Pedicularis Dasyantha
''Pedicularis dasyantha'', the woolly lousewort or arctic hairy lousewort, is a plant native to the high arctic areas of Svalbard, Novaya Zemlya and the bordering mainland, and the western Taymyr Peninsula. In Svalbard it is restricted to the main island, Spitsbergen. It grows to 10–15 cm tall, with a stout stem, single or a few together, from a thick, yellow taproot. The basal leaves are numerous and pinnately divided into many remote segments. The stem has many leaves, woolly in the uppermost part between the flowers. The flowers are produced in a dense oblong inflorescence, each flower with a red corolla, with the upper tip hairy; the corolla tube is longer than the calyx. It grows in moist places and on heaths, often together with ''Dryas octopetala'' and ''Cassiope tetragona''. Like all ''Pedicularis'' it is a hemiparasite A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of ang ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Flora Of Siberia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Norway
Norway is a country located in Northern Europe in the northern and western parts of the Scandinavian Peninsula. The majority of the country borders water, including the Skagerrak inlet to the south, the North Sea to the southwest, the North Atlantic Ocean (Norwegian Sea) to the west, and the Barents Sea to the north. It has a land border with Sweden to the east and a shorter border with Finland and an even shorter border with Russia to the northeast. Norway has an elongated shape, one of the longest and most rugged coastlines in the world, and some 50,000 islands off its much-indented coastline. It is one of the world's northernmost countries, and it is one of Europe's most mountainous countries, with large areas dominated by the Scandinavian Mountains. The country's average elevation is , and 32 percent of the mainland is located above the tree line. Its country-length chain of peaks is geologically continuous with the mountains of Scotland, Ireland, and, after crossing under th ...

Pedicularis
''Pedicularis'' is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae (the genus previously having been placed in Scrophulariaceae ''sensu lato''). Description Between 350 and 600 species are accepted by different authorities, mostly from the wetter northern temperate zones, as well as from South America. The highest diversity is in eastern Asia, with 352 species accepted in China alone. Taxonomy The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in livestock. The genus name ''Pedicularis'' is from the Latin ''pediculus'' meaning louse. Selected species *''Pedicularis acaulis'' *''Pedicularis amoena'' *''Pedicularis arguteserrata'' *''Pedicularis ascendens'' *''Pedicularis asparagoides'' *''Pedicularis asplenifolia'' *''Pedicularis attollens'' (little elephant's head) *''Pedicularis baumgartenii'' *''Pedicularis bhutanomuscoide ...

Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassiope Tetragona
''Cassiope tetragona'' (common names include Arctic bell-heather, white Arctic mountain heather and Arctic white heather) is a plant native to the high Arctic and northern Norway, where it is found widely. Growing to 10–20 cm in height, it is a strongly branched dwarf shrub. The leaves are grooved, evergreen, and scale-like in four rows. Pedicels are long and arched. The plant bears bell-shaped, solitary flowers usually with white and pink lobes and pink anthers. The flower stalks and sepals are red, but the petals may also be yellowish-white. The anthers can also be brownish-yellow and flower stalks and sepals yellowish-green. It grows on ridges and heaths, often in abundance and forming a distinctive and attractive plant community. In Greenland, indigenous peoples use the plant as important source of fuel. Because of high resin content, it burns even when wet. The plant can also be used in cooking.

Dryas Octopetala
''Dryas octopetala'', the mountain avens, eightpetal mountain-avens, white dryas or white dryad, is an Arctic–alpine flowering plant in the family Rosaceae. It is a small prostrate evergreen subshrub forming large colonies. The specific epithet ''octopetala'' derives from Greek ''octo'' 'eight' and ''petalon'' 'petal', referring to the eight petals of the flower, an unusual number in the Rosaceae, where five is the normal number. However, flowers with up to 16 petals also occur naturally. As a floral emblem, it is the official territorial flower of the Northwest Territories and the national flower of Iceland. Description The stems are woody, tortuous, with short, horizontal rooting branches. The leaves are glabrous above, densely white-tomentose beneath. The flowers are produced on stalks long, and have eight creamy white petals – hence the specific epithet ''octopetala''. The style is persistent on the fruit with white feathery hairs, functioning as a wind-dispersal agent. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corolla (plant)
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and ''Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alternat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...
