Leaf-blades linear, or lanceolate; 5–15 cm long; 3–6 mm wide. Leaf-blade venation with 7–9 secondary veins. Leaf-blade surface glabrous. Leaf-blade margins cartilaginous; scaberulous; glabrous, or ciliate; hairy at base. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; effuse; 6–8 cm long. Panicle branches capillary; glabrous in axils, or pubescent in axils; with prominent pulvini.
