they have a tolerance for salt water
Like Xerophytes, halophytes also possess
- Succulent leaves and stem
- Thick walled and heavily cutinized epidermis
- Hairy covering and mucilage cells.
- The leaves are reduced to small scaly structures (Casuarinas) or spines (Opuntia)
- The leaves are shed when water is scarce
- Water storage structures develop in the leaves
- They have a thick cuticle and a multiple layered epidermis
- They have long roots, which go in search of water
- The stem becomes green and takes over the function of photosynthesis where the leaves are absent/reduced/shed.
