Abstract

This work provides data on very rare alien plants in Catalonia and also new locations of geographical interest about not so rare species. 8 taxa (Aloiampelos striatula, Aurinia saxatilis, Cotoneaster ×suecicus, Dianthus plumarius, Forsythia viridissima, Oenothera villosa subsp. villosa, Phyllostachys sulphurea and Rosa banksiae) are new to the Iberian flora and 3 to the Catalan flora Argyranthemum frutescens, Leucanthemum ×superbum, Opuntia bonaerensis). The naturalization in the territory of Cotoneaster perpusillus is also confirmed. Additionally, we confirm that Erigeron karvinskianus is becoming in recent years a conflicting invasive plant on the Montserrat mountain , where it competes with the native flora of the cliffs.
