Oncidium, abbreviated as Onc. in the horticultural trade, is a genus that, as of December 2023, 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.

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.
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.
