This was my favorite plant from the whole 2016 show.
I don't usually like the Oncidium-adjacent orchids very much, but this one had a weird depth to the color that I liked. The depth was only sort of capturable in photos. This was as close as I got:
I think what does it for me is the subtle banding across the petals.
I found a Midnight Miracles photo on Flickr; that specimen is darker, lacks the bicolored lip, and although it's difficult to tell the size of the bloom without any context, it looks to me like the flower is smaller overall.
Oncostele Midnight Miracles = Rhynchostele bictoniensis x Oncidium cariniferum (Ref.)
Haven't seen Midnight Miracles in previous years' shows; the most similar previous plant is probably Miltassia Charles M. Fitch x Odontocidium Black Beauty, from the 2012 show.
