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.
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.

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.
Dr. Walter Judd - 2012
Dr. Judd, University of Florida, Gainesville, is recognized worldwide for his contributions to plant systematics, taxonomy, and phylogenetics. Although he is very well known for his academic achievements, where he has focused on the systematics of the Ericaceae and Melastomataceae, as well as floristics in the southeastern United States and the West Indies, Dr. Judd is also an accomplished teacher, where at the University of Florida, he has been awarded numerous times for his excellence in pedagogy. He also has taught an internationally renowned class in tropical botany for the past 30 years at Fairchild Tropical Botanical Gardens and the Kampong in Miami. Dr. Judd is the lead author of the influential textbook, Plant Systematics: a phylogenetic approach, which has been adopted throughout the world as a model for teaching plant systematics and taxonomy. Dr. Judd’s passion for teaching, research, as well as learning, is ever influential to the graduate and undergraduate students he mentors. The 2012 BSA Merit award is a much-deserved honor for Dr. Judd.
Dr. Richard Olmstead - 2012
Dr Olmstead, University of Washington, is recognized for his outstanding contributions to reshaping the field of plant systematics, including his leadership on the use of chloroplast data in phylogenetic inference and angiosperm classification. His doctoral research with Melinda Denton resulted in a monograph of theScutellaria angustifolia complex (Lamiaceae). His subsequent research on Asteridae has resulted in major realignments in our understanding of family boundaries in Lamiales (especially Lamiaceae and Scrophulariaceae). He has published influential papers on a broad range of issues in systematics.
Dick has guided the careers of numerous undergraduates, graduates and post-doctoral fellows, fostered extensive collaborative research activities, and made significant service contributions to botanical and systematic societies. The integration of his excellent research program with public outreach activities through the Burke Museum and the University of Washington herbarium serve as a model for how we should be sharing our botanical knowledge to improve the world.
Dr. Allison Snow - 2012
Dr. Snow from The Ohio State University is recognized for her outstanding contributions to botanical science in the areas of basic research, education, and professional service. Allison's research on pollination biology, gene flow, and risk assessment of transgenic crops represent significant contributions to the field. She has mentored a number of students and researchers, and has been a strong advocate for communicating the importance of botany to the general public via the media. Finally, Allison has been deeply involved both nationally and internationally in service to a variety of organizations, including the National Academy of Sciences, the World Trade Organization, and as president for the Botanical Society of America.
Dr. Ann Hirsch - 2011
Dr. Hirsch, University of California, Los Angeles, is recognized for her outstanding contributions in the research of plant-microbe interactions, bridging the interactions among genes, plant growth regulators, signal transductions, and microbes. Her research is truly exceptional in combining field aspects of basic research and classical knowledge with molecular aspects, especially in legume-microbe interactions; she has been described as a bold and fearless experimentalist. Ann has also had a long and outstanding record in education where she has set very high standards, and her passion for research has created a stimulating laboratory environment for many undergraduate students, graduate students, post-docs, and visiting scholars to start or pursue careers in science. Dr. Hirsch has excelled in all aspects of her professional life and is richly deserving of the 2011 Merit Award.
Dr. Dennis Stevenson - 2010
Dr. Stevenson is recognized for distinguished contributions in the organization and phylogenetic relationships of cycads and cycad-like plants and is recognized for his breadth of publication which has included lycopods and ferns, bryophytes and gymnosperms, and monocots and dicots. Guiding the work of doctoral students and post-doctoral researchers, In the evolution of his own career, he has continued to set standards for studies of land plant anatomy and morphology, while increasingly serving as a strong public advocate for our discipline to the public.
His long and productive affiliation with the New York Botanical Garden has communicated the importance of fundamental studies of plants to the community at large.
Dr. Darleen De Mason - 2010
Dr. DeMason is recognized for her contributions in plant anatomy, which stress functional and structural aspects of stem thickening in monocotyledons, germination biology of palms, germination problems of the high sugar sweet corn genotypes, and leaf development in pea, elucidating auxin's integrating affect on developmental morphogenesis. A recognized scholar, teacher, academic leader and contributor to the botanical sciences, she has held various BSA posts, including Secretary of BSA and Council Representative and is noted for her volunteer work in improving the botanical environment of Riverside's Victoria Avenue Park. - University of California, Riverside
Dr. Nancy Dengler - 2010
Dr. Dengler is recognized for her significant scientific contributions in the areas of the developmental morphology of leaves, the evolution of plant anatomical patterns associated with C4 photosynthesis, and the role of the cell cycle and programmed cell death in plant developmental processes.
Generous as a scientist, colleague and mentor, Nancy is recognized as an excellent plant anatomist with extensive career achievements, including leadership roles as President of the BSA during a time of great transition for the Society. She has encouraged and inspired young botanists on both sides of the border and is among the most prominent of current plant biologists studying leaves. - University of Toronto
Dr. Judy Jernstedt - 2010
Dr. Judy Jernstedt is recognized for her careful scholarship providing new insights into morphogenesis and other aspects of development in myriad vascular plant systems. Examining such diverse systems as rhizophores, to contractile root development, to cotton fiber production, she has developed techniques to integrate the role of the cytoskeleton in biomechanical patterning of cell expansion and microfibril orientation in cell walls.
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 & 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 - 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.
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 - 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 - 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 - 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 - 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 - 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 - 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
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 - 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 - 2006
Dr. Ruth Stockey is recognized for her contributions to paleobotany,
especially to our understanding of the anatomy and development
of fossil conifers and angiosperms. 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 - 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 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
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.
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
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.”
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
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.
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. In addition to his service as Associate
Editor and Book Review Editor of the American Journal of Botany,
he mentored a generation of plant biologists, including 2
Master's students, 9 Ph.D. students and 6 postdoctoral associates
who have occupied faculty positions.
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.
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.
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
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.

Award for the best paper in the Phytochemical section in 1983.
He has been very active with the NSF, with the International
Organization of Plant Biosystematists, has provided frequent
service as a member of editorial and review bodies, and as
a cornerstone of the American Society of Plant Taxonomists.
He served the ASPT as President in 1988, and received their
most prestigious award, the Asa Gray Award, in 1997. His research
record is prodigious, with over 150 research articles. His
passionate dedication to botanical research marks him as one
of the leading systematic botanists/evolutionists of our time.
He made great contributions to understanding macroevolutionary
trends in plants and played a major role in the development
of molecular systematics, in particular with the publication
of the book, Plant Molecular Systematics. Through it all he
has kept his focus on the key scientific questions, not on
techniques. He has trained 19 graduate students. He exemplifies
impeccable scientific ethics while maintaining a genuinely
warm and considerate personality. He embodies the award criteria
