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.

Some of the important chapters in Part I comprise Different Classifications, Nomenclature, Biosystematics, Modern Trends in Taxonomy, Chemotaxonomy, Numerical Taxonomy etc. Part II deals with about 214 families of which 55 are discussed in detail and summarized accounts of the rest are given for advanced students. The book also comes loaded with numerous appendices like comparison of classifications, floral diagrams and floral formulae, questions etc. The book will cater to the needs of Botany students pursuing B.Sc. (H), M.Sc. and related fields like Medical Botany, Pharmacy, Agricultural Botany and Horticulture.

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.

Angiosperms are the most diversi ed plant group in the world, being represented by ca 300,000 species in about 400 families. Like all of Life, including ourselves, they have had their own history and gone through many evolutionary stages before they arrived at their current forms. The origin of Angiospermae ( owering plants) has been the subject of much dispute because this is a key event in the history of life, and has a far-reaching in uence on our understanding of relationships among seed plants as a whole as well as within the angiosperms. Until recently most of palae- otanists recognized angiosperms only from the Cretaceous and younger strata. This contradicts the results of molecular analyses. I have been working on Mesozoic fossil plants for the past two decades, during which time I have studied a number of fossil plants. Some of these fossil plants have been published as Jurassic angiosperms, and, unsurprisingly, many questions and doubts have been raised about them. These questions need to be addressed se- ously and journal papers do not provide suf cient space to compare and relate these early angiosperms. In this book these pioneer angiosperms are documented in detail, sometimes with new specimens not studied before. Also, I propose a de nition of angiosperms that could be adopted in palaeobotany. My aim is to improve clarity and objectivity of judgment about what constitutes a fossil angiosperm.

COMPARATIVE EMBRYOLOGY OF ANGIOSPERMS is a review of the developmental processes leading to sexual reproduction in flowering plants. On the basis of embryological data and certain evidences from other areas of study, it lays special emphasis on the relationship among and within the families and orders of angiosperms. Occasionally, inaccuracies in observation and interpretation are pointed out, alternative interpretations offered, gaps in our knowledge highlighted, and prospects outlined. The text is documented with 36 tables, 376 figures, and about 5000 literature citations, which contribute to making this book comprehensive. Besides students and research workers interested in angiosperm embyology, taxonomists, plant breeders, agriculturists, and horticulturists will also find much useful information in this treatise.

For the first time in synoptic form, this book presents a clear account of the most recent knowledge of embryogenesis in flowering plants. A multidisciplinary approach is adopted bringing together the foundations of tissue culture, biochemistry, and cell and molecular biology which have supported the rapid progress of research in angiosperm development. In the first part of the book, the author draws a broad picture of the processes involved in embryogenesis. A brief introduction to procedures is followed by chapters on developmental, cellular, biochemical and experimental aspects of embryogenesis, and on somatic and pollen embryogenesis. Later sections on the regulation of gene expression and mechanisms of programming developmental information precede a treatment of some practical applications resulting from the study of embryos. Two techniques discussed which are aimed towards the goal of enhancing crop productivity in a dynamic and expanding field are embryo rescue from inviable crosses and preservation of germ plasm.
