    Habit
    Perennial. Rhizomes elongated. Culms erect; 100-200 cm long. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs. Leaf-blades curled; involute; 3-10 mm wide; coriaceous; stiff. Leaf-blade margins scabrous.
    Inflorescences
    Inflorescence composed of racemes. Racemes numerous; borne along a central axis; closely spaced; in a multilateral false spike; unilateral; 1-3 cm long; simple. Central inflorescence axis (10-)20-50(-80) cm long. Spikelet packing broadside to rhachis; crowded. Spikelets in pairs. Fertile spikelets sessile. Pedicels oblong.
    Spikelets
    Spikelets comprising 1-5 basal sterile florets; (1-)2-5(-7) fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; compressed strongly; 4-5 mm long; 1.5-3 mm wide; falling entire. Rhachilla internodes obscured by lemmas.
    Fertile
    Spikelets comprising 1-5 basal sterile florets; (1-)2-5(-7) fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; compressed strongly; 4-5 mm long; 1.5-3 mm wide; falling entire. Rhachilla internodes obscured by lemmas.
    Glume
    Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1-2 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface glabrous, or puberulous. Lower glume apex acute. Upper glume ovate; 1-2 mm long; 0.4-0.66 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface glabrous, or puberulous. Upper glume apex acute.
    Florets
    Basal sterile florets similar; barren; without significant palea. Lemma of lower sterile floret similar to fertile lemma; ovate. Fertile lemma ovate; 2.5-3 mm long; cartilaginous; keeled; 3-5 -veined. Lemma lateral veins obscure. Lemma surface glabrous, or puberulous. Lemma apex truncate, or obtuse; muticous, or mucronate. Palea 0.9-1.1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 1-2 mm long.
    Fruits
    Caryopsis with adherent pericarp; ovoid; 1 mm long.
