Saxifraga Nathorstii
''Saxifraga nathorstii'', Nathorst's saxifrage, is a species of flowering plant belonging to the family Saxifragaceae. ''Saxifraga nathorstii'' is a putative allotetraploid hydrid between ''S. aizoides'' and ''S. oppositifolia'', and morphologically intermediate, even in terms of pollen, between the parent species. It is native and endemic to Greenland, and has a limited distribution in Northeast Greenland. Description It is a somewhat densely tufted perennial with 3 – 6 cm high ascending stems. The singular sordid pink to fleshy coloured flowers are 8 – 15 mm wide, have 5 petals, which do not overlap, and 5 sepals 2 – 3 mm long. Stems with alternate to opposite 4 – 9 mm long lance-shaped leaves with a pointed oval apex. Distribution and habitat Commonly found on moist sandy to gravelly soils, e.g. in riverbeds sand and gravel or desiccated ponds. Distribution ranges from Danmarks Island (70°30'N) to Jonsbu, Hochstetter Foreland Queen Marg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxifragaceae
Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus ''Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are herbaceous perennials (rarely annual or biennial), sometimes succulent or xerophytic, often with perennating rhizomes. The leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence stems. They are usually simple, rarely pinnately or palmately compound. Their margins may be entire, deeply lobed, cleft, crenate or dentate and petiolate with stipules. The inflorescences are b ...

Saxifraga Aizoides
''Saxifraga aizoides'', yellow mountain saxifrage or yellow saxifrage, is a flowering alpine plant of the genus ''Saxifraga''. Description ''Saxifraga aizoides'' is an evergreen perennial which branches at or below ground level, and grows to . It spreads by short rhizomes, forming mats of small colonies. The flowers, with five sepals and petals, are yellow—green. Distribution It prefers cold and moist well-draining neutral to basic bedrock, gravel, sand, or shale cliff environments. It is found in: North America, including Alaska, across Canada, the Great Lakes region, and Greenland; and in Europe, including the Tatra Mountains, Alps, and Svalbard.

Saxifraga Oppositifolia
''Saxifraga oppositifolia'', the purple saxifrage or purple mountain saxifrage, is a species of plant that is very common in the high Arctic and also some high mountainous areas further south, including northern Great Britain, Britain, the Alps and the Rocky Mountains. ''Saxifraga oppositifolia'' grows at a latitude of 83°40'N on Kaffeklubben Island, making it one of the northernmost plants in the world. Description ''Saxifraga oppositifolia'' is a low-growing, densely or loosely matted plant growing up to high, with somewhat woody branches of creeping or trailing habit close to the surface. The leaves are small, rounded, scale-like, opposite in four rows with ciliated margins. The flowers are solitary on short stalks, petals purple or lilac, much longer than the Calyx (botany), calyx lobes. It is one of the first spring flowers, continuing to flower during the whole summer in localities where the snow melts later. The flowers grow to about in diameter. Ecology Habitat ''S ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Danmark Island
Danmark Island ( kl, Ujuaakajiip Nunaa; da, Danmark Ø) is an island in Scoresby Sund. Administratively it lies in the area of Sermersooq municipality. History The island was named in 1891 by Carl Ryder during his 1891–92 East Greenland Expedition. It was chosen as a wintering harbor in 1891/2 during the exploration of the Scoresby Sund fjord system. Numerous remains of Inuit habitations were found on the island by the East Greenland Expedition, indicating that the Scoresby Sound area had been inhabited in relatively recent times.Spencer Apollonio: ''Lands that Hold One Spellbound.'' University of Calgary Press, 2008, , p. 78 The Greenlandic name ''Ujuaakajiip Nunaa'' was registered in 1955 by the Danish Geodætisk Institut. It means "Little Johan’s Land" after Johan Petersen, Scoresbysund colony manager, who was known to the locals as "Ujuât". Geography Danmark Island lies at the eastern end of Fon Fjord by its mouth. Ten kilometers before the mouth, the fjord has a bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonsbu
Jonsbu was a Norwegian hunting and radio station (Jonsbu Radio/LMW) located on the coast of Eastern Greenland in present-day King Christian X Land. Administratively the area where the hut stood belongs now to the Northeast Greenland National Park. The site is located in southern Hochstetter Foreland on the western side of Peters Bay, northeast of the mouth of Ardencaple Fjord, about from Cape Klinkerfues.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute'', p. 124 History The station was built in 1932 by John Giæver's expedition, about northeast of the mouth of Ardencaple Fjord.

Saxifraga
''Saxifraga'' is the largest genus in the family Saxifragaceae, containing about 465 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word ''saxifraga'' means literally "stone-breaker", from Latin ' ("rock" or "stone") + ' ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney or bladder stones), rather than breaking rocks apart. Description Most saxifrages are small perennial, biennial (e.g. '' S. adscendens'') or annual (e.g. '' S. tridactylites'') herbaceous plants whose basal or cauline leaves grow close to the ground, often in a rosette. The leaves typically have a more or less incised margin; they may be succulent, needle-like and/or hairy, reducing evaporation. The inflorescence or single flower clusters rise above the main plant body on naked stalks. The small actinomorphic hermaphrodite flowers have five petals and sepals and are usually white, but red to yellow in some specie ...
