maple is very similar in all respects to
sugar maple, and thus is often misidentified as sugar maple. The key
differences separating these two species are black maple's wider and
drooping leaves, longer leaf stalk (petiole), and waxy coating on
twigs greater than two years old. Black maple, like sugar maple, is
an important species for sawtimber, veneer, maple syrup, and fuel
- on young trees, dark gray in color, close, smooth, and firm, becoming
furrowed into long irregular plates lifting along one edge.
- slender, shining, and warmly brown, the color of maple sugar. The
current years twig is identical to sugar maple, but the older
sections of twigs often have a waxy coating that may peel in strips
from the twig.
Winter buds -
conical, sharp-pointed, and brown in color, the terminal
buds much larger than the lateral buds.
- simple, opposite, often 4 inches or
more long and fully as wide, from 3 to 5 shallow lobes with wide-spaced coarse teeth,
dark green in color above, paler below; the clefts are rounded at
the base. Leaf edge is smooth between the points. The leaf stalk (petiole)
is typically greater in length than the leaf blade.
- maple keys (samaras), in short clusters, ripening in September.
Samaras are paired with the seeds joining each other in a straight
line, but the wings are separated by about 60 degrees.
