Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; puberulous; 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; globose; 3.8-8.1 mm long; base obconical (0.5-1.5mm); base glabrous. Involucral bristles deciduous with the fertile spikelets; in one whorl; 3-5.8 mm long; flattened; rigid; retrorsely scaberulous; glabrous; spinose.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 3.8-5.6 mm long; falling entire; deciduous with accessory branch structures.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 3.8-5.6 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1.5-3 mm long; 0.5 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 3-5 mm long; 0.75-0.9 length of spikelet; membranous; without keels; 3-5 -veined. Upper glume apex acute.
    Florets
    Basal sterile florets barren; with palea. Lemma of lower sterile floret ovate; 3.1-5.5 mm long; 0.9-1 length of spikelet; membranous; 3-7 -veined; acute. Fertile lemma ovate; 3.8-5.4 mm long; coriaceous; much thinner on margins; without keel; 3-5 -veined. Lemma margins flat. Lemma apex obtuse. Palea coriaceous.
