Strange looking flower... what is this?

Can anybody help my identify this flower?
Thank you.

 

a pic of the whole plant would be of assistance.

 

Sorry I only have one pic from my friend. The flower is quite distinctive, I think.

 

Wow that's wierd. Some type of begonia, maybe? Or a fungus? I'm stumped.

 

Hm... Dorstenia sp. (D. turneraefolia?)

 

Thank you very much Lila!!
It should be D. turneraefolia as you suggested.

 

thanks, lila!!

what an INTERESTING flower this one has!! very cool - it's going on my 'want' list...
