Scope note:

Species of maple closely related to sugar maple (A. saccharum), and in some classifications treated as a subspecies; the situation is complicated by the fact that the two species tend to form hybrids. The two species may be distinguished by number of leaf lobes: the black maple has three-lobed leaves and the sugar maple has five-lobed leaves.
