Before you say liquidambar styraciflua, its definitely a Maple... sort of Palmatum-ish...maybe?
It looks incredibly like Sweetgum leaves, but this tree has keys not prickly balls.
I was told by owner that tree came from TxA&M Univ., as a grafted tree, but the grafted portion died and this maple is the rootstock.
This tree (or part of it) has bonsai in its future.
Thanks!
