THUMBNAIL IMAGES OF UPPER PENINSULA HARDWOODS (Deciduous Trees)
These are compound leaves.  A compound leaf consists of several leaflets.  You can tell the difference between a "leaf" and a "leaflet" by looking at where the "leaf" stem attaches.  Leaves are attached to woody twigs.  If a stem attaches to a non-woody "twig", then it is a leaflet.
