Narcissus ×perezlarae Font Quer is a natural hybrid between N. cavanillesii A. Barra & G. López and N. serotinus L, two autumnal flowering geophytes. Although scarce populations had been found in Spain since 1882, in the areas where the distribution of the two parental species overlaps, this is the first report of this taxon in Portugal. N. ×perezlarae was found in the context of conservation projects regarding the effects of the Alqueva dam in vascular plants, especially on N. cavanillesii, a species considered as Critically Endangered (CR) in Portugal. Its history, morphology, ecology and distribution is here illustrated as well as a brief discussion concerning the evolutionary implications of the presence of N. ×perezlarae in Portugal.
