Rosa Fedtschenkoana
''Rosa fedtschenkoana'' is a species in the plant genus ''Rosa'' in the family Rosaceae. Some authorities consider it a synonym of ''Rosa webbiana''. It is native to the foothills of the Ala Tau, Tian Shan and Pamir-Alai mountain ranges in central Asia and northwest China. It is named after Olga Fédchenko, a Russian botanist. It is deciduous, forming a bushy and suckering shrub up to 2.5 metres high and as much across. The branches are covered in many prickles, many of which are fine and straight, but some are thicker and slightly hooked. The pinnate leaves are pale greyish green in colour and have usually between 7 and 9 leaflets. The flowers are white, up to 5 cm across, and are borne singly or in small clusters at the tips of the branches throughout the summer months. The flowers' scent has been described as being "like 'Hovis' rownbread with a little blackberry jam". The flowers are followed by small, pear-shaped, bristly orange-red fruits.

Eduard August Von Regel
Eduard August von Regel (sometimes Edward von Regel or Edward de Regel or Édouard von Regel), Russian: Эдуард Август Фон Регель; (born 13 August 1815 in Gotha; died 15 April 1892 in St. Petersburg) was a German horticulturalist and botanist. He ended his career serving as the Director of the Russian Imperial Botanical Garden of St. Petersburg. As a result of naturalists and explorers sending back biological collections, Regel was able to describe and name many previously unknown species from frontiers around the world. History Regel was the son of the teacher and garrison-preacher Ludwig A. Regel. Already as a child he liked growing fruits and learnt to prune apple trees from a gardener of his grandfather Döring and cultivated the garden of his parents. He visited the Gymnasium at Gotha but left without Abitur Regel earned a degree from the University of Bonn. At 15, Regel began his career as an apprentice at the Royal Garden Limonaia in Gotha in 1830 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinnate
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or "fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Plants Botanically, pinnation is an arrangement of discr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Central 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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Remontancy
Remontancy is the ability of a plant to flower more than once during the course of a growing season or year. It is a term applied most specifically to roses, and roses possessing this ability are called "repeat flowering" or remontant. The term originated in the nineteenth century from the French verb ''remonter'' or 'coming up again'.''Dictionary of the English Language'', Collins, 1979, p1235 Roses which lack this ability are termed "summer flowering", "once flowering" or non-remontant. Few wild rose species possess remontancy; notable exceptions being '' Rosa chinensis'', ''Rosa rugosa'' and '' Rosa fedtschenkoana''. As remontancy is considered a desirable horticultural characteristic, it is preferentially selected for by rose hybridisers. Remontant roses descended from ''Rosa chinensis'' have been grown in China for at least a thousand years,Quest-Ritson, C. & Quest-Ritson, B., ''The Royal Horticultural Society Encyclopedia of Roses'', Dorling Kindersley, 2003. but the first g ...

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. ...

Rosa Moschata
''Rosa moschata'', the musk rose, is a species of rose which has been long in cultivation. Its wild origins are uncertain but are suspected to lie in the western Himalayas. Description ''Rosa moschata'' is a shrub (to 3m) with single white 5 cm flowers in a loose cyme or corymb, blooming on new growth from late spring until late autumn in warm climates, or from late summer onwards in cool-summer climates. The sepals are 2 cm long with slender points. The flowers have a characteristic "musky" scent, emanating from the stamens, which is also found in some of its descendants. The prickles on the stems are straight or slightly curved and have a broad base. The light- or greyish-green leaves have 5 to 7 ovate leaflets with small teeth; the veins are sometimes pubescent and the rachis bears prickles. The stipules are narrow with spreading, free tips. Small, ovate fruits called hips are borne, turning orange-red in autumn, popular rosehip seed oil is processed with Rosa mosc ...

Thorns, Spines, And Prickles
In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called ''spinose teeth'' or ''spinose apical processes''), are hard, rigid extensions or modifications of leaves, roots, stems or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals from eating the plant material. Description In common language the terms are used more or less interchangeably, but in botanical terms, thorns are derived shoots (so that they may or may not be branched, they may or may not have leaves, and they may or may not arise from a bud),Simpson, M.

Deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of ''deciduous'' in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called abscissio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olga Fédchenko
Olga Aleksandrovna Fedchenko or Fedtschenko ( Armfeld; 30 October 1845 – 24 April 1921) was a Russian botanist. ''Rosa fedtschenkoana'', which is found in Asia, was named in her honour (with a German transliteration of her name). Early life Ol'ga (Olga) Armfeld was born in Moscow in 1845. Her father was Alexandre Armfeldt who was a professor at the University of Moscow. She was educated at home until she was eleven when she went to school where she showed an interest in Botany. She began collecting plants and from about 1861 she was using her art and language skills to translate academic descriptions from English, French and German naturalists. She was preparing illustrations, communicating with foreign naturalists and visiting the University's Zoological Museum. She worked for several years before she met the geologist, Alexei Pavlovich Fedchenko. Marriage and Turkestan She married the recently qualified Moscow University geology graduate Fedchenko on 2 July 1867. She and her ...
