Distribution. Northwestern Indiana and southern Wisconsin 

 west to eastern Iowa and southeastern Minnesota. In Indiana it 

 has been reported from Lake County only. Specimens taken near 

 Liverpool, Lake County, by Rev. E. J. Hill, are in the Deam herbar- 

 ium. In its range it has been commonly mistaken for the pin oak 

 {Quercus palustris) which it closely resembles. 



Commonly found on dry or upland ground, although it grows in 

 moist or wet soils. Of the bristle tipped oaks, it is most frequently 

 associated with the red and scarlet oaks.
