Acer spicatum Lam.
Mountain maple is native to southeastern Canada and the northeastern United States.
Identification: Mountain maple is a small tree or shrub, up to 33' (10 m) in height, but usually much smaller, especially at the northern end of its range. The trunk is short, often crooked, and often shrublike. It is found in cool woods, growing in shade or sun. This is easily confused with striped maple—both are found in mountain forests, and both are small trees with three-lobed leaves—but mountain maple is found at higher elevations. To further confuse matters, there is a western species, Acer glabrum, that is also called mountain maple. (See Acer for comparisons.)
