There are over 190 vascular plant species on the Norwegian Arctic archipelago of Svalbard. This figure does not include algae, mosses, and lichens, which are non-vascular plants. For an island so far north, this number of species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm (4 in)
NVC community CG10 is one of the calcicolous grassland communities in the British National Vegetation Classification system. Of the upland group of calcicolous grasslands, it is the only one with a short sward associated with heavy grazing.
The Circumboreal Region in phytogeography is a floristic region within the Holarctic Kingdom in Eurasia and North America, as delineated by such geobotanists as Josias Braun-Blanquet and Armen Takhtajan.
Kenneth Kent Mackenzie (1877–1934) was a lawyer and amateur botanist who wrote extensively on the genus Carex in North America. The standard author abbreviation Mack. is used to indicate this person as the author when citing a botanical name.
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.
Salix hastata is a species of flowering plant in the willow family, known by the common name halberd willow. It has an almost circumpolar distribution, occurring throughout the northern latitudes of the Northern Hemisphere, most frequently found near the coast of the Arctic Ocean. In Alaska, it occurs in the north and in the central mountains. It also occurs in northwestern Canada, and in Norway and Russia, as well as various alpine or mountainous areas of Eurasia.
Carex morrowii, the kan suge, Morrow's sedge, Japanese grass sedge or Japanese sedge, is a species of flowering plant in the family Cyperaceae. It is native to central and southern Japan, and has been introduced to Belgium, Denmark and Austria.
Carex swanii, known as Swan's sedge or downy green sedge, is a species of flowering plant in the family Cyperaceae. It is native to eastern North America.
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 caryophyllea is a species of plant in the family Cyperaceae first described by Marc Antoine Louis Claret de La Tourrette. Two varieties are listed in the World Checklist of Selected Plant Families:
Carex aphyllopus is a species of sedge. Its native range is Central Japan.
The Kalaallit Nunaat high arctic tundra ecoregion covers the coastal areas of northern and eastern Greenland. Areas inland of this strip of land are either covered in ice or bare rock. About one-third of the region is covered by mosses and lichens, and another 3% by herbaceous vegetation and shrubs. The largest national park in the world, Northeast Greenland National Park, protects a majority of the land within the ecoregion.
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 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 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 punctata, the dotted sedge, is a species of flowering plant in the genus Carex, native to Macaronesia, northwest Africa, southern, central, and northern Europe, and Turkey. Its chromosome number is 2n=68.
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 krausei, commonly known as Krause's sedge or carex de Krause in Canada, is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to subarctic areas of Greenland, Alaska, northern Canada and Russia.
