摘要： 通过野外调查和文献查阅方法对安徽省细鳞苔科植物多样性进行了研究.结果表明，安徽省细鳞苔科植物共有11属46种，包括1个新纪录属（Myriocoleopsis Schiffn）和10个新纪录种.细鳞苔属（12种）和疣鳞苔属（10种）是优势属.区系成分组成中，热带成分最高，共27种，占总数的58.7%；东亚成分次之，共13种，占总数的28.26%.海拔400 m以下的湿润低山沟谷和海拔1 600m以上的高山台地细鳞苔科植物最多.还首次在石台县牯牛降自然保护区发现4种叶附生苔类，将叶附生苔在华东地区的分布北界推移到30°N以北，并对该地区叶附生苔生存状况进行了分析.

Abstract: This paper studies the diversity of Lejeuneaceae species in Anhui Province based on field data collections and literature review. Our study reveals the occurrence of 46 species in 11 genera of Lejeuneaceae in Anhui Province, including one newly recorded genus (Myriocoleopsis Schiffn.) and 10 newly recorded species. The genus with the largest number of species is Lejeunea (12 spp.) and the second largest genus is Cololejeunea (10 spp.). Floristic analysis shows that tropical elements are the most prevalent among Anhui Lejeuneaceae flora with 27 species, accounting for approximately 58.7% of the Lejeuneaceae species in Anhui Province. East Asian elements, the second most prevalent group, with 13 species accounts for approximately 28.3% of the total number of species. The optimal habitat conditions for most Lejeuneaceae are low mountainous and ravine areas below 400 m as well as alpine areas above 1 600 m. Four epiphyllous liverwort species are newly reported from Guniujiang Nature Reserve in Shitai County. The distribution of epiphyllous liverworts in Eastern China therefore extends north of latitude 30°N. We also analyzed the status of epiphyllous liverworts in this area.
