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. A.
