Hi John,
Your comments are interesting to me. This summer I made about 50 tests on
Ibicella, plants which are accepted as carnivores, and a series of
noncarnivorous control plants.
My results were straightforward....
1)Drosera, Pinguicula, Dionaea, Drosophyllum all released enzymes.
2)Control tests and tests on non-carnivores showed no enzyme release.
3)Tests on Ibicella lutea and Proboscidea parviflora revealed no enzyme
release, although some emulsion damage was evident by the sticky glands
tearing emulsion.
I have described my results in an article being published in Carnivorous
Plant Newsletter (Meyers-Rice, 1999, submitted), but the basic results are
as I summarised above. In that article I also explored the possibilities
of other (unlikely) modes of carnivory.
Jan Schlauer was also unable to detect any enzymatic activity in Ibicella.
In summary, I can find no evidence that Ibicella is enzymatic.
