Salvia rosmarinus is now considered one of many hundreds of species in the genus Salvia.
Formerly it was placed in a much smaller genus, Rosmarinus, which contained only two to four species including R. officinalis, which is now considered a synonym of S. rosmarinus.
The other species most often recognized is the closely related, Salvia jordanii (formerly Rosmarinus eriocalyx), of the Maghreb of Africa and Iberia.
The name of ros marinus is the plant’s ancient name in classical Latin.
Elizabeth Kent noted in her Flora Domestica (1823), “The botanical name of this plant is compounded of two Latin words, signifying Sea-dew; and indeed Rosemary thrives best by the sea.”
Both the original and current genus names of the species were applied by the 18th-century naturalist and founding taxonomist Carl Linnaeus.
