What is this Phal?
 

I am orchid-sitting this for my co-worker and am going to return this to her as a mothers' day present (not the plant but the bloom). Anyway, I am trying to look for its name but in vain. This is a very common phal that we come across daily at stores and orchid shows. Can anybody help me with the name?

Stephen, unfortunately there are about eight billion hybrid white Phals, and this is almost certainly one of them. It would be just about impossible to determine which of the hybrids this one is.
