Page  377 ï~~2004 THE MICHIGAN BOTANIST 377 (pollen analysis). Here are the best illustrations of the entire book and also some color to emphasize points made about the stages of meiosis and mitosis. The micrographs of light and scanning electron microscopy (SEM) of pollen are superb and certainly give the reader an understanding of pollen features helpful in identification to plant species. It ends with some interesting case studies. The final Chapter 15 looks to the future of forensic botany and where DNA typing technologies of plants might lead, especially forensic plant genotyping. Each chapter has a selected list of references at the end. There are four appendices: Appendix A: Considerations for the Use of Forensic Botanical Evidence: An Overview; Appendix B: Glossary of Terms (covers nine pages); Appendix C: Directory of Contacts (may be helpful to those involved in forensics); and Appendix D mentioned above. The book is small in size at 6 x 9" (16 x 25 cm), printed on acid-free paper, and with some figures and photographs in most chapters. Except for the outstanding ones mentioned above, most photos are on the dark side and of poor quality. At a price of $100+ the book will have limited personal sales. On the positive side, it does give the enquiring person an introduction to forensic botany. The varied case studies given between its covers may make the book of value to most college or municipal libraries. Dennis W.

Deam and Floyd A. Swink. 1946-1951. Shirley Heinze Environmental Fund, 444 Barker Road, Michigan City, IN 46304, 387 pp. ISBN 0 -7388-2572-7 (Softbound), $18.00 (http://www.heinzetrust.org/). The two central figures of this book are amateur botanists who contributed greatly to the understanding of wild plants in the Great Lakes area. Charles C. Deam, who wrote, in the opinion of the late Dr. Richard Pohl of Iowa State University, "one of the best state floras," the Flora of Indiana in 1940, and Floyd A. Swink co-author of Flora of the Chicago Region, 4th edition, with Gerald Wilhelm, 1994. These two heroes of Indiana plants laid the groundwork for the rest of us to build upon. These letters allow us to peer into the minds and to follow the collecting trips of two giants of 20th century natural history in northwest Indiana. They also provide a glimpse into the life and times of these two very interesting, dedicated botanists. Peg Mohar edited this compilation of the letters and notes that passed between these men, largely after Deam retired, and at the beginning of Swink's ac

The information comes from typed, double-sided copies in Swink's files, which he was most willing to share, help edit, and contribute to right up until his death, at age 79 on 2 August 2000. The letters began on 5 January 1947 when Deam was 81 and continued until 1951, two years before his death. Some are lengthy and deal with observations about northwest Indiana plants where both authors use Latin names in their discussions. This certainly reflected their botanical understanding, that a "common name" was an inferior way to properly communicate scientific information. At the end of each letter, footnotes have been added to better explain the content. There are only seven pictures in the book. Two noteworthy photographs show Deam sitting and eating breakfast in the field by his "weed wagon," and Swink standing by Senator Paul Douglas, who along with Swink was helpful in getting the Indiana dunes preserved and set aside as a National Lake Shore. The ten page Introduction by Barbara Plampin gives the background and history of these two men, and it is a must to fully understand the meaning of the letters in the Letters chapter, which takes up pages 25-342. A short three page (343-345) Afterword, gives some of the testimonials spoken at the memorial service for Floyd Swink on 7 August 2000. Two Indexes are provided at the end: a Plant Index, which gives common and Latin names of plants mentioned in the text; and a General Index with all the names of individuals, localities, and geographical regions mentioned in the letters. A fold out map of the "South Lake Michigan Region-1950" is attached within the back cover. Those interested in the history of botanizing during the mid-twentieth century will find this an interesting book to read. Dennis W.
