Dear Wim,

Did anyone test this? How? Anyway, an average tree can also kill all
kinds of animals (if it falls on the head of its victim).

Let us wait and see...

How does he want to test this? With sheep and cows? ;-)

There is AFAIK only the old Mameli stuff (written very early this
century), which is cited over and over again, rather than any
experiment to be done. Therefore, I am very happy to see that anyone
is eager to perform some science with this plant. First of all, try
the film test described to work with _Pinguicula_ by Heslop-Harrison &
Knox (Planta 96:183- 211, 1971) and proved to give negative results
with _Roridula_ by Ellis & Midgley (Oecologia 106:478-481, 1996).
This will show in a very straightforward way if the plant is able to
digest animal protein.
Is the plant identified correctly? There is a significant danger of
confusion with _Proboscidea_. I think _Proboscidea_ was tested for
proteolytic activity already (it did AFAIK not have any digesting
properties). Approx. 90% of the plants sold as "Ibicella" are in fact
only forms of _Proboscidea louisianica_.
Kind regards
