Aristolochia gigantea (Aristolochiaceae), Distimake dissectus, Ipomoea batatas (Convolvulaceae), and Passiflora caerulea (Passifloraceae) are newly reported from Tunisia and the distribution range of Anredera cordifolia (Basellaceae), Ipomoea indica and I. purpurea (Convolvulaceae) is extended as a result of botanical surveys during the last two decades. All the species are considered casual to naturalizing aliens and the horticultural trade is the most likely pathway for their introduction. General macromorphological characteristics together with original photographs are provided. Actual distribution, ecological notes (habitat, phenology) as well as the degree of naturalization are reported.
