Calotis hispidula

Calotis hispidula, commonly known as hairy burr-daisy or bogan flea, is a small annual herb in the family Asteraceae endemic to inland Australia, occurring across arid and semi-arid parts of Western Australia, the Northern Territory, South Australia, Queensland, New South Wales, and Victoria. The plant typically grows 5 to 25 centimetres tall, forming a low rosette of stiffly hairy, oblanceolate to spathulate basal leaves 1 to 4 centimetres long with toothed or shallowly lobed margins. From the rosette arise several leafless or sparingly leaved scapes bearing solitary terminal flower heads about 1 centimetre across. Each capitulum has white to pale lilac ray florets surrounding a yellow disc that becomes globular as the fruit develops. The fruits are distinctive bristly burr-like achenes armed with rigid retrorse-barbed pappus bristles that readily attach to wool and clothing. It grows on heavy clay soils of floodplains, gilgai depressions, and seasonal swamps after rain.
