Inflorescences to 60 cm, nodding; rames 10-25 mm; internodes and pedicels pilose on the margins and dorsal surface. Sessile spikelets of heterogamous pairs 5-6 mm; lower glumes shallowly concave below, flat distally, keels narrowly winged; upper lemmas entire or bidentate, unawned or with a 1-2 mm awn.
