Shortly after the chemical stimulation of the digestive glands of Dionaea muscipula discontinuities form in the cuticle bounding the outer walls of the head cells of the gland complex. Such discontinuities can be demonstrated directly by TEM and indirectly by a stimulationdependent increase in the capacity of the glands to absorb vital stains. Once formed, these cuticular gaps remain throughout the life time of the glands. The motive force for cuticular gap formation is shown to be the outwardly directed pressure potential difference between the gland complex and the external medium. The results are discussed with respect to the secretion of digestive enzymes, the absorption of the products of digestion and the penetration of secretion elicitors into the gland complex from the trap lumen before the onset of secretion. © 1983 Springer-Verlag.
