As we discussed in concept

Wind as an Agent of Pollination -

Wind pollination also requires that the pollen grains are light and non-sticky so that they can be transported in wind currents. They often possess well-exposed stamens so that the pollens are easily dispersed into wind currents. Stigma is large and often-feathery to easily trap air-borne pollen grains. They have a single ovule in each ovary and numerous flowers packed into an inflorescence.

- wherein

E.g., corn cob - the tassels are actually the stigma and style which wave in the wind to trap pollen grains.

 Wind-pollinated plants do not invest in resources that attract pollinating organisms, such as showy flowers, nectar, and scent. Instead, they produce larger quantities of light, dry pollen from small, plain flowers that can be carried on the wind.
