Originally published in 1981 Historical Plant Geography is an introductory treatment of historical plant geography and stresses the basic theoretical frame of the subject. The book is about neither the study of vegetation nor the concept of the ecosystem, instead focusing on the much older tradition concerned with analysing the geographical distribution of individual species and natural plant groups. Important areas are discussed, such as global plate tectonics and sea-floor spreading, plant maps are introduced and there is a basic treatment of recent advances in plant taxonomy. The book will appeal to students and academics of geography, botany, ecology and environmental sciences.

Historical Geography of Crop Plants is devoted to a variety of staple and food crops, as well as fodder, fiber, timber, rubber, and other crops. The origins and histories of many of these crops have been clarified only recently by new research. The book has been arranged alphabetically by family and higher taxa for easy reference. Within families, species and cultivars are listed chronologically and geographically. The taxonomy and geography of probable wild progenitors have been outlined, and archeological evidence (when available) and historical evidence on region and domestication are traced. The subsequent evolution and spread of many domesticated species are examined, and the reasons behind the diversity in crop histories are explored. Historical Geography of Crop Plants will be a useful reference for botanists, economic botanists, ethnobiologists, agronomists, geographers, and others interested in the subject.
