In a complete revision and expansion of his previous work on the subject, Paul Martin Brown incorporates 10 years of additional research and fieldwork in this expanded guide to the wild orchids in the entire Northeast. Now including all of Pennsylvania and New Jersey (a state never before covered in its entirety), the guide spans the region from the southern Pennsylvania border to the northern tip of Maine, and includes features on areas of special interest: the Northwoods (bog, fen, and boreal forest), the Connecticut River Valley, central New York State, metropolitan Boston, Cape Cod and eastern Long Island, the New Jersey pinelands and Cape May, and the Alleghenies of Pennsylvania. Enhancing the text are more than 300 color photos illustrating the orchids, 79 distribution maps, along with regional orchid hunting maps and original paintings by Stan Folsom. The guide covers 79 species and varieties, 88 forms, and 15 hybrids. It provides quick access to locally useful information via state-by-state species checklists, species rarity and conservation information, regional flowering time charts, and a hunting guide that divides the Northeast into regional habitats and hot spots, and a special tribute to the late Philip E. Keenan. Combining the attractive and useful tools of a field guide with additional features for serious researchers, writers, and taxonomists, this is the ideal companion for casual hikers and dedicated orchid hunters alike - a handy, authoritative guide for the northeastern states.
