摘要:

为掌握中国淫羊藿属(Epimedium)受威胁物种的地理分布, 提供资源保护和利用的依据, 该研究检索国内外各大数字标本平台数据并实地查阅中国医学科学院药用植物研究所标本馆(IMD)标本。同时, 结合实地调查和文献检索, 系统整理中国淫羊藿属26个受威胁物种(含1变种)的标本信息, 核实其标本鉴定和地理分布, 并调整其濒危等级及其评估标准。共查询到标本428号1 017份, 鉴定正确的仅274号(64.02%) 666份。共19个类群(73.08%)新增《Flora of China》记载之外的分布点, 但有6个种仅分布于模式产地。淫羊藿属受威胁物种丰富度较高的3个省依次为四川(12种)、湖北(7种)和贵州(6种1变种)。对22个类群的濒危等级或评估标准建议调整。其中, 恩施淫羊藿(Epimedium enshiense)、革叶淫羊藿(E. reticulatum)、方氏淫羊藿(E. fangii)和小叶淫羊藿(E. parvifolium)的濒危等级建议上调为极危。天全淫羊藿(E. flavum)、腺毛淫羊藿(E. glandulosopilosum)、直距淫羊藿(E. mikinorii)、光叶淫羊藿(E. sagittatum var. glabratum)、偏斜淫羊藿(E. truncatum)和竹山淫羊藿(E. zhushanense)的濒危等级建议上调为濒危。单叶淫羊藿(E. simplicifolium)和川鄂淫羊藿(E. fargesii)分别由极危和濒危建议下调为易危。另有10个种仅调整评估标准。淫羊藿属植物濒危的主要原因为分布狭窄、生境衰退及种群数减少。淫羊藿属受威胁类群的腊叶标本鉴定错误较突出。该属物种多为狭域分布, 受威胁程度高, 物种多样性保护应足够重视。濒危等级评估是动态过程, 需长期监测和不断更新。

Abstract:

Aims This study aims to understand the geographical distribution of threatened species of genus Epimedium in China, and to provide the basis for resource conservation and utilization.
Methods The data of Chinese Virtual Herbarium (CVH), China National Specimen Information Infrastructure (NSII), the Royal Botanic Garden Edinburgh (E), Royal Botanic Gardens, Kew (K), Muséum National d’Histoire Naturelle (P) and Universitat Wien (WU) were used. The specimens of Herbarium of Institute of Medicinal Botany, Chinese Academy of Medical Sciences (IMD), which is not included in the sharing platform but abundant in Epimedium specimens, were also examined. At the same time, combined with our field investigations and literature review, the specimen information of 25 species and 1 variety of Epimedium in China were systematically collected to verify the specimen identification and geographical distribution, and to update the endangered status and criteria.
Important findings A total of 1 017 specimens of 428 numbers were examined, and only 666 specimens of 274 numbers (64.02%) were correctly identified. Nineteen taxa (73.08%) had found new distribution compared with the recorded of Flora of China. However, 6 species were currently known to be distributed only in the type locality. The three provinces with the highest abundance of threatened species were Sichuan (12 species), Hubei (7 species) and Guizhou (6 species and 1 variety). The endangered status or criteria of 22 taxa were suggested to be adjusted. Epimedium enshiense, E. reticulatum, E. fangii and E. parvifolium were suggested to be upgraded to Critically Endangered (CR). E. flavum, E. glandulosopilosum, E. mikinorii, E. sagittatum var. glabratum, E. truncatum and E. zhushanense were suggested to be upgraded to Endangered (EN). Epimedium simplicifolium and E. fargesii were suggested to be downgraded from Critically Endangered (CR) and Endangered (EN) to Vulnerable (VU), respectively. For another 10 species, the endangered status remained unchanged and only the criteria were adjusted. The main reasons for the endangerment of Epimedium were narrow distribution, habitat decline and population decrease. Errors in the identification of specimens of threatened species of Epimedium were prominent. Most species of this genus were distributed in narrow areas and were highly threatened. Therefore, the protection of species diversity should be paid more attention. The evaluation of endangered status and criteria is a dynamic process that requires long-term monitoring and constant updating.
