Please, what Oncidium is it?????
 

I need your help to determine this Oncidium species from de Bolivia´s yungas (Please sorry for my very bad english). Thank you for your help

Hello and welcome to the OB.
I'm sorry I can't help with the identification but it's beautiful, I really like those vibrant colors. Someone with more oncidium experience will post shortly.

I thought it perhaps was Oncidium sphacelatum, but when I googled that, seems the lip is different ...
hopefully someone will be along who can identify it :)

It is near Onc. pulvinatum.

I think it looks like a hybrid, related to conamara wildcat. Perhaps has some odontioda in it.
