Etymology: The name of this plant genus is a Latin borrowing from the Greek "kentaurion", which was used for centaury, a bitter medicinal herb. The Greek name is traditionally linked to Chiron, the wise centaur of myth, who was said to have used these plants to heal wounds, though the connection between the myth and the plant name is a story told by the ancients rather than something the word itself proves. The genus was named Centaurea in Latin, and the term was later adopted for the group of thistle-like flowers now grouped under it, including the cornflower and knapweeds. Those familiar blue cornflowers and bristly purple knapweeds are members of the same large family, a reminder that a single mythical name could cover plants of quite different appearances. Centaurea and centaury are doublets: two words that descend from the same source but reached English by different routes. "Centaury" is the older, more everyday name for the bitter herb, while "centaurea" stayed a botanical term, which explains why the two look so similar yet sound quite different.
