Cuticular characteristics of two species of Cheirolepidiaceae conifer collected from the Cretaceous Guantou Formation, in Jingling of Xinchang County, Zhejiang Province, Pseudofrenelopsis papillosa Chow and Tsao and Pseudofrenelopsis parceramosa Watson, are studied with SEM and LM. They had been extinct by the Tertiary. Of them, morphological and epidermal characteristics of the former species P.papillosa are completely consistent with those of the holotype ( Chow and Tsao，1977). However, pseudofrenelopsis parceramosa is characterized by smooth internode cuticle and regular stomatal arrangement. Besides, papillae are not found in the subsidiary cells, and size of stomatal apparatus and free leaf and internode length etc. are not the distinctly same as those of other species of the genus Pseudofrenelopsi. CO2 concentration in the late epoch of the Early Cretaceous is estimated by stomatal ratio of P.parceramosa (NLRs), which is from 861 to 1047ml/L. It is suggested that the climate in the Xinchang Basin, Zhejiang Province, was warm or hot and arid or semiarid.
