This book features approximately 210 rare plants within the botanical area known as Greater Sydney. This runs from just west of Lithgow, follows the Great Dividing Range and extends north to Port Macquarie and south to the Shoalhaven River at Nowra.
The body of the book features the rare species themselves, approximately a page per species. They are organised in alphabetical order, each entry consists of at least one colour photograph of the species, a botanical description and notes on its habitat and distribution.
The history of the plant's naming and collection and other interesting facts are also named. Throughout the book there are a number of historical illustrations; some botanical and colourful; other photographs of field trips or famous botanists and collectors.
The plants described include many newly named and quite a few newly discovered species - including the Wollemi Pine. Being rare, many of these species have never before been seen in colour photographs. Some notes on the collectors and botanists who have contributed to our knowledge of Sydney's rare plants are compiled in an appendix. This list has never before been brought together and will form a useful reference for historians and botanists.
