Comments:-

Contrary to common belief this plant is not carnivorous. Insects attracted by its

smell of rotting meat descend into gaping mouth and down into the bulbous section,

where unable to escape owing to the downward pointing hairs, they become dusted

with pollen. There they remain until the flower begins to die and the hairs become

limp. Released they move onto the next flower and repeat the process pollinating it

in turn.
