The reference to Salvia officinalis by Liberato ao probably refers to another species. This applies also to the reference by Holcomb (2000a) of lamii on Salvia splendens and S. coccinea. And also the association of lamii with Salvia officinalis and Rosmarinus officinalis (Humphreys-Jones ea) derives from a overly wide concept of that species.
