The single oak, scientifically known as quercus imbricaria, is a deciduous tree of the red oak group native to the Midwest and southern southern regions of North America.
The leaves are alternate, oval or ovate, with a wedge or rounded base, a pointed or rounded apex, and sometimes or completely wavy margins.
The wood is pale reddish brown, resembling light sapwood. Coarse-grained, hard, and heavy; used for roof shingles and sometimes in construction.
In the past, this wood was important for making the shingles that gave it its name.
