Ligule a fringe of hairs. Leaf-blades 3-6 cm long; 1-3 mm wide; flaccid; glandular. Leaf-blade surface hirsute; hairy adaxially; with tubercle-based hairs. Leaf-blade margins smooth. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle; comprising 30-100 fertile spikelets. Panicle open; ovate; 2-6 cm long; 2-5 cm wide. Panicle branches glabrous in axils, or pubescent in axils, or bearded in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 0.75-1.5 length of fertile spikelet; glandular; glabrous, or pubescent.
    Spikelets
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 2.5-5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Fertile
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 2.5-5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
