Noid Phal-every flower is different!

[calypsoB]

So I purchased this new plant yesterday to make me feel better about my other mite infested plants (one of which might die). I find it very interesting that every flower is a fair bit different in pattern and amount of purple as well as the ripple on the top of the petals. I was curious if anyone might know which plants might be involved in it's parentage? Thanks so much everyone!
