Abstract：[Objective]To further explore and understand the biodiversity and geographical distribution patterns of lycophyte and fern flora in the Jiaozi Mountain National Nature Reserve of Yunnan,and to furnish data support for the conservation and utilization of these plants within the reserve.[Method]Drawing on data from scientific expeditions,routine monitoring efforts,and literature reviews conducted in the Jiaozi Mountain National Nature Reserve in Yunnan,this study analyzed the species diversity of fern flora in the reserve,focusing on species composition and geographical distribution.[Result]The results indicate that the Jiaozi Mountain National Nature Reserve harbors 120 lycophytes and ferns,which belong to 15 families and 31 genera,accounting for 36.59%of the total lycophyte and fern families in China.Among these,five families—Athyriaceae,Cystopteridaceae,Dryopteridaceae,Pteridaceae,and Polypodiaceae—each contain more than five species.At the genus level,Polystichum,Dryopteris,and Adiantum exhibit the highest species diversity,while monotypic genera account for 13(41.94%of the total genera).Additionally,one provincially protected species,Neocheiropteris palmatopedata was recorded.In flora,cosmopolitan families dominate at the family level(12 families);cosmopolitan genera prevail at the genus level(12 genera);and East Asian elements prevail at the species level(62 species).
