Both presentations also served to advance some of the salient concepts presented in the Myths about Botany Education Research Symposium. The annual subscription rate of $15 is included in the dues of the Botanical Society of America, Inc. Textbooks sometimes give Helmont the idea of the pot experiment to test whether plants have obtained their mass from the soil.
They also used the theory of the ancient Greek philosopher Thales (627-546 BC), who argued that all matter was formed from water (Krikorian and Steward, 1968; Walton, 1980). A cover would be effective in keeping leaves, twigs and other debris out of the pot. It may also have prevented larger animals from burrowing into the soil in the pot and prevented rain from splashing the soil out of the pot.
Helmont made no mention of the impossibility of completely separating soil and roots, which would have been a source of experimental error. The logical conclusion based on Helmont's published data would have been that very little of the plant's fresh weight came from the soil. These disputes resulted in a duel and his expulsion from the council of the Royal Society (Stanhill, 1986).
I brought pictures of the magnolia flower for the children and the email printouts of the information I received from Dr. Sundberg.
The Gleason Award
His astonishing research productivity has resulted in more than 200 scientific articles, many of which have been published in the most prestigious scientific journals. Palmer fundamentally transformed the scientific landscape in which we now operate through his legendary contributions to phylogenetics and gene and genome evolution. He has been perhaps the most influential person in the development of the field of plant molecular systematics and has been directly responsible for the paradigm shift in our current views on 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 graduate students and post-docs trained in his lab reads like a who's who of botanical science. 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.
Palmer has received numerous awards, including the Wilhelmine Key Award of the American Genetics Association, election to the American Academy of Arts and Sciences and the US National Academy of Sciences, and the ISI Highly Cited Award for the 15 Most Cited Plant and Animal Scientists. In honor of his outstanding achievements, the BSA is proud to present him with an Award of Merit.

THE IMPORTANCE OF HERBARIA
Orville Dahl 1910-2003
Orville Dahl received his doctorate in botanical cytology and genetics from the University of Minnesota in 1938. From Harvard, he returned to the University of Minnesota as a Professor where, for a decade, he was Chairman of the Department of Botany. Orville held a Professorship of Botany at the University of Pennsylvania, Philadelphia from 1967 to 1978 when he was appointed Professor Emeritus upon mandatory retirement.
He was one of the pioneers in the field of atmospheric pollen and spore studies and managed collection stations for over 30 years. His interest in pollen morphology, which began in earnest with work on the Icacinaceae, continued in many species throughout his life. The emphasis, especially in his teaching, was on living or well-preserved microspores and their development into pollen grains.
William Schopf, L.R.Wilson, influenced a generation of men and women who contributed greatly to studies of pollen and spore development, many aspects of archaeology, paleoecology, and hydrocarbon exploration. Orville spent many summers in the Stockholm area and took special pleasure in living in Vaxholm in the Stockholm Archipelago when possible and commuting to Stockholm by boat. Three of the grape varieties he planted have survived ten or more of our winters and now form an extensive arbor.
Orville was welcomed as a visiting researcher at Stockholm University, where we worked together in the Botany Department on many long-term projects. Shortly before his death, he spent a good Christmas in the company of his niece Karen, her husband Dr. The School of the Chicago Botanic Garden and the Garden's Institute for Plant Conservation Biology will present the Janet Meakin Poor 2003 symposium entitled "Sowing the Seeds for Change: Restoring Plant Communities" on Oct.
The restoration of plant communities makes an important contribution to the conservation of biodiversity. Should the restoration of a degraded nature reserve be treated differently than an area without native vegetation?

BULLARD FELLOWSHIPS IN FOREST RESEARCH
KATHERINE ESAU POSTDOCTORAL FELLOWSHIP
For example, the advantages of being small and living in the boundary layer are discussed in one of the chapters. Important factors in the distribution of cerrados include seasonal rainfall, poor soil fertility, drainage, fire regime and Quaternary climatic fluctuations. Nevertheless, given the human economy, time is probably short, and that is why this book was written.
We must congratulate the editors for the choice of the topics covered and the quality of the chapters. Concern about the environmental effects of invasive plants and animals dates back to the early history of the United States. The essays in the various chapters cover the field of the nature of exotic species in the Sonoran region and their effects.
Steven McLaughlin provides an interesting essay on the floristic composition of the Sonoran Desert with particular emphasis on the percentage of exotic plant species in the current flora. This book is documented with a glossary and appendices on relevant laws and checklists of exotic introduced plant and animal species in the Sonoran region. The review of Orchidaceae in chapter one tends to be redundant in light of the more specific discussions of Vanda Miss Joaquim in chapters 3-7.
The book 'Magnolia' discusses the value of the genus Magnolia in Chinese-Japanese herbal medicine. Most attention is paid to biphenolic compounds in the bark, such as magnolol and honokiol. Ilex opaca (American thistle) Polystichium acrostichoides (Christmas fern), both identified as native to the eastern United States.
However, the inclusion of these species obscures the book's interesting central theme: transplanted warm-climate plants. One of the pleasures of working in a discipline called economic botany is exploring the variety of subjects it covers. The impact of genetically modified food plants on the environment is discussed only in some case studies.
The third theme of the book deals with some concerns related to human consumption of genetically modified food crops. Despite the very interesting information in the table, no discussion was made, except to mention the subtropical origin of willow. Adanson there would have been no inquiries from the author and this book would not have been written.
A brief introduction to botanical terminology and vocabulary then leads to the glossary, which makes up most of the pages in Plant Names.
