AbstractKaryotypes of 16 species and two varieties of Chinese Salvia were determined in this study. Of the 18 Salvia taxa, chromosome numbers of eight taxa and karyotypic analyses of 13 taxa were reported for the first time. The basic chromosome number of all taxa in this study was x = 8. With the exception of tetraploids S. campanulata var. codonantha and S. przewalskii, the taxa were diploid. One B chromosome was found in part of the mitosis metaphase cells of S. aerea. The present results were compared with previous cytological studies. The population of S. castanea having x = 11 from India may be misidentified. Consequently, all Salvia taxa from China may have the same basic chromosome number of x = 8. The population of S. przewalskii reported as tetraploid from Russia and populations of S. evansiana reported as tetraploid from Yunnan and Sichuan of China were very likely to be misidentified. Therefore, S. przewalskii may be tetraploid without diploid representatives, and S. evansiana diploid without any tetraploids. Salvia campanulata is both diploid and tetraploid. The B chromosome is rather unsteady among populations of the same species, even within the same tissues.
