| Hygrophytes – plants living on highly moistened soils and at high humidity (sedge, cotton grass, rice, reed, marsh marigold, papyrus, etc.) Hygrophytes have devices for intensive transpiration. They have thin leaf blades with constantly open stomata; they have specific “water stomata” through which water is released in a drip-liquid state. Hygrophytes have poorly developed mechanical tissue, cuticle, and epidermis. In the leaf mesophyll, they have large intercellular spaces, and in some species in the roots and stems there may be aerenchyma – tissue that stores air in the intercellular spaces. Hygrophytes are not able to tolerate even a small lack of moisture in the soil and quickly fade.
