Oncidium, abbreviated as Onc. in the horticultural trade,[2] is a genus that, as of December 2023[update], 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.[3][4] Common names for plants in this genus include dancing-lady orchid[5] and golden shower orchid.
A 2008 molecular phylogenetic study labeled the Oncidium alliance "grossly polyphyletic."[6] In the same year, the American Orchid Society labeled the genus a "dumping ground".[7] A consensus announced in April 2013 resulted in major taxonomic changes to Oncidium, Gomesa, Odontoglossum, Miltonia, and others.[8] Much of this debate and subsequent housekeeping was initiated by significant research for the scientific publication Genera Orchidacearum Volume 5.[9] As a result, much of the information in this article is now deprecated, but still of great value. One significant change is the move of most Brazilian Oncidium with a fused lateral sepal to the genus Gomesa.[7][6] The Royal Horticultural Society system, the World Checklist of Monocots database[10] and the American Orchid Society have updated their databases to reflect most of these changes.
