Abstract

The distribution, ecology, probable modes of dispersal and taxonomic relationships of five species of Chrysobalanaceae and one of Meliaceae and Hernandiaceae are summarized. Most of these show trans-oceanic disjunctions and, in Africa, behave as ecological and chorological transgressors; morphologically they are variable. The potential importance of transgressors in the origin of new species and of evolutionary innovations, and in the interpretation of disjunctions is discussed.
