| 摘 要： | 本文研究了中国慈姑属植物间的系统发育关系。选取了12个与该属系统发育有较重要关系的特征,将8个已知分类群与外类群刺果泽泻属进行了比较。应用数量分支分析的Farris-Wagner方法,建立了中国慈姑属系统发育分支图。讨论了各分类群间的系统发育关系、该属起源和数量分支分析方法等问题。

| Abstract: | This paper explores the application of cladistic analysis for the phylogenetic relationships among eight taxa of Chinese Sagittaria. Twelve ecological and morphological characters which have important bearing, on the phylogenetic relationships of the genus have been compared with corres-ponding characters of the Echinodorus (as an out-group) in the character analysis. A cladogram of Chinese Sagittaria has been constructed by using Farris-Wanger's method of numerical cladistic analysis, On these grounds, some problems about the phylogenetic relationships among the taxa and the origin of the genus, as well as methods of cladistic analysis have been discussed briefly in the paper. |
