Based on the digitized herbarium records housed at the National Herbarium of the Netherlands I developed high spatial resolution patterns of Borneo's botanical richness, endemicity, and the floristic regions. The patterns are derived from species distribution models which predict a species occurrence based on the identified relationships between species recorded presences and the ecological circumstances at those localities. A new statistical method was developed to test the species distribution models. Several areas of high richness and endemicity were added to the list of previous known ones. Furthermore, the lowland rain forest of Borneo, previously recognized as one floristic region, in fact harbours at least four (and possibly six) different floristic regions.UBL - phd migration 201
