Annotation.Seed parameters are one of the main characteristics of plants used in taxonomy and a necessary component for plant identification.The morphological and morphometric parameters of seeds are routinely used when describing a particular species.In this article, we present the analysis of the morphometric parameters of Gymnospermium alberti (Regel) Takht., Gymnospermium altaicum (Pall.)Spach, Leontice incerta Pall., and Leontice ewersmannii Bunge (Berberidaceae) growing in different environmental conditions in Kazakhstan.The seed length and width, and the weight of 1000 seeds were the largest in the populations of Leontice ewersmannii, and the smallest, in those of Gymnospermium altaicum.In terms of the shape coefficient, the seeds of Gymnospermium alberti and Leontice ewersmannii were spherical, and those of Gymnospermium altaicum, oblong.Gymnospermium seeds differed from Leontice seeds in the presence of strophioles, the seed coat outgrowths.The variability of morphometric parameters was very low or low in all taxa studied, which indicates the stability of these characters.
