    Spikelets
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-11 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Fertile
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-11 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
