EssentialBotanical Knowledge Symposium

Most potential future professional botanistsare now in our classrooms. How do . interesting and challenging? Also, how do we maintain the attention of those students who will not be botanists, but will be future voters? Do K-12 science and biology teachers understand botanical concepts? If not, how may this situation be remedied? Is there a concensus on what basic knowledge should be taught in an introductory botany course? Indeed, the very nature of this symposium raises numerous questions. If our discipline is to flourish and be properly understood and taught in pre-college classrooms, these questions need addressing by the botanical community as a whole. This symposium provides a vehicle for the presentation and exchange of ideas. This will be a continuing symposium dedicated to the eventual realization of a series of on-going position papers by the BSA on essential botanical knowledge that should be included in a college/university botany text, with a distillation therefrom for the purposes of transmitting key botanical concepts to grades K-12 in the public schools. Although the Teaching Section shall assume full responsibility for the output of the symposium, no position papers shall be published in the name of the BSA without approval by the Council and/or the pertinent sections of the society. Papers to be presented at the 1989 meetings are: "More, or More and Where Should We Start" (describing an innovative introductory course focused on photosynthesis), "Prolegomena to a Magic, Religion, and Science Chapter in a College/University Introductory Botany Text" (describing a novel approach to the teaching of the scientific method), "Botony, Taxons and the Sight of Photosynthesis" (describing basic botanical vocabulary skills), and "New Science Programs in Missouri" (describing the state-wide implementation of sequentially designed math and science exercises for grades K-12). All botanists are encouraged to attend and participate in the symposium, which is scheduled for Wednesday, 9 August from 8:00 a.m.-noon. Immediately following the symposium, a line luncheon-business meeting of the Teaching Section will provide further opportunities for the exchange of ideas with the symposium presenters and others. Please join us. For further information regarding the symposium and the procedures for becoming a presenter at future meetings, contact: Dr. Jeanette S. Mullins, The Lewis Herbarium, P.O. Box 653, California, PA 15419-0653 (412/938-2717).

Only Once a Year

Have you noticed that your botany students are becoming more and more "visual learners?" Does this present a problem in locating appropriate, professionally-presented visual classroom materials? The BSA has the "visual answers" to many of these problems. These "answers" are provided by the BSA Slide Exchange sponsored

2

by the Teaching Section. These excellent 2 X 2 color transparencies have been pre-pared by society members and are available at cost singly or in sets. This resource is available only once a year. These slides may be previewed and ordered at the BSA booth located in the AIBS exhibit hall. BSA members staffing the booth will assist you in previewing the slides and ordering procedures. For further information contact: Dr. Marshall D. Sundberg, Department of Botany, Louisiana State University, Baton Rouge, LA 70803.

Rewarding Experience

The rewards: meeting other botanists in a variety of disciplines, recruiting new BSA members, becoming involved with your society, and promoting botany generally. The experience: serving as a volunteer to staff the BSA booth in the AIBS exhibit hall during the Toronto meetings. This booth represents the society as a whole, as well as all of the sections. Therefore, this is an invitation to all BSA members to serve as

volunteer staff for the booth. Past and present society and section officers are encouraged to participate in this activity. Time slots of one-half hour each are now being scheduled as available. The booth will be open during the following hours: noon-7:00 p.m. Monday, 7 August and 9:00 a.m.-4:30 pm. Tuesday, 8 August and Wednesday, 9 August. All attending BSA members are encouraged to visit the booth and make any necessary corrections in their membership data. For further information and/or to sign up for a time slot, contact: Dr. Jeanette S. Mullins, The Lewis Herbarium, P.O. Box 653, California, PA 15419-0653 (412/938-2717).

A Note of Thanks

The logo of the Teaching Section, an illustration of Polygonatum biflorum, was made possible by the research of Charlotte Tancin of the Hunt Institute of Botanical Documentation and the permission of Dover Publications, Inc. The Section extends thanks and appreciation to both Ms. Tancin and Dover for their assistance.

BSA Ethics Committee: A Call for Members

An ad hoc Ethics Committee was established last year at the BSA Council meeting at The University of California, Davis. The roles of the committee are (1) to provide a forum for the discussion and resolution of professional ethical dilemmas faced by the Society's individual members, and (2) to offer recommendations to the Council concerning ethical matters facing the botanical profession at large. Among the first tasks to be taken up by the committee will be the development of a Code of Professional Ethics for the BSA. A number of other scientific societies in the U.S. have adopted such codes in recent years, and the goals of the BSA would be well-served by likewise formalizing some guidelines for professional conduct.

The BSA is already a member of the AAAS Professional Society Ethics Group, a consortium of more than 60 representatives of scientific societies in the U.S. The group publishes a quarterly newsletter, "Professional Ethics Report," which contains news, reviews, and commentary from scientists, philosophers, and ethicists across the country. With the formation of an ethics committee within the BSA, our Society can now enter into these highly important and timely discussions with a stronger and more focused voice.

BSA members interested in serving on our new Ethics Committee are invited to contact the current chairperson directly: Dr. Brian M. Boom, The New York Botanical Garden, Bronx, NY 10458.

Report from the National Council of Botany/ Plant Science Chairs

The Seventh Annual Meeting of the National Council of Botany/Plant Science Chairs was held at Purdue University last fall (October 29, 1988) and chaired by

3

Ronald C. Coolbaugh, Head of the Department of Botany and Plant Pathology at Purdue. In addition to 4 invited speakers, there were 26 participants representing institutions from all regions of the country. Participants were welcomed to Purdue by Robert L. Thompson (Dean of the College of Agriculture), who related some enrollment trends in his college that bear on the training of students in the plant sciences. The college has experienced an enrollment increase, but only about 1 in 10 students enters a career in production agriculture (farming) after graduation. Food Sciences is one of the most rapidly growing areas. He also commented that there is an inadequate number of students entering graduate programs in agriculture at Purdue; half of the current students are foreign born.

Hardy Eshbaugh (President of the BSA) gave a presentation entitled "Whence the Next Generation of Plant Scientists." (For the text of this speech, see Plant Science Bulletin of March 1989, Vol. 35, No. 1).

Carter Kimsey (Assoc. Director Metabolic Biology Program, National Science Foundation) reviewed "NSF Funding for Plant Science Research." Different sources of monies are available from NSF to support botanical research, but one of the major needs is for scientists to increase the flow of quality grant proposals to NSF. Plant scientists are also encouraged to contact NSF for new program information and especially to talk to directors of programs in which they might be interested in seeking funding. Submitting a grant proposal more than once (even more than twice) is not necessarily to one's discredit.

Judith Weis (Director, Biological Sciences Program, Undergraduate Science, Engineering, and Mathematics Education Division, NSF) spoke on the topic "NSF Funding for Plant Science Education." Although the absolute number of dollars for science education is relatively low, there has recently been a substantial increase in funding in this area. Analyses indicate that projects in the biological sciences receive a balanced share of the funding. Funding that has a direct bearing on plant sciences is likely to be appropriate, but as with other areas, accurate amounts are difficult to determine because projects involving plants may not be identified by their titles. In addition, major funding for programmatic needs in all botanical areas might obtain special funding if a community of plant scientists makes the needs known to NSF. Communicating such needs to the NSF might be a suitable joint project for several plant societies.

Orville Bentley (Asst. Secretary of Agriculture for Science Education, U.S.D.A.) gave a luncheon address entitled, "Biological Sciences: An Agriculture Perspective." He advised plant scientists at colleges and universities to take a leadership role in the development of curricula that stress basic biological principles, especially in introductory courses. Curricula might focus on such concepts as metabolic systems, biological-environmental systems (not environmental regulation) and biological technology. In addition, plant scientists must keep an active role in effective education of pre-college students.

The next meeting of the National Council of Botany/Plant Science Program Chairs will be announced. The meetings are open to representatives from any institutional departments or programs who are interested and concerned about enhancing plant science education and research.

Former LSU Professor Establishes Teaching Award

Dr. William J. Luke, a retired professor of botany at Louisiana State University, Baton Rouge, has donated funds to establish a cash award recognizing outstanding teaching by graduate students in the Department of Botany. The annual award will promote excellence in teaching and, because most of the graduate assistants are employed to teach undergraduate laboratory classes, the new award will also benefit undergraduate education at LSU. The first William J. Luke award will be given in the spring of 1990. Although teaching awards for graduate teaching assistants are available at the campus level, the W.J. Luke Award is the first such award within the Department of Botany.

Anyone who might be interested in using this manual (following the taxonomic scheme of Bold, Alexopoulos and Delevoryas and covering fungi, algae, cryptogams and phanerogams with 9 exercises on the anatomy of seed plants), please contact Dr. Perry at the Department of Biology, Frostburg State University, Frostburg, MD 21532-1099 (301/689-4166). He will send a table of contents and sample exercises to anyone who might be interested.

New Graduate Record Exam

The GRE Board is pleased to announce that the new GRE Biochemistry, Cell and Molecular Biology Test will be administered for the first time in October, 1990. The GRE Program will continue to offer the current broad-based GRE Biology Test. The new test is designed for use in the graduate admissions process and will reflect the undergraduate curricula of those departments that prepare students for graduate study in biochemistry, cell and molecular biology, microbiology, genetics, and other related fields. For further information on the new test, contact: Eldon Park, Graduate Record Examinations Program, Educational Testing Service, Princeton, NJ 08541 (609/734-5966).

Viable Seed of Drimys

Drimys grenadensis var. mexicana is an attractive shrub adapted to cultivation in a cool greenhouse. The genus is of special interest because of its evolutionary position and primitive flower and wood

structure. The plants bloom in early spring in the greenhouse. I have obtained fresh seed in 1989 from Costa Rica and a sample has germinated. Germination time in a mist chamber was about two months. Samples of seed are available on request from: Richard W. Pohl, Department of Botany, Iowa State University, Ames, IA 50011.

BOOK REVIEWS

Du Puy, David and Phillip Cribb. The Genus Cymbidium. Timber Press, Portland, OR, 1988. xix + 236 pp. ISBN 0-88192-119-X. Price: $59.95.

This is the definitive monograph of the orchid genus Cymbidium, an important group horticulturally, which has, surprisingly, never been treated before in a single volume. Some consider it the world's most popular orchid, and it certainly is commercially, with cultivation dating back to 500 B.C. in China. As I studied the text for my review, trying to think of a way to present a book of great appeal to orchid growers and hybridizers to such a diverse group as the present readers of the Plant Science Bulletin, I decided to evaluate its usefulness as a teaching tool for modern systematic botanists.

The advertising flier accurately describes the key features of this attractive book, which describes species widely distributed throughout southeast Asia: "introductory chapters cover structure and anatomy, chromosome numbers, pollination and floral fragrances, distribution and biogeography, and ethnobotanical uses. At the heart of the book is a complete taxonomic account of the 44 species recognized by the authors. The cultivation of Cymbidium is dealt with both historically and practically," providing very useful information. There is also an interesting chapter on the development of modern hybrids, a necessity when dealing with a group so involved with horticultural "improvement."

I think this is an excellent example of a botanical monograph with the following features: good keys to subgenera, sections, and species; general distribution maps; a variety of illustrations, including numerous line drawings of floral characters, outstanding watercolor paintings of the species, and high-quality color photographs showing close-ups and habitat shots; scanning electron micrographs of seeds and leaf surfaces; a very good example of the use of anatomical data to help make taxonomic decisions; charts for comparing characters of closely related species and subspecies; cladograms showing relationships between subgenera and sections; scatter diagrams and bar graphs superimposed on maps; examples of natural hybridization; comparisons of historical classification schemes; diagrams of analyses of floral fragrance compounds which have taxonomic value; complete synonymy for each taxon, including such categories as comb. et stat. nov., nom. rej., sect. nov., sp. nov., subsp. nov., and syn. nov. Although it is obvious that the authors, working at Kew, relied extensively on herbarium specimens for this study, there are no specimens cited except for types. There is a glossary and an index to names (not to subjects). My only objection is that the bibliography is listed by chapter, which means that some references are repeated several times; and you have to remember in which chapter a reference was mentioned in order to find it.

Overall, I was very favorably impressed by this well-produced volume; and even if you are not an orchid specialist, you would find it very useful as an example of a thorough modern monograph to be used for comparison purposes in teaching.

Wilms, H.J. and C.J. Keijzer, eds. Plant Sperm Cells as Tools for Biotechnology, Pudoc, Wageningen, 1988. 177 pp.

The apparent goal of this timely book is to summarize in one volume some of the new and exciting findings about the sperm cells of angiosperms and to highlight the potential of these cells in plant biotechnology. In this reviewer's opinion, that goal has been reached to a large extent.

After an introductory chapter identifying some of these recent findings, there are five chapters dealing with the development and structure of sperm cells. These are generally well-written. The last of these, an article by Emons et al. on aspects of plasma membrane structure in generative and vegetative cells of Lilium, is interesting and new but seems out of context in the present volume. The following five articles deal in various ways with what has been termed the "male germ unit" of angiosperms. Some of these rely heavily on serial ultrathin sectioning techniques and, although valuable in terms of further documentation of sperm similarity or dissimilarity within sperm pairs, they do not relate directly to the main thrust of this book. The sperm cell isolation section contains four articles dealing with many of the intricacies of harvesting live sperm cells for fusion, physiological, or other studies. These articles serve as reminders of the difficulties which surround this potentially productive exercise. Of particular relevance in this regard is the article by Kerhoas and Dumas in which the important issue of pollen quality is discussed. Finally, there are three articles on the relationship between sperm cells and plant breeding. The article by Barnabas and Kovacs contains some interesting information on freezing of pollen; the implications of such technology to the freezing of isolated sperm cells are considerable. In my opinion, this is a high priority topic for this field.

There are a few things which detract from the quality of this book. One of these is the inclusion of many illustrations at the end of the book (pp. 153-177) rather than being integrated with the articles themselves. I understand the technical difficulties of doing this. There are some minor mistakes and redundancies in various parts of the book. In my opinion, these do not create big problems for the reader but could have been weeded out with more careful editing.

This reviewer is pleased to see such a book. It will call attention to a unique cell type in the angiosperms which opens up many avenues of research, including membrane biology, in a plant cell which can be readily obtained as a "natural protoplast."

Its impact on the plant cell and molecular wealth of new information and ideas and is biology community should be considerable. relatively easy to read. It allows neophytes to acquire a comprehensive.

Beck, Charles B., ed. Origin and Evolution of Gymnosperms. Columbia University Press, New York, 1988. 504 pp. Price: $65.00.

The origin and evolution of the gymnosperms is one of the most highly debated subjects in paleobotany at the moment. The book edited by C.B. Beck includes 10 chapters written by international experts on the history of this group. It treats the major fossil and living families, which are presently known, in chronological order. The part devoted to taxa from Gondwana and Angara by some authors is appreciable and noteworthy.

Nowadays, an outstanding fact in the systematics of gymnosperms is the rapid increase of data available for these plants. One of the qualities of this book is to provide in every chapter a clear and up-to-date synthesis of the available information. The systematics of gymnosperms is also marked by the use of more and more rigorous methods for the analysis and treatment of the data. One of the most discussed techniques is the cladistic method, which bases relationships between taxa upon shared derived characters. This method inspired Beck and Wight in the chapter on progymnosperms, Crane in his analysis of the "higher" gymnosperms (excluding conifers), and Miller in his presentation on the origin of modern conifer families.

The paper written by the late Sergei V. Meyen--to whom this book is dedicated--represents a synthesis of the phenomenal work he accomplished in more than twenty years of research on the Paleozoic taxa from Angara. In this book, Meyen analyzes these remains according to his original method of "assemblage taxa." His interpretation of the "Pinales" is particularly interesting to compare with that, somewhat different, of the "Conifers" expressed by Clement-Westerhof in a preceding chapter.

For Scheckler and Rothwell, gymnospermous reproduction in the earliest representatives of the group is characterized by a "hydrasperman" biology, which involves the nucellar apex in pollination and post-pollination mechanisms. The biological and morphological characters by which gymnospermous reproduction would be established in the male reproductive structures remain to be studied. This problem is briefly mentioned by these authors and by Galtier in the following chapter. In addition, Taylor presents a detailed review of the pollen and pollen organs of well-established gymnospermous affinities. He is the only author who discusses the pteridosperms of Upper Carboniferous age, a complex of taxa some-what forbidden in this book.

Finally, Galtier's contribution on the early Pteridospermales needs to be emphasized, as it is an original work which provides new information on some morphological and anatomical characters of these plants. Based on these data, which are displayed in a series of eloquent tables and diagrams, Galtier suggests some interesting hypotheses relative to the phylogeny of these early gymnosperms.

In conclusion, this book presents a wealth of new information and ideas and is a relatively easy read. It alows neophytes to aquire a comprehensive knowledge and a good understanding of the gymnosperms. For experts, it gives numerous prospects for future projects involving these plants.

Brush, Stephen G. The History of Modern Science: A Guide to the Second Scientific Revolution, 1800-1950. Iowa State Univ.
Press, 2121 S. State Ave., Ames, IA 50010. 1988. xv + 544 pp. Price: $39.95 + $2.00 postage and 4% sales tax in Iowa.

Here is a guide and introduction to the history of modern science by a distinguished historian of science. It gives very basic information and many references to books and journal articles where further information can be found. The first chapter considers the general changes in science during the period that the author calls the "second scientific revolution." There also is given references for background on the sciences during the previous three centuries. The next three chapters concern biological issues related to evolution and genetics. After that there are two chapters on psychology. Except for the chapter on the philosophical and social aspects of science, the other chapters are on the physical sciences: chemistry, physics, and astronomy. Each chapter has a number of sections. For example, the evolution chapter has these sections: history of the Earth; life sciences before Darwin; origin and early development of Darwin's theory; reception of The Origin of Species; and human evolution. Each section has a listed set of basic readings, a synopsis of the major issues, and a bibliography divided into particular topics. The topics listed in the section "Life sciences before Darwin" are: 1) reproduction and heredity, 2) taxonomy and fossils; Buffon, 3) theology, 4) nature philosophy, 5) Lamarck, 6) cell theory, and 7) organism as machine.

The books referenced in the text are listed in an appendix, with prices when they are now in print, and they are keyed to the various sections in which they have been cited. A brief page and a half index leads to some of the major themes that are considered.

This is not a book that most people would sit down and read from cover to cover unless they wanted to do a self-study in the history of science. It is a source book for someone wishing to locate authoritative and contemporary information about some aspects of the history of science. It would be useful for teachers wanting to add some historical background to their courses, or for assignment to students to enlarge their perspectives. It is unfortunate that the index is so sparse; a detailed one would have been more useful for the casual user. This reference book should be available to you in your school or public library, if not in your own.
