to be deposited on the pollinator. When the pollinator withdraws from the flower, the lever returns the stamens to their original position. In older, female stage flowers, the stigma is bent down in a general location that corresponds to where the pollen was deposited on the pollinator's body. The lever of most ''Salvia'' species is not specialized for a single pollinator, but is generic and selected to be easily released by many bird and bee pollinators of varying shapes and sizes. The lever arm can be specialized to be different lengths so that the pollen is deposited on different parts of the pollinator's body.Classen-Bockhoff R, Tweraser E, Wester P. 2003. The staminal lever mechanism in Salvia L. (Lamiaceae) – a review. Plant Biology 5: 33–41. For example, if a bee went to one flower and pollen was deposited on the far back of her body, but then it flew to another flower where the stigma was more forward (anterior), pollination could not take place. This can result in reproductive isolation from the parental population and new speciation can occur. It is believed that the lever mechanism is a key factor in the speciation, adaptive radiation, and diversity of this large genus.

(''Labiatarum Genera et Species'' (1836)) is still the only comprehensive and global organization of the family. While he was clear about the integrity of the overall family, he was less confident about his organization of ''Salvia'', the largest genus in Labiatae (also called Lamiaceae). Based on his own philosophy of classification, he wrote that he "ought to have formed five or six genera" out of ''Salvia''. In the end, he felt that the advantage in placing a relatively uniform grouping in one genus was "more than counterbalanced by the necessity of changing more than two hundred names." At that time there were only 291 known ''Salvia'' species.

Subdivision

Bentham eventually organized ''Salvia'' into twelve sections (originally fourteen), based on differences in corolla, calyx, and stamens. These were placed into four subgenera that were generally divided into

Other botanists have since offered modified versions of Bentham's classification system, while botanists in the last hundred years generally do not endorse Bentham's system. It was long assumed that ''Salvias unusual pollination and stamen structure had evolved only once, and that therefore ''Salvia'' was

. Walker and Sytsma (2007) clarified this parallel evolution in a later paper combining molecular and morphological data to prove three independent lineages of the ''Salvia'' lever mechanism, each corresponding to a clade within the genus. It is surprising to see how similar the staminal lever mechanism structures are between the three lineages, so ''Salvia'' proves to be an interesting but excellent example of convergent evolution. Walker and Sytsma (2007) also addressed the question of whether ''Salvia'' is truly

. The information attained by Walker and Sytsma (2007) supporting the three independent origins of the staminal lever indicate that ''Salvia'' is not the case where 15 species (currently not members of the genus) are actually members of ''Salvia'' but underwent character reversals—in other words, ''Salvia'' is paraphyletic as previously circumscribed. In 2017 Drew et al. recircumscribed ''Salvia'', proposing that the five small embedded genera (''Dorystaechas'', ''Meriandra'', ''Perovskia'', ''Rosmarinus'', and ''Zhumeria'') be subsumed into a broadly defined ''Salvia''. This approach would require only 15 name changes whereas maintaining the five small genera and renaming various ''Salvia'' taxa would require over 700 name changes. The

of individual species within ''Salvia'' has undergone constant revision. Many species are similar to each other, and many species have varieties that have been given different specific names. There have been as many as 2,000 named species and subspecies. Over time, the number has been reduced to less than a thousand. A modern and comprehensive study of ''Salvia'' species was done by Gabriel Alziar, in his ''Catalogue Synonymique des ''Salvia'' du Monde'' (1989) (''World Catalog of ''Salvia'' Synonyms''). He found that the number of distinct species and subspecies could be reduced to less than 700.
