摘要/Abstract

摘要： 依照王文采和李良千最新系统, 云南有铁线莲属( Clematis ) 植物59 种24 变种, 分属于3 亚属6组, 是中国该属种类分布最多的省份。横断山区可能是该属的起源、分化和特有中心, 而滇西、滇西南以及滇东南地区也与该属的分化有一定联系。云南铁线莲属植物特有现象较为突出: 含中国特有的56 种( 含变种), 占云南总种数的67.2% ; 云南特有16 种( 含变种), 占云南分布的中国特有种的35.0%。云南铁线莲属植物与国内邻近的四川关系最为密切, 西藏的关系最弱; 与国外邻近的缅甸具有一定的联系。

Abstract: According to the latest system of Wang and Li (2005), there are 59 species and 24 varieties in 6 sections of 3 subgenera in the genus of Clematis in Yunnan, which is the richest province in terms of species numbers in China. The Hengduan Mountains is regarded as centers of origin , differentiation and endemism of the genus. W, NW and NE parts of Yunnan may be closely related to or part of the center of differentiation. There are 56 species ( include varieties ) endemic to China , accounting for 67.2% of Yunnan′s total number of species. There are 16 species (include varieties) endemic to Yunnan, accounting for 35.0% of Chinese endemic number of species distributed in Yunnan. Among the adjacent provinces, Sichuan has the largest common number of Clematis to Yunnan, while Tibet has the smallest, implying their floristic relationships. The floristic links with Myanmar is also relatively weak.
