Platanus × Acerifolia
''Platanus'' × ''acerifolia'', ''Platanus'' × ''hispanica'', or hybrid plane, is a tree in the genus ''Platanus''. It is often known by the synonym London plane, or London planetree. It is usually thought to be a hybrid of ''Platanus orientalis'' (oriental plane) and ''Platanus occidentalis'' (American sycamore). Some authorities think that it may be a cultivar of ''P. orientalis''. Description The London plane is a large deciduous tree growing , exceptionally over tall, with a trunk up to or more in circumference. The bark is usually pale grey-green, smooth and exfoliating, or buff-brown and not exfoliating. The leaves are thick and stiff-textured, broad, palmately lobed, superficially maple-like, the leaf blade long and broad, with a petiole long. The young leaves in spring are coated with minute, fine, stiff hairs at first, but these wear off and by late summer the leaves are hairless or nearly so. The flowers are borne in one to three (most often two) dense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berkeley Square
Berkeley Square is a garden square in the West End of London. It is one of the best known of the many squares in London, located in Mayfair in the City of Westminster. It was laid out in the mid 18th century by the architect William Kent, and originally extended further south. The gardens' very large London Plane trees are among the oldest in central London, planted in 1789. Description Buildings Like most squares in British cities, it is surrounded largely by terraced houses, in this case grand townhouses. Originally these were the London residences of very wealthy families who would spend most of the year at their country house. Only one building, number 48, remains wholly residential. Most have been converted into offices for businesses typical of Mayfair, such as bluechips' meeting spaces, hedge funds, niche headhunters and wealth management businesses. The buildings' architects included Robert Adam but 9 Fitzmaurice Place (since 1935 home of the Lansdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maple
''Acer'' () is a genus of trees and shrubs commonly known as maples. The genus is placed in the family Sapindaceae.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008 nd more or less continuously updated since http://www.mobot.org/MOBOT/research/APweb/. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, ''Acer laurinum'', extends to the Southern Hemisphere.Gibbs, D. & Chen, Y.

Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until his death ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, '' Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also ''Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the ...

Hortus Kewensis
''Hortus Kewensis, or a Catalogue of the Plants Cultivated in the Royal Botanic Garden at Kew'' by William Aiton was a 1789 catalogue of all the plant species then in cultivation at the Royal Botanic Gardens, Kew Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 ..., which constituted the vast majority of plant species in cultivation in all of England. It included information on the country of origin, who introduced the plant into English cultivation, and when. It is therefore now one of the most important sources of information on history of horticulture in England. A second edition was published between 1810 and 1813; the bulk of the new information was added by Aiton's son William Townsend Aiton. In reference work, this is given the abbreviation ''Ait. Kew''.

Anthracnose
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animals can spread canker, thereby endangering areas that have only slight amount of canker. Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease. Examples * Apple canker, caused by the fungus ''Neonectria galligena'' * Ash bacterial canker, now understood to be caused by the bacterium ''Pseudomonas savastanoi'', rather than ''Pseudomonas syringae''. After DNA-relatedness studies ''Pseudomonas savastanoi'' has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Tradescant The Younger
John Tradescant the Younger (; 4 August 1608 – 22 April 1662), son of John Tradescant the Elder, was a botanist and gardener. The standard author abbreviation Trad. is applied to species he described. Biography Son of John Tradescant the Elder, he was born in Meopham, Kent, and educated at The King's School, Canterbury. Like his father, who collected specimens and rarities on his many trips abroad, he undertook collecting expeditions to Virginia between 1628 and 1637 (and possibly two more trips by 1662, though Potter and other authors doubt this). Among the seeds he brought back, to introduce to English gardens were great American trees, including magnolias, bald cypress and tulip tree, and garden plants such as phlox and asters. John Tradescant the Younger added his American acquisitions to the family's cabinet of curiosities, known as The Ark. These included the ceremonial cloak of Chief Powhatan, an important Native American relic. South Lambeth Road in Vauxha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vauxhall Gardens
Vauxhall Gardens is a public park in Kennington in the London Borough of Lambeth, England, on the south bank of the River Thames. Originally known as New Spring Gardens, it is believed to have opened before the Restoration of 1660, being mentioned by Samuel Pepys in 1662. From 1785 to 1859, the site was known as Vauxhall, a pleasure garden and one of the leading venues for public entertainment in London from the mid-17th century to the mid-19th century. The Gardens consisted of several acres of trees and shrubs with attractive walks. Initially entrance was free, with food and drink being sold to support the venture. It was accessed by boat until the erection of Vauxhall Bridge in the 1810s. The area was absorbed into the metropolis as the city expanded in the early to mid-19th century. The site became Vauxhall Gardens in 1785 and admission was charged for its attractions. The Gardens drew enormous crowds, with its paths being noted for romantic assignations. Tightrope w ...

Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
