Are you saying that these plants are better preserved in private collections
than in the wild?

Why do you need more genetic diversity? For conservation programs, yes
preservation of genetic diversity is a concern. But we have not been
talking about conservation programs, and hobby/commercial growing is not
conservation.

Not likely to be rapidly evolving in nature. Better results can be obtained
by irradiating tissue culture callus.

Well, If the plants don't enter a conservation program geared for
reintroduction then I'm not so sure they are "saved". More like "not wasted"
in my opinion.

Ah em. Lets say I'm more a conservationist than a grower, if you want
a label.

I believe that Nepenthes were very popular Wardian case plants in the
Victorian era. Many of these fell out of cutivation when the fad passed.
Recently people have been here discussing carnivourous bromeliads. Many
people said they used to grow them, their plant died, now where can you get
them? Who is monitoring these cultivated populations? If a plant is not
profitable it won't continue to be propagated by nurseries, and will only
be disseminated slowly from grower to grower...

I don't suggest the plants are impossible to grow, but rather that hobby
collections are not a safe habitat for the plants. Sure you could ask
your friend for a cutting, but what if his died? More importantly, if
you were to die, or become incapacitated, what would happen to your entire
plant collection? How many growers on this list have a contingency
plan to protect their collection if this happens? We are all mortal.
