Daviesia


Daviesia, commonly known as Bitter-peas, is a large genus of flowering plants in the legume family. They are native to Australia, with a centre of diversity in Western Australia.
The genus is named in honour of Hugh Davies, a Welsh botanist. They have nitrogen-fixing bacteria contained in root nodules like other genera in their family.

Description

The leaves of Daviesia species are like phyllodes. They are usually hard, frequently prickly, frequently
circular in section, and sometimes reduced to scales. Some
species have cladodes, e.g., D. alata.
The roots of many Daviesia species have a mode of secondary thickening in which successive arch-like
cambia arise outside the roots of the previous season, creating rope-like structures
on the roots.
