The Biology of The Cycads represents a compendium of data on all aspects of cycad biology, summarising very concisely a vast repertoire of widely scattered and very diverse research information. Despite this extensive coverage, the book is clearly written and well organised into readily digestible sections. Topics covered include morphology, anatomy, reproductive processes (especially pollination and insect associations - a special interest of Norstog's), population dynamics, toxicity, cytology, cytogenetics, cycad fossils and species descriptions of cycads grouped into Old World and New World taxa.
As a novice in the field of cycad colelction/conservation, I found the book very handy and usefull. Some of the content may be a little to scientific for the general person out there, but otherwise this is an excellent book.
