Ormerod Paul:

The plant pictured here has pink flowers, large obovate lip, and seemingly no visible callus. This seems to be a spectacular undescribed species. True D. hamatum has yellowish white flowers with purplish or reddish stripes, and large callus (shaped like the bow of a boat) on the lip. There is a very similar taxon in Borneo called D. hamaticalcar, if you want an idea of what true D. hamatum looks like, plus there is a watercolour sketch on the type sheets.
