I think we are about to open another pandora box!.
Seeds, as far as the laws of Australia are concerned, yes there is a legal trade. however, the individual laws of each country may vary, thus, collection of seeds for example of a new variety of N. rajah recently found, is illegal in Malaysia. Thus the moment a seed collector collects the seed from this particular plant is breaking the law in Malaysia, but if the seed
gets to Australia and passes the quarantine inspection, then there is no problem here.
BTW, this is not the typical rajah so it should not be on CITES list 1 nor 2!.
So the question remains, who is breaking the law and who isn't?
