Book Description
This work follows on from the 1995 publication on European orchids. The atlas is now completed with a second part, containing data on the pollination of orchids of the continents of America, Asia, Africa (including Madagascar) and Australia (including New Zealand).;The first part of the book is adapted from the general account of the previous publication and is extended with chapters on taxonomy and pollinators. The general account deals with such things as the history, evolution, morphology, chemistry and genetics of orchid pollination. The second part gives a systematic account for each continent of all well known details. The text is designed to have relevance for orchid lovers whether professional or amateur.

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.

Book Description
The history of written records of native orchids in Taiwan began in 1857 with a British botanist. After more than 160 years of study by European, Japanese, and Taiwanese scholars and enthusiasts, the list of native orchids increased to more than 470 species, including natural hybrids and varieties. The author exerted extensive e orts to include all known species in this work and arranged them based on the order of subfamilies. Scientific names, synonyms, and relevant references are provided for each species. Many of the species are provided with additional explanations in the “note” section. The uniqueness of this book is the line drawing illustrations which emphasize the structure of the column. In total, 500 figures are presented to accompany the species descriptions. These extensive line drawings were accumulated since 1971 and were mostly drawn by the author. More than that, this book also presents the gynostemium structure of more than 380 species, including the stigma, pollinium, rostellum, and column, in high-resolution color plates.

Book Description
A presentation of over 700 popular orchid species in 104 genera carefully detailed with beautiful photographs and concise descriptions of plants, their distribution and habitats by a well-known author and photographer. Each genus is assigned a separate chapter. Coverage of the most commonly cultivated Asian species including their varieties and cultivars (e.g. in Bulbophyllum 72 species; Coelogyne 33 species; Dendrobium 161 species; Paphiopedilum 58 species; Phalaenopsis 60 species; Vanda 44 species) is exhaustive. The orchids are photographed from their best perspective, individual blooms and entire inflorescence: additionally, many species are also shown growing in their natural habitat. Representative hybrids are included to illustrate how some species have contributed to show-worthiness of various genera, their adaptation to a wider climate range, and easy cultivation. This book is a pleasure to view; simultaneously, an easy reference for the identification of orchid species and it provides a guide on how best to grow them. Nowhere else will one find so many popular species beautifully illustrated in a single volume. A must for everyone fascinated by orchids or with a love for nature.
