The genus
Oncidium is a spectacular and diverse genus of orchids (Orchidaceae), with 3337 recognized species, and almost inumerable grex hybrids, both intrageneric and intergeneric. The genus does indeed range throughout central and southern Mexico, Central America, and South America, as well as much of the Caribbean. One species (
O. ensatum , or alternatively
O. floridanum) is even native to southern Florida.
The common name, Dancing Ladies, refers to the way the blooms of some species resemble a woman wearing an ornate ball gown with a full skirt. The image in the previous post is a good example of this.
Though many
Oncidium are predominantly yellow, the genus also contains species white, pink, orange, red, and maroon flowers.
Most often, multiple colors are present on the various parts of these complexly structured flowers.
As an example of Oncidium diversity, here is the Pink Bird's Beak Orchid (Oncidium sotoanum, formerly confused with Oncidium ornithorhynchum). This species is native to southern Mexico and Central America.
