Abstract
Gaudinia maroccana is considered a Moroccan endemism. After a qualitative and quantitative study of 13 morphological characters of Gaudinia based upon 43 specimens from western Iberian Peninsula, northwestern Morocco and Azores Islands, with statistical analyses (correspondence analysis, box-plots and cluster), we can conclude that this species also occurs on the coast of Portugal. Some taxonomic remarks on G. fragilis, G. coarctata, G. hispanica and G. valdesii and a key for determination are presented.
