Tufted annual, up to 900 mm high, erect to sprawling; occasionally rooting at nodes. Leaf blade up to 300 x 20 mm, expanded or folded, glabrous, dark green. Inflorescence a 100-350 mm long, oblanceolate to narrowly obovate panicle, open, profusely branched with many spikelets; well exserted from uppermost leaf. Spikelets 2.0-2.5(-3.5) mm long, obtuse, dorsiventrally compressed, glabrous, light green often tinged with purple, rarely entirely purple; apex of glumes not recurved; lower glume 1/4 as long as spikelet, broadly ovate, cuff-like, 1-nerved; upper glume (7-)9-11-nerved. Florets 2; lower floret male or both male and sterile occurring in same inflorescence, lemma (7-)9-11-nerved, palea well developed; upper floret bisexual, lemma indurated, pale to yellow to light brown, shiny, entire, margins only clasping edges of palea. Flowering time Nov.-May.
