Indiana University Press, Bloomington. Paperback; 358 pp. ISBN 0-253-21420-3 $17.95 Most amateur botanists are accustomed to the various field guides available for learning plant names for a particular state or region. Many of these guides have the plant species arranged in an artificial way by flower color and/or shape of the corolla and a color photograph of that species. The bright red paper cover of this field guide is an indication that this book is different from all the rest covering the Great Lakes region. Most field guides are usually purposely incomplete in the species covered. 40% or more of the wildflowers of Indiana are not observed in available field guides. This book discusses all 1,564 herbaceous species known for the state (excluding grasses, rushes, and sedges). There are 640 color photographs with at least one photo image for each visually similar group or genus. The discussion of each species includes Latin name with author names, family, common name, and general description of the species, soils and ecology, habitat, distribution within Indiana, blooming time, plant size, the flowers and the inflorescence. Because Indiana is a state where four or five different written floras overlap in their coverage, and different Latin names may have been used, the author has placed these names in brackets for cross reference. There is also a brief discussion about the similarity and differences betweeen species. Species are noted as being native, introduced into the state, and those that are Endangered, Threatened, or Rare, Extirpated, or on a Watch List within the state. Some species have line drawings showing features that help in proper identification. The species within the book are grouped by families with the families following a modified classification system similar to one proposed some years ago by Arthur Cronquist. The book begins with (1) Saururus cernuus, in the Saururaceae and ends with (1564) Isotria verticillata in the Orchidaceae. To get all the species listed with discussion in a book of only 358 pages, four to six species are grouped to a page. To identify the species, the user must follow a Flower Finder. This finder is divided into eight parts where the unknown is compared to illustrations within each group. For example, Group A is corolla 2-lipped. The unknown flower is

Page  18 ï~~18 THE MICHIGAN BOTANIST Vol. 41 compared with ten different sketches of 2-lipped corollas, then going to that part of the species listing of the guide and comparing those species which are most similar to it. One hopes that, with practice, the individual will be successful. Because 60% of the wildflowers listed lack sketches or photo images, this will take considerable practice on the user's part. Another difficulty comes with some groups having a long list of exceptions. For example, Group D, Flowers with petaloids numbering 5 has a two-column, half-page list of other examples to consider. This I can see could be very discouraging to all but the most determined amateur botanist. The photographs are small but of good quality and illustrate the necessary features to properly identify most species. It is too bad more images were not used as this may discourage some amateur botanists from using the book. There is a seven page word Glossary that is fairly complete for the terms used in the book. A single page labeled sketches of the parts of a flower and a labeled composite head inflorescence follows the glossary. This seems a bit lacking to this reviewer as there can be some very complex heads other than those found in the Aster family and corymbs, cymes, and panicles that need interpreting. A 37 page Index is most helpful when looking up species when the user already knows the identity of the plant. Only the genus Rosa was observed to be lacking. Will this book replace the use of the more easy to use color-coded, thumbthrough, color picture field guide used today by many an amateur botanist? Yes, for those wanting a guide only for Indiana. No, for those unwilling to put forth the time to identify completely one of the various Potentilla (cinquefoil) species, for example. However, Yatskievych is to be commended for her attempt to bring the American public to a higher level of botanical knowledge and scholarship. Time will tell if she is successful. - Dennis W.
