  Presentem cites de 34 plantes aŀlòctones trobades a Catalunya i al País Valencià fruit principalment del treball de camp dut a terme en aquests territoris. Com a novetats, en citem dues per a Europa –Agave albomarginata i Euryops chrysanthemoides × E. pectinatus–, cinc per a la península Ibèrica –Opuntia chlorotica, Ptelea trifoliata, Rosa multiflora, Siphonostylis unguicularis i Solandra maxima–, vuit per a Catalunya –Aspidistra elatior, Echinopsis oxygona, Mammillaria elongata, Morus kagayamae, Paraserianthes lophantha, Proboscidea louisianica, Tara spinosa i Vachellia caven–, i vuit per a les diferents províncies catalanes: per a Barcelona, Malephora purpureocrocea, Oenothera lindheimeri, Solanum pseudocapsicum, Tecomaria capensis i Tipuana tipu; per a Girona, Bouteloua dactyloides; per a Lleida, Erythrostemon gilliesii; i, per a Tarragona, Agave lophantha. Tot i no ésser novetats, també aportem noves observacions de plantes poc citades. La majoria de les espècies són presents al territori de forma ocasional (tot i que en alguns casos estan plenament naturalitzades), i en general hi són com a conseqüència d’activitats principalment de jardineria.
