Erythranthe Peregrina
''Erythranthe peregrina'' is a species of monkeyflower. Its Latin name means "foreign", or more loosely "the foreigner". This species is a rare example of polyploidization and speciation where sterility did not occur. It was discovered in 2011, first reported in 2012, and named ''Mimulus peregrinus''. Around the same time, the genus ''Mimulus'' was restructured and this species is now called ''Erythranthe peregrina'' and is in the section ''Simiolus''. The species was less than 140 years old at the time of discovery in 2011; its discoverer, Mario Vallejo-Marin of the University of Stirling, compared finding it to "looking at the big bang in the first milliseconds of its occurrence". Description ''Erythranthe peregrina'' has a high level of pollen and seed fertility. Its vegetative and floral characteristics are intermediate between its two ancestral species, '' E. guttata'' and '' E. lutea''. ''E. peregrina'' is a perennial herb high. The leaves are generally variable, ovate- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs 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 sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), 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 size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''. The stamens in a flower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orkney
Orkney (), also known as the Orkney Islands, is an archipelago off the north coast of mainland Scotland. The plural name the Orkneys is also sometimes used, but locals now consider it outdated.

South Lanarkshire
South Lanarkshire (; ) is one of 32 unitary authorities of Scotland. It borders the south-east of the Glasgow City council area and contains some of Greater Glasgow's suburban towns, as well as many rural towns and villages. It also shares borders with Dumfries and Galloway, East Ayrshire, East Renfrewshire, North Lanarkshire, the Scottish Borders and West Lothian. It includes most of the historic county of Lanarkshire. The administrative centre of South Lanarkshire is Hamilton, with the seat of the local authority, South Lanarkshire Council, located at Lanark County Buildings. History South Lanarkshire covers the southern part of the historic county of Lanarkshire. Lanarkshire had existed as a shire from around the time of King David I, who ruled Scotland from 1124 to 1153. The county took its name from the original county town at Lanark, which had been the site of the first Parliament of Scotland under Kenneth II in 978. Local government was reformed in 1975 under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leadhills
Leadhills, originally settled for the accommodation of miners, is a village in South Lanarkshire, Scotland, WSW of Elvanfoot. The population in 1901 was 835. It was originally known as Waterhead. It is the second highest village in Scotland, the highest being neighbouring Wanlockhead, south. It is near the source of Glengonnar Water, a tributary of the River Clyde. Local attractions Library The Leadhills Miners' Library (also known as the Allan Ramsay (poet), Allan Ramsay Library or the Leadhills Reading Society), founded in 1741 by 21 miners, the local schoolteacher and the local minister, specifically to purchase a collection of books for its members’ mutual improvement — its membership was not restricted to the miners; several non-miners, such as William Symington, John Brown (physician, born 1810), John Brown (author of ''Rab and his Friends'') and James Braid (surgeon), James Braid, were also full members — houses an extensive antiquarian book collection, loca ...

River Tees
The River Tees (), in England, rises on the eastern slope of Cross Fell in the North Pennines and flows eastwards for to reach the North Sea in the North East of England. The modern-day history of the river has been tied with the industries on Teesside in its lower reaches, where it has provided the means of import and export of goods to and from the North East England. The need for water further downstream also meant that reservoirs were built in the extreme upper reaches, such as Cow Green. Etymology The name ''Tees'' is possibly of Brittonic origin. The element ''*tēs'', meaning "warmth" with connotations of "boiling, excitement" ( Welsh ''tes''), may underlie the name. ''*Teihx-s'', a root possibly derived from Brittonic ''*ti'' (Welsh ''tail'', "dung, manure"), has also been used to explain the name ''Tees'' (compare River Tyne). Geography The river drains and has a number of tributaries including the River Greta, River Lune, River Balder, River Leven and ...

Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are visible under a light microscope only during the metaphase of cell division, where all chromosomes are aligned in the center of the cell in their condensed form. Before this stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

Polyploid
Polyploidy is a condition in which the biological cell, cells of an organism have more than two paired sets of (Homologous chromosome, homologous) chromosomes. Most species whose cells have Cell nucleus, nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in pairs of homologous chromosomes. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A Ploidy, monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have Biological life cycle, life cycles with two alternation of generations, alternating multicellular generations. The gamet ...

Sympatric Speciation
Sympatric speciation is the evolution of a new species from a surviving Common descent, ancestral species while both continue to inhabit the same geographic region. In evolutionary biology and biogeography, ''sympatric'' and ''sympatry'' are terms referring to organisms whose Range (biology), ranges overlap so that they occur together at least in some places. If these organisms are closely related (e.g. sister species), such a distribution may be the result of sympatric speciation. Etymologically, sympatry is derived . The term was coined by Edward Bagnall Poulton in 1904, who explains the derivation. Sympatric speciation is one of three traditional geographic modes of speciation.Futuyma, D. J. 2001. ''Evolution'' (2nd edition). Sinauer Associates, Inc. Allopatric speciation is the evolution of species caused by the geographic isolation of two or more populations of a species. In this case, divergence is facilitated by the absence of gene flow. Parapatric speciation is the evolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Etymology 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 (botany), 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'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erythranthe
''Erythranthe'', the monkey-flowers and musk-flowers, is a diverse plant genus with more than 120 members (as of 2022) in the family (biology), family Phrymaceae. ''Erythranthe'' was originally described as a separate genus, then generally regarded as a section within the genus ''Mimulus'', and recently returned to generic rank. ''Mimulus'' sect. ''Diplacus'' was segregated from ''Mimulus'' as a separate genus at the same time. ''Mimulus'' remains as a small genus of eastern North America and the Southern Hemisphere. Molecular data show ''Erythranthe'' and ''Diplacus'' to be distinct evolutionary lines that are distinct from ''Mimulus'' as strictly defined, although this nomenclature is controversial. Member species are usually annual plant, annuals or herbaceous perennial plant, perennials. Flowers are red, pink, or yellow, often in various combinations. A large number of the ''Erythranthe'' species grow in moist to wet soils with some growing even in shallow water. They are not ...
