A molecular phylogeny of Boronia (Rutaceae): placement of enigmatic taxa and a revised infrageneric classification

A phylogeny of Boronia (Rutaceae) is presented on the basis maximum parsimony and Bayesian analyses plastid (psbA–trnH, trnL–trnF, rbcL) nuclear (ITS, ETS) markers. Analyses either or sequences recovered same major clades, although with conflicts in resolution among them. The existing classification largely confirmed; sections Boronella, Pedunculatae Valvatae are supported, monotypic Alatae Imbricatae isolated. corynophylla Paul G.Wilson removed from section Algidae to new Corynophyllae. coriacea placed, B. inornata Turcz., Inornatae. humifusa G.Wilson, ovata Lindl. scabra placed Ovatae. koniambiensis retained Boronella but a series. Section resolves into two clades that confined south-eastern south-western Australia, latter containing three strongly robustly supported subclades. An identified problem within lack morphological apomorphies assist formal classification. Despite this, four series, justified results molecular analysis, proposed. Relationships 10 remain poorly resolved apart sister relationships Pedunculatae, and,
