Description: 

Highly branched slightly tufted erect annual of 0.3-0.9 m tall with leaves and sometimes culms conspicuously hairy all over. Culms green to purplish, grooved opposite the emergent branches, sometimes prop-rooted at the base. Leaves linear-lanceolate, flat to partially folded and keeled, 12-20 cm long and 7-12 mm broad, with finely recessed midrib and hairy throughout, base broadly rounded, clasping the culm; ligule a short truncate ciliate membrane; sheath slightly compressed, hairy throughout and keeled. Roots well developed.

* Inflorescence in false panicles, composed of numerous solitary spike-like spatheolate terminal racemes, often with several flowering branches clustered together. Racemes 12-17 mm long with a fragile rhachis and  a typical zig zag structure of the sessile spikelets. Internodes and pedicels fused.

* Spikelets heteromorph. Sessile spikelets globular with tubercles of 1.2-2 mm long, yellow green. Lower glume coriaceous; upper glume ovate and obtuse, verrucose, cartilaginous, narrowly crested at the apex, in a cavity of the internode. Lemma and paleas hyalines, smaller than glumes. Pedicelled spikelets lanceolate, 1.7-2 mm long, glumes herbaceous with prominent nerves and membranous margins.
