Notes on xenophytes detected in Catalonia, Spain

Abstract

NotES oN xENoPhYtES dEtEctEd iN cataloNia, SPaiN.— These notes include six species, among them three grasses: Axonopus compressus, Dactyloctenium aegyptium and Megathyrsus maximus, the crucifer Lepidium densiflorum, a dwarf annual composite Soliva sessilis, and the climbing Aristolochia sempervirens (Aristolochiaceae), all present in or around Barcelona, Catalonia (northeastern Spain). All are recent additions to the increasing alien flora of the region. Some have been recorded previously from the Iberian Peninsula but are new to Catalonia; others appear to be new records for the peninsula.
