I got this from Andy's Orchids in 2014. It isn't showy, but the details are interesting. Here is the link to my Orchid Borealis blog post.
As with the other Porroglossum, the lip moves rapidly to trap the pollinator (video in the blog). So it took a long time to take photos of dissected view (more in the blog). When I cut off the sepals, the lip closed, and I had to wait about one hour to take photos showing the natural lip position.
While I was prepping for the post, I learned that this kind of actively motile lips evolved multiple times independently within Pleurothallids.
Lip open in a natural position:

Lips are triggered and closed:
Sepals are removed, and you can see the small petal and the lip hinge.
