When youâre trying to identify a tree, looking at the leaves or needles can be a big help. If tree foliage is a leaf, then youâre probably dealing with a hardwood or decidious tree that can be one of dozens of species that make up a hardwood forest. To figure out which of these trees youâre looking at, take a look at the treeâs leaf, and match it up to the types of leaves identified below.
If you need to start over return to the Tree Key Start Page.
1. Trees With a Simple Leaf
Does your tree have a leaf that is simple (one blade attached to a stalk or petiole)? If yes, go to lobed and unlobed leaves...
OR
2. Trees With a Compound Leaf
Does your tree have a leaf with secondary leaves, called leaflets, borne on a single stalk attached to a twig? If yes, go to compound leaves...
