walnut, exa&Iy corresponds with the characters 

 Linnaeus has given of Juglans ; the second, com- 

 prehends several species of what the inhabitants call 

 Hickery-trees. In the flowers of the latter I never 

 found more than four square anthers, and I leave it 

 to others to decide whether on this account they 

 ought to be separated into a new genus. The 

 species I observed are the following : 



A. I. Juglans nigra L. Universally known by 

 the name of the black walnut, and so well described 

 and figured by Wangenheim, that any addition 

 would be fuperfluous. It flowers here in the 

 beginning of May, having twenty or more square^ 

 anthers and two pistils. The buds are axillary in 

 the Spring, but during Summer appear above the 

 axils. The nut is in most cases perfectly round, 

 but sometimes oblong; without any concomitant 

 difference in the tree.

 well known by the name of white walnut or butter- 

 nut. The description and figure of Wangenheim are 

 very accurate. I have no doubt but that this is
