Six new taxa of the Poaceae family are added to the non-native flora of Tunisia: Cenchrus longisetus M. C. Johnst., Digitaria ciliaris (Retz.) Koeler, Eleusine indica (L.) Gaertn., Eragrostis cilianensis subsp. thyrsiflora (Willk.) H. Scholz & Valdés, Eragrostis pilosa (L.) P. Beauv. and Paspalum dilatatum Poir. Five of them are considered naturalized and horticultural trade is considered the most likely pathway for their introduction, whereas Eragrostis pilosa (L.) P. Beauv., might have been introduced as impurity in cereals for field crops. Populations of Tunisian E. pilosa are characteristic in possessing glandular pits, especially on inflorescence branches, a character not observed in E. pilosa s. str. in Europe and the Mediterranean area. Actual distribution and taxonomic notes are also given for all newly reported reported taxa.
