Abstract:
In this paper, four species of the genus Cimicifuga L. from China(C. acerina,
C. simplex, C. yunnanensis, C. foetida var. foetida and C. foetida var. velutina )
were karyomorphologically investigated. All the taxa studied had the same chromosome num-
ber of 2n= 16 except for C. foetida var. foetida, in which a tetraploid cytotype was found
to occur in northwestern Yunnan. Their karyotypes are all presented. The chromosome
counts in C. yunnanensis and C. foetida var. velutina are reported here for the first time.
