Description

Worldwide, the Oaks (Quercus spp.) consist of 275 to 500 species that can be separated into three groups based on their microanatomy: the Live or Evergreen Oak group, the Red Oak group (Erythrobalanus), and the White Oak group (Leucobalanus). Species within each group look alike microscopically. The word Quercus is the classical Latin name of oaks.

Generally the sapwood of oak is white to very light brown, while the heartwood is light to dark brown in the white oak group and reddish brown in the red oak group.
