New additions to the exotic vascular flora of continental Portugal

Abstract

In this paper, based on mainly recent bibliography and some own field observations, 105 more taxa (neophytes) are added to the catalogue of the exotic (or xenophytic) naturalized or subspontaneous vascular flora of continental Portugal, which includes now 772 taxa (species, subspecies, varieties and hybrids), a growth corresponding to more than 15 % of the previous total number of 667 taxa, since our last reassessment, published in 2012 (Almeida & Freitas 2012), and our earlier surveys (Almeida & Freitas 2006; Almeida 1999).
