This textbook presents a comprehensive treatment of Angiosperms by discussing its vital components, Taxonomy, Anatomy, Embryology including Tissue Culture and Economic Botany. Written in a simple and lucid style, it has abundance of relevant illustrations with self-explanatory diagrams. Information on new angiospermic families enhances the utility of the book. It caters primarily to the requirements of undergraduate students of Botany and would also be a useful source of reference for postgraduate students & candidates appearing for several competitive examinations.
Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.
The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

Taxonomy is one of the oldest biological disciplines. This book presents an account of general principles and aims of taxonomy in a comprehensive manner. It has been written mainly to cater the needs of undergraduate students pursuing courses in Botany/Life Sciences/Plant Sciences, but it will be useful for postgraduate students of these disciplines as well. The book gives a critical account of the important systems of classification and salient features of the APG II (Angiosperm Phylogeny Group, 2003) system of plant taxonomy. It mentions the important rules of plant nomenclature, and various codes of nomenclature including the latest Vienna Code of 2006. Further, it discusses the usefulness of anatomy, embryology, palynology, chemistry, cytology and ecology under current trends in plant taxonomy. A thorough coverage of profusely illustrated 50 important dicotyledonous and monocotyledonous angiospermic families is the hallmark of this book. Each family is described covering the following points: Distribution, vegetative features, floral description, morphological nature of organs, further classification, affinities with other families, economic importance and description of common plant(s). Finally, the book covers the different aspects and theories related to the origin of angiosperms, and elucidates the methods and techniques of herbarium development and maintenance. KEY FEATURES: Presents a key to families described in the book. Provides a pro forma for the description of angiosperms. Includes a glossary of important technical terms. Lists the important Herbaria of India and the world.
Reproductive Biology of Angiosperms: Concepts and Laboratory Methods will cater to the needs of undergraduate and graduate students pursuing core and elective courses in life sciences, botany, and plant sciences. The book is designed according to the syllabi followed in major Indian universities. It provides the latest and detailed description of structures and processes involved in reproduction in higher plants. The inclusion of colour photographs and illustrations will be an effective visual aid to help readers. Interesting and significant findings of the latest research taking place in the field of reproductive biology are also provided in boxes. At the end of each chapter, the methodology of hands-on exercises is presented for the implementation and practice of theoretical concepts.
