Mangrove has some unique leaf anatomical features in addition to its morphological characters, which were associated to their adaptation to its saline environments. All the species have thick cuticle and sunken stomata to reduce transpiration. The presence of glandular and non-glandular hairs on the abaxial and adaxial leaf surfaces in some taxa are related to salt secretion of these plants. Numerous water storage tissues occur in the hypodermal or mesophyll tissue of the leaves indicating the modification nature of mangroves in their saline habitat. The presence of terminal tracheids helps with capillary water storage within the leaf. The coriaceous nature of the leaves in some taxa is due to the presence of brachy and astero sclereids with in the mesophyll region.
