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 limosa is a species of sedge known as bog-sedge, mud sedge, and shore sedge.
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 amplifolia is a species of sedge known by the common name bigleaf sedge. It is native to western North America from British Columbia to Montana to California, where it grows in wet and seasonally wet areas in coniferous forests.
Carex cusickii is a species of sedge known by the common name Cusick's sedge. It is native to Northwestern North America from British Columbia to California, and in Utah, where it can be found in several types of wet habitat, such as marshes, mountain meadows, and ditches. In its range it is most common in the Cascade Range and areas west.
Carex diandra is a species of sedge known by the common names lesser tussock-sedge and lesser panicled sedge.
Carex geyeri is a species of sedge known by the common names Geyer's sedge and elk sedge. It is native to western North America from British Columbia to California to Colorado, where it grows in dry areas in mountain meadows, grasslands, and open forest. This sedge produces scattered tufts of stems connected by a network of long rhizomes. The stems are triangular in cross-section and approach half a meter in maximum height. The inflorescence is composed of a cluster of staminate flowers and a cluster of pistillate flowers separated by a node.
Carex luzulina is a species of sedge known by the common name woodrush sedge.
Carex rossii, commonly known as Ross's sedge, is a hardy species of sedge that is often a pioneer species in areas with little or no established vegetation, or in places where disturbance has occurred. Ross's sedge grows in a variety of habitats throughout much of western North America, from Alaska to Ontario, south to New Mexico and California. It flowers in May and June.
Carex vesicaria is an essentially Holarctic species of sedge known as bladder sedge, inflated sedge, and blister sedge. It has been used to insulate footwear in Norway and among the Sami people, and for basketry in North America.
Carex vulpinoidea is a species of sedge known as fox sedge and American fox-sedge. It is native to North America, including most of Canada, the Dominican Republic, the United States and parts of Mexico. It is known in Europe and New Zealand as an introduced species. The sedge lives in wet and seasonally wet habitat, and grows easily as a roadside weed. It produces clumps of stems up to a meter tall. The inflorescence is a dense, tangled cluster of many flower spikes up to about 10 cm (3.9 in) long. Tolerates fluctuating water levels and periods of drying.
Schoenoplectus pungens is a species of flowering plant in the sedge family known as common threesquare, common three-square bulrush and sharp club-rush. It is a herbaceous emergent plant that is widespread across much of North and South America as well as Europe, New Zealand and Australia.
Carex disticha is a Eurasian species of sedge known as the brown sedge or, in North America, tworank sedge.
Carex hirta, the hairy sedge or hammer sedge, is a species of sedge native across Europe. It has characteristic hairy leaves and inflorescences, and is the type species of the genus Carex.
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 spicata is a species of sedge in the genus Carex.
Carex bigelowii is a species of sedge known by the common names Bigelow's sedge, Gwanmo sedge, and stiff sedge. It has an Arctic–alpine distribution in Eurasia and North America, and grows up to 50 centimetres (20 in) tall in a variety of habitats.
Carex saxatilis is a species of sedge known by the common names rock sedge and russet sedge.
Carex divisa is a species of sedge known by the common names divided sedge and separated sedge. It is native to Europe, Asia, and North Africa, and considered naturalized in Australia, New Zealand, and scattered locations in North America.
Carex paniculata, the greater tussock-sedge, is a species of flowering plant in the sedge family, Cyperaceae. It grows 1.5 metres high and can be found in most of Europe, Northwest Asia and North America.
