Argentina Anserina
''Argentina anserina'' (synonym ''Potentilla anserina'') is a perennial flowering plant in the rose family, Rosaceae. It is known by the common names silverweed, common silverweed or silver cinquefoil. It is native throughout the temperate Northern Hemisphere, often on river shores and in grassy habitats such as meadows and road-sides. The plant was originally placed in the genus ''Potentilla'' by Carl Linnaeus in his Species plantarum, edition 1, (1753) but was reclassified into the resurrected genus ''Argentina'' by research conducted in the 1990s. The reclassification remains controversial and is not accepted by some authorities. It is a species aggregate which has frequently been divided into multiple species. Description Silverweed is a low-growing herbaceous plant with creeping red stolons that can be up to 80 cm long. The leaves are 10–20 cm long, evenly pinnate into in saw-toothed leaflets 2–5 cm long and 1–2 cm broad with 6 - 14 teeth per side, ...

John Hill (author)
Sir John Hill was an English composer, actor, author and botanist. He contributed to contemporary periodicals and engaged in literary battles with poets, playwrights and scientists. He is remembered for his illustrated botanical compendium ''The Vegetable System'', one of the first works to use the nomenclature of Carl Linnaeus. In recognition of his efforts, he was created a knight of the Order of Vasa in 1774 by Gustav III of Sweden and thereafter called himself Sir John Hill. Biography He was the son of the Rev. Theophilus Hill and is said to have been born in Peterborough. He was apprenticed to an apothecary and on the completion of his apprenticeship he set up in a small shop in St Martin's Lane, Westminster. He also travelled over the country in search of rare herbs, with a view to publishing a ''hortus siccus'', but the plan failed. He obtained the degree of M.D. from the University of St. Andrews at a time when its fortunes were at a low ebb, and practised as a quack ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Rose
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' comes from L ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Rosaceae
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are ''Alchemilla'' (270), ''Sorbus'' (260), '' Crataegus'' (260), ''Cotoneaster'' (260), ''Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potentilla
''Potentilla'' is a genus containing over 300Guillén, A., et al. (2005)Reproductive biology of the Iberian species of ''Potentilla'' L. (Rosaceae).''Anales del JardÃn Botánico de Madrid'' 1(62) 9–21. species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae. Potentillas may also be called cinquefoils in English, but they have also been called five fingers and silverweeds. Some species are called tormentils, though this is often used specifically for common tormentil (''P. erecta''). Others are referred to as barren strawberries, which may also refer to '' P. sterilis'' in particular, or to the closely related ''Waldsteinia fragarioides''. Several other cinquefoils formerly included here are now separated in distinct genera - notably the popular garden shrub ''P. fruticosa'', now ''Dasiphora fruticosa''. Potentillas are generally found throughout the northern continents of the world (holarctic), though some occur in montane biomes of ...

Argentina Anserinoides
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human presenc ...

Argentina Egedei
''Argentina egedei'', known as Eged's silverweed, is a flowering perennial plant in the rose family, Rosaceae. It is a salt-tolerant plant native to arctic and cool temperate coasts of the Northern Hemisphere, most commonly growing in salt marshes. The southern limits of the range are California and Long Island, New York in North America, and the Baltic Sea and coastal eastern Siberia in Eurasia. It is also sometimes called "Pacific silverweed", though this usually refers to '' Argentina pacifica'' and in any case does not describe the range of Eged's Silverweed well. It was formerly classified in the genus ''Potentilla'' as ''Potentilla egedei''. It is considered a member of the ''Argentina anserina'' species aggregate, or is alternatively treated as a subspecies of ''A. anserina'' by some botanists. Eged's Silverweed is a low-growing herbaceous plant with creeping red stolons up to 80 cm long. The leaves are 10–40 cm long, evenly pinnate into in crenate leaflets 3†...

Argentina Pacifica
''Argentina pacifica'', sometimes called pacific silverweed, silverweed cinquefoil, or simply silverweed, is a low-growing perennial (6") with pinnately compound green leaves with silvery undersides. It is a member of the species aggregate known as ''Argentina anserina'' or ''Potentilla anserina''. The yellow, saucer-shaped flowers appear late spring through summer. Pacific silverweed spreads very quickly in moist areas. Preferring salt marshes, river estuaries and shorelines, they are often seen growing alongside springbank clover. They need sun and regular water. Pacific silverweed is important in Pacific Northwest coastal indigenous cultures. Indigenous people dig for its edible roots. As an important vegetable, families maintained rights to access patches through potlatch law. New plants can grow from small root fragments, and with some attention families could guarantee patches persisted for generations "over hundreds, even thousands of years". Northwest Coast peoples used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
