对我国淫羊藿属经典分类的研究现状进行简要回顾,并对其中存在的问题进行分析。淫羊藿属是分类学上较为特殊和困难的属,类群数量近30年迅速增长,且90%以上的物种为中国特有,但近一半的物种为外国研究者命名(其中Stearn命名了17种),且绝大多数是依据少量栽培个体命名,种间界限模糊不清使复合体大量存在。其根本原因是缺乏足够的野外调查和形态性状统计,对各类群性状变异幅度、变异式样和分类价值研究不够。淫羊藿属存在分种过细问题,根据非间断性状命名的类群可能存在,大量种的“真实身份”还需进一步讨论。未来研究应充分重视并应用“居群”概念,应用现代化的技术软件DELTA进行分类描述。
This paper briefly reviews the research status of Epimedium Classics in China, and analyzes the existing problems. Epimedium is a more taxonomic and more difficult genus. The number of taxa is rapidly increasing in recent 30 years and more than 90% of the species are endemic to China. However, nearly half of the species are named after foreign researchers (among them Stearn named 17 species ), And most of them are based on the name of a small number of cultivated individuals, fuzzy boundaries between species so that a large number of complex exist. The root cause is the lack of sufficient field investigation and morphological traits statistics, and the studies on the variation range, variation pattern and classification value of each group trait are not enough. Epimedium is a sub-species problem, there may be a group named according to non-disruptive traits, a large number of species “real identity ” needs further discussion. Future research should pay full attention to and apply the concept of “population”, and use the modern technology software DELTA to classify and describe.
