My parents have a Maple Tree and the leaves have these tiny little teeth (pickers, tines..however you say it, lol) that are all the way throughout the leaf, not just on the edges, and they don't know what kind of Maple they have. It turns colors in the fall and the leaf falls off, like other trees. I have tried to do some searching online and just can't come up with anything other than the kind that the teeth are on the outside edges....any ideas?
