1 The dispersal mode adopted by a plant species is frequently associated with other attributes of the and its habitat. In this paper we review these associations present set hypotheses which, when considered together, make probabilistic prediction species. When applied to list, can be used generate spectrum, i.e. percentages different modes that have been adopted. 2 formulation such has several purposes: (i) summarize existing knowledge about adaptations their interrelations plants habitats; (ii) couch in way falsifiable predictions made; (iii) arrive at provisional conclusions which factors are most important shaping evolution or environments. 3 relationships between habitats lead following conclusions; seeds larger than 100 mg tend adapted for vertebrates while those smaller 0.1 unassisted; seeds, however, mg, range all feasible; growth form stature (sometimes relation canopy height vegetation) seem exclude certain modes; availability specific vectors seems rarely an determinant mode; (iv) physical environment also important, except indirectly through influence on seed size.
