%X The leaf epidermises of 15 species of <em>Leymus</em> were examined under the light microscope.It was found that these micromorphological differences shown by the lower epidermis may be applied to dividing the Chinese <em>Leymus</em> species into three groups.And in accordance with the external characteristics of each group, these three groups should separately belong to sect.<em>Leymus</em>, sect.<em>Aphanoneuron</em> and sect.<em>Anisopyrum</em> which were described by our predecessors.Moreover, according to the variation trends of leaf epidermal characters, the relationships among three Chinese sections were analysed as well.The results show that sect.<em>Leymus</em> is the most primitive and sect.<em>Anisopyrum</em> is the most advanced among three sections, whereas sect.<em>Aphanoneuron</em> lies between the above two sections;sect.<em>Anisopyrum</em> shows direct relationship with sect.<em>Aphanoneuron</em>, but indirect relationship with sect.<em>Leymus</em>.
