Identifying Pinnately Compound Leaves
Pinnately compound leaves refer to a leaf that is comprised of two or more leaflets on a common stalk or axis. Additionally, the veins within the leaf's lobes arise from several places along the central vein. You'll most often find these leaves on ash trees, walnut trees, pecan trees, and hickory trees. Let's take a closer look at pinnately compound leaves.
Example of a Pinnately Compound Leaf
This is a really good example of a pinnately compound leaf. It's compound because there are more than two leaflets coming off of the main stalk; and it's pinnate because they're coming off of either side of the main axis. Another feature of pinnately compound leaves are their pinnately veined leaflets, which have numerous veins coming off the main vein of the leaflet.
