Thought it would be helpful to have a thread for methods of identifying an unknown tree. I'll start with leaves. Often one goes to a tree id website and gets tangled in the jargon because they use similar terms to describe the veins, the edges, etc.. Here is a nice chart that details the terms used to describe a leaf.

Please add your favorite website for tree id by leaf, bark, wood, etc..
