In the Oued Drin there were 16 species belonging to 12 botanical families. The botanical family the best represented is that of Brassicaceae (3 species). Amongthe 1 6 species sampled 4 plants are 12 of the perennial and ephemeral. The largest total wealth is noticeable in the middle station 01 oued representing 6 species, then station 2 Oued with 9 species, then station 3 in oued with 9 species. The relative frequency is varied between 5.5% to 83%, of which the most important is Pergularia tomentosa. The density of the flora is very different depending on the species, between the same species and the stations of studies. The recovery depends of abundance dominance and the individuals flowering stage.
