The veins of a leaf can be arranged in three different ways. In pinnate leaves the veins all branch off the main vein which runs the length of the leaf. In palmate leaves the veins radiate outward from the base of the leaf like fingers spreading out from the palm of a hand. In parallel-veined leaves, the veins all run parallel from the base of the leaf to the tip. Most leaves have a petiole or a central stalk by which they are attached to the stem. Sessile leaves have no central stalk and are attached directly to the stem. Learn more about Botany.
