Before the recent taxonomical revision, it was divided into two subgenera: Waldsteinia and Comaropsis (Rich. Waldsteinia belongs to the Rosaceae family and inhabits the temperate zone of the Northern Hemisphere. One of the examples can be Waldsteinia Willd., a small genus of herbaceous plants containing only a few species, which was joined to the genus Geum L. In these taxonomic revisions, small groups of related organisms are often considered, as their position on the tree of life is often debatable and sometimes too subjective. Rapid integration of molecular biology approaches into classic botany makes it possible to review the existing phylogenetic relationships based on the differences in DNA sequences. lobata belong to a single maternal lineage, but the observed genetic differences are too small to serve as a convincing argument for species segregation, so their relationships still remain unresolved. maximowicziana) and considered a separate species. ternata aggregate (traditionally including W. maximowicziana is still not fully resolved, we support the point of view that claims it should be separated from the W. geoides (a type species) position on the plastid and nuclear DNA trees, together with the discrepancy between the species morphology and its location on the plastid DNA tree, a hybrid origin was suggested for this species. Hence, Euro-Siberian, Northeast Asian, and North American phylogeographic groups were distinguished, with East Asia having been suggested as the place of Waldsteinia origin. The phylogenetic relationships of Waldsteinia species were better explained by their geographical distribution than their morphology. Phylogenetic analysis based on the joint ITS + trnL-trnF dataset demonstrated Waldsteinia monophyly. We have obtained a phylogenetic reconstruction based on the nuclear (ITS) and plastid ( trnL-trnF) DNA to understand the phylogenetic structure of Waldsteinia and its relationships with other taxa of Geum s.l. According to the latest revisions, Waldsteinia is included in Geum. Waldsteinia is a small plant genus inhabiting the temperate regions of the Northern Hemisphere.
