Environments of Men and Molds—Another Look at The Emperor's New Clothes1

Ralph Emerson
University of California, Berkeley


President Galston, honored guests. members of the Botanical Society of America, Good Evening! This is a great honor you do me and I thank you for it. But, make no mistake, it is also a forbidding task especially because, like Lawrence Bragg, I have always held to the belief that speeches should be spoken not read, no matter how large or distinguished the gathering. On this point Sir Lawrence said, "I feel that to collect an audience and then read one's material is like inviting a friend to go for a walk and asking him not to mind if you go alongside him in your car."' Many speeches, of course, are even better left unsaid. I must confess to the warmest admiration for that former officer of ours who, so the story goes, tendered a check for some thousands of dollars to our treasurer and sent his regrets to the guests who had assembled for the annual dinner. He was a man of courage and doubtless his non-speech will be remembered long after most BSA dinner speeches are forgotten.

Well here, then, is the question that confronts me. Shall it be the ways of man and the social implications of our profession, about which I have many thoughts and deep feelings but little knowledge and no great powers of persuasion? Or do I talk about the ways of those molds I love so much and about which I have some knowledge and great enthusiasm? The former approach has certainly been the more popular in years past, and a long line of distinguished speakers has linked botany for us to the changing world, educational policy, the responsibilities of citizenship, the Soviet Republic, biological ad-ministration, and other equally weighty sociological goings-on. However, there have been a few hardy souls who stayed closer to their knitting and delighted their audiences with spritely tales of dung-inhabiting bryophytes from Arctic wastes, microscopic algae to be won from God's green earth, or the gastronomic woes of idiotic grass-hoppers chomping on idioblastic cells. My hat is off to these men! Wouldn't most of us agree that plants are more interesting than people?

At all events, my own decision, for better or worse, was to try mixing the two. I recalled how Professor "Cap" Weston in days past had woven plants and people together in his delightful essay on "Lower Plants and Higher Education."' Perhaps I too might draw a contrast between men and molds. So the title of my talk tonight is: Environments of Men and Molds—Another Look at "The Emperor's New Clothes." I shall endeavor to show that molds have done far better than man in adjusting effectively to the environments in which they have evolved. To botanists this will come as no surprise. You will recognize that molds have been around and on the job for a very long time in contrast to man's brief and ex-plosive efforts. On the other hand we might have sup-posed that man, as a rational, reasoning, and imaginative animal, would surely have outdistanced the fungi. That he has not may well be because he is so prone to the swindle, the wooden nickel, the soft sell.

From this stems the second part of my title. As Harry Fuller,4 another Botanical Society President, recognized on an earlier occasion, there has never been a more piquant and persuasive account of the swindle than Hans Christian Andersen's fairy tale "The Emperor's New Clothes." As you will remember, two confidence men came to town offering to weave for the emperor such beautiful—and expensive!—cloth that it could only be seen by the capable and pure in heart. If you were ignorant, slovenly, generally incompetent, you would not be able to see this fabulous material. Of course they wove nothing, although going through elaborate motions in pre-tense and exhibiting the cloth for all to see when it rolled off the loom. Naturally, too, no one from the Emperor and his Chamberlain on down to the chief bottle washer and man in the street wanted to admit he could see no cloth for none could admit to being ignorant and incompetent. So, when the Emperor stepped forth to exhibit his new outfit, he was received by all with great acclaim.•' There is no saying how far that hoax might have gone had not a small boy in the crowd cried out with glee, "Look, Mommy! The Emperor has no clothes on!"

We shall return to the men and the Emperor shortly but first let us examine the molds and consider how they have adapted themselves to two unusual environments.

Fungi Adapted to Extreme Environments

My interest in these particular adaptations arose because of an abiding desire to grow the living fungi in the laboratory and thereby study their activities. In each case a fundamental aspect of evolutionary adaptation had to be


recognized before the proper conditions for growth could be provided in the laboratory. The first circumstance arose during World War II (Fig. 1) when it was my


good fortune to be associated with Drs. Paul J. Allen and C. B. van Niel in an investigation of the rotting of guayule. The rubber from this shrub could be brought to an acceptable quality if the plants, whole or chopped, were first subjected to a microbial decomposition.`' Molds were important agents in this process and some of the most conspicuous and active ones could, at first, neither be grown in the laboratory nor be identified in the litera-

ture. It soon became apparent that, like compost or manure piles, guayule rets underwent self-heating and we were dealing with a small group of then little-known fungi adapted to grow at unusually high temperatures. They grew scarcely at all at room temperature, throve at 45-50 C, and were often active even at 60 C. Out of this came ultimately a full account of thermophilic fungi.? The point of importance here is that among the thousands of fungi in the world a few have become adapted to grow in a habitat where the competition from their fellows is virtually eliminated by high temperature. Not only are the thermophilic fungi able to grow at elevated temperatures, what is more significant they do not grow at temperatures which favor their would-be competitors.

The second example of adaptation was even more striking. In a search for tropical water molds in Costa Rica some ten years ago, I came across the extraordinary phycomycete we have named Aqualinderella f ermentans.s Unlike its close relatives, and for that matter all previously known fungi, A. fermentans showed no growth of plated zoospores in pure culture until it was placed in a chamber containing 4 per cent CO,. Moreover it grew best in an atmosphere of Hs or N_ essentially devoid of oxygen and with 20 per cent CO2.° Whereas the vast majority of fungi are strongly aerobic, A. fermentans is a facultative anaerobe with an obligately fermentative energy metabolism. Here is a fungus specially adapted to grow on submerged fruits in warm stagnant waters where the levels of O2 are so low and the levels of CO2 are so high10 that all the common fungi are eliminated from competition. Once again we find a fungus superbly adapted to live under those very conditions that are inimical to its competitors.

These two examples can serve to illustrate how fungi have evolved to fill countless habitats and environments over the earth's surface. Down through the ages they, like all the other living things—except man—have adjusted to the world in which they live. Now let us turn to man, man who prides himself on his capacity to shape the environment to suit his needs. Here again I have selected two environments, one small and close to home, The University Environment, the other wide and all about us, we may simply call The World Environment. I shall take the University first and ask you to recall the Emperor. For the question before us is whether the environment man has created is a good one or whether he has sold himself a bill of goods? Is the Emperor's suit made of whole cloth or is it shot full of holes? Before you jump to the conclusion that such large questions are outside the purview of a mycologist, let me remind you that mush-rooms and toadstools have always had an intimate connection with man's folklore, his most private affairs, his life and death (Fig. 2), his daily shopping (Fig. 3), his space exploration (Fig. 4), and even his wars (Fig. 5).

The Little Swindle—The University Environment

An environment that is of great personal importance to most of us here is the University. Despite its small size in the general scheme of things, we know that the University carries a tremendous social responsibility and, in the long run, must be the source of information and ideas to expose any swindles in the world environment we will turn


to last. It is doubly important, therefore, that the University itself be alert to possible hanky-panky within its own walls. Nothing is more demoralizing than intramural swindles and nothing can bring down the house of intellect nore quickly from its key position in society at large.

Despite all that may be said—and a lot has been said


universities are institutions of learning in which, it students and teachers work objectively together to dis the truth, advance the frontiers of knowledge, and the coming generations of truth seekers. This last is portant. Indeed it is generally conceded to be the ori, function of a university. In an editorial" in 1964 em "The Appropriate Function of a University," Abelson st it very simply: "Obviously it [the university] should primarily for educating the young. This is the one fund which it can uniquely perform and, in the long view, most important." We would also agree that graduate even advanced undergraduate education is integrally sociated with research. The next development, howev can be traced in Garrett Hardin's volume on "Nature a Man's Fate." 12 "As it became generally recognized," . writes, "that an important fraction of the world's researc in pure science was done by academic men, administrate defined research as parr of the job and made productivit in research a criterion for advancement." Furthermore he continues, "the consequences of this meddling hay, been about what one would expect. There is now a ten dency to choose research] projects that are pretty sure ro give quick results and to avoid questions on tabooed subjects." And finally he adds: "As research has become more expensive the academic man has had to develop a talent for begging." The plot thickens considerably in this sequence when we conclude with these pithy comments by Nobel Laureate J. J. Thomson who pointed out that ".. . if you pay a man a salary for doing research, he and you will want to have something to point to at the end of the year to show that the money has not been wasted. In promising work of the highest class, however, results do not come in this regular fashion, in fact years may pass without any tangible results being obtained. . . . The only thing to do is to pay him for doing something else and give him enough Ieisure to do research for the Iōve of it.""

Now where does this leave us? Ostensibly the some-thing else most of us in universities get paid for is teaching. However, the quality and contribution of a teacher are hard to judge, research is easier to measure or at least seems so, and furthermore the distinction of the University rests upon the distinction of its research so, ipso facto. research becomes the yard-stick for promotion. We have then reached a unique position for as a writer in Science noted recently, we are the only profession that is hired to do one thing—teach—and promoted to do another—research.

As a logical consequence of these several developments, the research pressures in many if not most universities have become heavy, so heavy in fact as to detract from teaching effort. Evidences of a serious imbalance in the educational applecart are all around us. In the editorial by Philip Abelson noted just above" he put the situation unequivocally: "Under the present rules of the game," he says, "any scientist who teaches when he can do research must be unusually public-spirited or blind to his own interest. The result is to demean teaching. How," he asks, "can a professor approach a class with enthusiasm and adequate preparation if he is convinced that education of under-graduates is a secondary function of the university?" In a recent lead editorial in Nature headed "How lnnr ,,,_


the universities last?" the following statement appeared: "One consequence of a more serious attempt to cater for the real educational needs of students is likely to be that faculty members have less time for their own pursuits—research for example."14 A staff writer in Science, discussing the competitive aspects of faculty recruitment, is


equally blunt. ". . . faculty members," he says, "should be aware that the picture which increasingly emerges when professors discuss their condition is one of men who are interested in using the universities primarily as bases for their own activities, research, and well-being, and only secondarily as places to teach students. On the other hand, most people outside the university (as well as most students) believe that universities should be primarily teaching institutions."':' In a most entertaining column in the popular press Art Buchwald presents "One Man's View-point on Campus Revolts." "The reason," he quips, "the college students are doing so much demonstrating is that there is no one in the class to teach them anymore." m And, finally, coming home to the fountainhead of student unrest, one of the numerous FSM (Free Speech Movement) -spawned committees at Berkeley concluded last spring ". . . the national and international reputations of both the University and its faculty rest on published re-search, not on teaching . . . furthermore, the individual's professional peers, the colleagues in his discipline through-out the world, are almost exclusively concerned with the individual's research activities and thus pay no heed to his

excursions into the realms of education. ... he is aware that neither his institution nor his colleagues seem to attach much value to teaching."'' They went on to state "We think ... that a 'credibility gap' exists between official statements about the central importance of teaching and the day-to-day operating priorities of the University." Now "credibility gap" is merely the modern way to express doubt about the cloth of the Emperor's new clothes. The implication is clear that someone is tactfully trying to expose a swindle.

The "Publish or Perish" philosophy carried to extremes has a variety of other anti-adaptational effects in the university environment. The struggling young scientist—and not so young too—faced with a need to provide the requisite list of titles come the end of each academic year has resorted to a variety of practices that are at least open to question. A sound block of research, representing a coordinated monographic unit, is purposely fragmented into bits to provide additional titles, each with its overlapping—frequently identically worded—introduction, materials and methods, and bibliography. The series appears as "The path of nitrogen, parts I to XLVIII" (to borrow from my humorous friend, R. Arnold Le Win) .'s Incidentally, each of the 48 parts, assuming it is worth noting, must have a separate index card entry; each, assuming it is worth having, requires a separate reprint request; and each must be housed and kept track of in a reprint col-



lection, assuming such a collection is now worth the effort. Surely a strange adaptation to an environment already complicated by the information explosion. Whatever James Bonner may say about the bad old days, there was some-thing very satisfying about an afternoon spent in the quiet of the Farlow Library reading a 150-page paper with one title, one author, and one set of conclusions representing perhaps the culmination of five years of work. No wonder we shall need data storage and retrieval machines to keep track of those one-page papers that are upon us.

Then there is the matter of authorship. Aside from the team efforts whose authorship approaches in column inches the text of the paper itself, there are the graduate students. Again in those bad old days, professors of biology at least, if not chemistry, were proud to have their students publish their doctoral theses under their own names. Not so today. A young professor is missing out if he doesn't avail himself of this opportunity for swelling his publication list. Indeed a young colleague made it very clear to me not long ago that the primary purpose of having graduate students was so that they could get the work out for you and keep those publications rolling.

These, then, are the good new days, but sooner or later some lad is going to raise his voice loud and clear and tell us all that the cloth is full of holes and the Emperor looks mighty shoddy. I'm inclined to believe, in fact, that the voices are already being raised. Several first-rate students I have known recently have reacted very negatively to the University environment. No doubt that has something to do with their turning away from science or their search for teaching positions in small out-of-the-way colleges. If we want to weave whole cloth for the University, for Science, for the World in which we live, we'd better keep an ear to the ground for that young fellow who has the simple, direct honesty to tell us when the Emperor has no clothes on.

The Big Swindle—The World Environment

Last we come to the beautiful world around us, the planet Earth. Every one in this room knows what man has done to the good earth. Happily the journals, both technical and popular, and increasing numbers of books are setting the story before people who can read and are interested. Lamont Cole, "Can the world be saved?";" Kingsley Davis, "Population Policy, will current programs succeed?";20 Justice Douglas, "An Inquest on our Lakes and Rivers";2' the Paddocks, "Famine—1975!"22 Secretary Udall, "The Quiet Crisis""—these are but a few of the signs that mankind is beginning to be aware of the massive impact the human species has had upon the planet and the consequences that must be faced. I scarcely need to remind you of Lake Tahoe or Lake Erie, of Silent Spring or the fish kill in the Mississippi, or of the Governor (and erstwhile presidential aspirant!) who says of the great sequoias, "When you have seen one you've seen them all."

My own awareness has grown surely and deeply over the years as a few reminiscences will illustrate. As a mop-pet being brought up in the early 1920's in Manhattan, I often remarked upon the reddish haze that smarted my eyes and obscured the outline of the looming sky-scrapers.'' That, I was told, is "heat haze." What a euphemism! It was a long time later that I realized the heat haze of my childhood was the ugly mantle that would shroud Los Angeles and every major industrial and population center of the developed world. Then there was one of those moments, vividly recalled, when awaiting the change of a traffic signal on Park Avenue, my father, then nearing the end of a career as a physician and Professor of Public Health, deeply committed to protecting human life, turned to me, I thought sadly, and said, "Medicine has brought excessive population upon us; medicine must find some solution." At college I read with wonder and growing concern the first and perhaps most inspired of Paul Sears' volumes, "Deserts on the March, a book that should be required reading for every high school student through-out the world. It was thirty years thereafter that I sailed among the Greek Islands marvelling at their ancient history and the lives men led there 5000 years or more ago. At Knossos, where Sir Arthur Evans recreated the palace—to the dismay of pure archaeology but to my delight—I marked the strapping two-foot wooden beams replicated in brown cement. Where, I asked, were such great trees to be found? Pointing to the scarred, utterly barren slopes of the nearby hills, my informant spoke of forests of great cedars all around the eastern Mediterranean. First I imagined with joy what a glory it must have been, but then my mind's eye moved westward through the Mediterranean, the bare lands of Southern Italy, the dry bleak hills of Spain, even the green fields of jolly England, once covered with mighty oaks. Travelling swiftly I crossed the Atlantic, whipped through the scrubby woods of the eastern seaboard across our great land, and came at last to the redwood forests on the Pacific Coast. "When you've seen one you've seen them all!" That must be what some enterprising Greek admiral had said, some Roman general, some Spanish Don or English Lord (Fig. 6). Evidently, whatever anyone else might say, the progress of each of these great civilizations had depended to a major extent upon a deterioration of the natural environment. Was this the greatest of all swindles? Had the promoters, the developers, the advertisers, the leaders, the advocates of progress sold mankind a bill of goods? Was this whole cloth for the Emperor's new suit or was he marching down the street naked, afraid to recognize the truth?

The answer is not simple. I live in a wooden house, own a gasoline-burning car, fly to Washington ahead of a foul jet-stream, and reside in the world's richest agricultural area where crops are seeded and fertilized by air and sprayed with tons of pest-controlling chemicals. I enjoy all the benefits of civilization. Still, I wonder if it will prove worth it in the long run. I am inclined to believe that the Emperor is wearing little more than a new jockstrap and we should take a sharp look at the motives and principles of the people who are weaving the cloth.

If a man wants to get to the moon has anyone figured




the cost in terms of irreplaceable resources used and contamination of the environment, let alone the human energy and ingenuity desperately needed elsewhere? When wars are planned and fought, does anyone weigh in the balance the rape of the earth? In his documentary study of British Admiralty records, John Ramsbottom, one-time Keeper of Botany in the British Museum, came to the inescapable conclusion that it cost Britain all her forests to rule the waves for 300 years." No doubt the same was true for Greece and Rome and Spain in bygone days. Later, it was steel and coal and now it is oil and chemicals by the megaton and thousands of drums of radioactive waste hid-den away, out of sight out of mind. It is said that defense demands the testing of atomic bombs and the defoliation of vast areas of tropical forest. Tinbergen stated recently that "Man is the only species that is a mass murderer, the only misfit in his own society."' It must be added that he is the only species busily ruining his own environment and that his propensity for mass murder is one of the major factors in this ruination. Tinbergen also said, "It is an old cultural phenomenon that warriors are both brain-washed and bullied into all-out fighting."' Obviously brainwashing and bullying are not confined to the warriors. Are there any small boys about? We need to know whether the Emperor is in his birthday suit.

Man has sold his fellows another more subtle and very probably much more serious bill of goods. Ever since the very beginning, "Progress" has meant more people. For thousands of years society has encouraged itself to multiply whether for fighters, farmers, laborers, religious supporters, helpers in old age, or just plain John Q. Public with the consumer dollar. Perhaps agriculture was the first major step in the progression and, on the face of it, farming seems like a harmless and natural process. But it was soon overdone and cradles of civilization became desert wastes. Man moved on to new fields but now there is no place to go and there are all these people still encouraging themselves to multiply. By dint of agricultural and chemical technocracy that threatens the balance of nature as never before we are proudly extracting the ultimate calory, ingeniously making a bit more protein, talking big about making food in factories. But the chips are down, the game is up, there are too many people. Yet even today, with the world's population doubling every 30 years and rates of population increase rising even faster than the most extreme predictions, why are whole nations, whole religions, and whole societies opposed to birth control, often precisely where control is most obviously needed? Man's failure to recognize and act upon this problem may be his undoing, and this failure has to be chalked up to the biggest swindle, antiadaptation if you will, of all time. And this time a small boy won't do the job. We need a big man with a mighty voice to tell the world the Emperor is stark naked. For this purpose we need the very forces that have perpetrated the swindle. Consider what could be done by a world education campaign organized by American advertising, backed by the Russian propaganda mill, approved by the Vatican, and supported by the $100 billion a year that mankind puts into armaments and defense! Which means more to us, selling obsolete arms to Latin America or selling birth control? We've got to get that cloth woven and put some honest--to-god clothes on the Emperor's back. We must begin by recognizing and accepting a realistic appraisal of the present situation. Kingsley Davis and the Paddocks urge us to quit kidding ourselves and face up to the swindle. If men stop multiplying they might learn to stop fighting and then they might have time to discover how to adapt to their natural environment as well as the molds have done.


What we have been talking about is man's progress, whether he has been moving onward and upward or whether




his span on earth is more accurately depicted in Figure 7. Obviously Botany has a great deal to do with this, and it is up to us to see that man's efforts are not devoted exclusively to explosive chemistry (Fig. 8). I urge you, therefore, to cast your eyes upon the Emperor's New Clothes" s and ask yourselves again how we can weave whole cloth.

The week before this Congress there will be two other science meetings at which botanists may have an opportunity to present papers and participate in the sessions: the Pacific Division of the A.A.A.S. will meet at Washington State University, Pullman, and the A.I.B.S. will hold its sessions during this same period at the University of Vermont, Burlington.

The American Society of Horticultural Science (national organization), the Western Section of the American Society of Plant Physiologists, and the Pacific Section of the Botanical Society of America are among the groups that are planning sessions at the Pacific Division meetings in Pullman. A Pre-Congress Conference on Pollen and Pollen Physiology is also being organized. A.A.A.S. members in the area of the Pacific Division will soon receive copies of the Preliminary Program for these meetings; others may obtain copies by writing to Dr. Robert C. Miller, Secretary, Pacific Division, A.A.A.S., California Academy of Sciences, Golden Gate Park, San Francisco, California, 94118.

An A.I.B.S. Special Plant Science Session will be held as part of the A.I.B.S. annual meeting at the University of Vermont. Botanists who wish to present a paper are invited to send a title and an abstract (not to exceed 300 words) to the organizing committee: Plant Science Session, Marsh Life Sciences Building, University of Vermont, Burlington, Vermont 05401. Titles and abstracts must be mailed before April 1, 1969.

We note with regret the passing of two well-known emeritus botanists, formerly associated with the University of Michigan. Emeritus Professor Edwin B. Mains, former Director of the Herbarium, University of Michigan, died on December 23, 1968 at the age of 78. Emeritus Professor Felix G. Gustafson, discoverer of the induction of parthenocarpy through hormone treatment, died on January 13, 1969 at the age of 80.

Gatlinburg Wildflower Pilgrimage

The 19th Annual Wildflower Pilgrimage will be held in Gatlinburg, Tennessee and surrounding territory April 24-26, 1969. It is sponsored by the Botany Department of the University of Tennessee, the Great Smoky Mountains National Park, the Gatlinburg Chamber of Commerce, and the Gatlinburg Garden Club. Motorcades and trail hikes under expert leadership take you to areas where spring wildflowers grow in quantity and variety. Morning bird walks are a feature of each day's activities. Special programs are arranged for photographers, and there is an opportunity to show one's own slides.

Each evening there are illustrated lectures on features of the natural history of the Appalachians, a coffee social, and a plant identification clinic. Detailed descriptions of each Pilgrimage activity are furnished at the time of registration.

For further information, write Dept. W. P., Gatlin-burg Chamber of Commerce, Box 527, Gatlinburg, Tennesee 37738, or Dr. Edward E. C. Clebsch, Department of Botany, The University of Tennessee, Knoxville, Tennessee 37916.

Pre-Convention Conference 1970

Prior to the 1968 AIBS meetings in Columbus a pre-convention conference was held (September 1 and 2) sponsored jointly by AIBS and The Botanical Society of America, Education Committee.

The subject of that conference, "Morphogenesis of Plants," was chosen because of your letters responding to our request in the Plant Science Bulletin. The success of the conference has been expressed in several ways, among them a unanimous vote of those in attendance that another such conference be held in 1970 before the AIBS meetings.

This is an appeal to you, as a member of The Botanical Society of America, to make recommendations for a general theme, or particular subjects around which we can identify a theme, or particular speakers. In making these suggestions please bear in mind that the purpose of the conference is to update those among us who by reason of specialization or preoccupation with teaching have not kept abreast of all exciting frontiers in Botany and Biology. These frontiers will beckon undergraduate students into advanced work only when they are presented well by their instructors.

Our preliminary plans for the 1970 conference must
go to AIBS in June if they are to seek NSF funding for
us. Please send your suggestions as soon as possible to us.

Book Reviews

HULTEN, ERIC. Flora of Alaska and Neighboring Terri-

tories. A Manual of the Vascular Plants. Stanford

University Press, Stanford, California. 1968. 1008

pages. $35.00.

The dean of arctic floristicians and phytogeographers has produced in this incredible volume a lavish encore to his earlier oracle, "Flora of Alaska and Yukon" (1940-49). The new flora is a diagnostic manual designed for a larger public than the previous research flora, and as such it is more compact and includes keys to the families and genera as well as to the species. The more complete keys will please all users who have ever found themselves stymied


in the older work by the absence of keys to the genera. But, alas!, the size and the price are hardly calculated to make it either a field manual or a layman's handbook. It is likely to remain in the laboratory or herbarium, where, however, it will be indispensable to the student of Alaskan plants and, especially by virtue of the maps, to all arctic botanists. This is not only a model flora, incorporating an extraordinary amount of personal experience and insight, but also another of the outstanding contributions to arctic geobotany for which Professor Hultēn is so famous. No other living botanist is as con-versant on the arctic and boreal plants of the entire circumpolar realm from North America to Asia to Europe to Greenland. It would be hard to exaggerate the practical and theoretical influence of his studies on floristicians and phytogeographers. In this new volume we are presented with almost a lifetime of thoughts on the Alaskan flora, distilled into a fresh descriptive conspectus that succinctly reveals his taxonomic concepts.

The spacious page format sparkles with clarity. On the average, two species are treated per page, and the treatments are always contained on the same page, so that one need not turn elsewhere for a map or an illustration. Unfortunately, this very pleasing layout also wastes much space that could have been traded off for less bulk, making the book truly a field manual. Each species is featured with a short description, a line drawing or two, and two maps. Distribution in the territory of the Flora is shown in a dot map, and the other map depicts the circumpolar range in outline. The description may include a general habitat characterization. Discussion of biology, taxonomy, or nomenclature is kept to an absolute minimum; the book is purely an identification manual. Taxonomic and nomenclatural changes are presented in an earlier paper (Arkiv for Botanik 7: 1-147, 1967), where Professor Hultēn can prove a little hard to convince with detailed biosystematic evidence. Thus, thorough investigations like that of Argus on the Salix glauca complex are waved aside, and one has the impression that sometimes Hultēn is trapped by his own fruitful but seemingly a priori historical arguments. To those who find him subspecies-happy it should be pointed out that he has provided taxonomists with a dynamic, geographical point of view that serves to set up numerous hypotheses for intensive investigation by others. Above all, Hultēns new Flora will help enormously to stabilize the names of arctic plants. He has picked his way through prolific Russian splitting to emerge as before with a moderate species concept.

The book includes a valuable introduction, covering ecological, geographical, and historical aspects of the flora, and closes with an extensive glossary, list of authors, and bibliography. The middle of the book is graced by eight pages of spectacular color photographs of plants and places. The book is a triumph by any standards and certainly a new milestone in the floristic literature of North America. The Stanford University Press is to be congratulated for its technical production, and special mention is due Dr. John Hunter Thomas for editorial work.

pects of Nitrogen Metabolism in Plants. (First Long

Ashton Symposium, 1967) Academic Press, New York.

1968. 280 pages. $11.50.

This selection of papers is the outcome of a symposium
held at the University of Bristol in April, 1967. All of
the 88 participants were from the British Isles. The 14
papers were presented in three sections: "Transformations
in inorganic nitrogen metabolism and fixation"—E. W.
Yemm, Chairman; `Intermediate metabolism of amino
acids and relationships with mineral nutrition and protein
synthesis"—F. R. Whatley, Chairman; and "Interaction of
nitrogen metabolism with external factors"—O. V. S.
Heath, Chairman. Discussions were held following each
section, and E. W. Yemm gave an excellent summary at
the close of the symposium, especially directed toward the
importance of respiratory and photosynthetic processes in
nitrate assimilation and in biosynthesis of amino acids
and proteins. Although there is a slight unevenness in the
papers in topicality and depth of treatment, the overall
quality is excellent. The "recent" denotation in the title
is a valid measure of the references of which the great
majority were published within the past four or five years.

REINHOLD, L. AND Y. LIWSCHITZ, editors. Progress in Phytochemistry, Volume 1. Interscience Publishers, New York, 1968. 723 pages. $23.75.

This volume contains eleven chapters entitled as follows: Acyl Lipids and Fatty Acids of Photosynthetic Tissue; Chemistry of Plant Cuticles; Relationship between Plant Growth Hormones and Nucleic Acid Metabolism; Recent Advances in the Chemistry of the Tetracyclic Diterpenes; Biosynthesis of the Gibberellins; Lichen Substances; Biochemistry and Physiology of Phytochrome; Biochemistry and Postulated Mechanisms of Nitrogen Fixation; The Tropane Alkaloids; Biochemical Systematics; Constituents of Ferns.

Each chapter, authored by an expert (s) in the field, admirably conforms to the two-fold intention of the series, to wit: (1) to present sufficient background in-formation to give the non-expert a comprehensive view of the subject matter; (2) to provide the expert with recent advances in the field.

Several of the chapters will be of great utility to the
plant physiologist, since their counterparts do not exist
elsewhere. This reviewer, for one, is looking forward
with great anticipation to future volumes in this series.

DARLINGTON, ARNOLD. The Pocket Encyclopaedia of Plant Galls in Colour. Philosophical Library, New York. 1968. 191 pages. $7.50.

Three short introductory chapters, entitled, "Galls: Their Cause and Variety," "Gall Occupants and How they Live," and "Practical Work," occupy only 30 pages. On the next 80 pages are 293 excellent colored illustrations of galls and the main types of animals that colonize them. A few fungus-induced galls are also shown. The remaining pages of the text provide an annotated listing of representative British host plants and their galls, followed by an index to common and scientific names of gall occupants and host plants.   Adolph Hecht
