Distribution: In the subtropical regions of the Old World and introduced to the tropical regions of the New World.

 

Economic Uses: The family is the source of the cultivated banana, which supports some West Indian and Caribbean economies, as well as the plantain, which is grown as a food source throughout the tropics. A hemp-like fiber can be obtained from the stems of some species.

Defining Features of Interest: The family is arborescent and gains its height from an overlapping of the leaf bases or petioles. This is termed a 'pseudostem' and is not 'wood'. The plants are perennial and can regrow after cutting from a massive corm. The stems also contain a milky juice.

Fossil Evidence: No known fossil record.
