The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
Carex is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges. Other members of the family Cyperaceae are also called sedges, however those of genus Carex may be called true sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology.
Carex binervis, the green-ribbed sedge, is a European species of sedge with an Atlantic distribution. It is found from Fennoscandia to the Iberian Peninsula, and occurs in heaths, moorland and other damp, acidic environments. It typically grows to a height of 15–120 cm (6–50 in), and has inflorescences comprising one male and several female spikes, each up to 45 mm (1.8 in) long. The utricles have two conspicuous green veins, which give rise to both the scientific name and the common name of the species. In the vegetative state, it closely resembles C. bigelowii, a species that usually grows at higher altitude. C. binervis was first described by James Edward Smith in 1800, and is classified in Carex sect. Spirostachyae; several hybrids with other Carex species are known.
Carex lanceolata is a species of sedge, native to the eastern half of China, Mongolia, eastern Siberia, Korea, Sakhalin, and Japan. Its seeds are dispersed by ants.

Carex annectens, sometimes called yellow-fruited fox sedge, is a species of sedge native to most of the eastern United States and southeastern Canada. It is common in prairies and high-water table fallow fields. In the Chicago area, its coefficient of conservatism is 3, and in Michigan, it is only 1, indicating its relatively low fidelity to high quality habitats.
Carex crinita, called fringed sedge, is a species of flowering plant in the genus Carex, native to central and eastern Canada and the central and eastern United States. It is the namesake of the Carex crinita species complex.
Carex stipata, variously called the prickly sedge, awl-fruited sedge, awlfruit sedge, owlfruit sedge, swamp sedge, sawbeak sedge, stalk-grain sedge and common fox sedge, is a species of flowering plant in the genus Carex, native to Canada, the United States, China, Korea, Japan, and Far Eastern Russia. It is a wetland obligate.
Carex breviculmis, called the Asian shortstem sedge, is a species of flowering plant in the genus Carex, native to Asia from the Indian subcontinent to Southeast Asia, China, Taiwan, Korea, Japan, north as far as Khabarovsk Krai, and Malesia, New Guinea, Australia, Norfolk Island and New Zealand. It has been introduced to the US state of Mississippi. Typically found in forests, it is quite shade tolerant.
Carex muehlenbergii is a species of flowering plant, it is a type of sedge. It is a grass-like plant in the family Cyperaceae. Its common names include sand sedge, Muhlenberg's sedge.
Carex trisperma, the three-seeded sedge, is a species of flowering plant in the genus Carex, native to Canada, Greenland, and the northeastern United States. It is typically found in acidic bogs within forests.
Carex tribuloides, the blunt broom sedge, is a species of flowering plant in the genus Carex, native to the eastern United States, eastern Canada, and Veracruz in Mexico, and introduced in Sweden. It is an important food for soras during their spring migration.
Carex tristachya, called the shiny-spike sedge, is a species of flowering plant in the genus Carex, native to south-central and southeast China, Korea, Japan, the Ryukyus, the Philippines, Borneo, and New Guinea. Its seeds are dispersed by ants.
Carex communis, the fibrous-root sedge, is a species of flowering plant in the genus Carex, native to central and eastern Canada and the central and eastern United States. Its seeds are dispersed by ants.
Carex laxiculmis, the creeping sedge, is a species of flowering plant in the family Cyperaceae, native to Ontario, Canada, and the central and eastern United States. As with most species of sedge, it prefers to grow in shady, wet areas. Its cultivar 'Hobb', sold under the trade designation Bunny Blue, is available from commercial nurseries.
Carex deweyanaDewey's sedge, short-scale sedge, is a species of sedge native to Canada and the United States.
Carex michauxiana, also known as Michaux's sedge, carex de Michaux or yellowish sedge in Canada, is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to eastern parts of North America and parts of Asia.
