In this study, the karyotypes of mitotic chromosomes were determined of seven taxa of Salvia (Lamiaceae) collected from their natural habitats in Turkey: S. viridis (2n = 16), S. candidissima subsp. occidentalis (2n = 20), S. sclarea, S. ceratophylla, S. chionantha (2n = 22), S. viscosa and S. verticillata subsp. amasiaca (2n = 32). The karyotype formulae were 5m+3sm in S. viridis, 2M+5m+3sm in S. candidissima subsp. occidentalis, 1M+10m in S. sclarea, 8m+3sm in S. ceratophylla, 7m+4sm in S. chionantha, 9m+5sm+2st in S. viscosa, and 15m+1sm in S. verticillata subsp. amasiaca by the karyotype image analysis system. Somatic chromosome numbers ranged from 2n = 16 to 2n = 32. The ideograms were drawn based on centromeric index and arranged in decreasing size order. The present results were compared with the previous cytological studies in the genus.
