Description Rhizome caespitose, with short internodes. Culms (46)70-190(215) cm, very stout, trigonous, smooth, green to yellowish-green, but densely dark purplish-red spotted or tinted towards the base. Leaves 25-76 cm × 7.5-13.5 mm, plicate, with revolute margins, slightly scabrid on margins and apical parts; sheaths dark purplish-red; ligule up to 6 mm, acute or obtuse; anteligule edge flat to convex. Inflorescence 14-76(98) cm, lowest internode 5-25(31) cm and second one 2.5-17.5(25) cm. Lowest bract 21-40 cm × 3-7.5(10) mm, longer or shorter than the inflorescence; sheath 3-10.5(15.5) cm long, the inner side purplish-red. Spikes 7-22, homomorphic to heteromorphic, 0-6 male spikes at the top and up to 17 female or androgynous spikes; male spikes 1-6.5(11.5) cm × (2)3-7(8) mm, terete, sessile or with a peduncle up to 3.3 cm; lateral spikes, (1)2-9(12) cm × 7-11 mm, dense-flowered, terete, mostly arising in pairs or groups of three, the rest single, frequently with some short branches at the base of the largest spikes, sessile or with a peduncle up to 6 cm. Male glumes (3.5)4.5-6.5 × 1-2 mm, oblong-lanceolate to oblong-obovate, dark reddish-brown to purplish-red with straw or green coloured midrib, mucronate, mucro up to 1.3 mm, or obtuse. Female glumes (3)3.5-5.7 × 1-2 mm, oblong-lanceolate, dark reddish-brown to purplish-red with straw or green coloured midrib, mucronate or acuminate, mucro or acumen up to 1.5 mm, rarely obtuse. Utricles 4-5.5 × 1.2-1.8 mm, ellipsoid to obovoid, clearly curved, tetra-nerved (sometimes plurinerved), gradually or abruptly narrowed into a beak, greyish-green with purplish-red speckles, sometimes entirely purplish in the upper half, trigonous; beak 1-1.8 mm, bifid, with ventral sinus deeper than dorsal one, the latter 0.2-0.5 mm depth, smooth or with some scattered pricklets. Achenes 2.5-3.1 × 0.9-1.2 mm, trigonous, oblong-elipsoid to oblong-obovoid. 2n = ? [details]
