Modern angiosperm taxonomy or systematics provides a strong foundation for the progress of biological sciences as it incorporates studies on biosystematics, chemical and serological evidences, numerical taxonomy, cytogenetical and ecological evidences and many others. This book accounts for information on classical and fundamental aspects of taxonomy as well as its recent developments. Special attention has been paid to the chapters on origin of Angiosperms, Theory of Evolution and Evolutionary trends in Angiosperm Flowers. The International Code of Botanical Nomenclature, Important herbaria, Techniques for the preparation, storage and study of herbarium specimens, Botanical gardens, and Taxonomic literature are discussed in detail and includes the study of some selected families belonging to 21 orders. For each family, general features and evidence from anatomical, embryological, chromosome numbers and phytochemical data have been added and evolutionary trends discussed. Attention has also been drawn to economic importance and geographical distribution of these families. Illustrations for some members of these families have also been added.

Deals with biodiversity from evolution and interpretation of evolution as well as taxonomy. The relationships of Plant Systematics to Biodiversity is in the conclusion has an index to Taxa Index to subjects

"The book strikes a balance between classical fundamental information and the recent developments in plant systematics. Special attention has been devoted to the information on botanical nomenclature, identification and phylogeny of angiosperms with numerous relevant examples and detailed explanation of the important nomenclatural problems. An attempt has been made to present a continuity between orthodox and contemporary identification methods by working on a common example. The methods of identification using computers have been further explored to help better online identification. The chapter on cladistic methods has been totally revised, and molecular systematics discussed in considerable detail."--Jacket.

An in-depth look at India's 1,200 species of orchids. The Indian subcontinent--rightfully renowned for its ecological lushness--is home to more than 1,200 species of orchids, about a quarter of which can be found nowhere else on the planet. Fortunately, the Missouri Botanical Garden Press's new book enumerates and carefully classifies each one, following the latest insights from molecular phylogenetic studies. A Checklist of the Orchidaceae of India features typification, synonymy, distribution, habit, and conservation, as well as a key to the identification of orchid genera. The book is part of the Checklist of Indian Plants, a major collaborative project spearheaded by Peter H. Raven of the Missouri Botanical Garden, the Ashoka Trust for Research in Ecology and the Environment, and the Harvard University Herbaria.
