It isn't hard to understand, but it is hard to convince you if you refuse to understand.
_________________________
I'm not refusing to understand anything, keith. My point is that most of the world associates American Walnut with Eastern Black Walnut. Do a search and that is what you get. You're not getting that the difference is whether or not the "W" is capitalized or not. Of course an English Walnut tree grown in America is American ............by "birth". But, it's not the same as American Walnut, with the capital "W".
Here's an example of one search result.
