ACTIONS OF THE COUNCIL AND BUSINESS MEETING

The Council of the Society met on August 17. 1975 and the business meeting was held on August 19, 1975 at Oregon State University, Corvallis in conjunction with the AIBS meeting. A synthesis of the various decisions of Council and of the membership is given below:

The following officers were elected: PRESIDENT (1976)-Barbara F. Palser; VICE-PRESIDENT (1976)-William A. Jensen; PROGRAM DIRECTOR (1976-1978)-Shirley C. Tucker; EDITORIAL BOARD, A.J.B. (1976-1978)-Donald R. Kaplan. The SECRETARY, Patricia Holmgren, and the TREASURER, C. Ritchie Bell. continue in office through 1976.

The "Guide to Graduate Study in Botany," revised by W. W. Payne of the Education Committee, is available and over 400 copies have been sold. The Career Booklet continues to have wide distribution with over 5,000 copies distributed since the last annual meeting. The 1973-1975 Yearbook was distributed to all members of the Society in the fall of 1974.

In the Treasurer's report, it was noted that membership decreased from 4,423 in June 1974 to 3.222 in June. 1975 and that there was a net loss of $25,000 for the year ending in June 1975. Thanks to an increase in dues and a reimbursement of the Society by the Journal for hack taxes, a net gain of $4,000 is projected for 1975. the first surplus in several years. The hope is to build a reserve of $65,000, i.e., a one year operating expenses. Full financial details were provided the Council and the membership by Dr. Bell, the Treasurer.

Dr. Richard A. Popham, Business Manager of AJB, presented a detailed written report on the financial status of the Journal. There was a net increase in 1974 of $25,000 to be used to build up a one year reserve and to increase the number of pages printed in an effort to reduce the back-log of manuscripts.

Dr. Ernest M. Gifford, Editor of the American Journal of Botany, reported that the acceptance rate of manuscripts is about 80% and the average time interval between receipt and publication is 11-12 months.

Dr. Augustus E. DeMaggio discussed the activities of the Program Chairman, noting cost-saving moves introduced for publication of abstracts.

Reports of Sections and Committees were inserted into the minutes of the Society and various awards were announced.

MERIT AWARD

This award is made to persons judged to have made outstanding contributions to botanical science. The first were made in 1956 at the 50th anniversary of the Botanical Society and one or more has been presented each year since that time. This year the Award Committee has selected three botanists who are eminently qualified to join the ranks of merit awardees.

Harlan P. Banks of Cornell University for his distinguished teaching of undergraduate and graduate students, numerous contributions to our knowledge of early land vegetation and services as a former President of the Botanical Society of America."

F. Herbert Bormann of Yale University "for his distinguished studies of nutrient and water flow through the Hubbard Brook Watershed, for his numerous important pronouncements on environmental hazards and for his responsible actions on behalf of the biological community."

William Campbell Steere of the New York Botanical Garden "for his fundamental contributions in the biology of the bryophytes and Arctic botany, and a long-term successful development in the administration of the New York Botanical Garden."

DARBAKER AWARD

This award is made for meritorious work in the study of microscopical algae. The two recipients are selected by a Committee of the Botanical Society which bases its judgement primarily on papers published during the last two full calendar years.

Sarah P. Gibbs of McGill University "for her significant contributions to our understanding of the Chrysophycean alga Ochromonas danica, including the fine structure of nuclear and cell division. She has concentrated on the autonomy and replication of mitochondria and chloroplasts, providing prima facie evidence that the DNA content of the chloroplast increases during development, with this development being regulated by chloroplast DNA as well as that of the nucleus."

Larry R. Hoffman of the University of Illinois "for his account of fertilization in the Chlorophycean alga Oedogonium, spanning plasmogamy, polyspermy and karyogamy. He has provided perhaps the most complete description of karyogamy in any alga to date. greatly adding to our information concerning this significant event in plants in general."

JEANETTE SIRON PELTON AWARD

The Jeanette Siron Pelton Award for sustained and imaginative productivity in the field of experimental plant morphology was established in 1969 by the Conservation and Research Foundation to honor the memory of the late Mrs. John F. Pelton. The Award consists of $1,000 given from time to time to a scientist nominated by the Botanical Society of America.

The fourth recipient of this Award is Dr. Peter Klock Hepler, whose penetrating analytical and experimental studies of the ultrastructure of differentiating cells have made a significant and lasting contribution to our perception of morphogenesis at the cellular level. In particular his work on the ultrastructure of differentiating xylem elements, on the roles of microtubules and microfibrils, and on the control of the orientation of mitotic spindles in differentiating cells have provided new insights which hold great promise for the future.

NEW YORK BOTANICAL GARDEN AWARD

The New York Botanical Garden presents an award to the author of a recent publication making an outstanding

3

contribution to the fundamental aspects of botany. The recipient is selected by a committee of the Botanical Society.

Sol Bartnicki-Garcia of the University of California, River-side "for demonstrating that chitin cell wall microfibrils can be synthesized in vitro without a template and also for other past studies of fungal morphogenesis."

HENRY ALLAN GLEASON AWARD

The Henry Allan Gleason award of The New York Botanical Garden is made annually for an outstanding recent publication in the field of plant taxonomy, plant ecology, or plant geography.

This year the award is made to Dr. Daniel Janzen, an ecologist in the true sense, who considers whole ecosytems, not just plants or just animals. The paper is "Tropical agroecosystems," published in the issue of SCIENCE for December 21, 1973.

JESSE M. GREENMAN AWARD

The Jesse M. Greenman Award is presented each year by the Alumni Association of the Missouri Botanical Garden. It recognizes the best paper in plant systematics based on a doctoral dissertation published during the previous year.

The 8th annual award, in 1975, goes to Dr. James E. Rodman, Yale University Herbarium, Osborn Memorial Laboratory, New Haven, Connecticut for his paper "Systematics and Evolution of the Genus Cakile (Cruciferae)."

PALEOBOTANICAL SECTION AWARD

Annually an award is made to the author of the most outstanding paper presented at the annual meeting of the Paleobotanical Section of the Botanical Society of America.

This year's award is to Charles Daghlian, University of Texas, for his paper entitled "Leaf remains of Philodendron."

GEORGE R. COOLEY AWARD

The George R. Cooley Award is given annually by the American Society of Plant Taxonomists for the best paper presented at the annual meetings.

This year the Award is presented to William R. Anderson, University of Michigan, for his paper entitled "The nature and significance of cleistogamy in the Malpighiaceae."


Dr. Anitra Thorhaug presented the final report of the Charter Flight Committee for Dr. Joseph Arditti. A "profit" of $2,120.06 was recorded. This money was placed in the Dimond Award Fund for the next International Botanical Congress. The Council unanimously voted to thank the Committee for their efforts as did the membership at the Business meeting.

Dr. Harlan Banks, chairman of the Cookson Fund Committee, noted a gift of $3,000 from Isabel M. Cookson to establish a Paleobotanical Award for the best contributed paper in paleobotany presented at the annual meeting of the Society.

The Committee on Scholarly Communication with the People's Republic of China requested that the Botanical Society join them in their efforts. President Peter Raven appointed a committee, chaired by Dr. Arthur Galston, to develop a coordinated response for the Botanical Society.

THE CACTUS FIELD BOOKS OF DAVID GRIFFITHS. For preparation of The Cacti of the United States and Canada (in press, Stanford University Press), I am curating the David Griffiths' collection of cactus specimens, mostly prickly pears. These were prepared at the U.S. Department of Agriculture during the Burbank cactus boom and bust at the turn of the century. The collection passed to the Smithsonian Institution and for many years was stored at the U.S. National Herbarium. In 1956, I was invited to curate the collection, the original set to be deposited in the National Herbarium and the first set of duplicates in the Herbarium of Pomona College. The original specimens were returned to the Smithsonian in 1970 and those from Mexico are still under study.

Griffiths' specimens are good ones, but many have no labels because the field books have not been found. Griffiths kept meticulous records; the book covering earlier studies at the University of Arizona gives complete field records of all collected specimens. The question is, "What has happened to the later field books?" The labelling of perhaps half the thousands of specimens is impossible with-out further data.

Data for many of the collections have been obtained by hook or crook. Garden record books found at the Smithsonian provided at least place names for some labels, and some data were supplied from the accession cards of the Plant Introduction Garden at Chico. California. But there is still a large residue of specimens well pressed and ready for mounting with no information except field numbers. In view of the back-breaking work necessary to obtain and press thousands of cacti, the value of salvaging these potentially valuable specimens can be appreciated. Several obvious possible sources have failed to uncover the note-books. Dr. Griffiths' secretary during the period of cactus investigation, his family and various institutions in Washington have not been able to locate the field books. I appeal to anyone who may he able to supply information concerning the Griffiths' field books. Any help will be appreciated by Pomona College where the unlabelled specimens occupy several herbarium cabinets, by the Smithsonian Institution and by all interested in the study of Opuntia. Please contact Lyman Benson, Department of Botany, Pomona College, Claremont, Calif. 91711.

BOTANICAL POTPOURRI

JEFFERSONIA is a newsletter devoted to all aspects of Virginia botany. We welcome all articles dealing with history, biography, and bibliography as well as scientific papers concerning botany in Virginia.

The newsletter is published quarterly by the University of Richmond and subscriptions are $2.00 per year. Manuscripts and requests for information should be sent to: Howard M. Smith, Editor, Department of Biology, University of Richmond, Virginia 23173.

The American Society of Plant Taxonomists announces the formation of a new journal, SYSTEMATIC BOTANY, which will begin publication in 1976. It is intended that a minimum of 400 pages per yearly volume will be published, the issues to appear quarterly. The editor will be Dr. William Louis Culberson, Department of Botany, Duke University, Durham, N.C. 27706. Membership in the ASPT is welcomed from all persons interested in biological systematics, reproductive and evolutionary biology, biogeography, chemotaxonomy, numerical taxonomy, or paleontology.

A limited number of the following monographic issues of the Journal of the Elisha Mitchell Scientific Society are available at $5.00 per copy: W. C. Coker, The Lactarias of North Carolina; W. C. Coker, The Amanitas of the Eastern United States; and H. C. Beardslee, The Russulas of North Carolina. Copies of the volume entitled Mycological Studies Honoring J. N. Couch are available at $10.00 each. Make check payable to the Elisha Mitchell Scientific Society. Address all orders to the Executive Editor, Department of Botany, University of North Carolina, Chapel Hill, N.C. 27514.

The GUIDE TO GRADUATE STUDY IN BOTANY FOR THE UNITED STATES AND CANADA, 1974, published by the Society, lists 98 plant science departments in the U.S. and 20 in Canada which offer the Ph.D. Each departmental listing includes the name and address of the institution, name of department with number of faculty, current graduate enrollment, fields of specialization and titles of recent Ph.D. theses. The GUIDE is invaluable in assisting students in making choices of graduate schools. It is available at $3 from Dr. Patricia Holmgren, Secretary, Botanical Society of America, The New York Botanical Garden, Bronx, N.Y. 10458. Checks should be made pay-able to The Botanical Society of America, Inc. and should he included with the order.

Advice to Beginning Graduate Students

1. DO introduce yourself to departmental office personnel, and then get out of the office.

DON'T hang around the office. It's full of cranky old women who are out to get you or with pretty young women—ditto.

2. DO stay within the confines of your assigned hole which is in keeping with your station in life.

DON'T put your bottom in the chief's chair and day-dream of occupying it.

3. DO write or type your own letters.

DON'T think that secretaries have been put on earth for the pleasure and convenience of graduate students.

4. DO accept only those departmental keys which are necessary to sustain life, i.e., access to your hole, laboratory and building.

DON'T acquire, borrow, find or duplicate any other keys. Eventually some fugitive from the CIA will find out about it and then all the locks will be changed with consequent paranoia all around.

5. DO run your own errands and offer to pick up whatever the "girls" want. You're young and the exercise will do you good.

DON'T bother me — I can't cope.

6. DO offer to fill teaching emergencies. Faculty may not even thank you . . . but they remember.

DON'T think that your time is as valuable as that of a professor. It really may be, but you won't find anyone beside yourself who will agree with you.

PERSONALIA

Following the appointment of Professor J. E. Cruise to the Directorship of the Royal Ontario Museum, Dr. John Grear has been appointed to the position of Curator of the Vascular Plant Herbarium of the University of Toronto (TRT) .

Peter H. Raven, director of the Missouri Botanical Garden and professor of biology at Washington University, has been named George Engelmann Professor of Botany. With this appointment, he becomes the fourth botanist to be so honored since the Engelmann chair was established at Washington University in 1885. Previous Engelmann professors, all of whom were or became directors of the Missouri Botanical Garden, and their periods of tenure as Engelmann Professor include: William Trelease (1885-1909) ; George T. Moore (1909-1937) ; and Edgar Anderson (1937-1966).

Engelmann, a former WU professor, physician, botanist and meteorologist, was the man who served as advisor to

Henry Shaw when he set about to create what is now known as "Shaw's Garden." As Shaw's emissary in 1857, Engelmann purchased the Bernhardi herbarium in Erfurth, Germany, a 40,000-species collection which formed the nucleus of the present-day herbarium at the Missouri Botanical Garden, one of the most important in the world. Through the efforts of these iwo men, the Missouri Botanical Garden was founded in 1859.

University of Texas System Regents approved the appointment of Dr. Harold C. Bold, UT-Austin professor of botany, as the first C. L. Lundell Professor of Systematic Botany. The Lundell Professorship of Systematic Botany was established by a gift to the University by Dr. and Mrs. C. L. Lundell in 1972. Among the many professional and academic organizations in which Dr. Bold is active are the Botanical Society of America, Phycological Society of America, the Southwestern Association of Naturalists and the Texas Academy of Science. He is a member of the National Academy of Sciences and a Fellow of the American Academy of Arts and Sciences.

On September 20, 1975 Dr. Scott Mori began a two year appointment as a research associate at The New York Botanical Garden. Dr. Mori is working with Dr. Ghillean Prance on a monograph of the New World Lecythidaceae for eventual publication in Flora Neotropica. Volume I will include treatments of Asteranthos, Gustavia, Grias, Allantoma, and Cariniana and is scheduled to he completed by September 1977.

ACTIVITIES OF THE SECTIONS

News of the Developmental Section

In connection with the meeting at Oregon State University in August 1975, the Developmental Section held a luncheon meeting. The great minds elected the following officers: Chairperson: Howard Bonnett (Dept. of Biology, Univ. of Oregon, Eugene 97403) ; Vice-Chairperson: Peter Kaufman (Dept. of Botany, Univ. of Michigan, Ann Arbor 48194): Representative to the American Journal of Botany: William Millington (Dept. of Biology, Marquette University, Milwaukee, Wis. 53233): and Secretary-Treasurer: Barbara Webster (Dept. of Agronomy and Range Science, Univ. of California, Davis, Calif. 95616, AC 916-752-2468).

It was decided that abstracts submitted to annual meetings of the Society to the Developmental and to the Structural Sections should be integrated in order to achieve a more coordinated program. Accordingly, Don Kaplan (Secretary to the Structural Section) and I have worked together to schedule presentations for the forthcoming meetings at Tulane. We received a total of 78 abstracts.

Members of the Development Section raised the question of NSF funding within the Developmental Biology Program at the annual meeting in Corvallis. I am passing along the data sent me for fiscal year 1975. Forty of 104 (38.5%) proposals with a botanical orientation were funded compared to 76 of 197 (38.6%) proposals with a zoological orientation. This included proposals for small supplements, conferences, etc., as well as competitive re-search proposals. It excluded proposals for work with Dictyostelium, Physarum, bacterial sporulation, etc. On the basis of these data, botanists appear to be competing equally for grant support.

11

There are 2 vacancies for Corresponding Members of the Botanical Society. According to the by-laws of the society, "Corresponding Members shall be chosen from authors of important contributions to the science of botany." The Developmental Section does not have a defined procedure for the nomination of persons for corresponding membership, but the following guidelines are suggested: 1) any member interested in the nomination of a person for corresponding membership should send name and vitae of the nominee to Howard Bonnett, requesting sponsorship of the Developmental Section for the candidate; 2) the member should then send bibliographic information, including a list of publications of the nominee, to members of the Developmental and other Sections, requesting their support in the form of a letter of recommendation. Sup-porting letters on prospective Corresponding Members should be sent to Dr. Peter Raven, Chairman, Committee on Corresponding Members, Missouri Botanical Garden, 2315 Tower Grove Ave., St. Louis, Mo. 63110. I think you will be pleased to know that Dr. Elizabeth Cutter, a member of the Developmental Section, was elected as a Corresponding Member by the Society at its 1975 meeting.

BOOK REVIEWS

AITKEN, YVONNE. Flowering Time, Climate and Genotype. Melbourne Univ. Press. 1975. 193 pp. $29.70.

The book by Yvonne Aitken represents an excellent report of her research program on flowering of several agricultural plants over a wide range of geographical latitudes and climates. The plants for which development and flowering seasonality were mainly investigated were: wheat, peas, subterranean clover, red clover, oats, ryegrass, and barley; all from two important families: grasses and legumes. Auxiliary information is provided for 45 more species. The generalizing title of the book is further justified by the introductory 20 pages of history of phenology and plant development and climate. The chapters following carry similarly generalized titles but cover basically the subject platter with regards to the crop plants mentioned: Plant development and shoot structure (20 pp.), climate and growing season (42 pp.), maturity genotypes (various aspects and chapters, 86 pp.), and application of develop-mental analysis (26 pp.).

Ms. Aitken studies especially the maturity genotype concept under different climatic constraints like growing season length. temperature, photoperiod. The discussions demonstrate the enormous amount of field work that has gone into this book. It is impossible here to cover the many aspects of seasonal development that were investigated. The book is a bonanza for modelers searching for excellent data. Fifty-four figures, many with several individual blocks, excellently drawn, illustrate the data gathered. Numerous tables back up the statements contained in the text. This explains the price of almost $30 for a book of 193 pages.

The book is a substantial contribution to plant development and seasonality research. It should certainly be respected by all agricultural climatologists and crop ecologists. The many examples presented invite the use of the book as reading material in developmental biology. Text-book writers should consult this book for its excellent graphs to demonstrate evidences for seasonality, temperature vs. photoperiod effects. etc. The authoress should he highly commended for this major contribution to phenology.

The vascular plants of a coastal area approximately 150 km long by 100 km wide, centered around the city of Corpus Christi, are treated. Included are 1,321 species in 585 genera in 135 families. Clear and concise dichotomous keys and short descriptions and distributional statements are given. Topography, climate and vegetation are summarized briefly. One new species, Boerhavia rrrathisiana Jones. is described in Latin and English. A few very well done line drawings by Evelinc Jackson are presented.

This is a superb local flora of the kind one wishes were available for every region. Mr. Jones is to be warmly congratulated.

1975. 398 pp.

This volume contains papers presented at a 1973 symposium in Caracas. All 25 papers are in English and the 42 contributors represent 11 countries; more than half the contributors are from temperate latitudes. The book is divided into eight sections, each section preceded by a brief and almost information-free introduction by the editors. The papers are of much more uneven quality than one would normally expect to find in a volume of this sort. They include literature reviews, premature data papers, and, happily, six or eight papers which are outstanding examples of high quality tropical ecological research.

Almost half of the titles are of interest to tropical ecologists whose interests are primarily botanical. Hart-shorn gives a lucid review of his application of l.efkavitch's population model to Pentaclethra macroloba, an important tree in the wet Atlantic lowlands of Costa Rica. Knight examined various ages of second-growth on Barro Colorado Island, Panama, and adds to the scant literature on succession in tropical American forests. In a monograph-length paper. Montgomery and Sunquist report their studies dealing with sloths, including their feeding behavior and impact on the forests. Haines provides new data on nutrient concentration by leaf cutting ants and its effect on seedling and root growth. Klinge et al. summarize (again) their biomass and forest structure data from Central Amazonia. Huttel makes a valuable addition to the tiny amount of data available on root distribution under tropical evergreen forest. A paper by Malaisse et al. makes available in English some of their detailed observations on litter fall and de-composition in miombo forest in Zaire. Lugo et al. report on a series of metabolic diurnals in which they measured photosynthesis, respiration, and transpiration in various compartments (canopy leaves, trunks, prop roots, etc.) of three mangrove species in Florida. The oustanding paper in the volume is the 44 page review by l.amotte, in which he summarizes the studies of his group on a Borassu.s palm savanna at Lamto, Ivory Coast. The whole ecosystem is dissected for us: primary producers, vertebrates, inverte-

12

The papers cover such a wide range of topics and are of climate and fire.

The papers cover such a wide range of topics and are of such variable quality that the whole volume will be of interest only to a handful of readers. The better papers might have received wider distribution had they been published in the usual journals. Only the few ecosystem-level summaries which might not have otherwise appeared in English carry the rest of the volume.

KOCH, WILLIAM J. Plants in the Laboratory. The Macmillan Company, New York. 207 pp. 1973.

This manual and text is designed to be used in courses that cover the study of a broad range of plants. The book is divided into four parts each with several projects. Directions are excellent for allowing a student to proceed in-dependently. The variety of projects is intended to show the student that understanding of plants comes from a number of different approaches. The use of living material is emphasized and methods of collection are given. Also included are sources of prepared material for use if living material is not available or to supplement living material.

Part 1 deals with collection, identification and culture of plants. Thorough directions for culture of all groups from bacteria through seed plants are given. Included are formulae and methods of preparing a number of media and basic techniques of culture and isolation. A list of references for the identification of all groups of plants is included. Although not complete, it is fairly representative.

Part 2 introduces the student to microtechniques. Included are directions for the use of the microscope, preparation of slides, formulae for killing agents and stains, smear techniques for studying chromosomes, and the preparation of replicas of leaf surfaces.

Projects in Part 4 constitute a survey of the plant kingdom in evolutionary sequence. As the author states, these are the heart of the laboratory work in most introductory plant kingdom courses." All of the main groups of plants are treated with the same format, facilitating comparison. The discussion in each project includes sections on taxonomy, importance, occurrence, vegetative features, asexual reproduction, and sexual reproduction. Directions are complete but leave questions for the student. The projects not only include directions for morphological and anatomical observations but for observations of the reactions and development of living plants. The introductory material includes an outline of major plant groups showing various systems of classification, a geological timetable with the important events in plant evolution, a map showing primary productivity of the biosphere, and a list of references.

The text is enhanced by drawings of methods, implements, and plant structures and by photographs of representative species.

This manual promises to be excellent for plant kingdom survey courses. The wealth of material available allows for considerable flexibility in its use. The teacher will also welcome the collection in one manual of cultural methods for a wide variety of plants.

GAMBORG, O. L. and L. R. WETTER (eds.). Plant

Tissue Culture Methods. Available as NRCC 14383

from Publications N.R.C.C., Ottawa, Ont., Canada

K 1 A DR6. 1975. 110 pp. illus. Can. $6.00 paperbound.

"Plant Tissue Culture Methods" is the result of a group effort by the laboratory staff of the Prairie Regional Laboratory and the Biology Department of the University of Saskatchewan. They have, in a very compact form, put together a manual on plant cell cultures, procedures and application. This book is not a complete monograph on plant tissue culture methodology since it deals only with plant cell culture lines that have been started since 1963 in the Prairie Regional Laboratory. Every method is described, but the authors make very clear that the required conditions for each plant species vary and must be ascertained experimentally. This may even sound a little too optimistic because we know that some plant species have not been successfully cultured or differentiated and propagated in vitro. But the detailed procedures in each chapter may help researchers to sharpen their own methods to obtain successful cell culture lines of plant species which so far have been quite stubborn.

A table of contents opens this most useful manual, a well prepared index closes it. Each of the 17 chapters is conveniently divided in 5 parts: A. Equipment; B. Materials and Reagents; C. Procedures; D. Discussion; and E. References. The book is illustrated with diagrams and photographs. Most of the references for each chapter are from publications of the Prairie Regional Lab., but Appendix VIII is a relatively extensive bibliography on technology and application of plant tissue and organ cultures and includes many books, papers, and reviews published up to 1974. The appendices with media recipes, dry weight and mitotic index determinations, lists of suppliers of purified enzymes for protoplast production, and of laboratory equipment and glassware are very welcome. Thanks to Gamborg and Wetter for a most needed handy manual which is worth adding to our lab methodology references.
