Leaf-sheaths striately veined; glabrous on surface; outer margin hairy. Ligule an eciliate membrane. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 7.5-12 cm long; 9-20 mm wide. Leaf-blade venation prominent; with 8 secondary veins. Leaf-blade surface scabrous; rough adaxially; glabrous, or puberulous; hairy abaxially. Leaf-blade margins scabrous. Leaf-blade apex acute.
- Morphology Reproductive morphology Inflorescences
