The volume is aimed at students of botany and geology and is richly illustrated. The opening of the volume sets its scope in a preface that explains the emphasis on gymnosperms and postpones a global survey of past floras, then launches into a detailed primer on living Cycadales to prepare readers for fossil comparisons.
