Yes its Peristylus densus
While taking orchid pics please dont forget to take a pic in a way that it shows the front of flower, spur, whole plant, orientation of leaves and size of plant along with a good closeup from front and side of flower.
This really helps in proper identification.
Just a friendly question?
Now some one tell me why this plant is not Peristylus richardianus?
