Culm-sheath ligule 2 mm high; ciliolate. Culm-sheath blade lanceolate, or triangular; scabrid. Leaves 4-8 per branch. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs setose; spreading; 4-5 mm long. Ligule an eciliate membrane; 2 mm long; pubescent on abaxial surface. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 10-16 cm long; 15-23 mm wide. Leaf-blade venation with 8-10 secondary veins. Leaf-blade surface glabrous; hairless except near base. Leaf-blade apex attenuate.
    Inflorescences
