I find this acer today and have no idea of which species it could be. Someone has an idea ? To make it clearer, I cut the 5 parts of the multifoliate leaf on the second picture. Thank you
I don't think so. If you look closer to the samaras shape on the first post of this thread, you'll seed the angle between the 2 samaras which is characteristic of platanoïdes. Macrophyllum samaras are more narrow as you can see here And I have already seen macrophyllum leaves and they are really bigger than these leaves (even if it's not obvious on these photos).
