Description Rhizome caespitose, with short internodes. Stems 23–107 cm, ± stout, trigonous, smooth, green to yellowish-green. Leaves 8–21 cm × 3–6 mm, keeled to plicate, some rigid, slightly scabrid on the edges and apical parts; sheaths straw coloured to dark purplish to blackish; ligule 2.5–4 mm, obtuse or acute; anteligule edge concave to convex. Inflorescence 8.5–27.5 cm, lowest internode 3–11.5 cm and second one 1.5–8 cm. Lowest bract 6.5–20 cm × 2–5 mm, shorter than or as long as the inflorescence; sheath 1–7.5 cm long, the inner side purplish-red. Spikes 5–7, heteromorphic, 1–3 male spikes at the upper part and 3–6 female lateral spikes, frequently with a few male flowers at the top; male spikes 1–4 cm × 4–8 mm, linear to terete, the terminal one sessile or with a peduncle up to 2.3 cm; lateral female or androgynous spikes, 2.5–5.5 cm × 7–10 mm, arising singly (exceptionally in pairs), subdense-flowered, oblong-terete to ovoid-terete, peduncle up to 5 cm. Male glumes 5.5–9.2 × 1.2–1.8 mm, oblong, dark purplish to blackish without midrib or with a very narrow and straw coloured midrib, acuminate or aristate, acumen or arista up to 1.6 mm. Female glumes 4.5–6.5 × 0.9–1.9 mm, oblong-lanceolate, dark purplish to blackish, without midrib or with a very narrow and straw coloured midrib, acuminate or aristate, acumen or arista up to 1 mm. Utricles 4–6.2 × 1–1.5 mm, ellipsoid to obovoid-trigonous, straight, plurinerved, gradually to abruptly narrowed into a beak, straw coloured in the lower portion and dark purplish to blackish in upper parts, sometimes entirely dark purplish or blackish; beak 0.8–1.9 mm, bifid, with ± similar dorsal and ventral sinus 0.2–0.5 mm depth, smooth or with disperse and short pricklets. Achenes 2–2.3 × 0.9–1.1 mm, trigonous, ellipsoid to obovoid. [details]
