The Wild Orchids of North America, North of Mexico by Paul Martin Brown encompasses some 239 illustrated species and 49 subspecies of orchids that are found in North America north of Mexico. This flex-cover volume is a complement to Brown's Wild Orchids of Florida (Brown, 2002).
Although Brown does not include descriptions for each species, he does provide keys for all genera and species. Each species is listed alphabetically and references and citations are provided for the reader to learn more about each one.
The appendix includes a section on additions, corrections, nomenclature changes. He also comments on Luer’s 1972 and 1975 monumental works. A checklist with scientific and common names for all species and subspecies is also provided for those who want to keep track of what the reader may find in the field.
A reminder to those who like to hunt for orchids: Take pictures, but leave them in their natural soil—never ever collect any species and leave them for others to enjoy.
