运用居群概念对翅果菊属的翅果菊Pterocypsela indica、多裂翅果菊P. laciniata、台湾翅果菊P. formosana等3种植物的主要鉴别性状进行形态测量和统计分析，评价其分类学意义。结果表明：叶片形状、叶片分裂程度、茎被毛多少、果喙长短等性状变异幅度大且存在种间交叉，不宜作为鉴别性状。根据研究结果，翅果菊、多裂翅果菊、台湾翅果菊三者之间并无明确的划分界限，建议将台湾翅果菊同多裂翅果菊一样归并到翅果菊中。

Based on the concept of population, morphometric and statistical analysis of the distinguishing morphological characters have been carried out on three species of Pterocypsela Shih, and its taxonomic significance has been evaluated. The results show that the character variation amplitude of the shape of leaf blade, the degree of blade split, stem with hairs or not, pod beak length is large and existences interspecific cross, so they can’t be used as identified characteristics. According to the results, we think that there are no prominent differences among P. indica, P. laciniata and P. formosana. It is recommended that P. formosana should be reduced as synonym P. indica like P. laciniata.
