A revision of Australia’s hammer orchids (Drakaea: Orchidaceae), with some field data on species-specific sexually deceived wasp pollinators

We are grateful to many members of the WA Native Orchid Study and Conservation Group who have assisted our research on Drakaea over the past two decades, Sue Patrick for line drawings, Paul Wilson for Latin diagnoses and Bill Barker for photos of the type of D. andrewsiae at AD. The late Ron Heberle kindly provided a copy of the late Herb Foote’s photo of this elusive species. Garry Brockman alerted us to his rediscovery of D. andrewsiae. Graham Brown kindly identified wasp vouchers for us. Maps were derived and modified from the Australian Virtual Herbarium. For access to specimens we thank the Directors and staff of the following Australian and European Herbaria: AD, BRI, CANB, HO, KEW, MEL, NSW, PERTH, W. Successive Curators, Directors and staff of the Western Australian Herbarium have helped in numerous ways with our research. Two referees suggested material improvements to the manuscript.
