Are signatory countries able to grant export permits to selected other
countries or is it an ALL or none kind of deal.

So if Country "A" has a plant within it's border and declares it to be on
the Appendix I list can it grant export permits to Country 'B" but not to
country "C"

I *think* the answer is no. If you can find the plant for sale in Country
'B" but country 'A" does not allow export, then you can not get legal
permission to bring into Country 'C" from Country "B" or to buy it legally
inside country 'B" or Country C...no matter how it got there. Of course, I
could be wrong.

If country A does not allow it's export, it doesn't matter how the plant is
collected or propagated inside country A, you can't have it if you don't
live there.

If you want to buy a plant from outside your country, make sure you
understand permit requirements; don't count on the vendor to know. If you
find a plant inside your country that you question, check with your
government's CITES office to be sure. Your government's Cites office can
help with both issues.

On the other hand, if you want to express an opinion, you've come to the
right place.

IMHO, a thread with a name like this one was meant to burn. Enjoy it, but
be wary...and bring your thick skin.
