Possible Oncidium Orchid? with Green, Brown, and Pink
 

I just noticed an unlabeled orchid blooming in our collection in the conservatory I work at. Can anyone tell me what it may be?

Looks like an Encylia of some kind. If it is not tagged, hard to tell if it is a hybrid or species.

Good call. I wonder if it's some kind of Encyclia pauciflora hybrid...

Probably encyclia alata, looks like the sun could have soften its natural colors

or
parviflora; beliezense; or....

That's 100% Encyclia alata. It grows wild here in my country.
