The Cycads" by Loran M. Whitelock
This reference provides an up-to-date treatment of cycads, which are the most primitive surviving gymnosperms. Whitelock (owner of a cycad nursery) describes all of the known cycad species throughout the world and gives practical advice on cultivation and propagation. In addition, he discusses the historical human use of cycads, distribution past and present, classification, morphology and reproduction, conservation and protection, and other topics. The book also contains lists of cycads grouped by characteristics from leaf color to cold tolerance, and 500-plus color photographs and b&w illustrations of the 11 genera and nearly 300 species.

"Cycads of The World" by David L. Jones
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, cultivation, diseases, propagation, and garden uses of cycads; the remainder is devoted to an encyclopedic listing arranged alphabetically by genus. Botanical keys have been deleted, as the genera are too large and complex; new photographs have been added; and appendices include a list of authors associated with the naming of cycads and a comprehensive list of synonyms.
