Available in PDF, EPUB and Kindle. Book excerpt: Polyploidy as a dramatic mutational event in the process of evolution has wide implications in nature and for the generation of new and improved crops. The three day Conference on POLYPLOIDY: BIOLOGICAL RELEVANCE focused on three aspects of this natural phenomenon: the first emphasized the characteristics of polyploidy, the second described the occurrence of polyploidy among plants and animals, and the third considered past and future areas of both fundamental and pragmatic research that involve polyploidy. New information relative to origin, cytogenetics, ecology, physiology, biochemistry, and populational studies stress the need to reexamine current views on the origins of polyploidy and its significance among both plants and animals. There are major differences in the occurrence of polyploidy between. plant groups and it is proving a much more common event among bisexual vertebrates than heretofore considered possible. Crop development and improvement must utilize approaches based fundamentally on more natural systems; in fact future research should focus more on polyploidy as a natural phenomenon that needs study at all levels of endeavor from field-oriented populational aspects to sophisticated molecular analyses and genome manipulations. This volume provides a summary of current knowledge of polyploidy pertinent to botanists, zoologists, and agriculturists who are interested in the evolution o~natural systems and who are concerned with the contribution that crop improvement can make to human well-being. Walter H. Lewis St. Louis, Missouri October, 1979 v ACKNOWLEDGMENTS The Host Committee thanks all speakers and moderators for their generous contribution to the Conference and to this volume.

The book includes an overview of the family Crassulaceae and genus Kalanchoe in global and subcontinental contexts that is followed by information on the taxonomic history of the genus. The characters and ecology of the species are also discussed, including their distribution ranges, where they occur, their habitat preferences, and where the species were formally recorded for the first time. For each indigenous and naturalized species, comprehensive taxonomic, descriptive and other information of interest is provided. This is the must-have resource for plant scientists, plant taxonomists, ethnobotanists, herbarium curators, ecologists, pharmacologists, invasions scientists, horticulturalists and landscape designers. - Includes currently accepted scientific names and synonyms, common names in English, morphology, cytology, chemistry, toxicology, biogeography, pollination biology, dispersal, cultivation, biocultural applications, and more - Contains a dichotomous identification key and descriptions, providing much needed tools for accurate species identification - Provides an extensive sets of illustrations for all species

Available in PDF, EPUB and Kindle. Book excerpt: In this volume treatments are offered for 52 families containing 432 genera belonging to 13 eudicot orders, many of which have recently been newly designed; four families remain unassigned to order. Emphasis is on the early-diverging eudicots and basal core eudicots. The wealth of information contained in this volume will make it an important source of reference for both the scholar and the practitioner in the fields of pure and applied plant sciences.
