Mesophytes are plants which live in places where the conditions of temperature and water supply are not extreme, and they are typically found in temperate forests and grassland. They have a well-developedsystem, and the are generally large and thin, with abundant chlorophyll. The cuticle and epidermis of the leaves are also thin, and the stomata are not specially protected. Most mesophytic areas are occupied by herbaceous and woody plants growing so closely that overcrowding results, and many of the plants are undeveloped and stunted because they are shaded by others. As the result of the competition for space and light, a characteristic adaptation in the form of the climbing habit has arisen.
