The Hammer Orchid is an unusual plant from Western Australia. The flower is green and yellow with a red labellum. The labellum has a narrow stalk which is hinged and can move backward towards the stigma. The plant produces pheromones which attract male native wasp pollinators that may mistake the labellum for a female wasp. The male tries to grasp the labellum which moves back pushing the wasp into the pollen. Next time the wasp lands on a flower the process is repeating and pollen is transferred to the stigma of another plant. The flowers are produced on straight narrow stems, and flowering is in spring from August to October. The plant produces a heart shaped leaf which has a tile pattern of pale green and darker green.
