White oak, common white oak, fork-leaf white oak, ridge white oak, stave oak, stone oak, tannerís oak.
A tree that is usually 60 to 80 feet in height, but sometimes reaches 150 feet. The bark is a light ashy gray, variable in appearance--from loosely attached plates on young trees to narrow, rounded ridges with deep fissures on old trees. The smooth thin leaves, which are 5 to 9 inches long, have short stems and are usually divided into 7 to 9 smooth, rounded lobes.
March to May.
Widely distributed in hardwood forests of the eastern United States.
Inner bark, at any time; bark form older trees should be collected in spring.
The pollen is reportedly allergenic. Because the bark contains tannins, it is used as an astringent and antiseptic. In Appalachia, a bark tea is used to treat burns and sore mouth. A chartreuse dye is obtained from the bark.
