Nothogenus
In botanical nomenclature, a Hybrid (biology), hybrid may be given a hybrid name, which is a special kind of botanical name, but there is no requirement that a hybrid name should be created for plants that are believed to be of hybrid origin. The ''International Code of Nomenclature for algae, fungi, and plants'' (ICNafp) provides the following options in dealing with a hybrid: * A hybrid may get a name; this will usually be the option of choice for naturally occurring hybrids. * A hybrid may also be indicated by a formula listing the parents. Such a formula uses the multiplication sign "×" to link the parents. ** "It is usually preferable to place the names or epithets in a formula in alphabetical order. The direction of a cross may be indicated by including the sexual symbols (♀: female; ♂: male) in the formula, or by placing the female parent first. If a non-alphabetical sequence is used, its basis should be clearly indicated." (H.2A.1) * Grex (horticulture), Grex names can b ...

Grex (horticulture)
The term ''grex'' (plural ''greges'' or ''grexes''; abbreviation gx), derived from the Latin language, Latin noun , , meaning 'flock', has been expanded in botanical nomenclature to describe hybrids of orchids, based solely on their parentage. Grex names are one of the three categories of plant names governed by the International Code of Nomenclature for Cultivated Plants; within a grex the ''cultivar group'' category can be used to refer to plants by their shared characteristics (rather than by their parentage), and individual orchid plants can be selected (and propagated) and named as cultivars. Botanical nomenclature of hybrids The horticultural nomenclature of grexes exists within the framework of the botanical nomenclature of hybrid plants. Interspecific hybrids occur in nature, and are treated under the International Code of Nomenclature for algae, fungi, and plants as nothospecies, ('notho' indicating hybrid). They can optionally be given Linnean Binomial nomenclature, bin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
× Sorbopyrus Auricularis
The shipova (× ''Sorbopyrus irregularis'' (Otto von Münchhausen, Münchh.) :de:Clemens Alexander Wimmer, C.A.Wimm.) is a Hybrid (biology), hybrid of the European pear (''Pyrus communis'') and the common whitebeam (''Sorbus aria''). It is a small to medium-sized tree growing to 10–18 m tall (or 4 - 6 m on dwarfing rootstock), with deciduous oval leaf, leaves 7–11 cm long and 5–6 cm broad. The fruit is a pome 2.5–3 cm long; it is edible with a sweet, yellowish flesh, which tastes similar to a Nashi pear. History The hybrid, known as the Bollwiller pear, first arose at Bollwiller in Alsace, France, before 1612, and has mostly been propagated by grafting since then; it is nearly sterile, only rarely producing any viable seeds. Two successful seedling propagations have been named as the cultivar 'Bulbiformis' and as the species ''Pyrus malifolia'', but shipova trees are not widely cultivated. Shipova is the only known species in the nothogenus × ''Sorbopyrus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botanical Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from Alpha taxonomy, taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). History and scope Botanical nomenclature has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hybrid Speciation
Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare. With DNA analysis becoming more accessible in the 1990s, hybrid speciation has been shown to be a somewhat common phenomenon, particularly in plants. In botanical nomenclature, a hybrid species is also called a nothospecies. Hybrid species are by their nature polyphyletic. Ecology A hybrid may occasionally be better fitted to the local environment than the parental lineage, and as such, natural selection may favor these individuals. If reproductive isolation is subsequently achieved, a separate species may arise. Reproductive isolation may be genetic, ecological, behavioral, spatial, or a combination of these. If reproductive isolation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legitimacy (family Law)
Legitimacy, in traditional Western common law, is the status of a child born to parents who are legally married to each other, and of a child conceived before the parents obtain a legal divorce. Conversely, ''illegitimacy'', also known as ''bastardy'', has been the status of a child born outside marriage, such a child being known as a bastard, a love child, a natural child, or illegitimate. In Scots law, the terms natural son and natural daughter bear the same implications. The importance of legitimacy has decreased substantially in Western countries since the sexual revolution of the 1960s and 1970s and the declining influence of conservative Christian churches in family and social life. Births outside marriage now represent a large majority in many countries of Western Europe and the Americas, as well as in many former European colonies. In many Western-influenced cultures, stigma based on parents' marital status, and use of the word ''bastard'', are now widely consider ...

Synonym (botany)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal form ...

Iris Florentina
The identity of the plant first described by Carl Linnaeus as ''Iris florentina'' remains unclear, . In horticulture, it has been treated as a white-flowered variant of ''Iris'' × ''germanica'', under names such as ''Iris germanica'' nothovar. ''florentina'', ''Iris'' × ''germanica'' var. ''florentina'' and ''Iris'' × ''germanica'' 'Florentina'. ''Iris florentina'' has also been treated as the correct name for the true species also known as ''Iris albicans'' Lange. It is cultivated as an ornamental plant in temperate regions almost worldwide and is a rhizomatous perennial from southern Europe, mainly Italy (including the city of Florence) and France. It has a thick violet-scented rhizome, sword-like green or grey-green semi-evergreen leaves, a tall branched stem, and many flowers that are white and tinged or flushed with blue, pale blue, or lavender in spring or summer, and a white and yellow beard. It is also grown to produce orris-root, a scented substance used in perfumes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
