    Inflorescences
    Inflorescence a panicle; subtended by a spatheole; enclosed. Panicle contracted; linear; secund; 7-8 cm long. Panicle axis puberulous. Panicle branches angular; puberulous. Spikelets spreading; solitary. Fertile spikelets pedicelled. Pedicels angular; 1.5-6 mm long; puberulous.

    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 7.7-9.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.2-0.3 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.3-0.4 mm long; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex acute.
