Funding Acknowledgements

This study would not have been possible without the insightful discovery of putative cryptic orchid taxa by Dr Col Bower. We also thank him for generously sharing his knowledge of orchid and pollinator locations. Dan Ebert, Christine Hayes and Monica Ruibal provided expert laboratory assistance, and Ryan Phillips offered insightful comments on the manuscript. This work was supported by funding to R. P. from the Australian Research Council projects DP045137, LP098338 and DP1094453.
