Description

Any of several North American trees of the genus Carya, such as the white hickory tree (Hicoria alba). Hickory trees are found from New Hampshire to Texas. Hickory timber is valued because it is strong, elastic and shock resistant. The reddish brown wood has a straight grain and a fine texture that polishes well. Pecan is one well-known type of hickory. Hickory is used for flooring, tool handles, farm implements, chairs, wheel spokes, golf clubs, and baseball bats. It is also split into thin canes for weaving.
