      Description

      Not sure how common this is, but here's an example where two plant names that are objective synonyms are both treated as "Accepted species" in the GBIF portal: Poissonia heterantha http://www.gbif.org/species/5629609 and Coursetia heterantha http://www.gbif.org/species/2959395, These two names are objective synonyms, and we have this information already available in the IPNI data dump. Both Poissonia heterantha and Coursetia heterantha have the same "http://rs.tdwg.org/dwc/terms/BasionymID" value, namely "urn:lsid:ipni.org:names:520610-1" (I guess BasionymID is deprecated now).

      So, in theory, it should be possible to catch these cases by checking for each value of BasionymID whether there is more than one "Accepted species". This logically can't be the case.

      There's also a bigger issue here, namely IPNI doesn't make any assertions about whether a name is "accepted" or not, so if and when IPNI is updated in GBIF there ar likely to be a bunch of names for which GBIF doesn't know which one is "accepted". For example, the latest (June 2015) edition of CoL has no information at all on Poissonia heterantha, despite the combination being published in 2003 http://www.jstor.org/stable/3094008. The Plant List, does have this name, and treats it as the accepted name for this taxon http://www.theplantlist.org/tpl1.1/record/tro-50233766.

          The current backbone build algorithm only allows a single name from a group of names sharing the same basionym to be accepted. The backbone now treats Poissonia heterantha as an objective synonym
