Here's a better pic of the leaf
No, that is a pic of a leaf
let. There is a big difference between a leaflet and a leaf. Compound leaves, such as hickories, black locust or ashes, consist of a number of leaflets (3 to 15 mostly, nearly always an odd number). Identification of a species is very difficult with only pics of the bark and leaflets. Post a pic of the leaves: preferably several leaves, attached to a branch, so we can see the arrangement of the leaves on the branch and the appearance of the buds.
