Leaf epidermal microfeatures under Scanning Electronic Microscope (SEM), especially microfeatures of cuticle waxes, are considered to be a valuable character in plant taxonomy and systematics. Previously studies of leaf epidermal microfeatures mainly focused on levels of species or above species, whereas intraspecific study was rare. In order to explore intraspecific variation of leaf epidermal microfeatures, we selected multiple materials of Stipa purpurea and Oxytropis microphylla (29 and 15 samples, respectively) to observe the microfeatures of leaf cuticle waxes under SEM. The results revealed that these two species bearing high intraspecific variations of microfeatures of leaf cuticle waxes, and these variations lack of a strong correlation with any single biotic or abiotic factors, in contrast, it is affected by combined effects of multiple factors. Therefore, the use of microfeature of leaf cuticle waxes in taxonomical and systematic study will depend, to great extent, upon the detection of microfeature variation range, by extensive sampling along the whole distribution area.
