摘要: 对我国特有属环根芹属的南竹叶环根芹(Cyclorhiza peucedanifolia(Franch.) Constance)进行细胞学研究,报道了其染色体数目为22,核型为2n=22=10m+12sm,核型为Stebbins的2A型。并根据伞形科已有的细胞学资料认为该种与环根芹(C. waltonii)作为同属植物是合适的,而且该属与美味芹族的凹乳芹属近缘。

关键词: 南竹叶环根芹, 核型, 分类

Abstract: Cyclorhiza peucedanifolia(Franch.) Constance (Apiaceae) endemic to China was karyo-morphologically studied.The result shows that its chromosome number is 22 and karyotype formula is 2n=22=10m+12sm. According to comparison this result with other cytological data of Apiaceae, it could be considered the classification of this species and C. waltonii in the same genus be reasonable and the genus Cyclorhiza be close to Vicatia DC in phylogeny.

Key words: Cyclorhiza peucedanifolia(Franch.), karyotype, classification
