The Cactus Primer presents the amateur cactophile with an excellent introduction to cactus biology and provides the informed reader with an invaluable summary of the last forty years' research. This book goes far beyond books that instruct readers in the propagation, growth, and care of these plants; addressing matters of more scientific interest, it takes an integrated approach to the presentation of the form, physiology, evolution, and ecology of cacti. The book is unique in that it combines the descriptive morphology and physiology documented in the scientific literature with more general observations found in popular publications on cacti. It provides a new generic classification of the cacti and contains much new information, including data on photosynthesis, heat and cold tolerance, computer modeling of ribs, and the effects of spines. Enhanced by over 400 illustrations and supplemented with an extensive glossary, this book will appeal to cactus enthusiasts interested in the classification and growth of cacti, as well as to plant biologists who use cacti to illustrate desert adaptation and convergent evolution. Written in accessible style, The Cactus Primer is bound to serve a dual function as both an instructive tool and a reference work in cactus biology for years to come.
Found in a variety of forms, cacti and other succulents have elicited widespread interest and tremendous popularity worldwide. Although the subject of a certain amount of debate, about 10,000 species are recognized as belonging to the succulent group. Of these, an estimated 2,000 are threatened with global extinction in the wild and many more are regionally or nationally threatened mainly due to habitat destruction and collection for international trade.This Action Plan brings together from around the world current information on population status, threats and conservation of this particularly important group of plants. Prepared with conservationists, scientists, governments, protected area managers and grant-awarding bodies in mind, it suggests priorities for action and encourages collaboration among interested parties at all levels.
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.
There are many reasons to grow cacti and other succulents—they're drought-tolerant, low-maintenance, and they look great. But what about hardiness? For those who thought that these spectacular plants were only for gardens in California and the Southwest, guess again—hundreds are fully cold-hardy and can be grown outdoors from New England to British Columbia, Wisconsin to Texas. Cacti and Succulents for Cold Climates is filled with inspirational portraits of 274 plants that can be used to create drought-tolerant gardens, as well as tips from regional experts who have mastered the art of growing cacti in parts of the country not usually associated with high temperatures or a scarcity of water. Expert Leo Chance describes how to prepare planting beds, how to get plants well established, how to handle cacti during planting, how to protect plants from cold winters, and when and how much to water.
