Solution:

Hydrophily refers to pollination by means of water. Water pollinated flowers are colourless, small, without nectar and fragrance. The pollen grains are light but covered with wax in order to prevent from wetting.
Hydrophilous species are of two categories: plants that distribute their pollen to the surface of water, eg- Vallisneria's male flower and plants that distribute it beneath the surface. e.g. seagrasses.
