Crataegus × Ariifolia
''Crataegus × ariifolia'' is an ornamental hybrid hawthorn that is used in horticulture. Its name refers to a similarity of its leaves to the genus ''Aria'' ('' Sorbus aria''). Taxonomy The name of this hybrid was originally spelled ''C. ariaefolia'', but this should always be corrected to ''C. ariifolia'' according to article 60.8 of the International Code of Botanical Nomenclature The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all tho .... One of the parents of the hybrid was given as '' C. oxyacantha'' (an invalid name), which probably means '' C. laevigata''. References ariifolia {{crataegus-stub ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Horticulture
Horticulture (from ) is the art and science of growing fruits, vegetables, flowers, trees, shrubs and ornamental plants. Horticulture is commonly associated with the more professional and technical aspects of plant cultivation on a smaller and more controlled scale than agronomy. There are various divisions of horticulture because plants are grown for a variety of purposes. These divisions include, but are not limited to: propagation, arboriculture, landscaping, floriculture and turf maintenance. For each of these, there are various professions, aspects, tools used and associated challenges -- each requiring highly specialized skills and knowledge on the part of the horticulturist. Typically, horticulture is characterized as the ornamental, small-scale and non-industrial cultivation of plants; horticulture is distinct from gardening by its emphasis on scientific methods, plant breeding, and technical cultivation practices, while gardening, even at a professional level, tends ...

Sorbus Aria
''Aria edulis'', the whitebeam or common whitebeam, is a species of deciduous tree in the family ''Rosaceae''. The tree often forms new shoots around the trunk. Typically compact and domed, the plant has a few upswept branches and the leaves have an almost-white underside. The hermaphrodite cream-white flowers appear in May, are insect pollinated, and go on to produce scarlet berries, which are often eaten by birds. It is native to most of Europe as well as North Africa (Algeria, Morocco, Tunisia) and temperate Asia ( Eastern Turkey, Armenia, Georgia). It generally favours dry limestone and chalk soils. The cultivars ''A. edulis'' 'Lutescens', with very whitish-green early leaves, and ''A. edulis'' 'Majestica', with large leaves, have both gained the Royal Horticultural Society's Award of Garden Merit. The berries are edible when overripe ( bletted). File:Weilburg - Tiergarten - Mehlbeere.jpg, Tree References aria In music, an aria (, ; : , ; ''arias'' in common ...

International Code Of Botanical Nomenclature
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. For fungi the ''Code'' was revised by the ''San Juan Chapter F'' in 2018. The 2025 edition of ICBN, the '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crataegus Oxyacantha
The name ''Crataegus oxyacantha'' L. has been rejected as being of uncertain application, but is sometimes still used. Taxonomy Linnaeus introduced the name ''Crataegus oxyacantha'' for a species of Northern European hawthorn and the name gradually became used for several similar species, which were assumed to be the same, particularly the Midland hawthorn '' C. laevigata'' and the common hawthorn '' C. monogyna''. In 1946, Dandy showed that Linnaeus had actually observed and described a single-styled species similar to the common hawthorn, and the Midland hawthorn was effectively a later discovery. However, Byatt showed that confusion over the true identity of ''C. oxyacantha'' remained, and the name was formally rejected as ambiguous by the International Botanical Congress International Botanical Congress (IBC) is an international meeting of Botany, botanists in all scientific fields, authorized by the International Association of Botanical and Mycological Societies (IABMS) a ...

Crataegus Laevigata
''Crataegus laevigata'', known as the Midland hawthorn, English hawthorn, woodland hawthorn, or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain (where it is typically found in ancient woodland and old hedgerows) and Spain, east to Romania and Ukraine. The species name is sometimes spelt ''C. levigata'', but the original orthography is ''C. lævigata''. Description It is a large shrub or small tree growing to or rarely to tall, with a dense crown. The leaves are long and broad, with two or three shallow, forward-pointing lobes on each side of the leaf. The hermaphrodite flowers are produced in corymbs of 6 to 12, each flower with five white or pale pink petals and two or sometimes three styles. They are pollinated by insects. The fruit is a dark red pome diameter, slightly broader than long, containing two or three nutlets. It flowers in May to June (UK) in rather lax clusters. The flowers are usually white, but can be pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
