Leafsnap

Leafsnap is the first in a series of electronic field guides being developed by researchers from Columbia University, the University of Maryland, and the Smithsonian Institution. This free mobile app uses visual recognition software to help identify tree species from photographs of their leaves.

Leafsnap contains beautiful high-resolution images of leaves, flowers, fruit, petiole, seeds, and bark. Leafsnap currently includes the trees of the Northeast and will soon grow to include the trees of the entire continental United States.

This website shows the tree species included in Leafsnap, the collections of its users, and the team of research volunteers working to produce it."

A good tool for leaf identification, but take the picture with a white background.

Technical Remarks:

Device must have a camera.

I don't teach biology, but I do keep this app on my iPhone and enjoy using it when I'm out walking. It's so comprehensive (i.e., has so many possibilities to offer) that it can be a little difficult to use, but it has helped me identify a number of trees about which I had been wondering.
