By examination of Calligonum pumilum A. Los. and Calligonum ruoqiangense Liou f.,collected from natural habitats,and the analysis of their variance,this paper revealed that the morphological characters of these specimens are quite different from each other,especially in the twist direction of ribs on fruits,rows of bristles along each rib,rigidity,interweaving degree of bristles,and their geographical distribution. Therefore,it is suggested that C. pumilum and C. ruoqiangense should be considered as two independent species. By examination of Calligonum pumilum A. Los.
