the same with Juglans oblonga of Miller ; but 

 whether Linnaeus has considered it as a variety 

 of I. nigra only, or whether it be J. cinerea of this 

 naturaliff., I am unable to decide. It is easily dis-

 of its leaf stalks and nut shells. The small buds 

 are (as in the foregoing species ) simple and axil- 

 lary in the Spring, but during Summer there issue 

 others above the axils. On account of its medicinal

 number of the leaflets varies very much; I have counted from IS to 17 

 on the leaves of one and the same tree.
