%X It studied the phenotypic variation in the leaves of *Manglietia conifera* with 12 provenances seedlings from Vietnam, and measured the leaf morphological traits(length, width, area, perimeter, length-width ratio, petiole length) and micro morphological characteristics of stomata(density, length, width, area, length-width ratio) by the variance analysis, variable coefficient(CV), correlation analysis and principal components analysis(PCA). There were significant differences in leaf phenotypic traits among *M.conifera* provenances. The average CV of leaf morphological traits of provenance LC2 was the maximum(22.09%), and TQ2 was the minimum(12.76%), leaf area recorded the largest CV(28.60%) while stomata width recorded the smallest CV(5.19%). The result of correlation analysis showed that there was significant correlation between leaf phenotypic traits(*P*<0.05), leaf perimeter was significantly correlated with longitude, and leaf length-width ratio were significantly correlated with longitude and latitude(*P*<0.05), leaf phenotypic traits were not significantly correlated with longitude and altitude)(*P*<0.05). By PCA, the cumulative contribution rate of the first 3 principal components was 89.29%, basically represent all the information of the original character. By cluster analysis, the 12 provenances could be clustered into 4 groups at the Euclidean distance of 5. There is abundant variation of leaf phenotypic traits in *M.conifera* provenances, longitude and latitude have obvious influence on leaf morphological characteristics of *M.conifera*, and there is difference of variation degree among provenances and leaf phenotypic traits of *M.conifera*. Our study provides theoretical basis for genetic improvement of *M.conifera*.
