In this reprint of the 1973 original by Brigham Young U. Press, Flowers (U. of Utah) examines 256 species in 77 genera and 18 families among the bryophytes of his native country, many of which he discovered. In this labor of love that took decades, he describes the morphology, ecology and distribution, and methods of studying the mosses of Utah, including how to collect them and create an herbarium. His catalog includes detailed descriptions, many including illustrations, the derivation of names, environment, locale, and typical location in Utah. He also includes a map and glossary, and a new preface has been added. Annotation 2005 Book News, Inc., Portland, OR (booknews.com)
