ID Please
 

Photographed this at Marie Selby garden in Sarasota, FL. Would appreciate ID.

Wow, really cool with those fluffy petals.

I can't really help with the ID, except to say it's not an orchid (wrong number of petals).

A type of passiflora, maybe?

It reminded me of that, but I thought they had a lot more petals usually. There could be types that don't though.

Oh gosh, Rosie, I forgot to check for the obvious clues! Still quite new to all of this. Thanks.

Selby's is one of those places that folks just have to visit. The wealth of Gesneriads, nepenthes is astounding! Of course, they have a massive amount of orchids.
That greenhouse with the waterfall is unbelievable. You can get lost in there, looking around:)

Did you take a picture of the leaves? it would be nice if you could post it maybe we could tell by the leaves.

Regret that is all I got.

can't help with an ID, but I did find a couple pictures of the plant:
