From Flora of Indiana (1940) by Charles C. Deam

This is a hybrid between Quercus marilandica and Quercus velutina. I found a single tree on a sandy ridge on the farm of Frank Plass about 2 miles north of Decker or just northwest of the Vollmer Siding of the Chicago & Eastern Illinois Railroad in Knox County. Seed of this tree were generously distributed in 1933 to the larger arboretums of the United States.
