Description Rhizomes from dense and tussock-forming to elongated. Stems (48)60–80(95) cm long, (0.8)1–1.2(1.3) mm wide below the inflorescence,
sharply trigonous, smooth for most of its length, densely scabrid above. Basal sheaths scale-like, sometimes elongated, creamy-yellow, rarely reddish-brown, coriaceous.
Leaves (1.8)2–3.2(4.7) mm wide, pale green to bluish-green, amphistomatic,
flat to keeled, usually shorter or equalling the stems, antrorsely scabrid on the margins,
especially distally, and on the mid-vein on the abaxial side to the apex; ligule (2)3–
7(10) mm long, usually more than twice as long as wide, apex acute to obtuse, rarely
rounded or truncate, hyaline, the margins brownish to orange-brown. Inflorescence
(9)12–19(22) cm long, all spikes erect, exceptionally the lowermost slightly nodding.
Lowest bract leaf-like, very rarely setaceous, longer to shorter than the inflorescence,
sheathless, with hyaline, pale brownish to dark purplish-brown auricles at its base. Terminal
male spikes (1)2–3; the uppermost spike (15)20–60(85) × 2–3.5 mm, subsessile
to long pedunculate, oblong-cylindrical to narrowly fusiform, densely flowered; subterminal
male spikes (0)1–2, (5)10–30(33) × (1)1.5–2.3(2.6) mm, similar in outline to
the terminal one, basally overlapping with it or with an internode up to 20 mm. Lateral
spikes female or androgynous with the flowers spirally arranged; female spikes 0–2(3),
(19)25–50(79) × (2)2.8–4(5.2) mm, cylindrical, densely to more or less laxly flowered
proximally; androgynous spikes (0)1–3(4), (9)20–50(62) × (1)1.7–2.7(5) mm, with
the male portion (1)3–15(50) mm long and the female one (6)10–40(50) mm long.
Male glumes (1.9)2.3–3.9(4.1) × (0.6)0.7–1.2(1.4) mm, oblong to obovate-oblong,
apex rounded, usually dark purplish brown, with a green, 1-veined central band, with
or without whitish hyaline margins, sometimes also becoming hyaline towards the
base. Female glumes 1.3–2.3(2.5) × (0.6)0.7–0.9(1) mm, lanceolate to ovate, rarely
elliptical, apex obtuse, acute or mucronate, usually shorter and narrower than the utricles,
very rarely shortly exceeding them, dark purplish brown, rarely pale brown, with
a green, 1–3 veined central band, with or without whitish hyaline margins, mainly in
the distal part. Utricles (1.8)2–2.7(3) × (1.1)1.3–1.8(2) mm, plano-convex, widely
elliptical to almost suborbicular, green to straw-coloured, distally whitish, sometimes
purplish-dotted or purplish-tinged towards the apex, with high, whitish papillae on
the upper half or towards the apex, sometimes also aculeolate at the upper margins,
faintly to conspicuously nerved, shortly stipitate, more or less abruptly contracted into
a short, cylindrical, truncate, more rarely emarginate beak (0)0.1–0.2(0.3) mm long,
whitish, sometimes brown-tinged. Achenes 1.5–2.1 × (1.1)1.3–1.5(1.7) mm, widely
elliptical to suborbicular, straw-coloured to pale brown, biconvex, more or less stipitate;
style base terete to slightly conical, up to 0.3 mm. Stigmas 2. [details]
