The Biology Of The Cycads by Knut J. Norstog & Trevor J. Nicholls
“The authors have done a superb job of synthesizing information from scattered sources. A significant contribution to the field, their book is readily comprehensible and will appeal to a wide audience.” —Robert Ornduff, University of California, Berkeley
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 seedbearing 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, because of the information they offer on the origins and evolution of seed plants.
