The Stanhopea Book covers the 59 presently known species, one subspecies, the six known natural hybrids of the orchid genus Stanhopea, and two species of Embreea (which at one time were classiﬁed as stanhopeas). An early section to the book gives an overview of the taxonomy of the genus to where we are now. Each of the taxa is treated with a full botanical description, a list of synonyms, reproductions of the ﬁrst description of the taxa and of many of the synonyms, variations within the species, copious illustrations of the taxa using both botanical illustrations and photographs, detailed pictures of the lips and columns in multiple directions, fragrance analysis, pollination information (where known), distributions and registered hybrids.
The general section goes through the complete historic and convoluted history for each of the studied taxa. A section at the back lists the etymology for each species. There are no keys, though the large number of diagnostic pictures identification is easily possible. There is also a section with images of stanhopeas that have not yet been identified; this includes both species and possible putative hybrids. Furthermore, there are sections on hybridization, giving information or listings of all the presently known generic and intergeneric hybrids of stanhopeas, many with pictures; common-sense culture, a complete checklist of the genus and some cladograms. A 22-page bibliography and index round out the work.
