Abstract :Aim of study: The white flowers of Osmanthus species have been valued for centuries in medicinal and aromatic applications due to their distinct fragrance and chemical composition. Among the 27 species distributed globally, Osmanthus decorus is the only species endemic to the Caucasus region, found in Russia, Georgia, and Türkiye. O. decorus has a distinct distribution area around Artvin but has not been sufficiently studied at the molecular level regarding its differentiation from other species. Material and method: This study focuses on identifying the molecular differences between Turkish O. decorus samples and other species while constructing their phylogenies. Phylogenetic relationships were analyzed using Bayesian inference with universal DNA barcode markers (nrDNA ITS and cpDNA matK). Main results: The nuclear and chloroplast data were consistent, and all Caucasian Osmanthus specimens clustered into a strongly supported monophyletic group. As a result of the Bayesian analysis, it was determined that O. decorus does not clearly separate from other species within the genus. Research highlights: According to the results of BLAST analysis, it was determined that the samples from Russia and Georgia, which are geographically close to the samples from Türkiye, were 100% matched.
