Leaf-sheaths glabrous on surface. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades oblong; 15–17 cm long; 38–41 mm wide; mid-green and glaucous; discolorous with last colour beneath. Leaf-blade venation with 14–16 secondary veins. Leaf-blade surface scabrous; pubescent.
