What appears to be leaves on some acacia trees are actually modified petioles, the parts of the stem that attach the leaves to the branch. When the petioles form in this manner, they are called phyllodes. The plant may start out with real leaves that change to phyllodes as it matures. Other species have a modified stem called a cladode. On the species that do have true leaves, the leaves are pinnately compound—consisting of rows of leaflets around a central stem.
