Indigofera suffruticosa Mill. An 18th Century Specimen from Virginia
David H. Rembert, Jr.
Department of Biology, University of South Carolina
Columbia, South Carolina 29208

The Central and South American papilionaceous species Indigofera suffruticosa Mill. does not naturally occur in the Carolinas or Virginia. However, this species--the "Guatimala indigo of commerce"--was an important introduced crop plant in the 18th century in North American Colonies. It is therefore important to find an actual specimen of this species collected from the British Colonies in North America during this period of history.

This specimen was discovered in the general col1ection at the Herbarium, Department of Botany, British Museum of Natural History in London which Mr. John Lewis, P.S.O., generously made available for perusal in October, 1976. The herbarium sheet was without label; however, on the reverse side the annotation "American Septentrionalis: Virginia. Clayton" occurred. John Clayton (1694- 1773), the American botanist, spent his adult life in Virginia after completing his education in England (Berkeley and Berkeley, 1963). Clayton collected plants in Virginia and forwarded these collections to Peter Collinson in England (and on at least one occasion to Mark Catesby), who, in turn, sent them to the Dutch botanist John Frederick Gronovius (1690-1762). The collections of Clayton began arriving in Europe in 1735 and by 1739 Gronovius had published Flora Virginica (Britten, 1898). Gronovius was aided by Linnaeus in identification of the Virginia plants and Linnaeus, impressed with the work of Clayton, described the genus Claytonia to honor the Virginia botanist.

The handwriting on the back of this specimen was verified by the senior staff at the Museum as being that of D. C. Solander. Dr. Solander (a student of Linnaeus) was the 1st curator of Sir Joseph Bank's collection and assistant of the natural history collection at the British Museum in the late 18th century. It was at this time that the Clayton plants became part of the col1ection at the Museum. Previously, the plants in the possession of J. F. Gronovius, were purchased by John, the Earl of Bute, in 1778 (the Earl of Bute was, for all practical purposes, Queen Charlotte's gardener at the Royal Botanic Gardens at Kew during the reign of George III). In 1794, Sir Joseph Banks, successor to the Earl of Bute at Kew, acquired the col1ection. Solander, familiar with the collection, identified this specimen as Clayton but did not include it with the "Clayton Collection" because Gronovius had neither annotated it nor included it in his Flora Virginica.

The second edition of Flora Virginica published in 1762 included the "native indigo" or "pseudo-anil." This plant described as having yellow flowers was placed in the genus Sophora fol1owing Linnaeus' 1753 work, Species Plantarum. This native species of "indigo" was removed from Sophora in 1811 and placed into the genus Baptisia by Robert Brown (Ventenat in 1808 had first described Baptisia--see Stern, 1970). The native "indigo" in Virginia was therefore Baptisia and not Indigofera. The rationale for not including this specimen of I. suffruticosa in Flora Virginica is not known, but I would suggest that Clayton had cultivated the "Guatimala indigo" in his garden and the cultivated status was made known to Gronovius and Linnaeus and it is for this reason that it was not included. This species of Indigofera was cultivated along with the native I. caroliniana Mill. as an indigo of commerce in South Carolina in the 18th century. I would further suggest that this is the same reason (cultivated status) that Thomas Walter did not include I. suffruticosa in his Flora Caroliniana in 1788.

OF BOTANICAL THINGS PAST
Genesis - Part II
Lawrence J. Crockett
Department of Biology, The City College of New York

In 1893, after accepting the idea of a national botanical organization, botanists meeting with the Botanical Club of the A.A.A.S. took quick action. Fol1owing the recommendation of Dr. Charles Reid Barnes, they named a Committee of Ten who were then to name fifteen more, a task that was done with alacrity.

The botanists meeting at Madison, Wisconsin in August, 1894 also created a Committee on Organization and instructed it to prepare a preliminary draft of a constitution to be submitted "on the Monday or Tuesday" immediately preceding the assembly of the A.A.A.S. The Committee on Organization was composed of William Trelease of the Missouri Botanical Garden as chairman with Liberty Hyde Bailey, Cornell University; John Merle Coulter, University of Chicago; and Conway Macmillan, University of Minnesota.

The Committee on Organization was also empowered to write a letter to each of the 25 potential Charter Members asking each to say yea or nay to Charter Membership and informing each of the plans thus far determined. The "1893-Madison-Botanical-Activists" proposed three names for the new national botanical society. They were: (1) American Botanical Society, (2) Botanical Society of America, and (3) Society of American Botanists. The "Botanical-Activists" felt that the selection of the name should be left for the Charter Members to decide; they were actually in favor of name # 1.

Dr. Trelease, writing from St. Louis, on November 1, 1893, addressed the same letter to all 25 potential Charter Members. This letter became Publication #2 of the future Society. He wrote to each to ask if he or she (Mrs. Elizabeth Gertrude Britton) would accept Charter Membership and told them what the botanists in Madison had agreed upon. He made it clear that the committee felt that the aim of the new national society should be the promotion of botanical research. The letter informed its recipients that limits for membership would be rigidly

drawn and that all who were being asked to become Charter Members had been chosen because they were well known for their creditable published work. The botanists at the Madison meetings also felt that however distinguished a botanist may have been, had he recently retired or, for any reason, had not recently published, he should not be a Charter Member. This explains why the list did not include many famous American botanists. A pressure vent was included, however, as the Charter Members were told that they could later propose others for membership within the framework of the rigidly drawn limits.

While the botanists meeting in Madison that summer seemed in agreement about so many things, they were not sure where they stood on the subject of honorary memberships or, for that matter, whether there should even be such a category. They agreed to leave a decision on this subject to the Charter Members.

Early on, it was sensed that some kind of publication might eventually be required, and that the society might, in the future, have to assume the expense of publishing the research of members. Everyone seemed to feel that the society, even without an organ for the publication of their papers, would be worthy of the "best efforts of research" of each of the future members.

To prevent application for membership from "persons who were not really in sympathy with the objects of the society," it was determined that the society should charge an "admission fee." This was set at $25.00. If we recall that this fee was established in 1893, and that a professor at a good institution probably earned about $2,500, the admission fee was, indeed, large. Dues, too, were set at a high figure: $10.00. When you recall that just a very few years ago, and for many long years before that, the dues were the same $10.00, and that in 1893, that sum bought what $80.00 would buy today, one comes to understand that those 19th Century botanists demonstrated a willingness to sacrifice for the society. And keep in mind that for many years the society had no journal for the publication of the members' research, though they were expected to publish in order to remain a member.

Those at Madison thought it best that only one meeting should be held each year to be "in close association with the annual meetings of the A.A.A.S., either preceding it or immediately thereafter to avoid a conflict."

Most letters of request are not very successful, but Dr. Trelease's letter was a success and 21 of the 25 asked to be Charter Members accepted. Those who wrote in the affirmative were listed in the first article in this series (Plant Science Bulletin 23: 28-29, 1977). The national botanical society having been conceived in Madison, Wisconsin, gestated for 12 months and came vigorously into the world in August, 1894. Conceived in Madison, Wisconsin, we were born in Brooklyn, New York.

Tampa, Florida 33620

The USF campus in northeast Tampa was the site of the Second International Mycological Congress (IMC-2) in late August, 1977. More than 1200 participants with interests in fungi came from 55 countries to attend symposia, poster sessions, special interest groups, exhibits, plenary sessions as well as a reception.

IMC-2 participants gathered at the first plenary session opened by Prof. Frederick K. Sparrow who gave a delightful special presentation about Professor Anton de Bary. He described an enlightening portrayal of de Bary, the teacher. The activities of the initial day of the congress were capped by a formal reception given by the Mycological Society of America honoring the President of the International Mycological Association, Prof. C. J Alexopoulos, President of the Second International Mycological Congress; Prof. Frederick K. Sparrow; chairman of the Executive Committee of the Second International Mycological Congress; Prof. Emory G. Simmons, treasurer

PAGE NINETEEN

of the Executive Committee of the Second International Mycological Society of America; and Profs. Howard E. Bigelow and Jack D. Rogers.

The scientific program organized by Prof. Henry Aldrich included over 60 Symposia, several hundred poster presentations as well as 36 formally organized special interest groups. The poster sessions were well accepted; this format was especially appropriate for the foreign participants who thus had ample time to comprehend the visually presented material. The special interest meetings were varied and involved audience participation. Some of them were laboratory workshops and others were more seminar oriented. A large number of mycological films, arranged by Prof. Edward Haskins, were recycled daily.

Prof. Melvin S. Fuller arranged for a display of Art and Artifacts in the gallery of the University Center. There were original paintings which were used for illustrations in classical mycological books. Others included realistic and impressionistic styles. Also featured were textiles, sculpture, ceramics, wood carvings, stained glass and jewelry.

In the Special Collections Room of the University Library, Prof. Donald H. Pfister arranged an array of rare and historic books on mycological topics on loan from the Farlow Herbarium of Harvard University. Among these were early materials of mycology in North America, some dating back to 1800.

Prof. Melvin S. Fuller also organized a commercial book exhibit in a lounge in the University Center. This included some 82 new books on mycology donated by 18 publishers from around the world. After the congress, these were presented to the USF library.

Notable among the publications prepared for IMC was "A Brief History of Mycology in North America" from a manuscript prepared by Dr. D. P. Rogers. Among other documents were included two volumes of formal abstracts submitted by participants [Bigelow, H. E., and E. G. Simmons, editors, 1977. Second International Mycological Congress Abstracts Volume A-L (pp. i-xvi and 1-404) and Volume M-Z (pp. 405-786), IMC-2, Inc., Tampa, Florida].

DEATHS

Dr. Walter Brown of the Department of Botany, University of Texas, died early this year during open heart surgery.

Dr. Elmar E. Leppik of the Agricultural Research Service in Beltsville, Md. died on 4 February 1978.

An endowment fund has been established at the Botany Department, University of Vermont, to establish an annual James W. Marvin Award in Science and Conservation to recognize annually that person, organization or cause in Vermont which best symbolizes or promotes one of the activities that Jim Marvin devoted much of his life to, including areas of botany, maple research and environmental conservation. Donations should be sent to the James W. Marvin Fund, University of Vermont, in care of Dr. H. W. Vogelmann, Botany Department, University of Vermont, Burlington, VT 05401.

BOOK REVIEWS

RAGHAVAN, V. Experimental Embryogenesis in Vascular Plants. Academic Press, New York. 1977. 567 pp., illust. £21.00.
Professor Raghavan should be commended for providing us with a thorough, well-written and modern book in plant embryogenesis.

The book is divided into three (3) sections titled, I. From Egg to Embryo, II. Adventitive Embryogenesis and III. From Seed to Seedling. The first section is the largest and constitutes three-fourths of the book. In this section chapters are devoted to detailed analyses of cellular and biochemical events taking place during embryo development in vivo and in vitro. Raghavan has expertly brought together a wealth of morphological and physiological data pertaining to the development of vascular plant embryos. Previously this information was scattered throughout the botanical literature and could be obtained only through laborious library research. In this single volume the author presents material on embryo development in angiosperms, gymnosperms and ferns. The reader is thus able to relate organizational patterns in embryos from different groups of vascular plants. Considerable attention is given to recent embryological investigations, especially electron microscopic studies of developing embryos. Chapters on biochemical and physiological aspects of embryogenesis are included and in these current information bearing on the molecular and hormonal control of embryogenesis is reviewed. Several chapters are devoted to various aspects of growing isolated embryos, ovules, ovaries and seeds in nutrient culture. For some years Raghavan's personal research was in the field of embryo culture and this experience provides him with important insights into the problems remaining to be solved and logical approaches to the solution of these problems.

The second section of the book contains two chapters dealing with adventitive embryogenesis. The first considers the induction of diploid embryoids from plant tissue cultures and the second details the accomplishments in generating haploid embryoids employing the more recent techniques of culturing embryo sacs, microspores and anthers. Both chapters are complete, authoritatively written and provide an up-to-date review of work in this field.

PAGE TWENTY

The third and final section of the book covers the topic of seed dormancy and seed germination. While these topics are not treated in as much depth as some of the other subjects, this reviewer is pleased to see the material included in a book on embryogenesis. Current views on dormancy mechanisms in a variety of seeds are presented and postulated physiological and biochemical mechanisms for overcoming dormancy effects are considered. A short introduction into the biochemical events occurring during seed germination and the molecular mechanisms controlling these events concludes this section.

Readers will find the book interesting and free of major errors. It contains over 100 pages of references to original research articles cited in the text. In addition, an appendix provides recipes for a variety of nutrient media useful in culturing embryos and embryoids.

All developmental botanists and physiologists will want to read this book and many of them will find something new or interesting. The book would be an appropriate text for advanced courses in plant embryology and development. The book should also be interesting reading for individuals in horticulture, floriculture, and plant breeding. Students especially should read it carefully for they will find that many important experiments remain to be done in this exciting field of botany.

In summary this is a scholarly book and will remain an important contribution to botany for a long time. Unfortunately, at a cost of approximately $37.38 the book probably will not find its way where it will do the most good and that is in the personal library of teachers and researchers. Nevertheless, it belongs in every botanical library.

LANGLOIS, ARTHUR C. Supplement to the Palms of the World. The University Presses of Florida, Gainesville. 1976. $25.00.
This most welcome supplement to McCurrach's Palms of the World covers over 100 rare and poorly known genera not included in the original volume. The style of the text is informal, such that it can be read by any layman, but the book contains a wealth of information useful to the professional botanist as well. Each genus is illustrated, a very useful feature of the book, but a number of the illustrations are unfortunately rather poorly reproduced, particularly some of those copied from earlier publications. Most, however, provide excellent first glimpses of seldom seen palms.

Among the genera covered, there are a number that are no longer recognized. This is deliberate on the part of the author and allows for coverage of some groups of palms that might otherwise be overlooked. However, the author does not always make it clear when he is using such an obsolete name (one must check an appendix in the back for this), and there is the danger that readers will mistakenly apply these names to plants in the field or garden.

The few flaws in this book do not, however, seriously detract from its value as a storehouse of hard-to-find information. Every student and lover of palms will want to have a copy.

BOGORAD, L. AND J. H. WEIL (eds.). Nucleic Acids and Protein Synthesis in Plants. Plenum Press, N.Y. 1976. 417 pp., illust. $39.50.
Current trends in plant nucleic acid and protein synthesis are often difficult to keep abreast of because of the rapidly expanding literature. The reference-text by Bogorad and Weil has succeeded in bringing together papers written by some of the current research leaders involved in these two large but interrelated fields. The twenty-four papers presented cover a wide gambit of topics, thus, providing a general overview which is divided into six major areas: 1. organization and replication of nuclear and chloroplast genomes, 2. transcription, 3. translation, 4. synthesis of nucleic acids and protein by organelles, 5. control of nucleic acids and protein synthesis by hormones and environmental factors, and 6. foreign DNA and plant cells.

Each article is written in a rather clear textual manner and is accompanied by many charts, tables, graphs, and pictures which enhance the clarity of the book.

In general the text, despite several typographical errors, would prove useful to anyone new to the field or to those veterans who desire a brief review.

ROST, THOMAS L. AND ERNEST M. GIFFORD, JR. (eds.). Mechanisms and Control of Cell Division. Dowden, Hutchinson and Ross, Inc., Stroudsburg, Pennsylvania. 1977. $30.00.
In these days of increasing specialization, the content of this volume on a seemingly restricted topic is so broad that it was necessary to divide it into three parts: I. Cell Cycle Regulation, II. Nuclear Structure and Chromosome Movements, and III. Mechanisms of Cell Division. And even so, part II should have been divided into nuclear studies and studies on mitosis. The book is a mixture of reviews and results of current research and this reviewer would categorize the twelve articles as four reviews of specific topics, four reviews of work primarily from the authors' laboratories, and four articles that would be published normally as research papers.

It is unfortunate that the many photographs, particularly the electron micrographs, were not printed on a high gloss quality paper. Also, there are minor typographical errors throughout the book (e.g., on pages 46, 126, 162, 171, 223, 234, 240, 247, 309, 321, 366, and 368). On page 251 it is stated that transport by suctorian tentacles may be fifty times faster than typical non-kinetochore transport or chromosome movement, whereas the figures given indicate that the rate would be 400 to 1200 times faster.

The article by L. R. Gurley et al. on Sequential Biochemical Events Related to Cell Proliferation is an up-to-date summary of their studies, using synchronized Chinese hamster cell cultures, of cell cycle changes in deoxyribonuclioside triphosphate pools, histone synthesis, and histone phosphorylation, as well as sequential f1 phosphorylation events, mitotic phosphorylation of histone f3 subfractions, etc. They interpret their studies as reflecting specific changes in histone structure which are related to changing the structure and function of chromatin. They envision "an orderly progression of specific histone modification as necessary for the proper functioning of chromatin as cells progress through their proliferation cycle." Angeline Douvas and James Bonner provide a welcome addition to the outstanding contributions of Bonner's group on chromosomal nucleoproteins. They report identification

PAGE TWENTY-ONE

of six polypeptides of the nonhistones as myosin, actin, two tropomyosin subunits, a myosin breakdown product and tubulin. While they acknowledge the possibility that these may be cytoplasmic contaminants, they believe that their results strengthen arguments in favor of a structural role for these major proteins. Thus, evidence is accumulating that an actomyosin system may be generating the motive force in plant cells in such processes as cytoplasmic streaming, chromosome movement, and chromatin condensation.

D. E. Fosket reviews regulation of the plant cell cycle by cytokinin and concludes: (1) "In actively dividing cells which require cytokinin for growth, the hormone specifically regulates processes either in G2 or in the transition from G2 to mitosis," and (2) "The events of the cell cycle are results of a genetically determined program. Cytokinin is not involved in the transcription of this program. Other factors, possibly auxin, initiate the reading of the genetic information for the cell cycle. However, cytokinin is necessary for the translation of certain messages into effector molecules (proteins) which must act in G2 for the cycle to be completed." J. Brent Loy emphasizes the effects of gibberellin on cell proliferation, but also mentions briefly its possible interaction with other plant hormones in controlling cell division. He notes that there is a surprising lack of research on hormonal regulation of cell proliferation in primary elongating meristems, considering their importance in shoot development. Thomas L. Rost concludes that stress expression is through: (1) inhibition of mitosis and the formation of chromosomal and mitotic aberations, (2) induction of radial enlargement of stressed organs, and (3) cell cycle accumulation patterns. He believes that it may be justified to apply Jack Van't Hof's Principal Control Point Hypothesis, developed through studies of nutritional stress, to stress effects generally, regardless of source.

Walter Nagl "summarizes the available data on man, animal, and plant species, whose nuclei undergo structural changes during interphase and very early prophase." He also discusses possible reasons for the morphological changes of chromatin during the cell cycle, as well as their functional significance. He concludes that: (1) "The nuclear structure may well be suited to serve as a marker of certain cell cycle stages, at least in a number of organisms," and (2) "the chromatin structure can indicate quite accurately the life history of a nucleus in terms of the type of cell cycle from which the nucleus has originated." James P. Braselton has characterized persistent nucleoli in mitosis in root tips of mung bean at the ultrastructural level and reminds us that persistent nucleolar behavior is more common in higher plants than is generally believed.

It is now widely accepted that microtubules playa vital role in chromosome movement, although it has not been established that they actually provide the motive force required. Even though much attention has been devoted to establishing the sites of initiation of microtubules in the mitotic spindle, Peter K. Hepler emphasizes that little is known concerning, "The conditions necessary, and the structures involved in establishing those conditions, for the formation of the microtubules upon their initiating sites." Based in large measure on his research, he promotes the idea in this chapter that the membranes are the cellular inclusions which regulate the levels of divalent in vivo and thereby participate in the control of the formation of spindle microtubules. With the growing realization that an actomyosin system may also be involved, the importance of divalent cation concentration control, both spatially and in time, is assured. The elegant studies by Hepler and co-workers on plant cells together with similar work by P. Harris on spindle of sea urchins suggests that this exciting new area of research will develop rapidly.

Andrew Bajer and his wife, J. Mole-Bajer, have, over the past quarter of a century, made an exceptionally thorough study of chromosome movement in endosperm cells of Haemanthus katherinae. In the past few years, they have become convinced that lateral interaction of microtubules ("Zipping") can, and probably does, generate the force required to move chromosomes throughout mitosis. Based on experiments on the effects of low temperature and glycols, they believe that sufficient evidence exists that active zipping takes place both in the half-spindles and the phragmoplast. Even if zipping occurs, however, it is still to be determined that it provides the motive force required to move chromosomes. Proponents of the dynamic equilibrium model, the sliding filaments model, and the increasing number who believe that an actomyosin system provides the force, will ensure that the zipping model is given a rigorous examination.

G. Gimenez-Martin, C. de la Torre, and J. F. López-Saez' review deals with "cell proliferation in the root meristems of higher plants, placing particular stress on its dissection by means of chemicals." They also effectively use polynucleate cells to dissect the cell cycle. Based on the properties of stained nucleoli, they are able to distinguish four types of cells that represent different stages of the nucleolar cycle found in a meristem population. They conclude that the cycle rate in meristems is inversely proportional to temperature, while the relative duration of the different cycle compartments remains constant under steady-state conditions. They stress that the apparent continuity of the cell cycle is sustained by a series of controls, some running in sequence, others in parallel.

The work on mitosis in Euglena and Phacus by J. D. Pickett-Heaps and K. L. Weik, utilizing light, scanning, and transmission electron microscopy, reveals that "The structure of the spindle and probably the mechanisms involved in chromatid separation are like that of many other eucaryotic organisms." They did find that Euglena gracilis chromosomes possess kinetochores, though they did not find distinct ones in Phacus. The spindle remained entirely closed during mitosis in both organisms and the basal bodies were never seen at the broad poles of the spindle but always laterally beside the nucleus.

In his review meiotic and mitotic divisions in the Basidiomycotina, Kenneth Wells concludes that the essential features of classical mitosis and meiosis occur in this taxon, and that nuclear divisions in this taxon and the Ascomycotina differ in several important features. For example, he reports that most studies of meiosis in the Ascomycotina have reported an intranuclear spindle whereas the majority of studies of both mitosis and meiosis in the Basidiomycotina have reported that the nuclear envelope is interrupted during some phases of division. In terms of internal structure, he believes that the available evidence suggests, except for the Uredinales, that the relative number of cytoplasmic microtubules arising from the ascomycete spindle is greater than those arising from the basidiomycete spindle. He discusses the effect of space restrictions on both the shape of the mitotic spindle and the asynchronous disjunction of the chromatids during mitosis and meiosis.

In summary, this book, as the editors state in the Preface, is a compendium of several areas of cell cycle research, especially those dealing with plants. It should be useful for researchers and advanced students interested in cell behavior.

MASTERLERZ, J. W. The Greenhouse Environment: The Effect of Environmental Factors on Flower Crops. John Wiley & Sons, N.Y. 1977.629 pp., illust. $18.95.
The preface states that this book was written for students planning careers in greenhouse management. The author has done an excellent job of meeting that objective. The major defect in the text is the confusing mixture of fps and cgs units; one figure will use of, the next one °C; inches and grams appear in the same table, etc.; and there seems no particular merit in using microns and millimicrons and nanometers as units of wavelength.

It is surprising, especially in a book dealing with flower crops, to find no mention of Agrolite or low pressure sodium lamps in the radiant energy section. One also wonders why measurement of photosynthetically active radiation is not discussed; especially since flux density of PAR currently seems to be the most acceptable method of measuring the radiant energy used for plant growth.

In the chapter I would have preferred a larger section on ozone, the most prevalent of the phytotoxic gases, and S02 which is sure to be a greater problem with increased use of coal. A key to symptoms of phytotoxic gas damage, similar to the one the author included for nutrient deficiencies would also have been useful.

The shortcomings of the book, however, are more than balanced by the wealth of information invaluable to those learning about greenhouse management. In fact this book should be required reading for all floriculture students as well. I also suggest that very few of us that use greenhouses extensively, for research as well as application, would fail to benefit from a perusal of it.

MARSH, R. W., R. J. W. BYRDE, AND D. WOODCOCK. Systemic Fungicides. Longmans, Inc., N.Y.
1977. 401 pp., illust. $25.00.
Systemic Fungicides will be a useful reference for plant pathologists in general and especially for those concerned with chemical control of plant diseases. The book has been expanded and updated from the first edition published in 1972. It follows the same well-organized format of the earlier book, but three chapters have been added as well as an alphabetical listing of systemic fungicides in commercial use. The added chapters are Metabolism, Efficient Use of Systemic Fungicides, and Results in Practice-Forestry. The Forestry section is a valuable addition because of the great potential for systemics in treating forest diseases. However, the bulk of this chapter, as well as the primary success story, deals with Dutch elm disease, which some may argue is more of a horticultural problem than one in forestry.

Each chapter has been expanded to present new information; approximately one-third of the references were published after 1972. Many chemicals are discussed which are not in commercial use, but their inclusion is valuable for historical and comparative purposes. One omission notable to this reviewer is the absence of the material "Sclex" which was reported in the first edition. This fungicide has been demonstrated to have excellent systemic qualities in controlling some difficult diseases. Overall, however, the book is well written and organized and will be a help to all involved in plant sciences.

ANDERSON, FRANK I. An Illustrated History of Herbals. Columbia University Press, N.Y. 1977. 270 pp., illust. $16.95.
The author, Honorary Curator of Rare Books and Manuscripts at the New York Botanical Garden, has utilized the splendid botanical resources of the Garden and of other institutions to prepare a book designed less for the professional bibliographer, librarian or botanist than for that hypothetical (and possibly mythical) entity, the educated layman. In keeping with this, the text is not particularly botanical, but flows smoothly and occasionally humorously, providing the reader with a fine overview of the era of herbals.

This volume must be evaluated against the now classic book by Agnes Arber, Herbals: Their History and Origin, published in 1939. Arber's was a scholarly work in which the author evaluated not only the herbals themselves, but also the botany, the history of the period and the subtle rivalries that existed among men and nations. Her book was bigger in scope and design and stands as an important document in the history of botany, medicine and pharmacology. Although Anderson touches upon these matters, he does not attempt to expand, extend or supplement the beautifully written panorama provided by Arber. Although the present book contains many more illustrations than does Arber's, and is therefore of botanical value, the Columbia University Press should be censored for their decision to use cheap paper which failed to give clean, crisp illustrations. These, the most important feature of the book, are poor.

CAMPBELL G. S. An Introduction to Environmental Biophysics. Springer-Verlag, N.Y. 1977. 159 pp., illust. $8.90.
A new book, An Introduction to Environmental Biophysics by Gaylor S. Campbell, is a well written expose of the physical microenvironment of living organisms. The author stresses the underlying concept of the biophysical ecology of energy exchange, particularly mechanisms of heat transfer. The environmental variables affecting behavior and life are discussed in chapter format including sections on temperature, moisture, wind and radiation. Throughout the book ample illustration is given in the form of well-chosen figures, examples of the comparative effects of these environmental parameters on both plant and animal, adequate mathematical description, and problems for students to test their grasp of the material presented.

Approximately one-half of the book treats selected areas of the biophysical interaction of plants and animals with the environment, although traditional biologists would probably not find much "biology". The concept of energy budget as well as energy and mass exchange unifies discussion on animals, plant leaves and canopies.

The book may be used as a text in advanced under-graduate and graduate level courses in which the environment or biophysics is the theme. In some portions of the book, only very specific topics are covered; for instance, Nobel's book, Biophysical Plant Physiology, is perhaps a better choice for overall discussion of plant interaction with the physical environment. All in all, I recommend this book as a basic reference source or text in the area of environmental biophysics.

LIONNI, LEO. Parallel Botany. Alfred A. Knopf, N.Y. 1977. $12.95.
Devotees of Alice in Wonderland and Tolkien now have a new field to explore--that unique, but widely distributed, flora described so vividly and so expertly illustrated in Parallel Botany. The illustrations are particularly remarkable since many of the taxa are invisible, most disintegrate with human touch and they arc resistant to the most sophisticated photography.

Growth does not occur in this remarkable group of plants since they represent a "permanent stoppage in time". This "immobility in time" results in a "corresponding immobility in space" so that the taxa do not change dimension as one approaches them. Another result is that there is no problem for survival and the plants of parallel botany have no need for color and thus display a range of blacks from "tête de nègre" to "bois builé". One species, Tirillus silvador, has the extraordinary ability to produce shrill, whistling sounds audible to two or three hundred meters.

Fortunately, in spite of the obvious difficulties in studying and preserving this remarkable group of plants, the author has provided 33 drawings of the various taxa ranging from algae to higher plants, some parasitic, some aquatic, and some known only from fossil casts.

This unparalleled account of the discovery of parallel plants, the research problems they present, the proceedings of congresses (particularly the nomenclature sessions), the influence of this unique flora on art, archaeology, legends, linguistics--in fact on all aspects of modern life--is what one reviewer has called "the definitive word on the botanical counter culture". Every botanist should become familiar with the breadstick-like tirils, the strangler tirils (formally known as the "phab" group from alpha beta), the woodland tweezers, the unusual floating Sigurya natans, and their marvelous relatives. Unfortunately, their invisible nature prevents us from cultivating them but, on the other hand, there is no danger of them becoming noxious weeds.

BALBACH, M. K., L. BLISS, AND H. J. FULLER. A Laboratory Manual for General Botany, 5th Edition. Holt, Rinehart and Winston, Inc., N.Y. 1977. 393 pp., soft cover. $6.95.
This is an excellent manual for a standard freshman Botany I-II course. Its thirty-six exercises are divided into structure and function of seed plants (21), plant kingdom (12), and genetics, ecology, and taxonomy (3). Page references are provided to relevant sections of six botany texts. Each exercise is preceded with introductory material, conducted via a number of activities and concluded by questions. Pages are perforated so students' work can be handed in.

All the tried, true, and time-honored examples and activities are here. The student is taken through seeds, cells, meristems, roots, stems, twigs, wood, leaves, flowers, fruits, photosynthesis, digestion, respiration and plant movement. The dramatis personae of the plant kingdom include bacteria, Saprolegnia, Rhizopus, Peziza, Saccharomyces, Coprinus, Chlamydomonas, Ulothrix, Oedogonium, Oscillatoria, Fucus, Mnium, Sphagnum, Marchantia, Psilotum. Lycopodium, Selaginella, Equisetum, Polystichum, Pinus, Lilium and many others. The directions are clear, living material is prescribed more often than not, and the illustrations are well done.

The only disquieting note is that it all bears an uncanny resemblance, in considerable detail, to the Botany I-II course I first taught twenty years ago. The traditionalist in me is delighted that people are still teaching and learning the good things, the radical is wondering where the discipline has been these twenty years. In any case, if you have use for a traditional, orthodox, lab manual, this one is superb.

GOOR, A. Y., AND C. W. BARNEY. Forest Tree Planting in Arid Zones, 2nd edition. Ronald Press, N.Y. 1976. 504 pp., illust. $17.50.
This is a thorough revision of what was originally a manual of practice by the senior author and published by F. A. O. It is based on long experience and observation of the difficult problems in establishing trees in arid and semi-arid regions (those with less than 600 mm of annual precipitation) throughout the world. The descriptions of kinds of vegetation, climates, and techniques, ranging from seed production to caring for established forests are both authoritative and lucidly detailed. There is a comprehensive account of the ecological characteristics and treatment of virtually all of the species commonly propagated. It describes the management of tree plantations for production of commodities, amelioration of the environment, soil stabilization, and visual amenity. If this excellent book has any shortcoming, it is that it tells what to do without often telling why. It is clearly the best book on the topic and as good as any on forestation techniques in general.

WERNER, D. (ed.). The Biology of Diatoms (Botanical Monographs, Vol. 13). University of California Press, Berkeley and Los Angeles. 1977. 505 pp., illust. $32.50.
This book brings together much valuable information on the diatoms. The 12 chapters were written by authorities in their fields and range from ecology and taxonomy to silicate metabolism and heterotrophic nutrition. The chapters on movements and sexuality are particularly thought-provoking and will doubtless stimulate further research in these areas. Dr. D. Werner has also supplied an introduction which summarizes the most widely used classifications of these organisms as well as containing some interesting miscellaneous information. The second part of the introduction is a contribution by Dr. G. R. Hasle on the use of electron microscopy in morphology and taxonomy. This subject should have merited a chapter of its own with a more extensive text.

Most contributions are well written and are extensively referenced. A subject index and an organism index for the whole book are useful features. My principal criticism of this monograph is that not enough use is made of micrographs and those that are present do not appear to have reproduced as clearly as might have been wished. However, this is only a minor drawback and should not be allowed to detract from a book that will become indispensable as a reference work.

RICHARDSON, W. N. AND T. STUBBS. Plants, Agriculture and Human Society. W. A. Benjamin, Inc., Reading, MA. 1978. 353 pp. illust.
The 22 chapters of this tightly-written paperback are divided into five Units, treating successively: some fundamentals of taxonomy, evolution and plant morphology; the origins of development of agriculture; traditional economic botany; aspects of ethnobotany; global food production. Designed as a textbook in introductory botany or " . . . in any other course which deals with the interrelationships of plants and humans," the book includes suggested readings and a modest index. It is well written with excellent illustrations.

This is a difficult book to summarize, primarily because it attempts to cover huge blocks of information. The scientific and professional vocabulary is advanced and since few of the terms are defined, it may be too sophisticatcd for non-botany undergraduates or horticulture majors. The authors have a great deal of important information to present and they must, in a short book, assume considerable pre-knowledge of classical botany, economic botany, anthropology, history and political sciences. Graduate students and professionals will, however, find the book valuable and fascinating.

The Unit on economic botany is probably the least satisfactory. It gives one the impression of a condensed summary of Shery's Plants for Man without the depth that Shery provides. In general the photographs used in this section are almost useless; an underexposed picture of a peanut plant adds nothing to a discussion of legumes and an overexposed photo of pistachio nuts is equally banal. The Unit on ethnobotany includes an unnecessarily complex section on ethnobotanical methods down to the choice of clothing to be worn. Not infrequently, the reader is caught up short by inclusion of material that seems unrelated to previous or subsequent sections. It sometimes becomes difficult to separate material of basic importance from the trivial; more space is devoted to flax than to cotton, and charcoal production is given the same weight as paper production. The role of plant disease in food production and the significance of photoperiod, thermo- period, and vernalization in determining the range of crop-growing lands is slighted in favor of information on dietary innovation or geological eras. Regretfully, it is here noted that wheat rust is not caused by Claviceps. The potential of high-lysine corn and information on essential amino acid requirements is absent.

Nevertheless, the book is recommended as a useful reference for faculty who want to extend their own knowledge and believe that it is vitally important to provide students with a glimpse of the role of plants in the survival of the peoples of the world.

FRYER, J. D. AND S. MATSUNAKA (eds.). Integrated Control of Weeds. University of Tokyo Press. 1977. 262 pp. $19.50.
This book is a compilation of the proceedings of an international symposium from the Fifth Asian-Pacific Weed Science Society Conference (Tokyo, 1975). Ten chapters, each written by a noted authority, summarize various weed control aspects. Five chapters deal with integrated weed control in rice, upland crops, tropical plantations, pastures, and aquatic areas. Chapters on damage to crops by weed competition, biological weed control, herbicides and environmental problems, and economic considerations of weed control in rice are included. The final chapter discusses problems, future goals, and directions of weed control technologies.

In spite of the brevity of the book, it presents an up-to-date overview on this subject, supplemented with tabular and graphic data. Each chapter is prefaced by an abstract, and is terminated by a brief discussion and an ample reference section. Indices of weeds and herbicides are also given for quick reference. This book should be useful for those interested in the economics and efficiency of world agriculture and particularly for persons involved in weed science research and those teaching weed science. Although integrated weed control has been and is being used, as this book points out, there is a need to extend its use in both highly developed and underdeveloped agricultural areas of the world if we are to reduce the cost of food production and meet the challenge of feeding the world's exploding population in the future.

MATTSON, W. J. (ed.). The Role of Arthropods in Forest Ecosystems. Springer-Verlag, New York. 1977. xi + 104 pp., 28 fig. $15.80.
This volume contains twelve papers presented at a symposium during the 15th International Congress of Entomology (1976). The contents are equally divided between decomposition processes and the plant-herbivore relationship, and treat the influence of arthropods on important community processes such as succession, nutrient cycling, and pollination. One of the more important concepts emerging from these papers is that arthropods have important effects on community organization and function that are not explained by how much plant material is being eaten or how much detritus is being processed. Anyone with an interest in community ecology will find new and useful information in this book.
