Basic Tree Identification: Opposite Leaf Arrangement

Vertical image showing how opposite leaves are attached to a tree's stem. Opposite leaves are across from each other at the same node of a stem, branch, or twig. This leaf arrangement is common to maple, ash, dogwood, and horsechestnut trees. The presence of axillary buds at the node of these two opposite leaves helps confirm this leaf arrangement. This is an image of an ash tree.
