Plants annual. Culms 20-120 cm, geniculate or decumbent, usually rooting at the lower nodes; nodes glabrous. Sheaths glabrous or glabrate, margins ciliate distally; ligules 0.5-1 mm; blades 2-20 cm long, 7-20 mm wide, glabrous. Panicles terminal and axillary, 5-18 cm long, to 1.4 cm wide, with 2-10 spikelike primary branches in more than 2 ranks; primary branches 1.5-9 cm, appressed, axes 0.3-0.8 mm wide, triquetrous, scabrous; secondary branches present or absent, if present, short, restricted to the lowest panicle branches; pedicels scabrous, shorter than the spikelets. Spikelets 2.9-3.8 mm long, 1.2-1.4 mm wide, ellipsoid, apices abruptly acuminate, mostly paired, in 2-4 rows, appressed to the branches. Glumes scarcely separate, rachilla internodes short, not pronounced; lower glumes 1-1.4 mm, glabrous or pubescent, (3)5-veined, 1/3 or less as long as the spikelets; upper glumes 2.8-3.7 mm, glabrous or pubescent, 5-7(9)-veined, cross venation not evident or evident only in the distal 1/2; lower florets sterile; lower lemmas 2.7-3.6 mm, glabrous or pubescent, 5-veined, usually without cross venation; upper florets 2.1-2.9 mm long, 1.3-1.7 mm wide, broadly acute, mucronate; anthers 1-1.2 mm. Caryopses 1.2-1.8 mm; hila punctiform. 2n = 54.
