Abstract: A numerical taxonomy study of 24 populations of three dodders was studied by choosing 33 mor-phological characters and using the UPGMA. The result is shown as follows: (1) Cuscuta japonica Choisy is close to C. reflexa Roxb., while C. chinensis Lam. is alienated from them. (2) There are rich genetic both in C. japonica Choisy and in C. reflexa Roxb.. It is suggested that C. japonica Choisy could be di-vided into two varieties, and C. reflexa Roxb. into three varieties.
