Although one usually thinks of flowering plants being pollinated by specific pollinators, rye grass is a wind-pollinated, flowering plant. The flowers produced by rye grass are tiny and inconspicuous as they do not need to attract pollinators in order to transfer their pollen to other plants. The flowers do contain both long, slender anthers (male) and feathery stigmas (female). The male parts of the flowers must produce copious amounts of light pollen that can easily be carried by the wind to the stigmas of flowers of other rye grass plants. Other wind pollinated plants also produce a lot of pollen. This is why many people get hay fever when these plants are at their peak pollen production. The pollen count reported on the news, to which these plants are huge contributors, it is often much higher on dry, sunny days than rainy days. This is because the rain helps to wash away many of the pollen grains from the air.
