Allan Cunningham was Australia's most productive field botanist of the early 19th century. His collections, made on many pioneering expeditions, underpin the description of many hundreds of Australian plants. However these collections were dispersed to at least 30 institutions around the world, and in the process, many lost all or part of their accompanying data. These specimens are still of vital importance to the study of the identity and naming of Australia's plants. This book brings together information on about 9000 surviving Cunningham collections in 28 institutions and matches this against Cunningham's original lists. It will allow many poorly labelled specimens to be more adequately identified as well as providing researchers with a guide to the location of elusive material.
