Abstract

Phylogenetic hypotheses are presented for Pultenaea based on cpDNA (trnL–F and ndhF) and nrDNA (ITS) sequence data. Pultenaea, as it is currently circumscribed, comprises six strongly supported lineages whose relationships with each other and 18 closely related genera are weak or conflicting among datasets. The lack of resolution among the six Pultenaea clades and their relatives appears to be the result of a rapid radiation, which is evident in molecular data from both the chloroplast and nuclear genomes. The molecular data provide no support for the monophyly of Pultenaea as it currently stands. Given these results, Pultenaea could split into many smaller genera. We prefer the taxonomically stable alternative of subsuming all 19 genera currently recognised in Pultenaea sensu lato (= the Mirbelia group) into an expanded concept of Pultenaea that would comprise ~470 species.
