【Abstract】 Pollen grains of 25 Chenopodiaceae species from Xinjiang were observed under the light microscope and SEM. To suit the needs in distinction of the similar pollen morphology of various Chenopodiaceae plants in present sporo—pollen analysis study, 4 pollen morphological generitypes were distinguished based on the features on size and aperture of the pollen.
