As is the case with many other rare and sought-after species of plant and animal, Madagascar is one of the world’s prime locations for orchids, which make up the largest family of flowering plants on the island. Madagascar is home to nearly one thousand different species of orchids—which make up nearly ten percent of the island’s flora—nearly nine hundred of them endemic. Orchids are found in almost every habitat on the island, from the mountains to the coasts, and this field guide—the first of its kind, fully illustrated with color photographs and packed with details to aid identification—is an invaluable tool for researchers and ecotourists visiting the island.
A continuation of “The Illustrated Flora of Illinois” series, this volume features Illinois flowering plants. This series is designed to provide a working reference for the identification and classification of all the plant forms found in the state. This series is the first of its kind, as no other study of this sort has been undertaken in any other state, and as such, is an unparalleled contribution to its field.
In his introduction to this volume, Mr. Mohlenbrock discusses some of the terms and procedures used in the identification and classification of the plants. He outlines the life histories and morphologies of some of the representative monocots, and also illustrates some of their habits and frequencies in Illinois. Since these volumes are meant to be used by the amateur as well as the professional botanist, the methods and terms used in the text are explained. The directions for the use of the various identification keys are given so that even the novice plant lover will be able to identify the species encountered. For the uninitiated, a glossary is provided which gives definitions for all terms that might be unfamiliar.
All necessary aids to identification are included in the text itself. The identification keys make it initially possible to classify the plants according to order, family, genus and finally, species and the identifying characteristics of each descending class are given in detail. The morphology of each species is outlined, along with data on frequency of occurrence, related soil and climate conditions and history of past collections, and history of past collections. An illustration showing the more important features of the species in detail is included with the description, as well as a map indicating its geographical locations in Illinois.
This book will be invaluable to students, teachers and professionals; particularly those who are interested in observing the plants in their natural habitat. Those who use it will find it possible to obtain a broad view of changing plant forms as they relate to soil and climate variations throughout the state. And it will provide a delightful diversion for all who enjoy viewing beautiful forms in nature. A walk through the forest will become an opportunity for discovery and appreciation.
This lively examination of the structure, classification, evolution, and ecology of the Orchidaceae will appeal to anyone with an eye for beauty or a bent for natural history. It will provide professional biologists and amateur orchidists alike with a deeper understanding--and a thoroughly new classification--of this, the largest flowering family in the plant kingdom.
The book is richly illustrated, with 95 color photographs and 99 line drawings emphasizing orchid morphology. But in the context of serious orchidology, aesthetic richness is not a superficial vanity. It is the result of evolutionary processes that demand adaptation and reward diversity, and Dressler's exploration of these mechanisms demonstrates how well the orchids have met the challenge, with over 20,000 species, a geographical range from Sweden to Tierra del Fuego, and, at times, as many as 47 different species on a single tree. But both the orchids' success and their profligate beauty are grounded, in part, in their voluptuary nature, and one of Dressler's most engaging themes is the reproductive adaptations, worthy of a Renaissance courtesan, that orchids use to attract, deceive, and manipulate pollinating insects.
The orchid family is actively evolving, providing rich possibilities for comparative study. Yet no one, whether professional or amateur, could reasonably proceed without first addressing Robert Dressler's The Orchids. Its new classification alone, including pollination biology, phyletic trends, chromosome counts, and generic relationships, will stand as a watershed contribution to the field.
A gorgeously illustrated ode to the beauty and significance of orchids—and to those fighting to save these unique plants across the globe.
Until recently, a myriad of lifeforms enriched our lives. In parts of the United States, listening to a nighttime chorus of frogs in the neighborhood marsh was an archetypal touchstone of childhood. Children would search for tadpoles, just steps away from native Lady’s Tresses orchids. Year by year, the chorus became quieter. Today, only a few frogs and orchids remain. Is this the world we want our children to inherit? Do we want orchids to slip through our fingers and, eventually, to vanish?
Philip Seaton and Lawrence W. Zettler have traveled the world over the past three decades, studying orchids—the flagship group for plant conservation. This book is a culmination of stories about the people—young and old alike—dedicated to protecting these remarkable plants from extinction. In the 19th century, vast numbers of orchids were removed from the wild, shipped, and sold by collectors. Today, remnants of these original habitats remain that scientists are striving to protect undeterred by impending climate change. Readers will be taken on a journey into the life history of an orchid (e.g., bizarre pollination mechanisms, risky liaison with fungi) through the lens of science, and how this information is applied to modern conservation efforts.

From the East Texas swamps and forests to the Edwards Plateau canyons and the Trans-Pecos mountains, Texas hosts a surprising number of native orchids. Their exquisite beauty endears them to everyone from wildflower lovers to professional botanists and conservationists.
This beautifully illustrated book presents all 54 wild orchids of Texas. The species descriptions that accompany Joe Liggio's lovely color photos discuss the plant's flowers, blooming season, pollinators, typical habitats, and range (also shown by map), including its distribution within and beyond Texas. The species are grouped by genus and also listed by color, county, and habitat for easy reference.
In addition to the species accounts, the authors offer a general natural history of Texas orchids that discusses such topics as pollination and reproduction, special growing requirements, and threats to orchids from loss of habitats and careless collecting. They also describe the many orchid habitats in Texas and the species that grow in each. This wide variety of information, which has never before been collected in one volume for a general readership, makes this book the essential guide to Texas' wild orchids.
