    Inflorescences
    Inflorescence a panicle; comprising 2-10 fertile spikelets. Panicle open; linear; 2-4 cm long; bearing few spikelets. Primary panicle branches indistinct the panicle almost racemose. Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels 4-7 mm long.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5-5.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5-5.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
