Aportaciones a la Flora de Galicia. XIII

New collection campaigns as well as the examination of previously collected herbarium material have allowed to obtain interesting findings, beyond, even, the Galician sphere. A new combination is proposed, \textit{Ceratocapnos picta} (Samp.) Silva-Pando \& J. Bal. comb. nov. for which a lectotype is designated, and the name \textit{Atriplex nivea} Merino is lectotyped and designated epitype. Two new species are registered for Europe (\textit{Robinia viscosa} Vent. and \textit{Setaria sulcata} Raddi); two taxa for the Iberian Peninsula (\textit{Lunaria annua} subsp. \textit{pachyrrhyza} (Borbás) Maire \& Petitm. and \textit{Cenchrus $\times$ cupreus} (Thorpe) Govaerts); another three for Spain (\textit{Ceratocapnos picta} (Samp.) Silva-Pando \& J. Bal., \textit{Fuchsia magellanica} Lam. y \textit{Ipomoea coccinea} L.); one for Portugal (\textit{Bacharis halimifolia} L.); 14 news for Galicia; six novelties for A Coruña, four for Lugo; three for Ourense and three for Pontevedra. Some comments on four species are also added. The results show that it is necessary to continue with the field work and review of materials to achieve a greater degree of knowledge of the Galician flora.
