Carex flacca, with common names blue sedge, gray carex, glaucous sedge, or carnation-grass,, is a species of sedge native to parts of Europe and North Africa. It is frequent in a range of habitats, including grasslands, moorlands, exposed and disturbed soil, and the upper edges of salt marshes. It has naturalized in eastern North America.
Carex pendula is a large sedge of the genus Carex. It occurs in woodland, scrubland, hedges and beside streams, preferring damp, heavy clay soils. It is sometimes grown as a garden plant because of its distinctive appearance.
Carex abrupta is a species of sedge known by the common name abrupt-beaked sedge or abruptbeak sedge. It is native to the western United States from California to Idaho, where it grows in moist mountain habitat such as meadows.
Carex helleri is a species of sedge known by the common name Heller's sedge. It is native to eastern California and western Nevada, where it grows on rocky mountain slopes and in other habitats.
Carex nigricans is a species of sedge known by the common name black alpine sedge.
Carex klamathensis is a rare species of sedge known by the common name Klamath sedge. It is known from 15 or fewer populations in southern Oregon and three populations in the Klamath Region of northern California. It was described to science only in 2007. Its habitat includes fens and other wet habitat, on serpentine soils.
Carex lutea is a rare species of sedge known by the common names golden sedge and sulphur sedge. It is endemic to North Carolina, where it is known only from Pender and Onslow Counties in the Cape Fear River watershed. There are nine populations. The plant was discovered in 1991 and described to science as a new species in 1994, and it has not been thoroughly studied nor completely surveyed yet. Its rarity was obvious by 2002, however, when it was federally listed as an endangered species.
Carex riparia, the greater pond sedge, is a species of sedge found across Europe and Asia. It grows in a variety of wet habitats, and can be a dominant species in some swamps. It is Britain's largest Carex, growing up to 130 cm tall, with glaucous leaves up to 160 cm long. It hybridises with a number of other Carex species, including the closely related Carex acutiformis – the lesser pond sedge. A variegated cultivar is grown as an ornamental grass.
Carex lemmonii, or Lemmon's sedge, is a plant in the sedge family, and is endemic to California. Carex albida is now considered a synonym, but was previously thought to be a separate species; such plants have the common name white sedge.
Carex hirtifolia, the pubescent sedge, is a species of sedge native to north-eastern North America. It is the only species in Carex section Hirtifoliae. The entire plant is distinctively covered soft hairs.
Carex lupuliformis, common name false hop sedge, is a perennial sedge of sporadic distribution found in the floodplain forests and ephemeral woodland ponds of central and eastern North America. The species typically produces four to seven leaves with sheaths of distal leaves of 3 to 21 cm whose ligules are rounded to triangular. Carex lupuliformis blooms between early June and early October, typically with "two to six proximal female spikes, distal spikes usually crowded, ascending, densely flowered, usually cylindric, much longer than broad; one to two terminal male spikes." Fruiting occurs between late July through early October. Fruit is described as "perigynia ascending to spreading, inflated, strongly veined, sessile, lance-ovoid, shiny, glabrous; beak conical; achenes stipitate, broadly diamond-shaped, scarcely if at all longer than wide, concave faces, angles thickened, prominently knobbed with hard, nipplelike points."
Carex sprengelii, known as Sprengel's sedge and long-beaked sedge, is a sedge with hanging seed heads, native to North America.
Carex cherokeensis, commonly called Cherokee sedge, is a species of flowering plant in the sedge family (Cyperaceae). It is native to the United States where it is found in the Southeast. Its natural habitat is in high-nutrient, often calcareous soil, in bottomland forests, mesic forests, and wet meadows.
Carex bromoides, known as brome-like sedge, brome-sedge, and dropseed of the woods, is a species of sedge in the genus Carex. It is native to North America.
