The genus Baccharoides http://www.gbif.org/species/3087252 occurs in Africa and Asian, but the GBIF maps shows occurrences in North and South America. Some of this looks like cultivated specimens (e.g., http://www.gbif.org/occurrence/415928562/verbatim and http://www.gbif.org/occurrence/1090550838/verbatim ) but most are due to incorrect synonymy resulting from ignoring the authorship of a name that has a homonym (sigh).
Looking at the results for http://www.gbif.org/occurrence/search?HAS_GEOSPATIAL_ISSUE=false&GEOMETRY=-140.89%20-50.69%2C-140.89%2015.18%2C-30.67%2015.18%2C-30.67%20-50.69%2C-140.89%20-50.69&TAXON_KEY=3087252 there are occurrences for "Vernonia macrocephala A.Rich." which are treated as a synonym of "Baccharoides adoensis". The verbatim records gives the name as "Vernonia macrocephala Less." (not "A. Rich.").
"Vernonia macrocephala Less." is the basionym of "Lessingianthus macrocephalus (Less.)" H.Rob.http://www.ipni.org/ipni/idPlantNameSearch.do?id=961988-1 and so the occurrence is actually of a member of the genus South American genus Lessingianthus. The name "Vernonia macrocephala A.Rich." http://www.ipni.org/ipni/idPlantNameSearch.do?id=258770-1 is, I gather, a homonym of "Vernonia macrocephala Less." and is regarded as a synonym of "Baccharoides adoensis" (an African species).
In summary, it looks like the author name has been ignored when interpreting "Vernonia macrocephala Less." and hence it's been mapped to the African "Vernonia macrocephala A.Rich." when it should have been mapped to the South American "Vernonia macrocephala Less."
