The book covers all orchids growing wild in New England, New York and adjacent areas of Pennsylvania and New Jersey; includes an illustrated key to the genera, keys to the species, and a checklist of the northeastern orchids; describes 71 orchid species and varieties, provides a drawing of each, and supplies information on more than 50 forms and hybrids; features 192 full-color photographs of the orchids in their native habitats, along with 71 distribution maps; and suggests where to find the orchids.

"In the year 1957, my wife and I were fascinated when we saw a flower of Polyrrhiza lindenii. We were greatly impressed when we learned that this amazing leafless orchid, the flower of which resembles the ghoulish ghost of a frog leaping in mid-air, was a native of our own state of Florida. We became excited over plans to find one, which we accomplished without too much trouble except for getting our feet wet. The fun we had in finding this species and the photographs we took home as lasting trophies led us from one orchid to another. This was only the beginning of a hobby which was soon to develop into a gigantic effort to find and photograph every species of orchid known to have occurred naturally in Florida, and eventually to publish this book. As years wore on, horizons widened. A second volume on the native orchids of the United States and Canada, exclusive of those species found only in the southeasternmost states contained in this volume, will follow. Many monographs on local orchid flora have appeared throughout the years. The present work has been designed first of all for orchidophiles like ourselves, be they amateur or professional. With the treatises of Morris and Eames and of Correll as basic guides, each genus is described as a separate chapter. Since the recognition of a plant by a technical description and line drawings may be difficult, especially for an amateur, a series of photographs in color has been assembled, which will provide the reader with a greater feeling of familiarity with each species, something we have always wanted to see ourselves. With very few exceptions each species has been pictured in its native habitat. Close-up portraits of individual flowers and such interesting features as roots, fruit, and unusual variations have been included."--

Recent studies have revealed remarkable complexity and diversity in orchid-pollinator relationships. These studies comprise a vast literature currently scattered in numerous, often obscure, journals and books. The Pollination Biology of North American Orchids brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators. This, the second of two volumes, treats the subfamily Orchidoideae with the tribe Cranichideae. This is followed by examination of the seven North American tribes of subfamily Epidendroideae and the single North American tribe of subfamily Vanilloideae. The Pollination Biology of North American Orchids will be of interest to both regional and international audiences including: Researchers and students in this field of study who are currently required to search through the scattered literature to obtain the information gathered here. Researchers and students in related fields with an interest in the co-evolution of plants and insects. Conservation specialists who need to understand both the details of orchid reproduction and the identity of primary pollinators in order to properly manage the land for both. Orchid breeders who require accurate and current information on orchid breeding systems. General readers with an interest in orchid biology. Charles Argue, Ph.D., is a plant biologist at the University of Minnesota specializing in the study of pollen grains. His articles have appeared in numerous journals including the American Journal of Botany, International Journal of Plant Sciences (formerly Botanical Gazette), Botany (formerly Canadian Journal of Botany), Grana, Pollen et Spores, North American Native Orchid Journal, The Native Orchid Conference Journal, Fremontia, and as chapters in a number of books. .

Recent studies have revealed remarkable complexity and diversity in orchid-pollinator relationships. These studies comprise a vast literature currently scattered in numerous, often obscure, journals and books. The Pollination Biology of North American Orchids brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators. This, the first of two volumes, furnishes a brief introduction to the general morphology of the orchid flower and the terminology used to describe orchid breeding systems and reproductive strategies. It treats the lady’s-slippers of genus Cypripedium, subfamily Cypripedioideae, and nine genera of the subfamily Orchidoideae, including the diverse rein orchids of genus Platanthera. The Pollination Biology of North American Orchids will be of interest to both regional and international audiences including: Researchers and students in this field of study who are currently required to search through the scattered literature to obtain the information gathered here. Researchers and students in related fields with an interest in the co-evolution of plants and insects. Conservation specialists who need to understand both the details of orchid reproduction and the identity of primary pollinators in order to properly manage the land for both.

Orchids! No other group of plants arouses such immediate interest. No other plants invoke such a strong desire to know more about them, and certainly no group of plants is in such desperate need of human understanding and compassion; in the northeast far too many of their kind stand poised on the brink of extinction. Orchids of the Northeast is a must for orchid enthusiasts everywhere. Along with innovative identification keys and a glossary of botanical terms, William K. Chapman includes the latest research collected on these fascinating flowers. For instance, to allow for current classification changes, three varieties of Cypripedium parviflorum—yellow lady's slippers—are listed, as well as the recently recognized species of Platanthera huronensis, and Malaxis bayardii, and the proposed Platanthera pallida. The many color photographs in Orchids of the Northeast makes this book a visual—as well as a botanical—treasure.

This book is written primarily for the amateur enthusiast and field naturalist who would like to identify their "find" easily and with the least amount of detective work (that is sometimes the way of more professional books written about orchids). Mr. Munden has kept botanical terms toa minimum and has taken pains to exclude various confusing terms, including authorities for species binomials. This book is for the non-professional who wants to know more about the Native Orchids of Nova Scotia.
