Carex virescens, the ribbed sedge, is a species of flowering plant in the family Cyperaceae, native to eastern North America. [1] [2] It strongly resembles and has nearly the same range as Carex swanii . [3]
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 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 roanensis is a species of sedge known by the common name Roan Mountain sedge. It is native to North America, where it can be found in the southern Appalachian Mountains. It was first collected on Roan Mountain in Tennessee in 1936. It was not collected again for fifty years. Now it is known from Georgia, Kentucky, North Carolina, Pennsylvania, South Carolina, Tennessee, Virginia, and West Virginia.
Carex aboriginum is a species of sedge endemic to Idaho in the western United States, known as Indian Valley sedge. It was not observed in the wild between 1910, when it was first described, and 1999. Until its rediscovery, C. aboriginum was considered the only plant native to Idaho to have become extinct, and it remains one of the state's rarest and most endangered plant species.
Carex lacustris, known as lake sedge, is a tufted grass-like perennial of the sedge family (Cyperaceae), native to southern Canada and the northern United States. C. lacustris us an herbaceous surface-piercing plant that grows in water up to 50 cm (1.6 ft) deep, and grows 50–150 cm (1.6–4.9 ft) tall. It grows well in marshes and swampy woods of the boreal forest, along river and lake shores, in ditches, marshes, swamps, and other wetland habitat. It grows on muck, sedge peat, wet sand or silt, in filtered or full sunlight.
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 rosea, the rosy sedge, is a flowering plant and part of the family Cyperaceae. Synonyms for Carex rosea include Carex concoluta, and Carex flaccidula. It is native to central and eastern North America and it exists in wet to dry soils. Carex rosea can be found in shores of streams and bottomlands, as well as ponds. It is known to have great adaptations to dry-shade locations. This is an evergreen, easy-to-grow-plant.
Carex juniperorum, the juniper sedge, is a perennial flowering plant native to North America, first described by botanist William J. Crins in 1993. C. juniperorum is in the Cyperaceae (sedge) family, and is closely related to C. jamesii and C. willdenowii. It is commonly called juniper sedge as it is often seen growing in areas with red cedar, though the presence of cedar is not necessarily a requirement for it to grow.
Carex dioica, the dioecious sedge, is a species of flowering plant in the genus Carex, native to Iceland, the Faroes, Svalbard, nearly all of Europe, western Siberia, and the Altai. It prefers to live in calcareous fens.
Carex deweyanaDewey's sedge, short-scale sedge, is a species of sedge native to Canada and the United States.
Carex atlantica, the prickly bog sedge, is a species of flowering plant in the family Cyperaceae, native to eastern North America, and eastern Hispaniola. It is usually found growing in bogs or acidic seeps.
Carex tristis is a species of sedge, native to the Caucasus Mountains and adjoining areas. It is the most abundant plant species found on summits.
Carex caespititia, also known as cong sheng tai cao, is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to parts of Asia from Assam in northern India in the west to central China in the east.
Carex cruenta is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to parts of Asia, from Pakistan in the west to south central parts of China in the east.
Carex haematostoma, also known as hong zui tai cao in China, is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to parts of central Asia and China.
Carex feta, the green-sheathed sedge or greensheath sedge, is a species of flowering plant in the family Cyperaceae, native to southwestern British Columbia in Canada, and Washington, Oregon, and California in the United States. Its chromosome number is n = 33.
Carex raphidocarpa is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to India.
Carex spicigera is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to Sri Lanka.
Carex baltzellii, Baltzell's sedge, is a species of flowering plant in the family Cyperaceae, native to the US states of Mississippi, Alabama, Florida, and Georgia. A rare species, it is found only on the slopes of forested ravines.
