Pollination by Wind
Among the plants that are pollinated by wind are the grasses not only tying grasses of the meadows, but also wheat and corn and the other grains. The stamens of these plants have long slender filaments so that the anthers wave in the slightest breeze, freeing their pollen. The stigmas of most grasses are like tiny plumes, which catch large quantities of pollen. Many spring-blooming trees such as the birch and the oak are wind pollinated. Most wind-pollinated flowers are not brightly colored and not fragrant.
