Culm prostrate, rooting at basal nodes, nodes bearded. Blade ovate-cordate, amplexicaul, 1-2.5 cm long, ciliate-serrulate, subcoriaceous, ecostate; sheath shorter than the internode, ciliate along margins; ligule a ring of hairs; about 1.2 mm long.

Spikelets 1-flowered, about 1 mm long; glumes deciduous, membranous; lower glume about 6 mm long, nerveless, glabrous; upper glume naarly as long as the spikelet, 1-nerved; lemma pubescent, about 1 mm long; palea pubescent equaling the lemma; anther about 0.3 mm long. Caryopsis about 0.7 rrim long, ovate, brownish.
