From reviews of the first edition: "A complete and professional treatment of the woody plants west of the Pecos River in Texas.... The manual is quite comprehensive and includes many slightly woody perennial herbs in addition to trees and shrubs....[It is] a valuable addition to the growing body of regional floras and will be a useful tool for all those interested in this beautiful and fascinating area." —MadroÑo "Dr. A. Michael Powell"s 25 years of botanical experience are evident in this work for both professional and amateur botanists. It makes easy the identification of 453 species of woody plants." —Wildflower First published by the Big Bend Natural History Association in 1988 as Trees & Shrubs of Trans-Pecos Texas, this book is the only keyed guide to the more than 400 species of woody plants native to the Trans-Pecos region and adjacent areas in eastern New Mexico and northern Mexico. A. Michael Powell has significantly revised and expanded this edition, including nomenclature changes for 62 genera and new distribution information for60 genera.
