Worldwide, there is some agreement that regular edible bananas should be called bananas, while starchy bananas that are usually baked or cooked should be called plátanos or plantains.
Platáno is a Spanish word that originally was not linked to the banana. It was used to describe a small family of trees, the planes or plane trees. These trees are indigenous in the northern hemisphere. The origin of the scientific name of these species, platanos, is Greek: πλατσυός. That word can be traced back to platos (πλατός), which means ‘broad’ or ‘wide’. Now we can easily understand why the Spaniards decided to call the banana shrub platáno; it has very broad leaves.
Carl von Linné (1707 – 1778) or Carolus Linnaeus in his latinized form used the Arabic mauz to describe the family and name it Musa. However, a minority of scholars think that Musa is derived from Antonio Musa (63-14 BC), the physician to Emperor Augustus.
