| 摘 要： | 利用扫描电子显微镜对小檗科淫羊截属，３４种及亚种４４个花粉样品进行了观察和研究。该属植物花粉的外壁纹饰有由不规则条纹状突起到穴状，穴网状，再至网状或条网状学化的趋势，其中包括穴由少到多，由小到大；网脊表面具微刺至平坦的演化方向，与形态性状的演化基本一致，具有重要的分类价值。

| Abstract: | Forty-four pollen speciemens from thirty-four species and subspecies or varieties of the genus Epimedium (Berberidaceae) were examined by means of election microscope. The result revealed that the exine ornamentation evoled from irregularly-arranged stiate with small tips to foveolate, foveolate-reticulate, and to reticulate or striato-reticulate type, along with the reticulate tectum from having small tips on it to psilate. Its taxonomic significance among them is discussed. |
