Interesting article in September 2014 AOS Orchids. Seems several plants have been presented for judging labeled as Paph. chiwuanum or Paph. hirsutissimum var. chiwuanum. Article has several photographs for illustration. "The fact that several plants have appeared almost simutaneousle suggest that they are part of a larger seedling population that is reaching flowering size. These are not Paph. chiwuanum and are, in fact the hybrid of Paph. hirsutissimum and Paph. henryanum registered in 2002 as Paph. Frank Zettle." Main distinction is in the staminode. Same article Holger Perner "pointed out that another hybrid is making the rounds selling for hundreds of Euros on the European market and likely to show up here as well. This hybrid. Paph. Hans Strahl (Bidborough x hirsutissimum looks like a "giant" or polyploidy strain" Moral of the story is to watch what you buy and from whom. If it is a nice flower enjoy. Just label it correctly.
