Cuttings ofTamarix aphyllawere grown in various concentrations of NaCl. Salt glands on newly developed branches were sectioned and examined, both with the light‐ and with the electron‐microscope. An electron‐dense material appears in cuttings grown in all concentrations of NaCl at the anticlinal walls of the innermost pair of secretory cells and, to some extent, on the surface of the gland above the cuticle. In the glands of cuttings grown in high concentration of NaCl this material also appears in large quantities, not only on top of the gland but also beneath the cuticle at the region of the median anticlinal wall of the outermost pair of secretory cells. The material beneath the cuticle is connected to the electron‐dense material on the outer surface of the cuticle via the secretory pores. It is suggested that this material is of pectic nature and forms a continuous system with the walls and wall protuberances of the secretory cells which are also very rich in pectic substances. As pectic substances absorb solutions easily they may enhance the transport of salt.Many proplastids, vacuoles with simple structure and others with infolded membranes as well as numerous mitochondria were observed in the secretory cells. In the walls between the collecting cells and the innermost secretory cells there are numerous plasmodesmata with characteristically arranged me
