Leaf-sheaths 4–7 cm long; keeled; glabrous on surface. Ligule a fringe of hairs. Leaf-blades linear; 7–21 cm long; 6–12 mm wide. Leaf-blade surface glabrous, or hispid. Leaf-blade margins cartilaginous. Leaf-blade apex acute.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 7–13 cm long. Primary panicle branches 3–8 cm long.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels glandular.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets orbicular, or obovate; dorsally compressed; 2–2.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
