Rosa Hemisphaerica
''Rosa hemisphaerica'', also known as the sulphur rose, is a rose species with pale yellow flowers native to western Asia. The wild form, known as ''Rosa raphinii'', has single flowers with five petals. A double-flowered form was one of the first yellow roses introduced to European gardens; John Bellenden Ker Gawler stated in 1815 that the species had been cultivated in England for nearly 200 years. The scent of the flowers has been described as unpleasant. Etymology The name ''Rosa hemisphaerica'' refers to the half-rounded fruit and ovaries, Latin "''pomo hemisphaerico ... Germen hemisphaericum''". Description ''Rosa hemisphaerica'' is a prickly shrub that grows to about high with grey-green leaves of five to seven leaflets. The hips In vertebrate anatomy, hip (or "coxa"Latin ''coxa'' was used by Celsus in the sense "hip", but by Pliny the Elder in the sense "hip bone" (Diab, p 77) in medical terminology) refers to either an anatomical region or a joint.

Pierre-Joseph Redouté
Pierre-Joseph Redouté (, 10 July 1759 – 19 June 1840), was a painter and botanist from Belgium, known for his watercolours of roses, lilies and other flowers at the Château de Malmaison, many of which were published as large, coloured stipple engravings. He was nicknamed "the Raphael of flowers" and has been called the greatest botanical illustrator of all time.Schmidt, Alesandra M., and Trudy B. Jacoby"Herbs to Orchids: Botanical Illustration in the Nineteenth Century" Watkinson Exhibition Catalogs, Paper 3, 1996. Redouté was an official court artist of Marie Antoinette, and continued painting through the French Revolution and Reign of Terror. He survived the turbulent political upheaval to gain international recognition for his precise renderings of plants, which remain as fresh in the early 21st century as when first painted. He combined great artistic skills with a pleasing, ingratiating personality which assisted him with his influential patrons. After Queen Marie- ...

Johann Hermann
Johann, or Jean-Frederic, Hermann, or Herrmann, (31 December 1738 in Barr, Alsace – 4 October 1800 in Strasbourg) was a French physician and naturalist. In 1769 he was appointed professor of medicine at the School of Public Health of Strasbourg, then, in 1778, professor of philosophy, before going on, in 1784, to succeed Jacob Reinbold Spielmann as chair of chemistry, natural history and materia medica. In 1794 he became professor of botany and materia medica in the new School of Medicine. He was the author of ''Tabula affinitatum animalium '' (1783) and ''Observationes zoologicae quibus novae complures'', published posthumously in 1804. His collections and library of 18,000 volumes formed the basis of the Natural History Museum of Strasbourg, where a reconstruction of his natural history cabinet was opened in 1988 . Hermann was also in charge of Strasbourg's botanical garden, where he was responsible for a large increase in the number of living plant species. The garden ...

John Bellenden Ker Gawler
John Bellenden Ker, originally John Gawler, was an English botanist born about 1764 in Ramridge, Andover, Hampshire and died in June 1842 in the same town. On 5 November 1804 he changed his name to Ker Bellenden, but continued to sign his name as Bellenden Ker until his death. He was an unsuccessful claimant to the Roxburghe dukedom. His son was the legal reformer Charles Henry Bellenden Ker. He is noted for having written ''Recensio Plantarum'' (1801), ''Select Orchideae'' (c. 1816) and ''Iridearum Genera'' (1827). He contributed to Curtis's Botanical Magazine under John Sims, using the initial G. He edited Edward's Botanical Register from 1815 to 1824 and was famous as a wit and botanist as well as being the author of ''Archaeology of Popular Phrases and Nursery Rhymes'' (1837). The 2nd volume of this work was published in 1840. Robert Brown (1773–1858) named the genus '' Bellendena'' of the Proteaceae in his honour in 1810. The state of Queensland in Australia has named ...

Rose Hip
The rose hip or rosehip, also called rose haw and rose hep, is the accessory fruit of the various species of rose plant. It is typically red to orange, but ranges from dark purple to black in some species. Rose hips begin to form after pollination of flowers in spring or early summer, and ripen in late summer through autumn. Propagation Roses are propagated from rose hips by removing the achenes that contain the seeds from the hypanthium (the outer coating) and sowing just beneath the surface of the soil. The seeds can take many months to germinate. Most species require chilling (stratification), with some such as ''Rosa canina'' only germinating after two winter chill periods. Use Rose hips are used in bread and pies, jam, jelly, marmalade, syrup, soup, tea, wine, and other beverages. Rose hips can be eaten raw, like berries, if care is taken to avoid the hairs inside the fruit. The hairs are used as itching powder. A few rose species are sometimes grown for the ornament ...

List Of Rosa Species
There is significant disagreement over the number of true rose species. Some species are so similar that they could easily be considered variations of a single species, while other species show enough variation that they could easily be considered to be different species. Lists of rose species usually show more than 320. The numbers 320 to 350 are the figures accepted by most botanists, but as Bailey has pointed out the extreme lumpers Bentham and Hooker only allowed for thirty species, while the extreme splitter Michel Gandoger allowed 4266 species just in Europe and western Asia. Subgenera and sections There are currently four subgenera in ''Rosa'' although there has been some disputes over the years.', The genus Rosa (Rosoideae, Rosaceae) revisited: molecular analysis of nrITS-1 and atpB-rbcL intergenic spacer (IGS) versus conventional taxonomy, 2005 The four subgenera are: *''Hulthemia'' (formerly ''Simplicifoliae'', meaning "with single leaves") containing one or two sp ...

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 Lat ...

Flora Of Western Asia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Johann Hermann
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
