Sažetak

Ninety eight species of angiosperms belonging to 34 families were identified in the Wadi Allaqi Biosphere Reserve (S. E. Egypt): 33.7%annuals and 66.3%perennials. The members of Leguminosae contributed 19.4% of the total flora, considering the most dominant family inWadi Allaqi. Three herbaceous species were recorded for the first time in this region: Iphiona scabra, Chenopodium album and Lotus deserti. Eight vegetation clusters were obtained and categorized into 4 distinct groups according to soil composition and chemical characteristics (concentration of bicarbonates, calcium, magnesium and chlorides), and intensity of inundation by the water of Lake Nasser.
