Medjahdi, B., Letreuch-Belarouci, A., Maazouz, S. & Taïbi, K.: Diversité floristique des sub- éraies des monts de Tlemcen (Nord Ouest Algérien). — Fl. Medit. 28: 67-77. 2018. — ISSN: 1120-4052 printed, 2240-4538 online. The floral diversity’s analysis of cork oak forests in Tlemcen mounts has revealed the existence of 429 taxa belonging to 65 families and 265 genera. The comparaison of the flora in three cork oak forests allowed us to highlight the occurrence of an important original flora, where 85 taxa are present only in the forest of Hafir-Zarrifette, 87 in the forest of Sidi Hamza-Ain SoukZerdeb and 65 belong to for the forest of Ifry, 84 taxa are common to all the three forests. The number of endemic and/or rarely inventoried taxa contains 14 endemic algero-moroccan and 17 ibero-algero-moroccan ; 9 are endemic to North Africa (Algeria, Morocco, Tunisia) ; and 11 are endemic to the Iberian peninsula and North Africa. So, despite the degradation of the endemic and rare flora, what remains, is often accompanied by stable species in all the three forests. These species can be used for the reconstruction of cork oak forests in the Tlemcen mounts.
