| 摘要: |
| 为厘清半蒴苣苔属（Hemiboea C. B. Clarke）内H. esquirolii H. Lév.、合萼半蒴苣苔（H. gamosepala Z. Yu. Li）、卷瓣半蒴苣苔（H. follicularis C. B. Clarke var. retroflexa Yan Liu & Y. S. Huang）3个存疑类群的分类地位，解决该属部分物种界定模糊及分类争议问题，该研究通过原始文献查阅和标本检视，并结合野外调查发现：（1）H. esquirolii作为华南半蒴苣苔（H. follicularis C. B. Clarke）异名的分类处理并不恰当；（2）H. esquirolii与卷瓣半蒴苣苔实为同物异名；（3）合萼半蒴苣苔的主模式标本和等模式标本的植物材料实为贵州半蒴苣苔（H. cavaleriei H. Lév.）的错误鉴定。依据2025年《国际藻类、菌物和植物命名法规（马德里法规）》，我们在此将H. esquirolii恢复为种等级分类单元，H. follicularis var. retroflexa 处理为H. esquirolii的异名，但保持其中文名称——卷瓣半蒴苣苔不变；将合萼半蒴苣苔处理为贵州半蒴苣苔的异名。该研究澄清了半蒴苣苔属3个存疑类群的名实问题，为后续半蒴苣苔属的系统演化研究、物种资源保护与合理利用提供了理论基础。 |

| Abstract: |
| To clarify the taxonomic status of three dubious taxa within Hemiboea C. B. Clarke—namely H. esquirolii H. Lév., H. gamosepala Z. Yu. Li, and H. follicularis C. B. Clarke var. retroflexa Yan Liu & Y. S. Huang—and to resolve issues of ambiguous species delineation and taxonomic controversy within the genus, this study integrated examinations of original literature, specimen collections, and field observations, revealing that: (1) Although H. esquirolii and H. follicularis C. B. Clarke share synchronous phenology and most morphological characters of H. esquirolii fall within the variation range of H. follicularis, H. esquirolii can be distinguished by stable genetic characters. Therefore, the previous taxonomic treatment merging these taxa is not appropriate. (2) H. esquirolii is actually synonymous with H. follicularis var. retroflexa. (3) The type specimens of H. gamosepala contains mixed materials from two species within Hemiboea, and the plants 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 algae, fungi, and plants (Madrid Code) (2025), we hereby reinstate H. esquirolii as an independent specific rank, treat H. follicularis var. retroflexa. Huang as a synonym of H. esquirolii, and treat H. gamosepala as a synonym of H. cavaleriei. This study clarifies the taxonomic relationships among three dubious taxa within Hemiboea, providing a taxonomic foundation for subsequent research into the phylogenetic evolution of the genus, as well as for the conservation and rational utilization of its species resources. |
