Abstract

Aquatic plants that float on the water surface occupy a distinctive habitat that requires particular adaptation. Furthermore, since they are not affected by water depth, they are not limited to a particular zone in the hydrosere but may occur wherever there is sufficient free water. Classically, however, surface-floating plants tend to dominate the offshore margins of the littoral vegetation continuum in those situations where they are not removed by wind or current.
