摘　　要：对十字花科岩荠属（Ｃｏｃｈｌｅａｒｉａ）、阴山荠属（Ｙｉｎｓｈａｎｉａ）、泡果荠属（Ｈｉｌｉｅｌａ）、棒毛荠属（Ｃｏｃｈｌｅａｒｉｅｌａ）植物的叶表皮特征进行了扫描电镜观察，结果表明：表皮细胞多为不规则形，气孔主要分布于下表皮，垂周壁上有明显的波状嵴或沟槽状下陷，平周壁上有各种条纹状角质层纹饰。这些微形态特征在属间有明显的类群特异性，又有一定的过渡类型，为岩荠属及近缘属的合理划分提供一定的证据。The studies on epidermal features of leaves in 16 species belong to Cochlearia, Yinshania,Hilliella,Cochleariella were conducted with scanning electron microscopy. The epidermal cells are anomo-shaped, and the stomata are mostly focussed in the low epidermis. Their anticlinal wall have clearly sinuous ridges or sink in and form groove,and the periclinal walls have various ornamentations of cuticles. These micromorphological characteristics are different among the genera and there are crossing ones between Yinshania and Hilliella. This paper will provide some proof for dividing this four genera.
