Rosa Gallica
''Rosa gallica'', the Gallic rose, French rose, or rose of Provins, is a species of flowering plant in the rose family, native to southern and central Europe eastwards to Turkey and the Caucasus. ''Rosa gallica'' was one of the first species of rose to be cultivated in central Europe. It is a parent of several important cultivars. Description ''Rosa gallica'' is a deciduous shrub forming large patches. The slender, straight prickles are various in size and frequency in this species. The leaves are pinnately-compound, with three to seven bluish-green leaflets. The flowers are clustered one to four together, on glandular pedicels. Each flower has five or more petals, sometimes producing double corollas. The flowers are fragrant and deep pink. The hips are globose to ovoid, 10–13 mm diameter, and orange to brownish. In the field of Food science, rose petal extract from ''Rosa gallica'' has been shown to have properties that reduce inflammation and wrinkling in human skin. ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, 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 (biology), 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 ...

Inflammation
Inflammation (from la, inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants, and is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out necrotic cells and tissues damaged from the original insult and the inflammatory process, and initiate tissue repair. The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin ''calor'', ''dolor'', ''rubor'', ''tumor'', and ''functio laesa''). Inflammation is a generic response, and therefore it is considered as a mechanism of innate immunity, as compared to adaptive immunity, which is specific for each pathogen. Too little inflammation could lead to progressive tissue destruction by the harmful stimulus (e.g. bacteria) and compromise the survival of the organism. In contrast, too much inflammation, in ...

Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black ...

Roses
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 Lati ...

Blue Rose
A blue rose is a flower of the genus ''Rosa'' (family Rosaceae) that presents blue-to-violet pigmentation instead of the more common red, white, or yellow. Blue roses are often used to symbolize mystery or attaining the impossible. However, because of genetic limitations, they do not exist in nature. In 2004, researchers used genetic modification to create roses that contain the blue pigment delphinidin. So-called "blue roses" have been bred by conventional hybridization methods, but the results, such as "Blue Moon", are more accurately described as lilac in color. Dyed roses Since blue roses do not exist in nature, as roses lack the specific gene that has the ability to produce a "true blue" color, blue roses are traditionally created by dyeing white roses. In a book entitled ''Kitāb al-filāḥah'' written by Ibn al-'Awwām al-Ishbīlī in Arabic in the 12th century, and translated into French by J. J. Clement as ''Le livre de l'agriculture,'' there are references to azu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Engineering
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or " knock out", genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome. An organism that is generated through genetic engineering is considered to be genetically modified (G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rosa × Damascena
''Rosa'' × ''damascena'' (Latin for damascene rose), more commonly known as the Damask rose, or sometimes as Bulgarian rose, Turkish rose, Taif rose, Arab rose, Ispahan rose and Castile rose, is a rose hybrid, derived from ''Rosa gallica'' and '' Rosa moschata''. DNA analysis has shown that a third species, '' Rosa fedtschenkoana'', has made some genetic contributions to the Damask rose. The flowers are renowned for their fine fragrance, and are commercially harvested for rose oil (either "rose otto" or "rose absolute") used in perfumery and to make rose water and "rose concrete". The flower petals are also edible. They may be used to flavor food, as a garnish, as an herbal tea, and preserved in sugar as gulkand. Description The Damask rose is a deciduous shrub growing to tall, the stems densely armed with stout, curved prickles and stiff bristles. The leaves are pinnate, with five (rarely seven) leaflets. The roses are a light to moderate pink to light red. The relati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lancashire
Lancashire ( , ; abbreviated Lancs) is the name of a historic county, ceremonial county, and non-metropolitan county in North West England. The boundaries of these three areas differ significantly. The non-metropolitan county of Lancashire was created by the Local Government Act 1972. It is administered by Lancashire County Council, based in Preston, and twelve district councils. Although Lancaster is still considered the county town, Preston is the administrative centre of the non-metropolitan county. The ceremonial county has the same boundaries except that it also includes Blackpool and Blackburn with Darwen, which are unitary authorities. The historic county of Lancashire is larger and includes the cities of Manchester and Liverpool as well as the Furness and Cartmel peninsulas, but excludes Bowland area of the West Riding of Yorkshire transferred to the non-metropolitan county in 1974 History Before the county During Roman times the area was part of th ...

County Flower
In a number of countries, plants have been chosen as symbols to represent specific geographic areas. Some countries have a country-wide floral emblem; others in addition have symbols representing subdivisions. Different processes have been used to adopt these symbols – some are conferred by government bodies, whereas others are the result of informal public polls. The term floral emblem, which refers to flowers specifically, is primarily used in Australia and Canada. In the United States, the term state flower is more often used. National plants Africa Mauritius The national flower of Mauritius is ''Trochetia boutoniana''. Seychelles The national flower of the Seychelles is the tropicbird orchid (known locally as ''orkid payanke''), ''Angraecum eburneum''. South Africa The national flower of South Africa is the Protea cynaroides, King Protea, ''Protea cynaroides''. Tunisia The national flower of Tunisia is jasmine.

Red Rose Of Lancaster
The Red Rose of Lancaster (blazoned: ''a rose gules'') was the heraldic badge adopted by the royal House of Lancaster in the 14th century. In modern times it symbolises the county of Lancashire. The exact species or cultivar which it represents is thought to be '' Rosa gallica officinalis''. The red rose was first adopted as a heraldic badge by John of Gaunt, 1st Duke of Lancaster (1340–1399) third surviving son of King Edward III of England and father of King Henry IV, the first Lancastrian king, who seized the throne from his first cousin King Richard II. John of Gaunt's younger brother Edmund of Langley, 1st Duke of York (1341–1402), adopted the White rose of York as his heraldic badge. Their respective descendants fought for control of the throne of England during several decades of civil warfare, which became known as the Wars of the Roses, after the badges of the two competing cadet royal houses. During the civil wars of the fifteenth century the red rose was the symbol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
