Epipactis Youngiana
''Epipactis helleborine'' var. ''youngiana'', known as Young's helleborine, is a variety of orchid that is endemic to Great Britain. It has also been treated as a separate species, ''Epipactis youngiana''. Taxonomy ''Epipactis helleborine'' var. ''youngiana'' was discovered in 1975 by Tony Porter, and described as a new species by Porter and A. J. Richards in 1982. The specific epithet commemorates Donald Peter Young, who worked extensively on ''Epipactis''. It is part of the ''Epipactis helleborine'' species complex, and cannot be distinguished from the wide-ranging and variable species ''E. helleborine'' using genetic markers. It is therefore treated as a variety of the widespread species, as ''E. helleborine'' var. ''youngiana''. ''Epipactis helleborine'' var. ''youngiana'' was thought to be a hybrid between two other orchid taxa, probably '' E. dunensis'' and ''E. helleborine''. More recently it is treated simply as a variety of ''E. helleborine''. ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...

Anther
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in '' Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of The United Kingdom
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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epipactis
''Epipactis'', or helleborine, is a genus of terrestrial orchids consisting of approximately 70 species. This genus is abbreviated as Epcts in horticultural trade. Description Their creeping, fleshy rhizomes grow offshoots, from which then emerge the 20–70 cm long stems during the next spring. There are four to eight alternate, lanceolate leaves, that grow progressively shorter near the top. The margins are entire, the top is acute. Species with less chlorophyll have blue-purple leaves. Their bilaterally symmetrical colorful flowers grow from a terminal raceme. The three sepals and the two lateral petals are ovate and acuminate. Their color can vary from greenish-white to violet and purple. The lip is divided in a bowl-shaped hypochile, with the outer surface greenish-white and threaded with dark veins. The wavy, snow-white epichile is fan-shaped. The ovary is inferior. It produces a dry capsule with countless minute seeds. Chemistry As is characteristic of all orch ...

Wildlife And Countryside Act 1981
The Wildlife and Countryside Act 1981 is an Act of Parliament in the United Kingdom implemented to comply with European Council Directive 79/409/EEC on the conservation of wild birds. In short, the act gives protection to native species (especially those at threat), controls the release of non-native species, enhances the protection of Sites of Special Scientific Interest and builds upon the rights of way rules in the National Parks and Access to the Countryside Act 1949. The Act is split into 4 parts covering 74 sections; it also includes 17 schedules. The legislation has strength; few amendments have been made to it, and it has acted as a foundation for later legislation to build upon. The compulsory 5 year review of schedules 5 and 8 make it dynamic in terms of the species which it protects. History Wild Birds Protection Act 1902 The Wild Birds Protection Act 1902 ( 2 Edw 7 c. 6) was an Act of Parliament of the Parliament of the United Kingdom, given the royal assent on 2 ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Talbot Steelworks
Port Talbot Steelworks is an integrated steel production plant in Port Talbot, West Glamorgan, Wales, capable of producing nearly 5 million tonnes of steel slab per annum. This makes it the larger of the two major steel plants in the UK and one of the largest in Europe. Over 4,000 people work at the plant. The majority of the slab is rolled on-site at Port Talbot and at the Newport Llanwern site to make a variety of steel strip products. The remainder is processed at other Tata Steel plants or sold in slab form. The works covers a large area of land which dominates the south of the town. Its two blast furnaces and steel production plant buildings are major landmarks visible from both the M4 motorway and the South Wales Main Line when passing through the town. History The site at Margam is made up of a number of plants across a large site, developed since 1901. Port Talbot works The original works were built by Gilbertson, and situated south of Port Talbot railway station. Cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sand Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented san ...

Central Belt
The Central Belt of Scotland is the area of highest population density within Scotland. Depending on the definition used, it has a population of between 2.4 and 4.2 million (the country's total was around 5.4 million in 2019), including Greater Glasgow, Ayrshire, Falkirk, Edinburgh, Lothian and Fife. Despite the name, it is not geographically central but is nevertheless at the "waist" of Scotland on a conventional map and the term "central" is used in many local government, police and NGO designations. It was formerly known as the Midlands or Scottish Midlands but this term has fallen out of fashion. The Central Belt lies between the Highlands to the north and the Southern Uplands to the south. In the early 21st century, predictions were made that due to economic migration indicators, the urban areas of Glasgow and Edinburgh, whose centres are approximately apart, could merge to create a megalopolis over the coming decades.

River South Tyne
The River Tyne is a river in North East England. Its length (excluding tributaries) is . It is formed by the North Tyne and the South Tyne, which converge at Warden Rock near Hexham in Northumberland at a place dubbed 'The Meeting of the Waters'. The Tyne Rivers Trust measure the whole Tyne catchment as , containing of waterways. Course North Tyne The North Tyne rises on the Scottish border, north of Kielder Water. It flows through Kielder Forest, and in and out of the border. It then passes through the village of Bellingham before reaching Hexham. South Tyne The South Tyne rises on Alston Moor, Cumbria and flows through the towns of Haltwhistle and Haydon Bridge, in a valley often called the Tyne Gap. Hadrian's Wall lies to the north of the Tyne Gap. Coincidentally, the source of the South Tyne is very close to those of the Tees and the Wear. The South Tyne Valley falls within the North Pennines Area of Outstanding Natural Beauty (AONB) – the second largest of th ...
