Page  78 ï~~78 THE MICHIGAN BOTANIST Vol. 44 REVIEW Welsh, Stanley L., N. Duane Atwood, Sherel Goodrich, and Larry C. Higgins. A Utah Flora, third edition, revised. 2003 (post 15 April 2003, the date on the preface.) Monte L. Bean Life Science Museum, Brigham Young University, Provo, Utah 84602; available at the museum, credit-card orders by telephone at 801. 422. 5052; $85 postpaid. Hardcover, xxii + 912 pages + endpaper map after p. 912. ISBN 0-8425-2556-4. The first edition of this work appeared in 1987; the second edition appeared in 1993; and now we have the third edition. I am unaware of any announcement of the appearance of this book. It does not appear at amazon.com. This edition continues all the tradition established in the two earlier editionsclearly written keys, ample descriptions, warning notes about taxonomic difficulties, and unambiguous citations of range within Utah, as well as elsewhere. In this third edition, the complete citations for places of publication of names are given; nomenclatural types are often cited, and earliest date of collection in Utah is given for many adventives. The book is printed on larger paper, so that the thickness of the third edition is less than that of the second edition. It breaks with tradition by incorporating a goodly number of nomenclatural innovations, summarized on pp. 838-840. New species and new combinations are made throughout the text. Four new species are given fully only in these summary pages because they are extra-limital-all from McKinley County, New Mexico, well south of the Utah border. They are included here because the holotypes are deposited at BRY. One of these four is invalidly published because it does not include a Latin diagnosis or description. In order to correct this oversight, we have: Welsh, Stanley L. 11 May 2005. Correction to an effectively but non-validly published species of Astragalus (Leguminosae) from New Mexico. Rhodora 107(#929): 103-104. That paper begins, "On page page 839 of A Utah Flora, ed. 3 (October 1993; Monte L. Bean Life Science Museum, Brigham Young University, Provo, Utah), a name was effectively but not validly published, due to inadvertent lack of a Latin diagnosis." And that's how I found out that a third edition of 2003 existed, when I tried to unravel this mixture of duplicate words, edition number [correct], publication date [incorrect], and page number [correct]. This fine book certainly has a place in a professional library. Moreover, it is a goldmine of stray information for the interested amateur ("lover," in every best sense of that word). The authors include, with keys and descriptions, the major cultivated plants of Utah. I hadn't realized that, in order to have a truly arborescent oak tree in your yard or in a park in Utah, you have to import one from the eastern US and Canada or even Europe: white oak, swamp white oak, bur oak, northern red oak, and English oak. - Neil A.
