Hi Michell and welcome to Orchid Board.
Your orchids looks gorgeous. I agree fully with Ron that it is Oncidium Alliance and probably has a lot of the Odontoglossum genus in the cross somewhere.
I have lots of orchids without names as do many people here. We call then NoIDs and I like to give mine names I make up myself (just so they don't feel left out from those which have names
)
The main thing is to know enough about what it is to know how to care for it. There are a couple of culture sheets here which are relevant to this one.
AOS | Odontoglossum
AOS | Oncidium
Hybrid Mode
