New findings about the distribution and sites of Pulmonaria stiriaca Kerner in the Bela krajina region (Slovenia)

In this paper the author informs us about the distribution and new sites of Pulmonaria stiriaca Kerner in the Bela krajina region. These are the southernmost sites in Slovenia and at the same time southernmost within the boundaries of its total distribution. In Bela krajina this species grows on the following association sites: Aconito variegati-Quercetum roboris, Epimedioalpini-Quercetum roboris, Querco-Carpinetum var. geogr. Epimedium alpinum, Hedero-Fagetum var. geogr. Epimedium alpinum and Pseudostellario-Carpinetum, where it builds subassociations - pulmonarietosum stiriacae. It is most abundant in the central forested areas of Bela krajina on Quaternary and Pleistocene deposits, where it indicates moderately acid to very acid and at the same time fresh to humid soil. Outside the above-mentioned area Pulmonaria officinalis predominates
