Plants that grow in water or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content (plants typically found in water habitats).
Plant life capable of growing in wet conditions, such as in water or in soil or other substrate that is periodically saturated with water. The presence of hydrophytic plants is one of the indicators used in wetland identification and delineation.
Plants that have adapted to living in aquatic environments. These plants are also called hydrophytes. In wetlands, hydrophytic species occur where at least the root zone of the plant is seasonally or continually found in saturated or submerged soil.
