I was talking this over with Ivan Snyder and he claims he's read about
people with alergic reactions to sundew enzymes. Also Ivan has been recently
doing experiments on Ibicella and Proboscidea and he claims at least
Ibicella is only carnivorous in high humidity settings. He claims the plant
will secrete enzyme around an insect or digestible matter in high humidity
meaning that it probably works in the wild like Byblis where it is actively
carnivorous primarily during the morning hours when the morning dew is out.
Jan, have you grown the plant and tested it yourself yet? 2 or 3 experiments
isnt a good deal of testing to conclusively prove something especially if
humidity is a factor which was unaccounted for. I'm not a 'true believer'
that is plant is carnivorous as I might sound but I do think that other
factors need to be accounted for before we draw a rigid conclusion.
