    Inflorescences
    Inflorescence a panicle. Panicle open; lanceolate, or pyramidal; 7-20 cm long. Primary panicle branches spreading. Panicle axis scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; scaberulous.
    Spikelets
    Spikelets comprising 3-5 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 4-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2 mm long. Floret callus brief.
    Fertile
