The Memorial Hazel Easter Rich Pictorial Guide to Orchids of the Round the Bend Conservation Co- Operative, Christmas Hills and Bend of Islands Region. Hazel and Fred Rich at Round the Bend Conservation Co-Operative. In Memory of Hazel Easter Rich (13th of April 1914 ~ 30th of September 2006) Orchid photographs and text by Dean Rouse. Introduction: Hazel Easter Rich had a great love for the Australian flora and fauna, in particular the Round the Bend Conservation Co-Operative and surrounding regions. She spent many weekends, often with her good friend Ruth Shoebridge, wandering these hillsides and grew to particularly love its diverse flora. A favourite among these were the orchids each species of which would appear for a fleeting few weeks a year. She came to know where each occurred and always looked forward to seeing them again when they made there short but spectacular reappearance. She passed on her knowledge of local orchid sites with all those who accompanied her on her numerous nature rambles. This regional orchid guide is dedicated to her memory and is based primarily on orchid lists for Round the Bend Conservation Co-Operative compiled by Hazel Easter Rich and Dean Rouse (grandson) and the list for One Tree Hill Reserve compiled by Cam Beardsell (Beardsell 2000). Both aforementioned sites are highly orchid rich each having an orchid flora in excess of fifty recorded species and the region as a whole having in excess of seventy species. The regional occurrence of orchid species outside of Round the Bend Conservation Co-Operative and One Tree Hill Reserve, in this guide, is only listed for those species with a highly restricted distribution within the Christmas Hills region. Nomenclature: The orchid names used in this guide follow Jones 2006 with older usage synonyms, or in the case of named hybrids (X) parental species, shown in brackets. Named hybrid species have an upper case “X” proceeding species name. The conservation status of species in Victoria follows that of DSE 2005.
