编辑点评：功能强大的植物辨识应用，用内置相机拍摄叶子，然后LeafSnap就会帮你识别植物种类。可惜的是，目前数据库内只包括纽约和华盛顿附近的树木种类。下班路上偶遇一朵摇曳的野花，也许你不会介意停下脚步看看它叫什么名字。

　　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, fruits, petioles, seeds, and bark to aid identification. These high-resolution images were created by the conservation organization Finding Species.

　　Leafsnap currently includes trees found in the Northeastern United States and Canada. The inclusion of Canadian trees is through collaboration with the Canadian Wildlife Federation, with support from TD Friends of the Environment Foundation.
