    Spikelets
    Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3-5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.
    Fertile
    Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3-5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.
    Glume
    Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate; 0.5-1.2 mm long; 0.5-0.66 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate; 1-1.8 mm long; 0.66-0.9 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex obtuse.
    Florets

Lemma lateral veins obscure; stopping well short of apex. Lemma margins ciliolate; hairy above. Lemma apex truncate. Palea 1 length of lemma; 2 -veined. Palea keels smooth, or scabrous; adorned above. Apical sterile florets resembling fertile though underdeveloped.
