Abstract： Epimedium (Berberidaceae) is a hot and difficult topic in taxonomy, and its taxa have been published and revised frequently. In order to more clearly understand the variation of Epimedium, this paper systematically sorted out the important characters of Epimedium on the basis of consulting the research results and specimens, combined with the field investigation and analysis of the research group. The petal pattern is the most important basis for the taxonomy of Epimedium, but it is not absolutely stable, and there may be abundant variations in petal morphology within the species. The color of petals, the color of anthers, and even the size of flowers should not be used as the main basis for classification at least in some taxa. The rhizome type (compact or long creeping) is a useful taxonomic character in most taxa, but it should be based on extensive investigations. There are abundant variations in most taxa on the number and arrangement of leaves on flowering stem, which is difficult to be applied in practice. The variation of non-glandular hair characteristics is very complex and varies, so they should not be used as a key basis for species identification. The plants of genus Epimedium are generally shorter after cultivation, which suggests that it is necessary to conduct survey and morphological observation in natural habitats to understand the morphological characteristics of species. The genus Epimedium in China is still in active evolution, and its morphological variation is complicated. Therefore, cautious should be taken in species identification and resource utilization.
