Drakaea concolor, commonly known as the kneeling hammer orchid is a species of orchid endemic to the south–west of Western Australia. It is similar to other hammer orchids in that it is pollinated by a single species of male thynnid wasp using sexual deception. The orchid's labellum is similar in shape and scent to a flightless female thynnid wasp. The kneeling hammer orchid often grows in the same areas as other hammer orchids which are pollinated by a different species of thynnid wasp. The species is only known from a few areas in the far west of the state and has been declared "vulnerable" by the Australian government and "threatened" by the government of Western Australia.
