New alien plants in Baix Empordà (Catalonia, Spain).
We present new localities of some exotic plants that generally have increased their distribution area as a result of human activities. One was unknown in the Iberian Peninsula, Solamum torvum Swartz, some were unknown in Catalonia, Kalanchoe daigremontiana R. Hamet & H. Perrier, Podranea ricasoliana Sprague, Tecomaria capensis (Thunb.) Spach, and others are new for the region of Girona or have increased their distribution area considerably. We give information about the habitat where these species grow, degree of naturalisation, places where other botanists found them, evaluation of occupied area, and flowering time.
