SOME CAMEROON EXAMPLES OF A POSSIBLE CONNECTION BETWEEN GEOLOGICALPHENOMENA AND VEGETATION
The paper includes the following: a morphological, ecological and geographical description of the monophytic populations (unique in humid African forests) of Gilbertiodendron dewevrei (Caesalpiniaceae) in south-east Cameroon; probable relic character of these populations; comparison with other gregarious species in the Caesalpiniaceae and Sapotaceae; hypothesis of the reduction of hydrostatic levels; — the same hypothesis related to the deep forested valleys of the Sudano-Zambezi plateau of Adamaoua in the centre of Cameroon and — a study of a sandstone ‘inselberg,’ overhanging the dense humid evergreen forest of south-west Cameroon, with compound vegetation (a type of ‘miombo’ but including maritime littoral plants as well as endemic elements); hypothesis of recent epirogenic movements, of tectonic movements, of volcanic effects (Mont Cameroun).
