Dwarf Chinkapin Oak - Quercus prinoides
As often a shrub as it is a tree, this small oak (15 feet) grows throughout much of the East and Midwest from central Oklahoma to Pennsylvania. It is undoubtedly small at least in part from the sterile, dry habitat to which it is relegated. The small trunk is covered with a scaly bark, and the leaves are yellowish-green and coarsely toothed; they may reach six inches in length. The leaves are somewhat pointed at the base and broad above the middle. In spite of the harshness of its habitat this oak produces abundant acorn crops. The nut is enclosed in a cup of hairy scales.
