3. Leaf Arrangement (Phyllotaxy) Three different leaf arrangements: Alternate (one leaf per node), opposite (two leaves per node) and whorled (three or more leaves per node). A node is the place where one or more leaves are attached along the stem. The area between the nodes is called the internode.
Ash fruits (left: white ash, right: green ash) Click on an image for further information about it. Leaves Ash leaves are pinnately compound. That means that the leaflets are arranged in rows on opposite sides of the central stem (rachis) of the leaf. White and green ash leaves typically have 5 to 9 leaflets, while blue ash typically has 7 to 11 leaflets. There are a number of common tree species that have leaves like this. However, most of them have leaves that are arranged alternately on the twig, whereas ash tree leaves are arranged oppositely on the twig.
