Lindsey, look at those leaves on the Rhychostylis, they are a lighter gray green color with slight furrows running lengthwise from the base to the tip of the leaf. I think that is typical for a Rhynchostylis.
Also the roots coming out from the plant. Phalaenopsis roots are a bit thinner and almost perfectly smooth. I think those Rhynchostylis roots are a little thicker and tougher in texture. They are similar but different.
If you guys have a Rhynchostylis handy, go check it out!
I was just floored because those flowers looked so large to me! Unless it's trick photography?!
