木鱼坪淫羊藿Epimedium franchetii Stearn被认为狭域分布于湖北神农架和贵州贵阳，在花期开展的箭叶淫羊藿E．sagittatum （Sieb．et Zucc．） Maxim野外调查中发现，原本记载为箭叶淫羊藿的部分居群经鉴定为木鱼坪淫羊藿，为江西和湖南的新分布。导致这种鉴定错误的主要原因有：1）花部特征对淫羊藿属物种鉴定极其关键，但该属腊叶标本，尤其是早期标本，多缺乏花部特征。2）淫羊藿属植物花期较短，多数物种尚未开展花期的野外调查。因此，淫羊藿属的分类学研究应尽量以花期的居群为对象。木鱼坪淫羊藿的新分布记录扩充了其分布范围和生境需求，对淫羊藿属系统地理与区系研究和资源利用具有重要意义。

Epimedium franchetii Stearn ( Berberidaceae ) ,a species native to Shonnongia Forest of Hubei and Guiyang of Guizhou,was discovered in Jiangxi and Hunan Provinces .These populations have previously been considered as E.sagittatum ( Sieb.et Zucc.) Maxim.The main reasons for this misclassification were:1) Floral characters of the genus Epimedium are most important for its taxonomy .However ,these features are often lacking in most herbarium specimens due to the fact that the Epimedium species have very short flowering peri-od.2) Most species are lack of field investigation ,especially that during the full-bloom stage.Therefore,the au-thers suggest that plant taxonomists should use the populations during flower season in their plant taxonomy , which can not only provide fundamental data for its classification , but also conduce to understanding plant a-daptability and probe into its evolution mechanism .The discovery of E.franchetii in Jiangxi and Hunan Prov-inces would provide the foundation for the study of resource utilization and phylogeography of Epimedium.
