The article provides the results of a study dealing with pollen release into the atmosphere by 23 species from 21 genera of the Poaceae Barnh family. The species under investigation are the dominant ones in natural plant communities and are used as components in turf plant ^communities and belong to the group of ornamental grasses. Their pollen causes seasonal hay fever (allergic rhinitis), which accounts for the interest in the regularities of its drift. The drift distance is determined by the particles sedimentation velocity and depends on the number of pollen grains they include. The study estimates the cluster composition of pollen particles released into the atmosphere. All species under consideration massively form clusters consisting of two or more grains. Their share was 11,1-50,8%, the share of pollen grains in them was – 21.9-84,0%.
