Salvia ramamoorthyana and s. Omissa (lamiaceae), two names for two old and largely confused species from mexico

The original material of Salvia ramamoorthyana (S. sect. Sigmoideae) is mixed and belongs to two different species. The type corresponds to a taxon generally known as S. nepetoides. Instead, the analysis of the holotype of S. nepetoides (P!) showed that this does not correspond with the taxon traditionally identified as such but belongs to S. amarissima, a species of S. sect. Uricae. Hence, S. ramamoorthyana is re-circumscribed to the plants usually named S. nepetoides (S. sect. Sigmoideae), the true S. nepetoides is regarded as synonym of S. amarissima (S. sect. Uricae) and the new species S. omissa is described to designate the taxon under the name S. ramamoorthyana not including its type. Descriptions and distribution maps of S. omissa and S. ramamoorthyana and an updated identification key to the species in the section are also provided.
