Abstract: The fossil plants, described in this paper were obtained from the district Lin- Dian Xian of Hei-Long-Jiang Province, which are Cladophlebis sp., Onychiopsis sp., Protophyllum unduIahtm sp. nov., Viburniphyllum serrulatum sp. nov., and Platanophyllum sp. The sporopollen assemblage, represented by 19 genera and 20 species, is characterized by absolute predominance of ferns. Others are some gymnosperm and few angiosperms. The age of this flora is assigned to Aptian-Albian which is compared with that of the Patapsco formation of Potomac group of eastern America and that of the Lower Cretaceous of Kolyma Basin of eastern Siberia. During that time the climate of this region was wet and warm.
