Abstract
Recent botanical surveys undertaken in central and northern Tunisia (North Africa) since 2014, mainly within coastal regions, yielded new records for non-native succulents (casual or naturalising aliens) of vascular plant species belonging to Asparagaceae sensu lato (Dracaena draco (L.) L. subsp. draco, Sansevieria hyacinthoides (L.) Druce, S. trifasciata Prain, Yucca aloifolia L. and Y. gloriosa L.). The reported taxa belong to three genera that represent first records for the vascular flora of Tunisia. Among these new taxa, Sansevieria hyacinthoides is first reported for North Africa and the Mediterranean area whereas Yucca aloifolia is here reported for the first time for North Africa. Distributions and morphological descriptions, as well as phenology and habitat, are given for each of these new records. Notes on their actual status and field photographs are provided.
