Loasoideae is investigated with sequences of the chloroplast trnL(UAA) intron, all genera and infrageneric entities are included in the analysis. Loasaceae subfam. Loasoideae is monophyletic, and the two most speciose, andmonophyletic, clades(which account for approximately 90% of the species total) are Nasa andthe so-calledSouthern AndeanLoasas ( Blumenbachia, Caiophora, Loasa s.str., Scyphanthus), but the phylogeny of the remainder is not completely resolved. The data underscore a basal position for Chichicaste, Huidobria, Kissenia, andKlaprothieae ( Xylopodia, Klaprothia, Plakothira). High bootstrap support values confirm the monophyly both of Klaprothieae and Presliophytum (when expanded to include Loasa ser. Malesherbioideae). Aosa and Blumenbachia are not resolvedas monophyletic, but have clear morphological apomorphies. Within Nasa,‘‘N. ser. Saccatae’’ is paraphyletic, and‘‘ N. ser. Carunculatae’’ is polyphyletic. However, the N. triphylla group in ‘‘N. ser. Saccatae’’ is a well-supportedmonophyletic group, as is N.
