logoMSu   OAK WILT: A Threat to Red Oaks by Dr. David L. Roberts

  • The white oak, subgroup of genus (Quercus) leaf is identified as a simple (one blade), pinnate, evenly spaced, and rounded leaf lobes.  The leaf on the left has much shallower lobes than the one on the right, with its fiddle shape and large terminal lobe.  This demonstrates the broad variation in white oak leaf shapes, but remember the major identity key to tell the difference between oak leaves is by knowing the rounded leaf lobes belong to white oaks.
  • black/white  outline of the above leaf shapes is shown on this page. 
  • Also, compare the difference between the white oaks to the  red oak leaf.
