摘　　要：对云南水龙骨科隐子蕨亚科植物的区系地理进行了研究。云南水龙骨科隐子蕨亚科植物的地理成分已进行了划分,与邻近地区的区系联系也进行了比较,其区系起源也作了探讨。结果表明(1)云南是中国水龙骨科隐子蕨亚科植物的现代地理分布中心;(2)云南至喜马拉雅地区是水龙骨科隐子蕨亚科植物区系的分化中心;(3)云南水龙骨科隐子蕨亚科植物区系与四川、喜马拉雅地区和西藏的区系联系最密切;(4)水龙骨科隐子蕨亚科植物的起源中心可能在亚洲热带地区,但其分化中心则可能在云南西北部至喜马拉雅地区。最后列出云南水龙骨科隐子蕨亚科植物的系统名录。This paper dealt with the floristie geography of Polypodiaceae subfam. Crypsinoideae from Yunnan,China. The geographical elements of species were classified, the floristic relationship between Yunnan and those neighbouring regions was compared and the floristic origin of Polypodiaceae subfam. Crypsinoideae from Yunnan was studied. The floristic geographical characteristics are as follows：（1）Yunnan is the present geographical distribution center of Chinese Polypodiaceae subfam. Crypsinoideae; （2）Yunnan and the Himalayas are the differential center of Polypodiaceae subfam. Crypsinoideae; （3）The floristic relationship of Polypodiaceae subfam. Crypsinoideae in Yunnan is close to those of Sichuan, Himalayas and Tibet; （4）The original center of the subfam. , may be in tropical Asia, whereas its differential center is found in both Northwest Yunnan and the Himalayas. The systematic names of Polypodiaceae subfam. Crypsinoideae in Yunnan is also provided in this paper.
