More about Cycads

Cycad enthusiasts today are fortunate in having a wealth of excellent literature readily available. Two recently published books in particular stand out as essential reading:

  • Norstog, K.J. and Nichols, T.J. 1997. The Biology of the Cycads. Cornell University Press, Ithaca.

  • Jones, D.L. 1993. Cycads of the World. Reed, Chatswood.

    Earlier literature up to the mid-1980's has been comprehensively indexed and annotated by

  • Read, R.W. & Solt, M.L. 1986. Bibliography of the living cycads. annotated. Lyonia 2(4): 33-199.

    and there are also comprehensive although somewhat older publications and bibliographies dealing with economic and cultural significance of cycads

  • Thieret, J.W. 1958. Economic Botany of the cycads. Economic Botany 12: 3-41.

    and toxicology and the medical implications

  • Whiting, M.G. 1963. Toxicity of the cycads. Economic Botany 17: 271-302.
    All references cited The Cycad Pages are listed in the bibliography for those interested in more detailed reading on all aspects of cycads.

    The Net has also become a great source of information and news. Try:

  • Introduction to Cycads, University of California, Berkeley
  • The Gymnosperm Database by Christopher J. Earle
  • The Virtual Cycad Encyclopedia by Jody L. Haynes
  • Species descriptions at the Palm and Cycad Societies of Australia pages.
  • Cycads of Mexico (A WWW demo of the CD-ROM)

    Or just type "cycads" into your favourite net search engine.

    There are also great sites for cycad relatives and ecological associates. See the excellent Ginkgo biloba Pages by Cor Kwant.
