University of Wisconsin Press, 1930 Monroe Street, Madison, Wisconsin 53711; ISBN 0-299-21054-5; xx + 215 pages; paperback, $26.95; ISBN 0-299 -21050-2, cloth, $60.00. The intended coverage of this fine new book is nearly that of our journal, east to Ohio, and including also Iowa and Missouri. The cover photograph (on the paperback version at hand) shows a solid understory of garlic mustard, Alliaria petiolata (Brassicaceae) in a woodland. There is no caption for the photograph (and the photo is not repeated inside), but the author and her book designer surely deemed one unnecessary-this has become an all-too-familiar sight in this part of the world. That invasive species have a large economic impact may not be self-evident, and for that reason, the point is made repeatedly throughout the text. There are also deleterious effects on wildlife: degradation of grazing areas for elk further west; monarch butterflies adversely affected by ovipositing on swallow-wort (Vincetoxicum, Asclepiadaceae), though no literature citation is given; and some fascinating interactions between birds and weedy Lonicera as given on page 32. One of the most useful features of the book is the extended treatment of various herbicides that are available. Application methods are also given in considerable detail. (Alas, all the wasted hours spent spraying diluted Roundup on the leaves of buckthorn! This book tells you how to do it, and do it right.) The subject of how long seeds of various species may survive in the soil is repeatedly mentioned. It's a common notion that the troublesome invaders in many ecosystems are all introductions from the Old World. The author does not fall into this error, and devotes an entire chapter to native plants that sometimes need control. There is a very ample index. But indexers always make decisions, and sometimes the results can be troubling. For example, the monarch butterfly didn't make it into the index (not listed under "butterflies," either), so that you can't readily get back to the story referred to above. It's on page 132. There are some minor misspellings, like Cirsium miticum (for muticum), but they won't trouble anyone. There are no keys. That would not have been practical in a book of this nature. The color photographs and lengthy descriptions will suffice for nearly all users. There are, according to the blurb on the UW Press website, 262 color photographs and 20 drawings. One regrets that the author (b. 1950- d. 2003) did not live to see her fine book in print. The work is a most fitting memorial. --Neil A.
