Solution:
Entomophily is pollination by insects. Myrmecophily is pollination by ants. The pollination which takes place on the surface of the water is called epihydrophily. The pollination which takes place inside the water is called hypohydrophily. In Vallisneria, the female flower reaches the surface of the water by the long stalk and the male flowers or pollen grains are released on to the surface of the water. Thus, it shows epihydrophily.
