The leaf anatomical structure of Limonium aureum was studied by SEM and paraffin method,especially for observing the salt gland location,structure and development.The result indicated that a lot of salt glands was lay in the leaf.The density of salt glands on the abaxial epidermis was slightly higher than that on the adaxialepidermis.And 7～9 epidermal cells radially arranged surrounding thesalt gland.The mature structure of salt gland included 12 cells.There were 4 central secretory cells,and a small hole on the center of saltgland cuticle,where salt released.Outside the secretory cell were the adjacent cells,which were cambered.Behind them were 4 big cells called collecting cell which was close tomesophyll cells.The salt gland of Limonium aureum originaled from a single epidermal cell.After that,it went through 5 stages which were called as single cell stage,2 cell stage,4 cell stage,8 cell stage and 12 cell stage,respectively.
