The Scientific name for a white apple tree would be an orchid's crab apple tree. I know that it says crab apple tree but it's not a crab apple, the white apple actually has seeds the shape of crab eyes so, the apple was name after a crustacean.
the scientific name of an apple is Mauls domestic. Although Mauls domestic was not always the scientific name, apples were named Paras mauls, in 1753. The name was later changed to what it is known today in 1803.
