Discaria Americana
''Discaria'' is a genus of 6 species of flowering plants in the family Rhamnaceae, native to temperate regions of the Southern Hemisphere, in Australia, New Zealand and South America. They are deciduous thorny shrubs or small trees growing to 2–5 m tall. They are also non-legume nitrogen fixers. Many of the world's ''Discaria'' species qualify as xerophytes in the true sense of the term, and the Australian species are no exception. They frequently occur on porous or well-drained sites and on soils of low fertility. Some species can fix nitrogen from the atmosphere with the help of symbiotic bacteria (''Frankia'') that form nodules in their roots. Taxonomy Species ''Discaria'' comprises the following species: * '' Discaria americana'' Gillies & Hook. * '' Discaria articulata'' (Phil.) Miers * '' Discaria chacaye'' (G.Don) Tortosa * '' Discaria nitida'' Tortosa * ''Discaria pubescens ''Discaria pubescens'', the hairy anchor plant or Australian anchor plan ...

Nitrogen
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discaria toumatou
''Discaria toumatou'', commonly called matagouri, tūmatakuru, or wild Irishman, is a tangle-branched thorny shrub endemic to New Zealand. It is common throughout the South Island and is less common in the North Island. Taxonomy This species was described by French naturalist Étienne Raoul in 1844 from material collected in Akaroa in association with '' Pteridium esculentum''. The generic name ''Discaria'' refers to disc-shaped flowers. The Latinised specific epithet Raoul chose, ''toumatou'', is a corruption of the word ''tūmatakuru'', one of the Māori names for this species, which he transcribed as "toumatou-kourou". Etymology The English name ''matagouri'' is another corruption of ''tūmatakuru''. Other names in the Māori language include ''tūmatakuri'' and ''tūturi''. Another name is "wild Irishman"; the English writer Samuel Butler in 1863 recalled "…a very uncomfortable prickly shrub, which they call Irishman, and which I do not like the look of at all." D ...

Missouri Botanical Garden
The Missouri Botanical Garden is a botanical garden located at 4344 Shaw Boulevard in St. Louis, Missouri. It is also known informally as Shaw's Garden for founder and philanthropy, philanthropist Henry Shaw (philanthropist), Henry Shaw. Its herbarium, with more than 6.6 million specimens, is the second largest in North America, behind that of the New York Botanical Garden. Its Peter H. Raven Library contains 85% coverage of all literature ever published on systematic botany and plant taxonomy. The ''Index Herbariorum'' code assigned to the herbarium is MO and it is used when citing housed specimens. History The land that is currently the Missouri Botanical Garden was previously the land of businessman Henry Shaw. Founded in 1859, the Missouri Botanical Garden is one of the oldest botanical institutions in the United States and a National Historic Landmark. It is also listed in the National Register of Historic Places. In 1983, the botanical garden was added as the fourt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries. Kew, jointly with the Forestry Commission, founded Bedgebury National Pinetum in Kent in 1923, specialising in growing conifers. In 1994, the Castle Howard Arboretum Trust, which runs the Yorkshire Arboretum, was formed as a partnership between Kew and the Castle Howard Estate. In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst. Its site ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Plant List
The Plant List was a list of botanical names of species of plants created by the Royal Botanic Gardens, Kew and the Missouri Botanical Garden and launched in 2010. It was intended to be a comprehensive record of all known names of plant species over time, and was produced in response to Target 1 of the 2002–2010 Global Strategy for Plant Conservation (GSP C), to produce "An online flora of all known plants". It has not been updated since 2013, and has been superseded by World Flora Online. World Flora Online In October 2012, the follow-up project World Flora Online was launched with the aim to publish an online flora of all known plants by 2020. This is a project of the United Nations Convention on Biological Diversity, with the aim of halting the loss of plant species worldwide by 2020. It is developed by a collaborative group of institutions around the world response to the 2011-2020 GSPC's updated Target 1. This aims to achieve an online Flora of all known plants by 2020 ...

Frankia
''Frankia'' is a genus of nitrogen-fixing bacteria that live in symbiosis with actinorhizal plants, similar to the '' Rhizobium'' bacteria found in the root nodules of legumes in the family Fabaceae. ''Frankia'' also initiate the forming of root nodules. This genus was originally named by Jørgen Brunchorst, in 1886 to honor the German biologist Albert Bernhard Frank. Brunchorst considered the organism he had identified to be a filamentous fungus. redefined the genus in 1970 as containing prokaryotic actinomycetes and created the family Frankiaceae within the Actinomycetales. He retained the original name of ''Frankia'' for the genus. __TOC__ Overview Most ''Frankia'' strains are specific to different plant species. The bacteria are filamentous and convert atmospheric nitrogen into ammonia via the enzyme nitrogenase, a process known as nitrogen fixation. They do this while living in root nodules on actinorhizal plants. The bacteria can supply most or all of the nit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
