    Fertile
    Spikelets comprising 2-6 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 4-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas; smooth. Floret callus glabrous.
    Glume
