    Spikelets
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4.3-6.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
    Fertile
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4.3-6.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
    Glume
