Abstract
In his classic textbook,The History of Biology, Erik Nordenskiöld suggested that there had existed, throughout the nineteenth century, not one but two distinct forms of plant geography. He designated one of these traditions of inquiry ‘floristic’ plant geography, tracing its origins back to the work of Carl Linnaeus on species and their distributions. The second form Nordenskiöld termed ‘morphological’, by which he meant that its practitioners concentrated upon the study of vegetation rather than flora. He located the origins of this tradition of inquiry within the botanical work of Alexander von Humboldt.
