Oncidium?

[unique562]

I'm not sure what this is but i think its a Oncidium. Its growing new leafs and roots but the old part is doing nothing. I've had it for 2 years and nothing. When I bought it two of the main leafs were cut off. I was just wondering if the old part gets new spikes and blooms or if I should cut it?

Also have a Phal. has not bloomed in 3 years. I have it in a clay pot. I have a tray with water in it for humidity. Anything I can do to help it
