All "polyanthus primroses" in the database are filed under "Primula elatior subsp. elatior". I believe this is in error, due to the record in some taxonomical resources that considers "P. polyantha" a synonym of P. elatior subsp. elatior. However, polyanthus primroses are hybrids of mixed origin, not a subspecies. They should appropriately be filed under "Primula × polyantha", as a separate entity from the (much more rarely encountered) botanical species.
