Somatic chromosomes of three Parnassia species collected in Xinjiang, China were observed. They had commonly the simple chromocenter type of resting chromosomes and the proximal type of mitotic prophase chromosomes. The chromosome numbers of 2n=36 and 2n=36+1~8 supernumerary chromosomes for P. bifolia were reported here for the first time. The chromosome number of 2n=18 for P. laxmannii and P. palustris var. palustris was verified the previous reports. Three Parnassia species had similar small size chromosomes and the basic chromosome number of x=9. The karyotype of Parnassia laxmannii consisted of 18 mediancentromeric chromosomes, while that of the other two species consisted commonly of median- and submedian-centromeric chromosomes.
