Some contributions to the wall flora of the French coastland between Antibes and Menton (Côte d’Azur)

86 vascular plant species are observed on walls between Antibes and Menton. Most records are made on retaining walls and historical fortifications. 60,5 % of the plants are indigenous, 7,0 % are archaeophytes, 32,6 % are neophytes. Wooded species, at least 20 (23,3 %) play a more important role compared to Central Europe due to the climatically preferred area in the western Mediterranean. Some further species which may grow spontaneously in joints are pointed out, however clear evidence could not be found.
