Vallisneria is a freshwater aquatic plant that uses water as an agent for pollination. Pollination in Vallisneria is epihydriphilous. It is a type of hydrophily which occurs on the surface of the water. In this type of pollination, the female flowers reach the water surface by a long stalk to receive the pollen grains which float on the water surface.
