Panicles (4.5)7-20 cm long, 1-9.5 cm wide, narrowly ovate; primary branches to 8 cm; pedicels usually shorter than the spikelets, glabrous, scabridulous. Spikelets 1.7-2.4 mm, usually purplish; calluses glabrous. Lower glumes absent or to 0.3 mm, glabrous, scabridulous; upper glumes 1.6-2.4 mm, glabrous, unawned, sometimes muticous; lower florets sterile; lower lemmas bilobed, lobes 0.2-0.7 mm, unawned or awned, awns to 18 mm; lower paleas absent; upper lemmas 1.4-1.9 mm, glabrous; upper paleas 1.5-1.9 mm, usually slightly longer than the upper lemmas; anthers 3, 1-1.5 mm, reddish-brown to orange.
