New app called the LeafSnap for iPhone identifies any leaf, a user takes a picture of, as long as it’s in app’s library. App contains beautiful high-resolution images of leaves, flowers, fruit, petiole, seeds, and bark.

Right now it’s limited to trees native to the Northeastern U.S., but app developers are working on expanding that. The app helps also to learn the names of the trees around. It is a collaboration between Columbia, the University of Maryland, and the Smithsonian Institute.

The app soon will be available for free at Apple Store and Android market.
