Dear Bill (and all involved in the production of fruit in this fantastic accomplishment/event!),

I don`t know why this most important note on aroid reproduction seemed to have ''slipped through the cracks'', but I put it aside to talk about it on week ends when I have more time.
There is a paper published on the freezing and refrigeration of mainly Amorphophallus sps. pollen, and the times that it remained viable when thawed and then used--for the life of me I can`t locate it at this moment.
This report of A. titanum pollen from Bill`s baby ''Trudy'' which had been kept frozen at -80 deg. F for that length of time, and which was sucessfully thawed and then used to produce that magnificent infructesence at UC Berkeley certainly would be good material for a short note in Aroideana!   Think about it, Bill!   
Aroid folks like Bonaventura might get info. from an article like that.

Jim Symon would be SO proud to see his ''grandkids'' (or "great-grandkids"?) developing, actually they look NEARLY ripe!
