Diversity and distribution of lycophytes and ferns in China

doi:10.17520/biods.2015256

Abstract

Abstract:

The species catalogue and phylogenetic arrangement are the basis of species diversity studies. We collated the latest lycophytes and ferns in China found in recent years using the system from Flora of China. There are 2,147 species, 5 subspecies, 118 varieties, 178 genera and 40 families of lycophytes and ferns in China, including 839 endemic species, which accounts for 39.08% of total species. The top five families are Dryopteridaceae (505 species, including subspecies and varieties), Athyriaceae (323 species), Polypodiaceae (280 species), Pteridaceae (266 species) and Thelypteridaceae (209 species). The top five genera are Polystichum (209 species), Dryopteris (176 species), Athyrium (137 species), Diplazium (98 species) and Pteris (97 species). The following five provinces are rich in lycophytes and ferns: Yunnan (1,365 species), Sichuan (875 species), Guizhou (838 species), Guangxi (785 species) and Taiwan (779 species). Endemic species are rich in families including Dryopteridaceae (257 species), Athyriaceae (169 species), and Pteridaceae (113 species) and genera of Polystichum (140 species), Athyrium (82 species), and Dryopteris (61 species).

Key words: plant taxonomy, conservation biogeography, biodiversity, conservation biology, pteridophytes
