"This revised edition of the popular field guide provides a color photograph and gives family name, scientific name, common name, and a general description for each of more than 180 species of trees, shrubs, and subshrubs and more than twenty species of cactus common to the fourteen southernmost counties of Texas. The book contains 12 species not included in the previous edition, plus newly updated information. It describes frequently encountered species as well as many rare or endangered species, and native plants as well as introduced plants that have escaped cultivation and are reproducing in the wild." "This publication will be useful to ranchers and ranch managers, scientists, and anyone else interested in the flora of southern Texas. Information gleaned from this book will contribute to sound land management programs."--BOOK JACKET.
