History
editThe species was first described by Ferdinand von Mueller. He was a botanist that was appointed chief botanist for the colony of Victoria in 1853. He discovered many Australian plants, including the showy burr daisy (Morris, 1974).
Distribution
editFound in areas of sandy plains and arid areas (Cunningham et al., 1992)(Seeds of Australia, 2018). It is found mostly within the west of New South Wales, although it is distributed also to the south of Victoria and South Australia (Cunningham et al. 1992).
It lives within sparse mulga, black blue bush and other shrub communities within the sandplains and dune fields (Cunningham et al. 1992).
Name meaning
editThe genus name, Calotis, comes from the Greek word kalos meaning beautiful. The specific name, cymbacantha, comes from the Greek word kymbe meaning boat and akantha meaning thorn and spine which refers to the boat-shaped shape of the seed (Morris, 1974),(Seeds of South Australia. 2018).
