I personally haven't heard of any and I would think if there was any they would have been discussed at one time or another on this forum. Try doing a search. If you struggle with ID'ing maples then mark your trees in the summer or during foliage season when you have the leaves to look at. The only non maple around that has leaves similar to maples in this area are sicamores which are easily identified by their whitish gray splotchy trunks.
