Rosa Mollis
''Rosa mollis'' is a species of wild rose. Common name: soft downy-rose. It is most closely related to ''Rosa villosa''. ''Rosa mollis'' can be distinguished from ''Rosa villosa'' by its longer leaves and pruinose stem, which is absent in the latter. ''Rosa mollis'' usually blossoms in Germany for approximately 5 weeks from the end of June to July It is native to the Caucasus and parts of Europe: the British Isles, Scandinavia, and the lands around the Baltic. It has been commonly reported in isolated areas throughout the rest of Europe; this fact has prompted the editors of ''Atlas Florae Europaeae'' to raise the question whether these may not be cases of misidentification of either ''Rosa villosa'' or ''Rosa sherardii''.

James Edward Smith (botanist)
__NOTOC__ Sir James Edward Smith (2 December 1759 – 17 March 1828) was an English botanist and founder of the Linnean Society. Early life and education Smith was born in Norwich in 1759, the son of a wealthy wool merchant. He displayed a precocious interest in the natural world. During the early 1780s he enrolled in the medical course at the University of Edinburgh where he studied chemistry under Joseph Black and natural history under John Walker. He then moved to London in 1783 to continue his studies. Smith was a friend of Sir Joseph Banks, who was offered the entire collection of books, manuscripts and specimens of the Swedish natural historian and botanist Carl Linnaeus following the death of his son Carolus Linnaeus the Younger. Banks declined the purchase, but Smith bought the collection for the bargain price of £1,000. The collection arrived in London in 1784, and in 1785 Smith was elected Fellow of the Royal Society. Academic career Between 1786 and 1788 Smit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pruinose
Pruinescence , or pruinosity, is a "frosted" or dusty-looking coating on top of a surface. It may also be called a pruina (plural: ''pruinae''), from the Latin word for hoarfrost. The adjectival form is pruinose . Entomology In insects, a "bloom" caused by wax particles on top of an insect's cuticle covers up the underlying coloration, giving a dusty or frosted appearance. The pruinescence is commonly white to pale blue in color but can be gray, pink, purple, or red; these colors may be produced by Tyndall scattering of light. When pale in color, pruinescence often strongly reflects ultraviolet. Pruinescence is found in many species of Odonata, particularly damselflies of the families Lestidae and Coenagrionidae, where it occurs on the wings and body. Among true dragonflies it is most common on male Libellulidae (skimmers). In the common whitetail and blue dasher dragonflies (''Plathemis lydia'' and ''Pachydiplax longipennis''), males display the pruinescence on the back of th ...

Caucasus
The Caucasus () or Caucasia (), is a region between the Black Sea and the Caspian Sea, mainly comprising Armenia, Azerbaijan, Georgia, and parts of Southern Russia. The Caucasus Mountains, including the Greater Caucasus range, have historically been considered as a natural barrier between Eastern Europe and Western Asia. Mount Elbrus in Russia, Europe's highest mountain, is situated in the Western Caucasus. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands, part of which is in Turkey. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is occupied by several independent states, mostly by Armenia, Azerbaijan, and Georgia, but also ...
