| Abstract: | The Late Devonian to Early Carboniferous flora from the Shashuigang Formation, Longjiang Formation and Ceshui Formation of Guangzhou area were described. There were 41 species of 23 genera. Among them, Filices and Pteridospermopsida were dominant (with 41.46% of the total number of species), and Lycopsida was also rich (with 36.59%), others were Sphenopsida (14.63%), Semina Gymnospermarum (4.88%) and Cordaitopsida (2.44%) successively. According to the distribution of fossil plants, there were three assemblages in this flora,they are: (1) Late Devonian fossil plants assemblage, (2) Early Early Carboniferous fossil plants assemblage, and (3) Late Early Carboniferous fossil plants assemblage. Based on the analysis of the above fossil composition, it indicates that this flora belonged to the Procathaysian flora. |
