The article gives a description of the Carici sempervirentis - Pinetum nigrae association, which grows in steep shady locations in mountainous region of theUpper Kolpa Valley in the Ko~evsko Region (Slovenia). Its character and differencial species are Carex sempervirens, Globularia nudicaulis, Aquilegia nigricans, Adenophora liliifolia and Sesleria kalnikensis. The association is divided into two sub-associations: -salicetosum appendiculatae subass. nova and -gentianetosum symphyandrae subass. nova. A comparison of Slovenian Pinus nigra syntaxa with others in south-eastern Alpine and Dinaric mountain regionswith the analysis of a detailed floristic, phyto-coenological and geo-elemental composition and the analysis of the spectrum of biological formshas shown that despite some similarities it distinctly differs from them floristically and ecologically. The association is a long lasting transition developmental stage of a progressive succession sequence. From floristic and ecological point of view, other compared Pinus nigra syntaxa also differ well from each other, those of the south Dinaric Mountains, which are ranked into the Sorbo umbellatae-Ostryenion carpinifoliae (Fukarek 1969) Accetto 1999 suballiance, at the most.
