Abstract: In the present paper, previous taxonomic systems of Taxodiaceae were reviewed. According to the results of cladistic analysis and phenetic analysis. a new taxonomic system was proposed. Based on external morphological features and evidences from other aspects, the taxonomy of Taxodiaceae was revised. 9genera 12 species and 3 varieties were recognized in the family Taxodiaceae.Cunninghamia lanceolata var. corticosa. Cunninghamia unicanaliculata var. unicanaliculata and var. pyramidalis were treated as synonyms of Cunninghamia lanceolata. The author supports the viewpoints that Cryptomeria fortunei and Cunninghamia konishii should be reduced to varietal rank respectively and Taiwania flousiana should be treated as a synonym of Taiwania cryptomerioides.
