A hydathode is a type of tissue in leaves, usually more advanced plant species, that permits the release of water through pores in the epidermis or margin of leaves. They probably evolved from modified stomata. It is involved in guttation, where water is released from the top in order to transport the nutrients in the water from the roots to the leaves.
