The Botanical Society of America Merit Award

The Botanical Society of America Merit Award is the highest honor our Society can bestow. Each year, the Merit Award Committee solicits nominations, evaluates candidates, and selects those to receive an award. Awardees are chosen based on their outstanding contributions to the mission of our scientific Society. The committee identifies recipients who have demonstrated excellence in basic research, education, public policy, or who have provided exceptional service to the professional botanical community, or who may have made contributions to a combination of these categories.


Requirements for Nomination

The selection of awardees is driven by nominations from the membership. Nominations should include: (1) a formal letter of nomination including a clear statement of (a) the notable accomplishments of the candidate; (b) disciplines that have been significantly influenced by the contributions of the candidate; (c) letters of support and evaluation regarding the nominee's candidacy, with complete contact information (postal address, phone and e-mail address); and (2) the curriculum vita of the candidate being considered.

We are pleased to present the recipients of the Botanical Society of America MERIT AWARD

Dr. Michael Donoghue, BSA Merit Award 2014
Dr. Michael Donoghue
- 2014

Dr. Donoghue is a world-renowned botanist and a tireless champion of phylogenetics, evolution, and biodiversity research. He is an elected Fellow of the National Academy of Sciences (2005) and the American Academy of Arts and Sciences (2008), and most recently was awarded the prestigious Dahlgren Prize in Botany from the Royal Physiographic Society of Sweden (2011). Donoghue has consistently been ahead of his time—an intellectual leader in the development of new theory and approaches in systematics, species concepts, character evolution, historical biogeography, lineage diversification, and phylogenetic nomenclature. His ideas are always provocative; he has consistently rocked the boat, inspired debate, and moved all of us toward more rigorous thought.

His prodigious research career (he has published hundreds of papers) is matched by his inspired, continual service to our community, including many years in the Directorships of the Harvard University Herbaria and the Yale Peabody Museum. He has also trained and mentored dozens of students and post-doctoral associates, many of whom are now leaders themselves. All of his nomination letters make special note of how naturally Michael inspires his colleagues—and the botanical community at large—with his ideas and creativity, his enthusiasm, and his enormous generosity.

 


Dr. James Doyle, BSA Merit Award 2014
Dr. James Doyle
- 2014

Professor James A. (Jim) Doyle is recognized for his many distinguished contributions to paleobotany, particularly palynology, and to the understanding of angiosperm phylogeny.  Doyle and his associates demonstrated that, worldwide, the Cretaceous fossil record shows the primary adaptive radiation events of early angiosperm evolution.  One of his most valuable insights, derived from both cladistic analysis and stratigraphy, was the observation that angiosperms with tricolpate and tricolpate-derived pollen corresponded to a clade of angiosperms that included the vast majority of living flowering plants.  The existence of such a clade, the eudicots, has subsequently been strongly supported by molecular analyses and the concept has made its way into modern botany and biology textbooks.  Throughout his career and continuing into retirement, Prof. Doyle has shown himself to be an outstanding and inspiring teacher, at both the undergraduate and graduate level.  His lectures are meticulously organized, expertly delivered, and focused on principals yet packed with details.  His quirky sense of humor emerges and students are left amazed by how much they learned. Prof. Doyle trained nine graduate students over his career, and mentored innumerable other graduate students, postdocs, and faculty colleagues.  


Dr. Jeffrey Doyle, BSA Merit Award 2014
Dr. Jeff Doyle
- 2014

Dr. Jeffrey Doyle is an internationally recognized leader in the fields of theoretical and phylogenetic plant molecular systematics and molecular evolution. Over the past several decades he has consistently been at the forefront of the field of molecular plant systematics, contributing not only innovative methods, but also conceptual advances, as well as new empirical findings that have led to an improved understanding of plant diversity.  One letter writer notes that Dr. Doyle has  “an astonishing…record of insightful and sustained scientific achievement and has an immense impact on the direction of our field.” Dr. Doyle has made major contributions to clarifying evolutionary relationships among the legumes, the evolution of nodulation and also on the significance of polyploidy. Importantly, one letter writer notes that Dr. Doyle’s “commitment to undergraduate education is every bit as impressive as his research and scholarship.”  Jeff was not only an effective undergraduate teacher but also held a major administrative position at Cornell, Director of the Office of Undergraduate Biology. 


Dr. Charles Beck, BSA Merit Award 2013
Dr. Charles Beck
- 2013

Dr. Charles Beck is a distinguished paleontologist who has made remarkable discoveries in the history of land plants.  He discovered that the fern-like leaves of the genus Archaeopteris were in fact borne on a tree (Callixylon) with the anatomy of a gymnosperm.  This supported the viewpoint that seed plants were derived from free-sporing plants, and led to the identification of the progymnosperms, a group now included with gymnosperms and angiosperms in the larger clade, the lignophytes.   One of the people who nominated Dr. Beck for the award quoted Henry Andrews in saying that this discovery “blazed a rough trail through a dark forest where no recognizable path existed before.”  In addition, Dr. Beck is a skilled anatomist. After he “retired” from his position as Professor of Botany at the University of Michigan, he continued research.  In addition, he wrote a textbook, An introduction to plant structure and development, now in its second edition.  Dr. Beck has also served as Chair of his department, Director of the Museum of Paleontology, and as President of the International Organization of Paleobotany, and as Chair of the Paleobotanical Section of the BSA.  


Dr. Pat Herendeen, BSA Merit Award 2013
Dr. Pat Herendeen
- 2013
By linking paleontology and neontology, Dr. Patrick Herendeen, Co-Director of the Division of Plant Science and Conservation at the Chicago Botanic Garden, has made significant contributions to our understanding of the evolutionary history of the angiosperms, particularly the Leguminosae.  He has edited three symposium volumes on the family, in addition to producing a steady stream of careful publications on fossil and extant legumes.  In addition to his steady productive research, Dr. Herendeen has developed a truly remarkable career of service to the field of botany.  He has been chair of the Paleobotanical Section of BSA, Editor of the Bibliography of American Paleobotany, and chair of the BSA Publications Committee.  For four years he was Managing Editor of Systematic Botany, and another four years as Editor-in-Chief.  He took over the editorship at a time when the journal was facing considerable challenges; his efforts to steer the journal to calmer waters were largely behind the scenes but ultimately completely successful. Most recently he has become Editor-in-Chief of the International Journal of Plant Sciences.  In addition, he is in his second term as Program Chair for the ASPT and Systematics Section of BSA, a group that constitutes nearly half the attendees at the annual botany conference each year; thus Pat’s efforts are seen every summer in the success of the annual meeting.  As one of his nominators noted, “…there can be few active and well-respected plant scientists who have given as much service to the Botanical Society of America and to the broader botanical community…”
Dr. Lucinda McDade, BSA Merit Award 2013
Dr. Lucinda McDade
- 2013
Dr. Lucinda McDade is a scholar, teacher, and leader of scientific institutions.  She is currently Director of Research at the Rancho Santa Ana Botanic Garden, where she has also recently been appointed Executive Director of the Institution.  At RSA she also oversees the herbarium, a post that she previously held at the University of Arizona and at the Academy of Natural Sciences in Philadelphia.  At all three institutions, her energy and dedication were effective in modernization and development of the collections.  At the Academy of Natural Sciences, Dr. McDade was a major force in rehousing the herbarium, thereby securing the collections for generations to come. Dr .McDade has published on a wide range of topics but may be best known for her work on detecting hybridization in phylogenetic analysis, and for her career of studying the systematics of Acanthaceae.  Her research is noted for its care and rigor.  She has also had considerable impact as an educator.  For seven years, she was Scientific Coordinator for the Organization for Tropical Studies and as such coordinated the educational programs in Costa Rica.  In addition, she has taught extensively at the undergraduate and graduate level throughout her career.  In her nomination letter, however, the role that appears again and again is her skill as a mentor to all her colleagues and students.  She has provided encouragement and direction.  One former student noted that “[i]t is Lucinda’s generosity that I am left with …”  Finally, her service to the community has been extensive and varied, with too many contributions to list in this short space.   To quote again from the letter of nomination, “what sets Lucinda apart …. Is her sense of community, and her tireless labor on project that benefit the greater good.”
Dr. Patricia Gensel, BSA Merit Award 2012
Dr. Patricia Gensel
- 2012
Dr. Gensel, University of North Carolina, is an international leader in the investigation of early land plant evolution.  Her research, including rigorous field and laboratory work, has contributed significantly to our understanding of plant diversity at the time when major lineages of land plants were emerging. Through careful morphological and anatomical investigations she has brought “to life” extinct genera of early land plants and improved our understanding of the ecosystems in which these plants participated.  She is active as Professor of Botany at the University of North Carolina, where she has taught since 1975 and has encouraged and collaborated with many students and colleagues internationally.  Pat served as president of the Botanical Society of America in 2000-2001, during a time of great transition as the society began managing its annual Botany conferences independently of AIBS.

In her service to BSA, her role has been transformational for the Society and for the American Journal of Botany. Her influence on botanists through her research, instruction and service are incalculable. - University of California, Davis
Dr. Douglas E. Soltis and Dr. Pamela S. Soltis, BSA Merit Award 2010
Dr. Douglas E. Soltis & Dr. Pamela S. Soltis
- 2010
Drs. Douglas E. and Pamela S. Soltis are recognized for their far-reaching influence on many different sub-disciplines within the botanical sciences. Deeply involved with the field of molecular systematics since its infancy, they paved the way for such ambitious projects such as the National Science Foundation's Deep Time and Tree of Life projects contributing greatly to the understanding of floral evolutionary development, particularly in the basal angiosperms.

Their prodigious research productivity has not limited their service activities, however, as both Doug and Pam have served in leadership positions and as Presidents of BSA. Either would be outstanding in their own right, but together as frequent co-authors and collaborators, they continue to mentor and influence a generation of evolutionary scientists in resolving longstanding questions of angiosperm phylogeny.
Dr. Norm Ellstrand, BSA Merit Award 2009
Dr. Norm Ellstrand
- 2009
The Botanical Society of America recognizes Dr. Norman C. Ellstrand with the Merit Award for his studies on plant population genetics; Ellstrand is one of the country's foremost experts on plant gene flow, the movement of genes from one organism to another. His research has involved the study of the possibility of escape of genes from genetically engineered crops into their wild relatives as well as the potential consequences of that escape.

Ellstrand's work has shown that crops can mate with their wild relatives at rates and distances much higher than previously supposed. He also has shown that the hybrids are often more fit than suspected, suggesting that once transgenes occur in hybrids they will spread readily. Ellstrand has warned that if transgenes confer an advantage to a weed, such as herbicide resistance, that weed will become more difficult to control.

His recent research has come to focus on the evolution of invasiveness in plants. He was among the first to suggest that invasive species could evolve from relatively innocuous progenitors. Ellstrand is the author of more than 100 peer-reviewed research papers and of the influential book Dangerous Liaisons? When Cultivated Plants Mate with Their Wild Relatives. Norman Ellstrand is richly deserving of the Merit Award, the highest award of the Botanical Society of America.
Dr. Alan Graham, BSA Merit Award 2009
Dr. Alan Graham
- 2009
The Botanical Society of America recognizes Dr. Alan K. Graham with the Merit Award for his lifetime of perceptive and careful study, by which Graham has laid the foundations for our "concepts about the origins and history of tropical vegetation" in the Western Hemisphere during the past 75 million years. Encouraging numerous students and colleagues for several decades, he has greatly advanced the field of vegetation history, the basis of our understanding the past migrations of plants and animals in North and South America, their evolution, and the way in which we should understand their present distributions. For his life's works, the Botanical Society of America awards Dr. Alan Graham with its highest award.
   
Dr. Gar Rothwell, BSA Merit Award 2009
Dr. Gar Rothwell
- 2009
The Botanical Society of America recognizes Professor Gar W. Rothwell with the Merit Award because he has demonstrated a level of professional commitment and accomplishment that we all strive to attain. He is a world-class scholar as judged by his peers, an effective and persuasive teacher as judged by his University and students, and an active and convincing advocate for the plant sciences as judged by the scientific community. As noted by one of his peers: Rothwell's "work with fossil ferns of many types…helped to more accurately define the three major radiations of true ferns and to sharpen the focus when molecular clade estimates and phylogenetic analyses based only on molecular data conflicted with each other." These individual, but highly intertwined activities in his career have been carried out at the highest level of professionalism and with a sense of purpose that is rarely matched. "Scholar, teacher, and extraordinary professional citizen" for the plant sciences underlines the distinguished career of Gar W. Rothwell, who so richly deserves the BSA's Merit Award.
Dr. Marsh Sundberg, BSA Merit Award 2009
Dr. Marsh Sundberg
- 2009
Professor Marshall D. Sundberg has demonstrated excellence in basic research, education, and exceptional service to the professional botanical community. His studies on the morphology of teosinte and its relatives are considered stellar contributions. Sundberg has made many valuable contributions to the Society, especially to the teaching section (vice-chair, program chair and workshop and section chair for many years) and as chair of the committee which revised and expanded the valuable 1995 booklet, Careers in Botany. This small booklet with large outreach for our society and for educators provided the resources to help students and professionals alike to understand the importance of a botanical education and how they could apply it to their life's work. Professor Sundberg has also chaired the Society's Education Committee, Membership and Appraisal Committee and assumed editorial responsibility for the Plant Science Bulletin. As the current editor of our Bulletin, established in the 1950's as a vehicle for disseminating information for our colleagues in the Plant Sciences, Marsh has surpassed this goal with his choice of subject matter, editorial insights and innovative reports. Marshall Sundberg is a notable public ambassador, speaker, researcher and advocate for plant biology at state, national, and international venues. Marshall Sundberg has earned the Botanical Society of America Merit Award, the highest honor our society can bestow on a colleague who has made outstanding contributions to botanical science and dedicated his career to our profession.
Dr. Thomas Rost, BSA Merit Award 2008
Dr. Thomas Rost
- 2008
Dr. Thomas L. Rost is one of the world’s foremost researchers on root development. His research record spans four decades and includes more than 140 published papers in highly regarded journals, with 82 on root structure and development, plus 10 co-authored and co-edited books. These studies have laid down the foundations for understanding of root apical growth, especially involving cell cycle control and meristem function, lateral root production, root differentiation, epidermis and rootcap development, and root meristem structure in an evolutionary context. Tom’s papers have corrected the misconceptions about Arabidopsis that have dominated the previous 15 years of research on that model plant for developmental and molecular studies. He has led his students and post-doctoral researchers to a modern and accurate understanding of the development of this model root system. Specifically, he and his colleagues have shown that the architecture of the root apical meristem changes as the meristem ages. Also of particular importance, he has shown that the pattern of root apical meristem ontogeny is associated with periclinal divisions and gives rise to a three-dimensional arrangement of periclinal derivatives arranged in a helix.

Further, Tom has gone beyond Arabidopsis to put it in the context of root organization in angiosperms, especially dicotyledons, as a whole. Tom’s research on root apical meristems of a broad range of species (Azolla, pea, maize, cotton) have provided an important framework for understanding the streamlined structure of Arabidopsis roots. He has enabled his group to make unique contributions to understanding the structure and development of this genetic model organism. Tom Rost has done more than any other current structural botanist to bring the plant root to our attention as a dynamic developmental entity. However, his research has not been limited to roots. He has authored or co-authored impressive articles regarding seed structure and histochemistry, plant morphogenesis, and agriculture, and especially the recent studies on Pierce’s disease in grapevine. Further, Tom’s contributions to botanical education via his teaching/mentoring and his writings have been quite well known and recognized. With great pleasure, the Botanical Society of America is proud to recognize Dr. Thomas L. Rost with this highest award.
Dr. Warren Wagner, BSA Merit Award 2008
Dr. Warren Wagner
- 2008
The botanical community is indebted to Dr. Warren L. Wagner for his major contributions: monography of Oenothera, The Manual of the Flowering Plants of Hawaii, studies on speciation and relationships of Marquesan plants, and service at the National Museum of Natural History (Smithsonian Institution) are among those that will be most remembered. Born January 8, 1950 (Las Cruces, New Mexico), Warren early showed the enthusiasm for the New Mexico landscape. His work on Oenothera for his doctorate (1981) was at Washington University, St. Louis (Peter Raven, advisor). In 1982, he undertook what was probably one of the most difficult and at the same time, the most needed contribution in floristic botany: a flora of Hawaii. The previous flora (Hillebrand, 1888) was out of date, and subsequent contributions featured varied species concepts and were published in scattered places. The 1990 Manual (rev. 1999) was a major factor in permitting botanists to explore the amazing insular evolutionary phenomena that the Hawaiian flora contains. Wagner’s work on islands continued with the Marquesas, where cladistic studies and contributions using DNA permitted an understanding of the biogeographic nature of the remote and neglected archipelago. Wagner is both imaginative and practical, and has served as Chair of Botany at the Smithsonian, managed funds for IAPT and ASPT, and served in numerous capacities for professional societies. Moreover, his genial presence, encouragement, and knowledge have helped advance the careers of younger scientists. Thus, his identity in monographic, floristic, and phylogenetic botany has been multiplied significantly.
Dr. Bruce Baldwin
Dr. Bruce Baldwin
- 2007
Dr. Bruce Baldwin is recognized for his contributions in plant systematics. Beginning in graduate school, Dr. Baldwin studied one of the icons of island biogeography, the Hawaiian Silversword Alliance. His dissertation work using chloroplast DNA was one of the pioneers on island plant groups and confirmed that this morphologically diverse group represented a single colonization event from ancestors in North America. Baldwin reconfirmed these results using nuclear genes, the internal transcribed spacer (ITS) region. His development of ITS for plant phylogenetic study is perhaps his most widely recognized contribution. Less well-known outside of California is that Dr. Baldwin has made major contributions to plant floristics, through his efforts editing the Jepson Desert Manual and the 2nd edition of the Jepson Manual of California plants. For his many contributions to the systematics of Asteraceae, Hawaiian plant biogeography and evolution, and advances in molecular systematics, the BSA is pleased to recognize Dr. Bruce Baldwin with its highest award.
Dr. William Crepet
Dr. William Crepet
- 2007
Dr. William Crepet is recognized for his contributions in paleobotany, especially the reproductive structures of seed plants. Dr. Crepet's early work on interpreting the development of Cycadeoidea reproductive structure led to a better understanding of the enigmatic fossil group Bennettitales. However, for many, his most important contributions come from his ability to connect fossil and extant plants through phylogenetic study. This is especially true for his contributions to knowledge about fossil angiosperm floral structure, particularly ancient pollination syndromes and their role in flowering plant diversification. For his many contributions to paleobotany and plant phylogeny, the BSA takes pride in recognizing Dr. William Crepet with its highest award.
Dr. Edith Taylor
Dr. Edith Taylor
- 2007
Dr. Edith Taylor is recognized for her contributions in paleobotany. Her work has focused on the structure and evolution of fossil plants. Her detailed investigations have permitted the interpretation of functional and ecological aspects of plants, including phloem development, plant/insect interactions, and tree growth and adaptation to high latitudes. For over two decades she has brought to light the diversity of plants once living in present day Antarctica. The wealth of information from these studies has shed light on plant diversity at high latitudes in the southern hemisphere, plant biogeography and evolution, and climate history. For her many contributions to paleobotany, Antarctic paleoclimatology, and the biology and evolution of fossil plants, the BSA is delighted to recognize Dr. Edith Taylor with its highest award.
Dr. Ruth Stockey
Dr. Ruth Stockey
- 2006

Dr. Stockey has been a member of the Botanical Society of America for more than 30 years. She began her research career elucidating the structure and development of fossil conifers and is recognized as the world's expert in this area. Since moving to the University of Alberta, she has concentrated on anatomically preserved fossil angiosperms, providing data on floral structure, development, and phylogeny in these ancient plants. Her research has been supported by the Natural Sciences and Engineering Research Council (NSERC) of Canada for more than 26 years. Dr. Stockey is truly an "ambassador of botany" and is involved in collaborative work with colleagues around the world; her letters of support came from five countries! She is an enthusiastic teacher and her support and training of students is exceptional--one student began research in her laboratory in high school, and received her Ph.D. this year. For her many contributions to paleobotany, including her dedication to training the next generation of botanists, the BSA is proud to recognize Dr. Ruth A. Stockey with its highest award.
Dr. Barbara Webster
Dr. Barbara Webster
- 2006
Dr. Barbara Webster is recognized for her many contributions to plant development and structure. Her early work focused on abscission and senescence in higher plants, and included anatomy, ultrastructure, histochemistry, and physiology, as well as experimental work, especially on the genus Phaseolus. Beginning in the 1970s, Dr. Webster began to concentrate more on reproductive biology, but she has contributed to a wide range of topics, including nitrogen fixation in the legumes, environmental stress, and yield of crop plants. Her impressive publishing career spans more than five decades and includes more than 100 published papers and book chapters; her research has been supported by the National Science Foundation, the USDA and USAID. Dr. Webster was truly a pioneer in advocating for increased participation of women and minorities in science, and has served as a role model and mentor to both undergraduate and graduate students in plant biology. She is a fellow of the American Association for the Advancement of Science and the American Society for Horticultural Science, served as Treasurer and President of the Botanical Society of America, and has served as Associate Vice-Chancellor for Research at the University of California, Davis since 1989. As one letter writer noted, "It is hard to believe that Barbara has not already received this award." For her numerous contributions in many arenas to the field of botany, the BSA is proud to recognize Dr. Barbara D. Webster with its highest award.
Dr. Scott Russell
Dr. Scott D. Russell
- 2005
Dr. Scott Russell’s career has been devoted to understanding the morphological, physiological, and developmental aspects of double fertilization in plants, and in particular the structure and behavior of sperm cells during reproduction. Dr. Russell has explored this question using approaches ranging from descriptive works to experimental studies, resulting in over 100 scientific publications. His contributions have reshaped this field and have stimulated research in plant anatomy and morphology for a generation of botanists.

One of his most significant findings is that plant sperm from a single pollen grain are dimorphic, with dissimilar complements of organelles, and that this dimorphism leads to a predictable pattern of fertilization. His research has led to major advances in our understanding of key processes in sexual plant reproduction such as double fertilization and the maternal inheritance of organelles. Dr. Russell also continues to enhance public awareness of botany through his teaching and his informative website.

While the BSA Merit Award to Dr. Russell is based on his significant contributions to botanical science, he also has given generously of his time to the Botanical Society of America, serving as President, Webmaster, and longtime member of the Executive Committee, among other offices. Dr. Russell is most definitely a technically skilled, forward-thinking scholar who has made a lasting mark on botanical science and on the Botanical Society of America. In recognition of his myriad accomplishments, the BSA is proud to present him with a Merit Award.
Dr. Harry T. Horner
Harry (Jack) T. Horner
- 2004
Dr. Horner’s research has primarily focused on the cytology and development of anthers and pollen and on calcium oxalate crystal formation in plants. His research has been innovative, ground-breaking, and sustained. Over the past 43 years, he has published or has in press 110 papers in 43 high-quality refereed journals. His work is described by peers as “meticulous,” “pioneering and outstanding,” and “carefully documented.” His work calls on multiple tools and approaches, is often collaborative and interdisciplinary, and has earned him an international reputation as one of the most eminent specialists worldwide on plant ultrastructure. An indication of his stature as a researcher is invitations to three Gordon Conferences on calcium oxalate, for one of which he was chair and another vice-chair.

His “heroic service” and numerous contributions to BSA over many years are greatly appreciated. Through his participation on committees, as Chair of the Financial Advisory Board, and in elected office (two terms as Treasurer and President), he has been an agent of many positive changes in our Society. He has also served his department and Iowa State University as Director of the Bessey Microscopy Facility for 34 years, in administrative positions, and on numerous committees. He served as President of the Iowa Academy of Science. He has reviewed manuscripts for about 30 journals.

Along with this impressive research productivity and service, Dr. Horner has been a dedicated and effective teacher. He has taught three different courses on microscopy each for over 20 years and up to the present, and his teaching of microscopy techniques is renowned. He has successfully advised 13 M.S. students and eight Ph.D. students. Many of his students have gone on to highly successful careers, indications of the solid training and mentoring he gave them. He has served on well over 100 graduate student advisory committees in 21 different programs at ISU or elsewhere.

It is not surprising that his numerous accomplishments have brought him many awards, including a Special Award for long-standing continuous service to the Botanical Society of America, a Centennial Citation and Distinguished Service Award from the Iowa Academy of Science, and the highest award at ISU, a University Professorship.

One of the best measures of one’s reputation is recognition by peers. Hence from the supporters of Dr. Horner’s nomination we hear that he maintains “the highest standards of performance imaginable,” that he is a “model of clarity and rigorous scholarship,” as well as “an exemplary scholar and citizen–and a good guy.”
Dr. James L. Seago, Jr.
James L. Seago, Jr.
- 2004
This award is in recognition of the tremendous contributions Dr. Seago has made in encouraging and supporting students to pursue careers in botany. Dr.Seago has spent the majority of his career at the State University of New York, Oswego, a primarily undergraduate institution where the faculty carry heavy teaching responsibilities. Despite this, he has maintained an active research program involving undergraduate students and has mentored many of them to continue to graduate school in botany. It is primarily for his mentoring of undergraduates that we recommend Dr. Seago for this award.

If students do not enter botany, the field will wither away. Attracting students into botany may not advance one’s career as publications and grants do, but without a steady flow of new students, and especially students who are bright and interested, into botanical graduate programs, all botanists will have increasing difficulty publishing and obtaining funding. Dr. Seago has made remarkable and long-standing contributions to the flow of students into our discipline. He has the ability to spot interest and aptitude, to involve students in research, and thus to nurture their ability and interest. He has fostered student attendance at professional meetings and their presentation of papers at these meetings, and he has co-authored papers with students. In more than half of the past 30 years, Dr. Seago has coauthored a presentation or a paper with a student.

One colleague noted that “Jim obviously works closely with the students in planning the research and in helping prepare the talk, and the results are clear to all. Jim’s students know their stuff and are well prepared to present their work in the most professional and effective manner.” One colleague summarized Dr. Seago’s mentoring of students as an “unrivaled, significant, and persistent commitment toward fostering undergraduate botanical research over the last 30 years.”

Dr. Seago has encouraged many students to pursue careers in botany by actively promoting their applications to graduate schools. His matching of students with graduate programs that are right for them has not only benefitted the students but also the programs and ultimately plant sciences.

Dr. Seago has served his profession and his home institution in many important ways in addition to bringing students into botany. He was department chair for six years and has served on numerous committees at SUNY Oswego. He has served the Botanical Society of America as Program Director of the Developmental and Structural Section (1994-1997) and has been a diligent and hard-working reviewer for the American Journal of Botany.

Dr. Seago’s research deals with root developmental anatomy as well as the structure, development, and function of aquatic and wetlands plants. One colleague notes that “When one thinks of plants and roots, one must think of Jim Seago.” He has published 14 papers in refereed journals (nine papers in the American Journal of Botany) and has one in press. His research program, while modest in terms of number of publications and grant support, is admired by colleagues who describe it as “solid and substantial,” and “solid scholarly contributions.”

For his outstanding contributions to botanical science, and especially for being, as a colleague observed, the “vibrant, enthusiastic teacher and researcher” that he is, Jim Seago is unquestionably deserving of the Botanical Society of America’s highest honor.
Dr. Spencer Barrett
Spencer C.H. Barrett
- 2003
For his myriad contributions to reproductive biology, plant breeding systems and aquatic ecology. He established heterostyly as a model system in reproduction, contributed to understanding of the evolutionary modification of floral development, genetic structure of populations, the role of incompatibility in the breeding systems of natural populations, the evolution of dioecy and the influence of gender ratio in determining plant breeding systems.

Dr. Jack B. Fisher
Jack B. Fisher
- 2003
The 30 years of contributions made to botany by Dr. Fisher have been broad, deep, original, and patient. He has carefully combined anatomical, developmental, physiological, and ecological considerations, to show how tropical plants grow and adapt. He has made critical contributions to our understanding of water transport in lianas and fundamental discoveries on the developmental basis of tropical tree geometry. In the same way that he has waited patiently for tree seedlings to mature and yield their anatomical secrets, he has worked for 20 years to forge alliances between Fairchild Botanical Garden and institutions of higher learning to promote education of the next generation of comparative botanists. Dr. Fisher has benefited botany through his research and his thoughtful outreach and he richly deserves recognition through a BSA Merit Award for these admirable accomplishments.
Dr. Leslie Hickok
Leslie G. Hickok
- 2003
Dr. Hickok has made a career out of defying the odds and generating surprises. While others were intimidated by the high chromosome numbers of ferns, he showed that valuable insights into polyploidy and speciation could be obtained by studying their cytogenetics. While the mainstream focused attention on Arabidopsis as a plant model system, Hickok promoted the unique properties of the fern Ceratopteris. His pioneering work on selection and mutation using this model demonstrated the power of a system that separated gametophytic and sporophytic life stages. More recently, he has succeeded in marrying his deep commitment to advancing botanical knowledge and his desire to provide meaningful, enriching experiences for biology students. Through his insight and perseverance, he transformed Ceratopteris into C-fern, and now over 60,000 students per year are learning about plant genetics using this inexpensive but effective teaching system. Dr. Hickok is a distinguished scholar whose research and teaching efforts at all levels from K-12 to international seminars can be characterized as groundbreaking, inspirational, dedicated, and unselfish. For his outstanding contributions and longstanding generosity, the BSA is pleased to present a Merit Award to Dr. Leslie G. Hickok.

Jeffrey D. Palmer
- 2003
Dr. Palmer has excelled in his contributions to botanical science. His astonishing research productivity has resulted in over 200 scientific papers, many of them published in the most prestigious scientific journals. Dr. Palmer has fundamentally transformed the scientific landscape we now operate in through his legendary contributions to phylogenetics and gene and genome evolution. He has arguably been the most influential person in the development of the field of molecular systematics of plants and has been directly responsible for the paradigm shift in our current views of evolutionary relationships among eukaryotes, including higher plants. Other major contributions from his laboratory include the characterization and evolution of introns and plant mitochondrial genomes, the evolution of plastid genes in non-photosynthetic plants, and the origin and evolution of chloroplasts. The list of the graduate students and post-docs trained in his laboratory reads like a who's who of botanical science. His collaborative approach and willingness to share data has built a sense of community among plant molecular phylogenetics workers unparalleled in other fields of organismal biology. At the same time, Dr. Palmer has generously served as department chair at Indiana University as well as on review panels and editorial boards and has promoted outreach through his many public presentations. For his innovative and productive scientific contributions, Dr. Palmer has received many awards, among them the Wilhelmine Key Award from the American Genetic Association, election to the American Academy of Arts and Sciences and the U.S. National Academy of Sciences, and an ISI Highly Cited Award for the top 15 most cited plant and animal scientists. In honor of his extraordinary accomplishments, the BSA is proud to present him with a Merit Award.
Dr. Caroly Baskin







Dr. Jerry Baskin

Carol C. & Jerry M. Baskin
- 2001
We were impressed by their extensive contributions to the field of seed ecology, each having about 300 articles and other important publications. Their lab is the only one in the world that has been able to maintain a research focus on seed ecology for such a long time, since the mid-1960s.

The Baskins have also written a highly-praised book, "Seeds-Ecology, Biogeography, and Evolution of Dormancy and Germination, published in 1998 by Academic Press. An exerpt from one review of this book states " Carol and Jerry Baskin bring many years of seed germination experience with a wide array of species to what is an inspiring work. They interweave their own studies of numerous temperate North American species with those done by others world-wide. To provide some idea of scope, individual chapters contain hundreds of references, with two chapters each having more than a thousand. Just as the number of studies presented is extensive, so too is the number of species. Nearly 6400 are listed in the taxonomic index! These species provide a substantive base for the concluding discussion of biogeographic and evolutionary aspects of seed dormancy and germination. We are indebted to the Baskins' for their fine contribution, surely a labor of love, to the seed literature."

Proponents also cite Carol and Jerry Baskin's generous service to the Botanical Society of America and other societies, on editorial boards, and in helping undergraduate and graduate students. They have been an inspiration to their own students and colleagues worldwide as exceptionally kind and tolerant people.

Leslie Gottlieb
- 2000
Dr. Leslie Gottlieb has had a profound impact on the direction of plant systematics and has been one of the most influential plant evolutionary biologists over the past several decades. His 1977 paper in the Annals of the Missouri Botanical Garden, laid the foundation for the intelligent application of allozyme data in plant systematics. His 1982 paper in Science is a classic study of the duplication and conservation of isozyme loci in plants. His 1984 paper in the American Naturalist has been called one the most important papers in plant evolutionary biology during the past half century. However, his greatest contribution may have come through his influence on the careers and research of a substantial number of plant evolutionary biologists, including many of the people most active in this field today. Despite the fact that his research has often been more genetic or molecular in nature, Leslie has remained a botanist at heart.

Furthermore, she has trained 12 Ph.D. students, and hosted many postdoctoral and visiting scientists in her laboratory. Her service to professional societies is truly exceptional, including the presidency of BSA. As BSA President, she was a leader in the best sense of the word; she inspired others to contribute, and earned respect because she had a clear vision of her goals, and articulated them lucidly. She has also served as Executive Vice President of the Society for the Study of Evolution, on the Editorial Boards of three journals (Molecular Ecology, Functional Ecology, and Molecular Biology and Evolution), and on several NSF panels, while also serving as Chair of the Biology Department at Washington University, and most recently was elected to the National Academy of Sciences. Dr. Schaal is widely viewed as one of the most eminent of the Botanical Society of America, and has been the role model for many in the classroom and in her profession.

Tod Stuessy
- 1999
A productive and influential botanist with particular impact in plant systematics. His contributions include monographic studies in the Asteraceae, very early promotion of the burgeoning field of cladistics, strong advocacy for collections, and insights into the origin and evolution of island plants. He is a consummate internationalist, with huge influence in South America, Asia, and now Europe. His mastery of Spanish, and clear understanding and sensitivity for Latin American cultures, close ties with scientists, and various agencies has led to a multitude of collaborations and prodigious productivity—with over 200 publications including seven edited or single authored books. The highlight of the latter was his 1990 book, Plant Taxonomy: The Systematic Evaluation of Comparative Data, winner of the prestigious Henry Allan Gleason Award. He has trained 18 graduate students.
