Plants annual; tufted, without innovations. Culms 8-45(70) cm, erect or geniculate, glabrous, occasionally with a few glandular depressions. Sheaths mostly glabrous, occasionally glandular, apices hirsute, hairs to 3 mm; ligules 0.1-0.3 mm, ciliate; blades 2-15(20) cm long, 1-2.5(4) mm wide, flat, abaxial surfaces glabrous, occasionally with glandular pits along the midrib, adaxial surfaces scabridulous. Panicles 4-20(28) cm long, 2-15(18) cm wide, ellipsoid to ovoid, diffuse; primary branches 1-10 cm, diverging 10-80°(110°) from the rachises, capillary, whorled on the lowest 2 nodes, rarely glandular; pulvini glabrous or hairy; pedicels 1-10 mm, flexible, appressed or divergent. Spikelets (2)3.5-6(10) mm long, 0.6-1.4 mm wide, linear-oblong to narrowly ovate, plumbeous, with (3)5-17 florets; disarticulation acropetal, paleas tardily deciduous, rachillas persisting longer than the paleas. Glumes narrowly ovate to lanceolate, hyaline; lower glumes 0.3-0.6(0.8) mm; upper glumes 0.7-1.2(1.4) mm; lemmas 1.2-1.8(2) mm, ovate-lanceolate, membranous to hyaline, grayish-green proximally, reddish-purple distally, lateral veins inconspicuous, apices acute; paleas 1-1.6 mm, membranous to hyaline, keels scabridulous to scabrous, apices obtuse; anthers 3, 0.2-0.3 mm, purplish. Caryopses 0.5-1 mm, obovoid to prism-shaped, adaxial surfaces flat, smooth to faintly striate, light brown. 2n = 40.
