Tropicals & Tender Perennials: It's an "Easter Cactus"......well not really, but, 1 by RUK

Thank you so much Clare and Hillary!
I did see your name last night at the Epiforums online list, Clare. Good to see you there too!!
Lots of good information here in both your excellent posts.
So, some changes can be expected due to temps, light conditions and such. And if you can't read a/the label you are in trouble too.
Now seeing the contest "match the picture with the hybridizer" on Epiforums, I am absolutely amazed that there are people able to that. (The answers are dropping in at the forum.) I am looking at it and I scratch my head, how is that possible from those little snippets of a flower.
I would think one has to be absolutely familiar with the work of a particular hybridizer. Impressive.

One of the reasons I am asking these questions is the following:
I bought in 1999 4 small plants from Kakteen Haage/Germany. This is one of the excellent nurseries there and well known for their Epicactus hybrids.
Here is the list of the stuff I had bought, with description:
Golden Fleece - bent yellow petals with a dark stripe and long skinny sepals. (translated)
Edna Stoddard - white
Yellow Gem - bell shaped flower, strong yellow
Gitti Paetz - lilac petals and bronze sepals
I still have all original tags, so there is no mistake as to what I bought.
So when the first one flowered - lilac is the main petal color on Gitti Paetz, but the sepals are quite red and I could imagine perhaps a bronzed red. But it is the only one of the 4 with "lilac" ( lila) in the description. Haage shows the same flower at their website. Ok, it is a match. Except, googling the flower and comparing with another German website, Roger Paetz is a precise match in looks to my flower, while Gitti Paetz indeed has true bronze sepals. Who is correct?
I would assume the place I bought it from. Therefore I call it Gitti Paetz unless told otherwise.

That leaves the next 3: Edna Stoddard
I just took some pictures in the morning breeze -
White? Yes, but it has yellow sepals and touches of yellow on the petals. The flower is not totally open yet, bell shaped ? Hmmm (old flower to the left is closing.)
Again look at the Yellow Gem and Golden Fleece descriptions, they don't fit. Edna Stoddard is only the best fit. I asked Uli Haage last Summer the same question, he confirmed it as the best fit with the info on the others given.
Hence my questions! I do not find this easy!!

The 3. plant is growing very slowly, it produced buds this year, they aborted.
The 4. plant expired last year. The original piece never took off.
So even good labels don't really give me absolute confidence here. In this particular case I can only report the ids as to the best I know. In the meanwhile we are enjoying some truly spectacular flowers here.
