The floras of the Guineo-Congolian and Zambezian Regions,* except for a few cosmopolites, pluri-regional linking species and chorological and ecological transgressors, are almost mutually exclusive so far as the greater part of their areas is concerned. There is, however, a transition zone between them (White 1976a, in press, A) up to 500 km wide, where an impoverished Guineo-Congolian flora and an even more impoverished Zambezian flora interdigate or occur in mosaic, and, locally, intermingle. The precise distribution of végétation dominated by these floras is determined by local edaphic and climatic factors. Most of the Zaire part of this Congo-Zambezia transition zone is included in the Guineo-Congolian Region by Duvigneaud (1952), who, nevertheless, admits its transitional nature. Certain authors, e.g. Devred (1957) and Liben (1958), attempt to define a precise boundary between the Guineo-Congolian and Zambezian Regions. The general needs of biogeography, however, are equally well served if transitional zones are clearly recognized as such.
