This is true for the 4 eastern spp., only. Quite recently, JAFFE,
MICHELANGELI & al. (1992) have demonstrated _H.tatei_ to *have* digestive
enzymes (& wax scales...). All _Heliamphorae_ seem to have surfactants
which cause the prey (ants) to drown faster in the pitcher fluid than in
the water of nearby bromeliads or ponds.

Kind regards
