Fruit of the genus Musa (family Musaceae), a gigantic herbaceous plant spread by rhizomes, and one of the most important food crops of the world. The banana is consumed extensively throughout the tropics, where it is grown, and is also valued in the temperate zone for its flavour, nutritional value, and constant availability. Hundreds of varieties are cultivated. Perhaps the most important species is the common banana, M. sapientum.

The U.S. imports more bananas than does any other country. See also plantain
