                 Abstract: To clarify the taxonomic status of three dubious taxa within Hemiboea C. B. Clarke — namely H. esquirolii

                 H. Lév.ꎬ H. gamosepala Z. Yu. Liꎬ and H. follicularis C. B. Clarke var. retroflexa Yan Liu & Y. S. Huangꎬ and to
                 resolve issues of ambiguous species delineation and taxonomic controversy within the genusꎬ this study integrated
                 examinations of original literatureꎬ specimensꎬ and field observationsꎬ revealing that: (1) The previous taxonomic
                 treatment of H. esquirolii as a synonym of H. follicularis C. B. Clarke is not appropriateꎻ (2) H. esquirolii is actually
                 synonymous with H. follicularis var. retroflexaꎻ (3) The type specimens of H. gamosepala contain mixed materials from
                 two species within Hemiboeaꎬ and the plant materials in the holotype and isotype specimens are actually misidentified
                 H. cavaleriei H. Lév. In accordance with the provisions and recommendations of the International Code of Nomenclature
                 for algaeꎬ fungiꎬ and plants (Madrid Code) (2025)ꎬ we hereby reinstate H. esquirolii as an independent specific rankꎬ
                 treat H. gamosepala as a synonym of H. cavalerieiꎬ and treat H. follicularis var. retroflexa as a synonym of H.
                 esquirolii. This study clarifies the taxonomic relationships among three dubious taxa within Hemiboeaꎬ providing a
                 theoretical foundation for subsequent research into the phylogenetic evolution of the genusꎬ as well as for the conservation
                 and rational utilization of its species resources.
