Well, from the name I would have thought it was named after a woman, but it was actually named for a Daylily Hybridizer and his name was Joyce Lewis. The flower to me looks the right shape, but I don't see much tan in with the yellow, of course that could just be the photo. Sorry, I am not much help, not very encouraging that there is not photo in the ATP data base. Just maybe someone here grows the plant and can be of more help.
