Abstract: The epiphyllous liverworts of the Maoershan Nature Reserve of Guangxi Province were reported for the first time through field surveying and data refereeing.There are 19 species of epiphyllous liverworts belonging to eight genera of three families in Maoershan Nature Reserve, including 16 species new to the area investigated, and 15 species belonging to the typical epiphyllous liverworts.Colura tenuicornis and Drepanolejeunea foliicola are new to the liverwort flora of Guangxi.The epiphyllous Colura is newly reported for Guangxi.The number of East Asian species accounts for 36.84% of the total number of the epiphyllous liverworts in Maoershan Nature Reserve.Such a result reveals that the epiphyllous flora of Maoershan is closely related to the East Asian flora of the epiphyllous liverworts.
