In this study, it was aimed to determine the chromosome number of 21 Salvia L. species, to determine chromosome morphology, to reveal karyotype analysis in detail and to contribute to the cytotaxonomy of Salvia. In this context, the results are as follows: (i) the first report for the number of chromosomes of ten species, namely S. corrugata Vahl. (2n = 16), S. curviflora Benth. (2n = 16), S. darcyi J.Compton, S. greggii A.Gray, S. longifolia Nutt., S. vitifolia Benth. (2n = 22), S. subrotunda A.St.-Hil. ex Benth. (2n = 44), S. oppositiflora Ruiz & Pav. (2n = 56), S. stolonifera Benth. and S. atrocyanea Epling (2n = 60); (ii) the karyotypic variations and new chromosome numbers different from previous reports for three species, namely S. cardiophylla Benth. (2n = 36), S. cuspidata Ruiz & Pav. (2n = 44) and S. microphylla Sessé & Moc. (2n = 46); (iii) the same chromosome numbers from previous reports for eight species, namely S. campanulata Wall. ex Benth. (2n = 16), S. elegans Vahl. (2n = 20), S. involucrata Cav., S. mexicana Sessé & Moc. (2n = 22), S. apiana Jeps., S. leucophylla Greene, S. mellifera Greene (2n = 30), and S. splendens Ker Gawl. (2n = 44); (iv) the detailed chromosome measurements and karyotype analyses for all species studied for the first time; (v) the symmetrical karyotypes for all studied species; (vi) the variations resulting from dysploidy or polyploidy and discussing their reasons.
