The "Pepper" Orchid

I call this plant my "pepper" orchid, because the flowers have a subtle fragrance of black pepper. I don't know much about this plant, except that the seller said it was an Oncidium. It has a code number, but no name or parentage. I guess that it is a proprietary orchid hybrid. I have been gravitating to orchids with fragrance lately, so I was quite pleased to find one with such an unusual scent.
