Description Rhizome woody, oblique. Culms tufted, 70-80 cm tall, slender, basal sheaths dark brown, bladeless. Leaves shorter than culm, blades linear, 2-3 mm wide, flat, scabrous.

Female glumes brown, oblong, 3.2-3.5 mm, green 3-veined costa excurrent into a mucro. Utricles longer than glume, obovate-oblong, trigonous, 4.2-4.5 mm, hirsute, nerveless except for 2 costas on edges, base gradually attenuate into a short stipe, apex abruptly contracted into a brown long beak, orifice white hyaline, 2-toothed.
