The following two articles have a common theme relating to the image and vitality of the Botanical Society of America. I am confident that within our membership there are both supportive and differing points of view on either or both of these topics. I encourage your thoughtful response to these timely issues that face our discipline and our society.

WHAT'S IN A NAME?

During this year's Council meeting, two perennial problems were discussed once again: declining membership in the Society and a lack of broad representation of section topics in the Journal. Of course, over the years these problems have been due in part to the creation of separate societies to represent the ecologists, mycologists, phycologists, physiologists, and taxonomists. During this year's discussion, it occurred to me that our position has continued to decline in more recent years--despite the valiant efforts of our Member-ship and Appraisal Committee--because of the changing concept of what is encompassed in the terms "botanical," as in Botanical Society of America and "botany," as in American Journal of Botany. During the past 25 years especially, the concept of "botany" and of things "botanical" has gradually changed from a very broad one to a relatively narrow one. When the Society was founded, the concept of "botany" encompassed all aspects of biology dealing with plants and the Society was the umbrella society for those interested in basic education and research on plants. Unfortunately, the concept of botany held today by most young, aspiring biologists, by most of our contemporaries, and by funding agencies and university administrators seems to date back to the late 50's or early 60's, and does not include modern molecular, cellular, genetic, and developmental aspects. In fact, to many people today, "botany" has a distinct, archaic odor.

What can be done about our problems of declining membership and lack of broad representation in the Journal? I believe a positive step would be to adopt a new name for our Society, a name that today conceptually encompasses all aspects of our science. I propose that we change the name of our Society to the American Society of Plant Biology (Botanical Society of America) and that of our Journal to the American Journal of Plant Biology (American Journal of Botany).

The previous Society and Journal names would accompany the new names in parentheses for five or more years to ease the transition. (They could accompany the new names indefinitely.)

With the exception of those enrolled in colleges of agriculture, most undergraduates interested in plants today are graduating from biology departments, not from botany departments. They do not regard themselves as botanists but as biologists and, apparently, most favor enrolling in biology or plant biology departments for graduate degrees. Check with any of the still existing botany departments about the increasingly difficult problems they are experiencing in recruiting top-flight graduate students. I contend that a change in the name of those departments from botany to plant biology would make a significant difference. Few molecular biologists working on plant material would consider joining the Botanical Society of America or publishing in the American Journal of Botany. But how about the American Society of Plant Biology and the American Journal of plant Biology?

The suggestion of a name change was made at the Council meeting this summer. Much to my surprise it received a very positive response, and I was encouraged by the

1

Council to write this letter. Before I left Toronto for home, one of our Society members told me that he wished I had made such a suggestion 15 years ago. He was certain that had his department become a "Plant Biology Department," an impending merger with two or more other departments on his campus could have been avoided. Others said they always ally themselves with members of one or more other departments in order to improve their chances for financial support from their universities. To apply under "Botany" was to guarantee failure. They feel "Plant Biology" would make a difference. Unfortunately, much of the problem lies in the name Botany.

Not all of the response at Toronto was positive. To some it seems disloyal to change our name. We should "educate" people about "botany." Many of us have been trying to do so all of our professional lives. (Incidentally, Webster defines botany as "a branch of biology dealing with plant life.") The problem with "plant science" is that it already has strong implications for the agricultural sciences horticulture, agronomy, and plant pathology.

I have tried to compile a list of the negative consequences that might result from a change in the name of our Society to the American Society of Plant Biology. I have failed to identify any negative consequence. I believe, however, that we may miss a golden opportunity to seize the initiative--to enter the 21st century with a new image and with renewed vitality.

A botanist by any other name is still a botanist. I will always identify myself as a botanist. At the same time, I think it is imperative to do everything possible to make our profession as appealing as possible to a broad spectrum of individuals working with plants and plant material. As corporations and individuals change their names for conceptual purposes or to present a new image, professional societies should not hesitate to do so.

BOTANY DEPARTMENTS VS. BIOLOGY DEPARTMENTS: Is There a Difference for Botanical Society of America Members?

Introduction - In 1913 W.G. Farlow ex-pressed the fear that biology departments were a way to decrease the employment of botanists (Farlow, 1913). As an undergraduate and graduate student in strong botany departments, I heard this same concern voiced in the 1970's. As a faculty member in the 1980's, I have watched as my retiring botanical colleagues in the "School of Biological Sciences" were replaced by molecular zoologists and I became curious to see if this trend was national and if it could be documented.

Materials and Methods - Data on employment of botanists (defined as membership in the Botanical Society of America [BSA]) for fifty years was obtained from the 1938-1939 and 1952-1954 BSA Year Books and the 1977 and 1988 BSA Directories. The geographical index of members was used in the 1938-1939 Year Book and each college or university with two or more members was included in the sample for that interval (non-academic institutions were excluded). For the 1952-1954 Year Book and the 1977 and 1988 Directories, colleges and universities with more than five BSA members were included. For the 1988 Directory, which lists members by geographical rather than institutional localities, the list of members was checked against the names and addresses if there was more than one college or university in the city. For each institution two or more names were checked to determine if that college or university had a biology or a botany department; plant science and combination botany/microbiology or botany/plant pathology departments were counted as botany departments.

Three categories of affiliation were used: botany departments that remained botany departments, biology departments that remained biology departments, and botany departments that switched to biology departments at some time between 1939 and 1988. The number of BSA members for each department was totalled for each of the four times and the net changes in membership for 1939-1954, 1954-1977, 1977-1988 were counted. (Due to the tedium involved, the counts were not double checked so there are probably some minor errors in the sums.) The BSA membership total for each of these four sample years was also recorded and the changes in the total membership for each interval were calculated as were the average largest number of members and the change in membership from the largest size to 1988.

The net changes were averaged for the three categories as well as a fourth category, departments that switched to biology in that particular interval. The averages were compared used a t-test to see if the differences were statistically significant.

Results - The results provide some support for Farlow's suspicions. For all intervals the increase in the number of BSA members was greatest for botany departments although the differences between botany departments and each of the other categories are statistically significant only for the 1954-1977 time span (Table 1).

TABLE 1. Average Changes in Number of BSA Members by Type of Department at Academic Institutions

Years	Botany Depts.	Biol. Depts.	All Depts. Switch	Depts Switch This Time
'39-'54	+6.06	+1.86	+2.82	+0.50
'54-'77	+4.54	-3.82*	-1.89**	-3.67**
'77-'88	+1.18	-0.28	-0.75	-2.00

* Difference significant at the 95% level ** Difference significant at the 99% level

Botany departments had the largest aver-age number of members at the peak of BSA membership (Table 2). The change from the largest size to 1988 was similar for the three categories so that proportionally botany departments lost fewer members.

TABLE 2. Largest Average Institutional Membership Totals and Average Change from High to 1988

	Average Largest Size	Change from Largest to 1988
Botany Depts.	19.98	-3.00
Biology Depts.	10.10	-3.69
Depts. Switching	11.89	-2.96

The BSA membership increased by 852 members (70%) from 1939 to 1954 and by 1255 members (61%) from 1954 to 1977. From 1977 to 1988, the number of members dropped by 567 (17%) (Table 3).

TABLE 3. Changes in Botanical Society of America Membership Changes in

	Changes in Number of Members	Changes in %
1939-1954	+852	+70%
1954-1977	+1255	+61%
1977-1988	-567	-17%

Conclusions - Plant scientists' self-identifications as botanists (as demonstrated by membership in the BSA) appear to be strongest at academic institutions that have botany or plant science departments. The switch from botany departments to biology departments may have a serious impact on future BSA membership unless plant scientists in biology departments can be convinced that membership in the BSA is of value.

ANNOUNCEMENTS

Young Botanist Recognition Awards

The Botanical Society of America requests nominations for the Young Botanist Recognition Awards for 1990. The purpose of these awards is to offer individual recognition to outstanding graduating seniors in the plant sciences and to encourage their participation in the Botanical Society of America. Award winners each receive a Certificate of Recognition signed by the President of the Society and forwarded to the nominating faculty member for presentation.

Nominations should document the student's qualifications for the award and be accompanied by one or more letters of recommendation. Nominations should be sent to the Secretary, Gregory J. Anderson, Department of Ecology and Evolutionary Biology, 75 North Eagleville Rd., The University of Connecticut, Storrs, CT 06269-3043 by April 1, 1990.

Workshop on Tropical Families for Systematics Instructors

With the destruction of tropical plant communities, it is imperative that, as instructors of undergraduate systematic courses, we should introduce students to the important tropical spermatophyte families and pique their interest in research on the systematics, ecology, and conservation of these plants. These families often are not covered due to the lack of time, lack of adequate materials, or lack of familiarity on the part of the instructor. For these reasons, Fairchild Tropical Garden is offering a two-week workshop (May 20-June 2, 1990) on the systematics of the major tropical plant families to help established faculty members overcome some of these problems. The workshop will include short lectures on each of the families, collecting forays in the living collection, laboratory observation of material, and field trips to the Florida Keys and the Everglades. Participants are encouraged to collect her-barium and pickled material and to take photographs of material for use in their own classes. Participants will be housed at the University of Miami for a modest fee of about $185 (double) to $275 (single) unless they stay in a motel of their own choice. Tuition will be about $350. Enrollment will be limited to twelve. Further information and application forms may be obtained by contacting: Dr. Roger W. Sanders, Fairchild Tropical Garden, 11935 Old Cutler Road, Miami, FL 33156 (305/665-2844).

Scholarships in Tropical Biology

The Garden Club of America is offering two $5,000 awards to assist with field work in the area of tropical botany. Awards will be made on a competitive basis to graduate students conducting field work in the tropics as part of their doctoral dissertation research. The awards will be made on a one-time basis, and applications are due by December 31, 1989. Recipients will be announced by March 15, 1990. There is no application form, however, students must include the following: 1) a curriculum vitae, including graduate and undergraduate transcripts; 2) evidence of foreign language capability; 3) a two-page outline of the proposed research; 4) a letter stating his or her plans for the future (a long-term commitment to conservation of tropical forests and an intent to work in the area will add merit to the application); and 5) a letter of recommendation from the advisor, which should include an evaluation of the student's progress to date. U.S. citizen-ship is not a requirement, however, students must be enrolled in a U.S. university to be eligible for this scholarship. Please mail applications to: Jane McKnight, World Wild-life Fund/Garden Club of America, Scholar-ships in Tropical Botany, World Wildlife Fund, 1250 24th St. NW, Washington, DC 20037 (202/293-4800).

BOOK REVIEW

Crang, Richard and Karen Klomparens, eds. Artifacts in Biological Electron Microscopy. Plenum Press, NY, 1988. 233 pp.

At each step of specimen preparation for electron microscopy (EN), artifacts can be introduced. Recognizing these artifacts and knowing how to reduce or eliminate them are very important skills for every electron microscopist. This book provides a systematic treatment of the many types of EM artifacts, and I recommend it to new and more experienced workers who use the electron microscope.

This book is edited by Crang and Klomparens and contains eleven chapters written by specialists. Most of the topics relate to transmission electron microscopy (TEM) of ultrathin sections, although there are separate chapters on artifacts in scanning electron microscope (SEM) operation and SEM specimen preparation (and references to some SEM artifacts in other sections). There are chapters on artifacts encountered in the following steps of TEM: sampling, fixation, dehydration and embedding, ultrathin sectioning, staining, TEM operation, and photography. The final two chapters of the book are about artifacts in cryoelectron micros-copy and in analytical EM.

The book is very well-illustrated and will be useful as a practical guide. Each chapter contains numerous excellent photo-graphs of the artifacts that are considered. Some artifacts are more subtle (e.g., "pepper"-type lead precipitate near certain membranes), and even these are well documented.

I particularly enjoyed the chapter about artifacts in sampling specimens for EM and the chapter about photographic and interpretive artifacts. Both of these chapters discuss phenomena that many would not immediately think of as artifacts. Sampling artifacts refer to erroneous conclusions drawn from an inadequate sample size. An example of an extreme case is someone who makes generalizations about a particular structure based on repeated sectioning of one or two specimen blocks. The chapter on sampling artifacts makes the reader aware of sampling parameters and related factors that should be carefully considered. This chap-ter gives several examples of how large a sample size should be for particular specimens.

In order to be a good electron microscopist, one should be a good photographer as well. The chapter on photographic artifacts provides insights into the important (and often neglected) last steps of EM, i.e., producing high-quality photographs of the results. This chapter is particularly well-illustrated. For example, the author compares a TEM micrograph printed with diffuse illumination from an enlarger to a micro-graph printed with point-source illumination to illustrate the superior qualities of a point source. Another interesting discussion in this chapter concerns the methods to overcome the "noise" that is characteristically associated with electron exposure. Other topics include latent image instability, problems in print making, compensating for artifacts in negatives and prints, and interpretation of shadows in freeze-fracture micrographs.

My major criticism of this book is the limited discussion of some current topics in EM. Although embedding in epoxy resins is thoroughly treated, there is little discussion of embedding media such as Lowicryl or LR White resins which are being used increasingly in many labs. Other examples of topics not adequately considered are immunoelectron microscopy and freeze-substitution. Further discussion of these and some other topics may have increased the length of the book, but it would have made it more timely as well.

Since plant specimens are particularly difficult to process for EM, they may have specific artifacts associated with them. While there is brief mention of a few of these problems, more discussion would have been desirable for the botanical reader. Despite these limitations, I recommend this well-illustrated, compact book. New workers and students will learn from the excellent photographs which give examples of EM artifacts, and more experienced workers will find it a useful reference text.
