Hydrophily (Water Pollination):
(Gk, Hydro = water and Philein = to love)
Hydrophily takes place only in few aquatic plants. Hydrophily is of two kinds: hypohydrophily and epihydrophily.
Hypohydrophily is a true hydrophily that occurs beneath the surface of water. It occurs in completely submerged plants and their pollen grains are water borne. Example: Zostera marina, Ceratophyllum, and so on.
a. Ceratophyllum desnersum:
In Ceratophyllum desnersum (that is, a submerged fresh water plant), the male flower bears 30 to 45 stamens. The mature anthers break at the base, mount to the surface of water and dehisce there. The liberated pollen germinates and sinks in water. While sinking, they come in contact with stigma of female flowers to produce pollination.
b. Zostera marina:
In Zostera marina, the pollen grains are elongated (up to 2,500 mm), like needle and without exine. They have similar specific gravity as that of water; thus float beneath the surface of water. Whenever they reach the stigma, they oil about it and germinate.
