Leaf-blades convolute; 7-22 cm long; 2-3 mm wide. Leaf-blade venation with sclerenchyma strands widened to form a discontinuous subepidermal layer, or with continuous uniform subepidermal sclerenchyma layer on the underside.

Floret callus hairs 0.3 mm long; 0.05 length of lemma.
    Glume
    Glumes persistent; similar; reaching apex of florets; firmer than fertile lemma. Lower glume lanceolate; 3.6-4.2 mm long; 0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume surface hispidulous. Lower glume apex obtuse. Upper glume lanceolate; 3.8-4.4 mm long; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume lateral veins ribbed. Upper glume surface hispidulous.

Principal lemma awn dorsal; arising 0.5-0.75 way up back of lemma; straight; 1.4-1.7 mm long overall; not or scarcely exserted from spikelet. Palea 2-3.4 mm long. Rhachilla extension 0.7-1.5 mm long; pilose; with 1.2-1.4 mm long hairs.
