Is this a hackberry tree?
This is a young tree and I've not noticed any berries on it. Also, the top branches have alternating leaves, I didn't even notice until I took this picture that the leaves were opposing in the picture.
If it's not hackberry, what could it be? I have American elm and slippery elm and I don't think it's either of those, the leaves are pretty smooth for an elm ... but I am an amateur at tree identification.
Thanks for the help ...
