Rosa Oxyodon
''Rosa oxyodon'' is a species of wild rose native to the Caucasus. It is closely related to ''Rosa pendulina''. There have been various hypotheses about its evolutionary origin. According to one, it originated from the ancestor of ''R. pendulina'' as it migrated from Central Asia to Europe; in that view, the rare '' R. donetzica'' would be another relict of this migration. There is a second hypothesis, based on genetic data, which proposes that ''R. oxyodon'' arose as a separate species out of a series of hybridisations between '' R. majalis'' and ''R. pendulina''. The presence of ''Rosa oxyodon'' was reported in one place outside the Caucasus in 1967: in the Balkan Mountains The Balkan mountain range (, , known locally also as Stara planina) is a mountain range in the eastern part of the Balkan Peninsula in Southeastern Europe. The range is conventionally taken to begin at the peak of Vrashka Chuka on the border betw ... of Bulgaria, specifically in a single location near Koz ...

Pierre Edmond Boissier
Pierre Edmond Boissier (25 May 1810 Geneva – 25 September 1885 Valeyres-sous-Rances) was a Swiss prominent botanist, explorer and mathematician. He was the son of Jacques Boissier (1784-1857) and Caroline Butini (1786-1836), daughter of Pierre Butini (1759-1838) a well-known physician and naturalist from Geneva. With his sister, Valérie Boissier (1813-1894), he received a strict education with lessons delivered in Italian and Latin. Edmond's interest in natural history stemmed from holidays in the company of his mother and his grandfather, Pierre Butini at Valeyres-sous-Rances. His hikes in the Jura and the Alps laid the foundation of his zest for later exploration and adventure. He attended a course at the Academy of Geneva given by Augustin Pyramus de Candolle. Edmond Boissier collected extensively in Europe, North Africa and western Asia, on occasion accompanied by his daughter, Caroline Barbey-Boissier (1847-1918) and her husband, William Barbey (1842-1914), who collect ...

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 ...

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 ...

Rosa Pendulina
''Rosa pendulina'', (syn. ''Rosa alpina''), the Alpine rose or mountain rose, is a species of wild rose found in the mountains of central and southern Europe. It appears to have survived in glacial refugia in the Alps and Carpathians, and spread out from there. A climbing shrub with deep pink flowers and relatively few thorns, it has had a history of cultivation as an ornamental plant. Description ''Rosa pendulina'' is a climbing (or rambling) shrub between 0.5 and 2m, rarely 3m tall. The flowers are typically semi-doubled and deep pink to fuchsia, brightening towards the center. It can be distinguished from other members of its genus by its relative lack of thorns (prickles), especially higher up on the plant, its oblong fruits (hips) which hang downwards (are pendulous, hence the specific epithet), its hispid peduncles and petioles, and its smooth stems and branches. The chromosome number is 4n = 28. Distribution It prefers to grow in relatively warmer, shadier, and wetter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosa Donetzica
''Rosa donetzica'' is a species of rose in the family Rosaceae, native to Ukraine Ukraine ( uk, Україна, Ukraïna, ) is a country in Eastern Europe. It is the second-largest European country after Russia, which it borders to the east and northeast. Ukraine covers approximately . Prior to the ongoing Russian inv ... and south European Russia, generally near the eastern Black Sea. It is a rare endemic typically found growing in rocky areas, and is decreasing in abundance due to pressure from grazing and stone quarrying.

Rosa Majalis
''Rosa majalis'' (syn. ''R. cinnamomea'' sensu L. 1759, non 1753; ''R. cinnamomea'' auct. non L.; cinnamon rose; double cinnamon rose) is a species of deciduous shrubs in the genus ''Rosa'', native to forests of Europe and Siberia. It grows to 2 m. and yields edible hip fruits rich in vitamin C, which are used in medicine and to produce rose hip syrup. It is native to Siberia and northern Europe. Its European distribution encompasses much of European Russia, the Baltic countries and Scandinavia (without Denmark), with more isolated occurrences in Central Europe, primarily in wet habitats in Ukraine, Belarus, Poland, Czechia, Germany and the Alps. It has a history of cultivation in gardens, which in Britain dates to the 16th century. The binomial name ''Rosa majalis'' and its synonym ''Rosa cinnamomea'' are both ambiguous and have variously been applied to other species of ''Rosa''.See the ''World Flora Online'' entries foRosa majalis anRosa cinnamomea References majalis ...

Balkan Mountains
The Balkan mountain range (, , known locally also as Stara planina) is a mountain range in the eastern part of the Balkan Peninsula in Southeastern Europe. The range is conventionally taken to begin at the peak of Vrashka Chuka on the border between Bulgaria and Serbia. It then runs for about , first in a south-easterly direction along the border, then eastward across Bulgaria, forming a natural barrier between the northern and southern halves of the country, before finally reaching the Black Sea at Cape Emine. The mountains reach their highest point with Botev Peak at . In much of the central and eastern sections, the summit forms the watershed between the drainage basins of the Black Sea and the Aegean. A prominent gap in the mountains is formed by the sometimes narrow Iskar Gorge, a few miles north of the Bulgarian capital, Sofia. The karst relief determines the large number of caves, including Magura, featuring the most important and extended European post-Palaeolithic cave ...

Rosa Spinosissima
''Rosa pimpinellifolia'', the burnet rose, is a species of rose native to western, central and southern Europe (north to Iceland and Norway) and northwest Africa. Habitat It is generally restricted to sand dunes or limestone pavements and typically has a coastal distribution when not on limestone. Description It is a rather low erect deciduous plant usually from 20–140 cm high but sometimes up to 2 metres. It spreads by basal shoots and can cover large areas. The stems have very numerous stiff bristles and many straight prickles. The young stems and prickles and the mature leaves tend to be very red with young growth a bright scarlet and older growth a deep maroon. The flowers are cream-white although rarely also pale pink. They are 2–4 cm diameter with five petals, which produce a distinctive globular dark purple to black hips. Similar plants native further east in Asia, sometimes treated as ''Rosa pimpinellifolia'' var. ''subalpina'', are now regarded as a sepa ...

Flora Of The Caucasus
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] |
