These plants grow in moist habitats and well-aerated soils. They prefer soil and air of moderate humidity but fail to swive in areas with water-logged soils or ovetabundance of salts. In some respects they stand in between the hydrophytes and xerophytes. Broad leaved plants growing in wet depressions, along lakes and rivers are mesophytes. In general, mesophytes have welldeveloped root system. Stems are generally aerial, solid andfreely branched. Mesophytes may show temporary wilting during noon hours.
