Hydrophily (water pollination):
- Hydrophily (Gk. hydro=water, philein= to love) is a mode of pollination or transfer of pollen grains from anther to stigma through the agency of water.
- Hydrophily is not very common and occurs only in a few aquatic plants, e.g., Vallisneria, Zostera, Ceratophyllum, Hydrilla, etc.
Epihydrophilly:
- If the pollination happens at the surface of the water, it is known as epihydrophilly.
- Example - Vallisneria
