摘要： Seed traits have proven to be an effective taxonomic tool in a variety of plant groups and at different levels of classification. The main objective of this study was to describe and compare the characteristics of seeds from all wild-growing herbaceous peonies in Serbia and to evaluate and test their potential taxonomic significance. Seed samples of Paeonia officinalis subsp. banatica (Rochel) Soo, P. tenuifolia L., P. peregrina Miller, and P. daurica Andrews (15 populations) were collected across the Republic of Serbia and analyzed using light and scanning electron microscopy; 17 seed characters in total were identified, 14 of which were qualitative. The collected data was analyzed using both basic and multivariate statistical methods, focusing on both quantitative and qualitative traits. The outcomes revealed a distinct separation between the species based on both quantitative and quali-tative parameters. The characters that contribute most to discrimination between species are seed length, color, and shape, sutura and hilum shape, and seed surface type. Based on these characters, a determination key was created, which enables easier identification of species. The results greatly contribute to the taxonomy of the genus Paeonia, and these characteristics enable a more accurate diagnosis of each of the examined species.
