Snake's-head Fritillary
''Fritillaria meleagris'' is a Eurasian species of flowering plant in the lily family Liliaceae. Its common names include snake's head fritillary, snake's head (the original English name), chess flower, frog-cup, guinea-hen flower, guinea flower, leper lily (because its shape resembled the bell once carried by lepers), Lazarus bell, chequered lily, chequered daffodil, drooping tulip or, in the British Isles, simply fritillary. The plant is a bulbous perennial native to the flood river plains of Europe where it grows in abundance. Etymology The Latin specific epithet ''meleagris'' means "spotted like a guineafowl". The common name "snake's head" probably refers to the somewhat snakelike appearance of the nodding flower heads, especially when in bud, on their long stems. Description and habitat The flower has a chequered pattern in shades of purple, or is sometimes pure white. It flowers from March to May and grows between in height. The plant has a button-shaped bulb, about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naturalisation (biology)
Naturalisation (or naturalization) is the ecological phenomenon through which a species, taxon, or population of exotic (as opposed to native) origin integrates into a given ecosystem, becoming capable of reproducing and growing in it, and proceeds to disseminate spontaneously. In some instances, the presence of a species in a given ecosystem is so ancient that it cannot be presupposed whether it is native or introduced. Generally, any introduced species may (in the wild) either go extinct or naturalise in its new environment. Some populations do not sustain themselves reproductively, but exist because of continued influx from elsewhere. Such a non-sustaining population, or the individuals within it, are said to be adventive. Cultivated plants are a major source of adventive populations. The above refers to ''naturalize'' as an intransitive verb, as in, "The species naturalized". In North America it is common to use ''naturalize'' as a transitive verb, as in, "City staff nat ...

North Meadow, Cricklade
North Meadow, Cricklade () is a hay meadow near the town of Cricklade, in Wiltshire, England. It is 24.6 hectares in size. It is a traditionally managed lowland hay-meadow, or ''lammas land'', and is grazed ''in common'' between 12 August and 12 February each year, and cut for hay no earlier than 1 July. This pattern of land use and management has existed for many centuries and has resulted in the species rich grassland flora and fauna present on the site. Over 250 species of higher plant occur in the meadow, but it is of particular note as it holds by far the largest British population of the snake's-head fritillary ('' Fritillaria meleagris''). The 500,000 fritillaries which flower each year represent 80% of the British population. History The meadow is situated between two rivers, the Thames and the Churn, and the unique habitat for the fritillary was created by regular winter flooding. Such meadows were once common in Britain, but with the advent of modern farming many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
