This book is the most comprehensive listing of all known native orchids, both terrestrial and epiphytic, in Australia to date. Each orchid is listed with a small description, distribution details, details of relationships to other orchids, cultivation notes and an illustration. This book has been treated as a valuable tool for the amateur botanist because it covers all known species and the description which is written so the amateur can easily understand, is generally sufficient enough to identify most orchids. Almost every species is depicted by either a colour photograph or a line drawing.
