Platanus X Acerifolia
The London plane, or sometimes hybrid plane, ''Platanus'' × ''hispanica'', is a tree in the genus ''Platanus''. It is often known by the synonym ''Platanus'' × ''acerifolia'', a later name. It is a hybrid of ''Platanus orientalis'' (oriental plane) and ''Platanus occidentalis'' (American sycamore). Description The London plane is a large deciduous tree growing , exceptionally to tall, with a trunk up to 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 spherical inflorescences on a pendulous stem, with male and female flowers on separate stems ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in ) 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'', 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. Definitions The term is defined in different ways by different authors. However, the International Code of Nomenclature for Cultivated Plants, while recognizing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hortus Kewensis
(Latin for 'Kew Garden'; abbr. ) is a series of works cataloguing the plant species in cultivation at the Royal Botanic Gardens at Kew in the late 18th and early 19th centuries. Background Kew became a favored location for English courtiers after the establishment of Richmond Palace nearby under the Tudors. The Royal Botanic Gardens at Kew began as the private garden of Henry Capell of Tewkesbury and then Samuel Molyneux, who served as secretary to Frederick, Prince of Wales, son of George II and father of George III of England. Frederick then leased Kew House, began planning an enormous greenhouse, and had his close friend John Stuart, earl of Bute, begin requesting plant specimens from British agents around the world. After his death, Frederick's widow Augusta expanded its gardens still further in cooperation with Bute and William Aiton. John Hill's edition The first edition of was published in Latin in 1768. It was compiled by John Hill at Augusta's request and lis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 (via frost or windstorm damage) and animal damage can also cause stress to the plant resulting in cankers. Other causes of cankers is pruning when the bark is wet or using un-sterilized tools. 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'' formerly Nectria galligena. * Ash bacterial canker, now understood to be caused by the bacterium '' Pseu ...

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 List of botanists by author abbreviation, 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, 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, a ...

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. The pleasure grounds was accessed by boats on the Thames 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 roman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Sycamore
''Platanus occidentalis'', also known as American sycamore, American planetree, western plane, occidental plane, buttonwood, and water beech, is a species of ''Platanus'' native to the eastern and central United States, the mountains of northeastern Mexico, extreme southern Ontario, and extreme southern Quebec. It is usually called sycamore in North America, a name which can refer to other types of trees in other parts of the world; in the United Kingdom, for example, the name sycamore typically refers to ''Acer pseudoplatanus''. The American sycamore is a long-lived species, typically surviving at least 200 years and likely as long as 500–600 years. The species epithet ''occidentalis'' is Latin for "western", referring to the Western Hemisphere, because at the time when it was named by Carl Linnaeus, the only other species in the genus was '' P. orientalis'' ("eastern"), native to the Eastern Hemisphere. Confusingly, in the United States, this species was first known in the Ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple fruit, simple dry fruits, dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and Dehiscence (botany), 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 encom ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other 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 and culinary 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'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
