For reason's that I can't fathom, GIF has Lessingianthus rosmarinifolius (Less.) H.Rob. and Santolina rosmarinifolia L. as synonyms. This results in a strange map for the South American species Lessingianthus rosmarinifolius http://www.gbif.org/species/3117819 which puts most of this species' records in Spain:
Lessingianthus rosmarinifolius has as it's basionym Vernonia rosmarinifolia Less. http://www.ipni.org/ipni/idPlantNameSearch.do?id=264470-2 whereas Santolina rosmarinifolia L. is the original name.
I can't work out from GBIF which checklist source states that these two names are synonyms.
