On a very general note....if the species was discovered after 1990, it's not likely to be legal, especially if it came from Vietnam. tigrinum was described in 1990, from plants that had been imported before the CITES ban took affect, so they are legal. Paphs coming from countries that are CITES signers are also likely to be legal, like gigantifoilum, which is now available as seedlings and hybrids. By the way, in the SLA newsletter there is an article by Holger Perner about barbigerum varieties and relatives...and he states that they are all (including helenae) being flasked in China at a nursery that plans to distribute them internationally, with full CITES documentation...Take care, Eric
