Book Description
Coelogyne, a large genus of Asiatic orchids, comprising some 190 species and 12 varieties, is widely distributed from India and Sri Lanka across Southern Asia and the Malay archipelago to the Philippines, New Guinea and the south west Pacific Islands. The Genus Coelogyne: A Synopsis provides a comprehensive account that includes ecology, morphology, taxonomy, distribution, descriptions of each species with habitat and flowering time, and molecular phylogeny. This will be of great interest to growers and collectors as the author provides detailed information on cultivation and hybridisation based on his own extensive experience raising these fascinating orchids. Twenty-three maps, 133 colour photographs, and intricate line drawings of the lips of flowers, a critical identification feature, illustrate the text.

Book Description
ORCHID DIGEST, June 1993 -- "A long overdue roadmap. This unassuming, clearly written book may be the most valuable research tool you could find. ...Webster has done us all a valuable service." Robert L. Dressler, AMERICAN ORCHID SOCIETY BULLETIN, July, 1992 -- "For those who wish to learn more about orchid genera from the hobbyist literature, Webster's study guide should be very useful." A reference book for everyone interested in orchid plants, designed to locate key information more quickly. It features: - Classification of 860 natural genera & 544 hybrid genera, showing the basic structure of the orchid family. - Concise discussion of each natural genus, with major taxonomic changes, geographic distribution & unique features, emphasizing most common features. - For each natural genus, a bibliography drawn from 155 references, including the Orchid Digest, AOS Bulletin & Orchid Review. - A wealth of information in a compact 190 page package, convenient to carry to all orchid events. Order from: Orchid Educational Services, P.O. Box 780701, San Antonio, TX 78278.

Book Description
The subject matter of this text is conference based and deals with the physiology, ecology and management of orchid conservation. It offers information not only to the orchid research scientist, but also to the orchid enthusiast curious about the scientific background to this topic. Interest and support for plant conservation has increased considerably and a great deal of attention has been focused on the plight of members of the orchid family. The development makes it desirable to collect existing information and to consider areas of research.

Book Description
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. 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.

Book Description
This book on “Orchid Biology: Recent Trends & Challenges” reviews the latest strategies for the preservation and conservation of orchid diversity and orchid germplasm. It is an outcome of the Proceedings of the International Symposium on “Biodiversity of Medicinal Plants & Orchids: Emerging Trends and Challenges” held on 9-11 February 2018 at Acharya Nagarjuna University, India. In addition, eminent orchid experts from around the globe were invited to contribute to this book. All chapters were peer-reviewed by international experts. The Orchidaceae are one of the largest families of flowering plants, comprising over 700 genera and 22,500 species and contributing roughly 40 percent of monocotyledons. They also represent the second-largest flowering plant family in India, with 1,141 species in 166 genera, and contribute roughly 10% of Indian flora. Orchids comprise a unique group of plants and their flowers are among the most enchanting and exquisite creations of nature. Phylogenetically and taxonomically, the Orchidaceae are considered to be a highly evolved family among angiosperms. They show incredible diversity in terms of the shape, size and colour of their flowers, and are of great commercial importance in floriculture markets around the globe. Millions of cut flowers of Cymbidium, Dendrobium, Cattleya, Paphiopedilum, Phalaenopsis, Vanda etc., besides potted orchid plants, are sold in Western Countries and thus, the orchid cut flower industry has now become a multimillion-dollar business in Europe, the USA and South East Asia. Besides their ornamental value, orchids hold tremendous pharmaceutical potential. Root tubers of Habenaria edgeworthii form an important component of the ‘Astavarga’ group of drugs in Ayurvedic medicine. It is an established fact that tubers of some terrestrial orchids have been used to treat diarrhoea, dysentery, intestinal disorders, cough, cold and tuberculosis. Some orchids, particularly those belonging to the genera Aerides, Arachnis, Cattleya, Cymbidium, Dendrobium, Epidendrum, Oncidium, Paphiopedilum, Phalaenopsis, Renanthera, Vanda etc. have been extensively used to produce internationally acclaimed hybrids. Yet paradoxically, Indian orchids are victims of their own beauty and popularity. As a result, their natural populations have been declining rapidly because of unbridled commercial exploitation in India and abroad. In fact, some orchids are now at the verge of extinction, e.g. Renanthera imschootiana, Diplomeris hirsuta, Paphiopedilum fairrieanum, Cypripedium elegans, Taeniophylum andamanicum etc. Given the global importance of orchids in terms of securing human health and wealth, this comprehensive compilation, prepared by international experts, is highly topical. Its content is divided into five main sections: (I) Cryopreservation & Biotechnology, (II) Orchid Biodiversity & Conservation, (III) Anatomy & Physiology, (IV) Pollination Biology and (V) Orchid Chemicals & Bioactive Compounds. All contributions were written by eminent orchid experts/professors from around the world, making the book a valuable reference guide for all researchers, teachers, orchid enthusiasts, orchid growers and students of biotechnology, botany, pharmaceutical sciences and ethnomedicine. It will be equally valuable for readers from the horticultural industry, especially the orchid industry, agricultural scientists and policymakers.
