I received an answer from my orchid judge acquaintance. He said:

"You must have documentation from the place that you purchased the plant
showing that the parent Paph. vietnamense was legally obtained. From what I
understand, only the first generation has to have proof of legality. After
that, it's up to CITIES to police the matter. So what is "documentation"?
From what I understand, a simple letter from the seller will work."

A dated receipt with my business name/address, showing the customers name
and the plant's name, is pretty much all I can provide to my customers who
buy any of the Ho Chi Minh hybrids. I can state on the receipt that I got
them from Antec.

Is this enough to pass muster at any show or judging station in the US?

AOS judges. I have sent this question to the one of the local judges I
know to see what he can tell me about what is required at my local judging
station if such a plant is set in front of them
