Perhaps adding the well-accepted but incorrect name in the 'also sold as' section would suffice? That has certainly helped me find plants which have undergone name changes I was unaware of (or perhaps I've only known them as the well-accepted name), and I learn something as well even as I grumble (e.g., Autumn Joy sedum is really Herbstfreude - a name with too many consonants I have no clue how to pronounce!).
