UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type o f computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.

Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back o f the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6” x 9” black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

ACKNOWLEDGMENTS Of all those I owe thanks to, I must first acknowledge my graduate committee for their time, critical comments, and encouragement throughout the stages of my program. I thank my thesis director, Garrett Crow, first for suggesting the taxonomic dilemma in Nuphar as a viable project, and then supporting its study, granting me much'academic freedom, workspace, professional advise, and the opportunity to collect in Siberia. His comments and criticisms have all been beneficial. Linn Bogle has been instrumental in my program over the years, providing books, literature, lab space, supplies, numerous technical and professional advice, and enduring my benign sarcasm. Tom Philbrick, Janet Sullivan, and Tom Lee all have offered sound advice, constructive criticism, technical review and support relating to the dissertation. I am very thankful to Don Les for “adopting” me into his laboratory at UConn and introducing me to molecular systematics m situ. I am grateful for the technical training, use of his laboratory facilities, professional advice, constructive criticisms, and for recognizing the better things in life; waterlilies and a sense of humor. I am appreciative of Barre Hellquist for all the help over the years, for sharing his overall experience with this genus, assistance in field collecting, but most importantly for allowing me to stay dry on aquatic plant excursions. I am indebted to my friend and colleague, Michiko Shimoda, for innumerable correspondences and research assistance over the past few years. She has provided me with living Japanese Nuphar. tissue samples, photographic slides, literature, english translations, and various opinions. I am thankful for her sincere interest in my studies of Nuphar. Much of my understanding of Japanese Nuphar is largely due to her cooperation. i v Reproduced with permission of the copyright owner.

Thanks are owed to John Wiersema for help in the field, nomenclatural advice, critical readings of earlier drafts of Chapter 3, and for providing live material of N. polvsepala: Ed Schneider for morphological data on Barclavaand providing photomicrographs of pollen; Jianhua Li for friendship, the many discussions, translations of Chinese literature and specimens, and for sharing computer time and lab space; Nur Ritter and Eric Hellquist for friendship; and Naoko Shibata and Mari O’Connell for translations of label data of Japanese specimens. Other associates at UConn who need to be acknowledged include: John “PCR” Gabel for friendship, protocols, providing outlets for my humor, and occasionally a place to sleep; Ron ‘Milfoil” Aakjar for friendship, lab favors, and various technical advice; Les Mehrhoff for assistance and gossip; and Maryke Cleland for instructing me on molecular techniques. I am indebted to the various organizations willing to endorse my studies. Without their support, the direction and results of this work would scarcely mirror its present form. I am grateful to the International Water Lily Society for their continuous support of field and laboratory research on perhaps one of their least favorite Nymphaeaceous genera; the New Hampshire Agricultural Experiment Station for research support; the National Geographic Society for providing the means to allow me to conduct field work in Asia; the Barbara J. Harvill Botanical fund for supporting fieldwork in Virginia; and the UNH Graduate School for providing monies for materials and travel to meetings. I am grateful to all others who have provided various data, opinions, interpretations, literature, and or allowed access to herbarium or living collections, including E. Schuyler (PH), Y. Kadono (Kobe University), N. Nickerson (TUFTS), T. Jennings (Longwood Gardens), and staff at The New York Botanical Garden and the Gray Herbarium. I must specifically acknowledge Noel Holmgren and Wayt Thomas for providing work space and various resources at NYBG. V Reproduced with permission of the copyright owner.

Much gratitude is extended to my family for supporting my obligatory “perpetual student” lifestyle over the years, and for providing more times than I’d like to admit food, shelter and clothing. I would like to especially thank my mother Elaine for long nurturing my interests in biology and aquatic plants, and for bearing with my weekend (and long­ distance) pond-keeping. A supportive family made the long haul a bit more forbearing. Finally, I am grateful to my wife and friend, Kathleen McCauley, for her advice, assistance in field collecting and herbarium management, and for being tolerant of and enduring my more than occasional absences. The weight and burden of completing this degree has surely been bore by her as much as it has been by myself. Since my early days in graduate school, I have surely been blessed with her love, companionship, and enrichment. I thank her from my heart for rounding my edges, and allowing me to imagine every inch of my dream. This dissertation is dedicated in memory of Frank Ellison, Sr. Though only graduating from the “School of Hard Knocks”, his encyclopedic knowledge was something no higher degree could ever parallel. I only wish he could have seen this work come to fruition. v i Reproduced with permission of the copyright owner. Further reproduction prohibited without permission. “Many people find the
