Description Rhizome caespitose, with short internodes. Stems 40-150 cm, ± stout, trigonous, smooth, green to yellowish-green usually with dark purplish-red spotting or tinted towards the base. Leaves (10)15-55(60) cm × (3) 4.5-9.5 mm, keeled to plicate, sometimes slightly rigid, ± scabrid on the edges and apical parts; sheaths dark purplish-red; ligule (1)1.8-6 mm, obtuse to acute; anteligule edge concave to convex. Inflorescence (9)12-59 cm, lowest internode (3)4-20(22) cm and second one 1-15 cm. Lowest bract (5.9)7-65 cm × (1.5) 2-7 mm, shorter or longer than the inflorescence; sheath 2-9.5 cm long, the inner side dark purplish-red. Spikes 4-13, heteromorphic to sub-homomorphic, 0-2 male, gynecandrous or androgynecandrous spikes at the top, up to 12 female or androgynous lateral spikes; terminal spike 2-8 cm × (3)4-10(13) mm, terete, ovoid or ellipsoid, sessile or with a peduncle up to 3(3.5) cm; lateral, female or androgynous spikes, 1-7.5(8.9) cm × 5-11 mm, subdense to dense-flowered, terete to ovoidterete, arising singly or in pairs, at least some of them with a few short branches at the base of the largest spikes, peduncle up to 5.5(7) cm. Male glumes 4-9 × 12(2.2) mm, oblong-elliptic to oblong-obovate, dark reddish-brown to purplish-red with wide, straw or green coloured midrib, mucronate, acuminate or aristate, mucro, acumen or arista up to 1.6 mm, sometimes obtuse. Female glumes (3)3.5-6.5(8) × (0.8)1.1-2(2.2) mm, oblong-elliptic, purplish-red, with green or straw coloured midrib, acuminate or aristate, acumen or arista up to 2.3 mm. Utricles (3.5)3.7-5.2(6) × (1)1.1-1.7(2) mm, elliptic in outline, straight, plurinerved, gradually to abruptly narrowed into a beak, greenish-brown or yellowishgreen with many purplish-red speckles; beak 1-2.1 mm, bidentate to bifid, with ± similar ventral and dorsal sinus 0.2-0.5 mm depth, smooth or with short, scattered prickles. Achenes (1.8)2-3 × 0.8-1.4 mm, oblong-ellipsoid to oblong-obovoid. 2n = 70 [details]
