I doubt very seriously this is a hybrid.

I get big variations in leaf form with my tridents, especially if I leaf prune them, or even hard prune their branches. I get leaves with sharply incised cuts and more than three lobes all the time, sometimes on the same branch as "regular" leaves.

I also get alot of variation in fall coloration depending on where they sit in the summer. Full sun exposure can produce alot of oranges and reds in the fall, but this can also vary from autumn to autumn with the weather-- frosts help "set" the reds in the leaves. Early frosts along with dry weather can produced alot of red. Rainy wet autmuns tend to make trees trend toward yellow.
