About the Book
Cycads resemble palms but are taxonomically quite different. They are significant as ornamental plants but, as an important evolutionary link in the plant kingdom and as an internationally endangered tropical plant group, cycads have also become the focus of evolutionary and conservation studies. This volume presents the classification of 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 Centre in Florida, USA. The book provides guidelines for the designation of species, species boundaries and species groupings.
