What is it?

[Subrosa]

This is an untagged plant that I got from clearing out Ray's greenhouse. I think it's an Oncidium alliance member. Anyone?

Looks a lot like my Oncidium (know it's not Oncidium anymore, but don't remember the new genus) ampliatum.

I was also thinking Rossioglossum (formerly Oncidium) ampliatum, or a hybrid of it.

yes, absolutely, the rossioglossum ampliatum, i bought one from him the other month.
