× Sophrolaeliocattleya
× ''Sophrolaeliocattleya'' (from ''Sophronitis'', ''Laelia'' and ''Cattleya'', its parent genera) is a Hybrid name, nothogenus of artificial intergeneric orchid Hybrid (biology), hybrids. It is abbreviated as Slc. in the horticultural trade. As of 2008, × ''Sophrolaeliocattleya'' is defunct, with the genus ''Sophronitis'' having been merged into ''Cattleya''. Anatomy, morphology and habit × ''Sophrolaeliocattleya'' often shows the influence of its ''Sophronitis'' parent strongly; its flowers tend to range through yellow-orange to red, they tend to be smaller, and the general habit (biology), habit of the plant tends to be comparatively compact, all characteristics shared with ''Sophronitis''. Etymology and taxonomic history This nothogenus, nothogeneric epithet is derived by putting together the component genera: ''Sophronitis'' (combining form -), ''Laelia'' (combining form -) and ''Cattleya''; it is capitalized and is not italicized because it is a nothogeneric epith ...

× Cattlianthe
× ''Cattlianthe'', abbreviated ''Ctt.'' in the horticultural trade, is the Orchidaceae, orchid nothogenus for intergeneric hybrid grex (horticulture), greges containing at least one ancestor species from each of the two ancestral genera ''Cattleya'' and ''Guarianthe'', and from no other genera. Since orchids in ''Guarianthe'' were placed in ''Cattleya'' before 2003, many orchids in × ''Cattlianthe'' were previously placed directly in ''Cattleya''. Notable hybrids Notable hybrids, known as Grex (horticulture), greges, include the following: * ''Ctt.'' Jewel Box (formerly ''Slc''. Jewel Box), a Hybrid (biology), hybrid cross of ''Guarianthe aurantiaca'' and ''Cattleya'' Anzac. Its bifoliate pseudobulbs are about 4" tall and grow along a horizontal rhizome. A terminal inflorescence is produced from a sheath at the tip of newly matured pseudobulbs. ''Ctt''. Jewel Box averages 4.8 flowers per inflorescence and 9.2 cm (3.6 inches) natural spread.

Hybrid Name
In botanical nomenclature, a 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 if the author considers it necessary (in practice, authors tend to use this option for naturally occurring hybrids), but it is recommended to use parents' names as they are more informative (art. H.10B.1). * 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-alpha ...

× Laeliocatanthe
The multiplication sign (), also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. The symbol is also used in botany, in botanical hybrid names. The form is properly a four-fold rotationally symmetric saltire. The multiplication sign is similar to a lowercase X (). History The earliest known use of the symbol to indicate multiplication appears in an anonymous appendix to the 1618 edition of John Napier's . This appendix has been attributed to William Oughtred, who used the same symbol in his 1631 algebra text, , stating:Multiplication of species .e. unknownsconnects both proposed magnitudes with the symbol 'in' or : or ordinarily without the symbol if the magnitudes be denoted with one letter. Other works have been identified in which crossed diagonals appear in diagrams involving multiplied numbers, such as Robert Recorde's '' The Ground of Arts'' and Oswald Schre ...

× Laeliocattleya
''Laeliocattleya'' is a nothogenus of intergeneric orchid Hybrid (biology), hybrids descended from the parental genera ''Laelia'' and ''Cattleya''. It is abbreviated Lc. in the horticultural trade. Due to the recent decision by the Royal Horticultural Society (the international orchid registration authority) to recognize the reduction of the Brazilian ''Laelia'' species and the entire genus ''Sophronitis'' to synonymy under ''Cattleya'', many hybrids which had previously been described as ''Laeliocattleya'' hybrids are now classified as ''Cattleya'' hybrids (e.g. ''C''. George Cutler). The nothogenus name × ''Sophrolaelia'' (for hybrids between ''Sophronitis'' and ''Laelia'') is now a synonym of × ''Laeliocattleya''. List of grexes * ''Laeliocattleya'' (syn.

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] |

Habit (biology)
Habit, equivalent to habitus in some applications in biology, refers variously to aspects of behaviour or structure, as follows: *In zoology (particularly in ethology), ''habit'' usually refers to aspects of more or less predictable ''behaviour'', instinctive or otherwise, though it also has broader application. ''Habitus'' refers to the characteristic form or morphology of a species. *In botany, the plant habit is the characteristic form in which a given species of plant grows.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Behavior In zoology, ''habit'' (not to be confused with ''habitus'' as described below) usually refers to a specific behavior pattern, either adopted, learned, pathological, innate, or directly related to physiology. For example: * ...the atwas in the ''habit'' of springing upon the oor knockerin order to gain admission... * If these sensitive parrots are ...

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 ...

Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are '' Bulbophyllum'' (2,000 species), '' Epidendrum'' (1,500 species), '' Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes '' Vanilla'' (the genus of the vanilla plant), the type genus '' Orchis'', and many commonly cultivated plants such as '' Phalaenopsis'' and '' Cattleya''.
