Abstract

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.
