| 摘 要： | 以晋祠段为代表的中国斯蒂芬期植物群与欧美同期植物群有许多相同分子，但其中地方性植物分子比重较大，应属早期华夏植物群的一部分．该植物群与以太原组中上部为代表的Ｎｅｕｒｏｐｔｅｒｉｓｐｓｅｕｄｏｖａｔａ－Ｌｅｐｉｄｏｄｅｎｄｒｏｎｐｏｓｔｈｕｍｉｉ组合也存在一定差别，表现在典型的华夏植物群的重要成员尚未出现．

| Abstract: | Though the Stephanian Flora of China, represented by the Jinci Member that is the Lower part of the Taiyuan Formation(Triticites Zone), includes some common members with that of Euramerica, it also contains a number of endemic forms, which mostly are the representatives of the Noeggerathiopsida and some elements of the orient-type Lepidophytes. It is clear that the Cathaysian flora had appeared in the world by the Stephanian stage. The difference between the Taiyuan Formation Flora(Lepidodendron posthumii-Neuropteris pseudrmata Assemblage) and the Jinci Member Flora is that some key forms of the MiddleUpper Taiyuan Formation such as Einplectopteris triangularis, Emplectopteridium alatum, Lobatannularia sinensl's, AlethOPteris ascendens and A. norinii were not occurred in the Jinci Member. |
