Please take note of my earlier post.
To give radiiflorus as a subsp. of poeticus would give rise to problems with it's own subspecies.
As stated earlier, to list a subspecies where the authority on Narcissus, the RHS which has upated information on current research, has given this species outright status cannot work. It can work as a synonym, which means that at some time in history it has been given that name.
Note the dates, earlier names always take precedence over later names. This happened often, where another person named a plant which had previously been named. There's much shaking up now over taxonomic names both in the plant world and animal kingdom, many names are being reverted to the original one and this if often being achieved through DNA testing.
