Tulipa
Tulips (''Tulipa'') are a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs). The flowers are usually large, showy and brightly coloured, generally red, pink, yellow, or white (usually in warm colours). They often have a different coloured blotch at the base of the tepals (petals and sepals, collectively), internally. Because of a degree of variability within the populations, and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to '' Amana'', ''Erythronium'' and '' Gagea'' in the tribe Lilieae. There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble by those who discovered it. Tulips originally were found in a band stretching from Southern Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liliaceae
The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals (undifferentiated petals and sepals) arranged in two whorls, six stamens and a superior ovary. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. Most species are grown from bulbs, although some have rhizomes. First described in 1789, the lily family became a paraphyletic "catch-all" (wastebasket) group of lilioid monocots that did not fit into other families and included a great number of genera now included in other families and in some cases in ...

Amana (plant)
''Amana'' is a small genus of flowering bulbs in the lily family, closely related to tulips and included in ''Tulipa'' by some authors. ''Amana'' is found in China, Japan and Korea.Honda, Masaji. 1935. Bulletin of the Biogeographical Society of Japan 6:20 the World Checklist of Selected Plant Families recognizes four species, three of which were formerly placed in the genus ''Tulipa Tulips (''Tulipa'') are a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs).

Lilieae
The Lilieae are a monophyletic tribe of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the lily family (Liliaceae). Taxonomy The term has varied over the years but in modern classification constitutes either a broad circumscription (Lilieae ''sensu lato'', ''s.l.'') with eight genera, placed in the subfamily Lilioideae, or narrower circumscription with six genera (Lilieae ''sensu stricto'', ''s.s.''), excluding ''Tulipa'' (which now includes '' Amana'') and ''Erythronium'' which are treated as a separate tribe, Tulipeae. Within Lilieae ''s.s.'', ''Gagea'' now includes '' Lloydia'', and ''Lilium'' includes ''Nomocharis'', reducing the number of genera to four, with about 260–300 species. Phylogeny The evolutionary and phylogenetic relationships between the genera currently included in Liliaceae are shown in this cladogram. Distribution and habitat Lilieae ''s.s.'' are distributed in temperate Northern Hemisphere areas, with the main centre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tulip Breaking Virus
''Tulip breaking virus'' is one of five plant viruses of the family ''Potyviridae'' that cause color-breaking of tulip flowers. These viruses infect plants in only two genera of the family Liliaceae: tulips (''Tulipa'') and lilies (''Lilium''). Also known as the tulip break virus, lily streak virus, lily mosaic virus, or simply TBV, ''Tulip breaking virus'' is most famous for its dramatic effects on the color of the tulip perianth, an effect highly sought after during the 17th-century Dutch "tulip mania". ''Tulip breaking virus'' is a potyvirus. A distant serological relationship between ''Tulip breaking virus'' and tobacco etch virus was discovered in 1971. ''Tulip breaking virus'' (TBV), tulip top-breaking virus (TTBV), tulip bandbreaking virus (TBBV), Rembrandt tulip-breaking virus (ReTBV), and lily mottle virus (LMoV) have all been identified as potyviruses by serology and potyvirus-specific polymerase chain reaction (PCR). In addition, sequence analysis of amplified DNA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tulip Mania
Tulip mania ( nl, tulpenmanie) was a period during the Dutch Golden Age when contract prices for some bulbs of the recently introduced and fashionable tulip reached extraordinarily high levels. The major acceleration started in 1634 and then dramatically collapsed in February 1637. It is generally considered to have been the first recorded speculative bubble or asset bubble in history. In many ways, the tulip mania was more of a then-unknown socio-economic phenomenon than a significant economic crisis. It had no critical influence on the prosperity of the Dutch Republic, which was one of the world's leading economic and financial powers in the 17th century, with the highest per capita income in the world from about 1600 to about 1720. The term "tulip mania" is now often used metaphorically to refer to any large economic bubble when asset prices deviate from intrinsic values. Forward markets appeared in the Dutch Republic during the 17th century. Among the most notable centre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Grasslands, Savannas, And Shrublands
Temperate grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The predominant vegetation in this biome consists of grass and/or shrubs. The climate is temperate and ranges from semi-arid to semi-humid. The habitat type differs from tropical grasslands in the annual temperature regime as well as the types of species found here. The habitat type is known as prairie in North America, pampas in South America, veld in Southern Africa and steppe in Asia. Generally speaking, these regions are devoid of trees, except for riparian or gallery forests associated with streams and rivers. Steppes/shortgrass prairies are short grasslands that occur in semi-arid climates. Tallgrass prairies are tall grasslands in areas of higher rainfall. Heaths and pastures are, respectively, low shrublands and grasslands where forest growth is hindered by human activity but not the climate. Tall grasslands, including the tallgrass prairie of North Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountainous
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain a ...

Temperate Climates
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arcti ...

Central Asia
Central Asia, also known as Middle Asia, is a subregion, region of Asia that stretches from the Caspian Sea in the west to western China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north. It includes the former Soviet Union, Soviet republics of the Soviet Union, republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, which are colloquially referred to as the "-stans" as the countries all have names ending with the Persian language, Persian suffix "-stan", meaning "land of". The current geographical location of Central Asia was formerly part of the historic region of Turkestan, Turkistan, also known as Turan. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian languages, Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians and the semi-nomadic Scythians and Dahae. After expansion by Turkic peop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near East
The ''Near East''; he, המזרח הקרוב; arc, ܕܢܚܐ ܩܪܒ; fa, خاور نزدیک, Xāvar-e nazdik; tr, Yakın Doğu is a geographical term which roughly encompasses a transcontinental region in Western Asia, that was once the historical Fertile Crescent, and later the Levant region. It also comprises Turkey (both Anatolia and East Thrace) and Egypt (mostly located in North Africa, with the Sinai Peninsula being in Asia). Despite having varying definitions within different academic circles, the term was originally applied to the maximum extent of the Ottoman Empire. According to the National Geographic Society, the terms ''Near East'' and ''Middle East'' denote the same territories and are "generally accepted as comprising the countries of the Arabian Peninsula, Cyprus, Egypt, Iraq, Iran, Israel, Jordan, Lebanon, Palestinian territories, Syria, and Turkey". In 1997, the Food and Agriculture Organization (FAO) of the United Nations defined the region similarly, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turban
A turban (from Persian دولبند, ''dulband''; via Middle French ''turbant'') is a type of headwear based on cloth winding. Featuring many variations, it is worn as customary headwear by people of various cultures. Communities with prominent turban-wearing traditions can be found in the Indian subcontinent, Southeast Asia, the Arabian Peninsula, the Middle East, the Balkans, the Caucasus, Central Asia, North Africa, West Africa, East Africa, and amongst some Turkic peoples in Russia as well as Ashkenazi Jews. A keski is a type of turban, a long piece of cloth roughly half the length of a traditional "single turban", but not cut and sewn to make a double-width "Double Turban" (or Double Patti). Wearing turbans is common among Sikh men, and infrequently women. They are also worn by Hindu monks. The headgear also serves as a religious observance, including among Shia Muslims, who regard turban-wearing as ''Sunnah mu’akkadah'' (confirmed tradition). The turban is also the t ...
