首次系统调查了猫儿山自然保护区的叶附生苔类植物区系.通过野外考察和文献考证,发现猫儿山现有叶附生苔类植物3科8属19种,其中16种为猫儿山首次发现,15种属于典型的叶附生苔类植物.细角管叶苔(Colura tenuicornis)和叶生角鳞苔(Drepanolejeunea foliicola)为广西苔类植物新记录.叶附生的管叶苔属(Colura)为广西新记录属.猫儿山的叶附生苔类植物区系的主要成分为东亚成分(占36.84%),这反映了猫儿山的叶附生苔类植物区系具有显著的东亚特点.异胞扁萼苔为Radula gedenaGottsche ex Steph.的新拟名.

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.
