    Plants densely cespitose.
    Culms pale-brown to ivory at base, sometimes with a few brown fibrillose remains of previous year’s leaves, but not densely covered with fibrils;
    flowering-stems 25–110 (–200) cm, longer than leaves at maturity, 1–1.3 mm thick, glabrous.
    Leaves: sheaths glabrous, proximal ones ivory grading distally to light green, all bearing blades, pale hyaline on front;
    blades flat, (3–) 5.5–8.5 (–15) mm wide, glabrous on both surfaces, finely scabrous on margins.
    Inflorescences: peduncles of lateral spikes 5–20 mm, scabrous;
    peduncle of terminal spike less than 20 mm, scabrous;
    proximal bracts usually shorter than entire inflorescence;
    sheaths 20–100 mm;
    blades 2–3 mm wide.
    Lateral spikes: 3–5, 1 per node, the proximal well separated, erect to somewhat nodding, distal ones crowded near apex;
    proximal spikes pistillate with 15–40 spreading perigynia attached 1–1.5 mm apart, cylindric to elongate, 15–60 × 3–5 mm;
    distal spikes staminate or androgynous.
    Terminal spike staminate or androgynous with a few pistillate flowers at base, 15–40 × 2.5–3 mm.
    Pistillate scales white-hyaline with broad green midrib, oblong-lanceolate, shorter than mature perigynia, apex acute, cuspidate, or awned, glabrous.
    Perigynia green maturing to light-brown, conspicuously 2-ribbed but otherwise veinless except for short inconpicuous veins at base, substipitate, tightly enveloping achene, obovoid, 4.5–6 × 1.4–1.8 mm, membranous, apex abruptly narrowed to tubular beak, glabrous;
    beak bidentate, slender, 2–3 mm, teeth 1 mm.
    Achenes sessile, 2.2–2.6 × 1.2–1.5 mm. 2n = 58 (Czechoslovakia, Germany, Great Britain, Iberian Peninsula, Poland, Sweden)
