Of course any discussion of what this plant may be is only speculation, but it doesn't look to me like it has any Brassia or Miltonia in it, so it's "pure" Oncidium, rather than one of the complex intergenerics like Beallara or Aliceara. It may be one of the hybrids formerly known as Wilsonara (Odontoglossum x Cochlioda x Oncidium), but as Odontoglossum and Cochlioda have been merged with Oncidium, it would just be Oncidium now.

But as the others said, general Oncidium care should be fine.
