We adopted this orphan maple tree that was found in our flower bed last year. It has survived a Winter in the pot and now we are ready to plant it. however, we'd like to know what it is. After searching lots of maple ID websites, we couldn't figure this one out. I've attached photos of the top of the leaf, back of the leaf, the tree, and the bark. Any help you can give would be much appreciated. (It does not match any of the maples currently in our yard). We are in Pennsylvania. Photo 234 is the top of the leaf, 233 is the underside. Many Thanks!
