Very nice flower. As to its status.....I never had any doubt of it being a true species as well as Olaf Gruss in his article in 'Die Orchidee' 02/2021.
Native English speakers read only the 'Abstract' which is written in English.
@ NYEric I uploaded the photo especially for you because I want you to see it without any problems.
My opinion is that this was a natural hybrid that has stabilized in its ecotype and subsequent speciation. The pink pouch is a dominant feature of henryanum and passes on to all its hybrids. Or this could be a variety of henryanum. A DNA study will confirm the relationship in the future.
