Volume 2 of the exhaustive, definitive. Every cactus in the world. Full botanical descriptions. Thorough statement of nomenclature, habitat, detailed finding keys. The one book needed by every cactus enthusiast. Total in set: over 1,275 illustrations.
This unique reference work presents the first comprehensive taxonomy of Coryphantha, with a complete key to the genus. It contains a new taxonomic classification of all 43 species and 11 subspecies, with morphological and ecological descriptions of these cacti, which grow in Mexico and the South of the USA. The work comes after many years of the authors commitment to cacti. During their ongoing work to map out the nomenclatural of this genus, the authors even discovered some new plants. More than 300 high-quality colour photos showing the various cacti and their habitats as well as distribution cards and illustrations explaining the morphological details complement the text. Written in an easy-to-follow style and with a chapter on cultivation conditions, the work will not only be an invaluable reference manual for taxonomists and horticulturalists but also for hobbyists and plant collectors.
Cactus plants have intrigued marking due to their great capacity to survive in harsh environments, their usefulness and, also their exotic beauty. In response to an increased demand for knowledge about these plants this book presents practical information on cultivation of cacti successfully. This work, richly illustrated with drawings and pictures, is a key tool for those who seek references on the cultivation and botany of Cactaceae, keeping in mind that publications on this subject are very rare
Although cacti such as the saguaro and organ pipe have come to define the Sonoran Desert for many people, they represent some 170 species of columnar cacti found in many parts of the Americas. These giant plants are so dominant in some ecosystems that many species of animals rely on them for food and shelter. They are pollinated by bats in central Mexico and Venezuela, by birds and bees in northern Mexico and Peru. This book summarizes our knowledge about the ecology, evolution, and conservation of columnar cacti and their vertebrate mutualists to show that the very survival of these cacti depends on animals who pollinate them and disperse their seeds. Contributors from the United States, Mexico, Venezuela, and Colombia explore aspects of geology and evolution that have forged this relationship, review findings in anatomy and physiology, and discuss recent research in population and community ecology as well as conservation issues. Ranging from the Sonoran Desert to the northern Andes, these studies reflect progress in understanding how abiotic and biotic factors interact to influence the evolution, distribution, and abundance of cacti and mutualists alike. In addition, this book examines the ways in which humans, through the process of domestication, have modified these plants for economic benefit. The contributors also review phylogenetic relationships between cacti and nectar-feeding bats in an effort to understand how bat-plant interactions have influenced the evolution of diversity and ecological specialization of both. Because of the number of migratory pollinators feeding on columnar cacti, the authors make conservation recommendations aimed at preserving fully functional ecosystems in arid portions of the New World tropics and subtropics. Columnar Cacti and Their Mutualists provided a benchmark for both conservation efforts and future research.
