Abstract:

Aims: Species checklist is the background data of the biodiversity of a region. A timely update of the list plays an important role in the protection of biodiversity and the promotion of basic data sharing. In order to summarize the research results of the taxonomy of bryophytes in Anhui Province in time, it is necessary to revise the list of bryophytes in the province.

Method: Based on the collection and analysis of the published records, we updated the checklist of bryophytes in Anhui Province.

Results: In total, the present checklist includes 777 species belonging to 253 genera in 95 families, with three hornwort species in three genera and three families, 185 liverwort species in 62 genera and 36 families, and 589 moss species in 188 genera and 56 families. Families with more than 25 species are Brachytheciaceae, Lejeuneaceae, Pottiaceae, Bryaceae, Hypnaceae, Mniaceae, Leucobryaceae, Entodontaceae and Meteoriaceae. Genera with more than 15 species are Brachythecium, Bryum, Entodon, Porella, Plagiochila, Hypnum, Fissidens, Plagiotheciumand Frullania. East Asian geographical element (44.40%) is the largest component of the bryophyte flora of Anhui Province, while temperate element is 31.53% (of which the northern temperate element is the most, accounting for 25.61%), and tropical element is 18.92% (of which the tropical Asia element is 10.30%). There are 55 species of China's endemic species, one endangered species, and eight vulnerable species in Anhui Province. The survey of bryophytes in Anhui Province shows regional imbalances.

Conclusions: Our results suggests that, while extensive surveys are carried out, the revision of the checklist and specialized studies should be strengthened in Anhui Province. Furthemore, comparative studies of species diversity under temporal and spatial changes should be carried out in areas where conditions permit.
