Abstract: This paper deals with the Lower Carboniferous fossil plants, 19 genera and 41 species including 10 new species, such as Sublepidodeneron wcwgtanense, Lepidodendron sophoroides, Adiantites lianpingensis, A. matouensis, Archaeopteridium shaoguanense, Rhacopteris angusta, Rhodeites lanceolata, Neuropteris shaoguanensis, Potoniea turbinata and P. racemicarpa. According to the distributive regularity of those fossils in stratigraphic section of Early Carboniferous from Guangdong area, the authors propose to divide the flora into three assemblages from lower to upper, namely, 1, Sublepidodendron mirabile assemblage; 2. Cardiopteridium spetsbergense-Adiantites gothanii assemblage; 3. Archaeopteridium-Sphenopteris obtusiloba assemblage, which separately represent the dispositions of Dahu Formation (the 1st assemblage), the lower part of Ceshui Formation (the 2nd assemblage) and upper part of Ceshui Formation or middle part of Zhongxin Formation (the 3rd assemblage).
