Please help me to identify this Oncidium

[var.alba]

Hello everyone,

I recently picked up this little Oncidium at ikea.
Though I'm not really fond of noIDs it's a cute plant and I got it for a steal.
Now I would love to know what I've gathered up to grant it the proper care. : )
I know that with all the hybrids out there it's rather difficult, but reducing the possibilities would be very helpful.
