Sobre la presencia de cactáceas naturalizadas en la costa meridional de Cataluña

Abstract

The authors report on the finding of eight new alien cacti naturalised in the Baix Camp (Tarragona). Three of these are new records for Europe, two are new records for Spain and one is a first record for Tarragona province. Two further species are not new floristic records however some revision of their status in Catalonia is required. Discussed is the extensive use of alien plant species in garden design in the area and the mildness of the local climatic conditions which has resulted in the greatest accumulation of naturalised cacti in Europe.
