Leaf-blades lanceolate; 4-6 cm long; 3-5 mm wide; glandular (beneath). Leaf-blade surface scabrous; rough adaxially. Leaf-blade margins scabrous; tuberculate-ciliate; hairy at base.
    Inflorescences
    Inflorescence a panicle; terminal and axillary. Panicle open; ovate; effuse; 5-7 cm long; 4-5 cm wide; bearing few spikelets. Primary panicle branches spreading; 1 -nate. Panicle branches glandular; scabrous; bearded in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels clavate; pubescent.
    Spikelets

    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; with a barren rhachilla extension. Spikelets elliptic; dorsally compressed; acuminate; 2.7-3 mm long; 0.9 mm wide; falling entire.
    Glume
