Leyland Cypress
The Leyland cypress, ''Cupressus'' × ''leylandii'', × ''Cuprocyparis leylandii'' or × ''Cupressocyparis leylandii'', often referred to simply as leylandii, is a fast-growing coniferous evergreen tree much used in horticulture, primarily for hedges and screens. Even on sites of relatively poor culture, plants have been known to grow to heights of in 16 years. Their rapid, thick growth means they are sometimes used to achieve privacy, but such use can result in disputes with neighbours whose own property becomes overshadowed. The tree is a hybrid of Monterey cypress (''Cupressus macrocarpa'') and Nootka cypress ('' Cupressus nootkatensis''). It is almost always sterile, and is propagated mainly by cuttings. History In 1845, the Leighton Hall, Powys estate was purchased by the Liverpool banker Christopher Leyland. In 1847, he gave it to his nephew John Naylor (1813–1889). Naylor commissioned Edward Kemp to lay out the gardens, which included redwoods, monkey puzzle tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Forestry Society
The Royal Forestry Society (RFS) is an educational charity and one of the oldest membership organisations in England, Wales and Northern Ireland for those actively involved in woodland management. The RFS has a broad membership which includes woodland owners, managers, countryside professionals (land agents, ecologists, conservationists), academics, students and others with a general interest in woodland management. Membership is open to all. History The Royal Forestry Society was established in 1882 in Northumberland, England. Originally known as the English Arboricultural Society, the organisation was founded by forester Henry Clark and nursery (horticulture), nurseryman John W Robson, both from Hexham. The Society's first President was John Lambton, 1st Earl of Durham. In 1905 it was granted a Royal Charter by King Edward VII and was renamed the Royal English Arboricultural Society. It was renamed The Royal English Forestry Society in 1931, and in 1962 its title was changed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupressus
''Cupressus'' (common name cypress) is one of several genus, genera of evergreen conifers within the Family (biology), family Cupressaceae; for the others, see cypress. It is considered a Polyphyly, polyphyletic group. Based on genetic and morphological analysis, the genus ''Cupressus'' is found in the subfamily Cupressoideae. The common name "cypress" comes via the Old French from the Latin , which is the Latinisation (literature), latinisation of the Greek language, Greek κυπάρισσος (''kypárissos''). The name derives from Cyparissus, a mythological figure who was turned into a tree after killing a stag. As currently treated, these cypresses are native plants in scattered localities in mainly warm temperate climate regions in the Northern Hemisphere, including northwest Africa, the Middle East, the Himalayas, southern China and northern Vietnam. As with other pinophyta, conifers, extensive cultivation has led to a wide variety of forms, sizes and colours, that are gro ...

Sterility (physiology)
Sterility is the physiological inability to effect sexual reproduction in a living thing, members of whose kind have been produced sexually. Sterility has a wide range of causes. It may be an inherited trait, as in the mule; or it may be acquired from the environment, for example through physical injury or disease, or by exposure to radiation. Sterility is the inability to produce a biological child, while infertility is the inability to conceive after a certain period. Sterility is rarely discussed in clinical literature and is often used synonymously with infertility. Infertility affects about 12-15% of couples globally. Still, the prevalence of sterility remains unknown. Sterility can be divided into three subtypes natural, clinical, and hardship. Natural sterility is the couple's physiological inability to conceive a child. Clinical sterility is natural sterility for which treatment of the patient will not result in conception. Hardship sterility is the inability to take adv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vesicle (biology And Chemistry)
In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion ( exocytosis), uptake (endocytosis), and the transport of materials within the plasma membrane. Alternatively, they may be prepared artificially, in which case they are called liposomes (not to be confused with lysosomes). If there is only one phospholipid bilayer, the vesicles are called ''unilamellar liposomes''; otherwise they are called ''multilamellar liposomes''. The membrane enclosing the vesicle is also a lamellar phase, similar to that of the plasma membrane, and intracellular vesicles can fuse with the plasma membrane to release their contents outside the cell. Vesicles can also fuse with other organelles within the cell. A vesicle released from the cell is known as an extracellular vesicle. Vesicles perform a variety of functions. Because it is separated from the cytosol, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cone
In geometry, a cone is a three-dimensional figure that tapers smoothly from a flat base (typically a circle) to a point not contained in the base, called the '' apex'' or '' vertex''. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base. In the case of line segments, the cone does not extend beyond the base, while in the case of half-lines, it extends infinitely far. In the case of lines, the cone extends infinitely far in both directions from the apex, in which case it is sometimes called a ''double cone''. Each of the two halves of a double cone split at the apex is called a ''nappe''. Depending on the author, the base may be restricted to a circle, any one-dimensional quadratic form in the plane, any closed one-dimensional figure, or any of the above plus all the enclosed points. If the enclosed points are included in the base, the cone is a solid object; otherwise it is an open surface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown (botany)
The crown of a plant is the total of an individual plant's aboveground parts, including stems, leaves, and reproductive structures. A plant community canopy consists of one or more plant crowns growing in a given area. The crown of a woody plant (tree, shrub, liana) is the branches, leaves, and reproductive structures extending from the trunk or main stems. Shapes of crowns are highly variable. The major types for trees are the excurrent branching habit resulting in conoid shapes and decurrent (deliquescent) branching habit, resulting in round shapes. Crowns are also characterized by their width, depth, surface area, volume, and density. Measurements of crowns are important in quantifying and qualifying plant health, growth stage, and efficiency. Major functions of the crown include light energy assimilation, carbon dioxide absorption and release of oxygen via photosynthesis, energy release by respiration, and movement of water to the atmosphere by transpiration. These f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twig
A twig is a thin, often short, branch of a tree or Bush (plant), bush. The buds on the twig are an important diagnostic characteristic, as are the abscission scars where the leaves have fallen away. The color, texture, and patterning of the twig bark (botany), bark are also important, in addition to the thickness and nature of any pith of the twig.Alan Crivellaro and Fritz Hans Schweingruber There are two types of twigs: vegetative twigs and fruiting spurs. Fruiting spurs are specialized twigs that generally branch off the sides of branches and are stubby and slow-growing, with many annular dendrochronology, ring markings from seasons past. The twig's age and rate of growth can be determined by counting the winter terminal bud scale scars, or annular ring marking, across the diameter of the twig. Uses Twigs can be useful in starting a Campfire, fire. They can be used as wikt:kindling, kindling wood, bridging the gap between highly flammable tinder (dry grass and leaves) and ...

Arboretum
An arboretum (: arboreta) is a botanical collection composed exclusively of trees and shrubs of a variety of species. Originally mostly created as a section in a larger garden or park for specimens of mostly non-local species, many modern arboreta are in botanical gardens as living collections of woody plants and are intended at least in part for scientific study. In Latin, an ''arboretum'' is a place planted with trees, not necessarily in this specific sense, and "arboretum" as an English word is first recorded used by John Claudius Loudon in 1833 in ''The Gardener's Magazine'', but the concept was already long-established by then. An arboretum specializing in growing conifers is known as a pinetum. Other specialist arboreta include saliceta (willows), populeta (Populus, poplar), and querceta (oaks). Related collections include a fruticetum, from the Latin ''frutex'', meaning ''shrub'', much more often a shrubbery, and a viticetum (from the Latin ''vitis,'' meaning vine, refe ...

Castlewellan
Castlewellan () is a small town in County Down, in the south-east of Northern Ireland close to the Irish Sea. It is beside Castlewellan Lake and Slievenaslat mountain, southwest of Downpatrick. It lies between the Mourne Mountains and Slieve Croob. It had a population of 2,782 people in the 2011 United Kingdom census, 2011 census. Castlewellan has a wide main street which runs through two main squares lined with chestnut trees. The town was designed by a French architect for the Earl Annesley, Annesley family. The Annesley family did not always own the land as they bought it from the Maginess family, then owners of what is now Castlewellan Christian Conference Centre and Castlewellan Forest Park. Castlewellan is unique within Ireland due to its tree-lined squares both in the old town (upper square) and new town (lower square) as well as its very wide main street. The old market house in the upper square was built in 1764 and now houses the public library. History Evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
