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.
