Anemophily

[2] They freely expel a myriad of these pollen grains, and only a small percentage of them ends up captured by the female floral structures on wind-pollinated plants.

[2] These stamens are exposed to wind currents and also have large, feathery stigma to easily trap airborne pollen grains.

[citation needed] Anemophily is an adaptation that helps to separate the male and female reproductive systems of a single plant, reducing the effects of inbreeding.

[citation needed] Anemophily is adaptively beneficial because it promotes outcrossing and thus the avoidance of inbreeding depression that can occur due to the expression of recessive deleterious mutations in inbred progeny plants.

[9] The nature of how species of Poaceae grasses flower results in an increase in the time that the allergenic pollen circulates through the air, which is not favorable to people who are hypersensitive to it.
