So maybe this is more a question of The Lacey Act instead of a CITES standpoint as it appears that CITES does not care as long as the collection was "legit" and flasks are not wild harvested. Unless any of you know of a species that pollinates and creates flasks all by its self ;-)
If the plants or flask clear CITES then they would likely pass Lacey as far as the "species" is concerned. But if the flasks have ligit CITES papers and later it turns out the original plants were collected illegally then it becomes a Lacey issue after fact.
