Yes I see what you are talking about.CountryBoy19 said:They appear alternate to me.wood spliter said:I think the leaves look opposite?bsearcey said:The leaves appear to alternate which cancels out ash. Therefore your only left with a few options with a compound leaf like that. That would be walnut or pecan. I don't know if walnuts always produce nuts. Maybe something has happened to them to prevent nut production.
Leaf key for pinnately compound leaves.

Dept. of Forestry. Not a great shot of the leaf, but not the description of the bark. Sounds like yours

Check and see if the leave are opposite or alternately arrange along the branch.
The "leaf" one big bunch of the leaflets that you see. Are you looking at the leaflets being opposite one another on the main stem of the leaf? You need to look where the "leaf" attaches to the branch, see how they alternate?
