Description
''
Salvia rosmarinus'' (rosemary), widespread in the Mediterranean region, and ''
Salvia jordanii'' (formerly ''Rosmarinus eriocalyx''), native to northwest Africa and southern Spain have long been widely recognized. ''

Rosmarinus palaui'' was first described as a species in 2002, although recognition of this species remains controversial. Recent research has indicated that while ''S. granatensis'' forms a
