What is the name of the flower in the picture?

'Crotalaria cunninghamii', also known as green birdflower, birdflower ratulpo, or regal birdflower, is a plant of the legume family Fabaceae, named Crotalaria after the Greek word for rattle, because their seeds rattle, and cunninghamii after early 19th century botanist Allan Cunningham. 'Crotalaria cunninghamii' is a short-lived perennial plant native to Australia and its habitat is the deserts, coastlands, drainage lines and sand dunes of the northern half of Western Australia and the Northern Territory.

This habitat is semi-arid to temperate regions in well drained soils. Green birdflower blooms from January to April. It is known as the Mangarr plant to the Nyangumarta Warrarn indigenous group. The green birdflower is a perennial shrub that grows to about 1–3 m (3 to 9 ft.) in height. It has hairy or woolly branches and dull green foliage. The oval leaves are about 30 mm long (1.18 in), the large and greenish pea flowers are streaked with fine black lines, and the club-shaped seed pods are up to 50 mm long (1.9 in).

The plant's flowers grow on long spikes at the ends of its branches. The flower greatly resembles a bird attached by its beak to the central stalk of the flowerhead. The Mauve flowers are partially covered in hairy lobes. 'Crotalaria cunninghamii' is non-allergenic and its pods are large and almost square and are covered in a soft, green hairy shell. It is used mainly as an ornamental flower.
