FIGURE 2 in Taxonomic position and circumscription of Cardamine barbaraeoides (Brassicaceae), a systematically challenging taxon from the Balkan Peninsula
FIGURE 2. Principal component analysis of individuals of Cardamine barbaraeoides from the Lakmos Mts, C. amara subsp. amara (am. am.), C. amara subsp. balcanica (am. balc.), C. amara subsp. opicii (am. op.), C. acris subsp. acris (ac. acris), C. acris subsp. pindicola (ac. pind.), C. acris subsp. vardousiae (ac. var.), and C. raphanifolia, based on nine morphological characters and ten ratios. Prediction ellipses define the regions where any new independent observations from the respective taxa will fall with the probability of 95%.
