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). 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 publication ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).

Oncidiinae
The Oncidiinae is a subtribe within the Orchidaceae that consists of a number of genera that are closely related. This subtribe consists of about 70 genera with over 1000 species, with '' Oncidium'' as its largest genus. These genera consist of a single floral type based on the angle of the attachment of the lip to the column, reflecting pollinator preferences. This has however led to several unreliable results and polyphyletic taxa within '' Oncidium''. These were transferred to ''Gomesa'' and a new genus '' Nohawilliamsia'', has been described for ''Oncidium orthostates'' Most Oncidioid species have well-developed pseudobulbs and conduplicate leaves. It is possible to form hybrids in some instances between multiple genera within the Oncidiinae. These hybrids are often colloquially referred to as "intergenerics." Genera Genera recognized in Chase et al.'s 2015 classification of Orchidaceae: * ''Aspasia'' * ''Brassia'' * '' Caluera'' * ''Capanemia'' * ''Caucaea'' * '' Centro ...

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 Olof Peter Swartz (21 September 1760 – 19 September 1818) was a Swedish botanist and taxonomist. He is best known for his taxonomic work and studies into pteridophytes. Biography Olof Swartz attended the University of Uppsala where he s ... later transferred the species to '' Oncidium'' in 1800.Swartz, Olof. 1800. Kongl. Vetenskaps Academiens Nya Handlingar 21: 240.

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 ... [...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 ... [...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 a ...

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] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Labellum (botany)
In botany, the labellum (or lip) is the part of the flower of an orchid or '' Canna'', or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them. ''Labellum'' (plural: ''labella'') is the Latin diminutive of ''labrum'', meaning lip. The labellum is a modified petal and can be distinguished from the other petals and from the sepals by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct. Bailey, L. H. ''Gentes Herbarum: Canna x orchiodes''. (Ithaca), 1 (3): 120 (1923); Khoshoo, T. N. & Guha, I. ''Origin and Evolution of Cultivated Cannas.'' Vikas Publishing House. In orchids, the labellum is the modified median petal that sits opposite from the fertile anther and usually highly modified from the other perianth segments. It is often united with the column and can be hinged or movable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus '' Brassica'') and radish (genus '' Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A comp ...

Pseudobulb
The pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed heteroblastic and homoblastic respectively. All leaves and inflorescences usually arise from this structure. Pseudobulbs formed from a single internode produce the leaves and inflorescence from the top, while those that are formed from several internodes can possess leaves along its length.Hew, C.S., and J.W.H. Yong. 2004The Physiology of Tropical Orchids in Relation to the Industry.Singapore: World Scientific Publishing Co. pp. 13-15. The modified sheath leaves that appear at the base of a pseudobulb and often enfold all or part of it are usually dry and papery, though in some orchids the sheaths bear leaf blades and the leaves at the pseudobulb's apex are reduced to scales.Dressler, R.L. 1993.

Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Spanning , Florida ranks 22nd in area among the 50 states, and with a population of over 21 million, it is the third-most populous. The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville. Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first k ...
