Leaf-sheath oral hairs lacking. Leaf-sheath auricles erect. Ligule a ciliolate membrane; 0.25-0.5 mm long. Collar glabrous. Leaf-blades erect; conduplicate; 4-11 cm long; 0.3-0.75 mm wide; 1.5-3 cm long at summit of culm; stiff; glaucous. Leaf-blade venation comprising 5-7 vascular bundles; with 1 inner ridges; with sclerenchyma strands below veins; with 5-7 subepidermal sclerenchyma strands; with subepidermal sclerenchyma free from veins; with sclerenchyma strands widened to form a discontinuous subepidermal layer, or with continuous uniform subepidermal sclerenchyma layer on the underside. Leaf-blade surface glabrous. Leaf-blade margins glabrous.
