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. 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.
Melhania is a genus of small shrubs or herbaceous plants. Traditionally included in the family Sterculiaceae, it is included in the expanded Malvaceae in the APG and most subsequent systematics. The genus is named for Mount Melhan in Yemen.
