Pollen size varies extensively among angiosperm species and partially reflects evolutionary adaptation of each species to the pollination and fertilization environment. Size of uninuclear microspores in Aesculus parviflora was analyzed and compared with the size of microspores in Aesculus hippocastanum, Aesculus carnea, and Aesculus flava. The microspores came from closed flower buds of different size (3, 4, and 5 mm) isolated from lower (female flowers), middle (bisexual flowers), and upper (male flowers) segments of inflorescences. Aesculus parviflora had smaller microspores than Aesculus carnea and Aesculus flava, but larger microspores than Aesculus hippocastanum. All analyzed microspores showed bimodal distribution in all investigated species of the genus Aesculus
