Description Rhizome caespitose, with short internodes. Stems 50-90 cm, ± stout, trigonous, smooth, green to yellowish-green. Leaves 13-26 cm × 7-9 mm, keeled to plicate, very rigid and coriaceous, with revolute margins, slightly scabrid on the edges and apical parts; sheaths reddish-brown to purplish-red; ligule 4-6.5 mm, acute; anteligule edge concave. Inflorescence 8.5-20.5 cm, lowest internode 4.5-11.5 cm and second one 2-3.5 cm. Lowest bract 8.5-13.5 cm × 3-6 mm, shorter or longer than the inflorescence; sheath 4-5 cm long, the inner side purplish-red. Spikes 5-8, heteromorphic, 1 male (sometimes gynecandrous) terminal spike and 4-7 female lateral spikes; terminal spike 2.2-3.5 cm × 3.5-4.5(11) mm, terete, sessile or with a peduncle up to 1 cm; lateral spikes, 1-5 cm × 9-10 mm, dense-flowered, terete, arising singly or in pairs, peduncle up to 4.5 cm. Male glumes 5.5-8 × 1.2-2.2 mm, oblong-elliptic, dark purplish-red with very wide and straw coloured midrib, acuminate, acumen up to 1.5 mm. Female glumes 4-7.2 × 1.2-1.8 mm, oblong-elliptic, dark purplish-red, with a wide and straw coloured midrib and an acumen up to 2 mm. Utricles 4.3-5 × 1-1.5 mm, ellipsoid-trigonous, straight, plurinerved, although the veins are not very prominent, tapered to beak, brown to reddish-brown; beak 1-1.6 mm, smooth truncated or bidentated, with ventral sinus deeper than the dorsal one, the latter up to 0.2 mm depth. Achenes 2-2.4 × 0.9-1.1 mm, trigonous, oblong-ellipsoid to oblong-obovoid. 2n = ? [details]
