What is the second name of the orchid shown in the picture?

Epiphyte: a plant that grows on the surface of a host plant, deriving nutrients from the air, rain, water (if in the sea), or debris accumulated around the host. It grows on the host only for physical support without otherwise affecting the host negatively.

Heecm, thanks for extra info...always appreciated!

So, a plant that grows in the soil is a terrestrial, lol

I have a yellow oncidium called Dancing Lady by everyone I know. I thought it was the only orchid with that name. I know the white one shown as a variety of ghost orchid.

Heecm, thanks for the extra information
