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.
