Red Oak (quercus Rubra)

Distinguishing characters: The *bark* is perpendicularly fissured into

long, _smooth, light gray strips_ giving the trunk a characteristic

*pillar effect* as in Figs. 61 and 94. It has the straightest trunk

of all the oaks. The leaves possess _more lobes_ than the leaves of

any of the other species of the black oak group, see Fig. 62. The

acorns, the largest among the oaks, are semispherical with the cups

extremely shallow. The buds are large and sharp pointed, but not as

large as those of the black oak. They also have a few fine hairs on

their scales, but are not nearly as downy as those of the Black oak.

Form and size: The red oak is the largest of the oaks and among the

largest of the trees in the northern forests. It has a straight

trunk, free from branches to a higher point than in the white oak,

see Fig. 94. The branches are less twisted and emerge at sharper

angles than do those of the white oak.

Range: It grows all over Eastern North America and reaches north farther

than any of the other oaks.

Soil and location: It is less fastidious in its soil and moisture

requirements than the other oaks and therefore grows in a great

variety of soils. It requires plenty of light.

Enemies: Like most of the other oaks, this species is comparatively free

from insects and disease.

Value for planting: The red oak grows faster and adapts itself better to

poor soil conditions than any of the other oaks and is therefore

easy to plant and easy to find in the nurseries. It makes an

excellent street tree, is equally desirable for the lawn and is

hardly surpassed for woodland planting.

Commercial value: The wood is hard and strong but coarse grained, and is

used for construction timber, interior finish and furniture. It is

inferior to white oak where strength and durability are required.
