Iberian knapweed, Iberian starthistle

Publication: Syst. Veg. 3: 406. 1826.

Origin: Introduced from Eurasia

selected vouchers: WS

Notes: FNA19:"Iberian star thistle is considered to be a noxious weed in several states of the western United States. Weed control measures in Oregon and Washington have apparently eradicated the species in those states. Centaurea iberica is very similar to C. calcitrapa, from which it differs by its pappose cypselae and often more robust habit."

Chambers and Sundberg (2000) give author as Spreng.
