So is D.regia from only from one site or or has this been confirmed?
What I mean is, is it know that D.regia grows at several sites, but
those in cultivation are all from the type site, or is only known to
occur at one site and so Eric Green has found a new one?

Well as luck would have, the year I spoke with Dr. Williams my twenty-

three compartments. I've not seen a Nepenthes seed pod in person and
so I don't know if they are alike. But could they be related? Or do
you start to get inconclusive/misleading data when comparing very dis-
similar plants' DNA?
