikelet, 7-nerved, hardly separated from lower glume; lower floret sterile, lemma 5-7-nerved; palea absent or reduced to a small scale; upper lemma shorter than lower lemma, pallid to light brown, shiny.
