Moriuchi for constant support, editing, and help with idea development. I thank T. E. Miller, F. C. James, S. J. Steppan, D. Houle, W. Parker, A. A. Winn, C. T. Lee, D. Richardson, M. Rejmánek, S. L. Halpern, J. Hereford, C. Oakley, K. Rowe, and S. Tso and for helpful comments on the writing and idea development. Special thanks to T. E. Miller for lab support, idea development, and constant encouragement, and to S. J. Steppan for training in molecular techniques, lab support, and systematics training. K. Burks provided valuable advice on the choice of the Commelinaceae for this study. R. B. Faden at the National Museum of Natural History, Smithsonian Institution provided plant materials and species trait and range information. M. E. Harris at California State University, Northridge and H. Gamper at Florida State University also provided live plant materials. L. Anderson helped with specimen localities for collection. L. Csiba at the Royal Botanic Gardens, Kew and J. C. Solomon at the Missouri Botanical Gardens provided DNA extractions. T. Evans provided sequencing advice and primers for Tradescantia, and S. Bergamo provided sequencing advice and plant materials for Callisia. C. Hardy at University of Zurich suggested the use of 5S NTS. R. Dhanarajan and M. Asher cloned the 5S NTS region. T. Flanders provided useful information on Commelina benghalensis distributions in Georgia. S. Braun and C. Hess helped estimate rates of spread for introduced species. K. Grafius-Ashcraft and C. D. Smith assisted with soil preparation. B. Nomann assisted with harvesting plants in the greenhouse. T. Knight provided code for the matrix model analyses, and E. Bruna, N. Underwood, and B. Eldred provided analysis advice for this part of the study. S. Park, A. Brodie, and E. Gonsalves helped collect specific leaf areas. This study was funded by Florida State University's Robert K. Godfrey Endowment Award for the Study of Botany, Young Scholar's Program, Dissertation Research Grant, Margaret Menzel Award in the Department of Biological Science, and University Fellowships. Additional support was provided by the Florida Exotic Pest Plant Council Research Grant Award and the National Science Foundation (DEB 0091776 to T. E. Miller). iii TABLE OF CONTENTS List of Tables ............................................................................................................................... v List of Figures .............................................................................................................................. vii List of abreviations ....................................................................................................................... ix Abstract ....................................................................................................................................... x INTRODUCTION ....................................................................................................................... 1 1.
