Its first contact with European explorers was in 1699, when the English buccaneer William Dampier collected it on his second sea voyage along the Western Australian coast.
In 1999 is was proposed to reclassify the pea into a new genus (Willdampia - in William Dampier's honour), but this was not accepted.
Also known as the Sturt Pea, it flowers in late winter and early spring - especially after good autumn rain.
Sturt's Desert Pea can be found in the broad band of arid country that stretches from western New South Wales across South Australia to the west coast of Western Australia around Port Hedland. It also includes the south-western parts of Queensland and the Northern Territory.
The sage coloured leaves are about 15mm long.
All of the photos were taken near Broken Hill in New South Wales.
