Wind pollinated plants are very important, and are used to make a huge proportion of the staple foods we eat, such as bread, pastry for pies, cornflakes and so on. Insects and wind can pollinate flowers. Wind is another good agent of pollination.

Of the 250000 species of flowering plants only 10% (25000) are wind-pollinated. The male flowers possess long filament so as to expose the anther to wind. Though wind pollinated, sugar maple is also attractive to pollen-spreading insects such as bees. List of Wind-Pollinated Trees. Examples of plants pollinated by wind are maize and grass. Many pollinator species also rely on wind‐pollinated plants for development sites for pollen‐feeding larvae, e.g. These flowers are unisexual, dull coloured, and without scent and nectar. Pine trees produce large amounts of pollen which is dispersed by the wind. The chance of self-pollination, high by the very nature of wind pollination, is minimized by the fact that many species are dioecious or (like hazel) have separate male and female flowers on each plant.
