HISTORY OF VITACEAE INFERRED FROM MORPHOLOGY-BASED PHYLOGENY AND THE FOSSIL RECORD OF SEEDS By IJU CHEN A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2009 1 © 2009 Iju Chen 2 To my parents and my sisters, 2-, 3-, 4-ju 3 ACKNOWLEDGMENTS I thank Dr. Steven Manchester for providing the important fossil information, sharing the beautiful images of the fossils, and reviewing the dissertation. I thank Dr. Walter Judd for providing valuable discussion. I thank Dr. Hongshan Wang, Dr. Dario de Franceschi, Dr. Mary Dettmann, and Dr. Peta Hayes for access to the paleobotanical specimens in museum collections, Dr. Kent Perkins for arranging the herbarium loans, Dr. Suhua Shi for arranging the field trip in China, and Dr. Betsy R. Jackes for lending extant Australian vitaceous seeds and arranging the field trip in Australia.
