Page  118 ï~~118 THE MICHIGAN BOTANIST Vol. 44 REVIEW Adams, Robert P. Junipers of the World: The genus Juniperus. 2004. Trafford Publishing Company, Vancouver, British Columbia, Canada; ISBN 1-4120-4250 -X. vi + 275 pp. Softcover, U.S.$39.95, C$50.00. In order to purchase this book, you must go to the publisher's website, and charge it against a credit card. The book is then published on demand, and your credit card is charged for the book plus shipping and handling. Presumably, the book exists on a CD. One of the features this company offers is the possibility of altering and correcting the book-that could conceivably mean that your copy of the book will differ from mine. So far as I can tell, there are no nomenclatural novelties in the book, but you can well imagine the difficulties that could arise when one cites a [potentially] continuously changing book. The opening line of the book is an intriguing one: "Juniperus is the second most diverse genus of the conifers." The reader waits, so to speak, for the other shoe to fall, but it never does. At a guess, I'd say the author's intention was to add "... after Pinus." The keys begin on page 53. That's what most people are going to want to turn to. For convenience, the author has divided the keys up into geographic segments, which is a great help to the reader. Thereafter, the treatment of each of the 67 species is alphabetical. There is a very full synonymy given for each taxon, and an ample description, together with one or more photographs. In Appendix IV, we have "Seed cones and leaves in color." The pictures are likewise arranged alphabetically. Appendix II is a cross-indexed synonymy of Juniperus; that is to say, a nomenclator. This promises to be of great use to herbarium curators especially. There is a difficulty in the Literature Cited. Professor Adams cites about 75 papers of which he is the first author and sometimes the sole author. But they're not in chronological order. Hence, "Adams 1989" could show up just about anywhere. There's a citation of "Adams et al. 2003" on page 10. I cannot for the life of me be sure what the reference is, though I think it is to the second entry on page 216; in fact, there are four different papers that could be "Adams et al. 2003." Then on page 11, there's a reference to "Adams 2003," and so far as I could discover there is no such single-authored paper for 2003. From the context, I infer he meant "Adams et al. 2003," but that still leaves me four possible references. One doesn't need this book to identify the species of Juniperus around the Great Lakes. But if your net is cast a bit wider, then I think the book will prove to be invaluable. It does allow you to see your local populations of various juniper species in a broader context. We are fortunate that the author's worldwide experience with junipers is here in one place, and at a very fair price. There is no index, so if you want to return to the story about how the Gyrfalcon (Falco rusticolus) might be involved in the post-glacial plant colonization of Greenland from Iceland, you might want to write the page reference inside the covers. - Neil A.
