I have a few caudex forming Dorstenias (I call them my HP Lovecraft plants) but I don't have THIS one! Never even found this one while reading online. It's like a cross between a tuberous Aroid with flattened Masdevallia orchid blooms! Wow!
I don't wanna risk that much money though as I've not grown the others long enough to know if I'll kill them or not. Info on growing them is rather scarce and most often contradictory.
But just look at it - it's weird!
