                         vegetation in the Amazonian lowlands is still unclear. This 
                         research integrated the geological history and plant inventories 
                         of a white sand vegetation patch confined to one large fan-shaped 
                         sandy substrate of northern Amazonia, which is related to a 
                         megafan environment. We examined floristic patterns to determine 
                         whether abundant species are more often generalists than the rarer 
                         one, by comparing the megafan environments and older basement 
                         rocks. We also investigated the pattern of species accumulation as 
                         a function of increasing sampling effort. All plant groups 
                         recorded a high proportion of generalist species on the megafan 
                         sediments compared to older basement rocks. The vegetation 
                         structure is controlled by topographic gradients resulting from 
                         the smooth slope of the megafan morphology and microreliefs 
                         imposed by various megafan subenvironments. Late 
                         Pleistocene-Holocene environmental disturbances caused by megafan 
                         sedimentary processes controlled the distribution of white sand 
                         vegetation over a large area of the Amazonian lowlands, and may 
                         have also been an important factor in species diversification 
                         during this period. The integration of geological and biological 
                         data may shed new light on the existence of many patches of white 
                         sand vegetation from the plains of northern Amazonia.",
