Description Rhizome short, indurate. Culms densely tufted, 40–80 cm tall, obtusely trigonous, scabrous, clothed at base with several pale brown bladeless sheaths sometimes slightly disintegrating into fibers. Leaves shorter than culm, blades linear, 2–3 mm wide, flat, margins slightly scabrous. Lower involucral bracts leaflike, surpassing inflorescence, upper setaceous or glume-like. Spikes 9–22, gynaecandrous, ovate to oblong-ovate, 5–12 × ca. 3 mm, upper spikes approximate, lower ones remote. Female glumes pale green, ovate or narrowly ovate to lanceolate, ca. 2.5 × 1–1.5 mm, membranous, 1-veined at middle. Utricles pale green, slightly longer than glume, elliptic or elliptic-ovate, plano-convex, ca. 2.5 mm, membranous, spongy, many veined on both faces, base subrounded, upper margins slightly serrulate winged, apex abruptly contracted into a short beak, orifice 2-toothed. Nutlets rather loosely enveloped, elliptic, base subcuneate; style base slightly thickened; stigmas 2. Fl. and fr. May-Jul. [details]

Description Rhizomes short, woody. Culms caespitose, 25–70 cm tall, obtusely trigonous, smooth or scabrous, base with pale brown or brown fibrous sheaths. Leaves shorter than or nearly equal to culms; blade 1–3 mm wide, flat, soft, margin scabrous, apex acuminate. Lower bracts leaflike, longer than inflorescence, sheathless, upper ones setaceous or scale-like. Spikes 5–15(–22), gynaecandrous, ovoid or oblong-ovoid, 3–12 mm long, 3–4 mm wide, sessile. Pistillate scales ovate to lanceolate-ovate, pale green, 2–2.5 mm long, apex acuminate or acute, with green 1-veined costa. Perigynia ovoid or broadly ovoid,
plano-convex, pale yellowish green, longer than pistillate scales, 2.3–2.5 mm long, membranous, glabrous, narrowly winged and serrulate on upper margins, veinless or 1- or 2-veined abaxially, base cuneate, apex abruptly contracted into a 0.2–0.4 mm long beak, beak margins scabrous, orifice 2-lobed with short teeth. Achenes tightly enveloped, ellipsoid or ellipsoid-obovoid, plano-convex, 1.3–1.5 mm long, base shortly stipitate; style thickened at base; stigmas 2. [details]
