Pineapple Weed (Matricaria discoidea): Although considered introduced by many sources, the FNA account indicates this species actually originates in northwestern North America and has spread from there. AKEPIC has it listed as an introduced species in the state. Only a few collections in ARCTOS (some under M. matricarioides). Many observations from throughout the region in the AKEPIC database. Occurrence away from areas of human disturbance is unclear.
