Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1-3 in the cluster. Involucre composed of bristles; connate into a disc below; with 0.5 mm connate; oblong; 9.8-14 mm long; base truncate (0.5-0.8mm); base glabrous. Involucral bristles deciduous with the fertile spikelets; with an outer whorl of thinner bristles; 5-15 in principal whorl; inner bristles longer than outer; with one conspicuously longer bristle; 6.2-11.4(-25) mm long; expanded (narrowly elliptic, 0.5mm wide); flexible; antrorsely scaberulous; glabrous, or ciliate; attenuate.

    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 5-7.5 mm long; falling entire; deciduous with accessory branch structures.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 5-7.5 mm long; falling entire; deciduous with accessory branch structures.
    Glume
