Fertile spikelets pedicelled. Pedicels oblong; 1-3 mm long; eglandular, or glandular. Fertile spikelets: Spikelets comprising 6-16(-40) fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3-15 mm long; 1.3-2 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas. Rhachilla internodes definite. Glumes deciduous; similar; shorter than spikelet. Lower glume ovate; 1-1.7 mm long; 1 times length of upper glume; eglandular, or glandular (on keel); 1-keeled; 1-3 -veined. Lower glume apex acute. Upper glume ovate; 1-1.7 mm long; 0.7-0.8 times length of adjacent fertile lemma; eglandular, or glandular; 1-keeled; 1-3 -veined. Upper glume apex acute.
