Oncidium
''Oncidium'', abbreviated as Onc. in the horticultural trade, is a genus that, , contains about 340 species of orchids from the subtribe Oncidiinae of the orchid family Orchidaceae. It is distributed across tropical and subtropical America from Mexico, Central America and the West Indies to northern Argentina, with one species (''O. ensatum'') extending into Florida. Common names for plants in this genus include dancing-lady orchid and golden shower orchid. A 2008 molecular phylogenetic study labeled the ''Oncidium'' alliance "grossly polyphyletic." In the same year, the American Orchid Society labeled the genus a "dumping ground".Lindleyana : The scientific journal of the American Orchid Society. December 2008 Pg 20 A consensus announced in April 2013 resulted 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 publicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odontoglossum
''Odontoglossum'', first named in 1816 by Karl Sigismund Kunth, is a formerly accepted genus of orchids that is now regarded as a synonym of '' Oncidium''. Several hundred species have previously been placed in ''Odontoglossum''. The scientific name of the genus is derived from the Greek words ''odon'' (tooth) and ''glossa'' (tongue), referring to the two tooth-like calluses on the base of the lip. Species formerly placed in this genus are cool to cold growing orchids to be found on open spots in the humid cloud forest at higher elevations from Central- and West South America to Guyana, with most species around the northern Andes. The abbreviation for this genus is ''Odm''. in the horticultural trade. Many of the species formerly placed in the genus are in great demand with orchid lovers because of their spectacular and flamboyant flowers. Description Most species formerly placed in the genus are sympodial epiphytes, or rarely terrestrials. The pseudobulbs are compact with l ...

Miltonia
''Miltonia'', abbreviated Milt. in the horticultural trade, is an orchid genus comprising twelve epiphyte species and eight natural hybrids. The miltonias are exclusively inhabitants of Brazil, except for one species whose range extends from Brazil into the northeast of Argentina and the east of Paraguay. The genus of ''Miltonia'' was established by John Lindley in 1837, when he described its type species, ''Miltonia spectabilis''. Formerly many more species were attributed to ''Miltonia'', however, beginning in 1978, the miltonias from Central America and from cooler areas of northwest South America have been moved to other genera, including Miltoniopsis and Oncidium, and these changes are still in the process of being accepted by the horticultural trade. ''Miltonia'' species have large and long lasting flowers, often in multifloral inflorescences. This fact, allied to being species that are easy to grow and to identify, make them a favorite of orchid collectors all over the wor ...

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, but also studied orchids, mosses and lichens.

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 Labellum (botany), lip to the Column (botany), 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 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 (plant), Aspasia'' * ''Brassia'' * ''Caluera'' * ...

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''. Moreover, since the introduction of tropical species into cu ... [...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. Distribution 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). 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. Pollination Species in the genus are pollinated by oil-collecting bees o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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 rumored to have started the Orchidelirium, European "Orchidmania" of the 19th century. Very little is known about pollination in ''Psychopsis''. Despite that the flowers are commonly likened to butterflies, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. 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 or ebracteolate. Variants Some bracts are brightly coloured which aid in the attraction of 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 palea (upper bract), while each spikelet (group of florets) has a further pair o ...

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 th ...
