Hi Musiche...It looks like Stapelia commonly known as carrion or Toad Plant.
Could be S. gigantea, also known as S. nobilis and S. marlothii.

Toni

Toni, no, that's something else. The blooms on the ones you name are about 8" across and are yellow. This has to be one of those oddities that blooms once every 25 years or longer. It looks like a type of carrion flower, so I'll bet he's holding his breath...

Rafflesia arnoldii?

Yes, it's Rafflesia.

Hi
I can't get the pic!! Someone is actually culturing Rafflesia?? gary

Try this, to get to the OP's link, Gary.

Here is a link that might be useful: pic

Hi
Obviously NOt culturing just visiting lol Have heard they have advanvanced to an eighty percent chance of innoculation using tetrastigma "Vietnamese yam"as a host .
have heard that Kew gdns and Missouri Bo is attempting it . Heard Fairchild was also but can't find in the catallog. They seem to be guarding the transmission method ;probably because they bring so many tourists?? lol
The giant Amorphos are getting commonplace in the larger gardens and one of these would be a draw? Fantasti plant for sure!! gary

Howdy All,

Musiche..Sorry about that. I never heard of Rafflesia, so had to Google..Your plant is Rafflesia. It's very rare, unusual and so pretty.

Purple, thanks for correcting my error. Toni

Toni, I wasn't sure either, just playing along. And I really enjoyed googling pics of what you suggested, a bonus, IMHO!

Actually the credit goes to Eahamel. It was her mention of carrion flower (which would be the common name for this plant, from what I could tell, so it was ID'd when she said that) that helped me find a matching pic, which I wasn't all certain was correctly labeled.

Oh Id love to see a Rafflesia in cultivation!
