''Oncidium'', abbreviated as Onc. in the horticultural trade, is a genus that contains about 330 species of orchids from the subtribe

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 ...

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

As a result, much of the information in this article is now deprecated, but still of great value.

Gomesa ''Gomesa'' is a genus of flowering plants from the orchid family, Orchidaceae. It contains about 80–100 species, all native to South America. The genus is abbreviated as ''Gom''.Olof Swartz in 1800 with the orchid ''Oncidium altissimum'', which has become the type species. Its name is derived from the Greek word ὀγκος, ''onkos'', meaning "swelling". This refers to the callus at the lower lip. Most species in the genus are epiphytes (growing on other plants), although some are lithophytes (growing on rocks) or terrestrials (growing in soil). They are widespread from northern Mexico, the

s with small flowers and a dominant lip. They are mostly golden yellow with or without reddish-brown barring, but some are brown or yellowish-brown. Other Oncidium species have white and pink blooms, while some even have startling, deep red colors in their flowers. * Another group has extremely small pseudobulbs and stiff, erect, solitary

leaves A leaf (plural, : leaves) is any of the principal appendages of a vascular plant plant stem, stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", wh ...

. These cylindrical leaves act as a water reserve. They have long racemes with yellow flowers that seem to fan out at the top. Sizes of these orchids can vary from miniature plants of a couple of centimetres to giants with 30 cm-long leaves and racemes of more than one metre long. These species, known as the Mule-Ears, are now classed as '' Psychopsis''. * Formerly there was a third group, called the Variegata or equitant oncidiums. They have no pseudobulbs, giving fan-shaped shoots of less than 15 cm, with triangular section leaves. These oval, broad and spongy leaves act as storage organs. Their flowers are most complicated with exquisite colors. The sepals are somewhat fleshy. The petals and the lip are membranaceous. These orchids are now classified as '' Tolumnia''. ''Cyrtochilum'' is another genus that many ''Oncidium'' species have recently been reclassified into; ''Cyrtochilum'' species have extremely long, winding inflorescences that can sometimes reach 20' or more, curled petals that result in three-pointed blooms, and rambling growth habits in which each new pseudobulb appears on top of the old one. ''Oncidium'' species are characterised by the following properties : * presence of

s at the base of the pseudobulbs. The flowers come in shades of yellow, red, white and pink. The petals are often ruffled on the edges, as is the lip. The lip is enormous, partially blocking the small petals and sepals. Some ''Oncidium'' orchids are very long : ''Oncidum altissimum'' and ''Oncidium baueri'' can grow to a height of 5 m, while ''Oncidum sarcodes'' can reach 3 m. They are known as 'spray orchids' among some florists. They are very varied and are easily hybridised with ''Odontoglossum''. Together with other closely related genera (''Miltonia'', ''Cuitlauzina'', ''Miltoniopsis'', ''Osmoglossum'', ''Leochilus'', ''Comparettia'', ''Cyrtochilum'', ''Odontoglossum'', ''Tolumnia'', ''Rhynchostele'' ormerly ''Lemboglossum'' ''Psychopsis'', etc.) they form the Oncidium alliance. Some of the best Oncidium alliance hybrids originate from ''Oncidium tigrinum'' and ''Oncidium incurvum'', when crossed with Odontoglossums, although hybridization possibilities of this group of orchids are endless, and there are literally hundreds of thousands of excellent hybrids in the Oncidium alliance.
