Mammee apple was ignored in Belize because everyone insisted that they already had it... "big fruit, brown skin, orange inside, yah, we call it mammee sapote" they would say, and you couldn't convince them that mammee apple is a totally different fruit. Same problem in reverse in Dominica. (they have mammee apple but not mammee sapote) Perhaps with the invention of the smart phone, they will soon be convinced that a person can have 2 mammees.
