5W-W Unknown

Hi,

I found this in bloom in my seedling beds.  It’s a first time bloom.  I have been using an NTT ( N. triandrus Triandrus), and its Cousin another NTT that is white that was sold to me as NTT Var albius (white).  This one opens with a light yellow cup and immediately fades white.  Before I get excited about it, I’d like to know if it is one that is already in commerce.  Here’s the picture.

Any guess or is it one of my seedling.  I have a number assigned to it, but don’t trust the number.
