Users of Leafsnap will not only be learning about the trees in their communities and on their hikes—they will also be contributing to science.

These scientists will use the information to map and monitor population growth and decline of trees nationwide.

The visual recognition algorithms developed by Columbia University and the University of Maryland are key to Leafsnap. The best matches are then ranked and returned to the user for final verification. The algorithms and software were developed by Columbia and the University of Maryland, and the Smithsonian supervised the identification and collection of leaves needed to create the image library used for the visual recognition in Leafsnap.

This means that each plant node only has one leaf growing from it. Examples of trees with alternate leaves include oak trees, sycamore, mulberry, birch , hickory, and willow. Whorled leaves radiate from a single point and surround the stem. The third type of leaf arrangement that is found on some trees is whorled leaves. Whorled leaves grow in a similar way to opposite leaves. However, instead of having just 2 leaves in an opposite arrangement, there are 3 or more leaves growing from each node on stems with whorled leaves.

Simple leaves have single leaf blade. In the photo: maple leaf. Another way to identify types of trees by leave is if they have simple leaves or compound leaves. These terms refer to the number of leaves that grow on the petiole.

The petiole is the small thin stalk that is attached to the stem and the leaf blade lamina. Foliage on trees and plants that is made up of simple leaves only have a single blade growing on the stalk. So, a simple leaf just has one blade on each petiole. Simple leaves can grow in alternate arrangements or opposite arrangements on the stem.

Examples of deciduous trees with simple leaves include maple trees, sycamore trees , elm trees , and oak trees. Compound leaf consists of several leaflets joined to a single stem. Compound leaves are when there are a number of leaflets growing on one leaf stalk petiole. You can think of this as a number of small leaves that grow together to form a complete leaf. It can be tricky to know if the leaf you have in your hand is a simple leaf or compound leaf.

If there is a node, then you have a simple leaf, whereas a lack of node indicates it is a compound leaf. Examples of trees with compound leaves include ash trees, walnut trees , hickory trees , and horse chestnut trees. There are a number of types of compound leaves, and knowing about them can help make tree identification easier. Types of compound leaves. From left to right: pinnate leaves, palmate leaves and double pinnate leaves. Trees that have pinnate leaves mean that the leaflets on the compound leaf grow in each side along the length of the petiole like a feather arrangement.

Sometimes these types of leaves called pinnately compound leaves. Palmate leaves have a number of leaflets growing at the end of the leaf stalk. These compound leaves usually look like the shape of a hand with a palm and fingers. That is why they are called palmate leaves. Trees that grow palmate leaves include horse chestnut and buckeye trees. Trees with bipinnate leaves have leaves that resemble fern leaves. You will notice in pictures of double pinnate leaves that the compound leaves are made up of a number of secondary stems that have leaflets growing in an opposite arrangement.

Some examples of trees with bipinnate leaves are honey locust trees, the Texas redbud, and Kentucky Coffee trees. You can identify a tree by its leaf shape. From left to right: unlobed leaf, lobed leaf and toothed leaf.
