Credit to Richard Millner for finding this plant in 2004. I wanted to find it today and we were fortunate to find Richard's plant in full, stunning, healthy form.
Then went on to find another 50 thriving plants only about 100m away from this original plant.
Amazing day!
Again, these flowers seem to have some yellow at the base of the labellum. In the original sighting (30042), the flowers are pretty old and shrivelled so this detail wouldn't have been visible. So both possibly D. punctata.
