Chrysosplenium fallax Koldaeva (Chrysosplenium), a newly recorded species from China

摘要: 报道了在中国吉林省延边市发现的虎耳草科金腰属一中国新记录种——宽卵叶金腰（Chrysosplenium fallaxKoldaeva）。该物种是2021年发表的新物种，原产于俄罗斯远东地区，本次在中国为首次发现。本文结合野外考察和标本研究，对该物种形态学进行了描述，对种子微形态进行了显微观察和测量；利用45个金腰属物种的叶绿体基因组对其进行系统发育分析，初步确认了宽卵叶金腰在属内的系统位置。凭证标本保存于中南民族大学生命科学学院标本馆（HSN）。

Abstract: Chrysosplenium fallaxKoldaeva, recently discovered and collected in Yanji, Jilin Province, represents a newly recorded species of Saxifragaceae in China. This species, native to the Russian Far East, was first described as a new species in 2021. Based on precise field investigations and specimen examination, we provide a comprehensive description ofC. fallaxand its seed micromorphology. Phylogenetic analysis based on chloroplast genomes of 45Chrysospleniumspecies confirmed the systematic position ofC. fallaxinChrysosplenium. Voucher specimens were deposited in the Herbarium of South-Central Minzu University (HSN).
