Description Rhizome caespitose, with short internodes. Stems 15–59 cm, stout, trigonous, green to yellowish-green, smooth, sometimes purplish-red spotted. Leaves 10–18 cm × 4–8 mm, keeled, sometimes slightly plicate in the upper half, rigid and markedly coriaceous, scabrid on the edges and apical parts; lower sheaths dark purplish-red; ligule 0–5.5 mm, obtuse to acute; anteligule edge concave to flat. Inflorescence 6.2–18.5 cm, lowest internode 0.8–3.5 cm and second one 0.5–2.5 cm. Lowest bract 5.5–17 cm × 2.5–6 mm, longer or shorter than inflorescence; sheath 1–7.5 cm long, the inner side purplish-red. Spikes 3–10, heteromorphic to subhomomorphic, with 0–2 male or gynecandrous spikes at the apex, and 3–9 female lateral spikes; male or gynecandrous spikes 3–6 cm × 6–12 mm, terete to widely ellipsoid or obovoid, the terminal one sessile or with a peduncle up to 1.2 cm; female spikes, 1–6.5 cm × 6–10 mm, arising singly, dense-flowered, terete to obovoid, sessile or with a peduncle up to 1(3.5) cm. Male glumes (4.5)5.5–9 × 1.2–2 mm, oblong-elliptic to oblong-obovate, dark purplish-red with a wide, green or straw coloured midrib, mucronate or aristate, with a mucro or arista up to 1.7 mm or, more rarely, obtuse. Female glumes (4)5.5–6.5 × 1.1–2.2 mm, ovate-elliptic, dark purplish-red with a wide, green or straw coloured midrib, with an arista or mucro 0.5–2.3 mm. Utricles (4)4.5–6.2 × (1.2)1.4–2(2.1) mm, ellipsoid-trigonous, straight, plurinerved (with 2 more prominent veins), tapered to beak, brown with purplish speckles to entirely purplish; beak (0.9)1.2–1.6 mm, deeply bifid, with ± similar dorsal and ventral sinus 0.4–0.6 mm, densely aculeolate. Achenes 2.2–2.3 × 0.9–1.2 mm, trigonous, elliptic or elliptic-obovate in outline. [details]
