Juncus Triglumis
''Juncus triglumis'', called the three-flowered rush, is a species of flowering plant in the genus ''Juncus'', native to the subarctic and subalpine Northern Hemisphere. It is typically found in calcareous tundra habitats and arcto-alpine fens. It is often found in association with ''Carex atrofusca'' and ''Carex bicolor ''Carex bicolor'', the bicoloured sedge, is a species of Cyperaceae, sedge native to North America, Northern Europe and Northern Asia.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncus
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduced t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carex Atrofusca
Carex atrofusca, the dark brown sedge or scorched alpine sedge, is a species of sedge with a circumpolar or circumboreal distribution in the northern hemisphere. Description Carex atrofusca is a perennial cespitose loosely tufted sedge approximately 6–30 cm high. Sheaths present and persisting, brown - yellowish brown. Leaves are 3–4 mm in with approximately half as long as flowering stems. It is monoecious Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is conne ..., with 2-4 spikes, top most one male and 1-3 female spikes nodding.

Carex Bicolor
''Carex bicolor'', the bicoloured sedge, is a species of Cyperaceae, sedge native to North America, Northern Europe and Northern Asia. The International Union for Conservation of Nature has assessed the plant's conservation status as being of Least-concern species, least concern because it has a widespread distribution and faces no particular threats. Description ''Carex bicolor'' is a tufted perennial sedge growing to a height of about . The grass-like leaves are mostly basal, greyish-green with blades up to long and wide, linear, strongly keeled, with parallel veins and long pointed tips. The inflorescence has a triangular stem about the same length as the leaves. It bears two or three spikes of small flowers, the terminal spike having staminate flowers for the lowest third and pistillate flowers above. The floral scale is shorter than the perigynium that surrounds the achene and has brown or reddish-black edges with a green midvein. Distribution and habitat ''Carex bicolor'' ...

Taxa Named By Carl Linnaeus
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
