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.

This book is designed to introduce the fundamentals of systematics in a simple, concise and balanced manner. The book aims to equip the students with the basics of plant taxonomy and at the same time also update them with the most recent advances in the field of plant systematics. The book has been organized into 21 chapters that introduce and explain different concepts in a stimulating manner. The text is supplemented with relevant illustrations and photographs. Relevant literature has been added to provide a better picture of the most recent updates in the field of plant systematics.

The basic aim of this manual is to provide useful resource materials for training young students and faculties working in the area of plant systematics. The manual provides updated information on basic as well as applied aspects of plant systematics on various groups of plants like Algae, Lichens, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms. 1 to 3 describe the various approaches and methods to study microbial and fungal diversity, which is basically a very useful precursor to the students and young researchers. 4 and 5 provide deals with the multi-dimensional approaches in Lichen systematics. The book progresses upwards through the plethora of information on the diversity and systematics of Algae, Bryophytes, Pteridophytes and Gymnosperms ( 6-10). 11 to 15 contain on the plant methodological details identification, approaches and methods of Flora, revision, monograph and development of herbarium. This information is very important for the students and young faculties who intend to pursue their researches in plant taxonomy. 14 and 15 particularly provide all the relevant information on the International Code of Plant nomenclature including cultivated plants. These s per se are very significant for the amateur as well as serious readers of plant taxonomy. Plant taxonomy and biosystematics is a dynamic subject, as it derives information from various other disciplines like palynology, seed morphology, pharmacognosy, molecular biology, etc. We have, therefore, broaden the scope of this book by including the s on palynology, seed morphology, molecular systematics, biostatistics, ecological and remote sensing methods for diversity analyses, and pharmacognostical tools for identification of herbal drugs ( 16-22). The knowledge and information on these applied aspects of biology in relation to taxonomy will certainly infuse the interest in readers, who are pursuing plant taxonomy as their scientific pursuits. 23 and 24 describe the various methods of characterization and evaluation of ornamental and medicinal plants. The last (25) of the book provides the information about CSIR-NBRI Botanic Garden and its various repositories, which could be of great interest to the readers from the perspectives of plant conservation.

The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

The reproductive organs and mating biology of angiosperms exhibit greater variety than those of any other group of organisms. Flowers and inflorescences are also the most diverse structures produced by angiosperms, and floral traits provide some of the most compelling examples of evolution by natural selection. Given that flowering plants include roughly 250,000 species, their reproductive diversity will not be explained easily by continued accumulation of case studies of individual species. Instead a more strategic approach is now required, which seeks to identify general principles concerning the role of ecological function in the evolution of reproductive diversity. The Ecology and Evolution of Flowers uses this approach to expose new insights into the functional basis of floral diversity, and presents the very latest theoretical and empirical research on floral evolution. Floral biology is a dynamic and growing area and this book, written by the leading internationally recognized researchers in this field, reviews current progress in understanding the evolution and function of flowers. Chapters contain both new research findings and synthesis. Major sections in turn examine functional aspects of floral traits and sexual systems, the ecological influences on reproductive adaptation, and the role of floral biology in angiosperm diversification. Overall, this integrated treatment illustrates the role of floral function and evolution in the generation of angiosperm biodiversity. This advanced textbook is suitable for graduate level students taking courses in plant ecology, evolution, systematics, biodiversity and conservation. It will also be of interest and use to a broader audience of plant scientists seeking an authoritative overview of recent advances in floral biology.

Plant Biosystematics is a compendium of papers from a symposium titled "Plant Biosystematics: Forty Years Later" held in Montreal in July 1983. This collection reviews the current field of biosystematics, particularly the evolution of natural biota, and how plant biosystematics can contribute to the welfare of humans. One paper reviews biosystematics, compares new approaches, and discusses the latest trend in comparative, molecular evolution of genes. One author discusses the cytology and biosystematics concerning the discontinuities and genetic independence occurring in the evolutionary process. Another author discusses chromosome pairing in species and hybrids that includes models of chromosome pairing in diploids. The text also describes chromosome banding and biosystematics, as well as the problems of chromosome banding that should be addressed to in future research. With estimates of the number of species being threatened with extinction numbering around 20,000 one paper address the issue of conservation and biosystematics. The author suggests that more biological information should be published to avoid duplication of effort, and possibly drive scientists to have their views more widely felt. Agriculturists, botanists, conservationists, environmentalists, and researchers in the field of botany, conservation, and plant genealogy will find this book valuable.
