Abstract: The main purpose of this study is to analyze palynomorphological characters among the member of this genus and evaluating the efficiency of these features in systematics of the genus. Pollen of 14 species belonging to genus Chenopodium was studied by Scanning Electron Microscope (SEM). All studied species have pollens with, spheroidal shape, radial symmetrical, isopolar and peripolporate. The exine surface ornamentation is scabrate. All studied species haven indicating that there are two pore types on pollen surface: foveat and perforate. The results of this studies show that pollen micromorphology can be considered used to superstation between species this genus.
