Subgen. Carex: Monoecious; spikes 2 or more, usually unisexual and ± dissimilar, terminal or upper male and lower lateral female, or sometimes terminal gynecandrous and similar to lateral female; inflorescence usually simple; cladoprophyll usually present; stigmas 2 or 3; nut trigonous to terete or biconvex to plano-convex.
Sect. Phacocystis: Caespitose or not, with or without creeping rhizomes. Male spikes 1 to several, 1 in terminal position (or terminal spike gynecandrous); female spikes few to several, ± cylindrical, usually dense, long-pedunculate to sessile, erect to pendent; lowest bract leaf-like, sheathless. Utric1es plano- to biconvex, membranous, inflated, glabrous; beak very short, truncate to emarginate. Stigmas 2. Nut lenticular.
Caespitose to laxly tufted with long, stout rhizomes covered with brownish scales. Stems (30-)50-120(-150) cm, sharply trigonous, scabrid at least above, erect or slight1y nodding above; basal sheaths usually with lamina, not keeled, pale yellowish-brown to dark red-brown, dull, usually transversely septate, margins entire, older remnants not fibrous. Leaves 4-10 mm broad, equalling stems or longer, rather dark green, plicate, margins revolute when dry, minutely papillose beneath, scabrid at margins and on main veins. Male spikes (1-)2-4, usually aggregated, 20-50 mm, narrowly cylindrical. Female spikes 2-5(-7), overlapping or lowest somewhat distant, 30-110 mm, cylindrical, subsessile or lowest shortly pedunculate, erect or often nodding; lowest bract often as broad as leaves, equalling or often longer than inflorescence. Female glumes ovate oblong to lanceo1ate, narrower and shorter or longer than utricles, obtuse to acute or sometimes acuminate; mid-vein usually distinct, ± greenish. Utricles green at first, later pale brownish-green, often somewhat purplish above, elliptic to broadly ovate, 2-3.5 mm, biconvex, papillose above, sometimes shortly stipitate, veins usually s1ender but distinct; beak short but distinct, to 0.5 mm, ± truncate. Margins of lakes and streams, sometimes in shallow water, wet meadows, often forming pure stands, 10-2450 m. IX:151.
