Derivation of the botanical name:

Centaurea, gets its name from the centaur, Chiron, who is said in mythology to have taught us the healing power of herbs.

The Hebrew name: דרדר, dardar, from Aramaic: דרדרא, dardara; Arabic: דרדאר, darda’ar. (Gen. 3:18, Hos. 10:8). In modern Arabic shauket el-dardar is applied to the star thistles or knapweeds.

  • The standard author abbreviation Boiss is used to indicate Pierre Edmond Boissier (1810–1885), a Swiss botanist, explorer and mathematician.
