摘要:

文章简明介绍了现代分支系统学的分支格局原理和组份分析方法,并应用于李朝銮(1990,表2)的中国白粉藤属14种植物数据的分支分析。得出13个可能的最简约的二歧分支图,图长41步。这些分支图与李(1990)图2:13的比较表明,中值淘汰法不如组份分析方法有效,而且中值淘汰法有表相学和(或)进化系统学的疑问。

关键词: 分支格局, 组份分析, 分支图, 中值淘汰法

Abstract:

The principle of cladistic patterns and the method of component analysis (MCA) are introduced concisely with a hypothetic example and then applied to the cladistic analysis of the data on Chinese plants of the genus Cissus L. from Li (1990, Tab. 2). Thirteen resulted possible dichotomous cladograms are illustrated with characters, and they are the most parsimonious ones, all with a length of 41 steps. Comparison between them and the one by
Li (1990, Fig. 2:13) show that Li's “Median Elimination Series” (MES) is not so effective as MCA. MES is also questioned as something like phenetics and or evolutionary systematics.

Key words: Cladistic patterns, Component analysis, Cladograms, Median Elimination Series
