These are Acer leaves. Another variety of this tree produces a sap that we enjoy to eat on pancakes. What is it called?
You are correct.
Hmmm... that's not right.
A good way to identify trees is to look at the leaf shape. One thing to notice is whether the leaf has lobes.
Lobes may be arranged either side of a central axis like a feather (pinnately lobed) or have lobes that spread out from a central point, like fingers from a hand (palmately lobed).
