Does anyone recognize these two different leaves?


Well, they are both seedlings, or more correctly, from the same seedling.


Look close as you move along the branch. This tree started out the season with the deeply lobed, first leaves, and in the middle of last season, changed to the much less lobed, second leaves, and continued the rest of the season with the second leaf style. Forgetting for the moment that it is a seedling, how are you going to identify a tree that can change leaves like that?
