Book Description
An in-depth look at India's 1,200 species of orchids. The Indian subcontinent--rightfully renowned for its ecological lushness--is home to more than 1,200 species of orchids, about a quarter of which can be found nowhere else on the planet. Fortunately, the Missouri Botanical Garden Press's new book enumerates and carefully classifies each one, following the latest insights from molecular phylogenetic studies. A Checklist of the Orchidaceae of India features typification, synonymy, distribution, habit, and conservation, as well as a key to the identification of orchid genera. The book is part of the Checklist of Indian Plants, a major collaborative project spearheaded by Peter H. Raven of the Missouri Botanical Garden, the Ashoka Trust for Research in Ecology and the Environment, and the Harvard University Herbaria.

Book Description
Orchids have fascinated people ever since their discovery by Father of Botany . Theophrastus (370-385 B.C.). They are much loved but little studied as they are the largest, most complex and difficult group with nearest estimate range between 25,000 to 35,000 species in over 800 genera. Majority of orchids known in cultivation are, however, natives of tropical forests of Indian Subcontinent (mainly from India, Myanmar, Sri Lanka, Thailand, Malaysia). The Indian Bulbophyllum, Cymbidium, Dendrobiums, Paphiopedilums, Vandas, etc. contributing to develop high quality hybrids. Indian subcontinent is considered primary/secondary center of origin for Orchids found in phytogeographically interesting North Eastern region. The region one of the hot-spots of the world is the richest Biodiversity center of the Indian subcontinent. The authors have made an earnest attempt on most deserving topic. Bulbophyllum is one of the important orchid genera represented by a number of species in this region. This polymorphic and difficult taxa from taxonomic point of view was treated differently by different workers as the taxa are linked with each other in such a way that separation into smaller groups was difficult due to complexities in the group. The book nicely provides the present Status and Biodiversity of Bulbophyllum and allied genera of India, in general and Northeast in particular with keys to these genera, sections and species that were previously included under Bulbophyllum. This is the first consolidated, revisionary taxonomic account on Indian Bulbophyllum and allied genera. A total of 80 species of Bulbophyllum and allied genera are included in this book. The account is supported by 15 illustrations, 37 plates, and 28 tables. Table 1-28 cover monthly average temperature (maximum and minimum), rainfall, relative humidity (morning-evening), detail vegetative and reproductive phenophase data, phenological calendar etc. The book is also primarily intended for the categorization of the genus Bulbophyllum taking the characters of pollinia, seeds and karyotype studies. Chapter 1: General Introduction, Chapter 2: Biodiversity of Bulbophyllum, Chapter 3: Phenology, Chapter 4: Palynology, Chapter 5: Seed Morphometry, Chapter 6: Cytology, Chapter 7: General Conclusion.

Book Description
Orchids account for a large share of global floriculture trade both as cut flowers and as potted plants, and are estimated to comprise around 10% of international fresh cut flower trade. The average value of fresh cut orchids and buds trade during 2007-2012 was US$ 483 million. In 2012, there are more than 40 countries exporting orchids and 60 countries importing orchids around the world, with the total size of the global trade equaling US$ 504 million. In India, about 1350 species belonging to 186 genera represent approximately 5.98% of the world orchid flora and 6.83% of the flowering plants in India. The publication on “Commercial Orchids” is presented in 15 interesting chapters vividly highlighting the global orchid industry, bio-diversity, conservation and bio-piracy of genetic resources, morphological and molecular characterization of valuable species, breeding approaches for improved genotypes, production of quality planting materials, physiology of tropical and temperate orchids, climate change and its impact on orchid productivity, production technology of commercial epiphytic orchids for cut flower, production technology of commercial terrestrial orchids for cut flower, orchids for pot culture, hanging baskets and tree mounting, medicinal and aromatic orchids, post-harvest management of cut flowers of commercial orchids, value addition and marketing.

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.
