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 pinks, reds, oranges and yellows. Most species are native to Asia, with smaller numbers native to Europe, North America, and Northwest 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'' com ...

Garden Roses
Garden roses are predominantly Hybrid (biology), hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars has been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedge, hedging. The cultivars are classified in a number of different and overlapping ways, generally without much reference to strict botany, botanical principles. Taking overall size and shape, the most common type is the bush rose, a rounded plant from 2 foot up to about 7 foot tall, above which height roses generally fall into the "'climbing and rambling'" class, the latter spreading wi ...

Hybrid Tea Rose
Hybrid tea is an informal horticultural classification for a group of garden roses. The first hybrid tea roses were created in France in the mid-1800s, by cross-breeding the large, floriferous Garden roses#Hybrid perpetual, hybrid perpetuals with the tall, elegant Garden roses#Tea, tea roses. The hybrid tea is the oldest class of Garden roses#Modern garden roses, modern garden roses. Hybrid teas exhibit traits midway between their parents, being hardier than the often delicate tea roses, and with a better ability for remontancy, repeat-flowering than the more robust hybrid perpetuals. Hybrid tea flowers are well-formed with large, high-centred buds, supported by long, straight and upright stems. Each flower can grow to 8–12.5 cm wide. Hybrid teas are the largest and most popular group of rose, due to their elegant form and large variety of colours. Their flowers are usually borne singly at the end of long stems which also makes them very popular as cut flowers. Description ...

Rosa Rubiginosa
''Rosa rubiginosa'' (sweet briar, sweetbriar rose, sweet brier or eglantine; synonym (taxonomy), syn. ''R. eglanteria'') is a species of rose native to Europe and western Asia. Description It is a dense deciduous shrub 2–3 meters high and across, with the stems bearing numerously hooked Spine (botany), prickles. The foliage has a strong apple-like fragrance. The leaf, leaves are pinnately compound, 5–9 cm long, with 5–9 rounded to oval leaflets with a serrated margin, and numerous glandular hairs. The flowers are 1.8–3 cm in diameter, the five petals being pink with a white base, and the numerous stamens yellow; the flowers are produced in clusters of 2–7 together, from late spring to mid-summer. The fruit is a globose to oblong red rose hip, hip 1–2 cm in diameter. Etymology Its name ''eglantine'' is from Middle English ''eglentyn'', from Old French ''aiglantin'' (adj.), from ''aiglent'' 'sweetbrier', from Vulgar Latin *''aculentus'' (with the endi ...

Rose 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 range of 320 to 350 is accepted by most botanists, but as Liberty H. Bailey has pointed out, the extreme '' lumpers'' Bentham and Hooker only allowed for 30 species, while the extreme '' splitter'' Michel Gandoger allowed 4,266 species just in Europe and West Asia. Subgenera and sections There are currently four subgenera in ''Rosa'', although there have been some disputes over the years.

Rosa Cinnamomea
''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, Czech Republic, 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 World Flora Online is an Internet-based compendium of the ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist 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 the son of a curate and was born in Råshult, in the countryside of Småland, 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 the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Avestan Language
Avestan ( ) is the liturgical language of Zoroastrianism. It belongs to the Iranian branch of the Indo-European language family and was originally spoken during the Old Iranian period ( – 400 BCE) by the Iranians living in the eastern portion of Greater Iran. After Avestan became extinct, its religious texts were first transmitted orally until being collected and put into writing during the Sasanian period ( – 500 CE). The extant material falls into two groups: Old Avestan ( – 900 BCE) and Younger Avestan ( – 400 BCE). The immediate ancestor of Old Avestan was the Proto-Iranian language, a sister language to the Proto-Indo-Aryan language, with both having developed from the earlier Proto-Indo-Iranian language. As such, Old Avestan is quite close in both grammar and lexicon to Vedic Sanskrit, the oldest preserved Indo-Aryan language. Name The Avestan texts consistently use the term Arya, i.e., Iranian, for the speakers of Avestan. The same term also app ...

Old Persian Language
Old Persian is one of two directly attested Old Iranian languages (the other being Avestan language, Avestan) and is the ancestor of Middle Persian (the language of the Sasanian Empire). Like other Old Iranian languages, it was known to its native speakers as (Iranian).''cf.'' , p. 2. Old Persian is close to both Avestan and Vedic Sanskrit, and all three languages are highly Inflection, inflected. Old Persian appears primarily in the inscriptions, clay tablets and Seal (emblem), seals of the Achaemenid dynasty, Achaemenid era ( to 300 BCE). Examples of Old Persian have been found in what is now Iran, Romania (Gherla), Armenia, Bahrain, Iraq, Turkey and Egypt, with the most important attestation by far being the contents of the Behistun Inscription (dated to 522 BCE). In 2007, research into the vast Persepolis Administrative Archives at the Oriental Institute at the University of Chicago unearthed Old Persian tablets, which suggest Old Persian was a written language in use f ...
