Anemophily

• When the pollen grains are transferred from one flower to the another flower through the wind then it is called anemophily and flower is known as anemophilous flower.
• The anemophilous plants produce enormous amount of pollen grains.
• The pollen grains are very small, lightweight and dry (non-sticky).
• Stigma is large often hairy or feathery to easily trap air borne pollen grains and mucilaginous (Sticky).
• They often possess well exposed stamens so that the pollens are easily dispersed into wind currents.
• Yellow clouds of pollens are formed by Pinus tree due to the pollen grains which is called "sulphur Shower".
• Winged pollen grains are found in Pinus.
• Anemophilous flowers are neither attractive nor with fragrance. They do not have nectar glands. Anemophilous flowers are generally unisexual.
• Maximum loss of pollen grains takes place in this type of pollination. It is completely non-directional process.
• Wind pollinated flowers often have a single ovule in each ovary and numerous flowers are packed into an inflorescence e.g. corn cob. The tassels is styles and stigmas which wave in the wind to trap pollen grains.
• Pollination by wind is more common amongst abiotic pollinations.
• Wind pollination is quite common in grasses. e.g. - Gymnosperms, maize (corn), sugarcane, bamboo, coconut, Cannabis, grasses, date palms, papaya.
