78 Lester F. Ward first found this tree in the Dismal Swamp in 1887, and believed it to be a form of the 

 Laurel Oak. The latter species and the Water Oak appear to have been generally confused with this 

 species. From the Water Oak it differs in the rhombic shape of its leaves and in its larger acorns with 

 deeper cups, which are rounded, not flat-bottomed, as in the Water Oak, and in its more persistent foliage. 

 It differs from the Laurel Oak in the rhombic shape of its leaves, which are also very much thinner and turn 

 yellow in autumn. 



77 Its chief distinctive characteristic is the broad top-end of the leaves which are often somewhat three- 

 lobed or rounded. 



7! C. S. Sargent (Bot. Gaz., LXV, 451, 1918) states that the one tree now known was found on a street 

 leading to Magnolia Cemetery in Beaumont, Tex.
