摘要
采用了野外观察和光学显微技术对淫羊藿属(Epimedium L.)7种植物的雌蕊及果实的形态结构进行了研究。结果表明:7种植物的心皮数目为1个,胎座类型为边缘胎座,果实类型为蓇葖果。比较了《中国植物志》等文献的记载,订正了文献对7个种"侧膜胎座"或"蒴果"的记述,并对淫羊藿属的相应特征提出观点。
Epimedium L.,a worldwide genus of some 57 species including nearly 50 species in central to southeast China was established by Linnaeus in 1753.China is the modern geographical distribution center of Epimedium L.,and may be the differentiation center.A common problem in phytotaxonomic academia is providing each species with a clear status in the genus.We conducted morphological research on Epimedium L.to deepen and clarify the different descriptions on the characteristics of gynaecium and fruit according Chinese taxonomic literature.Results from field observation and anatomical study showed the placenta type of seven species in Epimedium is marginal placentation and the fruit is follicle.
