A Southwest Book of the Year * 2005 Southwest Book Award "[A] monumental study." --Review of Texas Books "A reliable and handy general reference for those with an interest in cacti inside and outside this region. Recommended." --Choice "These authors have . . . provided the world with the much needed scientific clarification on this family of succulent plants that humans have loved and hated for thousands of years." --Sida "Information: Wow! . . . For both lay readers and for researchers looking for lots of data about the cacti of this rich flora, this book offers fascinating details presented in a very readable fashion." --Cactus and Succulents Journal "This will be the standard reference for decades to come."--Southwest Books of the Year Of the 132 species and varieties of cacti in Texas, about 104 of them occur in the fifteen counties of the Trans-Pecos region. This volume includes full descriptions of those many genera, species, and varieties of cacti, with sixty-four maps showing the distribution of each species in the region. The descriptions follow the latest findings of cactus researchers worldwide and include scientific names; common names; identifying characters based on vegetative habit, flowers, fruit, and seeds; identification of flowerless specimens; and phenology and biosystematics. The introduction--full of details about the biology and morphology of the family Cactaceae, the uses of cacti, and the horticulture and conservation of cacti--is an important reference for general readers. More than three hundred beautiful full-color photographs of the cacti in flower and in fruit, all cross-referenced to their description in the text, highlight the book. A glossary of cactus terms, an exhaustive list of literature, and a thorough index complete the book.
