Thanks Sue. I knew it wasn't a cactus because of the flowers. I might
have figured this out on my own if I had worked on it. Of course, I
wanted an excuse to post my pictures here anyway.

Quite right. That is what the group's for!

It crossed my mind that the flowers resembled pictures I had seen
labeled as carrion flowers. If I had searched "carrion flowers" on
Wikipedia, I would have recognized Stapelia as the one I was thinking
of. I would have gotten at least that far. I actually didn't realize
that Stapelias were plants that (in some cases) resemble cactus.
Thanks for the link, they certainly come in a nearly endless number of
varieties. By the way, I have never noticed any smell at all from the
flowers on my plant. When I get a chance, I'll get my nose in close and
see if there is a faint smell that I have been missing. Steve

It's never very strong but in a greenhouse or small room a flowering
Stapelia gives the impression somebody's farted. So I grow it on the
lavatory windowsill where it won't matter! It doesn't attract British
flies much and I don't think it's ever set seeds.
