摘要
通过对大量标本、野外居群的观察分析和文献研究,回顾了淫羊藿属的分类学研究历史,分析了中国淫羊藿属小花类群的重要分类性状及演化趋势,初步提出中国淫羊藿属小花类群的分类系统。结果表明:分布于中国的淫羊藿属小花类群有20种,应以花部形态特征及演化规律为依据划分为4组:1.花瓣扁平型组Sect.Campanulatae;2.花瓣浅兜型组Sect.Gib-bae;3.花瓣囊型组Sect.Sacciferae;4.花瓣具短距组Sect.Calcar。
On the basis of a large amount of specimens, observation of field population and literatures, the taxo- nomic history of Epimedium is reviewed. The important classified character and evolution of small - flowered taxa of Epimedium are analyzed and a new system of classification for small - flowered taxa of Epimedium is proposed. The results show that 20 species of small - flowered taxa of Epimedium in China can be divided into 4 sections according to the character and evolutionary trend of flowers ： 1. Sect. Campanulatae,2. Sect. Gibbae,3. Sect. Sacciferae,4. Sect. Calcar.
