Dombeya of L'Héritier de Brutelle is a synonym of Tourrettia (Bignoniaceae). Dombeya of Lamarck is a synonym of Araucaria.

Dombeya is a flowering plant genus. Traditionally included in the family Sterculiaceae, it is included in the expanded Malvaceae in the APG and most subsequent systematics. These plants are known by a number of vernacular names which sometimes, misleadingly, allude to the superficial similarity of flowering Dombeya to pears or hydrangeas (which are unrelated). Therefore, the genus as a whole is often simply called dombeyas. The generic name commemorates Joseph Dombey (1742–1794), a French botanist and explorer in South America, involved in the notorious Dombey affair, embroiling scientists and governments of France, Spain, and Britain for more than two years.
