Abstract

We provide new records of 17 exotic plants in the Baix Llobregat region observed between the years 2011 and 2014. Two species are the first records for Europe: Acacia rostellifera Benth. and Trichloris crinita (Lag.) Parodi; two are new plants for the Iberian Peninsula: Bouteloua dactyloides (Nutt.) Columbus and Nassella tenuissima (Trin.) Barkworth; three are recorded by their first time in Catalonia: Atriplex semibaccata R. Br., Oenothera speciosa Nutt. and Verbena incompta P. W. Michael; five correspond to first records in Baix Llobregat: Parkinsonia aculeata L., Phacelia tanacetifolia Benth., Physalis peruviana L., Salpichroa origanifolia (Lam.) Baill. and Verbena brasiliensis Vell. The remaining species are very rare in the studied area: Abutilon grandifolium (Willd.) Sweet, Asperugo procumbens L., Eclipta prostrata (L.) L. and Oenothera indecora Cambess.
