Orchidaceae is the largest family of the flowering plants (Angiospermae). Its name is derived from the genus Orchis.

880 genera and nearly 22,000 accepted species, but the exact number is unknown (perhaps as many as 25,000) because of taxonomic disputes. The number of orchid species equals about four times the number of mammal species, or more than twice the number of bird species. It also encompasses about 6–11% of all seed plants. About 800 new orchid species are added each year.

The largest genera are:
Bulbophyllum (2,000 species)
Epidendrum (1,500 species)
Dendrobium (1,400 species)
Pleurothallis (1,000 species)

The family also includes the Vanilla (the genus of the vanilla plant), Orchis (type genus) and many commonly cultivated plants like some Phalaenopsis or Cattleya.
Moreover, since the introduction of tropical species in the 19th century, horticulturists have more than 100,000 hybrids and cultivars.
