摘要	Salvia is a genus with surprisingly diverse chromosome numbers. In this paper six species were cytologically studied from Hengduanshan Mountains region, where is one of two diversification centers of the genus. S. przewalskii var. przewalskii is a tetraploid with the chromosome number of 2n=4x=32, other five species are the diploids with chromosome numbers of 2n=2x=16. The basic chromosome number x=8 was inferred for an species studied, which was different from x=7, 11 and 16 reported for species of the genus distributed in other regions. Several recent cytological studies on different groups from Hengduanshan Mountains region showed that only few polyploids infers that variation of karyotype structure at the diploid level seems to play a leading role and sympatric speciation via hybridization and polyploidization has played a minor role in speciation of some groups in Hengduanshan Mountains region.
