      Thanks Marta. Berberis aquifolium/Mahonia aquifolium appear to refer to the same plant. I'm not sure which genus is current, though. I've IDed it as Mahonia aquifolium because that's what the Wikipedia name is, but we can always change the genus if needed.

      Mahonia aquifolium seems to be the currently accepted name here:
      https://www.gbif.org/species/3033865

      But, EOL seems to suggest Berberis aquifolium is more widely accepted:
      https://eol.org/pages/469325/names

      iNat, which we generally trust for taxonomic correctness favors Berberis aquifolium:

        Yes, I agree with you and Wikipedia also has it as Berberis :-) Posted 2 years ago, modified 2 years ago

    Just to add: The Catalogue of Life shows Mahonia aquifolium as an accepted name.
    https://www.catalogueoflife.org/data/taxon/3XJ3H
    Concerning Wikipedia I do not rely on it too much.
    BTW, I just checked - Wikipedia also has Mahonia aquifolia as accepted name and Berberis as synonym:
