    Spikelets
    Spikelets comprising 2-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 2-4 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.4 mm long; smooth.
    Fertile
    Spikelets comprising 2-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 2-4 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.4 mm long; smooth.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume ovate; 0.5-0.9 mm long; 0.33-0.5 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 1.5-1.9 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex obtuse.
    Florets
    Fertile lemma ovate; 1.5-1.8 mm long; membranous; much thinner above; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma apex obtuse. Palea 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
