Wind pollinated flower e.g. Zea mays (maize) have non-essential whorls such as calyx, corolla, bracts and bracteoles that are not showy. Flowers are devoid of scent and nectar. The tassels represent the stigma and style. Pollen grains are dry, very small sized, non-sticky and unwettable, so that they can be carried by wind to long distances. Stigma is hairy, feathery that catches the wind borne pollens.
