The correct result should be Poa trivialis L. (the second one). The first result, Poa trivialis Leers, 1775 is flagged as doubtful. I feel like regardless, Poa trivialis L. should get some points for having an exact match in the authorship. I understand how that might cause issues with incomplete/erroneous taxon records on GBIF though, so I am not sure of the best way to fix this.
