Potentilla radiata Lehm., described from northern Iran, also occurs in the Caucasus, Transcaucasia and NE Turkey. It has been reported as P. svanetica Siegfr. & R. Keller, P. sommieri Siegfr. & R. Keller or P. armeniaca Siegfr. ex Th. Wolf by local authors. It was occasionally collected also in the N part of European Russia and in Romania, being described as P. × burduja Prodán & Ţopa, P. × leteae Prodán, P. × moeszii Jáv. ex Prodán, P. × porciusii Prodán and P. gordiaginii Juz. The name P. radiata Lehm., not used previously, has priority over all of the mentioned names. Potentilla radiata is interpreted as a hybrid between P. argentea L. and P. thuringiaca Bernh. ex Link.
