'Triomphe d'Amiens', 'La Brillante', 'Richard Smith', 'Mrs. Cleveland' are not synonyms in the modern sense of 'Général Jacqueminot', but distinct roses. They were deemed synonyms in the 1880s along with a number of others, as they were considered quite similar, and not worthy of separate listing and propagation.
Sam Kedem says this rose is almost thornless. Other people say it's definitely not thornless. These distinctions might be due to the "synonym" decision in the 1880s.
