 leaflets all of which are large and pubes- 

 cent and possess a distinct resinous 

 odor. 



Form and size: A tall tree with 

 a broad spreading head. 



Range: Eastern North America. 

 Soil and location: The mockernut 

 hickory grows on a great variety of 

 soils, l)ut prefers one which is rich and 

 well-drained. 



Enemies: The same as for the 

 shagbark hickory.

 monly planted. 

 Commercial value: The wood is similar to that of the 

 shagl:)ark hickory and is put to the same uses.

 ered with a shell thicker than that of the shagbark. The
