First record of Ficus microcarpa L. f. (Moraceae) in Algeria

The escape from cultivation of Ficus microcarpa (Moraceae, Magnoliopsida) in Algeria is here reported. Several localities where the species reproduces from seeds have been discovered recently in northeastern Algeria. A map of its current distribution in the study area is provided. The species colonizes mainly urban habitats (walls, balconies and sidewalks) but its propagation in the natural environment is being facilitated by birds that disseminate the seeds over long distances. Ficus microcarpa can be considered as in the process of naturalization in Algeria. An updated key to species of the genus Ficus in Algeria is provided.
