The anatomy of salt excretory structures was studied in 22 dicotyledonous and monocotyledonous halophytic
species; 13 of which were not previously investigated. The material was selected to represent obligate and
facultative, and succulent and non- succulent halophytes. Structural variations led to their re- naming and
classification. For more precise naming it was believed that one should differentiate between ‘glands' that have
no ontogenic relation to the epidermis and the epidermal appendages, and convinced by this, the excretory
structures were classified into three types and two sub-types. It was also concluded that the presence of such
structures in facultative halophytes, where the concerned stress factor (salinity) is absent, makes it a hereditary
character resulting in an adaptive capacity for salt tolerance. Ectodesmata were recorded in the outer periclinal
walls of the epidermal cells in some species and were considered to be another mechanism for salt excretion.
