Aeonium haworthii Webb & Berthel. and Crassula ovata (Mill.) Druce (Crassulaceae): New records for the Algerian alien flora

Article scientifique 2023 Anglais

Résumé

This paper expands the list of alien species of Crassulaceae that escaped from cultivation in Algeria and mainland North Africa, as a result of the discovery of two new alien species in the Skikda region (northeastern Algeria) in 2021 and 2023.Aeonium haworthii was recorded in a semi-natural habitat, the maritime cliff of the Stora region, and seems completely naturalized in this locality.Crassula ovata was recorded in an urban environment, where it colonizes balconies and roofs; at present, this species is considered to be a casual.These results are supported by field photos of both species, a distribution map and an updated list of alien Crassulaceae species reported so far from mainland North Africa (Algeria, Morocco and Tunisia).
