Ever since Sernander (1927), the plant part to be spread has been indicated, independently of its morphological value, as “diaspore” (from diaspeiro = I broadcast). Sometimes we find the terms “propagule”, “germule”, “migrule”, “chore” or “disseminule”. Sernander also gave a simple system, repeated here with some modifications. Its inadequacies will appear in the chapter on evolution. The system does not, of course, depend on function and agents, and is thus of little importance to us here.
