Questions about the origin, early evolution, and basal phylogeny of the flowering plants have been areas of ferment in botanical research for nearly 25 years. Rapid progress toward resolving these problems continues to be made, owing, in part, to the unprecedented number of approaches now available, as well as to the accumulation of carefully documented empirical data from both living and fossil plants. During this time, a series of symposia and their published volumes have periodically summarized the progress made and focused research on many of the important issues that remain. The most influential of these publications have beenOrigin and Early Evolution of Angiosperms, edited by Charles B. Beck in 1976, Historical Perspectives of Angiosperm Evolution edited by David L. Dilcher and William L. Crepet as Volume 71, (Issue 2) of the Annals of the Missouri Botanical Garden in 1984, and The Origins of Angiosperms and Their Biological Consequences edited by Else Marie Friis, William G. Challoner, and Peter R. Crane in 1987. We feel that the time is ripe for a new book that summarizes the recent research from fields of paleobotany, comparative morphology, development, and structural and molecular phylogeny that bears on these problems.

The volume took shape at a symposium entitled The Origin, Early Evolution, and Phylogeny of Angiosperms held at the American Institute of Biological Sciences meeting at Ames, Iowa on August 4, 1993. Our contributors were invited because of their ability to provide the most current view of their fields and to place this knowledge into a broad context. In an effort to bring a greater degree of focus to the symposium and to the resulting book, we also asked the authors to consider a set of questions relating to angiosperm evolution. This book follows the same scheme as the symposium with the addition of a geological time scale to aid those who are unfamiliar with stratigraphic terminology, particularly at the level of the epoch and age divisions of the geological periods. As with all efforts to summarize a rapidly developing field, this publication is only a progress report, but one that we hope will serve to further accelerate the process of resolving what seemed only a generation ago to be intractable problems.

Finally, we wish to thank the following reviewers who gave generously of their time to ensure that the contents of this volume met the standards of the science: Pieter Bass, Robyn Burhnam, Peter R. Crane, David L. Dilcher, Jeff H. Doyle, Peter K. Endress, Else Marie Friis, Dorian Q. Fuller, Richard C. Keating, Sergius H. Mamay, Richard G. Olmstead, Robert Ornduff, Edward L.

Schneider, Taylor Steeves, Susan Swenson, Alfred Traverse, Thomas K. Wilson and several anonymous reviewers. Very special thanks are due to Grady Webster who acted as an associate editor for the two chapters co-authored by the editors.
