    Spikelets
    Spikelets comprising 3-18 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 30-100 mm long; 3-6 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 6-7 mm long; glabrous.
    Fertile
    Spikelets comprising 3-18 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 30-100 mm long; 3-6 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 6-7 mm long; glabrous.
    Glume
    Glumes several; 4 empty glumes; persistent; similar; shorter than spikelet. Lower glume ovate; 3 mm long; chartaceous; without keels; 3 -veined. Lower glume surface glabrous. Lower glume apex acute. Upper glume ovate; 16 mm long; chartaceous; without keels. Upper glume apex acute; mucronate.
