    Spikelets
    Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets linear; straight, or curved; laterally compressed; 30-60 mm long; 4-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
    Fertile
