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.
The hybrid elm cultivar Ulmus × hollandica 'Dampieri', one of a number of cultivars arising from the crossing of the Wych Elm U. glabra with a variety of Field Elm U. minor, is believed to have originated in continental Europe. It was marketed in Wetteren, Belgium, in 1851 as 'Orme de Dampier', then in the Low Countries in 1853, and later identified as Ulmus campestris var. nuda subvar. fastigiata DampieriHort., Vilv. by Wesmael (1862).
The elm cultivar Ulmus 'Atropurpurea' [:dark purple] was raised from seed at the Späth nursery in Berlin, Germany, circa 1881, as Ulmus montana atropurpurea, and was marketed there till the 1930s, being later classed as a cultivar by Boom. Henry (1913) included it under Ulmus montana cultivars but noted that it was "very similar to and perhaps identical with" Ulmus purpureaHort. At Kew it was renamed U. glabraHuds. 'Atropurpurea', but Späth used U. montana both for wych elm and for some U. × hollandica hybrids, so his name does not necessarily imply a wych elm cultivar. The Hesse Nursery of Weener, Germany, however, which marketed 'Atropurpurea' in the 1950s, listed it in later years as a form of U. glabraHuds..
The hybrid elm cultivar Ulmus × hollandica 'Tricolor' was first listed as U. suberosa tricolor by C. de Vos in 1867.
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.
The elm cultivar Ulmus 'Fastigiata Glabra' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. montana fastigiata glabra. Späth used U. montana both for cultivars of wych elm and for those of some U. × hollandica hybrids like 'Dampieri'. A specimen of U. montana fastigiata glabra in the Royal Botanic Garden Edinburgh was determined by Melville in 1958 as a hybrid of the U. × hollandica group.
The hybrid elm cultivar Ulmus × hollandica 'Viminalis' [:osier-leaved] was listed by the Späth nursery of Berlin as Ulmus scabraMill. var. viminalis in 1890 and as Ulmus montana viminalis from 1892. Though Späth's catalogues stated that it was "also distributed under the name planera aquatica", it remained in his lists under 'elm' and was accessioned by the Dominion Arboretum, Ottawa, and by the Royal Botanic Garden Edinburgh as an elm cultivar. A similar misidentification occurred in the mid-20th century, when the Siberian elm cultivar Ulmus pumila 'Poort Bulten' was for many years commercially propagated under the name Planera aquatica or 'water elm'. As the leaves of osier or Salix viminalis, however, differ markedly from those of Planera aquatica, being long, thin and tapering at both ends, Spath's name 'Viminalis' for this elm cultivar confirms that its leaves were not Planera-like. The probable explanation for the early distribution name is that Planera was the old name for Zelkova, a close relative of elm with willow-like leaves. It is therefore unlikely that 'Viminalis' was related in any way to the 19th-century elm cultivar Ulmus 'Planeroides'.
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.
Carex careyana, commonly known as Carey's sedge, is a species of sedge found in the eastern United States and Ontario, Canada.
Carex viridula, known as little green sedge, green sedge, or greenish sedge, is a small flowering plant native to North America, Europe, Asia, and Morocco.
Carex vulpina, the true fox sedge, is a species in the genus Carex, native to Europe and western Asia. It is difficult to distinguish it from its close relative Carex otrubae, false fox sedge.
Carex flava, called hedgehog grass, is a widespread species of sedge, native to the northern United States, Canada, Iceland, Europe, the Atlas Mountains in Africa, the Transcaucasus area, and parts of Siberia. It is the namesake of the Carex flava species complex.
Carex pallescens, called pale sedge, is a widespread species of flowering plant in the genus Carex, native to the northeastern United States, eastern Canada, Iceland, Europe, Tunisia, and western Asia. It has unstable chromosome numbers.
Carex atrata, called black alpine sedge, is a widespread species of flowering plant in the genus Carex, native to Greenland, Iceland, and most of Europe, plus scattered locations across temperate Asia, including Anatolia, Siberia and the Himalaya, as far as Taiwan and Japan. Its chromosome number is 2n=52, with some variants reported, e.g. n2=54 for Greenland material.
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 tenuiflora, the sparse-flowered sedge, is a species of flowering plant in the family Cyperaceae. It is native to the Subarctic and Hemiboreal Northern Hemisphere; Alaska, Canada, the northern US, Scandinavia, the Baltic States, all of Russia, the north Caucasus, Siberia, the Russian Far East, Mongolia, northern China, Korea, and Japan. It is most often found in peatlands, preferring a pH of 6.
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 baccans, the crimson-seeded sedge, is a species of flowering plant in the family Cyperaceae, with a widespread distribution in subtropical and tropical Asia; most of the Indian Subcontinent, southern China, most of Malesia, and on to New Guinea. An endophytic bacteria species, Glycomyces endophyticus, has been isolated from its roots.
Carex exsiccata, the western inflated sedge or beaked sedge, is a species of flowering plant in the family Cyperaceae, native to British Columbia, Washington state, Oregon, Idaho, Montana, Colorado, and California. Native peoples used its roots to make a black dye.
