(d) : Anemophily is the pollination by wind. Anemophilous plants are characterized by small flowers, pollens present in large number which are small, dry and light in weight, number of ovules generally reduced in ovary, feathery or brushy stigma to recieve the pollen. All these features are shown by coconut flower. In Vallisneria pollination occurs outside water called epihydrophily. Callistemon (Bottle brush) is pollinated by birds and is an example of ornithophily. Salvia is insect pollinated and is an example of entomophily.
