India has a vast landmass of 328 million hectares, extending from the tropics to the alpine regions, rich wetlands to deserts, islands, long coastline to Western and Eastern Ghats and the high Himalayas. It has equally rich and diverse plant diversity, with over 47,000 species that are already documented. Because of the large population dependence on these plants, expansion of agriculture, urbanization and development efforts, many species are threatened too. Some of the issues concerning plant diversity in India are unique to the country. Taxonomic and floristic studies on all major groups have been carried out but the information is scattered in research papers and regional/local floras, manuals and monographs. This volume intends to bridge this gap. Nine of the thirteen chapters of this volume deals with different plant groups extending from algae to angiosperms and allied groups such as bacteria, fungi, lichens, and myxomycetes. There are chapters dealing with topical issues in global context on biodiversity with special reference to India such as climate change and its impact on biodiversity, crop diversity, and tradomedicalism. Each chapter is written by author(s) specialising on the particular group and having long experience of research in it. Each chapter includes not only distribution and diversity but also major researches, economic uses and conventional human interactions. Lacunae in current knowledge are also pinpointed. The book provides information on ecosystem diversity, flora of special sensitive regions (mangroves, wetland, and coral reefs), and on policies and strategies being adopted for in situ and ex situ conservation.

This book addresses the resurgence of interest in the rediscovery of ethnomedicinal plants as a source of potential ethnomedicines. In the 21st century, the pharmacological effects of medicinal plants are considered to have a promising future as drugs and medicines for the management of healthcare. Considering the extremely high cost and length of time needed for the development of new drugs, as well as the high drug attrition rate, pharmaceutical companies and researchers continue to explore new ways for drug R&D and focus more attention on the benefits of ethnomedical plants as a source of new compounds for drugs. The research provided in this timely volume examines the development and characterization of new natural drugs from medicinal plants with the aid of better screening methods. The chapters survey specific medicinal plant species and describe the characteristics of each, how the plants work, and their applications for healthcare. The authors provide research on plants from Western Ghats and adjoining areas for ethnomedicinal investigation because this area is very rich in phytodiversity and tribal traditions in phytotherapy and the plants surveyed have applications beyond this region. This book is a valuable medical compendium of plants and is intended as a guide and reference resource for professionals in the field. It reviews the current status of ethnomedicinal plants research in light of the surge in the demand for herbal medicine as a future source of new therapeutics.
