摘要:

本文以可收集到的标本,运用形象化散点图、柱状图等方法,对国产山梗菜亚属Subgen.Tupa E.Wimm.性状的变异幅度及相关性进行了统计分析,并结合花粉特征及种皮表面纹饰,对该亚属的国产种进行了修订,发现一新种(叶苞山梗菜L.foliiformis)一新亚种(贵州山梗菜L .colorata subsp.guizhouensis),同意廉永善对L .hybrida的处理,并把L .taliensis也归人L .colorata,将后者分为三个亚种。对于L .kwangsiensis我们的分析结果支持廉永善在《中国植物志》中的划分,给予降级,并置于L .davidii内。

Abstract:

Based on specimens as many as available, a quantitative analysis of character varia-
bility and correlation in Lobelia Subgen. Tupa was carried out with the results shown by
pictorialized scatter diagram and histogram. Pollen grains and seed coat were examined un-
der SEM. The classitication of the subgenus in China is revised. Twelve specipes are recog-
nized; a new species, L. foliiformis, and a new subspecies, L. colorata subsp. guizhouensis,
are described; L. taliensis is reduced to a subspecies or L. colorata, which consists of three
subspecies; L. kwangsiensis is treated as a variety of L. davidii in accordance with the treat-
ment made by Lian Yong-shan in Fl. Reip. Pop. Sin.73 (2)
