I will be attending the conference and look forward to lively debate and
CP evolution brainstorming with you over sundew cocktails ( 70% ethanol,
30% sundew extract :-)

As I have told you before Jan, I do not mean to challenge you. We should
not quibble over minor differences. Our beliefs in this matter are
basically the same. I hope my observations will be helpful / useful. It
looks to me as if the styles of most drosera are built for movement. They
bend to make contact with stamens, and not as a consequence of withering.
I have witnessed flowers close immediately upon pollination, but am not
certain this was not just a coincidence. Question: what do stigmas exude
in response to pollen, any enzymes?
