red oak (Quercus spp.; BEECH FAMILY [Fagaceae]) Wisconsin members of the RED OAK group have pointed, bristle-tipped lobes, although species outside our range may be merely toothed or even entire. Acorns of the red oak group generally take 2 years to mature, are bitter, and their shells are hairy inside. Examples: northern red oak, which occurs in hardwood forests throughout the state; black oak, which is abundant in SW Wisconsin; and northern pin oak, which occupies some of the driest wooded sites in Portage County.
