Written by retired nurseryman, seedsman and horticultural writer T1000 Decorative Plants, 1983' this book attempts to provide a comprehensive guide to the palms and cycads of the world. Contains information on origins, habitat, propagation and care of both species. Includes colour photographs and descriptions of all known varieties and a detailed index. Profusely illustrated.
Cycads superficially resemble palms and are often misidentified as such. However, cycads are actually a unique assemblage of primitive plants that have been around for at least 250 million years. They have become highly sought after for gardens, both private and public, and their present status as endangered plants has engendered an upsurge of interest in their conservation. With Cycads of the World, David Jones has achieved that difficult task of writing a scientifically accurate text, which is both easy to read and to understand. For this second edition David Jones has added information covering over 100 new species and subspecies of cycads, and updated his material on the 200 species from the first edition. Each entry includes a full description, distribution and habitat information, and a detailed cultivation and propagation guide. Over 360 color photographs plus many other illustrations and maps facilitate easy identification for all living species. This second edition of Cycads of the World makes a fine addition to the library of anyone interested in exotic plants, including gardeners, landscape architects, horticulturalists, botanists, and the curious reader alike.
This volume presents the current state of our knowledge of the classification of the approximately 300 species of cycads. It includes contributions from leading researchers from Australia, China, Italy, Mexico, South Africa, Thailand and the USA. It has been developed from papers presented at a workshop held in 2002 at the Montgomery Botanical Center. The book provides guidelines for the designation of species, species boundaries and species groupings, thus clarifying what has been a confused area of research.
Thoroughly referenced and generously illustrated, this book discusses all aspects of cycadology. A small group of ancient palmlike seed plants noted for their beautiful foliage and often brightly colored cones and seeds, cycads are believed to have been among the first seed-bearing plants. Seed bearing was the basis for their worldwide dominance from about 300 million years ago to about 70 million years ago, when today's familiar flowering plants gained ascendancy. In recent years, interest in cycads has increased, partly as a result of the need for a more complete identification of the range of toxic and carcinogenic substances these plants produce and partly because of the recognition that some compounds from cycads may prove valuable in biomedical research. Many cycads have recently been identified as endangered species, including some that seem to have survived virtually unchanged since the Mesozoic era. Cycads have a specific importance, now at risk of being lost forever, for the information they offer on the origins and evolution of seed plants. Knut J. Norstog and Trevor J. Nicholls discuss cycad anatomy, reproduction, physiology, and growth. They also focus on population biology and the fossil cycadophytes, as well as genera and species from both the Old World and the New World. The Biology of the Cycads is illustrated with numerous maps, diagrams, and drawings, as well as more than 350 photographs, in black and white and in color.
You will find inside profiles of 184 palm and 35 cycad species, as well as expert advice on selecting, planting, and propogating this book has step-by-step instructions and guide to matching palm species to indoor and outdoor settings.
Only a bunch of heavily armed gardeners can save the world's most valuable plant. A priceless plant, a rare African cycad thought to be extinct and prized by collectors, has been discovered, then stolen. Joanne Flack, widowed and broke, is the prime suspect for the crime. While supposedly hiding out in London she single-handedly foils a terrorist plot, killing a lone-wolf gunman. Former mercenary turned CIA contractor, Sonja Kurtz, uncovers a link between the missing plant and the terrorist who tried to kill Joanne. The US Government thinks that if it can find the missing cycad it can foil an attack to rival 9-11. Hot on Joanne’s trail is retired US Fisheries and Wildlife Department special agent Rod Cavanagh who knows his plants and knows his target – he’s her former lover. Joanne is a member of the Pretoria Cycad and Firearms Appreciation Society. She, Sonja and Rod enlist the help of this group of ageing gardeners and gun nuts to find a plant worth a fortune and the traitor in their midst who is willing to kill for it.
