Hydrophily is a fairly uncommon form of pollination whereby pollen is distributed by the flow of waters, particularly in rivers and streams. Pollination syndromes are suites of traits of Flowers aimed at attracting a particular type of Pollinator (Faegri & van der Pijl 1979 Proctor et al Pollination in angiosperms and Gymnosperms is the process that transfers pollen grains, which contain the male Gametes (sperm to where the female Pollen is a fine to coarse powder consisting of microgametophytes ( pollen grains) which produce the male Gametes (sperm cells of Water is a common Chemical substance that is essential for the survival of all known forms of Life.

Hydrophilous species fall into two categories: those that distribute their pollen to the surface of water, and those that distribute it beneath the surface. Surface pollination is rare, and appears to be a transitional phase between wind pollination and true hydrophily, where pollen is completely submerged. See also Pollination syndrome Anemophily or wind pollination is a form of Pollination whereby Pollen is distributed by Wind
Surface hydrophily has been observed in several species of pondweed and waterweed. Potamogeton, commonly called pondweed (note that not all pondweeds are Potamongetons is a Genus of aquatic, mostly freshwater Species exhibiting true submerged hydrophily include Posidonia australis and ribbonweed. Posidonia australis is a species of Seagrass that occurs in the southern waters of Australia.
