Technically speaking, a monocot cannot truly be a tree since there is no secondary growth, which is responsible for a dicot’s width (that is, a monocot cannot grow to large heights without growing in width for added support). But Banana “trees” can grow pretty high as far as monocots come (3 meters). This genus is native to tropical Africa and southeast Asia, but is widely cultivated in tropical regions throughout the world. The genus name Musa comes from the Arabic for banana, muz (موز). Bananas are among the most popular fruits in the world, humans and monkeys alike.
