Scrambling annual, up to 2 m long, decumbent to semi-erect, rooting at nodes. Leaf blade up to 100 x (5-)8-28 mm, abruptly or asymmetrically narrowed at base. Inflorescence an open panicle, 100-250 mm long; finely and usually profusely branched, extending beyond uppermost leaf. Spikelets 1.5-2.5 mm long, asymmetrical, dorsiventrally compressed, glabrous or hairy; lower glume 1/2 length of spikelet, separated from rest of spikelet by a short internode, 3-nerved; upper glume 5-nerved. Florets 2; lower floret sterile, lemma 5-7-nerved, palea reduced or poorly developed; upper floret bisexual, lemma indurated, pale and granulose, margins only clasping edges of palea. Flowering time Jan.-Apr. (June, July.
Scrambling annual to 2000 mm; decumbent to semi-erect; rooting at nodes. Leaf blade to 100 x (5-)8-28 mm, abruptly or asymmetrically narrowed at base. Inflorescence open, 100-250 mm long, extending beyond uppermost leaf; finely and usually profusely branched. Spikelet 1.5-2.5 mm long, asymmetrical, glabrous or hairy; lower glume 1/2 the spikelet length, separated from rest of spikelet by a short internode, 3-nerved; upper glume 5-nerved; lower floret sterile, lemma 5-7-nerved, palea reduced or poorly developed; upper lemma pale, granulose.
Annual, scrambling, decumbent to semi-erect, rooting at nodes, culms up to 2 m long. Leaf blades up to 100 mm long, (5-)8-28 mm wide. Leaves abruptly or asymmetrically narrowed at base. Spikelets 1.5-2.5 mm long. Inflorescence extending beyond uppermost leaf, open, finely and usually profusely branched; lower glume half the length of spikelet, separated from rest of spikelet by a short internode; upper glume 5-nerved; lower floret sterile, lemma 5-7-nerved and palea reduced; female-fertile (upper) lemma pale and granulose.
Spikelets 1.5–2 mm. long, asymmetrically narrowly ovate, glabrous or pilose; inferior glume 5 the length of the spikelet, 3-nerved, separated from the superior glume by a short internode; superior glume 2/3–3/4 the length of the spikelet, 5-nerved; inferior lemma 5–7-nerved, its palea poorly developed, sterile; superior lemma and palea coriaceous, granulose, pallid, the apiculate apex generally exposed.
