摘要	Karyology of six Silene (Caryophyllaceae) species from the Hengduan Mountains of SW China was analyzed for the first time. The results indicate that the basic chromosome number for the six species is x=12, with karyotypic formula as follows: S. orientalimongolica (2n=2x=24=24m); S. nepalensis (2n=2x=24=16m+8sm); S. trachyphylla (2n=2x=24=8m+6sm+10st); S. davidii (2n=4x=48=48m); S. nigrescens (2n=4x=48=40m+8sm); S. yetii (2n=6x=72=64m+8sm). The karyotype asymmetry of S. orientalimongolica and S. davidii are 1A and S. trachyphylla is 3A, distinct from the other three species with 2A type. The significance of the cytological evolution of Silene from the Hengduan Mountains is briefly discussed.
