Hello all,

A recent article in Journal of Ecology (Moran, 1996) presents a study on
pitcher dimorphism and prey attraction in N. rafflesiana. They found that
the pitchers attrack prey by use of UV patterns and a cloying fragrance. 16%
of the lower pitchers and 84% of the upper pitchers produced the fragrance.
Fragrant pitchers caught just over twice as many prey as nonfragrant
pitchers. Moran states that: "As far is known, this is the first instance in
which scent has been proven as part of the attraction mechanism in a
carnivorous plant. Althought some Sarracenia and Heliamphora species produce
scent, its value in the attraction of prey to the pitchers has yet to be
demonstrated."
So maybe this is the same fragrance as smelled by Perry Malouf.

Regards, Mark van Kleunen
