Hyperhydric intumescences on the stems of Sambucus nigra arise in places where the stem lenticels are immersed in water. The hyperhydric tissue develops through the transformation of the multilayered phelloderm, the parenchyma of the cortex. endodermis and pericycle. The phellogen loses its meristematic properties and is either incorporated into the developing hyperhydric tissue or crushed. The succesive stages of hyperhydric changes which depend on the intense growth of cells and on the ability to devide acquired by them are presented
