The Oncidium Alliance is a large group of about 69 genera and 1,600 species stretching from the southern tip of Florida and northern Mexico throughout the Caribbean and Central America to southern Peru, Bolivia, and northern Argentina.
DNA analyses have led to the lumping of a number of former genera into Oncidium, making it now the largest genus in the Alliance with about 520 species. The genera now considered to belong to Oncidium are Odontoglossum, Sigmatostalix, Cochlioda, Symphyglossum, Mexicoa, Miltonioides, Solenidiopsis, Chamaeleorchids, Collare-stuartense and Heteranthocidium.
