Oncidium Heterantha
''Oncidium'', abbreviated as Onc. in the horticultural trade, is a genus that contains about 330 species of orchids from the subtribe Oncidiinae of the orchid family ( Orchidaceae). As presently conceived (May 2014), it is distributed across much of South America, Central America, Mexico and the West Indies, with one species ''(O. ensatum)'' extending into Florida. Common names for plants in this genus include dancing-lady orchid and golden shower orchid. In 2008, Oxfords Annals of Botany labeled the ''Oncidium'' alliance "grossly polyphyletic." The American Orchid Society labeled this genus a "dumping ground."Lindleyana : The scientific journal of the American Orchid Society. December 2008 Pg 20 After DNA testing and much debate, a consensus was announced (April 2013) resulting in major taxonomic changes to ''Oncidium, Gomesa, Odontoglossum, Miltonia,'' and others. Much of this debate and subsequent housekeeping was initiated by significant research for the scientific p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oncidium Altissimum
''Oncidium altissimum'', Wydler's dancing-lady orchid, is a species of orchid native to the West Indies (Cuba, Puerto Rico and the Lesser Antilles), with an 18th-Century citation from Jamaica. This name should not be confused with the illegitimate homonym ''Oncidium altissimum'' Lindl. 1833, now considered a synonym of '' O. baueri'' native to South America. The true ''Oncidium altissimum'' was first described in 1760 by Nicolaus Joseph von Jacquin with the name ''Epidendrum altissimum'', citing Jamaica as the origin of the specimen he was describing . Olof Swartz later transferred the species to ''Oncidium ''Oncidium'', abbreviated as Onc. in the horticultural trade, is a genus that contains about 330 species of orchids from the subtribe Oncidiinae of the orchid family (Orchidaceae).

Deprecated
In several fields, especially computing, deprecation is the discouragement of use of some terminology, feature, design, or practice, typically because it has been superseded or is no longer considered efficient or safe, without completely removing it or prohibiting its use. Typically, deprecated materials are not completely removed to ensure legacy compatibility or back up practice in case new methods are not functional in an odd scenario. It can also imply that a feature, design, or practice will be removed or discontinued entirely in the future. Etymology In general English usage, the infinitive "to deprecate" means "to express disapproval of (something)". It derives from the Latin verb ''deprecari'', meaning "to ward off (a disaster) by prayer". In current technical usage, for one to state that a feature is deprecated is merely a recommendation against using it. It is still possible to produce a program or product without heeding the deprecation. Software While a deprecated so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Column (botany)
The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae. It is derived from the fusion of both male and female parts (stamens and pistil) into a single organ. The top part of the column is formed by the anther, which is covered by an anther cap. This means that the ''style'' and ''stigma'' of the pistil, with the filaments and one or more anthers, are all united. Orchidaceae The stigma sits at the apex of the column in the front but is pointing downwards after resupination (the rotation by 180 degrees before unfolding of the flower). This stigma has the form of a small bowl, the clinandrium, a viscous surface embedding the (generally) single anther. On top of it all is the anther cap. Sometimes there is a small extension or little beak to the median stigma lobe, called rostellum. Column wings may project laterally from the stigma. The column foot is formed by the atta ...

Tolumnia (plant)
''Tolumnia'' (abbreviated ''Tolu.''), is a genus in the family Orchidaceae. Previously known as the "equitant oncidiums," the species were segregated from the mega-genus ''Oncidium'' by Guido Braem in 1986. Dancing-lady orchid is a common name for some species in this genus. Description The plants are small, usually epiphytic, with small or absent pseudobulbs completely covered by leaves, which are triangular or circular in cross section and overlap each other at base to resemble a fan. The inflorescences arise between the leaf base and bear colorful, showy flowers. The labella are large, ornamented by variously shaped calli. The column bears prominent wings flanking the stigma. The genus is primarily native to the Greater Antilles, with a few species extending into Florida, the Lesser Antilles, Mexico, Central America and northern South America (from Colombia to French Guiana).

Psychopsis ''Psychopsis'' is a genus of four known species of orchids native to northern South America, Central America and Trinidad. The genus name is abbreviated ''Pyp.'' in the horticultural trade.Alphabetical List of Standard Abbreviations for Natural and Hybrid Generic Names, Royal Horticultural Society, 2017. https://www.rhs.org.uk/plants/pdfs/plant-registration-forms/orchid-name-abbreviations-list.pdf Description ''Psychopsis'' are epiphytic orchids with laterally crushed cylindrical pseudobulbs from which two fleshy coriaceous leaves appear apically, in their center two floral wands emerge with large golden yellow flowers with purple spots on bands in sepals and on the lip whose edges are forming folds. ''Psychopsis'' very often grows on the trunks and branches of trees. The flowers look like large butterflies with brightly colored bodies (the lip, a modified petal), very long antennae-like petals, and outspread wing-like dappled yellow and brown sepals. The butterfly orchid is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] |
