TAXONOMY:The scientific name for spotted knapweed is Centaurea stoebe L. ssp. micranthos (Gugler) Hayek (Asteraceae). In North America, the name Centaurea maculosa has been misapplied to Centaurea stoebe ssp. micranthos, which is a polycarpic, perennial tetraploid that originated in eastern Europe [137]. Centaurea maculosa is a monocarpic, biennial diploid from central Europe. As of this writing (2001), Centaurea maculosa does not occur in North America [182]. The taxonomy of spotted knapweed is discussed in Ochsmann [137] and on the Centaurea website. Oschsmann [136] cites evidence of hybridization between spotted and diffuse knapweed (Centaurea diffusa) in at least 7 U.S. states. The hybrid is named Centaurea × psammogena Gayer.

FEDERAL LEGAL STATUS:No special status
OTHER STATUS:Spotted knapweed has been declared a noxious or restricted weed in at least 15 states in the U.S. and 4 Canadian provinces [213]. See the Invaders or Plants databases for current information.
