It may be some type of Skeleton Flower. I've seen a couple of those on line lately. The tendrils make it look more like some kind of Spider Lily.
I don't know what that is, although I can tell you that there is a cedar tree in the background... but I asked my botany friend and maybe she will know.
BBad mentioned Orchids resembling female gentalia. Here's another and a link to a couple more. http://1.bp.blogspot.com/_AYwY74fDryU/SpC3DRrlgRI/AAAAAAAATeQ/os28pyHCl6Y/s400/vagina+flowers+16.jpg There aren't nearly as many flowers that resemble the male genitalia.
wierdly enough, orchid is often used as a technical euphamisim for testicle, for example, monorchidism is to only have one testicle. (or, only one descended testicle).
