This volume comprises updated nomenclature, distribution, and habitat data for the species in the area covered in the four parts of Flora Palaestina. The distribution data are presented here in individual maps for each of the species recorded in the study area (defined as lying west of 36°E).

Four main phytogeographical regions – the Mediterranean, Irano-Turanian, Saharo-Arabian, and Sudanian – meet in Israel. The area's broad climatic and edaphic diversity is largely responsible for its botanical wealth – some 9.06 species per 100 sq. km. Of the 2,750 species listed herein, 276 were not previously recorded in Flora Palaestina. The 18,000 species-per-district records that form the basis of Flora Palaestina have been expanded to some 28,400, based largely on the author's investigations over the course of some forty years.
