摘要
对云南水龙骨科星蕨亚科植物种类的地理成分进行了划分,并对云南与邻近地区的区系联系进行了比较,对云南该亚科植物的区系起源也作了探讨。得出如下结论云南是中国水龙骨科星蕨亚科植物的现代地理分布中心;该亚科植物是典型的热带亚洲的区系成分;与广西和越南北部的区系联系最密切;云南东南部和越南北部是水龙骨科星蕨亚科植物的多样性中心。
This paper deals with the floristic geography characteristics of Polypodiaceae subfam. Microsoroideae in Yunnan Province of China. The geographical elements of species in this subfamily have been classified,the floristic relationship between Yunnan and those neighbouring regions has been compared and the floristic origin of Polypodiaceae subfam. Microsoroideae in Yunnan has been studied in this paper. The conclusions are as follows：Yunnan is the present geographical distribution center of Chinese Polypodiaceae subfam. The floristic elements of Microsoroideae are typical Tropic Asia and closely related to the flora of Guangxi and northern Vietnam. The area from southeastern Yunnan to Northern Vietnam is the diversity center of Polypodiaceae subram. Microsoroideae.
