摘要: 利用扫描电子显微镜对独行菜属9种植物种子的种皮微形态进行了研究,结果表明独行菜属种皮微形态可划分为4种类型;结果支持将独行菜属划分为3个组的观点;北美独行菜在种皮纹饰上与其它类群差别较大,并结合子叶缘倚胚根的特征将其另立一新组——子叶缘倚组Sect. Accumbentum F. Z. Li, J. Q. Zheng & Z. Y. Sun , sect. nov.

Abstract: The micromorphological characters of seed coats that 9 species of Lepidium from China was examined by scanning electron microscope. The results showed that in micromorphological characters may be delimitated four types and Lepidium is delimitated three sections. But L. virginicum L. is obviously different from others of Lepidium in micromorphological characters of seed coats. Again, through the characters of accumbent, L. virginicum L. should be built a new section——Sect. Accumbentum F. Z. Li, J. Q. Zheng & Z. Y. Sun, sect. nov.

Key words: Lepidium, seed coats, micromorphological character
