Box-elder Maple, or Manitoba Maple have distinct leaves with three noticeable points, one long one at the tip and two smaller points that frame it. When compared to other tree leaves, the Manitoba Maple leaf stands out because it is the only type of maple tree that has compound leaves, and it does not have very deep lobes like many other maple leaves have.
