According to what I have seen about cloning and mericloning nepenthes, the embryo of a seed has the best chances of replicating istelf than any other growing point on the plant. the seedling cells multiply and divide easily invitro and can be divided into smaller cells that divide and replicate itself well. The problem is that most of the time, a plant that is TC from seed has unknown adult matured characteristics than if taken from an adult mature plant showing characteristics that we'd like to see in plants desired. This is why you don't see any N. Trusmardiensis in TC or even a hybrid like N. Predator. But if one is to remake the cross of Predator (N> truncata by hamata) then we could anticipate the result of the developing seedling when mericloned for replication. But the final result of what you cloned is totally unknown until a sample of that batch is grown to semi-matured characteristics. Like Red Leopard. I believe N. Miranda was one of several clones grown from seed invitro and then tc for massed replication. It appears that N. Miranda originated from DeRoos in Denmark, so the clone must have originated in Europe. I also believe that DeRoos also purchased experimental clones invitro from Malesiana and some still bears the MT clone numbers starting with NE (i.e. N. tobaica and N. Ventrata...which DeRoos sells as N. alata). They are having nursery management problems at the moment and other internal problems with regard to reliable professional help, so they had intended many more nepenthes to be grown, they've lost countless tens of dozens of clones in transit and disappearance from lab to nursery.
Or possibly espionage theft to keep certain clones from becoming widespread as N. ventricosa, truncata, Gentle, Miranda, Coccinea, alata (Ventrata), tobaica, Judith Finn, rafflesiana, and sanguinea.
More later on the subject when a post is out on this topic specifically.
