Mystery Oncidium
 

I bought this rescue orchid last Fall. It was a single pseudobulb in a 2" pot. I assumed it was in the Oncidium family. It is starting to bloom now, and I wondered if anyone has a clue as to what it might be.

Might it be a Miltonia? The green and purple on the sepals reminds me of a Zygopetalum, but the flowers aren't that large and there isn't any fragrance.

I think it's an Odontoglossum.

Not that I am all that knowledgeable, but I have the exact same one here, and that's what it was sold as. - That's all that was on the label tho.

Bil, yours has that purple green mottling too? The closest photo I could find was of a Miltassia.

Where? The sepals are very different to the rest of the flower, almost grey. I'll try and remember to take a pic tomorrow.
If I don't post, remind me please.

The sepals are sort of a mottled green and purple.

It's truly lovely whatever it is :)

It looks kinda like Odontonia Pacific Paranoia 'Other Side of Cool'

A bit like the Miltassia Dark Star. That would be nice!

What ever it is, it's a very pretty flower!
