The bush-pea genus (Pultenaea) is one of the larger legume genera in Australia but has been difficult to define. We present a new classification of the group, recognising five genera instead of one using a large DNA based analysis of relationships. Three genera are newly described and one genus is reinstated, and these are almost entirely restricted to south-west Western Australia, with true Pultenaea being mostly restricted to eastern Australia.

SB23032Species delimitations in the Campomanesia xanthocarpa group (Myrtaceae): insights from molecular markers and taxonomy

Inclusive schematic representation of species delimitations in the genus Campomanesia Ruiz & Pavón.

Species of Campomanesia are economically important, being used for food and in forestry. Some of these are morphologically similar, raising doubts regarding identification. Seeking to solve this, we performed population genetic analyses with a complex of species: Campomanesia adamantium, C. costata, C. littoralis and C. xanthocarpa. Results indicated the re-establishment of Campomanesia rhombea and complexity of C. adamantium that should be explored based on additional tools. This study improves our understanding of the taxonomy of the genus. (Image credit: M. Ibrahim Uehbe de Oliveira.)
