中文摘要：

使用扫描电子显微镜对中国28种卫矛属植物的叶表皮细胞进行观察,观察对象包括细胞界限、细胞形状、垂周壁样式、角质膜形态。结果表明,叶表皮细胞形态特征在属内存在多种类型,荚迷卫矛、隐刺卫矛等13种的叶上、下表皮细胞形态具有差别,不支持经典分类学中属下5个组的划分,亲缘关系相近的种通常具有同类型的叶表皮细胞形态特征,支持蒙自卫矛、刺猬卫矛作为独立的种存在。

英文摘要：

The leaf epidermal cells of 28 species of Euonymus in China were observed by scanning electron microscopy （SEM）, and the observed objects contain cell boundary, shape of cells, pattern of anticlinal wall and cutieular membrane morphology. The results revealed that there were various types exist in the leaf epidermal cells of Euonymus. Adaxial and abaxial epidermal cells are different among 13 species such as E. viburnoides and E. chuii. The classical taxonomic treatment as five sections of Euonymus is not supported by this research. Affinitive species usually possess same type on the leaf epidermal cells. E. mengzeanus and E. hystrix were supported as independent specie.
