Temperate biogeography and an intemperate botanist

This paper is a reply to Heads (1985). In his attack on my previous publications (Humphries, 1981a, b) Michael Heads deliberately tries not to enter in the spirit of enquiry. So obsessed is he with the idea that everything written by Léon Croizat is of cardinal importance for biogeography that almost anything else with a different point of view is considered unscholarly. Although some of his comments on my paper are valuable, particularly those of a technical nature, his desire to take views out of context frequently gives rise to misunderstandings.
