You are right about the European bilberries being a distinct species. I have used both "strawberry" and "blueberry" as generic names. The European strawberry is also a distinct species, but belonging to the same genus with the American strawberries (Fragaria). The same for the European bilberry and the American blueberry that is the ancestor of the cultivated blueberries. They are different species of the same genus (Vaccinium).
