But it is still listed as E. davisii on CoL which is what they follow here... Initially my search appeared to show me something else, but I had managed to click myself to a different website....
Thank you.

Of course, in the not too distant future, many (maybe most) of the database plant names here will have been superseded by new nomenclature and will seem quaint. In my seventy five years of growing cacti I have lived through so many classification/nomenclature schemes:
Britton & Rose, Berg, Backeberg, Hunt, Taylor & Zappi, et al.
If I had a dollar for every time I have changed names (or added synonyms) on plant labels I would have a lot of money by now. Of course, the big problem is we humans want to neatly classify and categorize plants according to our own concepts -- but nature will not play by our rules. It doesn't really matter that much to me -- I adapt to whatever nomenclature my individual correspondents currently use -- most of it will change eventually anyway.
What I really hope to avoid is for one of my posted photos to be captioned with a name that I did not intend to accompany it thus making the nomenclature at odds with that I use on my reference web pages.
I subscribe to the attribution nomenclature of "The Plant List" so I think it best my photos not be uploaded to the Forum database.
