Pultenaea
Pultenaea is a genus of flowering plants in the family Fabaceae- Faboideae that are native to Australia. They are known commonly as bush peas.
The genus is found in south west Western Australia and the eastern states. It is not considered to be monophyletic with suggestions of splitting it into six separate subgenera, under a larger genus of Pultenaea sensu lato, essentially the Mirbeliea group. The genus underwent explosive starburst radiation, with biogeographical divisions due to the Nullarbor Plain and the Winter/Summer rainfall boundary. Some species rely on fire regimes for germination, and are an understorey dominant and nitrogen fixer.
