ResumoALMEIDA, J.D. & FREITAS, H. 2001. The exotic and invasive flora of Portugal. Bot. Complutensis 25: 317-327. The presence of exotic plants in Portugal has increased during the last two centuries. Aliens represent today more than 15 % of the Portuguese flora. We present a report of the exotic flora of Portugal, based on available bibliography, herbarium specimens and field surveys. We have used the Country’s traditional division in eleven provinces, and the species geographical distribution is given accordingly, since this is the usual taxonomical methodology. The progression of alien plants by families along time and some ecological characteristics are also discussed.
