Abstract
With the purpose of studying dry grassland plant groups in northwestern Algeria, we were led to sample and collect plant material. The identification and comparison with the current resources allowed us to add three taxa Echium modestum Ball, Plantago benisnassenii Romo, Peris & Stubing and Teucrium doumerguei Sennen to the Algerian flora. Two of these species, up to now endemic of Beni Snassen, eastern Morocco, are reported for the first time in the Traras Mountains. E. modestum is more widespread in Morocco than the other two. Their distributions, taxonomic and chorological statuses are discussed with an overview on the ecology of the localities where they were reported.
