The green, flat, and expanded part of the leaf is called the leaf lamina or leaf blade. The tip of the lamina is known as the apex. The basal part of the leaf by which it is attached to the node of the stem is called a petiole. A petiole is also known as a leaf stalk. It supports the leaf in a plant and also attaches the lamina to the stem. Leaves without petioles are called sessile leaves. An axillary bud is always present at the base of the leaf petiole.
