Hmm, seems so, though a different Guinea! Very interesting:
> Guineos (pronounced [ɡiˈneos]) usually refers to an unripe banana. The term guineo is sometimes used in reference to its ripened counterpart: the yellow (ripened) banana. Etymology of the word Guineo comes from Guinea, a country in the west of Africa, as it is one of the places from which bananas originate.
Super interesting. Reminded me that in Cuba there's a type of banana they call "guineo". I wonder if it's at all related to its origin.
