ABSTRACT Aim Historical processes have shaped the Carpathian biogeography, yet ongoing evolutionary forces continue to drive population differentiation. We aimed test whether local adaptation in subendemic Leucanthemum rotundifolium correlates with genetic, morphological and environmental factors, assess how these patterns relate established taxonomic concepts. Location The Mountains, Central Europe. Taxon genus (Asteraceae), a focus on L. . Methods analysed multiple populations of across its distribution. Each individual was characterised using comprehensive set measures encompassing: (1) genetic variation via SNP, Silico‐DArT chloroplast markers; (2) traits, including detailed measurements shape analysis involucral bracts; (3) variables such as climate, soil characteristics, topography indicators human disturbance. first evaluated data collectively distinguish different species align current Next, we examined factors interact within differentiate individuals populations. Results Taxonomically recognised were supported by distinct signatures (particularly SNPs), preferences key traits (notably upper row bracts). At intraspecific level, primarily differentiated (across all markers) factors. In contrast, variability showed no strong spatial signal, though subtle tendencies toward differentiation emerged when interpreted conjunction consistent clustering. Main Conclusions Our findings highlight that taxonomy corresponds closely certain parameters. Within , is strongly reflected divergence, while appear more conservative. Nevertheless, shifts may still track underlying ecological differentiation, revealing complex interplay shaping trajectory this subendemic.
