Stylidium, aka trigger plant is a carnivorous plant endemic to Australia.  Part of flowers and stems have sticky glands that capture and digest insects.  The unique feature of this plant is that the flower possesses an appendage consists of female and male sexual organs.  This appendage is set aside when it's ready to pollinate.  When a pollinator visits the flower, this appendage knocks on the back of the pollinator, covering it with pollens, hence promoting cross pollination.  This plant is a large plant grows up to 1m tall. It can be grown in warm temperate to mediterranean condition.
