摘　　要：百花山蕨类植物区系共有15科、26属、60种(含变种),在北京植物区系中占重要地位。其中1属、5种、1变种为《北京植物志》增补种类,1变种(百花山瓦韦)为新分类群。百花山蕨类植物的分类群结构与北京市基本一致,具有明显的温带分布区的特点,与热带分布有密切的联系。笔者对百花山新记录的蕨类植物作了编目,并编制了分科、属、种的检索表。Pteridophyte in Baihuashan Mountain, which accounts for important status in Beijing flora ,includes 15 families, 26 genera and 60 species （including variants）,of which 1 genera, 5 species, 1 variant are supplement of ＂Beijing Flora＂. 1 variant is a new taxa,it is Lepisorus hsiawutaiensis var. cryptonerus. Pteridophyte taxa structure in Baihuashan Mountain is basically consistent with in Beijing,of obvious temperate zone characteristics, which is closely related with tropical distribution. Pteridophyte in Baihuashan Mountain are cataloged of new record in Beijing and the key characters of families, genera and species.
