Viene descritta una nuova notospecie di Primula scoperta nelle Prealpi Bergamasche, risultato di ibridazione fra P. albenensis Banfi & Ferl., endemica del Monte Alben, del gruppo del Monte Aralalta e della Val d’Ancogno, e P. auricula L. orofita europea, conviventi nell’area geografica in oggetto. L’ibrido presenta caratteri definiti e costanti senza elementi di “sciame ibrido” né segni di introgressione che ne tradiscano una fertilità anche solo parziale. Pertanto, i popolamenti osservati vanno interpretati come risultato di una speciazione ibridogenica inter parentes (notospecie) meritoria di riconoscimento tassonomico.

Abstract
A new hybrid of primrose discovered fifteen years ago in the locality Bivacco La Plana, Pre-Alps of Bergamo, above Chignolo, a hamlet of the municipality of Oneta, later also confirmed for the crest of Mount Alben, always in the same municipality, is here described. The parental species turn out to be Primula albenensis Banfi & Ferl. and P. auricula L., the former endemic to the mountains of Bergamo (Mount Alben, Mount Aralalta group and the Ancogno Valley), the latter a European orophyte, here coexisting often together on limestone faces. The new finding shows constant morphology in its stands, and there is no evidence of either "hybrid swarming" or introgression to exclude the total sterility of the population and this occurrence should be considered result of a process of inter parentes hybrid speciation (nothospecies) deserving of taxonomic recognition.File | Dimensione del file | Formato | |
