White bifoliata Cattleya

[Pep]

Good afternoon,

I have attached a couple of pictures of a Cattleya bifoliata that i have at home. It was a present and there was no tag involved, so that i don´t have a clue about what kind of hybrid might it be. I only know that is a bifoliata that sometimes flower twice a year, june and october.
Now is resting from last repot (roots growing then) and i think its stablished, pseudobulbs are not shrinking, spray daily and water when dry. I expect new activity soon as with the day light growing, i have notice new green root tips in other cattleyas i have.
Any one has an idea that what kind of Cattleyas are behind?
Thanks in advance
