Sheaths densely pubescent, occasionally glabrous; ligules 1-2.2 mm; blades to 55 cm long, 2.2-8.3 mm wide, conduplicate (occasionally flat), glabrous below, pubescent above. Panicles terminal, with 2-10 racemosely arranged branches; branches 0.8-10.3 cm, divergent to spreading, often arcuate, terminating in a spikelet; branch axes 0.8-2 mm wide, narrowly winged, glabrous, margins scabrous. Spikelets 2.1-3.1 mm long, 2-2.8 mm wide, paired, imbricate, appressed to divergent from the branch axes, orbicular to suborbicular, stramineous.
