Collar pubescent. Leaf-blades linear, or lanceolate; 5-12 cm long; 6-10 mm wide. Leaf-blade midrib conspicuous. Leaf-blade surface glabrous, or pubescent. Leaf-blade margins scabrous. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; effuse; 3.5-15 cm long; 3-10 cm wide. Primary panicle branches whorled at lower nodes. Panicle axis eglandular, or glandular; glabrous. Panicle branches flexuous; eglandular, or glandular; glabrous; glabrous in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels eglandular, or glandular; glabrous.
    Spikelets

    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.8-2.8 mm long; 0.8 mm wide; falling entire.
    Glume
