Red Maple (acer Rubrum)
Distinguishing characters: The *bark is smooth and light gray*, like
that of the beech, on the upper branches in older trees, and in
young trees over the whole trunk. Fig. 30. The buds are in clusters,
and the terminal twigs, Fig. 31, are quite red.
Leaf: Whitish underneath with three-pointed lobes. Fig. 32.
Form and size: A medium-sized tree with a narrow, round head.
Range: Eastern North America.
Soil and location: Prefers moist places.
Enemies: Leaf blotches (_Rhytisma acerinum_) which, however, are not
Value for planting: Suitable as a shade tree for suburban streets. Its
rich red leaves in the fall make it attractive for the lawn.
Commercial value: Its wood is heavy, close-grained, and takes a good
polish. Used for furniture and fuel.
Other characters: The _bud_ is small, round, and red. The _flowers_
appear before the leaves are out in the early part of April.

Comparisons: The red maple is apt to be confused with the silver maple,
but the latter can be distinguished by its turned-up twigs and scaly
bark over the whole trunk of the tree, which presents a sharp
contrast to the straight twig and smooth bark of the red maple. The
latter has a bark similar to the beech, but its branches are
_opposite_, while those of the beech are _alternate_.
