Acknowledgments

I thank my wife and field companion Theresa for patient and observant hours spent hunting elusive Cassinia species in several States. This paper, as for others in the series, was based on examination of specimens borrowed from or consulted in several herbaria (AD, BRI, CANB (incl. CBG), HO, K, MEL, NE, NSW, PERTH, S, W). The Directors, staff and curators of these institutions are thanked for their generosity and patience in making this material available (and in some cases for hosting me on visits to their collections). The Director and staff of CANB are thanked also for their support in providing a congenial place to carry out the research, and for supporting fieldwork in 2003 / 2004. Some of the original research on which this paper is based was supported, many years ago, by a research grant from the Australian Biological Resources Study to the Tasmanian Herbarium. Annette Wilson and Helen Thompson, ABRS, provided invaluable assistance in scanning the illustrations.
