    Inflorescences
    Inflorescence a panicle. Panicle open; oblong, or ovate; 3-10 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 1.7-2.3 mm long; falling entire. Rhachilla internodes elongated between glumes.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 1.7-2.3 mm long; falling entire. Rhachilla internodes elongated between glumes.
    Glume
