The Bixaceae are a family of dicotyledonous plants commonly called the achiote family. Under the Cronquist system, the family was traditionally placed in the order Violales. However, newer arrangements move it, with some other families previously in the Violales families, into the Malvales.The Bixaceae include three genera and a total of 25 species, although Cochlospermum is sometimes placed into its own family, Cochlospermaceae.
