Abstract:: Chromosome number and karyotype of Swida wilsoniana were analyzed by chromosome spreading.The results showed that the chromosome number of Swida wilsoniana was 2n=18.The karyotype formula was 2n=2x=18=4sm+14m.The ranges of chromosome length’s variation were between 1.02 and 1.81，and the index of kayotypic asymmetry was 58.06%.The results showed that the karyotypes of Swida wilsoniana belonged to ‘1B’ type.
