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
