Bernhardt & Weston, The pollination ecology of Persoonia

1985; Bernhardt and Thien 1987; Thien et al. 1994). The Persoonia species of eastern 
Australia have a much more specialised system of pollination and recruit relatively 
few of the many genera of native bees as true pollinators. It is unlikely, then, that 
Persoonia sens, strict, can be used as a specific model to predict ancestral modes of 
pollination in the Proteaceae. 
Acknowledgements 
Research was funded by two Fellowships to P. Bernhardt (1990-1992 and 1994) 
provided by the Royal Botanic Gardens and Domain Trust, Sydney. We would like 
to thank John Myers for drawing Figs 1, 2 and 6. Particular thanks are expressed to 
Ms Natasha Baczocha, Mr T. Hawkeswood, Ms Denise Day, Ms Catriona McPhee 
and Dr K. Walker who assisted in the collection and preparation of insect specimens 
and helped to record data over three seasons. Drs B.G. Briggs, S.L. Krauss, G.V. Maynard 
and Peter Wilson provided helpful comments on the manuscript; we remain 
responsible for residual deficiencies. We gratefully acknowledge the advice, 
encouragement and pioneering research of Dr L.A.S. Johnson on the Proteaceae and 
on Persoonia in particular.
