Aquatic and Wetland Plants of Southeastern United States: Dicotyledons

Preface

Preface This treatment of dicotyledonous aquatic and wetland flowering plants of southeastern United States is a companion work to our treatment of monocotyledons.* The geographic area of coverage includes North Carolina, South Carolina, Georgia, Florida, Tennessee, Alabama, Mississippi, Arkansas, and Louisiana. This area abuts the eastern boundary of the range encompassed by Donovan S. Correll and Helen B. Correll, Aquatic and Wetland Plants of Southwestern United States (1972). The senior author began research on this work more than twenty years ago at Florida State University with a grant from the National Science Foundation (G-4321) for study of aquatic plants of Florida. Later, funding was obtained from the Institute of General Sciences, National Institutes of Health (RG-6305). While these grants were in force much field exploration was accomplished, voucher specimens were collected, illustrations were prepared, and preliminary drafts of keys and descriptions for some taxa were written. From 1963 to 1973, owing to changes in the senior author's departmental duties at Florida State University, further research was restricted to field exploration and collection of voucher specimens. Duplicates of the specimens were exchanged with numerous institutions, chiefly those in the southeastern states, so that the specimen holdings of the university herbarium were very significantly augmented and diversified. Upon his retirement from Florida State University in 1973, the senior author became a Beadel Research Fellow of Tall Timbers Research, Tallahassee, and research on the project was reactivated under its auspices. The junior author, then in residence in Tallahassee, vigorously encouraged renewal of the effort, with expansion of the geographic area of coverage and inclusion of wetland plants, and her collaboration in the project began. Whatever degree of success may be attributed to our completed contribution, a very large measure of credit goes to Tall Timbers Research, for providing the senior author with a research fellowship, aid of staff (particularly in the onerous task of final typing of the manuscript ), use of physical facilities, and, not least, the stimulative interest of the former and present directors, E. V. Komarek, Sr., and D. Bruce Means. The Department of Biological Science, Florida State University, very generously provided work space in its herbarium for the senior author after his retirement and encouraged him to continue using all herbarium facilities. Much appreciation is expressed to the Department of Biology, University of Southern Mississippi, for its support and encouragement of the junior author's participation during the last six years. To Grady W. Reinert, Barbara Culbertson, and Melanie Darst, artists who drew the illustrations under our supervision, we express admiration for their talents and appreciation for pleasurable associations. We gratefully acknowledge the privilege of using plates from the following publications: Clyde Reed, Selected Weeds of the United States (1970), Elbert E. Little, Jr., and Frank H. Wadsworth, Common Trees of Puerto Rico (1964), Elbert E. Little, Jr., et al., Trees of Puerto Rico (1974), Fred J. Hermann, Vetches of the United States, U.S. Dept. Agr., Handb.
