I found this pretty spiffy site. Its a site where you can ID your tree by finding your leaf. The concept of the site is that it asks you does your leaf have so and so things on it and does it have a simple shape. Then it takes you to a more narrowed down category of leaves then you can click on the one that looks like your leaf and then it tells your the tree, history and other info that helps. I usually use a combo of sites: this one is the leaf ID:
Leaf ID!
And this one to read up on how to care for that type of tree.

Its really helpful. Hope that this helps others that need to ID a tree.
Good Luck!
