    Inflorescences
    Inflorescence a panicle; comprising 200 fertile spikelets. Panicle open; ovate; 5-10 cm long; 4-9 cm wide. Panicle branches bearded in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 0.75-1.5 length of fertile spikelet; eglandular, or glandular; smooth, or scaberulous.
    Spikelets
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 3.5-5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Fertile
