Plants annual; weak, ascending or sprawling. Culms 10-150 cm, slender, wiry, erect at first, ultimately decumbent, sprawling, glabrous, often with purple dots and streaks, branching extensively at the base, rooting at the lower nodes. Sheaths often shorter than the internodes, loose, glabrous, margins short-ciliate; ligules 0.2-0.5 mm, membranous, erose, ciliate; blades 5-20 cm long, 3-10 mm wide, thin, flat, glabrous on both surfaces, margins scabridulous, apices long-acuminate. Panicles 5-30 cm, nearly as wide as long; branches few, capillary, with a few spikelets distally; pedicels 0.5-10 mm. Spikelets 1.7-2.2 mm long, about 1 mm wide, ellipsoid or obovoid, glabrous, faintly veined, subacute or obtuse at the apices. Lower glumes 0.3-0.8 mm, reduced, acute; upper glumes and lower lemmas subequal or the glumes shorter, distinctly verrucose, with hemispheric warts; upper florets 1.6-2 mm long, about 1 mm wide, grayish-brown, dull, minutely papillose, acute. 2n = 36.
