A total of 195 species were recorded in the different sectors of Wadi Hashem cut-in the limestone plateau west of Mersa Matruh (Egypt). The distribution of these species in the different sectors of the Wadi as well as the phytochoria for the recorded species is provided. The highest number of species (157) was recorded in the stream part of the Wadi bed while the lowest number (34) was recorded in the three cliffs of the Wadi. Sixty seven species forming 34.36% of the total are typical Mediterranean (monoregional) taxa. About 93 species (47.69%) are bi- or pluriregional taxa with apparent Mediterranean affinities.
