    Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 16-25 mm long; 8-10 mm wide; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse; disarticulating obliquely.
    Fertile
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 16-25 mm long; 8-10 mm wide; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse; disarticulating obliquely.
    Glume
