What are the characteristics of wind-pollinated plant flowers?

Wind-pollinated plants have inconspicuous, small flowers collected in inflorescences – ears, panicles, etc. The flowers are inconspicuous, since wind-pollinated plants do not need to attract insects for pollination. Flowers do not have a pleasant smell, nectar. Wind-pollinated plants grow in large clusters so that there is a high probability of pollen from one plant to another. Since the pollen is carried by the wind, the flowers of such plants have long filaments and a long pistil.
