The mixed forest of fir, spruce, and beech (Piceo-Abietetum Čolić 1965) is an important and widespread plant com- munity on the Balkan Peninsula. Within the Dinarides, it occupies the upper zone of the beech-fir forest belt, establishing a regional belt of vegetation in the Illyrian province. This community occupies significant areas in western and southwestern Serbia where it also creates a regional belt, thus confirming that this part of Serbia belongs to the Illyrian floral-geographical province. This paper compares the floristic composition of the fir-spruce-beech forests in Serbia and Bosnia-Herzegovina in order to determine the differences between the study stands. A total of 29 relevés were analyzed, 17 from the mountain of Lisina (Bosnia-Herzegovina) and 12 from the Pešter plateau (Serbia). Cluster analysis revealed a clear differentiation between the study stands and species in Bosnia-Herzegovina and those in Serbia. The main difference is in the dominant species: Fagus moesiaca (K. Maly) Czecz. in Serbia and Fagus sylvatica L. in Bosnia-Herzegovina. In Bosnia-Herzegovina, the forest grows under conditions of a uniform, maritime and humid climate, while in Serbia it grows under conditions of a continental climate with less rainfall and a strong zoo-anthropogenic impact. Regarding the spectrum of life forms, there are more phanerophytes and geophytes in Bosnia-Herzegovina than in Serbia. On the other hand, the spectrum of floral elements in Serbia is richer in xerophilous, Balkan and sub-Mediterranean floral elements.
