species; excepting its thinner-shelled, generally smaller nut, I 

 have been entirely unable to distinguish characters which will 

 always separate it from the next. Professor Sargent has united 

 it with the Eastern Shagbark, referring to it in the Forestry Re- 



port of the loth Census, p. 133, as '* a form with small, thin 

 shelled nuts." I am very confident that its aUiance is not with 

 H. ovata. The mistake may have arisen from the fact that in 

 the Herbarium of the Philadelphia Academy, a label of NuttalFs 

 has been misplaced and pasted alongside of a flowering twig of 

 H. ovata. But his original description, his authentic fruitmg 

 specimens both at Philadelphia and Kew, and the figure of the 

 plant in his Sylva, prove that its affinities are not with the Shag- 

 barks, but rather as I have placed it

 The size of the nut is given in Gray's Manual (p. 449), at from 



l^ to 2 inches long. While they do actually grow as large as 

 this in the Southern States, the more correct figures for those of 

 New York and the Middle States generally is not more than 

 half these dimensions.

 the leaflets, which, as a general thing, are smaller at maturity 

 than those of any other Northern species.
