Abstract

The article presents the results of floristic and vegetation observations in fifteen rock faces of the eastern half of the pre-Alpine phytogeographical region of Slovenia (9755/ 4; 9756/3,4; 9757/ 3; 9855/ 4; 9857/1; 9955/2, 4). It was ascertained that practically each of the ten rock faces had its own floristic curiosities in addition to numerous common plant species. New localities of the following rare plant species have been found: Carex sempervirens, Carduus crassifolius ssp. glaucus, Campanula thyrsoides ssp. carniolica, Saxifraga petraea, S. crustata, Hieracium villosum, Rhododendron hirsutum. For the first time, phytocoenoses of the associations Arabido alpinae-Saxifragetum petraeae, Jovibarbo hirtae-Saxifragetum crustatae and Campanulo cespitosae-Globularietum cordifoliae are described. It was noticed that the plant taxa found in the rock faces would also be useful as naturally suitable species for the revegetation of rocky roadside slopes on warm sides of the pre-Alpine region of Slovenia.
