Interpretation of selected species and nothospecies Polygala names published from Central Europe

Selected names of species and hybrids of the genus Polygala described from Central Europe are typified and/or discussed . Polygala x skrivanekii Podpěra is shown to represent a hybrid of the P. amarella x P. comosa parentage, and should be used as a correct name for what has been called P. x beckhausiana Borbáas. The name P. vilhelmii Podpěra represents a synonym of P. comosa. The other names discussed are P. x persimilis Beck (= P. amara s. I.), P. montana Opiz (= P. vulgaris), P mori Brittinger ex Opiz and P moriana Brittinger (both synonymous with P. comosa), and P. reticulata K. B. Presl (probably a form of P vulgaris).
