We established that it grows in a unique community of swards and heaths which usually extends over small surfaces (4–10 m 2 ) and is dominated by herbaceous perennial species (hemicryptophytes) and dwarf shrubs (chamaephytes) with mostly arctic- alpine and south-European montane distribution. This community is explicitly (floristically and ecologically) different from the communities of swards and heaths described in the Julian Alps so far, so we classified it into a new association Pulsatillo vernalis-Dryadetum octopetalae ass. nova (order Rhododendro hirsuti-Ericetalia carneae) and subdivided it into two, floristically and ecologically clearly distinguished subassociations -ericetosum carneae subass. nova and -vaccinietosum subass. nova. i g o r Da k S k o b l e r e t a l .: Nahajališča in rastišča vrste Pulsatilla vernalis…
