ABSTRACT: We observed five epidermis materials of Lespedeza Michx by scanning electron microscope (SEM), and compared three important indexes containing epidermal hair density, stomata type and stratum corneum among five materials. The results show that: epidermis hairs are abundant on both upper and lower epidermis of the two species of L. cuneata and L. davurica, only present on lower epidermis of other two species of L. cyrtobotrya and L. davidii. The shapes of five materials’ leaves epidermis hairs are juet same, there are large ecphymas with tumor appearance on all leaves epidermis hairs. The stomata of all materials besides L. cyrtobotrya sag into leaf epidermis cells, and all materials have developed stratum corneums on both sides. Drought tolerance of lespedeza closely relate to leaf epidermal hair density, sunken stomata and stratum corneum both are important reasons causing lespedeza has drought resistance ability.
