Hi @MattM, I agree that it is probably not D pardina. I didn't think the dorsal sepal looked right for D semilunulata, but the labellum mid-lobe does look good for D semilunalata.
Hello Kai. Your enthusiasm is very good & thanks so much for your sightings. It would be helpful if you gave photos of the leaves, and even the whole plant, and tried to avoid having your hand obscuring much of the plant. Best wishes.
