Succulent Plant

Hi,

I'm posting here because I've not been able to identify this plant despite searching with Google. I've also not been able to find the plant from local gardening stores.

The colour's a bit off. The plant should be a bit darker.

 

Hi!
It's a monstrosa mutant form of a Cereus sp.

Thanks. It's interesting to know that it's a mutation.
