This work is the first illustrated account of the West Himalayan ferns. The first volume contains an account of 28 fern families and 172 species and 10 hybrids. Volume 2 contains account of 16 families and 164 species and 4 hybrids.

The Himalaya, a global biodiversity hotspot, sustains about one-fifth of the humankind. Nestled within the north-western mountain ranges of the Himalaya, the Jammu and Kashmir (J&K) State harbours more than half of the biodiversity found in the Indian Himalaya. The wide expanse of State, spread across the subtropical Jammu, through the temperate Kashmir valley, to the cold arid Ladakh, is typical representative of the extensive elevational and topographical diversity encountered in the entire Himalaya. This book, the most comprehensive and updated synthesis ever made available on biodiversity of the J&K State, is a valuable addition to the biodiversity literature with global and regional relevance. The book, arranged into 7 parts, comprises of 42 chapters contributed by 87 researchers, each of whom is an expert in his/her own field of research. The precious baseline data contained in the book would form the foundation for assessing current status of knowledge about the bioresources, identify the knowledge gaps, and help prioritization of conservation strategies to steer the sustainable use of biodiversity in this Himalayan region. Given the breadth of topics covered under the banner of biodiversity in this book, it can surely serve as a model for documentation of biodiversity in other regions of the world. The book will be of immense value to all those who, directly or indirectly, have to deal with biodiversity, including students, teachers, researchers, naturalists, environmentalists, resource managers, planners, government agencies, NGOs and the general public at large.

The National Botanical Research Institute came into being as the 13th among a chain of National Laboratories established during April, 1953 under the Council of Scientific and Industrial Research by the Govt. of India for advanced research in fields of specialisation which have a direct bearing on socio-economic, industrial and scientific advancement of the nation. Christened initially as National Botanic Gardens, the nucleus around which the institution took shape under its founder- Director Late Prof. K. N. Kaul, was a large herbarium of Indian flora and a centu- old botanical garden spread over 35 ha of land on the banks of River Gomti in the heart of Lucknow city. It’s a matter of great pleasure and profound satisfaction to me that a Golden Jubilee volume entitled, “Pteridology in the New Millennium” is being published and released during the Golden Jubilee year of NBRI in the honour of Professor B. K. Nayar who laid the foundation of the Pteridology Laboratory of the NBRI, which is now a well equipped laboratory for the study of Indian pteridophytes. Professor Nayar is a holistic Botanist as evident through his contributions and publications in almost all the areas of study of Pteridophyta. The contribution of Professor Nayar towards the development of modern Pteridology and the role of NBRI in it is indeed great and very important. His publications will be valuable for the younger generation of scientists in the field as well as for the more mature research workers and teachers.

This volume compiles the `state of the art' knowledge on several aspects of ``Biodiversity, Conservation, and Systematics". The International Botanical Community recognizes "that plants create the ecological habitat for all terrestrial organisms, and that their management and conservation depend on a good understanding of their taxonomy". Biodiversity is considered as "an immense economic resource". Its conservation and sustainable use ensures food security, safeguards human health, and provides ecological as well as aesthetic and cultural benefits. Systematics, as a fundamental science, serves as a very important discipline for understanding biodiversity. In this volume, emphasis has been laid on the simplest Prokaryotic organisms, the diverse Algae, the "Adaptive Strategies of Bryophytes and the "Diversity in Pteridophytes". There is stress on the importance of Ethnic Knowledge, Botanic Gardens, and Reproductive Biology in conservation. Interesting aspects of `Invasive Plant Species', `Analysis of Plant Biodiversity and Evolution at Genome Level' and `Leaf Epidermal Diversity in Grasses' are discussed. Detailed accounts of the fauna and flora of Punjab have also been provided. Dr. Prithipalsingh is a Senior Reader in Botany in Kirorimal College. He has been teaching since 1971. The areas of special interest in which he is recognized as an expert include, besides Plant Taxonomy, Biodiversity Studies, Ecology and Environmental Biology. He has published numerous research papers in National and International Journals. Dr. Prithipalsingh served on the National Consultation Committee for discussing the "State of the Environment Report of India 2001" prepared by the United Nations Environment Programme. He has completed a project on "Status of biodiversity conservation in Punjab" for the Punjab Forest Department, as a member of the Tata Energy Research Institute team. As a consultant for Biodiversity with “The Energy Research Institute (TERI)”, Dr. Prithipalsingh participated in several World Bank funded research projects of the Uttar Pradesh/Uttranchal State Forest Department. He has obtained first hand information on the effect of 'fire', 'grazing', 'collection of non-timber forest products' and 'natural regeneration', focusing on the ground realities for evaluating the impact of different parameters necessary for formulating “management recommendations”.
