GBIF Backbone Provisional Names
A checklist of provisional names not found in any of our sources used to assemble the backbone taxonomy, but which can be found in primary species occurrence records. Names in this checklist should be removed once they appear in other trusted checklists. When adding new names into this list all entries should be assigned some remarks why this name exists and ideally a link to some other online resource.
