As currently circumscribed, Boronia (Rutaceae) is a large Australian genus of 148 species distributed in all states and mainland territories, and Boronella is confined to New Caledonia and contains ~four species. We present molecular phylogenetic analyses of these genera, based on chloroplast (trnL–trnF) and nuclear (ITS, ETS) DNA sequences, to assess their relationships and infrageneric classification. Analyses strongly support the monophyly of a Boronia+Boronella clade and that Boronella is nested within Boronia. They also support the monophyly of Boronella and Boronia sections Algidae, Valvatae and Cyanothamnus, and ser. Pedunculatae (sect. Boronia), but resolve sect. Boronia and ser. Bor..
