Some examples of trees with lobed leaves include oak trees and maple trees. The space or indentation between two lobes is called sinus. The clefts or indentations between the lobes can be deep or shallow depending on the type of tree. These leaf blades are made up of earlobe-like shapes, but they form a single leaf. The most easily identifiable type of tree leaf is the lobed variety. Lobed leaves can have rounded tips like the white oak leaf (left) or pointed tips like maple leaf (right) Some examples of trees with bipinnate leaves are honey locust trees, the Texas redbud, and Kentucky Coffee trees. 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. Trees with bipinnate leaves have leaves that resemble fern leaves. Trees that grow palmate leaves include horse chestnut and buckeye trees. That is why they are called palmate leaves. These compound leaves usually look like the shape of a hand with a palm and fingers. Palmate leaves have a number of leaflets growing at the end of the leaf stalk. Sometimes these types of leaves called pinnately compound leaves.Įxamples of pinnate leaves are found on trees such as walnut, ash, pecan, and hickory trees. 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.

From left to right: pinnate leaves, palmate leaves and double pinnate leaves Pinnate leaves (compound) The way that leaves grow on stems is called phyllotaxis in botanical terms.

Types of Tree Leaves with Pictures for Easy Identificationīefore looking at how to tell apart species of trees by the shape of their leaves, let’s look at how leaves grow on stems. Knowing the terms of how leaves are identified (called leaf morphology) is a great way to learn how to identify many trees and plants. These are all different ways to identify tree species by their leaves. You may notice in some pictures of leaves and stems that some leaves grow opposite each other and some are arranged in an alternate pattern. When trying to identify a tree by its leaves, you can also notice the venation patterns on the leaf as well as its color and size.Īnother clue as to the tree species is by looking at how the leaves are arranged on the stem. Also, the margins of these leaves can be smooth, serrated, notched, or lobed. Ovate-shaped tree leaves can be rounded, elongated, or taper to a point. There is much more to identifying tree leaves than just by their shape. The leaf shapes mentioned in this identification guide also apply to other plants such as flowers, shrubs, and bushes. In this article, you will learn about leaf identification and how to recognize the different parts and structures of tree leaves. Evergreen coniferous trees have leaves that look like needles or clusters of scales. Some deciduous trees have tree leaves that are heart, ovoid, rounded, lanceolate, and triangular shapes. It is possible to identify leaves by their shape, edging, size and patterns. Knowing how to identify tree leaves can help to know which trees are growing in woodlands, forests, or parks.
