title: Taxonomy and nomenclature of the polymorphic European high mountain speciesAndrosace vitaliana(L.) Lapeyr. (Primulaceae).
abstract: Androsace vitaliana(syn.Vitaliana primuliflora; Primulaceae) has been subject to several taxonomic treatments, whose conclusions ranged from a single species with numerous infraspecific taxa to several species usually without infraspecific taxa. Here, following molecular investigation, several taxonomic changes are made. A single species with the following infraspecific taxa is recognized: subsp.vitaliana(Pyrenees), subsp. cinerea (south-western Alps), subsp. lepontina (Pennine Alps), subsp. sesleri (south-eastern Alps), subsp. praetutiana (Apennines) and subsp. assoana (Iberian Peninsula excluding the Pyrenees), the last of which is divided into the four allopatrically distributed varietiesassoana,centriberica,flosjugorumandnevadensis. Contrary to some previous assertions, all taxa are allopatric and, especially for subspp.vitaliana,cinereaandlepontina, where clear diagnostic characters are lacking, they can best be determined by their geographic origin.
