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 SloveniaV prispevku so prikazani izsledki opazovanj rastlinstva in rastja v petnajstihostenjih vzhodne polovice predalpskega sveta Slovenije (9755/ 4; 9756/3,4; 9757/ 3; 9855/ 4; 9857/1; 9955/2, 4). Ugotovljeno je, da ima skoraj vsako ostenje svoje floristične posebnosti in številne skupne rastlinske vrste. Med njimi imajo nova nahajališča redke rastlinske vrste Carex sempervirens, Carduus crassifolius ssp. glaucus, Campanula thyrsoides ssp. carniolica, Saxifraga petraea, S. crustata, Hieracium villosum, Rhododendron hirsutum. Prvič smo opisali fitocenoze asociacij Arabido alpinae-Saxifragetum petraeae, Jovibarbo hirtae-Saxifragetum crustatae in Campanulo cespitosae-Globularietum cordifoliae. Seznam opaženih rastlinskih vrst v ostenjih je hkrati širok naravni izbor taksonov za ozelenjevanje skalnatih cestnih brežin v toplejših legah predalpskega svetaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
