Abstract:Leaf abaxial epidermal features of five species of Chrysanthemum (C.indicum,C.lavandulifolium,C.nankingense,C.vestitum,and C.zawadskii) from Anhui Province were observed by light microscopy (LM),and the relationship between such features and the distribution and ecolope of the plants were studied.Results showed there were significant differences among the five wild plants in shape,size,and density of glandular hairs and non-glandular hairs;there were also disparities in size and density of stomatal apparatus,epidermal cell size and texture of horniness.Leaf abaxial epidermal features were related to distribution and eco-lope of the plants.In terms of these characteristics,we discussed genus classification of C.nankingense and compiled a taxonomic key of the five Chrysanthemum species from Anhui.
