Pankaj Kumar: I think your plant does look like Vanilla shenzhenica except that the labellum is whitish green on outside. In Hong Kong plants labellum is reddish on the outer side. But overall brushy hairs and stiff hairs on the labellum match and so does the flowering period. One more thing, there are 5 flowers on plants in 3921. Vanilla shenzhenica is supposed to have 4 flowers. Not sure if that is a good character.
