Grass Trigger Plant

Trigger plants have a fascinating pollination mechanism where the the long reddish "trigger" is stimulated by a foraging insect to flip across the flower and dump pollen on the back of the insect. Gently tickling the centre of a flower with a piece of grass can often set the trigger off.
The plants are a perennial herb with a thick tuft of leaves, giving the whole plant a grass-like appearance, hence the species name of graminifolium. They are a common summer flowering species in forest habitats at all elevations.
