OAK WILT: A Threat to Red Oaks by Dr. David L. Roberts
  • Here are two typical leaf specimens from the red oak group, a subgroup of genus (Quercus).  This is a simple (one blade), pinnate (one central vein, the mid-rib, and smaller branching veins) leaf.  Notice how the leaf lobes are bristled, forming pointed ends which classify it to the red oaks species. 
  • An outline shape of these leaves in  black/white. 
  • Also, compare the major difference between the red oaks to the white oak leaf.
