The charophytes studied in this paper were obtained from the Xiagou Formation of Mayinghe section in Gaotai County of Gansu Province, including 7 species: Clypeator jiuquanen-sis (S. Wang) L. Grambast, Aclistochara huihuibaoensis S. Wang, A. cf. huihuibaoensis S. Wang, Mesochara stipitata (S. Wang) Z. Wang,Mesochara crassistipitata Zhang et Meng, Peckisphaera paragranulifera (S. Wang) Fu et Lu, Sphaerochara valida (Z. W. Li) comb. nov. , Sphaerochara sp. According to the stratigraphic range and distribution of charophytes,the present authors attribute the upper part of Xiagou Formation to early Cretaceous, probably Barremian.
