A new locality of Allium schoenoprasum subsp. alpinum in the Idrija hills, the first in Slovenia outside the Julian Alps

Abstract

The paper describes the new locality and site of the taxon Allium schoenoprasum subsp. alpinum in the Idrija hills (Kališe, Idrijske Krnice), which is the first locality known in Slovenia outside the Julian Alps. It grows on a wet and acid meadow (Polygalo-Nardetum allietosum alpinae), which is still mown once a year. Its community is floristically very different from the communities in which this taxon grows in the Julian Alps, which was illustrated with the phytosociological table. The occurrence of the subalpine species in the hills on the northern edge of the Dinaric mountains is interpreted as an ice-age remnant.
