Sheaths glabrous or pubescent; ligules 1.2-3.3 mm; blades to 52 cm long, 3-18 mm wide, flat, glabrous or pubescent, usually densely pubescent behind the ligules. Panicles terminal, with 1-6 racemosely arranged branches; branches 3-17.9 cm, divergent to erect, terminating in a spikelet; branch axes 0.3-1.8 mm wide, glabrous, the margins scabrous. Spikelets 2.9-4.1 mm long, 1.9-3.1 mm wide, paired, imbricate, appressed to the branch axes, elliptic to suborbicular to orbicular, glabrous, stramineous. Lower glumes absent; upper glumes glabrous, 5-veined, margins entire; lower lemmas glabrous, lacking ribs over the veins, 3-veined, margins entire; upper florets golden brown.
