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.
"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. Because of their great antiquity they have been described as living fossils and the coelacanths of the plant world." "Cycads were an important source of food for the dinosaurs and, despite their toxicity, they have been prepared for food and valued by many cultures. Today they may be regarded as relicts, still widely distributed but diminished in diversity and persisting only in small disjunct communities. 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 easy both to read and to understand. The book covers all 185 living species in their 11 genera. It has over 250 color photographs, many descriptive line drawings, identification keys, distribution maps, and 16 fine old color engravings previously hidden away in antique volumes. David records the prehistory and history of cycads and their economic importance. He provides detailed information on their cultivation, biology, and propagation. The book will appeal to gardeners, landscape architects, horticulturists, botanists, conservationists, and curious general readers alike."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

"This user's guide covers the highly threatened cycad family and how it is regulated by the Convention on International Trade in Endangered Species (CITES). The text is written for the non-expert and the guide explores the major groups of cycads in trade, their distribution, conservation status, use and levels of trade as well as the likelihood of illegal trade. Exemptions from CITES regulations are also outlined, together with suggestions to aid enforcement. The guide includes a fully illustrated PowerPoint training presentation and a checklist of cycad species, their distribution and synonymy."--P. [4] of cover.
Palm and cycad specialist David L. Jones updates the 1993 publication of this volume, adding 117 recognized taxa (for a total of 302 covered) and including numerous nomenclatural corrections. The first ten chapters address the history, conservation, structure, economic importance, biology, cultivati.
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.

This Special Issue on the Systematics and Phylogeny of Weevils presents 31 new research papers on one of the most diverse and successful groups of animals on Earth, the beetle superfamily Curculionoidea. It was in part inspired to commemorate the extraordinary life and scientific achievements of Guillermo (“Willy”) Kuschel (1918–2017), who shaped this field of science over the last century like no other weevil systematist. The papers in this memorial issue span weevil faunas from all over the globe, including South and Central America, Africa, Europe and the Near East, South-East Asia, New Guinea, Australia and New Zealand. They include major advances on the phylogeny and classification of the “broad-nosed” weevils (Entiminae), on the weevils associated with American cycads and on the unique extinct weevil fauna preserved in the 100-million-year-old Burmese amber, when weevils started to diversify alongside the oldest angiosperm plants. They comprise a tribute to Willy Kuschel, the proceedings of a weevil symposium held in his honor in 2016 in Orlando, Florida, 24 systematic studies (including seven phylogenetic analyses) and five other contributions on the diversity, biology, distribution, evolution and fossil history of weevils. In the papers collated in this volume, 30 new genera and 92 new species of weevils are described and a new family of extinct weevils is recognized.
