Description Rhizomes far-creeping, forming large stands; shoots loosely tufted, slender; roots pale yellow-brown; scales pale or yellow-brown, occasionally wine-red. Stems 45–120 cm, slender, stiff, smooth or slightly rough above, trigonous, striate. Leaves 30–100 cm × 1–2 mm, flat or more usually inrolled, long attenuate into a fine acicular, stiff, whip-like point which lies flat when en masse, giving a characteristic striate texture to the mire community, grey-green; hypostomous; sheaths dark purple-brown to pale red-brown, soon decaying, with inner face membranous, purple- or pale brown, persistent or often fibrillose, and apex straight, dark purplish; ligule 2–3 mm, obtuse. Inflorescence 1/8–1/6 length of stem; bracts leaf-like, very slender, lower often exceeding inflorescence. Male spikes 1–3, ± contiguous, 20–70 mm; male glumes 4–6 mm, lanceolate, purple-brown, with a green or pale midrib; apex acute. Female spikes 1–3, contiguous or ± distant, 10–30 mm, cylindric-oblong, erect, ± sessile; female glumes 3.5–5 mm, lanceolate, chestnut-brown, with a pale midrib; apex acute or acuminate. Utricles 3.5–4.5 mm, ovoid, tomentose, grey-green; beak 0.5–1 mm, ± deeply bifid; stigmas 3; nut ovoid, trigonous. [details]

Description Rhizome stoloniferous. Culms laxly tufted, 50-100 cm tall, obtusely trigonous, stiff, slightly scabrous on upper part, with red-brown and bladeless sheaths at base, sheaths later splitting into reticulate fibers. Leaves shorter than or nearly equaling culm, blades 1-2 mm wide, involute on margins, slightly plicate, stiff, with transverse septate nodes between veins, rather long sheathed. Involucral bracts leafy, linear, nearly equaling or slightly longer than inflorescence, lower involucral bracts up to 5 mm sheathed, upper involucral bracts nearly not sheathed. Spikes 3-5; terminal 1-3 spikes male, approximate, linear-cylindric, 2-3 cm, subsessile; remaining spikes female, remote, ovate or oblong-cylindric, 1.5-3 cm, 5-6 mm thick, densely many flowered, shortly pedunculate, upper ones subsessile. Female glumes brown or red-brown laterally, green at middle, oblong-ovate or lanceolate, 4.5-5 mm, membranous, 3-veined, apex acuminate, mucronate. Utricles yellow-green, obliquely patent, slightly shorter than or nearly equaling glume, ovate or oblong-ovate, slightly inflated trigonous, 4-5 mm, leathery, densely brownish gray tomentose, indistinctly veined, base obtusely rounded, apex gradually narrowed to a slightly broad and short beak, orifice slightly recurved 2-toothed. Nutlets rather tightly enveloped, obovate, trigonous, ca. 2 mm, base shortly stipitate; style short, usually curved, base not thickened; stigmas 3. [details]

Male glumes ovate, acute, dark purplish-brown, without scarious margins; female glumes ovate, acute, thin or aristate, dark purplish-brown, without scarious margins. Utricles (3.5)4–5.4(8) × 1.5–1.8 mm, suberect, oval in outline, trigonous with convex faces, densely tomentose, dark brown, with nerves well marked, rather abruptly narrowed into a beak (0.3)0.5–0.8(1) mm long, bifid, pilose. Achenes 1.5–1.9 × 1–1.2 mm, oval or obovoid in outline, trigonous, brown. 2n = 56, 78, 80, 81, 82, 84, 85.* [details]
