The foliar epidermal anatomical characteristics of the two endemic Apiaceae species of Korea Bupleurum latissimum Nakai and Dystaenia takesimana (Nakai) Kitag. were investigated. The taxonomically important characteristics of these two species were identified and described to help understand their classical taxonomy. Scanning electron microscopy (SEM) was used to observe the anatomical characteristics of the studied species in detail. The comparative foliar epidermal anatomical characteristics were observed in the present research for the two-endemic species. Some of the most important foliar epidermal anatomical characteristics were observed to distinguish them, including the epidermal cell shape and size, stomata type, and trichomes shape and size. SEM provided sufficient evidence to distinguish the study species. The foliar epidermal anatomical characteristics provide sufficient information to differentiate these two species from their closely related taxa. RESEARCH HIGHLIGHTS: Apiaceae species endemic to Ulleungdo and Dokdo Islands exhibit unique foliar epidermal anatomical characteristics that can be used for taxonomic identification and classification. This study contributes to the documentation of the plant diversity of Ulleungdo and Dokdo Islands, and highlights the need for further research on the biogeography and conservation of these endemic plant species.
研究了韩国两种特有伞形科植物——宽叶柴胡（Nakai）和大独活（Nakai）的叶表皮解剖特征。为了帮助理解它们的经典分类学，确定并描述了这两个物种的分类学上重要的特征。扫描电子显微镜（SEM）用于详细观察研究物种的解剖特征。本研究观察了两种特有物种的比较叶表皮解剖特征。观察到一些最重要的叶表皮解剖特征来区分它们，包括表皮细胞形状和大小、气孔类型和毛状体形状和大小。SEM 提供了足够的证据来区分研究物种。叶表皮解剖特征提供了足够的信息来区分这两个物种与其密切相关的类群。研究亮点：独岛和郁陵岛特有的伞形科物种表现出独特的叶表皮解剖特征，可用于分类鉴定。本研究有助于记录独岛和郁陵岛的植物多样性，并强调需要进一步研究这些特有植物物种的生物地理学和保护。
