Four new combinations are proposed in order to have these names available for the treatment of Pseudognaphalium in Chile and for the Flora of Argentina: Pseudognaphalium aldunateoides (J. Rémy) C. Monti, N. Bayón & S.E. Freire, Pseudognaphalium andicola (Phil.) C. Monti, N. Bayón & S.E. Freire, both from Argentina and Chile, Pseudognaphalium glanduliferum (Griseb.) C. Monti, N. Bayón & S.E. Freire, from Argentina, and Pseudognaphalium perpusillum (Phil.) C. Monti,N. Bayón & S.E. Freire, from Chile. Two taxa are newly synonymized: G. phaeolepis Phil. with G. aldunateoides J. Rémy, and G. diminutivum Phil. with G. perpusillum Phil. Lectotypes are here proposed for: Gnaphalium andicola, G. diminutivum and G. phaeolepis. Additionally, a table featuring diagnostic characters to distinguish between Gnaphalium and Pseudognaphalium is provided as well as illustrations of phyllaries, achenes, and pappus bristles for each species.
