Anemophilous

Anemophilous, a botanical term signifying pollinated by wind, applied to such plants as hazel, pines, plantains, and grasses, in which the pollen is usually very abundant, small-grained, and smooth, and is carried by wind, often on to a plumose stigma. This is facilitated in some cases by the flowers being produced before the leaves, or by lateral air bladders on the pollen grain.
