Abstract Background Styrax , a vital raw material for shipbuilding, construction, perfumes, and drugs, represents the largest most diverse genus in Styracaceae. However, there is relative scarcity of research on particularly evolution genetics. Therefore, this study conducted comparative evolutionary analyses chloroplast genomes five rare species ( S. argentifolius buchananii chrysocarpus finlaysonianus rhytidocarpus ). Results The results indicated that, despite high levels conservation genome structure among these species, specific mutation hotspot regions exist, involving expansion contraction IR region. Additionally, evidence positive selection was detected eight genes atpB ccsA ndhD petA rbcL rpoC1 ycf1 ycf2 ), which may be associated with adaptive response to environmental changes. Phylogenetic analysis revealed conflicts between trees constructed based coding sequences complete several were similar previous phylogenetic studies. Conclusion This underscores importance increasing sample sizes enhance accuracy provides new perspective understanding species. These findings are not only important sustainable use but also provide valuable insights plant ecology within genus.
