Materials for the ecological-geographical analysis of Kuznetsov Mountain (Samara Region) vascular plants flora

According to the results of the ecological-geographical analysis, the aboriginal fraction of the vascular plant flora of Kuznetsov Mountain (Samara Region) is presented Eurasian (74,8% of species from the composition of the aboriginal fraction), Pluriregional (14,5%) and European (10,7%) geographical elements. The largest number of species have Eurasian (32,2%), European-West Asian (14,4%), Holarctic (12,1%), Euro-Siberian (10,3%), European (8,8%) and European-West Siberian (8,4%) longitude areal types. The latitudinal component of the areal is dominated by plurizonal (36,9% of the natural fraction of the flora), boreal-nemoral (21,5%), forest-steppe (15,4%) and nemoral (12,1%) plant species. The adventive fraction of flora is mainly formed by species of the Mediterranean, the North American (28,3% each of the composition of the adventive fraction) and the Iranian-Turanian (24,5%) origin. The current geographical distribution of a significant part of the adventitious species is associated with Holarctic (30,2%), Eurasian (22,6%), Hemicosmopolitan (17,0%) and European-West Asian (11,3%) areals. The endemic species ( Crataegus volgensis Pojark.) and 8 relict species [ Anemone altaica Fisch. ex C.A. Mey., Bupleurum aureum (Hoffm.) Fisch. ex Hoffm., Laser trilobum (L.) Borkh., Pulmonaria mollis Wulfen ex Hornem., Geranium robertianum L., Caragana frutex (L.) C. Koch, Aconitum septentrionale Koelle, Corydalis solida (L.) Clairv.] have been identified in the flora of the vascular plants of Mountain Kuznetsov. The boundaries of the areals of 7 flora species [ Matteuccia struthiopteris (L.) Todaro, Athyrium filix-femina (L.) Roth, Aconitum septentrionale Koelle, Crataegus volgensis Pojark., Bupleurum aureum (Hoffm.) Fisch. ex Hoffm., Campanula latifolia L., Anemone altaica Fisch. ex C.A. Mey.], represented on Mountain Kuznetsov, pass through the territory of the Samara Region.
