Abstract: At planetary as well as local scale, the relief forms induce spatial modifications of the structure of the main bioclimatic factors such as temperature, rainfall, humidity, insolation, evaporation and nebulosity. Depending on the area under consideration, these changes result in more or less strong floristic gradients. We wanted to study this phenomenon in the Lesser Antilles (island microsystems). We carried out floristic surveys in circa twenty stations within the vegetation cover of a hill in the south of Martinique influenced by the dry bioclimate (summit at 200 meters altitude).............
