Panicles terminal, with 3-15 racemosely arranged branches; branches 5.2-12.5 cm, divergent to spreading, terminating in a spikelet; branch axes 0.3-0.8 mm wide, very narrowly winged, scabrous. Spikelets 2.2-2.5 mm long, 1-1.3 mm wide, paired, appressed to the branch axes, elliptic to obovate, white to light stramineous.
