Sheaths usually glabrous, sometimes sparsely pubescent, rarely densely pubescent. Panicles to 55.5 cm long, usually 6.7-13.9 times as long as wide; branches to 23 cm long, erect or ascending, at least in the upper 1/3 of the panicle. Spikelets usually without a brownish cast, relatively closely imbricate.

Distribution
