Sorbus quernea, a hybridogenous species described in 1996 as an endemic in two places in Prague (Czech Republic), was revised. The revision revealed that S. quernea is taxonomically identical to S. mougeotii, a western-European hybridogenous species with a large distribution area, which was described from the Vosges Mts in France in 1858. Plants from localities given in the protologues of both taxa and from the German Alps, French Alps, the Massif Central and those of unknown origin planted in the Czech Republic, were shown to be taxonomically, karyologically and genetically consistent. At the Prague localities, S. mougeotii (the populations erroneously described as S. quernea) is considered to be an escaped and recently naturalized alien species.
