Abstract
Roadside vegetation was studied on field paths and along road verges outside settlements on both sides of the Straits of Gibraltar. 180 phytosociological relevés have been sampled in different ecoregions of the Gaditanean and Tingitanean Peninsulas. CA and DCA were performed to evaluate the phytosociological classification. Stands at road verges are often dominated by species resilient to frequent disturbance. Such stands, poor in diagnostic species, are classified and named according to the deductive approach of KOPECK´Y & HEJN´Y. The lack of stenoic taxa is underlined by correspondence analyses. Due to the great variability of the physical environment and of human impact, roadside vegetation is floristically much differentiated and can be classified into 12 associations, 10 subassociations and some rank-less vegetation units. They belong to the classes Polygono-Poetea, Stellarietea, Artemisietea and Molinio-Arrhenateretea
