摘要
刺儿菜复合体—大刺儿菜(Girsiumsetosum(Wild.)MB.)与小刺儿菜(G.segetumBge.)的分合问题在植物分类界一直存有争议。本文对不同产地、不同居群的全国200份刺儿菜复合体标本的若干性状选用E.Anderson的形象化散点图和柱状图方法进行研究分析,认为将大刺儿菜与小刺儿菜分为独立的种是合理的。
The paper introduces the morphological project on Cirsium setosum (Willd.) MB. and C. segetum Bge. It is analysed for the 200 C. setosum and C. segetum specimens from 20 provinces of China by means of pictorialized scatter diagram and histogram, and the result support the idea that C. setosum and C. segetum are both two independent species.
