I just don't know, hence the confusion. Calylophus is not a common name, it is a genus name. The botanical people are always changing everything around, but usually if I google, I find some reference somewhere to the new genus name. Instead I saw a lot of references to a pink mexcian evening primrose with the name given as Oenothera berlandieri. Maybe they changed that to something else and then changed Calylophus genus to Oenothera. That's what I wanted to get straight. And seems like it would be useful, after the botanical authorities change a genus or species name, to list it in the plant database with the new name, then include the old name also. Because hardly anybody would be searching for info on a plant with a brand new botanical name not yet generally available to people.
