Daucus bicolor is similar to Daucus gutttatus but the whole of the central umbellule is coloured purple. The species was first collected by the famous English botanist John Sibthorpe when he journeyed through Greece and Anatolia in the 16th century. The flower was drawn and painted by the skilful  artist Ferdinand Bauer (vide infra) and appeared along with many other beautiful illustrations in the Flora Graeca Sibthorpiana.

A number of authorities consider that D. bicolor is a synonym of D. guttatus, but others have confirmed it as a separate species1,2.
