Distribution: Italy
A close relative of P. valcuvianensis and P. hirsuta but distinguished genetically (See reference paper). This species is found growing on limestone on the Italian Grigna massif, above Lake Como. In the original description this species was compared with P. daonensis by having less sharply toothed leaf margins and calyx lobes actute, and compared with P. villosa by having smaller leaves and glandular hairs that are not red. Compared with P. hirsuta the calyx lobes are patent with the tube (spreading in hirsuta). This species hybridizes with P. auricula in the wild.
