souri. The species is fouml in all parts of the State, although the dis- 

 ti'ibution of the varieties has not been worked out. The habitat of 

 this species is high ground, and only rarely is it fovuid in low ground. 

 It prefers hills, slopes, base of the terraces of streams, and in the 

 northern part of the State gravelly ridges and sandy soil. In all of its 

 range it is usually associated with white and black oak. It is in- 

 fiequent in the southern part of the State but north of the Wabash 

 Eiver it becomes more frequent and in some ]:)laces it becomes common 

 to very common. It is a common tree in Wells County north of the 

 Wabash River and in the northern part of Lagiange C-ounty, and in 

 both places a wide range of forms occur, some of which are not covered 

 L)y the preceding desciiption. No one of our trees offers a better op- 

 jioi'tunity for intensive study than this hickory. 



Remarks. — Text books call this species the small-fruited hiekorj^. 

 It is not connnonly distinguished frf)m the other hickories, but in 

 Wells C'ounfy where it is (ommon the boys call it "Ladies' Hickory."

Dislribiilion. — Southwestern Indiana, south in the Mississippi 

 ^'alley to Louisiana and Texas. Known in Indiana only from one tree
