Bulbophyllum of Sulawesi is a scientific revision of the 123 species and 4 subspecies of Bulbophyllum that are found in Sulawesi. It contains descriptions of all 127 taxa, and illustrates the majority of them with colour photographs, line drawings, or both. The book is organised into sections according to the latest developments in orchid taxonomy; 24 Bulbophyllum sections are represented in Sulawesi. Keys to the sections and species are provided. There is a chapter on the biogeography of Sulawesi  and chapters dealing with the island's forests and orchid habitats. Unlike many orchid books which are dependent on recycling old material, Bulbophyllum of Sulawesi is the product of original research and fieldwork. This is how 60 of the species in this book came to be discovered during the course of this investigation.
