It's mounted on cork, then I set the cork down into a plastic pot and loosely laid down some dead sphag. Watered twice a week and misted when dry. Grown bright. This blooms 2 - 3 times a year, but the winter blooming is always the most profuse. It's been in bud for ages (spikes take months to develop) and the flowers have been opening since December.
The scent is pretty strong and variable. It's hard to describe, but I like it. It's weird in the way that a lot of Oncidium alliance species are.
This is one of the parents of the famous hybrid Oncidium Twinkle.
