Localities and sites of the neglected umbellifer Physospermum verticillatum (Apiaceae) on Mt. Slavnik in southwestern Slovenia / Nahajališča in rastišča prezrte kobulnice Physospermum verticillatum (Apiaceae) na Slavniku v jugozahodni Sloveniji

On the shady (northern) slopes of Mt. Slavnik (Slavnik mountains, Cicarija, SW Slovenia) we identified Physospermum verticillatum (Apiaceae), a species whose northernmost known sites in its entire distribution area had until then been in the Croatian part of Cicarija near the border with Slovenia (Žbevnica near Dane). It occurs mainly in beech stands from the association Seslerio autumnalis-Fagetum, frequently in smaller gaps, on forest edges and road banks, where it occurs in fringe communities (Calamintho grandiflorae-Physospermetum verticillatinom. prov.), at elevations spanning 800 m to 1000 m. The plants are vital, most of them develop flowers and fruit. Although it is justified to assume that it may occur elsewhere in the Slovenian part of Cicarija, we propose it be classified in the Red List as rare.

Raste predvsem v bukovih sestojih iz asociacije Seslerio autumnalis-Fagetum, pogosto v manjsih vrzelih, tudi na gozdnem robu in cestni brežini, tam v robnih združbah (Calamintho grandiflorae-Physospermetum verticillatinom. prov.), na nadmorski visini od 800 m do 1000 m. Rastline so vitalne, vecinoma cvetijo in plodijo. Kljub temu in upraviceni domnevi, da v slovenskem delu Cicarije lahko raste tudi drugod, jo predlagamo kot redko za uvrstitev na rdeci seznam.
