Still no luck in finding a vendor, Kay. Sorry.
SOLVED: mystery flower
I've been searching online for quite a while with no leads. I emailed a guy who talked about it on his site, from Australia, but he emailed back that he had no source here or in Au.
Top Tropicals does have a few Randias, but not that particular one 8-(
Maybe you could email and ask them if the CAN get this particular one.
