After brief introduction of the phylogenetic relationships of pteridophytes,we summarized the traditional classification system and system based on modern molecular systematics,current situation and new progress as well as future study expectation of floristic geography of the pteridophytes in China in the paper.The results of molecular phylogeny showed that the pteridophyta and some groups are not natural groups.The diversity of the floras and distribution in ferns in southeast China is abundant,while northwest is less.The diversity of the south and southwest China is extraordinarily rich,and the distribution center of many temperate genera is the southwest China.The main issues of flora of pteridophytes in China were analyzed here,and the effect of ferns in ecosystem,the study of special habitat,the application of numerical analysis in ferns’ floras study,and the intersect between floristic geography and other related subjects could be hot topics and areas needed to reinforce in the future.
