Anemophily - Cross-pollination
It is also commonly referred to as wind pollination, i.e., the pollen grains are carried through wind currents. To ensure good pollination the anemophilous plants produce astronomical number of small, dry, light and smooth pollen grains that are released preferably on warm and dry days. Flowers in such plants are unisexual with reduced sepals and petals so as to effectively position the long and feathery stigma for pollen interception. Stamens have long filaments and are exposed to facilitate convenient pollen dispersal, Palms, grasses, millets, bamboos are common examples.
