An exceedingly troublesome weed in grain fields of southeastern Washington, locally 

 known as "tarweed." The species is extremely variable and Suftsdorf segregates from it 

 three proposed new species, A. arenaria,b A. retrorsa, c and A. micrantha.c The characters 

 relied upon seem very slight and we question their value.
